Office Action

§101 §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 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 2-21 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. In claim 2, line 6, “the tooth that is different from the target position” has no prior antecedent basis. While there is antecedent basis for “a tooth”, there is no antecedent basis for a “tooth that is different from the target position”. It appears that “the tooth” should be –a tooth--. In claim 21, lines 8 and 9, “the tooth that is different from the target position” has no prior antecedent basis. While there is antecedent basis for “a tooth”, there is no antecedent basis for a “tooth that is different from the target position”. It appears that “the tooth” should be –a tooth--. Claim Rejections - 35 USC § 101 35 U.S.C. 101 reads as follows: Whoever invents or discovers any new and useful process, machine, manufacture, or composition of matter, or any new and useful improvement thereof, may obtain a patent therefor, subject to the conditions and requirements of this title. Claims 2-21 are rejected under 35 U.S.C. 101 because the claimed invention is directed to a judicial exception without significantly more. In accordance with MPEP 2106.04, this determination is based on the following analysis, in accordance with MPEP 2106.04 Step 2A, Prong 1 per MPEP 2106.04(a) Each of claims 2 and 12 recites at least one step or instruction for the step of determining, for one or more treatment stages, an overcorrected movement corresponding to an overcorrected position for the tooth that is different from the target position, wherein at least some of the one or more treatment stages include different magnitudes of overcorrected movements, which is grouped as a mental process in MPEP 2106.04(a)(2)(III). Accordingly, each of claims 2 and 12 recites an abstract idea. Further, dependent claims 3-11,13-21 merely include limitations that either further define the abstract idea (and thus don’t make the abstract idea any less abstract) or represent insignificant extra-solution activity or amount to no more than generally linking the use of the abstract idea to a particular technological environment or field of use because they’re merely incidental or token additions to the claims that do not alter or affect how the claimed functions/steps are performed. Accordingly, as indicated above, each of the above-identified claims recites an abstract idea as in MPEP 2106.04(a). Step 2A, Prong 2 per MPEP 2106.04(d) The above-identified abstract idea in each of independent claims 2 and 12 (and their respective dependent 3-11,13-21) is not integrated into a practical application under MPEP 2106.04(d) because the additional elements in independent claims 2 and 12, either alone or in combination, generally link the use of the above-identified abstract idea to a particular technological environment or field of use according to MPEP 2106.05(h) or represent insignificant extra-solution activity according to MPEP 2106.05(g). More specifically, the additional elements of a processor and memory storing instructions as recited in independent claim 12 and its dependent claims are generically recited computer elements which do not improve the functioning of a computer, or any other technology or technical field according to MPEP 2106.04(d)(1) and 2106.05(a). Similarly, the additional elements in claims 2 and 12 of receiving a plurality of treatment stages for repositioning a patient's teeth from an initial tooth arrangement toward a target tooth arrangement, wherein each treatment stage is associated with a target position for a tooth of the patient, and fabricating one or more dental appliances corresponding to the one or more treatment stages, each dental appliance including an overcorrected tooth receiving cavity corresponding to the overcorrected position for the respective treatment stage do not serve to apply the above-identified abstract idea with, or by use of, a particular machine according to MPEP 2106.05(b), effect a transformation according to MPEP 2106.05(c), provide a particular treatment or prophylaxis according to MPEP 2106.04(d)(2) or apply or use the above-identified abstract idea in some other meaningful way beyond generally linking the use thereof to a particular technological environment, such that the claim as a whole is more than a drafting effort designed to monopolize the exception according to MPEP 2106.04(d)(2) and 2106.05(e). Furthermore, the above-identified additional elements do not add a meaningful limitation to the abstract idea because they amount to simply implementing the abstract idea on a computer in accordance with MPEP 2106.05(f). For at least these reasons, the abstract idea identified above in independent claims 2 and 12 (and their respective dependent claims) is not integrated into a practical application in accordance with MPEP 2106.04(d). Moreover, the above-identified abstract idea is not integrated into a practical application in accordance with MPEP 2106.04(d) because the claimed method and system merely implements the above-identified abstract idea using rules (e.g., computer instructions) executed by a computer. In other words, these claims are merely directed to an abstract idea with additional generic computer elements which do not add a meaningful limitation to the abstract idea because they amount to simply implementing the abstract idea on a computer according to MPEP 2106.05(f). Thus, for these additional reasons, the abstract idea identified above in independent claims 2 and 12 (and their respective dependent claims) is not integrated into a practical application under MPEP 2106.04(d)(I). Accordingly, independent claims 2 and 12 (and their respective dependent claims) are each directed to an abstract idea according to MPEP 2106.04(d). Step 2B per MPEP 2106.05 None of claims 2-21 include additional elements that are sufficient to amount to significantly more than the abstract idea in accordance with MPEP 2106.05 for at least the following reasons. These claims require the additional elements of a processor and memory storing instructions. The above-identified additional elements are generically claimed computer components which enable the above-identified abstract idea(s) to be conducted by performing the basic functions of automating mental tasks. The courts have recognized such computer functions as well understood, routine, and conventional functions when claimed in a merely generic manner (e.g., at a high level of generality) or as insignificant extra-solution activity. See, MPEP 2106.05(d)(II) along with Versata Dev. Group, Inc. v. SAP Am., Inc., 793 F.3d 1306, 1334, 115 USPQ2d 1681, 1701 (Fed. Cir. 2015); and OIP Techs., 788 F.3d at 1363, 115 USPQ2d at 1092-93. Per Applicant’s specification, paragraphs 97 and 99, applicant describes the processor and memory storing instructions generically. Accordingly, in light of Applicant’s specification, these elements are reasonably construed as a generic computing device. Like SAP America vs Investpic, LLC (Federal Circuit 2018), it is clear, from the claims themselves and the specification, that these limitations require no improved computer resources, just already available technology, with their already available basic functions, to use as tools in executing the claimed process. See MPEP 2106.05(f). The recitation of the above-identified additional limitations in claims 2 and 12 amounts to mere instructions to implement the abstract idea on a computer. Simply using a computer or other machinery in its ordinary capacity for economic or other tasks (e.g., to receive, store, or transmit data) or simply adding a general-purpose computer or computer components after the fact to an abstract idea (e.g., a fundamental economic practice or mathematical equation) does not provide significantly more. See MPEP 2106.05(f) along with Affinity Labs v. DirecTV, 838 F.3d 1253, 1262, 120 USPQ2d 1201, 1207 (Fed. Cir. 2016) (cellular telephone); and TLI Communications LLC v. AV Auto, LLC, 823 F.3d 607, 613, 118 USPQ2d 1744, 1748 (Fed. Cir. 2016) (computer server and telephone unit). Moreover, implementing an abstract idea on a generic computer does not add significantly more, similar to how the recitation of the computer in the claim in Alice amounted to mere instructions to apply the abstract idea of intermediated settlement on a generic computer. For at least the above reasons, claims 2-21 are directed to applying an abstract idea as identified above on a general purpose computer without (i) improving the performance of the computer itself or providing a technical solution to a problem in a technical field according to MPEP 2106.05(a), or (ii) providing meaningful limitations to transform the abstract idea into a patent eligible application of the abstract idea such that these claims amount to significantly more than the abstract idea itself according to MPEP 2106.04(d)(2) and 2106.05(e). Furthermore, the additional limitation of “fabricating” does not provide more than an insignificant extra-solution activity. According to MPEP 2106.05(g), “The term "extra-solution activity" can be understood as activities incidental to the primary process or product that are merely a nominal or tangential addition to the claim. Extra-solution activity includes both pre-solution and post-solution activity.” Per MPEP 2106.05(g), the following factors may be considered in such determination: (1) Whether the extra-solution limitation is well known. See Bilski v. Kappos, 561 U.S. 593, 611-12, 95 USPQ2d 1001, 1010 (2010) (well-known random analysis techniques to establish the inputs of an equation were token extra-solution activity); Flook, 437 U.S. at 593-95, 198 USPQ at 197 (a formula would not be patentable by only indicating that is could be usefully applied to existing surveying techniques); Intellectual Ventures I LLC v. Erie Indem. Co., 850 F.3d 1315, 1328-29, 121 USPQ2d 1928, 1937 (Fed. Cir. 2017) (the use of a well-known XML tag to form an index was deemed token extra-solution activity). Because this overlaps with the well-understood, routine, conventional consideration, it should not be considered in the Step 2A Prong Two extra-solution activity analysis. (2) Whether the limitation is significant (i.e. it imposes meaningful limits on the claim such that it is not nominally or tangentially related to the invention). See Ultramercial, Inc. v. Hulu, LLC, 772 F.3d 709, 715-16, 112 USPQ2d 1750, 1755 (Fed. Cir. 2014) (restricting public access to media was found to be insignificant extra-solution activity); Apple, Inc. v. Ameranth, Inc., 842 F.3d 1229, 1242, 120 USPQ2d 1844, 1855 (Fed. Cir. 2016) (in patents regarding electronic menus, features related to types of ordering were found to be insignificant extra-solution activity). This is considered in Step 2A Prong Two and Step 2B. (3) Whether the limitation amounts to necessary data gathering and outputting, (i.e., all uses of the recited judicial exception require such data gathering or data output). See Mayo, 566 U.S. at 79, 101 USPQ2d at 1968; OIP Techs., Inc. v. Amazon.com, Inc., 788 F.3d 1359, 1363, 115 USPQ2d 1090, 1092-93 (Fed. Cir. 2015) (presenting offers and gathering statistics amounted to mere data gathering). This is considered in Step 2A Prong Two and Step 2B. In this case, the addition of the limitation “fabricating” appears to fail above test (1). It is well known to simply fabricated orthodontic appliances, once they have been designed. Accordingly, claims 2-21 are not patent eligible and rejected under 35 U.S.C. 101. Applicant's arguments filed 8/10/26 have been fully considered but they are not persuasive. Applicant’s arguments regarding the 112 2nd paragraph rejection have been considered, but are not found persuasive. The 112 rejection has been further clarified to specify that the particular recitation, as a whole, does not find antecedent basis. See above rejection. Applicant’s arguments regarding the 101 rejection have been considered, but are not found persuasive. Applicant argues that the addition of the limitation “fabricating”, now directs the claims to patentable subject matter. This is not found persuasive as such limitation does not provide for more than an insignificant extra-solution activity. See the modified grounds of rejection above, with reference to MPEP 2106.05(g). 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. 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.
