Office Action

§101
3DETAILED 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 . Response to Arguments Applicant's arguments filed on January 02, 2026 have been fully considered but they are not persuasive. With respect to claim 1-22, applicant argued that these claims should not be rejected with 35 U.S.C. 101, Examiner disagree with applicant’s arguments. As pointed out by applicant’s, the paragraphs 7 and 8 of filed specification disclose that “the existing optical string recognition system fails to read the string altogether in the preceding circumstance and do not return any characters” and the paragraph 9 of the filed specification disclose that “These approaches provide apparatus and systems that provide feedback to a user when a partial match is identified. This allows the user to adjust parameters of the optical string recognition system until a full match is identified.”, however, the claims 1-22 does not include the limitation “these approaches provide apparatus and systems that provide feedback to a user when a partial match is identified. This allows the user to adjust parameters of the optical string recognition system until a full match is identified” which applicant believes that it is the improvement of the existing optical string recognition system. Therefore, the 35 USC 101 rejection is maintained. 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 1-22 is rejected under 35 U.S.C. 101 because the claimed invention is directed to a Judicial Exception in the form of an Abstract Idea, without significantly more: Beginning with independent claim 1, a process claim, which recites: A method of identifying a match for a model string in an image, the method comprising: performing optical character recognition on the image to identify a candidate string, the candidate string including a plurality of candidate characters; determining a minimum edit cost between the candidate string and the model string, the model string including a plurality of model characters, the minimum edit cost representative of a cost of edit operations performed on the candidate string to satisfy characteristics of the model string, wherein the determining the minimum edit cost includes: responsive to determining that there is a missing or invalid candidate character at a character position in the candidate string with respect to a character position in the model string, determining the minimum edit cost using a special cost of an edit operation for identifying the missing or invalid candidate character in the candidate string; determining, based on the minimum edit cost, whether the candidate string is a match for the model string; and responsive to determining that the candidate string is a match for the model string, returning an output string corresponding to the minimum edit cost, wherein the returning the output string includes: returning, as the output string, a partial string corresponding to the candidate string that includes a label representing the missing or invalid character at the character position in the candidate string. The claim recites abstract ideas: A process that encompass a human performing the steps mentally with or without a physical aid in the form of the “returning” steps, with the “performing” step and “determining” steps being pre-solution acts of processing information which could be performed visually and/or mentally; and A method of organizing human behavior in the form of a social activity of following rules or instructions informing a person to perform the “performing” step and “determining” steps and the “returning” steps. These two abstract ideas will be considered together for analysis as a single abstract idea per MPEP 2106: PNG media_image1.png 468 1527 media_image1.png Greyscale This judicial exception is not integrated into a practical application because there are no recited additional elements that amount to a practical application, such as but no limited to the following as noted in MPEP 2106: PNG media_image2.png 453 1451 media_image2.png Greyscale The claim does not include additional elements that are sufficient to amount to significantly more than the judicial exception for the same reason: There are not additional elements other than the abstract idea. Independent claim 1 is merely a generic computer implementation of the abstract ideas and likewise do not amount to significantly more. See MPEP 2106: PNG media_image3.png 249 1434 media_image3.png Greyscale Independent claim 8, a process claim, which recites: A non-transitory computer-readable medium comprising computer program instructions executable by at least one computer processor that when executed by the at least one computer processor perform a method of identifying a match for a model string in an image, the method comprising: performing optical character recognition on the image to identify a candidate string, the candidate string including a plurality of candidate characters; determining a minimum edit cost between the candidate string and the model string, the model string including a plurality of model characters, the minimum edit cost representative of a cost of edit operations performed on the candidate string to satisfy characteristics of the model string, wherein the determining the minimum edit cost includes: responsive to determining that there is a missing or invalid candidate character at a character position in the candidate string with respect to a character position in the model string, determining the minimum edit cost using a special cost of an edit operation for identifying the missing or invalid candidate character in the candidate string; determining, based on the minimum edit cost, whether the candidate string is a match for the model string; and responsive to determining that the candidate string is a match for the model string, returning an output string corresponding to the minimum edit cost, wherein the returning the output string includes: returning, as the output string, a partial string corresponding to the candidate string that includes a label representing the missing or invalid character at the character position in the candidate string The claim recites abstract ideas: A process that encompass a human performing the steps mentally with or without a physical aid in the form of the “returning” steps, with the “performing” step and “determining” steps being pre-solution acts of processing information which could be performed visually and/or mentally; and A method of organizing human behavior in the form of a social activity of following rules or instructions informing a person to perform the “performing” step and “determining” steps and the “returning” steps.

Independent claim 8 is merely a generic computer implementation of the abstract ideas and likewise do not amount to significantly more. See MPEP 2106: PNG media_image3.png 249 1434 media_image3.png Greyscale Independent claim 15, a process claim, which recites: A method of identifying a match for a model string in an image, the method comprising: performing optical character recognition on the image to identify a candidate string, the candidate string including a plurality of candidate characters; determining a minimum edit cost between the candidate string and the model string, the model string including a plurality of model characters, the minimum edit cost representative of a cost of edit operations performed on the candidate string to satisfy characteristics of the model string, wherein the determining the minimum edit cost includes: responsive to determining that a character position in the model string is identified as optional, determining the minimum edit cost using a special insertion cost of an insert operation for inserting, at a character position in the candidate string, a skip character marker indicating that an optional character position of the model string was skipped; determining, based on the minimum edit cost, whether the candidate string is a match for the model string; and responsive to determining that the candidate string is a match for the model string, returning an output string corresponding to the minimum edit cost, wherein the returning the output string includes: returning, as the output string, a basic string corresponding to the candidate string. The claim recites abstract ideas: A process that encompass a human performing the steps mentally with or without a physical aid in the form of the “returning” steps, with the “performing” step and “determining” steps being pre-solution acts of processing information which could be performed visually and/or mentally; and A method of organizing human behavior in the form of a social activity of following rules or instructions informing a person to perform the “performing” step and “determining” steps and the “returning” steps.
