Office Action

§101 §102
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 . Continued Examination Under 37 CFR 1.114 A request for continued examination under 37 CFR 1.114, including the fee set forth in 37 CFR 1.17(e), was filed in this application after final rejection. Since this application is eligible for continued examination under 37 CFR 1.114, and the fee set forth in 37 CFR 1.17(e) has been timely paid, the finality of the previous Office action has been withdrawn pursuant to 37 CFR 1.114. Applicant's submission filed on December 31, 2024 has been entered. Accordingly, claims 1-18, 22, 23, 25, 26 and 35-38 are currently in cancelled status; claims 19-21, 24 and 27-34 are currently pending in the application. Response to Arguments Applicants’ arguments with respect to claims 19-21, 24 and 27-34 have been considered but are moot because the new ground of rejection does not rely on any reference applied in the prior rejection of record for any teaching or matter specifically challenged in the argument. Claim Objections Claim 21 is objected to because of the following informalities: one of the two appearances of “one or more said specialized pathways” in line 3 should be deleted. Appropriate correction is required. Claim Rejections - 35 USC § 101 and 35 USC § 112 35 U.S.C. 101 reads as follows: Whoever invents or discovers any new and useful process, machine, manufacture, or composition of matter, or any new and useful improvement thereof, may obtain a patent therefor, subject to the conditions and requirements of this title. 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. The following is a quotation of 35 U.S.C. 112 (pre-AIA ), second paragraph: The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the applicant regards as his invention. Claims 27-34 are rejected under 35 U.S.C. 5 101 and 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. The statutory categories under 35 U.S.C. 101 are expressed in the alternative, i.e., process, machine, manufacture or composition of matter (emphasis added). Thus, claims 27-34, which encompass two statutory categories, i.e., apparatus (a sensor) and method (method for monitoring a plurality of pathways), violate 35 U.S.C. 5 101. See Ex parte Lyell, 17 USPQ2d 1548, 1551 (Bd. Pat. App. & Int. 1990). Moreover, there are two separate requirements set forth in the second paragraph of 35 U.S.C. 112: (A) the claims must set forth the subject matter that applicants regard as their invention; and (B) the claims must particularly point out and distinctly define the metes and bounds of the subject matter that will be protected by the patent grant. It is unclear whether claims 27-34 claim an apparatus or a method. Claims 27-34, therefore, are indefinite in violation of 35 U.S.C. 112, second paragraph. See Lyell, 17 USPQ2d at 1552. With regard to claims 27-34, each claim a method, but these claims fail to set forth any steps involved in the method/process. In addition, it is unclear what method/process applicants are intending to encompass (“method for monitoring a plurality of pathways”, “a method of optimization according to exactness”, “a method of irregularity detection”, “a method of irregularity avoidance”, “a method of irregularity adaptation”, “a method of irregularity recognition”, “a method of irregularity acquisition”, or “a method of data optimization according to reliability”). With regard to claims 28-34, each of these claims recites two different methods, which are a “method for monitoring a plurality of pathways” and one of the following methods (“a method of optimization according to exactness”, “a method of irregularity detection”, “a method of irregularity avoidance”, “a method of irregularity adaptation”, “a method of irregularity recognition”, “a method of irregularity acquisition”, or “a method of data optimization according to reliability”). It is not clear what method the phrase “the method comprising” in line 1 of each claim refers to. There is a lack of antecedent basis in each claim. A claim is indefinite where it merely recites a use without any active, positive steps delimiting how this use is actually practiced. Without setting forth any steps involved in the process results in an improper definition of a process, i.e., results in a claim which is not a proper process claim under 35 U.S.C. 101. Applicants are advised to follow a proper method claim format that conforms to current U.S. practice (For example, “A method for/of .... comprising steps of:” and a series of active, positive steps involved in the process) (emphasis added). The essential purpose of patent examination is to determine whether or not the claims are precise, clear, correct, and unambiguous to ensure that the scope of the claims is clear so the public is informed of the boundaries of what constitutes infringement of the patent. Therefore, the uncertainties of claim scope should be removed as much as possible. The applicants are advised to follow the claim format in the proposed claim amendment as discussed in the telephonic interview on March 7, 2025 and in the claim section of the references cited below as guidance. Claim Interpretation Claims 27-34 presents a device according to the capacitive displacement sensor of claims 19-21, 24. Therefore, the argument made against claims 19-21, 24 also applies, mutatis mutandis, to claims 27-34. 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 19, 21 and 27 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Andermo (US 5,731,707 A).
