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.
This application currently names joint inventors. In considering patentability of the claims the examiner presumes that the subject matter of the various claims was commonly owned as of the effective filing date of the claimed invention(s) absent any evidence to the contrary. Applicant is advised of the obligation under 37 CFR 1.56 to point out the inventor and effective filing dates of each claim that was not commonly owned as of the effective filing date of the later invention in order for the examiner to consider the applicability of 35 U.S.C. 102(b)(2)(C) for any potential 35 U.S.C. 102(a)(2) prior art against the later invention.
Claim(s) 2 is/are rejected under 35 U.S.C. 103 as being unpatentable over US_20240114406_A1_Zhou (Hereinafter, “Zhou-06”) in view of US_20250301433_A1_Zhang and US_20230362853_A1_Kung.

Thus it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to implement the teachings of Zhou-54’s the UE receiving PDCCH order (e.g., a DCI format 1_0 with C-RNTI and FDRA field being set to all ones) triggering a RA procedure in Zhou-06’s system to instruct the UE to start a Contention-Free Random Access (CFRA) procedure (Zhou-54 paragraph 417). This method for improving the system of Zhou-06 was within the ordinary ability of one of ordinary skill in the art based on the teachings of Zhou-54. Therefore, it would have been obvious to one of ordinary skill in the art to combine the teachings of Zhou-06 and Zhou-54 to obtain the invention as specified in claim 13.
Claim(s) 14 is/are rejected under 35 U.S.C. 103 as being unpatentable over US_20240114406_A1_Zhou (Hereinafter, “Zhou-06”) in view of US_20240187954_A1_Zhou (hereinafter, “Zhou-54”) and US_20230388871_A1_Guo.

Guo discloses the first DCI comprises at least one field of Identifier for DCI formats, and the field of Identifier for DCI formats is set to 1 (Guo page 37, Table 6.2-1, “Identifier for DCI formats…The value of this bit field is always set to 1, indicating a DL DCI format… If the CRC of the DCI format l_0 is scrambled by C-RNTI and the "Frequency resource assignment domain resource assignment" field are of all ones, the DCI format 1_0 is for random access procedure initiated by a PDCCH order…”).
Thus it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to implement the teachings of Guo’s Identifier for DCI formats in Zhou-06 and Zhou-54’s system to notify the UE the DCI format. This method for improving the system of Zhou-06 and Zhou-54 was within the ordinary ability of one of ordinary skill in the art based on the teachings of Guo. Therefore, it would have been obvious to one of ordinary skill in the art to combine the teachings of Zhou-06, Zhou-54, and Guo to obtain the invention as specified in claim 14.
