Office Action

§101 §102 §112
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 Claims status Claims 1-14 are pending as the applicant filed on 11/01/2023. Claim Rejections - 35 USC § 112 2. 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. Claim 1-14 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. Regarding claims 1-14, the terms “maximum value” “similarity” “new similarity” “smaller” “gradually” “upper limit” “gradually narrowed down” “minimum value” are vague and a relative term that renders the claim indefinite. The terms “maximum value” “similarity” “new similarity” “smaller” “gradually” are not defined by the claim, the specification does not provide a standard for ascertaining the requisite degree, and one of ordinary skill in the art would not be reasonably appraised of the scope of the invention. An artisan doing measuring and testing would not know at what point “maximum value” “similarity” “new similarity” “smaller” “gradually” within the scope of the claim had been accomplished because nothing within the disclosure establishes when a sufficient “maximum value” “similarity” “new similarity” “smaller” “gradually” occur. Note: In view of the PTO compact prosecution, the Examiner notes that due to the indefiniteness issues described above all consideration of the merits of the claims in view of prior art is as best understood. 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 1-14 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. Claim 1, Step 1 the claim is a process (or machine) (Yes), Step 2A Prong One, does the claim recite an abstract idea? current claim related to a trajectory evaluation method performed by a trajectory evaluation apparatus comprising a processor, the trajectory evaluation method comprising: acquiring time series positioning data for a target and predetermined reference trajectory information; and mapping points representing the time series positioning data on a graph into corresponding points on a reference trajectory representing the predetermined reference trajectory information while relocating each mapped point onto a relocatable section taking into account a movable range dependent on a speed of the target appears is an abstract idea of mental process (MPEP 2106.04(a)) or data gathering equivalent to mathematical concept or mathematical manipulation function (MPEP 2106.04 (a) (2) (concept need not be expressed in mathematical symbols, because "[w]ords used in a claim operating on data to solve a problem can serve the same purpose as a formula), (OR Mathematical Concepts and Mental Processes) Step 2A Prong One: Yes. Step 2A Prong Two, is the claim directed to an abstract idea? In other words, does claim recite additional elements that integrate the Judicial Exception into a practical application? the additional elements of determining a maximum value of distances moved by the points while the points are mapped and relocated as a similarity between the time series positioning data and the reference trajectory are recited at a high level of generality and merely amount to a particular field of use (see MPEP 2106.05(h)) and/or insignificant post-solution activity (MPEP 2106.05(g)), this does not integrate the Judicial Exception into a practical application, Step 2A Prong Two: NO. Step 2B, Does the claim recite additional element that amount to significantly more than the Judicial exception? There is no more additional element. Step 2B: No. claim 1 not eligible. Claim 8, Step 1 the claim is a process (or machine) (Yes), Step 2A Prong One, does the claim recite an abstract idea? current claim related to a trajectory evaluation apparatus for evaluating a point sequence representing time series positioning data of a target by determining a similarity between the point sequence and a predetermined reference trajectory, comprising: a memory storing program instructions; and a processor coupled to the memory and executing the program instructions stored in the memory, wherein the program instructions, when executed by the processor, causes the processor to: acquire time series positioning data for a target and predetermined reference trajectory information; and map points representing the time series positioning data on a graph into corresponding points on a reference trajectory representing the predetermined reference trajectory information while relocating each mapped point onto a relocatable section taking into account a movable range dependent on a speed of the target appears is an abstract idea of mental process (MPEP 2106.04(a)) or data gathering equivalent to mathematical concept or mathematical manipulation function (MPEP 2106.04 (a) (2) (concept need not be expressed in mathematical symbols, because "[w]ords used in a claim operating on data to solve a problem can serve the same purpose as a formula), (OR Mathematical Concepts and Mental Processes) Step 2A Prong One: Yes.

Claims 8-14 are rejected under 35 U.S.C. 101 because the claimed invention is directed to non-statutory subject matter. The claims are drawn to a " a processor coupled to the memory and executing the program instructions stored in the memory". The broadest reasonable interpretation of a claim drawn to a computer readable medium covers forms of non-transitory tangible media and transitory propagating signals per se in view of the ordinary and customary meaning of computer readable media, particularly when the specification is silent (see MPEP 2111.01). Because the broadest reasonable interpretation covers a signal per se, a rejection under 35 USC 101 is appropriate as covering non-statutory subject matter. See 351 OG 212, Feb 23 2010. Claim Rejections - 35 USC § 102 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.
