Office Action

§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 . Continued Examination Under 37 CFR 1.114 A request for continued examination under 37 CFR 1.114, including the fee set forth in 37 CFR 1.17(e), was filed in this application after final rejection. Since this application is eligible for continued examination under 37 CFR 1.114, and the fee set forth in 37 CFR 1.17(e) has been timely paid, the finality of the previous Office action has been withdrawn pursuant to 37 CFR 1.114. Applicant's submission filed on 5/4/26 has been entered. Response to Arguments Applicant’s arguments, see pages 3,4 of remarks (pgs 6,7 of response) filed 5/4/26, with respect to the art rejection under 35 U.S.C. 103 have been fully considered and are persuasive. The rejection of claims 1,2 over Hall and Marrocco has been withdrawn. Claim Rejections - 35 USC § 112 The following is a quotation of the first paragraph of 35 U.S.C. 112(a): (a) IN GENERAL.—The specification shall contain a written description of the invention, and of the manner and process of making and using it, in such full, clear, concise, and exact terms as to enable any person skilled in the art to which it pertains, or with which it is most nearly connected, to make and use the same, and shall set forth the best mode contemplated by the inventor or joint inventor of carrying out the invention. The following is a quotation of the first paragraph of pre-AIA 35 U.S.C. 112: The specification shall contain a written description of the invention, and of the manner and process of making and using it, in such full, clear, concise, and exact terms as to enable any person skilled in the art to which it pertains, or with which it is most nearly connected, to make and use the same, and shall set forth the best mode contemplated by the inventor of carrying out his invention. Claims 1,2 are 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. The recitation of “capillary structure being made of polyester fibers or a synthetic material having mechanical properties equivalent to polyester fibers” is inclusive of a broad number of materials encompassed by synthetic or artificial materials having a mechanical property similar to polyester. While it is understood what polyester material is and its inherent mechanical properties are, the disclosure fails to detail what these other materials specifically are and what the exact mechanical properties intended to be encompassed by the recitation. The lack of any clear parameters on size, diameter, density, thickness, elasticity, etc. which could play a role in causing resistance in deformation leads to insufficient information to define boundaries for a synthetic material other than polyester. Because the Patent Office is not a testing facility it is impossible to know what the mechanical properties are intended to be for sufficient understanding of a synthetic material equivalent to polyester fibers and therefore the claims lack proper disclosure. Conclusion The prior art made of record and not relied upon is considered pertinent to applicant's disclosure. Holzer et al. disclose a stent apparatus that be a helical arrangement and have layers of polymer coated thereon using materials such as PTFE, polyurethane or polyester fibers.
