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 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. The factual inquiries set forth in Graham v. John Deere Co., 383 U.S. 1, 148 USPQ 459 (1966), that are applied 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. 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. Claims 4, 14, and 18 is rejected under 35 U.S.C. 103 as being unpatentable over JIN, Rong-hua (CN 213482965 U), hereinafter “JIN”, and in view of ZHANG, Jin-guo (CN 109741494 A), hereinafter “Zhang”. Regarding claim 4, JIN does not explicitly disclose. However, Zhang discloses wherein the hardware authentication circuitry is further to: utilize symmetric key cryptography to generate the per-part unlock key at runtime to authenticate against another unlock key generated prior to runtime. [ Page,6, 4th Para. Control method of the used wireless transmission unit of the intelligent door lock system, (A1) the unlocking key data or lock key data, comprises a parity bit, encryption section and data section, the encryption section uses symmetrical key encryption, the symmetric key is also stored in the door lock control module, used for data decryption, the symmetric key is a pseudo-random number generator. [ Page 6,4th Para.(A1), the wireless key transmits unlocking key data locking key or data to the door lock control module, the door lock control module after receiving the unlocking key data or lock key data for decrypting processing, if the decryption is successful, executing (A2); if the decryption is unsuccessful, executing (A3), wherein the unlocking key data or lock key data both comprises a parity bit, an encryption section and data section, the encryption section uses symmetrical key encryption, the symmetric key is also stored in the door lock control module; for data decryption, the symmetric key is a pseudo-random number generator, a pseudo random number generator to generate a single set of pseudo-random number sequences (Rn), the pseudo-random number sequence (Rn) generation mode is (Rn) = (ARn-1 + B) mod (m)]. It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify the teaching of JIN by incorporating “symmetrical key encryption,”, as taught by Zhang. One could have been motivated to do so in order to provide symmetrical key for data decryption of the unlocking key data or lock key data which both comprises a parity bit, an encryption section and data section, [ Zhang, Page 6,4th]. Claims 14, and 18 , these claims are interpreted and rejected for the same rational set forth in claim 4. Second Set of Rejections: Claim Rejections - 35 USC § 102 The following is a quotation of the appropriate paragraphs of 35 U.S.C. 102 that form the basis for the rejections under this section made in this Office action: A person shall be entitled to a patent unless – (a)(1) the claimed invention was patented, described in a printed publication, or in public use, on sale or otherwise available to the public before the effective filing date of the claimed invention. Claims 1, 8, and 15 are rejected under 35 U.S.C. 102(a) (1) as being anticipated by Shahidzadeh ( US2016/0224810). Regarding claim 1, Shahidzadeh discloses An apparatus, comprising: first circuitry that is to be selectively locked and unlocked; second circuitry to process one or more tokens including a token for the first circuitry; and hardware authentication circuitry to authenticate the token for the first circuitry in response to a request from the second circuitry [ see FIG 1 and corresponding text for more detail, [0016] FIG. 1 illustrates a transit protection system 100 consistent with various embodiments of the present disclosure. The system 100 generally includes lock state circuitry 110, lock state read circuitry 120, lock state programmer circuitry 130( equated to authentication circuitry) and unlock service 140( equated to second circuitry). Lock state read circuitry 120 may be included in and/or coupled to device 102( equated to first circuitry). [0036] For example, lock state programmer circuitry 130 may request an unlock token from unlock service 140 for device 102. Lock state programmer circuitry 130 may read device ID 104 from lock state circuitry 110 prior to requesting the unlock token from unlock service 140. Lock state programmer circuitry 130 is configured to provide the device ID 104 to the unlock service 140. Lock state programmer circuitry 130 may provide the device ID 104 to the unlock service 140 with the request for the unlock token or in response to a request from the unlock service for the device ID 104. Unlock service 140 may request authentication from lock state programmer circuitry 130. For example, in the case of unlock token provisioning by an end user, unlock service 140 may request an identifier associated with the lock state programmer circuitry 130 and/or device 102. For example, unlock service 140 may request an order number, a customer number and/or a lock state programmer ID from the lock state programmer circuitry 130 for authentication. If authentication is successful, the unlock service 140 is configured to provide the unlock token 112 to the lock state programmer circuitry 130. The lock state programmer circuitry 130 may then provide the unlock token 112 to lock state circuitry 110. Lock state circuitry 110 may then store the unlock token 112. [0017] Lock state circuitry 110 is configured to be accessed by lock state programmer circuitry 130. For example, lock state circuitry 110 may be configured to communicate wirelessly with lock state programmer circuitry 130. For example, lock state programmer circuitry 130 may be an RFID (Radio frequency identification) programmer configured to read lock state circuitry 110 and to write data to lock state circuitry using RF. Regarding claims 8, and 15, these claims are interpreted and rejected for the same rational set forth in claim 1. Conclusion The prior art made of record and not relied upon is considered pertinent to applicant's disclosure. See submitted 892 for more relevant references. Genest; Leonard J. (US 4616491 A) (1) When adapting electronic circuits to sundry mechanisms for locking and unlocking door locks, the industry heretofore has gravitated toward use of magnetically coded cards as the vehicle for motivating the circuit to perform the locking and unlocking operations. Cards coated with a magnetic material are capable of accepting a multiple number of combinations of coded information far in excess of the number of combinations that would be possible with a conventional key. CAO, JIN(CN 109493493 B ) (2) the user can remotely control the door lock through the door opening module in the mobile phone client. the user selects the door lock to be opened by the door opening module and inputs the corresponding door opening password and selects the remote door opening option; the mobile phone client applies the session key of the authentication server to the security transmission server; the authentication server receives the application; distributing the session key to the mobile phone client and the authentication server; the mobile phone client uses the session key and uses the symmetrical encryption system to encrypt the door opening request and transmit it to the authentication server. the authentication server sends the message sent by the mobile phone client, using the session key to decrypt, and the authority associated management module for opening authentication operation to the user, if the authentication is successful, then the door lock data management module requests the related information of the door lock and calculating the door lock current door opening password, after finishing calculating; the authentication server applies the session key with the door lock to the security transmission server and uses the session key and uses the symmetric encryption system to encrypt the door opening key, and sends the encrypted message to the door lock core controller. the door lock core controller after receiving the message, using the session key to decrypt and the door key stored in the door lock information controller for calculating and verifying, if the verification is passed, controlling the lock core to drive the door Any inquiry concerning this communication or earlier communications from the examiner should be directed to SHAHRIAR ZARRINEH whose telephone number is (571)272-1207.
