Office Action

§102
DETAILED ACTION 1. Claims 1-16 of application 18/875,928, filed on 17-December-2024, are presented for examination. The IDS received on the same date has been considered. The present application, filed on or after 16-March-2013, is being examined under the first inventor to file provisions of the AIA . Rejections under 35 U.S.C. § 112(b) 2.1 The following is a quotation of 35 U.S.C. 112(b): (b) 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. 2.2 As per MPEP § 2111.4, claim scope is not limited by claim language that suggests or makes optional but does not require steps to be performed, or by claim language that does not limit a claim to a particular structure. However, examples of claim language, although not exhaustive, that may raise a question as to the limiting effect of the language in a claim are: PNG media_image1.png 18 19 media_image1.png Greyscale (A) "adapted to" or "adapted for" clauses; PNG media_image1.png 18 19 media_image1.png Greyscale (B) "wherein" clauses; and PNG media_image1.png 18 19 media_image1.png Greyscale (C) "whereby" clauses. PNG media_image1.png 18 19 media_image1.png Greyscale The determination of whether each of these clauses is a limitation in a claim depends on the specific facts of the case. See, e.g., Griffin v. Bertina, 283 F.3d 1029, 1034, 62 USPQ2d 1431 (Fed. Cir. 2002) (finding that a "wherein" clause limited a process claim where the clause gave "meaning and purpose to the manipulative steps"). In In re Giannelli, 739 F.3d 1375, 1378, 109 USPQ2d 1333, 1336 (Fed. Cir. 2014), the court found that an "adapted to" clause limited a machine claim where "the written description makes clear that 'adapted to,' as used in the [patent] application, has a narrower meaning, viz., that the claimed machine is designed or constructed to be used as a rowing machine whereby a pulling force is exerted on the handles." In Hoffer v. Microsoft Corp., 405 F.3d 1326, 1329, 74 USPQ2d 1481, 1483 (Fed. Cir. 2005), the court held that when a "‘whereby’ clause states a condition that is material to patentability, it cannot be ignored in order to change the substance of the invention." Id. However, the court noted that a "‘whereby clause in a method claim is not given weight when it simply expresses the intended result of a process step positively recited.’" Id. (quoting Minton v. Nat’l Ass’n of Securities Dealers, Inc., 336 F.3d 1373, 1381, 67 USPQ2d 1614, 1620 (Fed. Cir. 2003)). 2.3 Claims 13-15 are rejected, because the phrase “adapted to” on lines 3, 6 and 7 of claim 13, line 2 of claim 14, and line 6 of claim 15, is optional language that does not further limit the claim to a particular structure. Amending the claims to say “configured to” would obviate the rejection. Claim Rejections under 35 U.S.C. § 102(a)(1) 3.1 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)(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. 3.2 Claims 1-16 are rejected under 35 U.S.C. § 102(a)(1) as being anticipated by Tanner et al, USP Publication 2005/0033555. 3.3 Tanner discloses: Claim 1: A method of repairing a continuous flow engine component providing a damage [¶0001], wherein the method contains the steps of comprising: identifying the continuous flow engine component based on a unique identifier [0007 (an interactive damaged blade disposition form generated by said computer system, where the disposition form includes data fields for entering blade identification information, damage type and blade damage dimensions); 0021 (The form includes identifying database fields 82, which are linked to the corresponding databases 52, for entering information to identify the machine serial number, customer name, machine size and other identifying information useful in determining the blades that have been damaged…the blade technician enters the blade part number (or numbers if multiple blades are damages) into a database fields 83 for the blade identifying information.)], retrieving inspection data of the continuous flow engine component from an inspection database containing data of a damage of the continuous flow engine component [0006 (the invention is a method for evaluating a damaged blade in a compressor or turbine using a computer system accessing a database of blade repair information, where the method includes: selecting a blade damage geometry category corresponding to the damage of the blade from a plurality of blade damage geometry categories); 0007 (a system for evaluating a damaged blade in a compressor or turbine having a computer system accessing a database of blade repair information; an interactive damaged blade disposition form generated by said computer system, where the disposition form includes data fields for entering blade identification information, damage type and blade damage dimensions); 0015 (Damaged blades are generally detected when a turbine or compressor is stopped and opened for inspection.

The following prior art, discovered in an updated search and herein made of record, is considered pertinent to Applicant’s disclosure, and consists of document A on the attached PTO-892 Notice of References Cited: Document A defines a document of particular relevance, wherein the claimed invention cannot be considered novel or cannot be considered to involve an inventive step when the document is taken alone. Prior Art of Record 5. The Examiner has cited particular paragraphs or columns and line numbers in the references 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 specific limitations within the individual claim, other passages and figures may apply as well. It is respectfully requested of the applicant in preparing responses, to fully consider the references in their 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 prompt development of a clear issue requires that the replies of the Applicant meet the objections to and rejections of the claims. Applicant should also specifically point out the support for any amendments made to the disclosure (see MPEP §2163.06). Applicant is reminded that the Examiner is entitled to give the Broadest Reasonable Interpretation (BRI) of the language of the claims. Furthermore, the Examiner is not limited to Applicant’s definition which is not specifically set forth in the claims. [SEE MPEP 2141.02 [R-07.2015] VI. PRIOR ART MUST BE CONSIDERED IN ITS ENTIRETY, INCLUDING DISCLOSURES THAT TEACH AWAY FROM THE CLAIMS: A prior art reference must be considered in its entirety, i.e., as a whole, including portions that would lead away from the claimed invention. W.L. Gore & Associates, Inc. v. Garlock, Inc., 721 F.2d 1540, 220 USPQ 303 (Fed. Cir. 1983), cert, denied, 469 U.S. 851 (1984). See also MPEP §2123]. In addition, disclosures in a reference must be evaluated for what they would fairly teach one of ordinary skill in the art [See In re Snow, 471 F.2d 1400, 176 USPQ 328 (CCPA 1973) and In re Boe, 355 F.2d 961, 148 USPQ 507 (CCPA 1966)]. Specifically, in considering the teachings of a reference, it is proper to take into account not only the specific teachings of the reference, but also the inferences that one skilled in the art would reasonably have been expected to draw from the reference [See In re Freda, 401 F.2d 825, 159 USPQ 342 (CCPA 1968) and In re Shepard, 319 F.2d 194, 138 USPQ 148 (CCPA 1963)]. Likewise, it is proper to take into consideration not only the teachings of the prior art, but also the level of ordinary skill in the art [See In re Luck, 476 F.2d 650, 177 USPQ 523 (CCPA 1973)]. Specifically, those of ordinary skill in the art are presumed to have some knowledge of the art apart from what is expressly disclosed in the references [See In re Jacoby, 309 F.2d 513, 135 USPQ 317 (CCPA 1962)]. Response Guidelines 6.1 A shortened statutory period for response to this non-final action is set to expire 3 (three) months and 0 (zero) days from the date of this letter.
