Office Action

§102 §112 §DP
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 . Information Disclosure Statement As required by M.P.E.P. 609, the applicant’s submissions of the Information Disclosure Statement dated 3/12/2024 is acknowledged by the examiner and the cited references have been considered in the examination of the claims now pending. Examiner Notes The Examiner points out that while features of an apparatus may be recited either structurally or functionally, claims directed to an apparatus must be distinguished from the prior art in terms of structure rather than function. Limitations following "configured to," "adapted for," "designed to," "can be," and "capable of," or are statements of intended use are not positive limitations and thus are not given patentable weight. See MPEP 2111.04 and 2114. Specification The Abstract of the disclosure is objected to because of the terms “green-confusion absorbance region” and “yellow orange-confusion absorbance region”. A corrected abstract of the disclosure is required and must be presented on a separate sheet, apart from any other text. See MPEP § 608.01(b). 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 1-16 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. With respect to claims 1-16, the terms “green-confusion absorbance region” and “yellow orange-confusion absorbance region” are relative terms which render the claims indefinite. The terms “green-confusion” and “yellow orange-confusion” are not defined by the claim, the specification does not provide a standard for ascertaining the requisite degree, and one of ordinary skill in the art would not be reasonably apprised of the scope of the invention. The term “green-confusion” and “yellow orange-confusion” is a subjective term (MPEP 2173.05(b). Specifically, what constitutes “confusion” is entirely subjective to a practitioner of the invention and/or the subject themselves. What is confused or disordered? The metes and bounds are unclear since those of ordinary skill in the art would fail to understand what qualifies as being confused, and thus infringement becomes unclear (MPEP 2173.05; 2173). With respect to Claims 6, 14 and 15, the terms “predetermined ratio” in Claim 6, “predetermined ratio” in Claim 14, and “predetermined higher ratio” in Claim 15 are relative terms which render the claims indefinite. The term “predetermined ratio” and “predetermined higher ratio” are not defined by the claim, the specification does not provide a standard for ascertaining the requisite degree, and one of ordinary skill in the art would not be reasonably apprised of the scope of the invention. Thus, the adjustment of ratio absorbance relating to deficiency of vision in the claims have been rendered indefinite by the use of these terms. Double Patenting The nonstatutory double patenting rejection is based on a judicially created doctrine grounded in public policy (a policy reflected in the statute) so as to prevent the unjustified or improper timewise extension of the “right to exclude” granted by a patent and to prevent possible harassment by multiple assignees. A nonstatutory double patenting rejection is appropriate where the conflicting claims are not identical, but at least one examined application claim is not patentably distinct from the reference claim(s) because the examined application claim is either anticipated by, or would have been obvious over, the reference claim(s). See, e.g., In re Berg, 140 F.3d 1428, 46 USPQ2d 1226 (Fed. Cir. 1998); In re Goodman, 11 F.3d 1046, 29 USPQ2d 2010 (Fed. Cir. 1993); In re Longi, 759 F.2d 887, 225 USPQ 645 (Fed. Cir. 1985); In re Van Ornum, 686 F.2d 937, 214 USPQ 761 (CCPA 1982); In re Vogel, 422 F.2d 438, 164 USPQ 619 (CCPA 1970); In re Thorington, 418 F.2d 528, 163 USPQ 644 (CCPA 1969). A timely filed terminal disclaimer in compliance with 37 CFR 1.321(c) or 1.321(d) may be used to overcome an actual or provisional rejection based on nonstatutory double patenting provided the reference application or patent either is shown to be commonly owned with the examined application, or claims an invention made as a result of activities undertaken within the scope of a joint research agreement. See MPEP § 717.02 for applications subject to examination under the first inventor to file provisions of the AIA as explained in MPEP § 2159. See MPEP §§ 706.02(l)(1) - 706.02(l)(3) for applications not subject to examination under the first inventor to file provisions of the AIA . A terminal disclaimer must be signed in compliance with 37 CFR 1.321(b). The USPTO Internet website contains terminal disclaimer forms which may be used. Please visit www.uspto.gov/patent/patents-forms. The filing date of the application in which the form is filed determines what form (e.g., PTO/SB/25, PTO/SB/26, PTO/AIA /25, or PTO/AIA /26) should be used. A web-based eTerminal Disclaimer may be filled out completely online using web-screens. An eTerminal Disclaimer that meets all requirements is auto-processed and approved immediately upon submission. For more information about eTerminal Disclaimers, refer to www.uspto.gov/patents/process/file/efs/guidance/eTD-info-I.jsp. Claims 1-16 are provisionally rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1-16 of copending Application No. 18/601,938. The device of the copending application 18/601,938 discloses the same invention except for disclosing an “orange-confusion absorbance region”. It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to choose a similar chroma enhancement optical lens device as taught by the current copending application because it is a well-established proposition that the selection of a known material based on its suitability for its intended use is within the skill of one of ordinary skill in the art Sinclair & Carroll Co. v.Interchemical Corp., 325 U.S. 327, 65 USPQ 297 (1945) See also In reLeshin, 277 F.2d 197, 125 USPQ 416 (CCPA 1960). MPEP §2144.07. Furthermore, although the claims at issue are not identical, they are not patentably distinct from each other. Claims 1-16 are provisionally rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1-16 of copending Application No. 18/600,575. The device of the copending application 18/600,575 discloses the same invention except for disclosing a “yellow-green confusion absorbance region”. It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to choose a similar chroma enhancement optical lens device as taught by the current copending application because it is a well-established proposition that the selection of a known material based on its suitability for its intended use is within the skill of one of ordinary skill in the art Sinclair & Carroll Co. v.Interchemical Corp., 325 U.S. 327, 65 USPQ 297 (1945) See also In reLeshin, 277 F.2d 197, 125 USPQ 416 (CCPA 1960). MPEP §2144.07. Furthermore, although the claims at issue are not identical, they are not patentably distinct from each other. This is a provisional nonstatutory double patenting rejection because the patentably indistinct claims have not in fact been patented. Claim Rejections - 35 USC § 102 In the event the determination of the status of the application as subject to AIA 35 U.S.C. 102 and 103 (or as subject to pre-AIA 35 U.S.C. 102 and 103) is incorrect, any correction of the statutory basis (i.e., changing from AIA to pre-AIA ) for the rejection will not be considered a new ground of rejection if the prior art relied upon, and the rationale supporting the rejection, would be the same under either status. 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. Claim(s) 1-16 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by McCabe (20230176402).
