Office Action

§103
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 . Status of Claims The rejections of claims 1-4, 8-12, 16, and 17 under 35 U.S.C. 103 have been withdrawn in light of the Applicants’ amendments. Claims 1, 5, 6, 7, 9, 13, 14, 15, and 17-20 have been amended. Thus, claims 1-20 are presented for examination. Allowable Subject Matter Claims 5, 6, 7, 13, 14, 15, 18, 19, and 20 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. The following is a statement of reasons for the indication of allowable subject matter: The most similar art of record, Vega et al. [U.S. Patent Publication 2017/0134898], discloses a tracking device location manager in a tracking system used for tracking the location of a device (paragraphs 0032 and 0034 as well as figure 2, item 206), the display of a map on a user’s phone (paragraph 0036), a timeline shown on a user interface showing when and where a user has visited (paragraph 0045), and a request sent from a mobile device to a tracking server for information regarding a location history of a device (paragraph 0059 and figure 4). However, no art of record, discloses receiving, from the access control device, a message comprising an application ID of an application to communicate with the access control device and the information identifying the location of the access control device, wherein the application is hosted by the user device. Claim Rejections - 35 USC § 103 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 (i.e., changing from AIA to pre-AIA ) 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. 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. The factual inquiries for establishing a background for determining obviousness under 35 U.S.C. 103 are summarized as follows: 1. Determining the scope and contents of the prior art. 2. Ascertaining the differences between the prior art and the claims at issue. 3. Resolving the level of ordinary skill in the pertinent art. 4. Considering objective evidence present in the application indicating obviousness or nonobviousness. Claim(s) 1-4, 8-12, 16, and 17 is/are rejected under 35 U.S.C. 103 as being unpatentable over Vega et al. [U.S. Patent Publication 2017/0134898] in view of Sato [U.S. Patent Publication 2002/0145506], and in further view of Chao et al [U.S. Patent Publication 2014/0266585] With regard to claim 1, Vega et al. meets the limitations of: a method comprising receiving, by a processor of a user device information identifying a location [a tracking device location manager in a tracking system used for tracking the location of a device (paragraphs 0032 and 0034 as well as figure 2, item 206)] storing, on the user device, an identifier, and a timestamp referencing a current time [a timeline shown on a user interface showing when and where a user has visited (paragraph 0045)] receiving, at the user device, a request of a user of the user device for a list of locations visited within a specified time window [a request sent from a mobile device to a tracking server for information regarding a location history of a device (paragraph 0059 and figure 4) where a timeline shown on a user interface showing when and where a user has visited (paragraph 0045)] responsive to determining that the timestamp belongs to the specified time window, visually representing the identifier of the location via a graphical user interface (GUI) rendered on the user device [the display of a map on a user’s phone (paragraph 0036)] However, Vega et al. fails to disclose of an access control device.
