Office Action

§112
DETAILED ACTION Claim Rejections - 35 USC § 112 The following is a quotation of 35 U.S.C. 112(b): (b) CONCLUSION.—The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the inventor or a joint inventor regards as the invention. The following is a quotation of 35 U.S.C. 112 (pre-AIA ), second paragraph: The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the applicant regards as his invention. Claims 1 and 3-14 are rejected under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), second paragraph, as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor (or for applications subject to pre-AIA 35 U.S.C. 112, the applicant), regards as the invention. As discussed in the interview of 08 April 2026, extensive amendments to the claims are necessary in order to overcome the 112 rejection. In that interview, these issues of indefiniteness were thoroughly discussed with respect to this same set of claims, but solutions thereto have not been incorporated into the current claims. Because these instances were discussed in that interview and with respect to these claims, they are not detailed in this Office action. Allowable Subject Matter There is currently no rejection in view of the prior art; however, patentability cannot be fully determined until the 112 rejections are overcome.
