Office Action

§102 §103
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 . DETAILED ACTION Although applicant had requested to USPTO to retrieve the Foreign Priority Document on May 7, 2023, somehow the PTO file does not show the Foreign Priority Document. Note that it would be applicant’s ultimate responsibility to make sure that the PTO file has the Foreign Priority Document. Claim Rejections - 35 USC § 102 and 35 USC § 103 The following is a quotation of the appropriate paragraphs of 35 U.S.C. 102 that form the basis for the rejections under this section made in this Office action: A person shall be entitled to a patent unless – (a)(1) the claimed invention was patented, described in a printed publication, or in public use, on sale, or otherwise available to the public before the effective filing date of the claimed invention. 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. Claims 1-3, 8-13 and 15-17 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Machine translated JP 2005506389 A (March 3, 2005). Rejection is maintained for reason of the record. RESPONSE TO ARGUMENTS Applicant asserts that JP refers to solids content of < 25% in the composition fed into the extruder (Para. [0025]), the para. [0025] teaches away from “more than 25% solids” which would include 25% further evidenced by abstract contrary to assertions. Applicant asserts that JP teaches “steam explosion” which would be different the instant process, the examiner interprets the recited “adjusting a pressure (12) acting on the mixture to at least the vapor pressure of water at a first temperature” of claim 1 would encompass the “steam explosion” taught by JP since the recited “to at least the vapor pressure of water” would be a minimum condition and scope of “to at least the vapor pressure of water at a first temperature” would encompass beyond the minimum condition such as the asserted sufficiently high temperature and pressure taught by JP contrary to the assertion that the instant pressure is such that the water in the mixture remains liquid. In other words, there is no limitation in the instant claims that the instant pressure must yield the water in the mixture being the liquid. Applicant asserts a low residual moisture content of 10-20% for example, but % residual moisture content is not the claimed limitation. Claims 4-7 are rejected under 35 U.S.C. 103 as being unpatentable over Machine translated JP 2005506389 A (March 3, 2005) as applied to claims 1-3, 8-13 and 15-17 above, and further in view of Larsen (US 5,502,179). Rejection is maintained for reason of the record. RESPONSE TO ARGUMENTS Responses to arguments as to JP are discussed above. JP teaches utilization of various substances (additives) such as various esters which are known plasticizers taught in line 21 at col. 5 of US 5,502.179. Claim 14 is rejected under 35 U.S.C. 103 as being unpatentable over Machine translated JP 2005506389 A (March 3, 2005) as applied to claims 1-3, 8-13 and 15-17 above, and further in view of Machine translated JP 2001506692 A (May 22, 2001). Rejection is maintained for reason of the record. RESPONSE TO ARGUMENTS Responses to arguments as to JP are discussed above and applicant failed to point out any error of the Examiner citing JP 2001506692 A teaching the art well injection molding used for obtaining the capsules. THIS ACTION IS MADE FINAL. Applicant is reminded of the extension of time policy as set forth in 37 CFR 1.136(a).
