Office Action

§103
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 This office action is in response to communication filed 5/28/26. Response to Arguments Applicants’ arguments filed on 5/28/26 have been fully considered but they are not persuasive. Applicant argues that the prior art of Luongo alone or in communication with the secondary references does not teach of suggests the applicant’s invention. It is the examiner’s position that the reference of Luongo teaches controlling access to a restricted access zone which includes an access control device and a barrier free lock (paragraph 07-08,019). Luongo teaches a display for displaying an event log and to provide a visual or audio alarm (paragraph 014,024,072). Luongo also teaches the display includes a real time display of the captured image (fig. 4C,4D, paragraph 074-76). Luongo teaches providing an indication that the access is unauthorized (135, fig.4C). The reference of Trini is also relied upon for teaching Trani in an analogous art teaches activating the display device to display access is approve and activating the display to display an alarm message when a valid credential is not identified (col. 11 lines 31-52). In response to applicant’s argument that the displaying of the information as disclosed by the reference of Luongo is different from the claimed limitation, it is the examiner’s position that the reference of Luong teaches capturing and displaying the image of the person as claimed (fig. 4C,4D, paragraph 074-76). The claimed limitations are broader than argued and the displaying of image of the approaching person reads on the claimed limitation. 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). Luongo is not explicit in teaching activating the display device to display access is approve and activating the display to display an alarm message when a valid credential is not identified. Trani in an analogous art teaches activating the display device to display access is approve and activating the display to display an alarm message when a valid credential is not identified (col. 11 lines 31-52). It would have been obvious to one of ordinary skill in the art to modify the system of Luongo at the time of the invention as disclosed by Trani because such modification represents an improvement over the system of Luongo by providing an easily perceivable indication for indicating the authentication status of a person entering the secured area and enabling immediate action to be taken when necessary. Regarding claim 18, Luongo teaches detecting a face of the person in the image data generated for the person and generating the real-time image that comprises the face of the person (paragraph 065). Regarding claim 19, Luongo teaches detecting a face of the person in the image data generated for the person and generating the real-time image that comprises the face of the person (paragraph 065). Regarding claim 23, Luongo teaches storing the real-time image in a storage device with the access control device when the alarm message is provided (paragraph 070-071). Regarding claim 25, Luongo is silent on teaching activating a camera system with the access control device when the alarm message is issued in order to track the person in the restricted-access zone (paragraph 051). Regarding claim 27, Luongo teaches system for controlling access to a restricted-access zone in a building or on a site, the system comprising: an access control device (300, paragraph 050); and a barrier-free lock at an entrance to the restricted-access zone (810, paragraph 080), 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), wherein the display device is configured 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 recording device is configured to record a credential of the person (camera, paragraph 08,019), wherein the image recording device is configured to generate the image data when the person is present at the barrier-free lock in order to enter the restricted-access zone (paragraph 051), and wherein the access control device is configured to: check whether the recording device records a credential 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). Luongo is not explicit in teaching activating the display device to display access is approve and activating the display to display an alarm message when a valid credential is not identified. Trani in an analogous art teaches activating the display device to display access is approve and activating the display to display an alarm message when a valid credential is not identified (col. 11 lines 31-52). It would have been obvious to one of ordinary skill in the art to modify the system of Luongo et at the time of the invention as disclosed by Trani because such modification represents an improvement over the system of Luongo by providing an easily perceivable indication for indicating the authentication status of a person entering the secured area and enabling immediate action to be taken when necessary. Regarding claim 28, Luongo et at teaches the recording device is configured to record at least a biometric feature (paragraph 065). Regarding claim 31, Luongo teaches detecting a face of the person in the image data generated for the person, and wherein the display device is configured to display the image data as a real-time image which comprises the face of the person (paragraph 065). Regarding claim 32, Luongo teaches detecting a face of the person in the image data generated for the person, and wherein the display device is configured to display the image data as a real-time image which comprises the face of the person (paragraph 065). Regarding claim 35, Luongo is silent on teaching activating a camera system with the access control device when the alarm message is issued in order to track the person in the restricted-access zone (paragraph 051).

US Patent Application Publication 20220215729 in view of Trani US Patent 9,947155 and further in view of Polcha et al. US Patent Application Publication 20060136743. Regarding claim 17, Luongo teaches detecting a presence of the person at the barrier-free lock (paragraph 051) and providing an image along with an alert (fig.4D) but is silent on teaching actuating the display device to generate at least one of an audible cue or visible cue for the person to identify themselves, wherein the audible cue comprises a voice message and wherein the visible cue comprises at least one of displaying the voice message as text or displaying an optical effect in conjunction with the real-time image. Polcha et al in an analogous art teaches actuating the display device to generate a visible cue for the person to identify themselves, and wherein the visible cue comprises at least one of displaying the voice message as text or displaying an optical effect in conjunction with the real-time image (fig.2(a), paragraph 040). It would have been obvious to one of ordinary skill in the art at the time of the invention to modify the system of Luongo in view of Trani as disclosed by Polcha because such modification represents an improvement over the system Luongo in view of Trani by providing instruction to the user in order to verify the user’s identity. Regarding claim 24, Luongo teaches storing the real-time image in a storage device with the access control device when the alarm message is provided (paragraph 070-071). Regarding claim 29-30, Luongo teaches detecting a presence of the person at the barrier-free lock (paragraph 051) and providing an image along with an alert (fig.4D) but is silent on teaching actuating the display device to generate at least one of an audible cue or visible cue for the person to identify themselves, wherein the audible cue comprises a voice message and wherein the visible cue comprises at least one of displaying the voice message as text or displaying an optical effect in conjunction with the real-time image. Polcha et al in an analogous art teaches actuating the display device to generate a visible cue for the person to identify themselves, and wherein the visible cue comprises at least one of displaying the voice message as text or displaying an optical effect in conjunction with the real-time image (fig.2(a), paragraph 040). It would have been obvious to one of ordinary skill in the art at the time of the invention to modify the system of Luongo in view of Trani as disclosed by Polcha because such modification represents an improvement over the system Luongo in view of Trani by providing instruction to the user in order to verify the user’s identity.
