Office Action

§102 §103 §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 . Priority Provisional application 63/225,660 filing date is 07/26/2021. Information Disclosure Statement The information disclosure statement (IDS) submitted on 1/24/2024 is being considered by the examiner. Election/Restrictions Applicant’s arguments in traversal of restriction filed 4/6/2024, have been fully considered and are persuasive. The restriction requirement has been withdrawn and all claims are examined herein on the merits. 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 1,3-11,13,16,18,24-26,28-32,34,36 and 39-42 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. Independent claims 1, 25, 26 and 40 recite “wherein the area indication . . . does not include coordinates and/or shapes that define a geographical area.” This negative limitation encompasses transmitting a large number of area indicators such as zip codes, geo-hashes, street addresses, states, etc. none of which are positively recited in the written specification. Thus this claim limitation encompasses subject matter which is lacking and not disclosed in a manner to be possessed by the inventors. Dependent claims 3-11,13,16,18,24,28-32,34,36,39, and 41-42 are rejected for the same reasons. Dependent Claims 4 and 29 are additionally rejected due to the language “the area indication is smaller than a geographical area configuration defined by a set of coordinates and/or shapes,” which raises a similar issue is it covers a wide variety of undisclosed area indication types that could be smaller than coordinates i.e. zip codes, area codes, name or abbreviation for a state, etc. 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 4 and 29 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. Claims 4 and 29 recite “the area indication is smaller than a geographical area configuration defined by a set of coordinates and/or shapes” which is indefinite because “a geographical area configuration defined by a set of coordinates and/or shapes” is not a fixed quantity and the size of which may vary greatly i.e. the size of a 1x1 tile versus a complicated shape. In any event the quantity is undefined and thus the claims are indefinite. 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. Claims 26, 29, 31-32, 34, and 40-41 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by US 9961524 B2 Suh; Kyung Joo et al. Claims 26 and 40.
