With respect to claim 7, Swonger teaches wherein the second section of the panel comprises at least one signalization button (19) provided by the panel. With respect to claim 12, Swonger does not teach wherein the panel comprises a touch- sensitive display, wherein processing unit is configured to control the touch-sensitive display to provide the contrast. It would have been obvious to one having ordinary skill in the art at the time the invention was made to for elevator to have touch screen display, since it has been held to be within the general skill of a worker in the art to select a known material on the basis of its suitability for the intended use as a matter of obvious design choice. In re Leshin, 125 USPQ 416. With respect to claim 13, Swonger teaches wherein the processing unit is configured to provide the contrast by colors (column 5, lines 1-19) displayed on the touch- sensitive display. With respect to claim 20, Swonger teaches wherein the at least one memory stores the program instructions (column 3, lines 39-56; software/instructions) that, when executed on the at least one processing unit, causes the controller to receive a first trigger event from a first sensor (18). Swonger does not teach the first trigger event indicating an approaching passenger, wherein the at least one trigger signal is configured to adapt the contrast in a first section of the panel. It would have been obvious to one having ordinary skill in the art at the time the invention was made to for elevator to sense passenger approaching, since it has been held to be within the general skill of a worker in the art to select a known material on the basis of its suitability for the intended use as a matter of obvious design choice. In re Leshin, 125 USPQ 416. With respect to claim 21, Swonger teaches wherein the first section of the panel comprises at least one edge (fig. 1, 16) of the panel. With respect to claim 22, Swonger teaches wherein the at least one memory (32) stores the program instructions that, when executed on the at least one processing unit (30), causes the controller to receive the second trigger event (column 3, lines 19-57; from second input 18), from the second sensor (18), wherein the at least one trigger signal to adapt the contrast in a second section of the panel. Swonger does not teach second trigger signal indicating close proximity of the passenger to the elevator signalization device. It would have been obvious to one having ordinary skill in the art at the time the invention was made to for elevator to sense passenger approaching, since it has been held to be within the general skill of a worker in the art to select a known material on the basis of its suitability for the intended use as a matter of obvious design choice. In re Leshin, 125 USPQ 416. With respect to claim 23, Swonger teaches wherein the second section of the panel comprises at least one signalization button (19) provided by the panel. With respect to claim 28, Swonger does not teach wherein the at least one memory (32) stores the program instructions (column 3, lines 39-56; software/instructions) that, when executed on the at least one processing unit (30). Swonger does not teach the controller to control the elevator signalization device to provide the adapted contrast via a touch-sensitive display. It would have been obvious to one having ordinary skill in the art at the time the invention was made to for elevator to have touch screen display, since it has been held to be within the general skill of a worker in the art to select a known material on the basis of its suitability for the intended use as a matter of obvious design choice. In re Leshin, 125 USPQ 416. Response to Arguments Applicant's arguments filed 12/31/2025 have been fully considered but they are not persuasive. With respect to independent claims 1, 17, 29 and 20, applicant’s only argument is that applicant believes that Swonger does not teach, “a processing unit configured to: receive at least one trigger signal; and adapt contrast in at least one section of the panel based on the received at least one trigger signal.” Swonger teach the processing unit (30) and adapting contrast in one section of panel (column 3, lines 19-27). The examiner believes an illuminated LED display screen that changes, is considered to be “adapting contrast”. Conclusion THIS ACTION IS MADE FINAL.
