Office Action

§102
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 . DETAILED ACTION General Remarks 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 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. When responding to this office action, applicants are advised to provide the examiner with line numbers and page numbers in the application and/or references cited to assist the examiner in locating appropriate paragraphs. Per MPEP 2111 and 2111.01, the claims are given their broadest reasonable interpretation and the words of the claims are given their plain meaning consistent with the specification without importing claim limitations from the specification. Applicants seeking an interview with the examiner, including WebEx Video Conferencing, are encouraged to fill out the online Automated Interview Request (AIR) form (http://www.uspto.gov/patent/uspto-automated-interview-request-air-form.html). See MPEP §502.03, §713.01(II) and Interview Practice for additional details. Applicant's cooperation is requested in correcting any errors of which applicant may become aware in the specification. Status of claim to be treated in this office action: Independent: 1 and 15. b. Claims 1-15 are pending on the application. Drawings 2. The drawings were received on 02/03/2025. These drawings are review and accepted by examiner. Priority 3. Receipt is acknowledged of papers submitted under 35 U.S.C. 119(a)-(d), which papers have been placed of record in the file. Information Disclosure Statement 4. Acknowledgment is made of applicant’s Information Disclosure Statement (IDS) Form PTO-1449; filed 02/03/2025. The information disclosed therein was considered. Specification 5. Applicant is reminded of the proper language and format for an abstract of the disclosure. The abstract should be in narrative form and generally limited to a single paragraph on a separate sheet within the range of 50 to 150 words. It is important that the abstract not exceed 150 words in length since the space provided for the abstract on the computer tape used by the printer is limited. The form and legal phraseology often used in patent claims, such as "means" and "said," should be avoided. The abstract should describe the disclosure sufficiently to assist readers in deciding whether there is a need for consulting the full patent text for details. The language should be clear and concise and should not repeat information given in the title. It should avoid using phrases which can be implied, such as, "The disclosure concerns," "The disclosure defined by this invention," "The disclosure describes," etc. The abstract of the disclosure is objected to because it uses the phrase “OF THE DICLOSURE” in page 1, line 1, which is implied. Correction is required. See MPEP § 608.01(b). Claim Rejections - 35 USC § 102 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. 6.

With respected to dependent claim 5, the prior art fails to tech or suggest the claimed limitations, namely, the long-pulse detection circuit includes a resistance element, a capacitance, a second transistor, and an inverter,a gate of the second transistor is connected to the third terminal,a source of the second transistor is connected to the resistance element, the capacitance, and the inverter,a drain of the second transistor is connected to a logic power supply,in the resistance element, a terminal on an opposite side to a terminal connected to the source of the second transistor is connected to a logic ground,in the capacitance, a terminal on an opposite side to a terminal connected to the source of the second transistor is connected to the logic power supply, andthe inverter is connected to the logic circuit. With respected to dependent claims 11-13, the prior art fails to tech or suggest the claimed limitations, namely, a second resistance element arranged on the semiconductor substrate and connected between the first terminal and the first transistor in parallel to the anti-fuse element, wherein the resistance element included in the long-pulse detection circuit and the second resistance element are made of a common material, wherein the common material is a diffusion resistance. Conclusion Examiner's note: Examiner has cited particular columns and line numbers in the references as applied to the claims above for the convenience of the applicant. Although the specified citations are representative of the teachings of the art and are applied to the specific limitations within the individual claim, other passages and figures may apply as well. It is respectfully requested from the applicant in preparing responses, to fully consider the references in entirety as potentially teaching all or part of the claimed invention, as well as the context of the passage as taught by the prior art or disclosed by the Examiner. The prior art made of record and not relied upon is considered pertinent to applicant's disclosure. Dono (US. 2010/0124139 A1) discloses semiconductor device including an anti-fuse element. Candelier et al (US. 2013/0294142 A1) discloses method for controlling the breakdown of an antifuse memory cell.
