Office Action

§102 §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 1-15 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 1 and Claim 15 both recite “a dental appliance” in line 1 and “an appliance” in line 3. It is unclear if these are meant to refer to the same appliance or a different appliance. Claim 1 and 15 also both recite “a cavity for accommodating an unerupted or erupting tooth” in line 1 and “a cavity for accommodating an unerupted or erupting tooth” in line 5. Similarly, it is unclear if these are meant to refer to the same cavity or a different cavity. 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 1-15 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Kitching (US 2008/0294405). Kitching shows a dental appliance having a cavity for accommodating an unerupted or erupting tooth ([0107]), comprising an appliance designed to implement at least a portion of a treatment plan (Fig. 7), comprising a shell having a plurality of cavities therein designed to receive teeth of a jaw (shell teeth of 710) with at least one of the plurality of cavities being a cavity for accommodating an unerupted or erupting tooth therein (at 768; [0106]-[0107]), wherein at least one of a size, shape, location, and orientation of at least one of the cavities for accommodating an unerupted or erupting tooth are based upon a prediction of at least one of a size, shape, location, or orientation of the unerupted or erupting tooth (this is considered product-by-process where only the resulting structure of an appliance with cavities for the teeth and unerupted teeth are provided; however, Kitching shows this by having the shell 710 having a space 768 for accommodating the predicted virtual fully erupted tooth 741). With respect to claim 2, wherein the cavities for accommodating an unerupted or erupting tooth include a gingival edge (at bottom portion of 710 that will run along gingiva) and wherein the gingival edge is oriented and shaped based upon a prediction of at least one of the orientation and shape of the gingiva that will be adjacent to the gingival edge (this is again considered product-by-process, however Kitching discusses this in [0106]). With respect to claim 3, wherein the cavities for accommodating an unerupted or erupting tooth each differ in at least one of: size, shape, location, or orientation (aside from each cavity for a different tooth needing to be in a different location, [0091] discusses generation based on different factors). With respect to claim 4, wherein the cavities for accommodating an unerupted or erupting tooth have at least one characteristic of: size, shape, location, or orientation based on data representing the unerupted or erupting teeth in multiple states of eruption that is based upon one or more tooth eruption prediction factors of at least one fully erupted tooth of a patient (this is considered product-by-process where only the resulting structure of an appliance with cavities for the teeth and unerupted teeth are provided as detailed above). With respect to claim 5, wherein the cavities for accommodating an unerupted or erupting tooth have at least one characteristic of: size, shape, location, or orientation based on data including at least one of: a size, shape, location, and orientation of a tooth adjacent, opposing or of a same type of tooth to the unerupted or erupting tooth (this is considered product-by-process where only the resulting structure of an appliance with cavities for the teeth and unerupted teeth are provided as detailed above). With respect to claim 6, further wherein the cavity configured to accommodate the unerupted or erupting tooth is sized in part based on a scaling factor for a first projected dimension of a cavity for accommodating the unerupted or erupting tooth as the tooth erupts (this is considered product-by-process where only the resulting structure of an appliance with cavities for the teeth and unerupted teeth are provided as detailed above). Apparatus claims 7-15 are rejected similarly to the above as they have the same limitations. Additionally, with respect to claim 8, wherein the scaled first projected dimension is scaled using a scaling factor based on a calculation of available space in a corresponding dimension around the unerupted or erupting tooth and sized such that the unerupted or erupting tooth will not contact a surface of the cavity as the tooth erupts during a period of treatment (this is considered product-by-process where only the resulting structure of an appliance with cavities for the teeth and unerupted teeth are provided as detailed above). With respect to claim 9, wherein the cavity configured to accommodate the unerupted or erupting tooth is positioned to accommodate the unerupted or erupting tooth as the tooth erupts during the period of treatment (this is considered product-by-process where only the resulting structure of an appliance with cavities for the teeth and unerupted teeth are provided as detailed above; [106]). With respect to claim 10, wherein the dental appliance is based on a virtual dental appliance (this is considered product-by-process where only the resulting structure of an appliance with cavities for the teeth and unerupted teeth are provided as detailed above; “virtual model”, 741).
