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 . Priority Receipt is acknowledged of certified copies of papers required by 37 CFR 1.55. Information Disclosure Statement The information disclosure statement (IDS) submitted on 12/8/2025 has been considered by the examiner. Drawings The drawings are objected to as failing to comply with 37 CFR 1.84(p)(5) because they do not include the following reference sign(s) mentioned in the description: 254. 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. 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. Claims 1-8 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 applications subject to pre-AIA 35 U.S.C. 112, the applicant), regards as the invention. Claim 1 recites “is derived from a basic shape of a quarter circle” in lines 20-21, which is unclear and renders the claims indefinite. Specifically, the phrase “derived from” and “a basic shape” make it unclear if the shape of the deflection section is that of a quarter circle, or some other shape. As such, the shape of the deflection section required by the claims cannot be determined. Claim 1 recites “the ball deflection” in line 22 of the claim, which is unclear and renders the claims indefinite. Specifically, “two ball deflections” are previously claimed, and the ball deflection referenced by the recitation of “the ball deflection” cannot be determined. Claim 1 recites “an ideal of the basic shape of the quarter circle” in lines 23-24, which is unclear and renders the claims indefinite. Specifically, it is unclear what distance and what end plane are being defined, as the phrase “an ideal of the…” further confuses the shape of the deflection section, and the offset being claimed cannot be determined. Claim 1 recites “d1 ≈ d2” which is unclear and renders the claims indefinite. Specifically, the relationship between the claimed distances cannot be determined, as it is unclear what is required by “≈”. Claim 8 recites “wherein “d1 ≥ d2” which is unclear and renders the claims indefinite. Specifically, Claim 1 defines the relationship as “d1 ≈ d2”, and it is unclear how both conditions can exist. Allowable Subject Matter Claim 1 would be allowable if rewritten or amended to overcome the rejection(s) under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), 2nd paragraph, set forth in this Office action. Claims 2-7 would be allowable if rewritten to overcome the rejection(s) under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), 2nd paragraph, set forth in this Office action and to include all of the limitations of the base claim and any intervening claims.
