Office Action

§112
DETAILED ACTION Notice of Pre-AIA or AIA Status The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA . Continued Examination Under 37 CFR 1.114 A request for continued examination under 37 CFR 1.114, including the fee set forth in 37 CFR 1.17(e), was filed in this application after final rejection. Since this application is eligible for continued examination under 37 CFR 1.114, and the fee set forth in 37 CFR 1.17(e) has been timely paid, the finality of the previous Office action has been withdrawn pursuant to 37 CFR 1.114. Applicant's submission filed on April 30, 2026 has been entered. Claims 6-9 are new. Claims 1-9 are pending examination. Claim Rejections - 35 USC § 112 The following is a quotation of the first paragraph of 35 U.S.C. 112(a): (a) IN GENERAL.—The specification shall contain a written description of the invention, and of the manner and process of making and using it, in such full, clear, concise, and exact terms as to enable any person skilled in the art to which it pertains, or with which it is most nearly connected, to make and use the same, and shall set forth the best mode contemplated by the inventor or joint inventor of carrying out the invention. The following is a quotation of the first paragraph of pre-AIA 35 U.S.C. 112: The specification shall contain a written description of the invention, and of the manner and process of making and using it, in such full, clear, concise, and exact terms as to enable any person skilled in the art to which it pertains, or with which it is most nearly connected, to make and use the same, and shall set forth the best mode contemplated by the inventor of carrying out his invention. Claims 1-9 are rejected under 35 U.S.C. 112(a) or 35 U.S.C. 112 (pre-AIA ), first paragraph, as failing to comply with the written description requirement. The claim(s) contains subject matter which was not described in the specification in such a way as to reasonably convey to one skilled in the relevant art that the inventor or a joint inventor, or for applications subject to pre-AIA 35 U.S.C. 112, the inventor(s), at the time the application was filed, had possession of the claimed invention. Claim 1 has been amended to require “wherein the liquid egg-substitute composition is free of a crosslinking agent at a level effective to crosslink a hydrocolloid”. Applicant finds that paragraphs [0011] and [0020] of the specification as originally filed provide support for the new limitation. Paragraph [0011] disclose a liquid egg-substitute composition. Paragraph [0011] does not recite the inclusion or exclusion of a crosslinking agent. Paragraph [0020] disclose a method of producing a liquid egg-substitute composition. Paragraph [0020] does not recite the inclusion or exclusion of a crosslinking agent. Any negative limitation or exclusionary proviso must have basis in the original disclosure. If alternative elements are positively recited in the specification they may be explicitly excluded in the claims. The mere absence of a positive recitation is not basis for exclusion (MPEP §2173.05(i)). Response to Arguments Applicant’s arguments with respect to claims 1-5 have been considered but are moot because the new ground of rejection does not rely on any reference applied in the prior rejection of record for any teaching or matter specifically challenged in the argument. Applicant is directed to the rejection of claim 1 under 35 U.S.C. 112(a) as failing to comply with the written description requirement. Conclusion Any inquiry concerning this communication or earlier communications from the examiner should be directed to ELIZABETH A GWARTNEY whose telephone number is (571)270-3874.
