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 . Applicant’s response of 03/12/2026, including an amended specification/claim and replacement drawings, has been reviewed. The objection to the specification/claim and objection to the drawings have been overcome. However, there is a new objection to the drawings and the rejection under 35 USC § 112(a) and (b) has not been fully overcome and is made final as set forth below. Objection to the Drawings The drawings are objected to due to the following inconsistencies: 1) Figures 2.4, 3.4, 3.5, 4.3, 4.4, 4.5, and 4.6 are missing the horizontal edges of the ring at the base of the cylindrical feature. Please see the annotated drawings below. PNG media_image1.png 735 1839 media_image1.png Greyscale 2) Figure 3.4 shows the indicated cap in broken lines which is inconsistent with the other views. Please see the annotated drawings below. PNG media_image2.png 726 2015 media_image2.png Greyscale To overcome this objection, applicant may amend the drawings by showing the indicated above features consistently across all applicable views. Rejection 35 USC § 112(a) and (b) The claim is rejected under 35 U.S.C. 112(a) and (b) or pre-AIA 35 U.S.C. 112, first and second paragraphs, 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 (or, for applications subject to pre-AIA 35 U.S.C. 112, the applicant) regards as the invention. Some of the features that were indicated as nonenabled and indefinite in the previous office action dated 12/16/2025 were not converted to broken lines to form no part of the claimed design. Please see the annotated drawings below. The exact shape and dimensionality of the indicated interior features shown in gray, cannot be fully understood due to the insufficient disclosure.

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. If all the figures on a drawing sheet are canceled, a replacement sheet is not required. A marked-up copy of the drawing sheet (labeled as “Annotated Sheet”) including an annotation showing that all the figures on that drawing sheet have been canceled must be presented in the amendment or remarks section that explains the change to the drawings. 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 changes are not accepted by the examiner, the applicant will be notified and informed of any required corrective action in the next Office action. 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/Contact Information The drawings are objected to for the reasons set forth above. The claim is rejected under 35 USC § 112(a) and (b) for the reasons set forth above. 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 extension fee 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 date of this final action.
