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 Claims 1, 6, and 11 objected to because of the following informalities: “electromagnetic radiation” in claim 1 line 14, claim 6 line 13, claim 11 line 17, respectively. It appears that “the” is missing. Appropriate corrections are required. Claims 5, 10, and 15-17 objected to because of the following informalities: “insertion loss” in claim 5 line 5, claim 10 line 4, claims 15-17 line 4, respectively. It appears that “the” is missing. Appropriate corrections are 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 1-20 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) “dimensions” in line 7. It is indefinite because it is not clear what the “dimensions” is of. And an antenna array is always in 3-dimensions in geometry. 2) "the geometry" in line 9. It is indefinite because it is not clear “the geometry” represents “a geometry for the antenna array” defined in lines 6-7 or “a geometry of the radome” defined in lines 8-9. 3) “dimensions” in line 9. It is indefinite because it is not clear what the “dimensions” is of and whether or not the “dimensions” in line 9 is the same as the “dimensions” in line 7. And a radome is always in 3-dimensions in geometry. 4) “the angles of incidence of electromagnetic radiation for a cell” in line 14. It is indefinite because it is not clear whether or not the “a cell” in line 14 relates to “each cell in the first set of discrete geometric and topological cells” mentioned in line 12 because “the angles of incidence of electromagnetic radiation” is determined “for each cell in the first set of discrete geometric and topological cells” as indicated in lines 12-13. 5) “that cell” in line 15.

Appropriate clarifications are required. Claim 6 recites the limitations: 1) “dimensions” in line 6. It is indefinite because it is not clear what the “dimensions” is of. And an antenna array is always in 3-dimensions in geometry. 2) "the geometry" in line 8.
