DETAILED ACTION
Notice of Pre-AIA or AIA Status
The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA .
In the event the determination of the status of the application as subject to AIA 35 U.S.C. 102 and 103 (or as subject to pre-AIA 35 U.S.C. 102 and 103) is incorrect, any correction of the statutory basis (i.e., changing from AIA to pre-AIA ) for the rejection will not be considered a new ground of rejection if the prior art relied upon, and the rationale supporting the rejection, would be the same under either status.
This application currently names joint inventors. In considering patentability of the claims the examiner presumes that the subject matter of the various claims was commonly owned as of the effective filing date of the claimed invention(s) absent any evidence to the contrary. Applicant is advised of the obligation under 37 CFR 1.56 to point out the inventor and effective filing dates of each claim that was not commonly owned as of the effective filing date of the later invention in order for the examiner to consider the applicability of 35 U.S.C. 102(b)(2)(C) for any potential 35 U.S.C. 102(a)(2) prior art against the later invention.
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.
Claim(s) 4-6 and 12-16 is/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 applications subject to pre-AIA 35 U.S.C. 112, the applicant), regards as the invention.
Claim 4 recites the limitation “a connection portion of each interface circuit” in Lines 5-6. It is unclear as to whether this is intended to refer to the previously claimed “a connection portion” which is part of “each network interface circuit” of Claim 2. For the purposes of evaluating prior art with respect to patentability, the Examiner has interpreted this limitation as “the connection portion of each network interface circuit”.
Claim 12 recites the limitation “a wired telecommunication network” in the last two lines. It is unclear as to whether this is intended to refer to the previously claimed “A wired telecommunication network” of Line 1. For the purposes of evaluating prior art with respect to patentability, the Examiner has interpreted this limitation as “the wired telecommunication network”.
Claim 16 recites the limitation "the since PSE controller circuitry" in Line 2. There is insufficient antecedent basis for this limitation in the claim. It is unclear as to whether this is intended to refer to the previously claimed “single PSE controller circuitry”. For the purposes of evaluating prior art with respect to patentability, the Examiner has interpreted this limitation as “the single PSE controller circuitry”.
Dependent claims inherit the indefiniteness of their parent claims and are rejected under the same reasoning.
Claim Objections
Claim 6 is objected to because of the following informalities: the word “network” has been omitted prior to the term “interface circuit” in Line 3. Appropriate correction is required.
Claim 7 is objected to because of the following informalities: the word “network” has been omitted prior to the term “interface circuit” in Line 2. Appropriate correction is required.
Claim 8 is objected to because of the following informalities: the word “network” has been omitted prior to the term “interface circuit” in Lines 2, 4, and 7. Appropriate correction is required.

Response to Arguments
Applicant's arguments filed 12 November 2025 have been fully considered but they are not persuasive.
Applicant has argued that Brenguier does not disclose that the single PD controller circuitry and the single PSE controller circuitry are mutually configured to control electrical power flow of each of the network interface circuits (See Pages 12-13). In response, the Examiner notes that, as indicated in the interview on 23 October 2025, Elements 10 and 10’ of Figure 10 were, together, a “single PD controller circuitry” in accordance with the broadest reasonable interpretation of the term, and Elements 12 and 12’ of Figure 10 were, together, a “single PSE controller circuitry” in accordance with the broadest reasonable interpretation of the term. Notwithstanding the above, the Examiner notes that the rejection in the instant Office Action relies upon the disclosure of Figure 15, which discloses an embodiment having a single PD controller circuitry and a single PSE controller circuitry connected to multiple network interfaces. As indicated in the above rejections, the single PD controller circuitry and the single PSE controller circuitry are mutually configured to control electrical power flow of each of the network interface circuits (See Page 8 Lines 7-15, Page 8 Line 34 – Page 9 Line 3, and Page 21 Lines 26-31).
Conclusion
The art made of record and not relied upon is considered pertinent to applicant's disclosure. “Simplify PoE Implementation with Complete PD Interface and Integrated Switching Regulator” by Kirk Su discloses that a 25kΩ resistor is required in a PoE PD device between the two voltage pins of the network connection.
