Office Action

§112
DETAILED ACTION Applicant’s amendment and arguments filed November 10, 2025 is acknowledged. Claims 1, 6, and 9 have been amended. Claims 4, 5, 11, and 14-20 are cancelled. Claims 22-24 has been newly added. Claims 1-3, 6-10, 12, 13, and 21-24 are currently pending. Information Disclosure Statement The information disclosure statement submitted on August 18, 2025 has been considered by the Examiner and made of record in the application. Claim Rejections - 35 USC § 112 The following is a quotation of 35 U.S.C. 112(b): (B) CONCLUSION.—The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the inventor or a joint inventor regards as the invention. The following is a quotation of 35 U.S.C. 112 (pre-AIA ), second paragraph: The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the applicant regards as his invention. Claims 1-3, 6-7, and 22-24 are rejected under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), second paragraph, as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor, or for pre-AIA the applicant regards as the invention. Claim 1 is rejected under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), second paragraph, as being incomplete for omitting essential elements, such omission amounting to a gap between the elements. See MPEP § 2172.01. The omitted elements are: the element performing the steps of “collecting…performing…predicting… searching…querying…determining…revising…and routing…”. The claim recites the steps of “collecting…performing…predicting…searching…querying…determining… revising…and routing…” without a corresponding element to perform the steps. The element, such as a service mesh and user profile submitting API calls to the service mesh, is essential for performing the identified steps. Therefore, appropriate correction is requested. Claims 2, 3, 6, 7, and 22-24 are rejected based on their dependency on claim 1. Allowable Subject Matter Claims 8-10, 12, 13, and 21 are allowed. The following is an examiner’s statement of reasons for allowance: The prior art of record taken alone and/or in combination fails to teach or fairly suggest receiving, by the service mesh, an API call requesting transmission of data to a microservice of the service mesh via a microservice chain; identifying, by the service mesh, whether the transmission of the data to the microservice via the microservice chain triggers the threshold for compressing data, wherein the threshold is a period of time that an amount of aggregated network traffic of the service mesh is predicted to exceed a threshold level based on the service mesh metrics; upon triggering the threshold for compressing data, compressing, by the service mesh, the data at a first microservice of the microservice chain; and routing, by the service mesh, data compressed by the first microservice of the microservice chain to a second microservice of the microservice chain. The prior art of record taken alone and/or in combination fails to teach or fairly suggest receiving, by the service mesh, an API call requesting transmission of data to a microservice of the service mesh via a microservice chain, wherein a data size of the data exceeds the threshold for the user profile submitting the API call; upon the data exceeding the threshold, selectively enabling, by the service mesh, compression of the data by a first microservice in the microservice chain, in response to the API call submitted by the user profile; and routing, by the service mesh, data compressed by the first microservice of the microservice chain to a second microservice of the microservice chain. Any comments considered necessary by applicant must be submitted no later than the payment of the issue fee and, to avoid processing delays, should preferably accompany the issue fee. Such submissions should be clearly labeled “Comments on Statement of Reasons for Allowance.” Response to Arguments Applicant's arguments, filed November 10, 2025, with respect to claims 1-3, 6-7, and 22-24 have been considered but are moot in view of the new ground(s) of rejection.
