Office Action

§101
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and the fee set forth in 37 CFR 1.17(e) has been timely paid, the finality of the previous Office action has been withdrawn pursuant to 37 CFR 1.114.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 1/29/26 has been entered. Claim Rejections - 35 USC § 101 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. Claims 1 and 3-10 are rejected under 35 U.S.C. 101 because the claimed invention is directed to a judicial exception (i.e., a law of nature, a natural phenomenon, or an abstract idea) without significantly more. Claims 1 and 3-10 are directed to an abstract idea without significantly more. The claims recite a mental process that can be performed by a human being and/or mathematical concepts and/or claim methods of image analysis. In regard to Claims 1 and 8, the following limitations can be performed as a mental process by a human being in terms of claiming collecting data, analyzing that data, and providing outputs based on that analysis which has been held by the CAFC to be an abstract idea in decisions such as, e.g., Electric Power Group, University of Florida Research Foundation, and Yousician v Ubisoft (non-precedential); and/or claim mathematical concepts as outlined at MPEP 2106.04(a)(2)(I); and/or claim methods of image analysis analogous to other methods of image analogous that have been held patent ineligible by the CAFC in decisions including Coffelt v. Nvidia (2017-1119; 3/15/17; non-precedential), Hawk Technology v Castle Retail (2022-1222; 2/17/2023), Mobile Acuity v. Blippar (2022-2216; 8/6/24), Recognicorp v. Nintendo (2016-1499; 4/28/17), Yu v. Apple (2020-1760; 6/11/21), in terms of the Applicant claiming: [a] method for [determining] an impact position on a club head of a golf club using [image data from] a first camera and a second camera operated in a stereoscopic manner […] the method comprising: acquiring [image data taken from] the first camera installed at a first location, [the] first image of a field of view including a golf ball and the golf club; acquiring [image data taken from] the second camera installed at a second location different from the first location, a second image of a field of view including the golf ball and the golf club; analyzing […] the first image to detect a position of a first ball which is a portion corresponding to the golf ball in the first image, and analyzing movement of the golf club on the first image to calculate a first club trajectory; analyzing […] the second image to detect a position of a second ball which is a portion corresponding to the golf ball in the second image. and analyzing movement of the golf club on the second image to calculate a second club trajectory; calculating […] a vertical distance from a center point of the first ball to the first club trajectory on the first image as a first ball distance; calculating […] a vertical distance from a center point of the second ball to the second club trajectory on the second image as a second ball distances; and calculating […] a point where a first position located at the first ball distance in a direction perpendicular to an optical axis of the first camera and a second position located at the second ball distance in a direction perpendicular to an optical axis of the second camera meet each other. as the impact position. In regard to the dependent claims, they also claim an abstract idea to the extent that they merely claim further limitations that likewise could be performed as a mental process by a human being and/or claim methods of image analysis. Furthermore, this judicial exception is not integrated into a practical application because to the extent that additional elements are claimed either alone or in combination such as, e.g., stereoscopic cameras and a processor executing Applicant’s abstract idea embodied as computer software; and/or a golf swing stage; these are merely claimed to add insignificant extra-solution activity to the judicial exception (e.g., data gathering), to embody the abstract idea on a general purpose computer, and/or do no more than generally link the use of a judicial exception to a particular technological environment or field of use. In this regard, see MPEP 2106.04(d)(I) in regard to “courts have also identified limitations that did not integrate a judicial exception into a practical application…” Furthermore, the claims do not include additional elements that taken individually, and also taken as an ordered combination, are sufficient to amount to significantly more than the judicial exception because to the extent that, e.g., stereoscopic cameras and a processor executing Applicant’s abstract idea embodied as computer software; and/or a golf swing stage; these are well-understood, routine, and conventional elements and are claimed for the well-understood, routine, and conventional functions of collecting and processing data and/or providing an analysis/outputs based on that processing. To the extent that an apparatus is claimed as an additional element said apparatus fails to qualify as a “particular machine” to the extent that it is claimed generally, merely implements the steps of Applicant’s claimed method, and is claimed merely for purposes of extra-solution activity or field of use. See MPEP 2106.05(b). As evidence that these additional elements are well-understood, routine, and conventional, Applicant’s specification discloses the support for these elements in a manner that indicates that the additional elements are sufficiently well-known that the specification does not need to describe the particulars of such additional elements to satisfy 35 U.S.C. § 112(a). See, e.g., F1-2 in Applicant’s PGPUB and text regarding same. Response to Arguments Applicant argues on page 9 of its Remarks in regard to the rejections made under 35 USC 101: PNG media_image1.png 200 706 media_image1.png Greyscale Applicant’s argument is not persuasive because Applicant’s claimed invention does not, in fact, improve the accuracy and/or precision of Applicant’s claimed stereoscopic cameras themselves, which would, in fact, be patent eligible under Thales. Instead, Applicant claim an ostensibly more accurate mathematical algorithm for analyzing images taken by those cameras, in order to identify moving objects in those images. Such improved mathematical algorithms, however, are not patent eligible under Mayo. See, e.g., from the CAFC’s decision in In re: Board of Trustees of the Leland Stanford Junior University (2020-1288; 3/25/21): PNG media_image2.png 162 476 media_image2.png Greyscale PNG media_image3.png 208 468 media_image3.png Greyscale Id., slip. op., pages 12-13. See also, in this regard, and specific to image analysis, from the CAFC’s decision in Coffelt v. Nvidia (2017-1119; 3/15/17): PNG media_image4.png 352 484 media_image4.png Greyscale Id., slip. op., page 3. Therefore, the rejections made under 35 USC 101 are maintained. Conclusion The prior art made of record and not relied upon is listed in the attached PTO-Form 892 and is considered pertinent to applicant's disclosure.
