Office Action

§103 §112
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 . 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 1-8 and 10 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. There is no “description support” in the original specification for the recitation of “about 1 %” by weight of a water-retaining gel (as opposed to 1% by weight) or for jaggery in an amount of “about 2-10%” by weight (as opposed to 2-10% by weight). Page 6, lines 13-17 of the original specification and original claim 2 disclose “1% by weight of water-retaining gel” and “2-10% of jaggery”. Claim Rejections - 35 USC § 103 The following is a quotation of 35 U.S.C. 103 which forms the basis for all obviousness rejections set forth in this Office action: A patent for a claimed invention may not be obtained, notwithstanding that the claimed invention is not identically disclosed as set forth in section 102, if the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to which the claimed invention pertains. Patentability shall not be negated by the manner in which the invention was made. Claim 9 is rejected under 35 U.S.C. 103 as being unpatentable over Paikray (US 2012/0031157) in view of CN 111492742 A, for the reasons given in the last Office Action. Applicant’s argument, that Paikray does not teach, disclose or suggest the use of liquid biodegradable waste as a raw material or feedstock for microbial biodecomposition, is not convincing., since Paikaray discloses in claim 13 that the carrier can be in the form of a liquid. Applicant’s argument, that Paikray is entirely silent with respect to liquid waste decomposition and therefore fails to disclose or suggest the core inventive concept recited in applicant’s claims, is not convincing, since Paikray discloses in Paragraph [0063] that the fermentation material can be farmyard manure, which is typically liquid or semi-liquid. Applicant’s argument, that the gel used in CN 111492742 A functions as a structural coating around solid aggregates and is not used as part of a liquid biodecomposition system, is not convincing, since claim 9 does not recite a water-retaining gel. This application apparently discloses allowable subject matter. Applicant's amendment necessitated the new ground(s) of rejection presented in this Office action. Accordingly, THIS ACTION IS MADE FINAL. See MPEP § 706.07(a). Applicant is reminded of the extension of time policy as set forth in 37 CFR 1.136(a). A shortened statutory period for reply to this final action is set to expire THREE MONTHS from the mailing date of this action. In the event a first reply is filed within TWO MONTHS of the mailing date of this final action and the advisory action is not mailed until after the end of the THREE-MONTH shortened statutory period, then the shortened statutory period will expire on the date the advisory action is mailed, and any nonprovisional extension fee (37 CFR 1.17(a)) pursuant to 37 CFR 1.136(a) will be calculated from the mailing date of the advisory action. In no event, however, will the statutory period for reply expire later than SIX MONTHS from the mailing date of this final action.
