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 . Claim Objections Claim 1 objected to because of the following informalities: “Computer-implemented method” in line 1. It appears that “a” is missing. Appropriate correction is required. Claims 2-5, 7-10 objected to because of the following informalities: “method” in line 1. It appears that “The” is missing. Appropriate correction is required. Claim 6 objected to because of the following informalities: 1) “method” in line 1. It appears that “a” is missing. 2) consistency of claimed language “N satellite radionavigation measurements” in line 3 and “the received measurements” in line 5, “the N measurements” in line 15. Appropriate corrections are required. Claim 10 objected to because of the following informalities: “the localization method” in line 3. It appears that “localization” should not be there. Appropriate correction is required. Claim 13 objected to because of the following informalities: “recorded a program” in line 1. It appears that it should be “a recorded program”. Appropriate correction is required. 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 1-13 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 limitations: 1) "the set" in line 9. It is indefinite because it is not clear which one of “a set of training data” in line 4, “each set of measurements” in line 7, “a set of metrics” in line 7, and “at least one set of residuals” in lines 7-8 "the set" in line 9 represent. 2) “a set of residuals” in line 16. It is indefinite because it is not clear whether or not the “a set of residuals” in line 16 is part of the “at least one set of residuals” mentioned in lines 7-8. 3) “residuals” in line 19. It is indefinite because: i) it is not clear what the “residuals” is about. ii) it is not clear which one of the “at least one set of residuals” mentioned in lines 7-8 and the “a set of residuals” mentioned in line 16 the “residuals” in line 19 relates to. Appropriate clarifications are required. Claims 2-13 are also rejected by virtue of their dependency on claim 1 because each of dependent claims 2-13 is unclear, at least, in that it depends on unclear independent claim 1. Claim 3 recites the limitation “the two systems” in line 4. There is insufficient antecedent basis for this limitation in the claim because “two systems” is not mentioned. Appropriate clarification is required. Regarding claim 4, the phrase "for example" renders the claim indefinite because it is unclear whether the limitation(s) following the phrase are part of the claimed invention. See MPEP § 2173.05(d). Appropriate clarification is required. Claim 5 recites the limitation “the received signal” in line 3. There is insufficient antecedent basis for this limitation in the claim because “received signal” is not mentioned. Appropriate clarification is required. Claim 6 recites the limitations: 1) “measurements” in line 7. It is indefinite because it is not clear what the “measurements” are and whether or not the “measurements” in line 7 relates to “the received measurements” mentioned in line 5. 2) “the training method according to any one of the preceding claims” in lines 9-10. It is indefinite because: i) the claimed language is multiple dependency, which is not clear which claim “the training method according to”. ii) There is insufficient antecedent basis for this limitation in the claim because the “training method” is not mentioned. 3) “residuals” in line 15. It is indefinite because: i) it is not clear what the “residuals” is about. ii) it is not clear whether or not the “residuals” in line 15 relates to the “at least one set of residuals” mentioned in line 6. Appropriate clarifications are required. Claims 7-11 are also rejected by virtue of their dependency on claim 6 because each of dependent claims 7-11 is unclear, at least, in that it depends on unclear independent claim 6. Claim 7 recites the limitation “a receiver” in lines 2-3. It is indefinite because: i) it is not clear whether or not the “a receiver” in lines 2-3 is the “a satellite radionavigation receiver” mentioned in claim 6 line 1. ii) it is not clear what relationship between the “a satellite radionavigation receiver” mentioned in claim 6 line 1 and the “a receiver” in lines 2-3. Appropriate clarification is required. Claim 8 is also rejected by virtue of its dependency on claim 7 because dependent claim 8 is unclear, at least, in that it depends on unclear claim 7. Claim 8 recites the limitation “this” in line 2. It is indefinite because it is not clear what the “this” represents. Appropriate clarification is required. Claim 9 recites the limitation “a receiver” in line 3. It is indefinite because: i) it is not clear whether or not the “a receiver” in line 3 is the “a satellite radionavigation receiver” mentioned in claim 6 line 1. ii) it is not clear what relationship between the “a satellite radionavigation receiver” mentioned in claim 6 line 1 and the “a receiver” in line 3. Appropriate clarification is required. Claim 10 recites the limitation “the received signal” in line 2. There is insufficient antecedent basis for this limitation in the claim because “received signal” is not mentioned. Appropriate clarification is required.
