DETAILED ACTION The application of Tobias Friedli for Access Control System With Barrier-Free Access filed 11/26/24 has been examined. Claims 16-35 are pending. Claim Rejections - 35 USC § 103 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. Claim(s) 16,18-19,23,25,27-28,31-32, and 35 is/are rejected under 35 U.S.C. 103 as being unpatentable over Luongo et al. US Patent Application Publication 20220215729 in view of Trini US Patent 9,947155. Regarding claim 16, Luongo teaches a method for operating a system for controlling access to a restricted access zone in a building or on a site, wherein the system comprises an access control device and a barrier-free lock at an entrance to the restricted-access zone (paragraph 050), wherein the barrier-free lock is communicatively connected to the access control device and comprises a display device (paragraph 013-014), a recording device and an image recording device (camera, paragraph 08,019), the method comprising: activating the display device to display image data of a person generated by the image recording device as a real-time image visible to the person (paragraph 013,072), wherein the image recording device generates the image data when the person is present at the barrier-free lock in order to enter the restricted-access zone (paragraph 072); checking, with the access control device, whether a credential is recorded by the recording device and whether the credential recorded by the recording device is valid (paragraph 051). Luongo teaches if a valid credential is identified for the person, generating an approval signal with the access control device and if a valid credential is not identified for the person, generating an alarm message with the access control device (paragraph 078).
