(103) Any Application Filed With Instructions to Cancel All of the Claims in the Application is Not Entitled to a Filing Date In view of the Federal Circuit decision in Baxter Int'l. Inc. v. McGaw Inc., 149 F.3d 1321, 47 USPQ2d 1225 (Fed. Cir. 1998), decided June 30, 1998, the PTO is revising its treatment of applications deposited with instructions contained in preliminary amendments or transmittal letters to cancel all of the claims in the application. MPEP 711.01 and 714.19 currently indicate that an amendment canceling all of the claims and presenting no new or substitute claims is ordinarily denied entry. The MPEP does not, however, differentiate between amendments submitted with the filing of an application and all other amendments. Baxter involved a patent granted on an application filed as a divisional application under former 37 C.F.R. 1.60 with instructions to cancel all of the claims in the specification without presenting any new claims. The PTO accorded the application a filing date (as of the date of receipt of the copy of the specification and drawings) and sent applicant a notice that the instructions were improper because they would leave the application without claims for examination. In response to the notice, applicant subsequently filed an amendment adding replacement claims. The court held that the (divisional) application was not entitled to the original filing date because the requirements of 35 U.S.C. 112, second paragraph, had not been met, i.e., the application was effectively filed without a claim. The court concluded that the earliest filing date that could be accorded was the date a claim was filed (which was the date the amendment was filed in response to the notice from the PTO). The court also stated that the lack of a claim was a statutory defect which the PTO could not waive. As a result of Baxter, the PTO will no longer accord a filing date to any application (original, continuation, divisional or continuation-in-part) submitted under 37 C.F.R. 1.53(b) or Continued Prosecution Application (CPA) (continuation or divisional) submitted under 37 C.F.R. 1.53(d) where the application is accompanied by a preliminary amendment which cancels all claims and fails to simultaneously submit any new claims. MPEP 711.01 and 714.19 will be revised to state that an amendment filed after the filing date of an application which cancels all of the claims and presents no substitute claim or claims is ordinarily denied entry. In addition, MPEP 601.01 (e) will be revised to call attention to Baxter. When filing an application under 37 C.F.R. 1.53(b) or CPA request under 37 C.F.R. 1.53(d), applicants and practitioners are reminded to carefully review the application papers, including any preliminary amendments to be filed with the application, to ensure that the application will contain at least one claim after the preliminary amendments are entered.
