Appeals from United States Patent and Trademark Office rejections of patent applications are a critical component of patent prosecution practice. But, the rule governing the all-important question of when a rejection is ripe for appeal is not the model of clarity that practitioners might expect (See 35 U.S.C. §134). Under 37 CFR §41.31(a)(1) (emphasis added), “[e]very applicant, any of whose claims has been twice rejected, may appeal from the decision of the examiner to the [Patent Trial and Appeal] Board (PTAB) by filing a notice of appeal.” The wording of 37 CFR §41.31(a)(1), however, is unclear as to whether “twice rejected” requires two rejections of a claim having exactly the same wording. In other words, would amending a claim after an initial rejection prevent an applicant from filing a notice of appeal after receiving a subsequent rejection of the amended claim? As will be discussed below, the answer to that question is no. There is no “exactness requirement” in the “twice rejected” rule (See MPEP §1204).
The controlling case on the “twice rejected” rule is Ex Parte Lemoine, 46 USPQ2d 1420 (Bd. Pat. App. & Inter. 1994). In Ex Parte Lemoine, an applicant received an Office Action, finally rejecting all of the pending claims in an application under 35 U.S.C. §112, second paragraph, and 35 U.S.C. §103. The applicant responded by filing a continuation application, and made some preliminary amendments to the claims, which included the addition of five new claims. The applicant then received a non-final rejection of the continuation application, which essentially repeated the previous grounds of rejection made in the parent application. The applicant then filed a notice of appeal. In response, the Examiner held the application to be abandoned, stating that the notice of appeal was improper at that particular stage of prosecution (Ex Parte Lemoine, 46 USPQ2d at 1420-22). The appeal was eventually forwarded to the Board of Patent Appeals and Interferences (now the PTAB).
Upon review of the appeal, the Board decided that the applicant had a right to appeal the non-final rejection of the claims. Specifically, the Board stated that the term “claims” as used in 35 U.S.C. §134 is “used in a more general sense to refer to claims ‘for a patent’ … the word is synonymous with a request or demand for a patent” (Ex Parte Lemoine, 46 USPQ2d at 1423 (emphasis added)). The Board further stated that “[u]nder our interpretation, so long as the applicant has twice been denied a patent, an appeal may be filed” (Ex Parte Lemoine, 46 USPQ2d 1423).
