Office Action

§112 §DOUBLEPATENT
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 STATUS Claims 1-18 were originally filed. Claims 1-18 were canceled by the preliminary amendment filed 06 March 2024. Claims 19-38 were newly added by the preliminary amendment filed 06 March 2024. Claims 19-38 are currently canceled. Claims 39-58 are newly added Claims 39-58 are currently pending and have been examined herein. INITIAL REMARKS Applicant is reminded that in order to be entitled to reconsideration or further examination, the Applicant or patent owner must reply to the Office action. The reply by the Applicant or patent owner must be reduced to a writing which distinctly and specifically points out the supposed errors in the examiner' s action and must reply to every ground of objection and rejection in the prior Office action. The reply must present arguments pointing out the specific distinctions believed to render the claims, including any newly presented claims, patentable over any applied references. If the reply is with respect to an application, a request may be made that objections or requirements as to form not necessary to further consideration of the claims, be held in abeyance until allowable subject matter is indicated. The Applicant's or patent owner's reply must appear throughout to be a bona fide attempt to advance the application or the reexamination proceeding to final action. A general allegation that the claims define a patentable invention without specifically pointing out how the language of the claims patentably distinguishes them from the references does not comply with the requirements of this section. Should the Applicant believe that a telephone conference would expedite the prosecution of the instant application, Applicant is invited to call the Examiner. RESPONSE TO ARGUMENTS While Applicant’s arguments are largely moot, in light of the cancelation of all of the previously pending claims, the Examiner is persuaded by the arguments regarding patentability over the prior art. However, the new scope of the claims still suffer from the deficiencies under §112 with respect to the feature of using a “predefined algorithm” and newly claimed “values derived therefrom”. More specifically as outlined below, Applicant has claimed a largely mathematical algorithm in a manner whereby the claimed scope far exceeds the level at which it is described in the Specification. Because mathematical type algorithms can be manipulated in an infinite number of configurations, by definition, they must be claimed in a manner that provides sufficient limits as to its scope. Here, while breadth does not automatically raise issues under §112, Applicant’s overly broad claims present written description/enablement issues as well as clarity issues, as outlined below. Accordingly, Applicant’s arguments are not persuasive. DOUBLE PATENTING The nonstatutory double patenting rejection is based on a judicially created doctrine grounded in public policy (a policy reflected in the statute) so as to prevent the unjustified or improper timewise extension of the “right to exclude” granted by a patent and to prevent possible harassment by multiple assignees. A nonstatutory double patenting rejection is appropriate where the conflicting claims are not identical, but at least one examined application claim is not patentably distinct from the reference claim(s) because the examined application claim is either anticipated by, or would have been obvious over, the reference claim(s). See, e.g., In re Berg, 140 F.3d 1428, 46 USPQ2d 1226 (Fed. Cir. 1998); In re Goodman, 11 F.3d 1046, 29 USPQ2d 2010 (Fed. Cir. 1993); In re Longi, 759 F.2d 887, 225 USPQ 645 (Fed. Cir. 1985); In re Van Ornum, 686 F.2d 937, 214 USPQ 761 (CCPA 1982); In re Vogel, 422 F.2d 438, 164 USPQ 619 (CCPA 1970); In re Thorington, 418 F.2d 528, 163 USPQ 644 (CCPA 1969). A timely filed terminal disclaimer in compliance with 37 CFR 1.321(c) or 1.321(d) may be used to overcome an actual or provisional rejection based on nonstatutory double patenting provided the reference application or patent either is shown to be commonly owned with the examined application, or claims an invention made as a result of activities undertaken within the scope of a joint research agreement. See MPEP § 717.02 for applications subject to examination under the first inventor to file provisions of the AIA as explained in MPEP § 2159. See MPEP § 2146 et seq. for applications not subject to examination under the first inventor to file provisions of the AIA . A terminal disclaimer must be signed in compliance with 37 CFR 1.321(b). The filing of a terminal disclaimer by itself is not a complete reply to a nonstatutory double patenting (NSDP) rejection. A complete reply requires that the terminal disclaimer be accompanied by a reply requesting reconsideration of the prior Office action. Even where the NSDP rejection is provisional the reply must be complete. See MPEP § 804, subsection I.B.1. For a reply to a non-final Office action, see 37 CFR 1.111(a). For a reply to final Office action, see 37 CFR 1.113(c). A request for reconsideration while not provided for in 37 CFR 1.113(c) may be filed after final for consideration. See MPEP §§ 706.07(e) and 714.13. The USPTO Internet website contains terminal disclaimer forms which may be used. Please visit www.uspto.gov/patent/patents-forms. The actual filing date of the application in which the form is filed determines what form (e.g., PTO/SB/25, PTO/SB/26, PTO/AIA /25, or PTO/AIA /26) should be used. A web-based eTerminal Disclaimer may be filled out completely online using web-screens. An eTerminal Disclaimer that meets all requirements is auto-processed and approved immediately upon submission. For more information about eTerminal Disclaimers, refer to www.uspto.gov/patents/apply/applying-online/eterminal-disclaimer. Claims 39-58 rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1-28 of U.S. Patent No. 11,797,043. Although the claims at issue are not identical, they are not patentably distinct from each other because they recite patentably indistinct features of the force sensor system. CLAIM REJECTIONS - 35 USC § 112 The following is a quotation of the first paragraph of 35 U.S.C. § 112(a): (a) IN GENERAL.—The specification shall contain a written description of the invention, and of the manner and process of making and using it, in such full, clear, concise, and exact terms as to enable any person skilled in the art to which it pertains, or with which it is most nearly connected, to make and use the same, and shall set forth the best mode contemplated by the inventor or joint inventor of carrying out the invention. Claims 39-58 are rejected under 35 U.S.C. § 112(a) or 35 U.S.C. § 112 (pre-AIA ), first paragraph, for failing to disclose a sufficient algorithm to satisfy the written description requirement, commensurate with the scope of the claimed invention. Re claim 39, Applicant’s recitation does not comply with the written description requirement because it sets forth a computer-implemented feature without an algorithm disclosed for achieving the particular computer-implemented feature commensurate with the scope of the claimed invention (i.e., enabled for the full scope of the claimed invention). This rejection applies regardless of whether § 112(f) is invoked.1 Particularly, claim 39 recites the following computer-implemented feature: “a processing circuit configured for determining at least two physical quantities related to a position of the magnet using a predefined algorithm receives the measured at least three magnetic field components, or values derived therefrom, as inputs…” Applicant is respectfully reminded, for computer-implemented claims, “examiners should determine whether the specification discloses the computer and the algorithm (e.g., the necessary steps and/or flowcharts) that perform the claimed function in sufficient detail such that one of ordinary skill in the art can reasonably conclude that the inventor invented the claimed subject matter.” MPEP § 2161.01(I). Applicant’s specification does not describe an algorithm that performs this feature in sufficient detail such that one of ordinary skill in the art can reasonably conclude that the inventor invented the claimed subject matter. Applicant’s specification even explicitly states that “the skilled person, having the benefit of the present disclosure, can easily find a suitable algorithm that meets his needs…” (emphasis added). However, such disclosure is not an algorithm (e.g., the necessary steps and/or flowcharts) that performs the claimed feature in sufficient detail such that one of ordinary skill in the art can reasonably conclude that the inventor invented the claimed subject matter. Applicant is also reminded, “[i]f the specification does not provide a disclosure of the computer and algorithm in sufficient detail to demonstrate to one of ordinary skill in the art that the inventor possessed the invention including how to program the disclosed computer to perform the claimed function, a rejection under 35 USC 112(a) or pre-AIA 35 USC 112, first paragraph, for lack of written description must be made.” MPEP § 2161.01(I). Therefore, because an algorithm for the computer-implemented feature is not disclosed in sufficient detail such that one of ordinary skill in the art can reasonably conclude that the inventor invented the claimed subject matter, and in accordance with MPEP § 2161.01, claim 19 is rejected for lack of written description. Dependent claims 40-52 fail to cure this deficiency of independent claim 39 (set forth directly above) and are rejected accordingly. Claims 53-58 contain language similar to claims 39-52 as discussed in the preceding paragraphs, and for reasons similar to those discussed above, claims 53-58 are also rejected under 35 USC § 112(a) as failing to comply with the written description requirement. 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. Claims 39-58 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. Re claim 39, Applicant recites the feature, “using a predefined algorithm…values derived therefrom”. However, such limitation represents a mathematical calculation that may be executed in any number of manners, as implied by the Specification. As such, one of ordinary skill in the art would not be reasonably apprised of the scope of this limitation, thereby rendering it indefinite. Further re claims 40-52, Applicant recites limitations respectively dependent from claim 39, but that fail to cure the deficiencies discussed in the rejection above. Accordingly, claims 40-52 are rejected based at least on the same reasons applied to claim 19 directly above. CONCLUSION Applicant's amendment necessitated the new ground(s) of rejection presented in this Office action. Accordingly, THIS ACTION IS MADE FINAL. See MPEP § 706.07(a). Applicant is reminded of the extension of time policy as set forth in 37 CFR 1.136(a). A shortened statutory period for reply to this final action is set to expire THREE MONTHS from the mailing date of this action. In the event a first reply is filed within TWO MONTHS of the mailing date of this final action and the advisory action is not mailed until after the end of the THREE-MONTH shortened statutory period, then the shortened statutory period will expire on the date the advisory action is mailed, and any extension fee pursuant to 37 CFR 1.136(a) will be calculated from the mailing date of the advisory action. In no event, however, will the statutory period for reply expire later than SIX MONTHS from the date of this final action.

Respectfully, /Thomas M Hammond III/Primary Examiner, GAU 2855 1 This rejection does not rely on 35 USC § 112(f) being invoked. See MPEP § 2161.01 (“[C]laims with computer-implemented functional claim limitations may invoke 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph. […]. Even if a claim is not construed as a means-plus-function limitation under 35 U.S.C. 112(f), computer-implemented functional claim language must still be evaluated for sufficient disclosure under the written description and enablement requirements of 35 U.S.C. 112(a).” (emphasis added)).
