Office Action

§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 . DETAILED ACTION Continued Examination Under 37 CFR 1.114 A request for continued examination under 37 CFR 1.114, including the fee set forth in 37 CFR 1.17(e), was filed in this application after final rejection. Since this application is eligible for continued examination under 37 CFR 1.114, and the fee set forth in 37 CFR 1.17(e) has been timely paid, the finality of the previous Office action has been withdrawn pursuant to 37 CFR 1.114. Applicant's submission has been entered. 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 14-15, 17-20, 23 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. The claims recite “generating, by the hardware processor and for image output, a second representation”, then “causing an additive manufacturing machine to build the 3D object based on the second representation”. There is inconsistency in the claim language since the second representation is generated for image output, but is then used for additive manufacturing which is not image output. At [0017] of Applicants specification it reads “The second representation of the 3D object can be used for image output, such as a display of the 3D object in a display device or a building of the 3D object by an additive manufacturing machine.” Which indicates image output or additive manufacturing is end result, not both. Therefore the scope of the claims is not readily ascertainable. The term “approximately” in claims 7, 17, 21 is a relative term which renders the claim indefinite. The term “approximately” is not defined by the claim, the specification does not provide a standard for ascertaining the requisite degree, and one of ordinary skill in the art would not be reasonably apprised of the scope of the invention. The claim recites “an approximately disc-shaped region” where the only recitation in the specification is at [0048] which recites “a region being grown can approximately be shaped as a disc” where no range or guidance is provided. Allowable Subject Matter Claims 1, 3-7, 9-15, 17-23 overcome the prior art however claims 7, 14-15, 17-20, 21, and 23 are rejected under 112(b) above.
