Claim Rejections - 35 USC § 103
22 In the event the determination of the status of the application as subject to AIA 35 U.S.C. 102 and 103 (or as subject to pre-AIA 35 U.S.C. 102 and 103) is incorrect, any correction of the statutory basis (i.e., changing from AIA to pre-AIA ) for the rejection will not be considered a new ground of rejection if the prior art relied upon, and the rationale supporting the rejection, would be the same under either status.
23 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.
24 Claim(s) 18 is/are rejected under 35 U.S.C. 103 as being unpatentable over Choi et al. (US 20220345773 A1) in view of Hazama et al. (US 20040039927 A1) and McGraw et al. (US 6300980 B1).
25 Regarding claim 18, Choi teaches the electronic system of claim 17 (see claims 15 and 17 rejections above), and although could teach wherein: the first slave address is A0h and A1h, and the second slave address is A4h and A5h ([0177] reciting “The display device 100 may write the EDID modified as described above, in a memory to be accessed and read by the source device 500. The display device 100 may modify and use EDID whenever an event for EDID modification occurs, or may store original EDID and modified EDID together and select and use the stored modified EDID when the modified EDID is required.”), prior art from Hazama can teach this limitation further.
26 Hazama teaches wherein: the first slave address is A0h and A1h ([0050] reciting “In the communication according to the I.sup.2C bus method, slave addresses are allotted to the respective slave devices. For example, typically, address "A0h" is allotted for reading and address "A1h" is allotted for writing in transmitting and receiving of EDID. Further, address "76h" is allotted for reading and address "77h" is allotted for writing at the receiver according to the HDCP method. The interface circuit 36 of this embodiment is designed so as to respond when slave address "A0h" and "A1h" allotted for EDID responses are specified as well as slave addresses "7Ah" and "7Bh" allotted for the receiver according to the HDCP method.”)…
27 It would have been obvious to one with ordinary skill before the effective filing date of the claimed invention, to have modified the method (taught by Choi) to incorporate the teachings of Hazama to provide a clearer method that provides A0h and A1h for the slave address methods and the EDID methods as taught by the teachings of Choi. Doing so would have the slave address to be allotted to the respective slave devices as stated by Hazama ([0050] recited).
28 Choi in view of Hazama could teach wherein: …, and the second slave address is A4h and A5h (see above), prior art from McGraw can teach this limitation further.
29 McGraw teaches wherein: …, and the second slave address is A4h and A5h ([Page 4-5]: see figures below; [Page 6; Column 5, Lines 59-67] reciting “The first EDID extension block will be at I.sup.2 C address A0h, offset 80h. The next EDID extension block will be at I.sup.2 C address A2h, offset 00h. The next EDID extension will be at I.sup.2 C address A2h, offset 80h, and so on. If there is more than one EDID extension, each EDID extension block should be checked for the above signature. The address and offset at which the signature are found establish slave read address (SRA), slave write address (SWA), and start-of-block (SOB) for the control panel interface.”).
