Office Action

§102
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 . Application Status This office action is responsive to the amendments filed on 05/26/2026. Claims 1-20 are pending and presented for examination. This action has been made FINAL. Claim Objections Claim 1 is objected to because of the following informalities: In view of the most recent claim amendments, it is unclear whether the Applicant intends for claim 1 to be an independent claim or dependent claim, since the claim has been amended to mention dependent claim 9. The examiner suggest deleting “of claim 9” from claim 1. Appropriate correction is required. Response to Arguments Applicant's arguments filed 05/26/2026 have been fully considered but they are not persuasive. The Applicant alleges the following: “Chumbley et al. fails to disclose, teach or suggest a fully parametric system in which (every) dimensional variable can be dynamically and continuously modified.” The examiner is not persuaded. Chumbley discloses the Applicant’s claim language of “provides continuous and dynamic adjustment within ranges across multiple independent adjustable parameters of the set of adjustable parameters” in Paragraphs 0062; 0102. Accordingly, the examiner maintains the rejection. The Applicant alleges the following: “Claim 9 is clarified, becoming an independent Claim reciting that the stretchable parametric model provides continuous and dynamic adjustment within ranges across multiple independent adjustable parameters of the set of adjustable parameters. It is respectfully submitted that Claim 9 is novel over Chumbley et al. Each of Claims 1-8 and 10-12 is patentable in view of its ultimate dependency from an allowable Claim 9 and the further recitation therein. Claim 13 recites the same subject matter related to the innovative use of the stretchable parametric model in a method for creating custom eyewear as recited in Claim 9. Claim 13 is novel over Chumbley et al. Each of Claims 14-20 is patentable in view of its ultimate dependency from an allowable Claim 13 and the further recitation therein.” The examiner is not persuaded. The Applicant is rehashing arguments already addressed above. Nonetheless, the examiner asserts Chumbley discloses the Applicant’s claim language of “provides continuous and dynamic adjustment within ranges across multiple independent adjustable parameters of the set of adjustable parameters” in Paragraphs 0062; 0102. More specifically, Chumbley’s teachings of “the eyewear customization system 220 or some other system) can generate a 3D eyewear model defining a particular style of eyewear, such as a specific eyeglass frame, goggles, or the like. In addition, the eyewear model defining a particular style of eyewear may include or otherwise be associated with data indicating which portions of the eyewear may be customized, the manner or degree to which the eyewear may be customized, etc. For example, an eyewear designer or manufacturer may offer several different styles of sunglasses (e.g., dozens or hundreds of different styles). A separate eyewear model may be generated or obtained for each of the styles or for some subset thereof. The eyewear model for a particular style may include measurements, relationships, and other parameters defining the style (or individual components thereof). In addition, the eyewear model may include, or be modified to include, information regarding the customizations that may be made to the eyewear while still maintaining the features and design elements of the particular style. In some embodiments, the eyewear model may include ranges within which specific components may be created or modified, or minimum/maximum sizes or other measurements for various components. For example, the eyewear model may specify a value between 0.5 mm and 1.50 mm as the maximum adjustment to the distance between the lenses or to the distance of each lens from the center point between the lenses; in some cases, this maximum may be specified as 1 mm.” in paragraph 0062 discloses the Applicant’s claim language. MPEP § 2106 states Office personnel are to give claims their broadest reasonable interpretation in light of the supporting disclosure. In re Morris, 127 F.3d 1048, 1054-55, 44 USPQ2d 1023, 1027-28 (Fed Cir. 1997). Accordingly, the examiner maintains the rejection. 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.
