Office Action

§102 §112
DETAILED ACTION 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 . 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(s) 1-15 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 applications subject to pre-AIA 35 U.S.C. 112, the applicant), regards as the invention. Claim 1 recites the limitation "the thickness of the posterior haptic wall" in Lines 9-10. There is insufficient antecedent basis for this limitation in the claim. Claim(s) 2-15, which depend from claim 1, inherit all the problems associated with claim 1. Claim 7 recites the limitation "the thickness of the radially-outer haptic wall" in line 2. There is insufficient antecedent basis for this limitation in the claim. Claim 10 recites the limitation "the thickness of the radially-inner haptic wall " in lines 1-2. There is insufficient antecedent basis for this limitation in the claim. Claim 10 recites the limitation "the thickness of the radially-outer haptic wall " in line 2. There is insufficient antecedent basis for this limitation in the claim. Claim Rejections - 35 USC § 102 In the event the determination of the status of the application as subject to AIA 35 U.S.C. 102 and 103 (or as subject to pre-AIA 35 U.S.C. 102 and 103) is incorrect, any correction of the statutory basis (i.e., changing from AIA to pre-AIA ) for the rejection will not be considered a new ground of rejection if the prior art relied upon, and the rationale supporting the rejection, would be the same under either status. The following is a quotation of the appropriate paragraphs of 35 U.S.C. 102 that form the basis for the rejections under this section made in this Office action: A person shall be entitled to a patent unless – (a)(1) the claimed invention was patented, described in a printed publication, or in public use, on sale, or otherwise available to the public before the effective filing date of the claimed invention. (a)(2) the claimed invention was described in a patent issued under section 151, or in an application for patent published or deemed published under section 122(b), in which the patent or application, as the case may be, names another inventor and was effectively filed before the effective filing date of the claimed invention. Claim(s) 1, 4, 6-8, 10, 30 is/are rejected under 35 U.S.C. 102(a)(1) and 35 U.S.C. 102(a)(2) as being anticipated by Park (US 2010/0063588 A1).

Allowable Subject Matter Claim(s) 12-15 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. Claim(s) 16-18 is/are allowable over the prior art of record. The following is a statement of reasons for the indication of allowable subject matter: Examiner can find no references alone nor in combination which render obvious: With respect to claim 12 and 16: An IOL comprising: an optic portion comprising an optic fluid chamber; a haptic having a proximal end coupled to the optic portion and a distal free end, the haptic comprising a haptic fluid lumen extending through at least part of the haptic and in fluid communication with the optic fluid chamber; and one or more support columns disposed within the haptic fluid lumen, and wherein the one or more support columns are configured to maintain a shape of the haptic fluid lumen in response to forces applied to the haptic as a result of capsular contraction. (Note: Esch et al. discloses an IOL with an optic portion containing a fluid optic chamber and a haptic coupled thereto with a haptic fluid lumen. Additionally, Esch et al. discloses an internal structure within the haptic fluid lumen. However, Esch et al. does not disclose the aforementioned internal structure as configured to/ capable of maintaining the shape of the haptic fluid lumen. Instead, Esch et al. discloses the haptic fluid lumen as configured to/ intending to change shape in response to forces applied by the capsular bag (the opposite of the claimed subject matter).)
