Office Action

§103 §DOUBLEPATENT
DETAILED ACTION It would be of great assistance to the Office if all incoming papers pertaining to a filed application carried the following items: 1. Application number (checked for accuracy, including series code and serial no.). 2. Group art unit number (copied from most recent Office communication). 3. Filing date. 4. Name of the examiner who prepared the most recent Office action. 5. Title of invention. 6. Confirmation number (See MPEP § 503). 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 . Claim Objections Claim 1 is objected to because of the following informalities: a period is missing at the end of the claim. 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 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. Claims 1 – 24 are rejected on the ground of nonstatutory double patenting as being unpatentable over claim 1 of U.S. Patent No. 12,431,975 in view of Fratti et al.

As to claim 11 (dependent on 1), Cha discloses the pixel device, wherein the pixel device or the display apparatus formed from the pixel device further comprises a plurality of optical front end circuitry elements (OLED elements used for transmission [0038 – 0040] are interpreted as the optical front end circuitry elements). As to claim 13 (dependent on 1), Cha discloses the pixel device, wherein the red, green and blue elements are configured to transmit modulated light comprising an uplink data signal to a further OWC device (transmission for visible light communication with another device [0043]). As to claim 14 (dependent on 1), Cha in view of Fratti discloses the pixel device, further comprising additional circuitry, wherein the additional circuitry comprises at least one of: a driver, a contact, a capacitance line, a scan line, a data line, a switching TFT, a supply line or a capacitor (Fratti, circuitry of fig. 1, such as scan line and data line). As to claim 18 (dependent on 1), Cha in view of Fratti discloses the pixel device, wherein the pixel structure comprises an aperture comprising said red, green and blue display elements (Fratti, matrix of RGB picture elements [0017]). As to claim 19 (dependent on 1), Cha in view of Fratti discloses the pixel device, wherein the formed display comprises an array of elements comprising the at least one light receiving element and the plurality of display elements of the pixel device, wherein the array of elements are configured to display an image to a user and configured to receive modulated light (Fratti, sensor and transmitter array as shown in fig. 2). As to claim 20 (dependent on 1), Cha discloses a display apparatus comprising a display comprising a plurality of pixel devices of claim 1 and an optical wireless communication apparatus (the monitor of fig. 1). As to claim 21 (dependent on 20), Cha discloses the electronic device comprising the display apparatus of claim 20 (laptop [0033]). As to claim 22 (dependent on 21), Cha discloses the electronic device, wherein the electronic device comprises at least one of: mobile phone, tablet, laptop, a computer, an aviation cockpit display, a television, a financial transaction terminal, an industrial control panel, a point of sale device, a smart banner, or a monitor (laptop [0033]). As to claim 23 (dependent on 1), Cha discloses a method of operating a pixel device according to claim 1, further comprising at least one of transmitting modulated light from the display apparatus to a further OWC device or receiving modulated light from the further OWC device by the display apparatus, thereby providing optical wireless communication with the further OWC device using the modulated light [0038 – 0043]. As to claim 24 (dependent on 20), Cha discloses a method of operating a display apparatus according to claim 20, further comprising at least one of transmitting modulated light from the display apparatus to a further OWC device or receiving modulated light from the further OWC device by the display apparatus, thereby providing optical wireless communication with the further OWC device using the modulated light [0038 – 0043].
