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.
The factual inquiries 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.
Claims 1, 3-5, 7, 9, 10, 13-15, 17, 18 are rejected under 35 U.S.C. 103 as being unpatentable over Hu (US 20230007661 A1) in view of Tian et al. (US 20200187244 A1).
Regarding claim 1, Hu teaches,
A method performed by a wireless device functioning as an access point (AP) in a wireless network, the method comprising:
generating a beacon frame that includes information for allocating a [restricted access window (RAW) that includes one or more RAW] slots (paragraphs 0042 – The wireless node generates a beacon signal advertising multiple time slots) that each includes a low latency transmission (LLT) contention period and a non-LLT contention period; and (paragraph 0039 – A subset of the slots include latency sensitive links for prioritized access. Paragraph 0070 – A portion of the slot includes prioritized access for latency sensitive traffic. In the same slot if the latency sensitive traffic finishes early, the slot can be used for non-latency sensitive traffic. Paragraph 0071 – In another example a first portion of every slot can be used for prioritized latency sensitive traffic and the rest of the slot can be used for regular traffic).
wirelessly transmitting the beacon frame to allocate the [RAW]. (Paragraph 0011 – The advertisement of a set of links that satisfy a low latency parameter. Paragraph 0013 – “The advertisement message can include at least one of: a beacon signal, a probe response or an action frame.” Figure 1, labels 140, 160, Paragraph 0056 – The advertisement and subsequent request for the links by a wireless node from a wireless device is done through a network.)
