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 listing of references in the specification in paragraphs 0065, 0075, 0089, and 0090 is not a proper information disclosure statement. 37 CFR 1.98(b) requires a list of all patents, publications, or other information submitted for consideration by the Office, and MPEP § 609.04(a) states, "the list may not be incorporated into the specification but must be submitted in a separate paper." Therefore, unless the references have been cited by the examiner on form PTO-892, they have not been considered. Drawings The drawings are objected to as failing to comply with 37 CFR 1.84(p)(5) because they include the following reference character(s) not mentioned in the description: “a” and “b” in Figure 6B. Corrected drawing sheets in compliance with 37 CFR 1.121(d), or amendment to the specification to add the reference character(s) in the description in compliance with 37 CFR 1.121(b) are required in reply to the Office action to avoid abandonment of the application. Any amended replacement drawing sheet should include all of the figures appearing on the immediate prior version of the sheet, even if only one figure is being amended. Each drawing sheet submitted after the filing date of an application must be labeled in the top margin as either “Replacement Sheet” or “New Sheet” pursuant to 37 CFR 1.121(d). If the changes are not accepted by the examiner, the applicant will be notified and informed of any required corrective action in the next Office action. The objection to the drawings will not be held in abeyance. Claim Objections Claims 12 and 13 are objected to because of the following informalities: Examiner suggests amending claim 12 line 2 to “[[a]]the single tooth aligner”. Examiner suggests amending claim 13 lines 1-2 to “lloop-shaped”. Appropriate correction is required. 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 5, 6, 12, 14, 16, and 18 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 5 recites the limitation "the recessed surface" in line 2. There is insufficient antecedent basis for this limitation in the claim as claims 1, 3, and 4 do not recite the limitation “a recessed surface”, though claim 3 lines 1-2 recites the limitation “a partial recessed surface”. For purposes of examination, Examiner will interpret claim 5 line 2 as, and suggests amending to, “the partial recessed surface”. Claim 6 recites the limitation "the recessed surface" in lines 1-2. There is insufficient antecedent basis for this limitation in the claim as claims 1, 3, and 4 do not recite the limitation “a recessed surface”, though claim 3 lines 1-2 recites the limitation “a partial recessed surface”. For purposes of examination, Examiner will interpret claim 6 lines 1-2 as, and suggests amending to, “the partial recessed surface”. Claim 12 recites the limitation “a loop-shaped connector” in line 1. It is unclear if the “a loop-shaped connector” of claim 12 line 1 is intended to refer to one of the two or more connectors of claim 11 line 2, or another connector which is unrelated to the two or more connectors. For purposes of examination, Examiner will interpret claim 12 line 1 as referring to one of the two or more connectors of claim 11 line 2 and suggests amending to clarify. Claim 14 recites the limitations "the distal end and the proximal end of the palatal arms" in line 2. There is insufficient antecedent basis for these limitations in the claim as claims 1, 3, and 7 do not recite the limitations “a distal end”, “a proximal end” or “palatal arms”. For purposes of examination, Examiner will interpret claim 14 line 2 as, and suggests amending to, “[[the]]a distal end and [[the]]a proximal end of [[the]] palatal arms”. Claim 16 recites the limitations “comprising one or more metal spacers the palatal portion has a thickness greater than thickness of the alignment portion”. The limitation is grammatically incorrect and it is unclear what the limitation is intending to claim, as the only mention of metal spacers is in para. 0179 of the Specification, which is grammatically incorrect in a similar way to claim 16. For purposes of examination, Examiner will interpret claim 16 as, “comprising one or more metal spacers, and wherein the palatal portion has a thickness greater than thickness of the alignment portion” and suggests amending to clarify. Claim 18 recites the limitation “in between sections of the buccal side” in line 2. This limitation is unclear as Applicant claims a unibody aligner in claim 1 line 2, and it is unclear what sections of the buccal side are being claimed as the aligner is a unibody. For purposes of examination, Examiner will interpret claim 18 line 2 as referring to sections with are an additional element to the unibody which is connected to the unibody, such as the single tooth aligner of claims 11-13, and suggests Applicant amend to clarify. The following is a quotation of 35 U.S.C. 112(d): (d) REFERENCE IN DEPENDENT FORMS.—Subject to subsection (e), a claim in dependent form shall contain a reference to a claim previously set forth and then specify a further limitation of the subject matter claimed. A claim in dependent form shall be construed to incorporate by reference all the limitations of the claim to which it refers. The following is a quotation of pre-AIA 35 U.S.C. 112, fourth paragraph: Subject to the following paragraph [i.e., the fifth paragraph of pre-AIA 35 U.S.C. 112], a claim in dependent form shall contain a reference to a claim previously set forth and then specify a further limitation of the subject matter claimed. A claim in dependent form shall be construed to incorporate by reference all the limitations of the claim to which it refers. Claim 20 is rejected under 35 U.S.C. 112(d) or pre-AIA 35 U.S.C. 112, 4th paragraph, as being of improper dependent form for failing to further limit the subject matter of the claim upon which it depends, or for failing to include all the limitations of the claim upon which it depends. Claim 20 is dependent on itself, as claim 20 recites “The dental appliance of claim 20” in line 1. For purposes of examination, Examiner will interpret claim 20 line 1 as “The dental appliance of claim [[20]]19” and suggests amending to clarify. Applicant may cancel the claim(s), amend the claim(s) to place the claim(s) in proper dependent form, rewrite the claim(s) in independent form, or present a sufficient showing that the dependent claim(s) complies with the statutory requirements. 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. Claims 1-4 and 6-7 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Riley et al (U.S. Publication No. 2018/0353264 A1, hereinafter “Riley).

In regard to claim 3, Riley discloses the invention of claim 1. Riley further discloses wherein the one or more retention sockets (110 in Figs. 1A-1C) have a partial recessed surface (surface in annotated Fig. 1B, Fig. 1C, para. 0067, recesses). In regard to claim 4, Riley discloses the invention of claim 3. Riley further discloses wherein the one or more retention sockets (110 in Figs. 1A-1C) are shaped to removably attach with a head of the implanted TAD (paras. 0008 and 0066-0068). In regard to claim 6, Riley discloses the invention of claim 4. Riley further discloses wherein the implanted TAD (TAD in Fig. 1B) has a head (paras. 0008, 0066 and 0068) and the partial recessed surface has a shape of a cylinder (Figs. 1A-1C, para. 0067). In regard to claim 7, Riley discloses the invention of claim 3. Riley further discloses wherein the palatal portion includes at least two retention sockets (110 in Figs. 1A-1C, three retention sockets in Fig. 1A, two shown in Fig. 1B and four shown in Fig. 4E). Claims 19 and 20 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Baughman et al (U.S. Patent No. 8,444,412 B2, hereinafter “Baughman”). PNG media_image2.png 332 607 media_image2.png Greyscale In regard to claim 19, Baughman discloses a dental appliance (Figs. 3-5b) comprising: an alignment portion (alignment portion in annotated Fig. 4a) shaped to fit over multiple teeth of a patient (Fig. 5a, col. 2 lines 65-66), the alignment portion having a buccal side (buccal side in annotated Fig. 4a) and a lingual side (lingual side in annotated Fig. 4a); and the buccal side having integrally formed portions (16 in Fig. 4a, col. 2 line 62- col. 3 line 7) capable of fitting over an implant (col. 3 lines 1-7). In regard to claim 20, Baughman discloses the invention of claim 19. Baughman further discloses wherein the implant comprises a temporary anchorage device (TAD) (12 in Figs. 3 and 5a, col. 2 lines 62-66). 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 5 is rejected under 35 U.S.C. 103 as being unpatentable over Riley in view of Baughman. In regard to claim 5, Riley discloses the invention of claim 4. Riley does not disclose wherein the implanted TAD has a spherical head and the partial recessed surface has a spherical shape, though Riley does disclose that the head of the TAD may be shaped in a variety of configurations (para. 0008). Baughman discloses a similar apparatus (Figs. 3-5b and 10c) comprising an implanted TAD (34 in Fig. 10c) and retention sockets having partially recessed surfaces (col. 3 lines 35-40, complimentary female mating portion), wherein the implanted TADs have a spherical head (Fig. 10c) and the partial recessed surfaces have a spherical shape (col. 3 lines 35-40, complimentary female mating portion). The references and the claimed invention are considered to be analogous to the claimed invention because they are in the same field of orthodontic aligner appliances coupled to implanted TADs. 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 implanted TAD and partial recessed surface of Riley by replacing the head of the implanted TAD with a spherical head and replacing the partial recessed surface to have a spherical shape as taught by Baughman in order to allow the aligner to be snap-fitted into place so as to be accurately positioned on the teeth and removable retained in the desired position (Baughman col. 1 lines 45-51). Claims 8 is rejected under 35 U.S.C. 103 as being unpatentable over Riley in view of Raby et al (U.S. Publication No. 2020/0253696 A1, hereinafter “Raby”). PNG media_image3.png 456 562 media_image3.png Greyscale In regard to claim 8, Riley discloses the invention of claim 1. Riley does not disclose further comprising: two or more palatal arms extending from the palatal portion, the palatal arms having a proximal end and a distal end, the proximal end being integrally formed with the palatal portion, and the distal end shaped to fit over a tooth of the patient. Raby teaches an apparatus (Figs. 1A-3) comprising a unibody aligner (10 in Fig. 1C) having a palatal portion (palatal portion in annotated Fig. 1C, para. 0052) comprising two or more palatal arms (16A and 16F in Fig. 1C, para. 0058) extending from the palatal portion (Fig. 1C), the palatal arms having a proximal end (proximal end in annotated Fig. 1C) and a distal end (distal end in annotated Fig. 1C), the proximal end being integrally formed with the palatal portion (para. 0054, integrally formed), and the distal end shaped to fit over a tooth of the patient (Fig. 1C, paras. 0036-0037). The references and the claimed invention are considered to be analogous to the claimed invention because they are in the same field of orthodontic shell appliances. 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 palatal portion of Riley by adding two or more palatal arms extending from the palatal portion, the palatal arms having a proximal end and a distal end, the proximal end being integrally formed with the palatal portion, and the distal end shaped to fit over a tooth of the patient as taught by Raby in order to allow for expansion in a horizontal plane as the arms relax from initial deflected states (Raby para. 0004). Claims 9-12 and 14-15 are rejected under 35 U.S.C. 103 as being unpatentable over Riley in view of Sato et al (U.S. Publication No, 2018/0368944 A1, hereinafter “Sato”). PNG media_image4.png 503 568 media_image4.png Greyscale In regard to claim 9, Riley discloses the invention of claim 1.

Moon teaches an apparatus (Fig. 1 and Fig. 2D, para. 0109) further comprising one or more double loops wires (Fig. 2D, para. 0108-0109) positioned in between sections of the buccal side (Figure 1, placed at Closing/Opening Loops 310). The references and the claimed invention are considered to be analogous to the claimed invention because they are in the same field of orthodontic shell appliances. 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 appliance of Riley by adding one or more double loops wires positioned in between sections of the buccal side as taught by Moon to allow for imparting controllability to the appliance and augmenting properties of the appliance to enhance effectiveness for realigning the teeth (Moon para. 0014).
