The distinction that mattered
The examiner’s reasons for allowance identify a specific limitation: routing, streaming and reply capture take place under a single session authority boundary, and retrieval or streaming of the prerecorded media file does not create a new session authority. The examiner found that the cited St. Onge and Moore combination did not teach that limitation.
In plain language, the prosecution focused on what governs the changing interaction, beyond merely keeping a transport connection available. The issued claims set out the complete combination of required elements.
How the record developed
September 4, 2025: U.S. application filed
Application 19/318,971 sought protection for the communication method and related system and medium.
November 19, 2025: PCT search report transmitted
The international search record belongs to PCT/US2025/044821. It is a separate examination record from the U.S. prosecution summarized below.
November 28, 2025: non-final Office Action
The U.S. examiner rejected claims over combinations of prior art, including St. Onge and Moore, with additional references applied to certain dependent claims.
February 24, 2026: examiner interview
The interview summary records a proposed amendment requiring a single session authority boundary and no new session authority during retrieval or streaming. It records the examiner’s agreement that the proposed amendment would overcome the pending rejection.
March 2, 2026: amendment and response
The applicant submitted amended claims and argued that transport and signaling continuity did not supply the claimed authority continuity. That argument is the applicant’s position; the examiner’s subsequent reasons identify the basis for allowance.
April 7, 2026: Notice of Allowance
Claims 1–20 were allowed. The reasons state that the applicant’s arguments were persuasive and identify the single-authority limitation absent from the cited combination.
June 16, 2026: patent issued
U.S. Patent No. 12,659,408 B2 issued with 20 claims. The issued claim text is the reference version presented here.
