Examination Guidelines for 35 U.S.C. § 102(e), as amended by the American Inventors Protection Act of 1999, and further amended by the Intellectual Property and High Technology Technical Amendments Act of 2002, and 35 U.S.C. § 102(g) (Revised ) [1]

Alternative Text Version

This notice sets forth the interpretation by the United States Patent and Trademark Office (USPTO or Office) of 35 U.S.C. §§ 102(e) and 374, as amended by the American Inventors Protection Act of 1999 (AIPA) (Pub. L. 106-113, 113 Stat. 1501 (1999)), and as further amended by the Intellectual Property and High Technology Technical Amendments Act of 2002 (H.R. 2215) (Pub. L. 107-xxx (2002)). This notice also clarifies the Office's policy on prior art rejections based on 35 U.S.C. § 102(g).

Generally, 35 U.S.C. § 102(e), after enactment of the AIPA and H.R. 2215, is similar to the pre-AIPA § 102(e), with two significant differences, which may be summarized as: (1) in addition to U.S. patents, now certain publications of US and international applications may be applied as of their filing dates in a prior art rejection; and (2) certain international filing dates are now US filing dates under § 102(e), and US patents and certain application publications may now be applied as of these international filing dates in a prior art rejection.

Specifically, this notice provides guidance that prior art, as defined by § 102(e) of the patent code in effect on November 29, 2000, includes US patents, publications of US patent applications and World Intellectual Property Organization's (WIPO) publications of international applications, provided such references do not directly or indirectly result from an international application filed before November 29, 2000. If a US patent resulted from an international application filed before November 29, 2000, the US patent will have a prior art date per § 102(e) in effect prior to November 29, 2000, which is the earlier of the date of compliance with § 371(c)(1), (2) and (4) of the patent code (e.g. National Stage entry) or the filing date of the later-filed US application that claimed the benefit of the international application. A US or WIPO publication of an international application filed prior to November 29, 2000 will have no prior art effect under § 102(e). Such publications do, however, have prior art effect under § 102(a) or (b) as of their publication dates.

Furthermore, all pending US patent applications being examined, and all US patents being reexamined, or otherwise being contested, whenever filed, are subject to the amended version of § 102(e).

This notice also provides examples of the determination of § 102(e) dates for references based on the most common factual scenarios. The examples that best highlight the recent change to §§ 102(e) and 374 are the examples that involve a WIPO publication of an international application under PCT Article 21(2), a US publication of an international application, or a US patent derived from an international application.

The policy and practice set forth in the Official Gazette Notice entitled "Examination Guidelines for 35 U.S.C. § 102(e)(2), as amended by the American Inventors Protection Act of 1999," 1243 O.G. 1037 (Feb. 27, 2001) and guidelines provided in the Manual of Patent Examining Procedure (MPEP) concerning the changes made by the AIPA to 35 U.S.C. § 102(e) (e.g., MPEP 706.02(a), Part II; 901.03; 1895.01, Part E; 1896; and 2136 et seq., Eighth Edition (August 2001)) are superceded by this notice and should no longer be followed.

SIGNIFICANT PROVISIONS:

A. Effective Date Provisions of the Amendments.

The technical correction legislation in H.R. 2215 provides for the application of revised
35 U.S.C. § 102(e) in the examination of all applications, whenever filed, and the reexamination of, or other proceedings to contest, all patents. The filing date of the application is no longer relevant in determining what version of § 102(e) to apply in determining the patentability of that application, or the patent resulting from that application. The revised statutory provisions supercede all previous versions of §§ 102(e) and 374, with only one exception, which is when the potential reference is based on an international application filed prior to November 29, 2000 (discussed further in section D below). Furthermore, the provisions amending §§ 102(e) and 374 in H.R. 2215 are completely retroactive to the effective date of the relevant provisions in the AIPA (November 29, 2000).

B. US and WIPO application publications may have a § 102(e)(1) prior art date.

Paragraph (e) of 35 U.S.C. § 102 was amended by the AIPA to create two separate clauses, namely, § 102(e)(1) for publications of patent applications and § 102(e)(2) for patents. Section 102(e)(1), in combination with amended § 374, created a new category of prior art by providing prior art effect for certain publications of patent applications, including international applications, as of their effective United States filing dates (which will include certain international filing dates). Under H.R. 2215's revised
§ 102(e), an international filing date, which is on or after November 29, 2000, is a United States filing date for prior art purposes under 35 U.S.C. § 102(e) if the international application designated the United States and was published by the World Intellectual Property Organization (WIPO) under the Patent Cooperation Treaty (PCT) Article 21(2) in the English language. Publication under PCT Article 21(2) may result from a request for early publication by an international applicant or after the expiration of 18-months after the earliest claimed filing date in an international application. An applicant that has designated only the US would continue to be required to request publication from WIPO as the reservation under PCT Article 64(4) continues to be in effect for such applicants.

C. A patent from an international application may have a § 102(e)(2) prior art date of its international filing date.

Paragraph (e) of 35 U.S.C. § 102 was also amended by the AIPA to eliminate the reference to fulfillment of the 35 U.S.C. § 371(c)(1), (2) and (4) requirements. As a result, United States patents issued directly from international applications filed on or after November 29, 2000 will no longer be available as prior art under § 102(e) as of the date the requirements of § 371 (c)(1), (2) and (4) have been satisfied. Under § 102(e)(2), as amended by the AIPA and H.R. 2215, an international filing date, which is on or after November 29, 2000, is a United States filing date for purposes of determining the earliest effective prior art date of a patent if the international application designated the United States and was published in the English language under PCT Article 21(2) by WIPO.

D. International filing dates prior to November 29, 2000 cannot be used under § 102(e) for prior art purposes.

No international filing dates prior to November 29, 2000 may be relied upon as a prior art date under § 102(e) in accordance with the last sentence of the effective date provisions (reproduced below in section I). Patents issued directly, or indirectly, from international applications filed before November 29, 2000 may only be used as prior art based on the provisions of § 102(e) in effect before November 29, 2000. Thus, the date of such a prior art patent is the earliest of the date of compliance with 35 U.S.C. § 371(c)(1), (2) and (4), or the filing date of the later-filed US continuing application that claimed the benefit of the international application. Publications of international applications filed before November 29, 2000 (which would include WIPO publications and US publications of the National Stage (§ 371)) do not have a § 102(e) date at all. Specifically, under § 374, the international application must be filed on or after November 29, 2000 for its WIPO publication to be "deemed a publication under section 122(b)" and thus available as a possible prior art reference under § 102(e) as amended by the AIPA.

E. Additional requirements for international applications filed on or after November 29, 2000.

If an international application was filed on or after November 29, 2000, the international application must have designated the US and been published in English under PCT Article 21(2) by WIPO in order for its international filing date to be a US filing date for purposes of § 102(e) and be relied upon as a prior art date.

F. When an international application cannot serve as a bridge to an earlier-filed application.

International applications, which: (1) were filed prior to November 29, 2000, (2) did not designate the US, or (3) were not published in English under PCT Article 21(2) by WIPO, may not be used to reach back (bridge) to an earlier filing date through a priority or benefit claim for prior art purposes under 35 U.S.C. § 102(e).

DISCUSSION: Sections I -V below set forth the USPTO's examination procedures for the amendments to 35 U.S.C. § 102(e) made by the AIPA and H.R. 2215.

I) Statutory Language of 35 U.S.C. §§ 102(e) and 374:

Pre-AIPA § 102(e): Now, only applies to Patents derived from International Applications filed before November 29, 2000:

"A person shall be entitled to a patent unless -

(e) the invention was described in a patent granted on an application for patent by another filed in the United States before the invention thereof by the applicant for patent, or on an international application by another who has fulfilled the requirements of paragraphs (1), (2), and (4) of section 371(c) of this title before the invention thereof by applicant for patent, or".

Revised § 102(e): For examining all Applications, whenever filed, and for reexamining of all Patents, and for determining the prior art dates[2] of Patents and certain Application Publications:

A person shall be entitled to a patent unless-

(e) the invention was described in (1) an application for patent, published under section 122(b), by another filed in the United States before the invention by the applicant for patent or (2) a patent granted on an application for patent by another filed in the United States before the invention by the applicant for patent, except that an international application filed under the treaty defined in section 351(a) shall have the effects for the purposes of this subsection of an application filed in the United States only if the international application designated the United States and was published under Article 21(2) of such treaty in the English language; or

Pre-AIPA § 374: For WIPO Publications of International Applications filed prior to November 29, 2000:

The publication under the treaty of an international application shall confer no rights and shall have no effect under this title other than that of a printed publication.

Revised § 374: For WIPO Publications of International Applications filed on or after November 29, 2000:

The publication under the treaty defined in section 351(a) of this title, of an international application designating the United States shall be deemed a publication under section 122(b), except as provided in sections 102(e) and 154(d) of this title.

Effective Date Provisions for the amendments to §§ 102(e) and 374[3] , as amended by H.R. 2215:

Except as otherwise provided in this section, sections 4502 through 4504 and 4506 through 4507, and the amendments made by such sections, shall be effective as of November 29, 2000, and shall apply only to applications (including international applications designating the United States) filed on or after that date. The amendments made by section 4504 shall additionally apply to any pending application filed before November 29, 2000, if such pending application is published pursuant to a request of the applicant under such procedures as may be established by the Director. Except as otherwise provided in this section, the amendments made by section 4505 shall be effective as of November 29, 2000 and shall apply to all patents and all applications for patents pending on or filed after November 29, 2000. Patents resulting from an international application filed before November 29, 2000 and applications published pursuant to section 122(b) or Article 21(2) of the treaty defined in section 351(a) resulting from an international application filed before November 29, 2000 shall not be effective as prior art as of the filing date of the international application; however, such patents shall be effective as prior art in accordance with section 102(e) in effect on November 28, 2000.

II) Impact of Statutory Changes and Effective Date of the Changes

As shown above, 35 U.S.C. § 102(e) has been amended to have two separate clauses, namely, (e)(1) for publications of patent applications, and (e)(2) for patents.

With respect to revised 35 U.S.C. § 102(e)(1) and 35 U.S.C. § 374, a new category of prior art is created for publications of patent applications. This new category includes the following two types of published patent applications:

(1) US publications of patent applications filed in the United States by another which are published under § 122(b) of title 35, United States Code; and

(2) US and WIPO publications of international applications, filed on or after November 29, 2000, by another that designated the United States and were published in the English language under PCT Article 21(2) by WIPO.

In summary, under amended §§ 102(e)(1) and 374, certain publications of patent applications, including certain WIPO publications of international applications (under PCT Article 21(2)) which are filed on or after November 29, 2000, are considered to be prior art as of their earliest effective United States filing date. It is important to note that a US application publication of a National Stage of an international application or a WIPO publication of an international application under §§ 102(e)(1) and 374, as amended by H.R. 2215, can be prior art as of the international filing date if the international application had an international filing date on or after November 29, 2000, designated the United States, and was published in English under PCT Article 21(2) by WIPO. Prior to the AIPA amendments to §§ 102(e) and 374, a WIPO publication of an international application could only be prior art under § 102(a) or (b) as of the publication date (and there were no US application publications).

Paragraph (e) of 35 U.S.C. § 102 was also amended to modify what US patents are available as prior art under this subsection. Section 102(e)(2) no longer recognizes the date of fulfillment of the 35 U.S.C. § 371(c)(1), (2) and (4) requirements for prior art purposes. Section § 102(e)(2), however, considers an international filing date that is on or after November 29, 2000 as a United States filing date for purposes of determining the earliest effective prior art date of a patent if the international application designated the United States and was published in the English language under PCT Article 21(2) by WIPO.

The AIPA and H.R. 2215 also establish when the amendments to §§ 102(e) and 374 must be applied. First, the AIPA and H.R. 2215 set forth that the amendments to § 102(e) apply to all applications being examined and all patents under reexamination. See the third sentence of § 4508 of the AIPA, as amended by H.R. 2215 (addressing § 4505 of the AIPA). In other words, the revised version of § 102(e) is completely retroactive, and it applies to all applications, no matter when filed, and all patents, with only one exception, which pertains to applying, as prior art under § 102(e), patents or publications based on international applications filed prior to November 29, 2000. Further, the amendments to § 374, which "deems" certain WIPO publications of international applications under PCT Article 21(2) as US publications of applications filed under 35 U.S.C. § 111(a), are only effective for international applications filed on or after November 29, 2000. Therefore, an international application must be filed on or after November 29, 2000 for its WIPO publication to be "deemed a publication under section 122(b)," and thus available as a possible prior art reference under § 102(e)(1).

III) Prior Art Rejections based on 35 U.S.C. § 102(g)

35 U.S.C. § 102(g) issues such as conception, reduction to practice and diligence, while more commonly applied to interference matters, also arise in other contexts.

35 U.S.C. § 102(g) may form the basis for an ex parte rejection if: (1) the subject matter at issue has been actually reduced to practice by another before the applicant's invention, and (2) there has been no abandonment, suppression or concealment. See, e.g., Amgen, Inc. v. Chugai Pharmaceutical Co., 927 F.2d 1200, 1205, 18 USPQ2d 1016, 1020 (Fed. Cir. 1991); New Idea Farm Equipment Corp. v. Sperry Corp., 916 F.2d 1561, 1566, 16 USPQ2d 1424, 1428 (Fed. Cir. 1990); E.I. DuPont de Nemours & Co. v. Phillips Petroleum Co., 849 F.2d 1430, 1434, 7 USPQ2d 1129, 1132 (Fed. Cir. 1988); Kimberly_Clark v. Johnson & Johnson, 745 F.2d 1437, 1444-46, 223 USPQ 603, 606-08 (Fed. Cir. 1984). To qualify as prior art under 35 U.S.C. § 102(g), however, there must be evidence that the subject matter was actually reduced to practice, in that conception alone is not sufficient. See Kimberly Clark, 745 F.2d at 1445, 223 USPQ at 607. While the filing of an application for patent is a constructive reduction to practice, the filing of an application does not in itself provide the evidence necessary to show an actual reduction to practice of any of the subject matter disclosed in the application as is necessary to provide the basis for an ex parte rejection under 35 U.S.C. § 102(g). Thus, absent evidence showing an actual reduction to practice (which is generally not available during ex parte examination), the disclosure of a United States patent application publication or patent falls under 35 U.S.C. § 102(e) and not under 35 U.S.C. § 102(g). Cf. In re Zletz, 893 F.2d 319, 323, 13 USPQ2d 1320, 1323 (Fed. Cir. 1990) (the disclosure in a reference United States patent does not fall under 35 U.S.C. § 102(g) but under 35 U.S.C. § 102(e)).

In addition, subject matter qualifying as prior art only under 35 U.S.C. § 102(g) may also be the basis for an ex parte rejection under 35 U.S.C. 103. See In re Bass, 474 F.2d 1276, 1283, 177 USPQ 178, 183 (CCPA 1973) (in an unsuccessful attempt to utilize a 37 CFR 1.131 affidavit relating to a combination application, applicants admitted that the subcombination screen of a copending application which issued as a patent was earlier conceived than the combination). 35 U.S.C. § 103(c), however, states that subsection (g) of 35 U.S.C. § 102 will not preclude patentability where subject matter developed by another person, that would otherwise qualify under 35 U.S.C. § 102(g), and the claimed invention of an application under examination were owned by the same person or subject to an obligation of assignment to the same person at the time the invention was made. See MPEP §§ 706.02(l) and 2146 (Eighth Edition (Aug. 2001)).

For additional examples of 35 U.S.C. § 102(g) issues such as conception, reduction to practice and diligence outside the context of interference matters, see In re Costello, 717 F.2d 1346, 219 USPQ 389 (Fed. Cir. 1983) (discussing the concepts of conception and constructive reduction to practice in the context of a declaration under 37 CFR 1.131), and Kawai v. Metlesics, 480 F.2d 880, 178 USPQ 158 (CCPA 1973) (holding constructive reduction to practice for priority under 35 U.S.C. § 119 requires meeting the requirements of 35 U.S.C. §§ 101 and 112).

IV) Examination Procedures under 35 U.S.C. §§ 102(e) and 374

(1) Determine the effective filing date(s) of the application being examined.

See the Manual of Patent Examining Procedure (MPEP), sections 706.02, 1893.03(b), 1893.03(c), 1895 and 1895.01, Eighth Edition (Aug. 2001) as revised by this notice.

(2) Determine and perform an appropriate prior art search.

The Examiner should search for the most relevant prior art under 35 U.S.C. §§ 102 and 103, including US and WIPO publications of patent applications, and USpatents accorded prior art dates under § 102(e).

(3) Determine if the potential reference under § 102(e) is "by another."

The inventive entity of the application must be different than that of the reference in order to apply a reference under § 102(e). Note that, where there are joint inventors, only one inventor need be different for the inventive entities to be different and a rejection under § 102(e) may be applicable even if there are some common inventors. See MPEP 706.02(a), Eighth Edition (Aug. 2001) as revised by this notice.

(4) Determine the appropriate § 102(e) date for each potential reference by following the guidelines below and examples set forth under Part V:

(a) The potential reference must be a US patent, a US application publication (35 U.S.C. § 122(b)) or a WIPO publication of an international application under PCT Article 21(2) in order to apply the reference under § 102(e).

(b) Determine if the potential reference resulted from, or claimed the benefit of, an international application. If the reference does, go to step (c) below.

The § 102(e) date of a reference that did not result from, nor claimed the benefit of, an international application is its earliest effective US filing date, taking into consideration any proper priority or benefit claims to prior US applications under §§ 119(e) or 120 if the prior application(s) properly supports the subject matter used to make the rejection. See MPEP 706.02(a), Eighth Edition (Aug. 2001) as revised by this notice.

(c) If the potential reference resulted from, or claimed the benefit of, an international application, the following must be determined:

i. If the international application meets the following three conditions:

1. an international filing date on or after November 29, 2000;

2. designated the United States; and

3. published under PCT Article 21(2) in English,

the international filing date is a US filing date for prior art purposes under § 102(e). If such an international application properly claims benefit to an earlier-filed US or international application, or priority to an earlier-filed US provisional application, apply the reference under § 102(e) as of the earlier filing date, assuming all the conditions of §§ 102(e), 119(e), 120, or 365(c) are met. Note, where the earlier application is an international application, the earlier international application must satisfy the same three conditions (i.e., filed on or after November 29, 2000, designated the US and had been published in English under PCT Article 21(2)).

ii. If the international application was filed on or after November 29, 2000, but did not designate the United States or was not published in English under PCT Article 21(2), do not treat the international filing date as a US filing date for use under 35 U.S.C. § 102(e) as a prior art date. In this situation, do not apply the reference as of its international filing date, its date of completion of the § 371(c)(1), (2) and (4) requirements, or any earlier filing date to which such an international application claims benefit or priority. The reference may be applied under § 102(a) or (b) as of its publication date, or § 102(e) as of any later US filing date of an application that properly claimed the benefit of the international application (if applicable).

iii. If the international application has an international filing date prior to November 29, 2000, apply the reference under the provisions of §§ 102 and 374, prior to the AIPA amendments:

1. For US patents, apply the reference under § 102(e) as of the earlier of the date of completion of the requirements of § 371(c)(1), (2) and (4) or the filing date of the later-filed US application that claimed the benefit of the international application.

2. For US application publications and WIPO publications of international applications under PCT Article 21(2), never apply these references under § 102(e). These references may be applied as of their publication dates under § 102(a) or (b).

3. For US application publications of applications that claim the benefit of an international application filed prior to November 29, 2000, apply the reference under § 102(e) as of the actual filing date of the later-filed US application that claimed the benefit of the international application.

iv. Examiners should be aware that although a publication of, or a US Patent issued from, an international application may not have a § 102(e) date at all, or may have a § 102(e) date that is after the effective filing date of the application being examined (so it is not "prior art"), the corresponding WIPO publication of an international application will likely have an earlier § 102(a) or (b) date.

(d) Foreign applications' filing dates that are claimed (via 35 U.S.C. §§ 119(a)-(d) or 365(a)) in applications, which have been published as US or WIPO application publications or patented in the US, may not be used as § 102(e) dates for prior art purposes. This would include international filing dates claimed as foreign priority dates under 35 U.S.C. § 365(a).

(5) Determine whether 35 U.S.C. § 103(c) common assignee considerations apply.

If a § 102(e) reference is applied in an obviousness rejection under 35 U.S.C. § 103(a) (including provisional rejections) in an application filed on or after November 29, 1999[4] , the examiner should ascertain whether there is evidence that the claimed invention and the reference were owned by the same person, or subject to an obligation of assignment to the same person, at the time the claimed invention was made. A clear statement of entitlement to the prior art exclusion by applicant(s) or a registered practitioner would be sufficient evidence to establish the prior art exclusion. A double patenting rejection, however, based on the § 102(e) reference could be applied, if appropriate, even if the reference is disqualified from being used a rejection under § 103(a). See MPEP 706.02(l), Eighth Edition (Aug. 2001).

(6) Apply the reference(s) under §§ 102 or 103, based on the provision of § 102 that gives the best prior art date for the disclosure. If a reference is prior art under both §§ 102 (a) and (e), but not § 102(b), the reference should be applied under both provisions.

(a) Examiners should provide a copy of the appropriate statutory language under which the rejection is made in the first Office action utilizing such a rejection. Only revised (October 2002, or more current) Form Paragraphs pertaining to § 102(e) should be used.

(7) Final rejection practice: If a second or subsequent action contains a new ground of rejection necessitated by the change to 35 U.S.C. § 102(e) that was not also necessitated by an amendment to the claims or as a result of certain information disclosure statements, that action cannot be made final. See MPEP 706.07(a), Eighth Edition (Aug. 2001).

V) Examples

In order to illustrate the prior art dates of US and WIPO publications of patent applications and United States patents under § 102(e), nine examples are presented below. The examples only cover the most common factual situations that might be encountered when determining the § 102(e) date of a reference. Examples 1 and 2 involve only US application publications and US patents. Example 3 involves a priority claim to a foreign patent application. Examples 4-9 involve international applications. The time lines in the examples below show the history of the prior art references that could be applied against the claims of the application under examination, or the patent under reexamination.

The dates in the examples below are arbitrarily used and are presented for illustrative purposes only. Therefore, correlation of patent grant dates with Tuesdays or application publication dates with Thursdays may not be portrayed in the examples.

Example 1: Reference Publication and Patent of § 111(a) Application with no Priority/Benefit Claims.

For reference publications and patents of patent applications filed under 35 U.S.C. § 111(a) with no claim for the benefit of, or priority to, a prior application, the prior art dates under § 102(e) accorded to these references are the earliest effective United States filing date. Thus, a publication and patent of a § 111(a) application, which does not claim any benefit under either 35 U.S.C. §§ 119(e), 120 or 365(c), would be accorded the application's actual filing date as its prior art date under § 102(e).

[Alternative Text: Graphic representation of time line of Example 1 depicting: a § 111(a) application was filed with no claims for benefit/priority on December 8, 2000; a publication of the § 111(a) application under § 122(b) on June 12, 2002 and a patent granted on the application on December 3, 2002.]

The § 102(e)(1) date for Publication is: 08 Dec 2000

The § 102(e)(2) date for the Patent is: 08 DEC 2000

Example 2: Reference Publication and Patent of § 111(a) Application with Priority/Benefit Claim to a Prior US Provisional or Nonprovisional Application.

For reference publications and patents of patent applications filed under 35 U.S.C. § 111(a), the prior art dates under § 102(e) accorded to these references are the earliest effective United States filing dates. Thus, a publication and patent of a § 111(a) application, which claims priority under 35 U.S.C. § 119(e) to a prior US provisional application or claims the benefit under 35 U.S.C. § 120 of a prior nonprovisional application, would be accorded the earlier filing date as its prior art date under § 102(e), assuming the earlier-filed application has proper support for the subject matter as required by §§ 119(e) or 120.

[Alternative Text: Graphic representation of time line of Example 2 depicting: a first § 111(a) application was filed January 1, 2000 which is prior to the effective date of 102(e) (11/29/00); a second application under § 111(a) which claims the benefit or priority of the prior application was filed on January 1, 2001; a publication of the second application under § 122(b) on July 5, 2001; and a patent was granted on the second application on December 2, 2002.]

The § 102(e)(1) date for Publication is: 01 Jan 2000

The § 102(e)(2) date for the Patent is: 01 Jan 2000

Example 3: Reference Publication and Patent of § 111(a) Application with § 119(a)-(d) Benefit Claim to a Prior Foreign Application.

For reference publications and patents of patent applications filed under 35 U.S.C. § 111(a), the prior art dates under § 102(e) accorded to these references are the earliest effective United States filing dates. No benefit of the filing date of the foreign application is given under § 102(e) for prior art purposes (In re Hilmer, 149 USPQ 480 (CCPA 1966)). Thus, a publication and patent of a § 111(a) application, which claims benefit under 35 U.S.C. § 119(a)-(d) to a prior foreign-filed application, would be accorded its United States filing date as its prior art date under § 102(e).

The § 102(e)(1) date for Publication is: 21 Jun 1999

The § 102(e)(2) date for the Patent is: 21 Jun 1999

Example 4: References based on the National Stage (§ 371) of an International Application filed on or after November 29, 2000 and which was published in English under PCT Article 21(2).

All references, whether the WIPO publication, the US application publication or the US patent, of an international application (IA) that was filed on or after November 29, 2000, designated the US, and was published in English under PCT Article 21(2) by WIPO, have the § 102(e) prior art date of the international filing date or earlier effective US filing date. No benefit of the international filing date (nor any US filing dates prior to the IA), however, is given for § 102(e) prior art purposes if the IA was published under PCT Article 21(2) in a language other than English.

[Image of Example 4]

[Alternative Text: Graphic representation of Timeline of Example 4 depicting: an international application (IA) was filed in Swedish, US designated on January 1, 2001; the international application publication by WIPO in English was on July 1, 2002; the § 371(c)(1)(2) and (4) fulfullment date was June 1, 2003; a publication by the USPTO under § 122(b) on July 1, 2003; and a patent granted on § 371 application on November 1, 2003.]

The § 102(e)(1) date for the IA publication by WIPO is: 01 Jan 2001

The § 102(e)(1) date for Publication by USPTO is: 01 Jan 2001

The § 102(e)(2) date for the Patent is: 01 Jan 2001

Additional Priority/Benefit Claims:

1. If a later-filed US nonprovisional (§ 111(a)) application claimed the benefit of the IA in the example above, the § 102(e) date of the patent or publication of the later-filed US application would be the international filing date, assuming the earlier-filed IA has proper support for the subject matter relied upon as required by § 120.

2. If the IA properly claimed priority to an earlier-filed US provisional (§ 111(b)) application or the benefit of an earlier-filed US nonprovisional (§ 111(a)) application, the § 102(e) date for all the references would be the filing date of the earlier-filed US application, assuming the earlier-filed application has proper support for the subject matter relied upon as required by §§ 119(e) or 120.

Example 5: References based on the National Stage (§ 371) of an International Application filed on or after November 29, 2000 and which was not published in English under PCT Article 21(2).

All references, whether the WIPO publication, the US application publication or the US patent, of an international application (IA) that was filed on or after November 29, 2000 but wasnot published in English under PCT Article 21(2), have no § 102(e) prior art date at all. According to § 102(e), no benefit of the international filing date (nor any US filing dates prior to the IA) is given for § 102(e) prior art purposes if the IA was published under PCT Article 21(2) by WIPO, in a language other than English regardless of whether the international application entered the National Stage. Such references may be applied under § 102(a) or (b) as of their publication dates, but never under § 102(e).

[Alternative Text: Graphic representation of Timeline of Example 5 depicting: an international application (IA) was filed, US designated on January 1, 2001; the international application publication by WIPO not in English was on July 1, 2002; the § 371(c)(1)(2) and (4) fulfullment date is June 1, 2003; a publication by the USPTO under § 122(b) was on October 2, 2003 and a patent was granted on § 371 application on November 2, 2004.]

The § 102(e)(1) date for the IA publication by WIPO is: None

The § 102(e)(1) date for Publication by USPTO is: None

The § 102(e)(2) date for the Patent is: None

The IA publication by WIPO can be applied under § 102(a) or (b) as of its publication date (01 July 2002).

Additional Priority/Benefit Claims:

1. If the IA properly claimed priority/benefit to any earlier-filed US application (whether provisional or nonprovisional), there would still be no § 102(e) date for all the references.

2. If a later-filed US nonprovisional (§ 111(a)) application claimed the benefit of the IA in the example above, the § 102(e) date of the patent or publication of the later-filed US application would be the actual filing date of the later-filed US application.

Example 6: References based on the National Stage (§ 371) of an International Application filed prior to November 29, 2000 (language of the publication under PCT Article 21(2) is not relevant)

The reference US patent issued from an international application (IA) that was filed prior to November 29, 2000 has a § 102(e) prior art date of the date of fulfillment of the requirements of 35 U.S.C. § 371(c)(1), (2) and (4). This is the pre-AIPA § 102(e). The application publications, both the WIPO publication and the US publication, published from an international application that was filed prior to November 29, 2000, do not have any § 102(e) prior art date. According to the effective date provisions as amended by H.R. 2215, the amendments to §§ 102(e) and 374 are not applicable to international applications having international filing dates prior to November 29, 2000. The application publications can be applied under § 102(a) or (b) as of their publication dates.

[Alternative Text: Graphic representation of Timeline of Example 6 depicting: an international application (IA) was filed in Canada, US designated on January 1, 2000; the international application publication by WIPO in any language was on July 1, 2001; the National Stage § 371(c)(1)(2)(4) fulfillment date was July 1, 2002; voluntary publication by the USPTO under § 122(b) on October 3, 2002; a patent granted on § 371 application on November 1, 2003.]

The § 102(e)(1) date for the IA publication by WIPO is: None

The § 102(e)(1) date for Publication by USPTO is: None

The § 102(e) date for the Patent is: 01 July 2002

The IA publication by WIPO can be applied under § 102(a) or (b) as of its publication date (01 July 2001).

Additional Priority/Benefit Claims:

1. If the IA properly claimed priority/benefit to any earlier-filed US application (whether provisional or nonprovisional), there would still be no § 102(e)(1) date for the US and WIPO application publications, and the § 102(e) date for the patent will still be 01 July 2002 (the date of fulfillment of the requirements under § 371(c)(1), (2) and (4)).

2. If a later-filed US nonprovisional (§ 111(a)) application claimed the benefit of the IA in the example above, the § 102(e)(1) date of the application publication of later-filed US application would be the actual filing date of the later-filed US application, and § 102(e) date of the patent of the later-filed US application would be 01 July 2002 (the date that the earlier-filed IA fulfilled the requirements of § 371(c)(1), (2) and (4)).

3. If the patent was based on a later-filed US application that claimed the benefit of the international application and the later filed US application's filing date is before the date the requirements of 35 U.S.C. 371(c)(1)(2) and (4) were fulfilled (if fulfilled at all), the 102(e) date of the patent would be the filing date of the later-filed US application that claimed the benefit of the international application.

Example 7: References based on a§ 111(a) Application which is a Continuation of an International Application, which was filed on or after November 29, 2000, designated the U.S. and was published in English under PCT Article 21(2).

All references, whether the WIPO publication, the US application publication or the US patent of, or claiming the benefit of, an international application (IA) that was filed on or after November 29, 2000, designated the US and was published in English under PCT Article 21(2) by WIPO, have the § 102(e) prior art date of the international filing date or earlier effective US filing date. No benefit of the international filing date (nor any US filing dates prior to the IA), however, is given for § 102(e) purposes if the IA was published under PCT Article 21(2) by WIPO in a language other than English.

[Image of Example 7]

[Alternative Text: Graphic representation of Timeline of Example 7 depicting: an international application (IA) was filed, US designated on March 1, 2001; the international application publication by WIPO in English was on September 1, 2002; a § 111(a) application claiming the benefit of the IA under §365(c) was filed May 1, 2003; publication of the § 111(a) application by the USPTO was on July 1, 2003; and a patent granted on § 111(a) application on November 1, 2004.]

The § 102(e)(1) date for the IA publication by WIPO is: 01 Mar 2001

The § 102(e)(1) date for Publication by USPTO is: 01 Mar 2001

The § 102(e)(2) date for the Patent is: 01 Mar 2001

Additional Priority/Benefit Claims:

1. If the IA properly claimed priority to an earlier-filed US provisional (§ 111(b)) application or the benefit of an earlier-filed US nonprovisional (§ 111(a)) application, the § 102(e) date for all the references would be the filing date of the earlier-filed US application, assuming the earlier-filed application has proper support for the subject matter relied upon as required by §§ 119(e) or 120 and 365(c).

2. If a second, later-filed US nonprovisional (§ 111(a)) application claimed the benefit of the § 111(a) application in the example above, the § 102(e) date of the patent or publication of the second, later-filed US application would still be the international filing date of the IA, assuming the earlier-filed IA has proper support for the subject matter relied upon as required by § 120.

Example 8: References based on a§ 111(a) Application which is a Continuation of an International Application, which was filed on or after November 29, 2000 and was not published in English under PCT Article 21(2)

Both the US publication and the US patent of the § 111(a) continuation of an international application (IA) that was filed on or after November 29, 2000 but was not published in English under PCT Article 21(2) by WIPO have the § 102(e) prior art date of its actual US filing date under §111(a). No benefit of the international filing date (nor any US filing dates prior to the IA) is given for § 102(e) purposes if the IA was published under PCT Article 21(2) in a language other than English. The IA publication under PCT Article 21(2) does not have a prior art date under § 102(e)(1) because the IA was not published in English under PCT Article 21(2). The IA publication under PCT Article 21(2) can be applied under § 102(a) or (b) as of its publication date.

[Alternative Text: Graphic representation of Timeline of Example 8 depicting: an international application (IA) was filed, US designated on March 1, 2001; the international application publication by WIPO not in English was on September 1, 2002; the § 111(a) application claiming the benefit of the IA under §365(c) was filed May 1, 2003; publication by the USPTO under § 111(a) was on July 1, 2003; and a patent granted on § 111(a) application was on November 1, 2004.]

The § 102(e)(1) date for the IA publication by WIPO is: None

The § 102(e)(1) date for Publication by USPTO is: 01 May 2003

The § 102(e)(2) date for the Patent is: 01 May 2003

The IA publication by WIPO can be applied under § 102(a) or (b) as of its publication date (01 Sept 2002).

Additional Priority/Benefit Claims:

1. If the IA properly claimed priority/benefit to any earlier-filed US application (whether provisional or nonprovisional), there would still be no § 102(e)(1) date for the IA publication by WIPO, and the US application publication and patent would still have a § 102(e) date of the actual filing date of the later-filed § 111(a) application in the example above (01 May 2003).

2. If a second, later-filed US nonprovisional (§ 111(a)) application claimed the benefit of the § 111(a) application in the example above, the § 102(e) date of the patent or publication of the second, later-filed US application would still be the actual filing date of the § 111(a) application in the example above (01 May 2003).

Example 9: References based on a § 111(a) Application which is a Continuation (filed prior to any entry of the National Stage) of an International Application, which was filed prior to November 29, 2000 (language of the publication under PCT Article 21(2) is not relevant)

Both the US publication and the US patent of the § 111(a) continuation (filed prior to any entry of the National Stage)of an international application (IA) that was filed prior to November 29, 2000 have the § 102(e) prior art date of its actual US filing date under §111(a). No benefit of the international filing date (nor any US filing dates prior to the IA) is given for § 102(e) prior art purposes if the IA was filed prior to November 29, 2000. The IA publication under PCT Article 21(2) does not have a prior art date under § 102(e)(1) because the IA was filed prior to November 29, 2000. The IA publication under PCT Article 21(2) can be applied under § 102(a) or (b) as of its publication date.

The § 102(e)(1) date for the IA publication by WIPO is: None

The § 102(e)(1) date for Publication by USPTO is: 01 DEC 2000

The § 102(e) date for the Patent is: 01 DEC 2000

The IA publication by WIPO can be applied under § 102(a) or (b) as of its publication date (01 Sept 2000).

Additional Priority/Benefit Claims:

1. If the IA properly claimed priority/benefit to any earlier-filed US application (whether provisional or nonprovisional), there would still be no § 102(e)(1) date for the IA publication by WIPO, and the US application publication and patent would still have a § 102(e) date of the actual filing date of later-filed § 111(a) application in the example above (01 DEC 2000).

2. If a second, later-filed US nonprovisional (§ 111(a)) application claimed the benefit of § 111(a) application in the example above, the § 102(e) date of the patent or publication of the second, later-filed US application would still be the actual filing date of the § 111(a) application in the example above (01 DEC 2000).

[1] An original version of this Notice, signed on November 4, 2002, was posted on the Office's web site, and disseminated in paper copy form as a Pre-OG Notice as it was expected that the Notice would soon publish in the Official Gazette. In view of comments received, however, this revised version of the Notice additionally includes a clarification of Office policy in "(7) Final Rejection Practice" in Section IV of the Discussion portion, some further applicability notes in Examples 5 and 6 in Section V of the Discussion portion, and some minor edits. In addition, Item B of the Significant Provisions portion, the third paragraph of Section II of the Discussion portion and part (c)(ii) of "(4) Determine the appropriate § 102(e) date for each potential reference by following the guidelines below and examples set forth under Part V" in Section IV of the Discussion portion have been revised to note that the filing dates of international applications that designate the US (which are filing dates in the US) are only treated as prior art dates under 35 U.S.C. § 102(e) under certain circumstances. This revised Notice signed December 11, 2002, therefore, supercedes the original Notice.

[2] If the reference is a patent based on an International Application filed prior to November 29, 2000, § 102(e) prior to
the AIPA is used to determine its § 102(e) prior art date.

[3] The amendments to § 102(e) were set forth in section 4505 of the AIPA, as amended by H.R. 2215. The amendments
to § 374 were set forth in section § 4507 of the AIPA, as amended by H.R. 2215.

[4] The revision to 35 U.S.C. § 103(c) was made in § 4807 of the AIPA and is applicable only to applications filed on or
after November 29, 1999.
