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 Election/Restrictions Applicant’s election without traverse of Invention I in the reply filed February 22, 2026 and Species B in the replay filed December 11, 2025 is acknowledged. Claims 17-20 drawn to the non-elected invention(s)/species have been canceled by Applicant. 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. (a)(2) the claimed invention was described in a patent issued under section 151, or in an application for patent published or deemed published under section 122(b), in which the patent or application, as the case may be, names another inventor and was effectively filed before the effective filing date of the claimed invention. Claims 1-2, 11-12, and 28-29 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by US 2007/0188194 to Yang et al. (“Yang”). With respect to claim 1, Yang discloses in Fig. 6 an integrated circuit, comprising: a level-shifting subcircuit (e.g., 320), configured to generate a first control signal (e.g., N13) within a first power domain (e.g., VPP) and a second control signal (e.g., output of 336) within a second power domain (e.g., VDD) in response to an input voltage signal (e.g., INS1); and a driving circuit (e.g., 350), configured to generate an output voltage signal (e.g., OUT) within the first power domain (e.g., VPP) in response to the first control signal (e.g., N13) and the second control signal (e.g., output of 336), wherein a voltage range of the first power domain (e.g., VPP) differs from that of the second power domain (e.g., VPP is higher than VDD per Paras. 7-8). With respect to claim 2, the level-shifting subcircuit (e.g., 320) comprises a cross-coupled latch circuit (e.g., 328 and 330) and a first inverter (e.g., 336), and the driving circuit (e.g., 350) comprises a voltage pull-up device (e.g., 352) and a voltage pull-down device (e.g., 354). With respect to claim 11, the above discussion for claim 1 similarly applies. Further, the output signal (e.g., OUT) has a voltage range wider than that of the input range (e.g., (e.g., VPP level of OUT is higher than VDD level of INS1 per Paras. 7-8). With respect to claim 12, the above discussion for claim 2 similarly applies. With respect to claim 28, the above discussion for claim 2 similarly applies. With respect to claim 29, the first inverter (e.g., 336) is coupled between a first power supply voltage (e.g., VDD) and a reference voltage (e.g., VSS) which constitute a first power domain (e.g., VDD); the cross-coupled latch circuit (e.g., 328 and 330) is coupled between a second power supply voltage (e.g., VPP) and the reference voltage (e.g., VSS) which constitute a second power domain (e.g., VPP); and the second power supply voltage (e.g., VPP) is higher than the first power supply voltage (e.g., VDD). Allowable Subject Matter Claims 3-4, 6, 13-14, 21-27, and 30-31 are objected to as being dependent upon a rejected base claim, but would be allowable if rewritten in independent form including all of the limitations of the base claim and any intervening claims. Conclusion Any inquiry concerning this communication or earlier communications from the examiner should be directed to Jung KIM whose telephone number is (571)270-7964. The examiner can normally be reached on M-F from 9AM to 5:30PM.
