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 . Continued Examination Under 37 CFR 1.114 2. A request for continued examination under 37 CFR 1.114, including the fee set forth in 37 CFR 1.17(e), was filed in this application after final rejection. Since this application is eligible for continued examination under 37 CFR 1.114, and the fee set forth in 37 CFR 1.17(e) has been timely paid, the finality of the previous Office action has been withdrawn pursuant to 37 CFR 1.114. Response to Arguments 3. Applicant's arguments received 07/21/2025 have been considered but are moot in view of the new ground(s) of rejection. Detailed response is given in sections 4-7 as set forth above in this Office action. Claim Rejections - 35 USC § 103 4. 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 of this title, 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. 5. Claims 1-2, 4-6, 8-11, and 18-20 are rejected under 35 U.S.C. 103 as being unpatentable over Adifon et al. (US 20220048732 A1) in view of Huo et al. (CN 205838237 U). Regarding claims 1 and 20, Adifon discloses a hoist elevator operation system (e.g., Fig. 1.a.1) comprising: a floor call station (24) configured to be mounted to a surface (a wall near hall door 18) at a location where a user would be located to call a hoist elevator car (para. 0042), the floor call station including an up indicator button, a down indicator button, and a floor call station transmitter that transmits a floor call message when a user activates the up indicator button or the down indicator button (para. 0044, 0055), wherein the floor call message includes a called floor number and a direction of travel associated with the call (para. 0044: “The UICD 30 serves to pass appropriate signals (call, target floor, and/or other signals) to the elevator controller 20”; para. 0042: “… display on a display of ICUD 25 the direction of travel and floor location of the elevator car 12 (as well as other information) and/or emit audio signals or speech communications”, by inherency, the floor call message must include a direction of travel associated with the call); a car controller (25) comprising a wireless transceiver (para. 0052), the car controller being installed in a hoist elevator car (12), where the wireless transceiver receives the floor call message from the floor call station (para. 0042); and an operator panel installed in the hoist elevator car and operatively paired to the car controller (see discussion of ICUDs 25 in para. 0042-0045, 0048, 0059), the operator panel including a display (para. 0043: “display on a display of ICUD 25 the direction of travel and floor location of the elevator car 12 (as well as other information) and/or emit audio signals or speech communications”) and a control panel (para. 0053: “The HUFD 24 and the ICUD 25 devices may include a smart reader or other communication systems to interface with the user's mobile device 8”; para. 0059, 0070), wherein the display of the operator panel provides a visual indication of the floor call message (para. 0071, 0073, 0076), including the called floor number and called direction of travel associated with the call (para. 0042: “display on a display of ICUD 25 the direction of travel and floor location of the elevator car 12 (as well as other information) and/or emit audio signals or speech communications”; see also discussion of ICUDs 25 in para. 0043-0045, 0048, 0059). Adifon does not mention explicitly: said location is within a level of a construction site where a user would be located to call a hoist elevator car. Huo discloses a floor call station configured to be mounted to a surface at a location within a level of a construction site where a user would be located to call a hoist elevator car (see Abstract and discussion of Fig. 4). In view of Huo, it would have been obvious to one ordinary skill in the art before the effective filing date of the claimed invention to apply Adifon’s hoist elevator operation system to a construction elevator floor calling bidirectional communication system taught by Huo, as an intended use of the Adifon invention. It has been held that the mere application of a known technique to a specific instance by those skilled in the art would have been obvious. Regarding claim 2, Adifon discloses: wherein the operator panel includes a graphical user interface that provides the visual indication of the floor call message, and the graphical user interface includes an up call panel and a down call panel (para. 0071, 0073, 0076); wherein the up call panel and the down call panel each include a plurality of floor icons, and each of the plurality of floor icons includes a floor number and a travel direction arrow (para. 0037). Regarding claim 4, Adifon discloses: wherein the hoist elevator operation system comprises a plurality of floor call stations (24 in Fig. 1.a.1). Adifon is silent on: wherein the hoist elevator operation system comprises a plurality of hoist elevator cars, each hoist elevator car including a car controller and an operator panel. The feature in question is considered merely an intended use of Adifon’s hoist elevator operation system to a plurality of hoist elevator cars, each hoist elevator car including a car controller and an operator panel. It has been held that a recitation of the intended use of the claimed invention must result in a structural difference between the claimed invention and the prior art in order to patentably distinguish the claimed invention from the prior art. If the prior art structure is capable of performing the intended use, then it meets the claim. In a claim drawn to a process of making, the intended use must result in a manipulative difference as compared to the prior art. See In re Casey, 152 USPQ 235 (CCPA 1967) and In re Otto, 136 USPQ 458, 459 (CCPA 1963). Regarding claim 5, Adifon discloses: wherein each floor call station is configured to transmit the floor call message to each car controller (para. 0044). Regarding claim 6, Adifon discloses: wherein the wireless transceiver of each car controller is configured to transmit wireless signals to each other car controller (para. 0044). Regarding claims 8 and 10-12, Adifon discloses: wherein the system further comprises a remote server (e.g., user’s mobile phone 8) and a base station (20 or 30); wherein the remote server sends wireless signals to the car controller and the base station (para. 0042, 0044, 0070); wherein the wireless transceiver of the car controller sends wireless signals to the remote server (para. 0042, 0044, 0070); wherein the hoist elevator operation system comprises a plurality of floor call stations (24) and a plurality of car controllers (e.g., 23, 25, 20/30, etc. Fig. 1.a.1); wherein the operator panel includes a graphical user interface that provides the visual indication of the floor call message, and the graphical user interface includes a go to floor indicator (see discussion for claim 1 above). Regarding claim 9, Adifon is silent on: wherein the floor call message is cancelled by the car controller of the hoist elevator car that answers the floor call. Examiner takes official notice that a floor call message is cancelled by the car controller of the hoist elevator car that answers the floor call is a well-understood and/or conventional activity in a hoist elevator operation system. It has been held that the mere application of a known technique to a specific instance by those skilled in the art would have been obvious. Regarding claim 18, Adifon discloses: wherein the operator panel comprises a processor and a memory (see discussion of 25 in para. 0042). Adifon is silent on: wherein each of the plurality of floor icons further includes a call duration timer. Examiner takes official notice that each of the plurality of floor icons of the up call panel and the down call panel includes a call duration timer is a well-understood and/or conventional activity in a hoist elevator operation system. It has been held that the mere application of a known technique to a specific instance by those skilled in the art would have been obvious. Regarding claim 19, Adifon discloses: wherein the floor call station further comprises an emergency button (para. 0085). 6. Claims 3, 7 and 12-13 are rejected under 35 U.S.C. 103 as being unpatentable over Adifon et al. in view of Huo et al. further in view of LUNDMARK (EP 3663251 A1). Regarding claims 3 and 7, Adifon discloses: wherein the floor call station transmitter transmits the floor call message using wireless signals to the car controller (para. 0042); wherein the wireless transceiver of each car controller within the plurality of car controllers is configured to receive wireless signals from each floor call station and to transmit wireless signals to each other car controller of the plurality of car controllers (para. 0042, 0059). Adifon does not mention explicitly: said wireless signals are long-range (LoRa) signals or RF signals. LUNDMARK teaches transmitting long-range (LoRa) signals to each other car controller of the plurality of car controllers (para. 0131, 0133). It would have been obvious to one ordinary skill in the art, before the effective filing date of the claimed invention, to modify Adifon’s wireless signals by incorporating LUNDMARK’s LoRa signals to arrive the claimed invention. It has been held that the mere application of a known technique to a specific instance by those skilled in the art would have been obvious. Regarding claims 12-13, Adifon does not mention explicitly: wherein the go to floor indicator is modified by the operator panel based on a scheduling message received from the remote server; wherein the remote server comprises remote server logic, the remote server logic including a scheduling (or timeline) module. LUNDMARK disclose a hoist elevator operation system comprising: a floor call station (para. 0154: a floor call system) including an up indicator button, a down indicator button, and a floor call station transmitter that transmits a floor call message when a user activates the up indicator button or the down indicator button (para. 0154); a car controller comprising a wireless transceiver (106 Fig. 1), where the wireless transceiver receives the floor call message from the floor call station (para. 0128-0129); and an operator panel operatively paired to the car controller including a display and a control panel (para. 0136), wherein the display of the operator panel provides a visual indication associated with the floor call message (para. 0026, 0136, 0167); wherein the operator panel includes a graphical user interface that provides the visual indication associated with the floor call message, and the graphical user interface includes a go to floor indicator (para. 0026, 0136, 0167); wherein the go to floor indicator is modified by the operator panel based on a scheduling message received from a remote server (para. 0059, 0065, 0077-0078, 0080); wherein the remote server comprises remote server logic, the remote server logic including a scheduling (or timeline) module (para. 0024, 0079-0080). It would have been obvious to one ordinary skill in the art, before the effective filing date of the claimed invention, to modify Adifon’s operator panel and the remote server as taught by LUNDMARK to arrive the claimed invention. One of ordinary skill in the art would have recognized that the results of such a combination were predictable for percussion electronic device since the use of that known technique provides the rationale to arrive at a conclusion of obviousness. See KSR International Co. v. Teleflex Inc., 82 USPQ2d 1385 (U.S. 2007). 7. Claims 14-17 are rejected under 35 U.S.C. 103 as being unpatentable over Adifon et al. in view of Huo et al. further in view of Takeuchi. Regarding claims 14-17, Adifon discloses: wherein the operator panel includes a graphical user interface that provides the visual indication associated with the floor call message (para. 0071, 0073, 0076). Adifon is silent on: the graphical user interface includes a plurality of floor icons, each floor icon having at least two operating states; wherein a first operating state of each floor icon is a selected state, and a second operating state of each floor icon is an unselected state; wherein each floor icon further has a third operating state, and the third operating state is a current floor state; wherein the control panel is built into the display in the form of a touchscreen. Takeuchi teaches: an operator panel includes a graphical user interface (a touch panel operated by a user) that provides the visual indication associated with the floor call message, the graphical user interface includes a plurality of floor icons, each floor icon having at least two operating states, wherein a first operating state of each floor icon is a selected state, and a second operating state of each floor icon is an unselected state, wherein each floor icon further has a third operating state, and the third operating state is a current floor state (col. 3, lines 44-62); wherein a control panel is built into the display in the form of a touchscreen (col. 3, lines 44-62). It would have been obvious to one ordinary skill in the art, before the effective filing date of the claimed invention, to incorporate Takeuchi’s teaching of the graphical user interface into Adifon to arrive the claimed invention thus improving the feasibility and applicability of the Adifon invention.
