Office Action

§101 §112
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 . Patent Prosecution Highway Participation in the Patent Prosecution Highway (PPH) program between the Japan Patent Office (JPO) and the U.S. Patent and Trademark Office (USPTO) and petition under 37C.F.R. § 1.102(a) is acknowledged. Drawings Objections New corrected drawings in compliance with 37 CFR 1.121(d) are required in this application because figure 5 does not have any identification of the representation shown (X-Y axis). Applicant is advised to employ the services of a competent patent draftsperson outside the Office, as the U.S. Patent and Trademark Office no longer prepare new drawings. The corrected drawings are required in reply to the Office action to avoid abandonment of the application. The requirement for corrected drawings will not be held in abeyance. 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, 4-6 and 8-13 are rejected under 35 U.S.C. 101 because the claimed invention is directed to a judicial exception (i.e. “method of organizing human activity” which the court has identified as abstract) without significantly more. Claim 1 is directed to the abstract idea of inputting target feature data of a battery cell into a preset identification module and obtaining an identification result of whether the battery cell has experienced abnormal polarization; wherein the target feature data comprises a maximum target parameter value collected in a first stage of a formation process and/or a polarization elimination deviation of a target parameter in the first stage of the formation process. These limitations fall under method of organizing human activity. The claim does not include additional elements that are sufficient to amount to significantly more than the judicial exception. The claim as a whole does not amount to significantly more than the abstract idea itself. Claim 4 is directed to the abstract idea of inputting target feature data of a battery cell into a preset identification module and obtaining an identification result of whether the battery cell has experienced abnormal polarization: wherein the target feature data comprises: a target parameter value collected in a second stage of a formation process. These limitations fall under method of organizing human activity. The claim does not include additional elements that are sufficient to amount to significantly more than the judicial exception Claim 10 is directed to the abstract idea of inputting target feature data of a battery cell; into a preset identification module and obtaining an identification result of whether the battery cell has experienced abnormal polarization; wherein the target feature data comprises a maximum target parameter value collected in a first stage of a formation process and or a polarization elimination deviation of a target parameter in the first stage of the formation process. These limitations fall under method of organizing human activity. The claim does not include additional elements that are sufficient to amount to significantly more than the judicial exception because the only additional elements is an identification module, which is conventional or generic equipment which does not add anything significant to the judicial exception because this module is needed in order to input the data. Claim 13 is directed to the abstract idea of inputting target feature data of a battery cell into a preset identification module and obtaining an identification result of whether the battery cell has experienced abnormal polarization: wherein the target feature data comprises a target parameter value collected in a second stage of a formation process. These limitations fall under method of organizing human activity. The claim does not include additional elements that are sufficient to amount to significantly more than the judicial exception because the only additional elements is an identification module, which is conventional or generic equipment which does not add anything significant to the judicial exception because this module is needed in order to input the data. The generic data inputting is recited so generically (no details whatsoever are provided other than e.g., “inputting target feature data”) that it represents no more than mere instructions to apply the judicial exceptions on a computer. It can also be viewed as nothing more than an attempt to generally link the use of the judicial exceptions to the technological environment of a computer. Noting MPEP 2106.04(d)(I): “It is notable that mere physicality or tangibility of an additional element or elements is not a relevant consideration in Step 2A Prong Two. As the Supreme Court explained in Alice Corp., mere physical or tangible implementation of an exception does not guarantee eligibility. Alice Corp. Pty. Ltd. v. CLS Bank Int’l, 573 U.S. 208, 224, 110 USPQ2d 1976, 1983-84 (2014) ("The fact that a computer ‘necessarily exist[s] in the physical, rather than purely conceptual, realm,’ is beside the point")”. Thus, under Step 2A, prong 2 of the analysis, even when viewed in combination, these additional elements do not integrate the recited judicial exception into a practical application and the claims are directed to the judicial exception. No specific practical application is associated with the claimed method. For instance, nothing is done with the value collected. Under Step 2B, the claims do not include additional elements that are sufficient to amount to significantly more than the judicial exception because the additional elements, as described above, merely amount to a general purpose computer system that attempts to apply the abstract idea in a technological environment, no other details are claimed. Dependent claims 5-6, 8-9 and 11-12 merely expand upon the abstract idea further defining the abstract steps of claims 1, 4, 10 and 13 respectively, and therefore stand rejected under 35 USC 101 as being directed to non-statutory subject matter. Further, claim 12 is drawn to a "computer readable storage medium". The broadest reasonable interpretation of a claim drawn to a computer readable storage 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. The Examiner suggests that Applicant amend the claims as follows: "non-transitory computer readable storage medium…". 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. This application includes one or more claim limitations that do not use the word “means,” but are nonetheless being interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, because the claim limitation(s) uses a generic placeholder that is coupled with functional language without reciting sufficient structure to perform the recited function and the generic placeholder is not preceded by a structural modifier. Such claim limitation(s) is/are: a an identification module in claims 10 and 13. Because this/these claim limitation(s) is/are being interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, it/they is/are being interpreted to cover the corresponding structure described in the specification as performing the claimed function, and equivalents thereof. If applicant does not intend to have this/these limitation(s) interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, applicant may: (1) amend the claim limitation(s) to avoid it/them being interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph (e.g., by reciting sufficient structure to perform the claimed function); or (2) present a sufficient showing that the claim limitation(s) recite(s) sufficient structure to perform the claimed function so as to avoid it/them being interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph. Claim Rejections - 35 USC § 112 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. Claims 10 and 13 recite the limitations: “an identification module for inputting” which invokes 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph. However, the written description fails to disclose the corresponding structure, material, or acts for performing the entire claimed function and to clearly link the structure, material, or acts to the function. No association between the structure and the function can be found in the specification. Therefore, the claim is indefinite and is rejected under 35 U.S.C. 112(b) or pre-AIA 35 U.S.C. 112, second paragraph. Applicant may: (a) Amend the claim so that the claim limitation will no longer be interpreted as a limitation under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph; (b) Amend the written description of the specification such that it expressly recites what structure, material, or acts perform the entire claimed function, without introducing any new matter (35 U.S.C. 132(a)); or (c) Amend the written description of the specification such that it clearly links the structure, material, or acts disclosed therein to the function recited in the claim, without introducing any new matter (35 U.S.C. 132(a)). If applicant is of the opinion that the written description of the specification already implicitly or inherently discloses the corresponding structure, material, or acts and clearly links them to the function so that one of ordinary skill in the art would recognize what structure, material, or acts perform the claimed function, applicant should clarify the record by either: (a) Amending the written description of the specification such that it expressly recites the corresponding structure, material, or acts for performing the claimed function and clearly links or associates the structure, material, or acts to the claimed function, without introducing any new matter (35 U.S.C. 132(a)); or (b) Stating on the record what the corresponding structure, material, or acts, which are implicitly or inherently set forth in the written description of the specification, perform the claimed function. For more information, see 37 CFR 1.75(d) and MPEP §§ 608.01(o) and 2181. For the 112(b)/112(f) issues, Examiner suggests Applicant follow the USPTO policy on 35 U.S.C. 112(f) – “Means-plus-function” limitations http://www.uspto.gov/patent/laws-and-regulations/examination-policy/examination-guidance-and-training-materials, and recite that the modules are stored in memory and executed by a processor (following paragraphs ## of the Specification). This will overcome the 112(b) and 112(f) issues.
