Office Action

§112
DETAILED ACTION 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 Arguments Applicant’s arguments filed on 3/18/26 have been considered but are moot because the arguments do not apply to any of the references being used in the current rejection. The amendment necessitates the new ground(s) of rejection presented due to the added language in the independent claim(s). Status of the Application Claim(s) 1-2, 4-11, 13-20 is/are pending. Claim(s) 19-20 is/are withdrawn. Claim(s) 1-2, 4-11, 13-18 is/are rejected. Claim Rejections – 35 U.S.C. § 112(b) The following is a quotation of 35 U.S.C. 112(b): PNG media_image1.png 120 1248 media_image1.png Greyscale The following is a quotation of 35 U.S.C. 112 (pre-AIA ), second paragraph: PNG media_image2.png 89 869 media_image2.png Greyscale Claim(s) 1-2, 4-11, 13-18 is/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 pre-AIA the applicant regards as the invention. Claims 1 and 10 recite the limitation “wherein the plate is movable to position the aperture” is vague and indefinite because the claim does not provide a discernable boundary on what performs the function. The recited function does not follow from the structure recited in the claim, so it is unclear whether the function requires some other structure or is simply a result of operating the implantation system in a certain manner. Thus, one of ordinary skill in the art would not be able to draw a clear boundary between what is and is not covered by the claim. See MPEP 2173.05(g) for more information. Claims 2, 4-9, 11, 13-18 are rejected due to their dependency from claims 1, 10. Conclusion Applicant's amendment necessitated the new ground(s) of rejection presented in this Office action. Accordingly, 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 mailing date of this final action.
