Office Action

§103 §112
DETAILED ACTION In response to the Office Action mailed 01/26/2026, the response was received 03/30/2026: Claims 1, 2, 9, 10, 14, 18 and 20 have been amended. Claim 21 is new. Claims 1-14 and 16-21 are pending. Claim 20 is withdrawn. Drawings The drawings are objected to under 37 CFR 1.83(a). The drawings must show every feature of the invention specified in the claims. Therefore, the shield plate comprising a window, a first sub-shield plate, and a second sub-shield plate, and having a rotating center about which the shield plate rotates, the window and the rotating center being located at opposite end portions of the shield plate, and a driving mechanism configured to drive the first sub-shield plate and the second sub-shield plate to approach each other or move away from each other to adjust the shielding area must be shown or the feature(s) canceled from the claim(s). Therefore, “the shield plate being provided with a window and having a rotating center about which the shield plate rotates, the window and the rotating center being located at opposite end portions of the shield plate; and a driving mechanism configured to drive the shield plate to adjust a shape of a radiating surface of outputting rays penetrating the collimator” according to claim 1 in combination with “wherein the shield plate comprises a first sub-shield plate and a second sub-shield plate, and the driving mechanism is configured to drive the first sub-shield plate and the second sub-shield plate to approach each other or move away from each other to adjust the shielding area” according to claim 6 must be shown or the feature(s) canceled from the claim(s). No new matter should be entered. 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. 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. Claim 6 is rejected under 35 U.S.C. 112(a) or 35 U.S.C. 112 (pre-AIA ), first paragraph, as failing to comply with the written description requirement. The claim(s) contains subject matter which was not described in the specification in such a way as to reasonably convey to one skilled in the relevant art that the inventor or a joint inventor, or for applications subject to pre-AIA 35 U.S.C. 112, the inventor(s), at the time the application was filed, had possession of the claimed invention. Neither the specification nor the drawings show or describe how the driving mechanism is both rotating the shield plate and separating the sub-shield plates. Further, neither the specification nor the drawings show or describe a rotating shield comprised of two parts (first sub-shield and second sub-shield) as described in the newly amended claims. Claim 6 is rejected under 35 U.S.C. 112(a) or 35 U.S.C. 112 (pre-AIA ), first paragraph, as failing to comply with the enablement requirement. The claim(s) contains subject matter which was not described in the specification in such a way as to enable one skilled in the art to which it pertains, or with which it is most nearly connected, to make and/or use the invention. Neither the specification nor the drawings show or describe how the driving mechanism is both rotating the shield plate and separating the sub-shield plates. Further, neither the specification nor the drawings show or describe a rotating shield comprised of two parts (first sub-shield and second sub-shield) as described in the newly amended claims. Election/Restrictions Newly amended claims 1-21 directed to an invention that is independent or distinct from the invention originally claimed for the following reasons: Originally presented claims are directed to a mutually exclusive species shown in figures 1 and 4-6. Newly amended claims are drawn to a mutually exclusive species shown in figure 10. Since applicant has received an action on the merits for the originally presented invention, this invention has been constructively elected by original presentation for prosecution on the merits. Accordingly, claims 1-21 withdrawn from consideration as being directed to a non-elected invention. See 37 CFR 1.142(b) and MPEP § 821.03. To preserve a right to petition, the reply to this action must distinctly and specifically point out supposed errors in the restriction requirement. Otherwise, the election shall be treated as a final election without traverse. Traversal must be timely. Failure to timely traverse the requirement will result in the loss of right to petition under 37 CFR 1.144. If claims are subsequently added, applicant must indicate which of the subsequently added claims are readable upon the elected invention. Should applicant traverse on the ground that the inventions are not patentably distinct, applicant should submit evidence or identify such evidence now of record showing the inventions to be obvious variants or clearly admit on the record that this is the case. In either instance, if the examiner finds one of the inventions unpatentable over the prior art, the evidence or admission may be used in a rejection under 35 U.S.C. 103 or pre-AIA 35 U.S.C. 103(a) of the other invention. Claims 1-21 are withdrawn from further consideration pursuant to 37 CFR 1.142(b) as being drawn to a nonelected species, there being no allowable generic or linking claim. Election was made by original presentation in the disclosure filed on 10/12/2023. 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 nonprovisional extension fee (37 CFR 1.17(a)) 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.
