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 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 1-15 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. Applicant’s amendments introduce new matter, not originally disclosed, to the claims. The following recitations are not supported by the application, as originally filed: In claim 1, lines 6 and 7, “generate a plurality of intermediate 3D tooth reconstructions from successive subsets of the video and depth measurements”. In claim 2, lines 2 and 3, “configured to capture the continuous video at a frame rate sufficient to resolve tooth surface morphology changes during the relative motion.” In claim 3, lines 2-3, “frames used in generating intermediate 3D tooth reconstructions”. In claim 5, lines 2-4, “depth measurements synchronized with the continuous video for use in generating the intermediate 3D tooth reconstructions.” In claim 10, lines 2-4, “spatial alignment between the RGB camera and the depth sensor before generating the intermediate 3D tooth reconstructions.” In claim 13, lines 2-3, “configured to generate the intermediate 3D tooth reconstructions.” In claim 14, lines 3-4, “executed repeatedly on successive subsets of the continuous video and depth measurements”. All instances of new matter should be removed in response to this office action. Although no prior art rejection has been applied, applicant should note that a prior art rejection may be reapplied in a subsequent office action. Conclusion Applicant's amendment necessitated the new ground(s) of rejection presented in this Office action. Accordingly, THIS ACTION IS MADE FINAL. See MPEP § 706.07(a). Applicant is reminded of the extension of time policy as set forth in 37 CFR 1.136(a). A shortened statutory period for reply to this final action is set to expire THREE MONTHS from the mailing date of this action. In the event a first reply is filed within TWO MONTHS of the mailing date of this final action and the advisory action is not mailed until after the end of the THREE-MONTH shortened statutory period, then the shortened statutory period will expire on the date the advisory action is mailed, and any nonprovisional extension fee (37 CFR 1.17(a)) pursuant to 37 CFR 1.136(a) will be calculated from the mailing date of the advisory action. In no event, however, will the statutory period for reply expire later than SIX MONTHS from the mailing date of this final action.
