2136.01 Status of Unpublished or Published as Redacted U.S. Application as a Reference Under Pre-AIA 35 U.S.C. 102(e) [R-10.2019]

[Editor Note: This MPEP section is not applicable to applications subject to examination under the first inventor to file (FITF) provisions of the AIA as set forth in 35 U.S.C. 100 (note). See MPEP § 2159 et seq. to determine whether an application is subject to examination under the FITF provisions, and MPEP § 2150 et seq. for examination of applications subject to those provisions.]

If an earlier filed, copending, and unpublished U.S. patent application discloses subject matter which would anticipate the claims in a later filed pending U.S. application which has a different inventive entity, the examiner should determine whether a provisional rejection under pre-AIA 35 U.S.C. 102(e) of the later filed application can be made. In addition, a provisional rejection under pre-AIA 35 U.S.C. 102(e) may be made, in certain circumstances as described below, if the earlier filed, pending application has been published as redacted (37 CFR 1.217) and the subject matter relied upon in the rejection is not supported in the redacted publication of the patent application.

In addition to U.S. patents and SIRs, certain U.S. application publications and certain international application publications are also available as prior art under pre-AIA 35 U.S.C. 102(e) as of their effective U.S. filing dates (which will include certain international filing dates).

If there is no common assignee, common applicant, or common inventor and the application was not published pursuant to 35 U.S.C. 122(b), the confidential status of applications under 35 U.S.C. 122(a) must be maintained and no rejection can be made relying on the earlier filed, unpublished application, or subject matter not supported in a redacted application publication, as prior art under pre-AIA 35 U.S.C. 102(e). For applications subject to pre-AIA 35 U.S.C. 102(g), if the filing dates of the applications are within 6 months of each other (3 months for simple subject matter) then interference may be proper. See MPEP Chapter 2300. If the application with the earliest effective U.S. filing date will not be published pursuant to 35 U.S.C. 122(b), it must be allowed to issue once all the statutory requirements are met. After the patent has issued, it may be used as a reference in a rejection under pre-AIA 35 U.S.C. 102(e) in the still pending application as appropriate. See MPEP § 2136et seq.

Based on the assumption that an application will ripen into a U.S. patent (or into an application publication), it is permissible to provisionally reject a later application over an earlier filed, and unpublished, application under pre-AIA 35 U.S.C. 102(e) when there is a common assignee, applicant, or inventor. See, e.g., In re Irish, 433 F.2d 1342, 167 USPQ 764 (CCPA 1970). In addition, a provisional pre-AIA 35 U.S.C. 102(e) rejection may be made if the earlier filed copending U.S. application has been published as redacted (37 CFR 1.217) and the subject matter relied upon in the rejection is not supported in the redacted publication of the patent application. Such a provisional rejection “serves to put applicant on notice at the earliest possible time of the possible prior art relationship between copending applications” and gives applicant the fullest opportunity to overcome the rejection by amendment or submission of evidence. In addition, since both applications are pending and usually have the same assignee, more options are available to applicant for overcoming the provisional rejection than if the other application were already issued. Ex parte Bartfeld, 16 USPQ2d 1714 (Bd. Pat. App. & Int. 1990) aff’d on other grounds, 925 F.2d 1450, 17 USPQ2d 1885 (Fed. Cir. 1991). Note that provisional rejections over pre-AIA 35 U.S.C. 102(e) are only authorized when there is a common inventor or assignee, otherwise the copending application prior to publication must remain confidential.

Therefore, if (1) at least one common inventor or applicant exists between the applications or the applications are commonly assigned, and (2) the effective filing dates are different; then a provisional rejection of the later-filed application should be made. The provisional rejection is appropriate in circumstances where, if the earlier-filed application is published or becomes a patent, it would constitute actual prior art under 35 U.S.C. 102. Because the earlier-filed application is not published at the time of the rejection, the rejection must be provisionally made under pre-AIA 35 U.S.C. 102(e).

A provisional rejection under pre-AIA 35 U.S.C. 102(e) can be overcome in the same manner that a pre-AIA 35 U.S.C. 102(e) rejection can be overcome. See MPEP § 2136.05. The provisional rejection can also be overcome by abandoning the applications and filing a new application containing the subject matter of both. Form paragraph 7.15.01.fti should be used when making a provisional rejection under pre-AIA 35 U.S.C. 102(e).

For applications filed on or after November 29, 1999 or pending on or after December 10, 2004, a provisional rejection under pre-AIA 35 U.S.C. 103(a) using prior art under pre-AIA 35 U.S.C. 102(e) is not proper if the application contains evidence that the application and the prior art reference 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 pre-AIA 35 U.S.C. 103(c).

In addition, certain non-commonly owned references may be disqualified from being applied in a rejection under pre-AIA 35 U.S.C. 103(a) due to the Cooperative Research and Technology Enhancement Act of 2004 (CREATE Act) (Public Law 108-453; 118 Stat. 3596 (2004)), which was enacted on December 10, 2004 and was effective for all patents granted on or after December 10, 2004.

See MPEP §§ 2146-2146.03 for information pertaining to prior art disqualified under pre-AIA 35 U.S.C. 103(c), evidence of common ownership, and examination procedure with respect to pre-AIA 35 U.S.C. 103(c); see MPEP § 2146.03(a) for a discussion of provisional rejections under pre-AIA 35 U.S.C. 103(a) using provisional prior art under pre-AIA 35 U.S.C. 102(e).

Pre-AIA 35 U.S.C.103(c), as amended by the CREATE Act, continues to apply only to subject matter which qualifies as prior art under pre-AIA 35 U.S.C. 102(e), (f) or (g), and which is being relied upon in a rejection under 35 U.S.C. 103. It does not apply to or affect subject matter which is applied in a rejection under pre-AIA 35 U.S.C. 102 or a double patenting rejection (see 37 CFR 1.78(c) and MPEP § 804). In addition, if the subject matter qualifies as prior art under any other subsection of pre-AIA 35 U.S.C. 102 (e.g., pre-AIA 35 U.S.C. 102(a) or (b)) it will not be disqualified as prior art under pre-AIA 35 U.S.C. 103(c). See also MPEP § 2146et seq. for information relating to rejections under pre-AIA 35 U.S.C. 103 and evidence of joint research agreements.

2136.02 Content of the Prior Art Available Against the Claims [R-10.2019]

[Editor Note: This MPEP section is not applicable to applications subject to examination under the first inventor to file (FITF) provisions of the AIA as set forth in 35 U.S.C. 100 (note). See MPEP § 2159 et seq. to determine whether an application is subject to examination under the FITF provisions, and MPEP § 2150 et seq. for examination of applications subject to those provisions.]

Under pre-AIA 35 U.S.C. 102(e), the entire disclosure of a U.S. patent, a U.S. patent application publication, or an international application publication having an earlier effective U.S. filing date (which will include certain international filing dates) can be relied on to reject the claims. Sun Studs, Inc. v. ATA Equip. Leasing, Inc., 872 F.2d 978, 983, 10 USPQ2d 1338, 1342 (Fed. Cir. 1989). See MPEP § 2120.01.

When a U.S. patent, a U.S. patent application publication, or an international application publication is used to reject claims under pre-AIA 35 U.S.C. 102(e), the disclosure relied on in the rejection must be present in the issued patent or application publication. It is the earliest effective U.S. filing date (which will include certain international filing dates) of the U.S. patent or application publication being relied on as the critical reference date and subject matter not included in the patent or application publication itself can only be used when that subject matter becomes public. Portions of the patent application which were canceled are not part of the patent or application publication and thus cannot be relied on in a pre-AIA 35 U.S.C. 102(e) rejection over the issued patent or application publication. Ex parte Stalego, 154 USPQ 52 (Bd. App. 1966). Similarly, subject matter that is disclosed in an abandoned, unpublished parent application but was not carried over into the child patent or application publication may not be relied on as prior art under pre-AIA 35 U.S.C. 102(e). In re Klesper, 397 F.2d 882, 886, 158 USPQ 256, 258 (CCPA 1968). See MPEP § 901.02 for more information on availability of abandoned applications as prior art. Likewise, subject matter which is disclosed in a parent application, but not included in the child continuation-in-part (CIP) cannot be relied on in a pre-AIA 35 U.S.C. 102(e) rejection over the issued or published CIP. In re Lund, 376 F.2d 982, 153 USPQ 625 (CCPA 1967) (The examiner made a pre-AIA 35 U.S.C. 102(e) rejection over an issued U.S. patent which was a continuation-in-part (CIP). The parent application of the U.S. patent reference contained an example 2 which was not carried over to the CIP. The court held that the subject matter embodied in the canceled example 2 could not be relied on as of either parent or child filing date. Thus, the use of example 2 subject matter to reject the claims under pre-AIA 35 U.S.C. 102(e) was improper.).

Where a U.S. patent claims benefit to a provisional application, at least one claim of the patent must be supported by the disclosure of the relied upon provisional application in compliance with pre-AIA 35 U.S.C. 112, first paragraph, in order for the patent to be usable as prior art under pre-AIA 35 U.S.C. 102(e) as of the relied upon provisional application’s filing date. See MPEP § 2136.03, subsection III.

U.S. patents may be used as of their filing dates to show that the claimed subject matter is anticipated or obvious. Obviousness can be shown by combining other prior art with the U.S. patent reference in a 35 U.S.C. 103 rejection. Hazeltine Research v. Brenner, 382 U.S. 252, 147 USPQ 429 (1965). Similarly, certain U.S. application publications and certain international application publications may also be used as of their earliest effective U.S. filing dates (which will include certain international filing dates) to show that the claimed subject matter would have been anticipated or obvious.

See MPEP § 2146et seq. for additional information on rejections under 35 U.S.C. 103 and evidence of common ownership or a joint research agreement.

2136.03 Critical Reference Date [R-01.2024]

[Editor Note: This MPEP section is not applicable to applications subject to examination under the first inventor to file (FITF) provisions of the AIA as set forth in 35 U.S.C. 100 (note). See MPEP § 2159 et seq. to determine whether an application is subject to examination under the FITF provisions, and MPEP § 2150 et seq. for examination of applications subject to those provisions.]

Pre-AIA 35 U.S.C. 102(e) is explicitly limited to certain references “filed in the United States before the invention thereof by the applicant” (emphasis added). Foreign applications’ filing dates that are claimed (via 35 U.S.C. 119(a)–(d), (f) or 35 U.S.C. 365(a)) in applications, which have been published as U.S. or WIPO application publications or patented in the U.S., may not be used as pre-AIA 35 U.S.C. 102(e) dates for prior art purposes. This includes international filing dates claimed as foreign priority dates under 35 U.S.C. 365(a). Therefore, the foreign priority date of the reference under 35 U.S.C. 119(a)-(d), (f), and 35 U.S.C. 365(a) cannot be used to antedate the application filing date. In contrast, applicant may be able to overcome the pre-AIA 35 U.S.C. 102(e) rejection by proving the applicant is entitled to the 35 U.S.C. 119 priority date which is earlier than the reference’s U.S. filing date. In re Hilmer, 359 F.2d 859, 149 USPQ 480 (CCPA 1966) (Hilmer I) (Applicant filed an application with a right of priority to a German application. The examiner rejected the claims over a U.S. patent to Habicht based on its Swiss priority date. The U.S. filing date of Habicht was later than the application’s German priority date. The court held that the reference’s Swiss priority date could not be relied on in a pre-AIA 35 U.S.C. 102(e) rejection. Because the U.S. filing date of Habicht was later than the German priority date of the application, the rejection was reversed.). See MPEP § 216 for information on procedures to be followed in considering applicant's right of priority.

Note that certain international application (PCT) filings are considered to be “filings in the United States” for purposes of applying an application publication as prior art. See MPEP § 2120.01.

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

• (A) 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 U.S. filing date for prior art purposes under pre-AIA 35 U.S.C. 102(e). If such an international application properly claims benefit to an earlier-filed U.S. or international application, apply the reference under pre-AIA 35 U.S.C. 102(e) as of the earlier filing date, provided all the conditions of pre-AIA 35 U.S.C. 102(e) and 35 U.S.C. 120 or 365(c) are met. In addition, the subject matter relied upon in the rejection must be disclosed in the earlier-filed application in compliance with 35 U.S.C. 112(a) /pre-AIA 35 U.S.C. 112, first paragraph, in order to give that subject matter the benefit of the earlier filing date under pre-AIA 35 U.S.C. 102(e).

  If such an international application properly claims benefit to an earlier-filed U.S. provisional application, apply the reference under pre-AIA 35 U.S.C. 102(e) as of the earlier filing date, provided that the provisional application has proper support for the subject matter as required by 35 U.S.C. 119(e) and that at least one claim of the international application is supported by the written description of the relied upon provisional application in compliance with pre-AIA 35 U.S.C. 112, first paragraph or 35 U.S.C. 112(a). See MPEP § 2136.03, subsection III.

  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 U.S., and published in English under PCT Article 21(2)) for the earlier international filing date to be the U.S. filing date for prior art purposes under pre-AIA 35 U.S.C. 102(e).

• (B) 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 U.S. filing date. In this situation, do not apply the reference as of its international filing date, its date of completion of the 35 U.S.C. 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 pre-AIA 35 U.S.C. 102(a) or (b) as of its publication date, or pre-AIA 35 U.S.C. 102(e) as of any later U.S. filing date of an application that properly claimed the benefit of the international application (if applicable).

References based on international applications that were filed prior to November 29, 2000 are subject to the pre-AIPA version of 35 U.S.C. 102(e) (i.e., the version in force on November 28, 2000) as set forth below.

If an international application has an international filing date prior to November 29, 2000, the reference should be applied under the provisions of 35 U.S.C. 102 and 374 as in force on November 28, 2000 (prior to the AIPA amendments):

• (1) For U.S. patents, apply the reference under 35 U.S.C. 102(e) as in force on November 28, 2000 as of the earlier of the date of completion of the requirements of 35 U.S.C. 371(c)(1), (2) and (4) or the filing date of the later-filed U.S. application that claimed the benefit of the international application;
• (2) For U.S. application publications and WIPO publications directly resulting from international applications under PCT Article 21(2), never apply these references under 35 U.S.C. 102(e) as in force on November 28, 2000. These references may be applied as of their publication dates under pre-AIA 35 U.S.C. 102(a) or (b);
• (3) For U.S. application publications of applications that claim the benefit under 35 U.S.C. 120 or 365(c) of an international application filed prior to November 29, 2000, apply the reference under 35 U.S.C. 102(e) as in force on November 28, 2000 as of the actual filing date of the later-filed U.S. application that claimed the benefit of the international application.

Examiners should be aware that although a publication of, or a U.S. patent issued from, an international application may not be available as prior art under former 35 U.S.C. 102(e) as in force on November 28, 2000 or under pre-AIA 35 U.S.C. 102(e), the corresponding WIPO publication of an international application may have an earlier  pre-AIA 35 U.S.C. 102(a) or (b) date.

The critical reference date under pre-AIA 35 U.S.C. 102(e) of a U.S. patent, a U.S. patent application publication, as well as an international application publication having prior art effect under pre-AIA 35 U.S.C. 102(e), may be the filing date of a relied upon provisional application only if at least one of the claims in the reference patent, patent application publication, or international application publication is supported by the written description of the provisional application in compliance with pre-AIA 35 U.S.C. 112, first paragraph, or 35 U.S.C. 112(a). See Amgen Inc. v. Sanofi, 872 F.3d 1367, 1380, 124 USPQ2d 1354, 1363 (Fed. Cir. 2017); Dynamic Drinkware, LLC, v. National Graphics, Inc., 800 F.3d 1375, 116 USPQ2d 1045 (Fed. Cir. 2015). Dynamic Drinkware does not apply to AIA 35 U.S.C. 102(d). In other words, Dynamic Drinkware only applies to applications and patents subject to pre-AIA 35 U.S.C. 102. See MPEP § 2154.01(b) for information on determining the effectively filed date under AIA 35 U.S.C. 102(d). The provisional application must also describe, in compliance with pre-AIA 35 U.S.C. 112, first paragraph, or 35 U.S.C. 112(a), the subject matter relied upon in the reference patent or publication to make the rejection. See MPEP § 2136, examples 2, 4, and 7.

Note that international applications which (1) were filed prior to November 29, 2000, or (2) did not designate the U.S., 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 pre-AIA 35 U.S.C. 102(e).

For prior art purposes, a U.S. patent or patent application publication that claims the benefit of an earlier filing date under 35 U.S.C. 120 of a prior nonprovisional application (i.e., a continuation, divisional, or continuation-in-part application) would be accorded the earlier filing date as its prior art date under pre-AIA  35 U.S.C. 102(e), provided the earlier-filed application properly supports the subject matter relied upon in any rejection in compliance with 35 U.S.C. 112(a) or pre-AIA 35 U.S.C.  112, first paragraph. In other words, the subject matter used in the rejection must be disclosed in the earlier-filed application in compliance with 35 U.S.C. 112(a) or pre-AIA 35 U.S.C. 112, first paragraph, in order for that subject matter to be entitled to the earlier filing date under pre-AIA 35 U.S.C. 102(e).

See also MPEP § 2136, examples 2 and 5 to 9.

If a reference available under pre-AIA 35 U.S.C. 102(e) discloses, but does not claim the subject matter of the claims being examined or an obvious variant, the reference is not prior art under pre-AIA 35 U.S.C. 102(g). Furthermore, the reference does not qualify as “prior art” under 35 U.S.C. 102 as of a date earlier than its filing date based upon any prior inventive activity that is disclosed in the U.S. patent or U.S. patent application publication in the absence of evidence that the subject matter was actually reduced to practice in this country on an earlier date. See MPEP § 2138. When the cases are not in interference, the effective date of the reference as prior art is its filing date in the United States (which will include certain international filing dates), as stated in pre-AIA 35 U.S.C. 102(e). See MPEP §§ 2120.01 and2136. The date that the prior art subject matter was conceived or reduced to practice is of no importance when pre-AIA 35 U.S.C. 102(g) is not at issue. Sun Studs, Inc. v. ATA Equip. Leasing, Inc., 872 F.2d 978, 983, 10 USPQ2d 1338, 1342 (Fed. Cir. 1989) (The defendant sought to invalidate patents issued to Mason and Sohn assigned to Sun Studs. The earliest of these patents issued in June 1973. A U.S. patent to Mouat was found which issued in March 1976 and which disclosed the invention of Mason and Sohn. While the patent to Mouat issued after the Mason and Sohn patents, it was filed 7 months earlier than the earliest of the Mason and Sohn patents. Sun Studs submitted affidavits showing conception in 1969 and diligence to the constructive reduction to practice and therefore antedated the patent to Mouat. The defendant sought to show that Mouat conceived the invention in 1966. The court held that conception of the subject matter of the reference only becomes an issue when the claims of the conflicting patents cover inventions which are the same or obvious over one another. When pre-AIA 35 U.S.C. 102(e) applies but not pre-AIA 35 U.S.C. 102(g), the filing date of the prior art patent is the earliest date that can be used to reject or invalidate claims.).

2136.04 Different Inventive Entity; Meaning of “By Another” [R-10.2019]

[Editor Note: This MPEP section is not applicable to applications subject to examination under the first inventor to file (FITF) provisions of the AIA as set forth in 35 U.S.C. 100 (note). See MPEP § 2159 et seq. to determine whether an application is subject to examination under the FITF provisions, and MPEP § 2150 et seq. for examination of applications subject to those provisions.]

“Another” means other than applicants, In re Land, 368 F.2d 866, 151 USPQ 621 (CCPA 1966), in other words, a different inventive entity. The inventive entity is different if not all inventors are the same. The fact that the application and reference have one or more inventors in common is immaterial. Ex parte DesOrmeaux, 25 USPQ2d 2040 (Bd. Pat. App. & Inter. 1992) (The examiner made a pre-AIA 35 U.S.C. 102(e) rejection based on an issued U.S. patent to three inventors. The rejected application was a continuation-in-part of the issued parent with an extra inventor. The Board found that the patent was “by another” and thus could be used in a pre-AIA 35 U.S.C. 102(e)/103 rejection of the application.).

As stated by the House and Senate reports on the bills enacting section pre-AIA 35 U.S.C. 102(e) as part of the 1952 Patent Act, this subsection of 102 codifies the Milburn rule of Milburn v. Davis-Bournonville, 270 U.S. 390, 1926 C.D. 303, 344 O.G. 817 (1926). The Milburn rule authorized the use of a U.S. patent containing a disclosure of the invention as a reference against a later filed application as of the U.S. patent filing date. The existence of an earlier filed U.S. application containing the subject matter claimed in the application being examined indicates that applicant was not the first inventor. Therefore, a U.S. patent, a U.S. patent application publication or international application publication, by a different inventive entity, whether or not the application shares some inventors in common with the patent, is prima facie evidence that the invention was made “by another” as set forth in pre-AIA 35 U.S.C. 102(e). In re Mathews, 408 F.2d 1393, 161 USPQ 276 (CCPA 1969); In re Facius, 408 F.2d 1396, 161 USPQ 294 (CCPA 1969); Ex parte DesOrmeaux, 25 USPQ2d 2040 (Bd. Pat. App. & Inter. 1992). See MPEP § 2136.05et seq. for discussion of methods of overcoming pre-AIA 35 U.S.C. 102(e) rejections.

2136.05 Overcoming a Rejection Under Pre-AIA 35 U.S.C. 102(e) [R-10.2019]

[Editor Note: This MPEP section is not applicable to applications subject to examination under the first inventor to file (FITF) provisions of the AIA as set forth in 35 U.S.C. 100 (note). See MPEP § 2159 et seq. to determine whether an application is subject to examination under the FITF provisions, and MPEP § 2150 et seq. for examination of applications subject to those provisions. Information pertaining to overcoming pre-AIA 35 U.S.C. 102(e) rejections has been moved to MPEP § 2136.05(a) for affidavits or declarations under 37 CFR 1.131 and benefit or priority claims, and to MPEP § 2136.05(b) for affidavits or declarations under 37 CFR 1.132.]

In all applications, an applicant may overcome a pre-AIA 35 U.S.C. 102 rejection by persuasively arguing that the claims are patentably distinguishable from the prior art, or by amending the claims to patentably distinguish over the prior art. Additional ways available to overcome a rejection based on pre-AIA 35 U.S.C. 102 prior art depend on the applicable paragraph of pre-AIA 35 U.S.C. 102. See MPEP § 2132.01 for overcoming a rejection under pre-AIA 35 U.S.C. 102(a) and MPEP § 2133.02(a) for overcoming a rejection under pre-AIA 35 U.S.C. 102(b).
