Office Action

§102 §103
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 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. DETAILED ACTION This Office action is in response to the application filed on June 2, 2023. Foreign Priority Receipt is acknowledged of certified copies of papers submitted under 35 U.S.C. 119 (a)-(d), which papers have been placed of record in the file. Specification The specification has not been checked to the extent necessary to determine the presence of all possible minor errors. The applicant's cooperation is requested in correcting any errors of which the applicant may become aware in the specification. The abstract of the disclosure is objected to because it exceeds the word limit. Correction is required. See MPEP § 608.01(b). 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 in length. 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. In addition, the form and legal phraseology often used in patent claims, such as “means” and “said,” should be avoided. Claim Objections Claims 1-9 are objected to because of the following informalities: Claim 1 Lines 17 & 21, “pressedepressed” should be --pressed-- Claims 1-9 Line 1, “postbucklingaccording” should be --postbuckling according-- Claims 1 & 5 Lines 17 & 21, and line 3, “depressed” should be --pressed-- Appropriate correction is required. Claim Rejections - 35 USC § 102 The following is a quotation of the appropriate paragraphs of AIA 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.

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 of this title, 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. Claim 4 is rejected under 35 U.S.C. 103 as being unpatentable over Clingman in view of Rastegar et al. (U.S. Publication No. 20130049538; hereinafter “Rastegar”). Regarding claim 4, Clingman discloses the self-powered pressure sensor (Fig. 1, 10; [Abstract]) based on postbuckling (Fig. 1; [Abstract]) according to claim 2, wherein the first elastic element (Fig. 1, 26; [0030]) and the second elastic element (Fig. 1, 30; [0030]), the first elastic element (Fig. 1, 26; [0030]) is connected between (Fig. 1) the slider (Fig. 2, 38) and the chutes (Fig. 2, 42), and the second elastic element (Fig. 1, 30; [0030]) is connected between (Fig. 1) the middle part (Fig. 1, middle part of 28; [0035]) of the flexible piezoelectric sheet (Fig. 1, 28; [0035]) and the cover plate (Fig. 1, 16; [0028]). Clingman does not teach two elastic elements made of springs. Rastegar, however, does teach two elastic elements made of springs (Fig. 4, 304/402; [0033]). It would have been obvious to one with ordinary skill in the art before the effective filing date of the claimed invention to have modified the device of Clingman to include the springs of Rastegar because it would limit the magnitude of the force acting on the piezoelectric thereby protecting the piezoelectric from damage and improving durability (Rastegar [0033]).
