DETAILED ACTION
This office action is in response to the reply filed on 02/23/2026.
Claims 1, 3-11, 14-18, and 21-25 are pending in the application and have been examined.
Claim Rejections - 35 USC § 112
The following is a quotation of the first paragraph of 35 U.S.C. 112(a):
(a) IN GENERAL.—The specification shall contain a written description of the invention, and of the manner and process of making and using it, in such full, clear, concise, and exact terms as to enable any person skilled in the art to which it pertains, or with which it is most nearly connected, to make and use the same, and shall set forth the best mode contemplated by the inventor or joint inventor of carrying out the invention.
Claims 1, 3-11, 14-18, and 21-25 are rejected under 35 U.S.C. 112(a) or 35 U.S.C. 112 (pre-AIA ), first paragraph, as failing to comply with the written description requirement. The claim(s) contains subject matter which was not described in the specification in such a way as to reasonably convey to one skilled in the relevant art that the inventor or a joint inventor, or for applications subject to pre-AIA 35 U.S.C. 112, the inventor(s), at the time the application was filed, had possession of the claimed invention.
Claim 1 recites the limitation “circuitry to execute one or more instructions on a plurality of compute units to, in response to an indication that threads in a first compute unit of the plurality of compute units are grouped into one or more warp groups: cause matrix multiply accumulate (MMA) operations to be performed by the first compute unit to cause two or more second instructions to be performed”. This limitation requires executing one or more instructions to cause matrix multiply accumulate operations to be performed, wherein the matrix multiply accumulate operations themselves cause two or more different instructions to be performed. No support for this subject matter can be found in the original teachings of the application. In contrast, the specification (and the original claims) teaches the concept of executing an instruction that causes other instructions to execute, where the other instructions then cause the matrix multiple accumulate operations to occur. The claim therefore fails to meet the requirements of 35 U.S.C. 112(a). Claims 9 and 15 suffer from the same deficiency.
