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 .
Claim Objections
Claims 1-7 are objected to because of the following informalities: Claim 1, line 7 recites, “current valve”, which should be corrected to “current value”.. Appropriate correction is required.
Claim Rejections - 35 USC § 102
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.
The following is a quotation of the appropriate paragraphs of 35 U.S.C. 102 that form the basis for the rejections under this section made in this Office action:
A person shall be entitled to a patent unless –
(a)(1) the claimed invention was patented, described in a printed publication, or in public use, on sale, or otherwise available to the public before the effective filing date of the claimed invention.
Claims 1, 3-4, 6-9,11,13-16, 19-20 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Sexton et al. (US 2011/0063768).

Claim Rejections - 35 USC § 103
The following is a quotation of 35 U.S.C. 103 which forms the basis for all obviousness rejections set forth in this Office action:
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.
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.
Claims 2, 5,10, 12, 17-18 are rejected under 35 U.S.C. 103 as being unpatentable over Sexton et al. (US 2011/0063768) in view of Jimenez et al. (US 2019/0036324).
Regarding Claim 2, Sexton does not specifically disclose the system as defined in Claim 1, wherein said processor is further configured to adjust said pre-established threshold value based on one or more environmental factors; said environmental factors include one or more factors selected from the group consisting of ambient temperature, ambient pressure, and ambient humidity.
Jimenez discloses an intelligent circuit breaker system (Figures 1-6) comprising:
a current sensor that is configured to measure electrical current applied to a power line load (comprising current sensor 20, Figures 1-2);
a memory storing trip curve data corresponding to a trip curve of an associated circuit breaker (memory 30 in processor 28, Figures 1-2, trip curves, Figures 3-4);
a processor that is configured to receive a measured current value from said current sensor (processor 28, Figures 1-2);
wherein said processor is further configured to adjust said pre-established threshold value based on one or more environmental factors (110, 214, Figures 3-4 respectively); said environmental factors include one or more factors selected from the group consisting of ambient temperature, ambient pressure, and ambient humidity (adjusting trip time based on ambient temperature, 104, 204, Figures 3-4 respectively). It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to provide in the system of Sexton, adjusting the pre-established threshold value as taught by Jemenez, to more accurately determine the overcurrent event accounting for the changes due to environmental factors and thus to increase safety of operation.
Regarding Claim 5, Sexton does not specifically disclose the system as defined in Claim 1, wherein said processor is further configured to adjust said pre-established threshold value based on one or more environmental factors;
said environmental factors include one or more factors selected from the group consisting of ambient temperature, ambient pressure, and ambient humidity.
Jimenez discloses an intelligent circuit breaker system (Figures 1-6) comprising:
a current sensor that is configured to measure electrical current applied to a power line load (comprising current sensor 20, Figures 1-2);
a memory storing trip curve data corresponding to a trip curve of an associated circuit breaker (memory 30 in processor 28, Figures 1-2, trip curves, Figures 3-4);
a processor that is configured to receive a measured current value from said current sensor (processor 28, Figures 1-2);
wherein said trip curve data stored in said memory includes multiple predefined trip curves (trip curves 50-58, Figures 3-4);
said processor is configured to select an appropriate trip curve based on said type of load connected to said power line (108, 210, Figures 3-4 respectively).
It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to provide in the system of Sexton, multiple trip curve data as taught by Jemenez, to safely operate the system based on the type of load and its characteristics.
Claims 10, 12 recite the method of Claim 8 with corresponding limitations as Claims 5, 2 respectively. Therefore, Claims 10, 12 are rejected for the same reasons as for Claims 5, 2 respectively.
Claims 17-18 recite the method of Claim 15 with corresponding limitations as Claims 5, 2 respectively. Therefore, Claims 17-18 are rejected for the same reasons as for Claims 5, 2 respectively.
Conclusion
The prior art made of record and not relied upon is considered pertinent to applicant's disclosure. Hosko et al. (US 2023/0133287) discloses an intelligent circuit breaker system (Figures 1-5) comprising: a current sensor that is configured to measure electrical current applied to a power line load (comprising current sensor 20, Figure 1), and a memory storing trip curve data corresponding to a trip curve of an associated circuit breaker (trip curve data 40 associated with circuit breaker 16, Figures 1-2, Paragraph 26).
