Office Action

§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 12/06/2024 and 11/24/2025 is acknowledged by the examiner and the cited references have been considered in the examination of the claims now pending. Specification The abstract of the disclosure is objected to because it uses legalese - i.e. it is an almost verbatim copy of claim 1 and 10. Correction is required. See MPEP § 608.01(b). Applicant is reminded of the proper language and format for an abstract of the disclosure. The abstract should be in narrative form and generally limited to a single paragraph on a separate sheet within the range of 50 to 150 words. The form and legal phraseology often used in patent claims, such as "means" and "said," should be avoided. The abstract should describe the disclosure sufficiently to assist readers in deciding whether there is a need for consulting the full patent text for details. The language should be clear and concise and should not repeat information given in the title. It should avoid using phrases which can be implied, such as, "The disclosure concerns," "The disclosure defined by this invention," "The disclosure describes," etc. Double Patenting 4. 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 claims at issue 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); and 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 a nonstatutory double patenting ground provided the reference application or patent either is shown to be commonly owned with this 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/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 http://www.uspto.gov/patents/process/file/efs/guidance/eTD-info-I.jsp. 5. Claims 1-20 are rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1-20 of U.S. Patent Application No. 18/972179. Although the claims at issue are not identical, they are not patentably distinct from each other because instant claim 1 and instant claim 10 recites similar subject matter as claim 1 and claim 10 of co-pending application ‘179. Although co-pending application ‘179 does not explicitly disclose both a width of the first groove and a width of the second groove are a, and a distance between orthographic projections of any adjacent first groove and second groove onto the plane of the electrochromic layer is b, wherein a sum of the a and the b satisfies a following relationship: 0<a+b≤100mm, substantially identical materials treated in a substantially identical manner are expected to have substantially identical properties. In the present case the electrochromic film is carried out using material and process conditions which are substantially identical to those disclosed by applicants. Therefore the electrochromic film discussed above would be expected to meet the claimed width of the first groove and a width of the second groove are a, and a distance between orthographic projections of any adjacent first groove and second groove onto the plane of the electrochromic layer is b, wherein a sum of the a and the b satisfies a following relationship: 0<a+b≤100mm. All of the remaining instant claims recite similar subject matter as claims 2-9 and 11-20 of co-pending application '179. Conclusion The prior art made of record and not relied upon is considered pertinent to applicant's disclosure. Zhong (20230021421), Friedman (20220019114), and Seo (20150077361) are examples of an electrochromic structure assembly that can be darkened or lightened electrically.
