Office Action

§DP
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 . DETAILED ACTION The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA . 1. This action is responsive to communications: Application filed on March 8, 2024, and Drawings filed on March 8, 2024. 2. Claims 1–20 are pending in this case. Claim 1, 8, 15 are independent claims. 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 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. Allowable Subject Matter Claims 20 is objected to as being dependent upon a rejected base claim, but would be allowable if rewritten in independent form including all of the limitations of the base claim and any intervening claims. Double Patenting 1. 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 1-19 are rejected on the ground of nonstatutory double patenting as being unpatentable over and anticipated by claims 1, 2, 3, 4, 5, 6, 7, 8, 12, 14, 15, 16, 17 of U.S. Patent 11934637B2. Although the claims at issue are not identical, they are not patentably distinct from each other because claims 1-19 under examination are anticipated, respectively, by claims 1, 2, 3, 4, 5, 6, 7, 8, 12, 14, 15, 16, 17 of the reference patent. Every limitation in the application under examination claims is recited in the conflicting reference patent claims, and the differences between the claims are highlighted below by bolding all limitations that differ, italicizing additional limitations, and underlining limitations that will be addressed below.

Claim 1-19 would be allowable if rewritten or amended to overcome the rejection(s) under double patenting. Pertinent Arts The prior art made of record and not relied upon is considered pertinent to applicant's disclosure. Tse et al, Pub. No.: 20160142471 A1, Systems, devices, and methods are provided for providing interactive collaboration among computing devices. In some aspects, an interactive display device can display a graphical interface corresponding to a shared workspace. The interactive display device can communicate with multiple computing devices, each computing device associated with a virtual position. A processing device of the interactive display device can update the graphical interface to depict the respective virtual positions associated with each computing device. For each computing device, the interactive display device can also provide access to a respective portion of the shared workspace indicated by the respective virtual position associated with the computing devices. The processing device can trigger an action on the interactive display device based on determining that a subset of computing devices have performed a threshold activity. Parker, Pub. No.: US 20160085381 A1: Several methods are described herein to allow users to manage and synchronize views in a multi-user application with canvas (infinite or otherwise) and limited or unlimited zoom. Without these synchronization methods, coordinating views is very difficult, and may lead to chaos as one or more of the users gets lost on the canvas. A “View Sync” method provides for many-to-one synchronization, where many users are automatically synchronized with one user. A “Sync View” method provides for one-to-one synchronization, where one user is synchronized to another user's view. Preferably, off-screen “activity indicators” also are used within the viewport to provide visual cues regarding where other users are drawing or creating content on the canvas. Tapping on an activity indicator preferably performs one-time Sync View with the selected other user. Laukkanen, Pub. No.: 20140282229 A1: A computer program product for providing a graphical user interface for displaying of and enabling cooperative use of resources on a display of a computing device includes computer readable code means, the computer readable code means when executed by a processor device, being configured to provide an environment, the environment being configured to represent the resources on the display of the computing device, provide a first viewport to at least a portion of the environment on the display of the computing device, enable a resource to be added to the environment and be viewed within the first viewport and enable the resource to be acted upon within the first viewport.
