Office Action

§102 §103
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 Acknowledgment is made of applicant’s claim for domestic priority under 35 U.S.C. 119 (e)). For the purpose of examination, the priority date for claims 1-7, 10-20, 26-27, and 44-46 is 12/15/2022. Claim Objections Claim 20 is objected to because of the following informalities: Claim 20 recites the limitation "wherein outputting further comprises transforming [[the]] a stage of the plurality of stages" in lines 1-2. There is insufficient antecedent basis for this limitation in the claim, as claims 14 and 19, which claim 20 depends on, do not recite a method step of “outputting”. For examination purposes, Examiner is interpreting the claim as “wherein a step of outputting further comprises transforming [[the]] a stage of the plurality of stages”.. Appropriate correction is required.

Claim Rejections - 35 USC § 103 The following is a quotation of 35 U.S.C. 103 which forms the basis for all obviousness rejections set forth in this Office action: A patent for a claimed invention may not be obtained, notwithstanding that the claimed invention is not identically disclosed as set forth in section 102, if the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to which the claimed invention pertains. Patentability shall not be negated by the manner in which the invention was made. Claim(s) 8 and 21 is/are rejected under 35 U.S.C. 103 as being unpatentable over Wu et al. (US 20100151404 A1), herein referred to as Wu, in view of Claessen et al. (US 20210174543 A1), herein referred to as Claessen. Regarding claim 8, Wu discloses the method of claim 1, but is silent to confirming the mapped reference points of the matched pair are not in a line. Claessen discloses a method for automated superimposition of objects in the same field of endeavor (refer to Paragraphs [0002], [0006]). The method comprises matching pairs of teeth in two dental models based on surface reference points (refer to Paragraphs [0150], [0154] and Figs. 10A-10B; the CBCT and intraoral 3D scans are matched by key points) and generating a tooth-to-crown transformation between the models (refer to Paragraph [0154]; a set of transformation parameters for each matching tooth set is determined), wherein the generation of the tooth-to-crown transformation further comprises confirming that the one or more reference points mapped are not in a line (refer to Paragraph [0155]; at least three non-colinear points need to be determined for alignment transformation parameters). It would have been obvious to one having ordinary skill in the art before the effective filing date of the claimed invention to have modified the method of Wu with confirming the reference points are not colinear as taught by Claessen in order to determine alignment transformation parameters between the two dental models. Regarding claim 21, Wu discloses the system Claessen discloses a method for automated superimposition of objects in the same field of endeavor (refer to Paragraphs [0002], [0006]). The method comprises matching pairs of teeth in two dental models based on surface reference points (refer to Paragraphs [0150], [0154] and Figs. 10A-10B; the CBCT and intraoral 3D scans are matched by key points) and generating a tooth-to-crown transformation between the models (refer to Paragraph [0154]; a set of transformation parameters for each matching tooth set is determined), wherein the generation of the tooth-to-crown transformation further comprises confirming that the one or more reference points mapped are not in a line (refer to Paragraph [0155]; at least three non-colinear points need to be determined for alignment transformation parameters). It would have been obvious to one having ordinary skill in the art before the effective filing date of the claimed invention to have modified the method executed by the system (2400) of Wu with confirming the reference points are not colinear as taught by Claessen in order to determine alignment transformation parameters between the two dental models. Claim(s) 9 and 22 is/are rejected under 35 U.S.C. 103 as being unpatentable over Wu et al. (US 20100151404 A1), herein referred to as Wu, in view of Cai et al. (US 20160175068 A1), herein referred to as Cai. Regarding claim 9, Wu discloses the method of claim 1, but is silent to the number of matching pairs being greater than three. Cai discloses a method of generating tooth arrangements in the same field of endeavor (refer to Paragraph [0002]). Similar to Applicant’s method, the method of Cai includes selecting a group of digital models that represents the best tooth arrangement with an optimization model (refer to Paragraphs [0007], [0010]), wherein one of the parameters of the model is the curve of a dental arch (refer to Paragraph [0012]. The model of the dental arch is created using four reference points (refer to Paragraph [0109]). It would have been obvious to one having ordinary skill in the art before the effective filing date of the claimed invention to have modified the pair matching method of Wu to include a minimum of four reference points, as Cai demonstrates that a best fit model for a tooth arrangement can be generated using four reference points, the same purpose of Applicant’s method. Regarding claim 22, Wu discloses the method of claim 1, but is silent to the number of matching pairs being greater than three. Cai discloses a method of generating tooth arrangements in the same field of endeavor (refer to Paragraph [0002]). Similar to Applicant’s method, the method of Cai includes selecting a group of digital models that represents the best tooth arrangement with an optimization model (refer to Paragraphs [0007], [0010]), wherein one of the parameters of the model is the curve of a dental arch (refer to Paragraph [0012]. The model of the dental arch is created using four reference points (refer to Paragraph [0109]). It would have been obvious to one having ordinary skill in the art before the effective filing date of the claimed invention to have modified the pair matching method as executed by the system (2400) of Wu to include a minimum of four reference points, as Cai demonstrates that a best fit model for a tooth arrangement can be generated using four reference points, the same purpose of Applicant’s method. Response to Arguments The outstanding claim objections of claims 7, and 14-27 are withdrawn in view of the newly submitted claim amendments. The outstanding drawing and specification objections are withdrawn in view of the newly submitted drawing and specification amendments. The outstanding 35 U.S.C. 101 rejection is withdrawn in view of the submitted claim amendments to include a fabrication step. Applicant's arguments filed 11/18/2025 have been fully considered but they are not persuasive. Regarding the argument that Wu does not teach transforming a surface of one or more teeth of the best matched digital model in accordance with the surface characteristics of the one or more teeth of the current digital model, Examiner points to Paragraphs [0076], [0164]-[0165] of Wu. Wu teaches using points on the surface of teeth of a planning model with an ICP surface algorithm to generate a new, transformed model, based on a rigid body transform generated from the tracking, or current model. Further, this new, transformed model, is subsequently used for comparison to the planned model for creation of a revised treatment plan, with the new, transformed model, acting as the initial arrangement for the revised treatment plan (refer to Paragraphs [0052], [0071], [0165], [0234], Fig. 24C). These arguments follow for the rejection of claims 8, 9, 21 and 22 which rely on a combination of Wu in view of Claessen and Wu in view of Cai. Conclusion THIS ACTION IS MADE FINAL. 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.
