CTFR 18/206,462 CTFR 83633 DETAILED ACTION 1. It is hereby acknowledged that 18/206462 the following papers have been received and placed of record in the file: Amended date 09/12/25 07-03-fti AIA 2. The present application is being examined under the pre-AIA first to invent provisions. Amendment date 09/12/25. Claims 1-10 and 23-29 are presented for examination. Claims 1, 23, and 25 are being amended. Claim Objection 07-29-01 AIA 3. Claim s 1-10, 23-29 are objected to because of the following informalities: Claim 1 and 23 recites “….header indicating address information of the second STA”. It is unclear and vague what is considered of the second STA. Address information is considered vague as well. The specification does not seem to provide further clarification. These claims also explain a first MLD and a second MLD, meanwhile the specification seems to explain an AP MLD and NON-AP MLD( see paragraphs [0065]-[0070], [0075]-[0085],[0097]-[0105]. This leaves one questioning what the true meaning of these limitations. It is also hard to see where the third STA and fourth STA is explained, which can also be considered lacking support . Appropriate correction is required. Response to Arguments 4 Applicant’s arguments with respect to claim(s) 1-10, 23-29 have been considered but are moot because the new ground of rejection does not rely on any reference applied in the prior rejection of record for any teaching or matter specifically challenged in the argument.

Patentability shall not be negatived by the manner in which the invention was made. 07-23-aia AIA 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. 07-21-aia AIA 6.

(canceled) Regarding claim 23 , IEEE teaches a system of communication between a first multi-link device (MLD) and a second MLD, the first MLD being affiliated with a first station (STA) and a third STA, the second MLD being affiliated with a second STA and a fourth STA, wherein: the first STA is configured for: generating a management frame comprising a header indicating a second MLD; (see IEEE slide 3, 10, 14,15 MLD MAC addr….STA1 to non-AP) and sending the generated management frame to the first MLD; the first MLD is configured for: receiving, from the first STA, the management frame; encrypting the management frame based on a security association established between the first MLD and the second STA; (see IEEE slide 3,5, 10, 15 AP MLD/Authenticator to non-AP MLD, security association PMKSA, PTSA, SN assignment for frames to be encrypted by PTK and EAPol-Key, MAC header of OTA….MAC addresses of transmitter and receiver) and sending the encrypted management frame toward the second MLD via one of the first STA and the third STA. (see IEEE slides 3, 10, 14, 15 AP MLD/Authenticator to non-AP MLD and EAPol-Key and reverse) While the IEEE frame can be understood to be a management frame since it is being used as part of assigning, assigning and security as explained above However analogous art Yang page 16 line 1-line 12 explains at least in an embodiment, frames associated with the ML traffic stream, such as the data frames encapsulating data of the ML traffic stream, the management frames and control frames related to the data operations of the ML traffic stream, etc., are generated (during the transmitting) and processed (during the receiving) by the MAC entity of the transmitting and receiving RCMs operating on the master channels (i.e., the master RCMs), respectively, no matter the frames are transmitted or received over shared channel 1310 or shared channel 2 312. It would have been obvious to one of ordinary skill in the art before the effective filling data of the claimed invention to combine IEEE with Yang. One of ordinary skill in the art would have been motivated to make this modification before the effective filling data of the claimed invention to improve aggregation of communication channels (see background) Regarding claim 24 , the modified IEE taught the system of claim 23, as described above.
