Office Action

§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 . Priority Receipt is acknowledged of certified copies of papers required by 37 CFR 1.55. Information Disclosure Statement The information disclosure statement (IDS) submitted on 8/22/2025 is in compliance with the provisions of 37 CFR 1.97. Accordingly, the information disclosure statement is being considered by the examiner. Claim Rejections - 35 USC § 112 The following is a quotation of the first paragraph of 35 U.S.C. 112(a): (a) IN GENERAL.—The specification shall contain a written description of the invention, and of the manner and process of making and using it, in such full, clear, concise, and exact terms as to enable any person skilled in the art to which it pertains, or with which it is most nearly connected, to make and use the same, and shall set forth the best mode contemplated by the inventor or joint inventor of carrying out the invention. The following is a quotation of the first paragraph of pre-AIA 35 U.S.C. 112: The specification shall contain a written description of the invention, and of the manner and process of making and using it, in such full, clear, concise, and exact terms as to enable any person skilled in the art to which it pertains, or with which it is most nearly connected, to make and use the same, and shall set forth the best mode contemplated by the inventor of carrying out his invention. Claims 1 and 3-6 are rejected under 35 U.S.C. 112(a) or 35 U.S.C. 112 (pre-AIA ), first paragraph, as failing to comply with the written description requirement. The claim(s) contains subject matter which was not described in the specification in such a way as to reasonably convey to one skilled in the relevant art that the inventor or a joint inventor, or for applications subject to pre-AIA 35 U.S.C. 112, the inventor(s), at the time the application was filed, had possession of the claimed invention. Claim 1 recites “step 7: identifying whether the types of each food image are the same, if yes, classifying semantic of each area and mark the category of each food image; if not, taking the food image as a new input, and returning to step 4”. However, nowhere in the specification describes in detail about the “identifying whether the types of each food image are the same, if yes, classifying semantic of each area and mark the category of each food image; if not, taking the food image as a new input, and returning to step 4”. It is also not clear as to what is being compared in this step. Although in Fig. 2 of the instant application shows the judging step; however, that step is to determine whether the accuracy of the classifier has been improved. Determining the accuracy of the classifier is not the same as determining the types of each food image are the same. As such, claim 1 includes subject matter that is not supported by the specification and fail to comply with the written description requirement. Claims 3-6 are rejected under this section because claims 3-6 are depend from claim 1. 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 1 and 3-6 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. Claim 1 recites the limitation "the target frame" in line 20. There is insufficient antecedent basis for this limitation in the claim. In addition, claim 1 recites “step 7: identifying whether the types of each food image are the same, if yes, classifying semantic of each area and mark the category of each food image; if not, taking the food image as a new input, and returning to step 4”. However, it is not clear as to what is being compared to determined “whether the types of each food image are the same”. In addition, it is not clear as to what is meant by “classifying semantic of each area”. Nowhere in the specification describes the details of step 7. Although Fig. 2 of the specification shows a determination step; however, that determination step is to determine whether the fusion step has any improvement. As such, claim 1 includes subject matter that is not clear and indefinite. Claims 3-6 are rejected under this section because they depend from claim 1. Conclusion The prior art made of record and not relied upon is considered pertinent to applicant's disclosure. Cho et al. (US 2019/0213416) discloses an electronic device and method for processing information associated with food and provide food intake recommendations. Yu et al. (US 2021/0166077) discloses a method for collecting photos of food items that is fed to augmented reality environment in an application that invokes a machine learning model to generate classification information for the photos. Ting et al. (US 9,449,029) discloses a method and system for diet management.
