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 . Examiner Notes Examiner cites particular columns and line numbers in the references as applied to the claims below for the convenience of the applicant. Although the specified citations are representative of the teachings in the art and are applied to the specific limitations within the individual claim, other passages and figures may apply as well. It is respectfully requested that, in preparing responses, the applicant fully consider the references in entirety as potentially teaching all or part of the claimed invention, as well as the context of the passage as taught by the prior art or disclosed by the examiner. Specification The disclosure is objected to because of the following informalities: Paragraph [0001], line 2, --now US Patent No. 12,124,658 issued on October 22-2022,-- should be inserted after “filed 22 November 2022,”. Appropriate correction is required. Claim Objections Claims 22-31, 33-38 and 40-44 are objected to because of the following informalities: Line 1, “A” should be changed to --The--. Appropriate correction is required. 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 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 21-44 are rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1-5, 8, 12-17 and 20 of U.S. Patent No. 12,124,658. Although the claims at issue are not identical, they are not patentably distinct from each other because they can be interpreted to describe substantially identical, very similar claimed limitations, or being obvious which are shown below: Instant application 18/826,836 U.S. Patent No. 12,124,658 Claim 21: A system for receiving input to control an apparatus, the system comprising: a display for displaying video content based on display signals; one or more capacitive sensors which are sensitive to disturbances in their electric fields caused by a human body part in proximity to a user-facing side of the display; a controller connected to receive one or more capacitive sensor signals from the one or more capacitive sensors to generate a control signal based on the one or more capacitive sensor signals, the controller connectable to the apparatus to provide the control signal as an input to a control system of the apparatus and to thereby cause the control system of the apparatus to operate the apparatus based on the control signal; wherein at least one electrode of each of the one or more capacitive sensors is located on a user-facing side of the display, the at least one electrode of each of the one or more capacitive sensors fabricated from transparent conductive material, so that the human user can see the display through the at least one electrode of each of the one or more capacitive sensors.
