Office Action

§DOUBLEPATENT
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 . Priority This application discloses and claims only subject matter disclosed in prior Application No. 18484320, filed 10/10/2023, and names the inventor or at least one joint inventor named in the prior application. Accordingly, this application may constitute a continuation or divisional. Should applicant desire to claim the benefit of the filing date of the prior application, attention is directed to 35 U.S.C. 120, 37 CFR 1.78, and MPEP § 211 et seq. The presentation of a benefit claim may result in an additional fee under 37 CFR 1.17(w)(1) or (2) being required, if the earliest filing date for which benefit is claimed under 35 U.S.C. 120, 121, 365(c), or 386(c) and 1.78(d) in the application is more than six years before the actual filing date of the application. 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 § 2146 et seq. 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 filing of a terminal disclaimer by itself is not a complete reply to a nonstatutory double patenting (NSDP) rejection. A complete reply requires that the terminal disclaimer be accompanied by a reply requesting reconsideration of the prior Office action. Even where the NSDP rejection is provisional the reply must be complete. See MPEP § 804, subsection I.B.1. For a reply to a non-final Office action, see 37 CFR 1.111(a). For a reply to final Office action, see 37 CFR 1.113(c). A request for reconsideration while not provided for in 37 CFR 1.113(c) may be filed after final for consideration. See MPEP §§ 706.07(e) and 714.13. The USPTO Internet website contains terminal disclaimer forms which may be used. Please visit www.uspto.gov/patent/patents-forms. The actual 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/apply/applying-online/eterminal-disclaimer. Claim 1 is rejected on the ground of nonstatutory double patenting as being unpatentable over claim 1 of U.S. Patent No. 12399591. Although the claims at issue are not identical, they are not patentably distinct from each other because both applications recite substantially similar claim limitations. 19/223743 U.S. Patent No. 12399591 An electronic device configured to gather touch input from a finger, comprising: a display having a display cover layer with a surface, wherein the surface has a surface normal; and an optical touch sensor comprising: light sources configured to emit light into the display cover layer; light detectors that are configured to detect reflections of the light when the surface is contacted by the finger; and angular filters, wherein each angular filter blocks light at a first subset of incident angles from reaching a respective light detector of the light detectors and passes light at a second subset of incident angles to the respective light detector and wherein the first subset of incident angles includes light that is parallel to the surface normal. An electronic device comprising: a display having a display cover layer with a surface; and an optical touch sensor comprising: at least one light source that is configured to emit light into the display cover layer; and at least one light detector, wherein total internal reflection is locally defeated to scatter the emitted light towards the at least one light detector when the surface is contacted by a finger and wherein total internal reflection is not locally defeated when the surface is exposed to water. Allowable Subject Matter Claims 1, 12, 17 would be allowable if rewritten or amended to overcome the double patenting rejection(s), set forth in this Office action. The following is an examiner’s statement of reasons for allowance: Regarding claims 1, 12, 17: The closest prior art is Wassvik et al. (U.S. Patent Publication 20160026337 A1). However, the prior art does not teach or suggest either singularly or in combination the specifically claimed, “angular filters, wherein each angular filter blocks light at a first subset of incident angles from reaching a respective light detector of the light detectors and passes light at a second subset of incident angles to the respective light detector and wherein the first subset of incident angles includes light that is parallel to the surface normal.", in the context of the rest of the claimed limitations. Any comments considered necessary by applicant must be submitted no later than the payment of the issue fee and, to avoid processing delays, should preferably accompany the issue fee. Such submissions should be clearly labeled “Comments on Statement of Reasons for Allowance.” Conclusion The prior art made of record and not relied upon is considered pertinent to applicant's disclosure. US 20150002473 A1 discloses optical touch sensor on abstract. US 20170316248 A1 discloses light source on Fig. 12. US 20080179507 A1 discloses light sources on Fig. 2. US 11353994 B1 discloses angular filter on abstract.
