Office Action

§102 §103 §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 . Information Disclosure Statement The information disclosure statements filed 14 July 2023 fails to comply with 37 CFR 2. 1.98(a)(2), which requires a legible copy of each cited foreign patent document; each non- patent literature publication or that portion which caused it to be listed; and all other information or that portion which caused it to be listed. No copies were provided of the Foreign Patent Documents with the Cite. No. 3 EP 0400932 A3, Cite. No. 18 JP 2009504247 A, Cite. No. 24 WO 2011103669 A1, and Cite. No. 2 AU 2021290322 A1. Examiner suggests submitting copies of these documents and English translations of these documents if applicable. 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 11, 15-18, and 20-24 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. Claim 11 recites the limitation “wherein at least one of the first indentations, the second indentations, or the recesses are configured to detachably receive the orthodontic appliance or the two or more teeth, respectively” in lines 1-3. This limitation is unclear as it is unclear how the term “respectively” applies to the limitations, as there are three possible limitations which can be configured to detachably receive (the first indentations, the second indentations, or the recesses) but only two limitations which can be received (the orthodontic appliance or the two or more teeth). For purposes of examination, Examiner will interpret claim 11 line 3 as “two or more teeth, Claims 15 and 20-24 recite the limitation “the first groove”. This limitation is unclear as claim 13 recites the limitation “a plurality of first grooves” in line 9, and it is unclear if the limitation “the first groove” is intended to refer to one of the plurality of first grooves, all of the plurality of first grooves, or to another groove separate from the plurality of first grooves. For purposes of examination, Examiner will interpret the limitations claims 15 and 20-24 as “the first grooves”, referring to the plurality of first grooves, and suggests amending to clarify. Claims 16-18 and 20 recite the limitation “the second groove”. These limitation is unclear as claim 13 recites the limitation “a plurality of second grooves” in line 12, and it is unclear if the limitation “the second groove” is intended to refer to one of the plurality of second grooves, all of the plurality of second grooves, or to another groove separate from the plurality of second grooves. For purposes of examination, Examiner will interpret the limitations claims 16-18 and 20 as “the second grooves”, referring to the plurality of second grooves, and suggests amending to clarify. Claim 20 recites the limitation “wherein at least one of the first groove, the second groove, or the indentation is configured to detachably receive the orthodontic device or the two or more teeth, respectively” in lines 1-3. This limitation is unclear as it is unclear how the term “respectively” applies to the limitations, as there are three possible limitations which can be configured to detachably receive (the first groove, the second groove, or the indentation) but only two limitations which can be received (the orthodontic device or the two or more teeth). For purposes of examination, Examiner will interpret claim 11 line 3 as “two or more teeth, Claim Rejections - 35 USC § 102 The following is a quotation of the appropriate paragraphs of 35 U.S.C. 102 that form the basis for the rejections under this section made in this Office action: A person shall be entitled to a patent unless – (a)(1) the claimed invention was patented, described in a printed publication, or in public use, on sale, or otherwise available to the public before the effective filing date of the claimed invention.

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. Claims 11 and 20 are rejected under 35 U.S.C. 103 as being unpatentable over Lee in view of Doyle (U.S. Patent No. 5,863,198 A). In regard to claim 11, Lee discloses the invention of claim 8. Lee further discloses wherein the first indentations (1st indentations in annotated Fig. 10) are capable of detachably receiving the orthodontic appliance (Fig. 10, paras. 0042-0043). Lee does not disclose that it is via a snap fit arrangement. Doyle teaches an apparatus (20 in Fig. 2) for installing an orthodontic treatment device (Abstract) comprising first indentations (20d in Fig. 2) wherein the first indentations are capable of detachably receiving the orthodontic appliance via a snap fit arrangement (col. 4 lines 54-57). The references and the claimed invention are considered to be analogous to the claimed invention because they are in the same field of indirect bonding jigs. It would have been obvious to someone of ordinary skill in the art before the effective filing date of the claimed invention to have modified the first indentations of Lee by fabricating the first indentations so that the first indentations are capable of detachably receiving the orthodontic appliance via a snap fit arrangement as taught by Doyle in order to allow for the installation unit to securely engage the appliance while allowing the unit to be removed from the appliance with the application of a predetermined amount of force (col. 4 lines 57-61). In regard to claim 20, Lee discloses the invention of claim 13. Lee further discloses wherein the first grooves (1st indentations in annotated Fig. 10) are capable of detachably receiving the orthodontic device (Fig. 10, paras. 0042-0043). Lee does not disclose that it is via a snap fit arrangement. Doyle teaches an apparatus (20 in Fig. 2) for installing an orthodontic treatment device (Abstract) comprising a first groove (20d in Fig. 2) wherein the first groove is capable of detachably receiving the orthodontic device via a snap fit arrangement (col. 4 lines 54-57). The references and the claimed invention are considered to be analogous to the claimed invention because they are in the same field of indirect bonding jigs. It would have been obvious to someone of ordinary skill in the art before the effective filing date of the claimed invention to have modified the first grooves of Lee by fabricating the first grooves so that the first groove is capable of detachably receiving the orthodontic device via a snap fit arrangement as taught by Doyle in order to allow for the installation unit to securely engage the device while allowing the unit to be removed from the device with the application of a predetermined amount of force (col. 4 lines 57-61). Response to Arguments Applicant’s arguments filed 14 November 2025 with respect to the rejections of the claims have been considered but are moot because the new ground of rejection does not rely on any reference applied in the prior rejection of record for any teaching or matter specifically challenged in the argument. Applicant is directed to the rejections in view of the amendments. 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.
