Office Action

§112
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 . Response to Restriction - Election without Traverse Due to Incomplete Reply Applicant’s election of I in the reply filed September 4, 2025 is acknowledged. Because the applicant did not distinctly and specifically point out the supposed errors in the restriction requirement, the election has been treated as an election without traverse (MPEP § 818.01(a)). Claim to group II withdrawn from further consideration by the applicant as being drawn to a non-elected invention. Claim Rejections - 35 USC § 112(a) & (b) The claim is rejected under 35 USC § 112(a) and (b) as the claimed invention is not described in such full, clear, concise, and exact terms as to enable any person skilled in the art to make and use the same, and fails to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor regards as the invention. The visual disclosure is inadequate such that the appearance and shape or configuration of the design for which protection is sought cannot be determined or understood (MPEP § 1504.04), specifically: The depths of features A, shaded below, are unclear. The features are shown only in Fig. 1.1. The features appear to be located somewhere within the body of the design. However, the features could exist anywhere within the range indicated on annotated Fig. 1.3, below. Therefore, the exact locations of the features are open to conjecture due to lack of additional disclosure. PNG media_image1.png 365 472 media_image1.png Greyscale Fig. 1.1 PNG media_image2.png 332 654 media_image2.png Greyscale Fig. 1.3 The depth of feature B is unclear. The feature is shown only in Fig. 1.2. The feature appears to be located somewhere within the body of the design. However, the feature could exist anywhere within the range indicated on annotated Fig. 1.3, below. Therefore, the exact location of the feature is open to conjecture due to lack of additional disclosure. PNG media_image3.png 298 345 media_image3.png Greyscale Fig. 1.2 PNG media_image4.png 452 646 media_image4.png Greyscale Fig. 1.3 The depths of features C, shaded below, are unclear. The features are shown only in Fig. 1.6. The features appear to be located somewhere within the body of the design. However, the features could exist anywhere within the range indicated on annotated Fig. 1.3, below. Therefore, the exact locations of the features are open to conjecture due to lack of additional disclosure. PNG media_image5.png 693 866 media_image5.png Greyscale Fig. 1.6 PNG media_image6.png 252 697 media_image6.png Greyscale Fig. 1.3 The depths of features D, shaded below, are unclear. The features are shown only in Fig. 2.1. The features appear to be located somewhere within the body of the design. However, the features could exist anywhere within the range indicated on annotated Fig. 2.3, below. Therefore, the exact locations of the features are open to conjecture due to lack of additional disclosure. PNG media_image7.png 193 273 media_image7.png Greyscale Fig. 2.1 PNG media_image8.png 267 535 media_image8.png Greyscale Fig. 2.3 The depth of feature E is unclear. The feature is shown only in Fig. 2.2. The feature appears to be located somewhere within the body of the design. However, the feature could exist anywhere within the range indicated on annotated Fig. 2.3, below. Therefore, the exact location of the feature is open to conjecture due to lack of additional disclosure. PNG media_image9.png 382 299 media_image9.png Greyscale Fig. 2.2 PNG media_image10.png 413 555 media_image10.png Greyscale Fig. 2.3 The depths of features F are unclear. The features are shown only in Fig. 2.6. The features appear to be located somewhere within the body of the design. However, the features could exist anywhere within the range indicated on annotated Fig. 2.3, below. Therefore, the exact locations of the features are open to conjecture due to lack of additional disclosure. PNG media_image11.png 721 882 media_image11.png Greyscale Fig. 2.6 PNG media_image12.png 290 700 media_image12.png Greyscale Fig. 2.3 Because of the inadequate disclosure, the claimed design is in fact subject to multiple interpretations, and one of ordinary skill in the art would not be able to make and use the design without the use of conjecture. This renders the claim indefinite and non-enabled. To overcome this rejection, it is suggested that the applicant submit new drawings of the claimed design that show the design clearly and consistently. However, if certain non-enabled portions of the design cannot be fully enabled without the introduction of new matter, the applicant may remove from the claim the areas or portions of the design that are considered indefinite and non-enabling by converting them to broken line and amending the specification to indicate those portions form no part of the claimed design. Corrected drawing sheets in compliance with 37 CFR 1.121(d) 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. The figure or figure number of an amended drawing should not be labeled as “amended.” If a drawing figure is to be canceled, the appropriate figure must be removed from the replacement sheet, and where necessary, the remaining figures must be renumbered and appropriate changes made to the brief description of the several views of the drawings for consistency. Additional replacement sheets may be necessary to show the renumbering of the remaining figures. 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. When preparing new or replacement drawings, be careful to avoid introducing new matter. New matter is prohibited by 35 U.S.C. 132 and 37 CFR 1.121(f). Conclusion The claim stands refused for the reasons set forth above.
