Office Action

§103 §112
DETAILED ACTION 1. The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA . 2. Claim 1 is pending. Claim Rejections - 35 USC § 112 3. The following is a quotation of 35 U.S.C. 112(b): (b) CONCLUSION.—The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the inventor or a joint inventor regards as the invention. The following is a quotation of 35 U.S.C. 112 (pre-AIA ), second paragraph: The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the applicant regards as his invention. 4. Claim 1 is rejected under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), second paragraph, as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor (or for applications subject to pre-AIA 35 U.S.C. 112, the applicant), regards as the invention. Claim 1 recites the limitation "at least one of the domains of temporal synchronization" (emphasis added) in step “d)”. There is insufficient antecedent basis for this limitation in the claim. Claim Rejections - 35 USC § 103 5. 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. Ashley 6. The following is a quotation of 35 U.S.C. 103 which forms the basis for all obviousness rejections set forth in this Office action: A patent for a claimed invention may not be obtained, notwithstanding that the claimed invention is not identically disclosed as set forth in section 102, if the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to which the claimed invention pertains. Patentability shall not be negated by the manner in which the invention was made. 7. Claim 1 is rejected under 35 U.S.C. 103 as being unpatentable over Ashley (US PG Pub. 2014/0168277) in view of Toren (US PG Pub. 204/0002327). As regarding claim 1, Ashley discloses A system for securely casting customized content within an environment, comprising: a display mechanism for rendering a plurality of windows, said display mechanism being configurable as either a single display or multiple displays [para. 214; surfaces rendering a plurality of displays]; a synchronization controller configured to manage temporal and contextual synchronization between the plurality of windows [para. 8 and 214; synchronizing content across plurality of display surfaces]; a user profile database storing user preferences and context matrices [para. 77, 139, 171, 189; retrieving user preferences from a storage]; wherein the synchronization controller is configured to: a) retrieve a current context from the plurality of windows [para. 185-194; retrieving current context for plurality of screens], the current context including but not limited to parameters such as type of activity, time of day [para. 185 and 191], and current user settings [para. 190]; b) access a predicted context from the user profile database, the predicted context being based on the current context and historical user interactions [para. 121; accessing history engaging of the viewer]; c) display a multi-window configuration based on the predicted context [adapting the presentation of content based on the history engaging of the viewer]; Ashley does not explicitly disclose a security manager for providing secure data transmission and authentication between the plurality of windows; and d) perform secure data transmission and authentication to synchronize the plurality of windows in at least one of the domains of temporal synchronization and context synchronization. However, Toren discloses it [abstract, para. 22, 24 and 29-34; performing authentication before synchronizing a plurality of displays based on the proximity of the displays]. It would have been obvious to one of ordinary skill in the art at the time the effective filing of the invention to modify Ashley’s system to further comprise the missing claim features, as disclosed by Toren, so as to ensure only authorized users allowed to synchronize or adjust a plurality of displays [Toren para. 22 and 30].
