Office Action

§101
DETAILED ACTION The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA . This application currently names joint inventors. In considering patentability of the claims the examiner presumes that the subject matter of the various claims was commonly owned as of the effective filing date of the claimed invention(s) absent any evidence to the contrary. Applicant is advised of the obligation under 37 CFR 1.56 to point out the inventor and effective filing dates of each claim that was not commonly owned as of the effective filing date of the later invention in order for the examiner to consider the applicability of 35 U.S.C. 102(b)(2)(C) for any potential 35 U.S.C. 102(a)(2) prior art against the later invention. Election/Restrictions Claims 1-11 are withdrawn from further consideration pursuant to 37 CFR 1.142(b) as being drawn to a nonelected invention, there being no allowable generic or linking claim. Election was made without traverse in the reply filed on 20 April 2026. Claim Interpretation The following is a quotation of 35 U.S.C. 112(f): (f) Element in Claim for a Combination. – An element in a claim for a combination may be expressed as a means or step for performing a specified function without the recital of structure, material, or acts in support thereof, and such claim shall be construed to cover the corresponding structure, material, or acts described in the specification and equivalents thereof. The following is a quotation of pre-AIA 35 U.S.C. 112, sixth paragraph: An element in a claim for a combination may be expressed as a means or step for performing a specified function without the recital of structure, material, or acts in support thereof, and such claim shall be construed to cover the corresponding structure, material, or acts described in the specification and equivalents thereof. The claims in this application are given their broadest reasonable interpretation using the plain meaning of the claim language in light of the specification as it would be understood by one of ordinary skill in the art. The broadest reasonable interpretation of a claim element (also commonly referred to as a claim limitation) is limited by the description in the specification when 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, is invoked. As explained in MPEP § 2181, subsection I, claim limitations that meet the following three-prong test will be interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph: (A) the claim limitation uses the term “means” or “step” or a term used as a substitute for “means” that is a generic placeholder (also called a nonce term or a non-structural term having no specific structural meaning) for performing the claimed function; (B) the term “means” or “step” or the generic placeholder is modified by functional language, typically, but not always linked by the transition word “for” (e.g., “means for”) or another linking word or phrase, such as “configured to” or “so that”; and (C) the term “means” or “step” or the generic placeholder is not modified by sufficient structure, material, or acts for performing the claimed function. Use of the word “means” (or “step”) in a claim with functional language creates a rebuttable presumption that the claim limitation is to be treated in accordance with 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph. The presumption that the claim limitation is interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, is rebutted when the claim limitation recites sufficient structure, material, or acts to entirely perform the recited function. Absence of the word “means” (or “step”) in a claim creates a rebuttable presumption that the claim limitation is not to be treated in accordance with 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph. The presumption that the claim limitation is not interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, is rebutted when the claim limitation recites function without reciting sufficient structure, material or acts to entirely perform the recited function. Claim limitations in this application that use the word “means” (or “step”) are being interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, except as otherwise indicated in an Office action. Conversely, claim limitations in this application that do not use the word “means” (or “step”) are not being interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, except as otherwise indicated in an Office action. 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 12-19 are rejected under 35 U.S.C. 101 because the claimed invention is directed to an abstract idea without significantly more. The claim(s) recite(s) mental processes. The steps of claim 12 are for generating a look-up table, based on receiving information, having existing information, making determinations about the different types of information, and grouping, categorizing and selecting based on the information, where the result of the steps is an arrangement of information. This amounts to mental processes (see MPEP § 2106.04(a)(2)(III)). The steps could be performed by a person on paper or using a generic computer as a tool to perform the mental processes. The abstract idea is not integrated into a practical application because specifying that the information is of particular types, i.e., errors and compensations, is only generally linking the use of the judicial exception to a particular technological environment or field of use. The claim(s) does/do not include additional elements or steps that are sufficient to amount to significantly more than the judicial exception because requiring that the information used in mental processes be of specific types does not result in adding an inventive concept to the judicial exception. Further, the method being performed by a processor coupled to memory is only using a generic computer as a tool and does not amount to a practical application or significantly more (see MPEP § 2106.04(a)(2)(III)(C)). Claim 13 recites additional steps for selecting and determining information and thus the analysis above applies to claim 13 as well. Claim 14 recites additional information types and thus the analysis above applies to claim 14 as well. Claims 15 and 16 are each directed to performing a mathematical calculation for the determining information of claim 13 (see MPEP § 2106.04(a)(2)(I)(C)), and thus does not add a practical application or significantly more. Claim 17 is directed to the type of grouping of claim 12 and thus the analysis above for claim 12 applies to claim 17 as well. Claim 18 is directed to the type of grouping of claim 12 to performing subsequent mathematical calculations for groupings, and thus does not add a practical application or significantly more. Claim 19 is directed to performing mathematical calculations for the table, and thus does not add a practical application or significantly more. Conclusion The prior art made of record and not relied upon is considered pertinent to applicant's disclosure: Related inventorship PDLUT pre-compensation – US Patent Application Publication No. 2022/0239407. Other implementations of look-up table pre-compensation – US Patent Application Publication Nos. 2019/0149393, 2012/0081780, 2006/0024062; US Patent No. 12283996.
