Office Action

§102
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 . Response to Amendment This office action is responsive to the preliminary amendment filed on 5/10/2022. As directed by the amendment: no claims have been amended, claims 1-13 have been cancelled, and claims 14-33 have been added. Thus, claims 14-33 are presently pending in this application. Claim Objections Claim 14 recites the limitation “the proximal end of the biased plunger rod” in lines 12 and 14. There is insufficient antecedent basis for this limitation in the claim. Claim 17 recites the limitation "the first, the second and the third retaining member” in lines 3-4. There is insufficient antecedent basis for this limitation in the claim. Claim 19 recites the limitation “the first retaining member” in line 4. There is insufficient antecedent basis for this limitation in the claim. Claim 20 recites the limitation “the second retaining member” in line 4. There is insufficient antecedent basis for this limitation in the claim. Claim 21 recites the limitation “the third retaining member” in line 3. There is insufficient antecedent basis for this limitation in the claim. Claim 23 recites the limitation "the second retaining member” in line 2. There is insufficient antecedent basis for this limitation in the claim. Claim 24 recites the limitation “the first and the second retaining member” in line 2 and in line 4. There is insufficient antecedent basis for this limitation in the claim. Claim 29 is objected to because of the following informalities: “wherein the” is repeated in the sentence twice back to back. Appropriate correction is required. 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)(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.
