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 Arguments Applicant's arguments filed 9/09/2025 have been fully considered. Regarding the rejection under 35 U.S.C. 102(a)(1) as being anticipated by Porges (Ismael Bernard) EP0935974, applicant states: Ismael does not disclose all of the elements of claim 1. Specifically, Ismael does not disclose, "wherein at least one of said elementary cylindrical tubes comprises a transverse support positioned inside a cylinder of the at least one elementary cylindrical tube, wherein the transverse support has an orifice configured to guide said cylindrical element through the orifice, wherein the tubular telescopic assembly is configured to retract as the cylindrical element is pushed from a proximal end towards a distal end of the tubular telescopic assembly" as recited in claim 1. The examiner disagrees and his position is in the grounds of rejection below. The claim amendments overcame the previous rejection under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), second paragraph. 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. Claims 1-2 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Bernard (EP0935974). Bernard teaches an anti-buckling device for guiding a cylindrical element into an opening of a conduit (this is interpreted as functional language which the of Bernard is fully capable of), the device comprising: PNG media_image1.png 126 538 media_image1.png Greyscale at least two elementary cylindrical tubes (for example t3, t4) that are nested and guided mutually in one another to form a tubular telescopic assembly having an axis XX' (longitudinal) and of a given length L, wherein at least one of said elementary tubes (for example t3) comprises a transverse support (narrowed portion at 4.3) positioned inside a cylinder of the at least one elementary cylindrical tube, wherein the transverse support has an orifice (inherent) configured to guide said cylindrical element (not positively claimed, see for example 3.1) through the orifice, wherein the tubular telescopic assembly is configured to retract as the cylindrical element is pushed from the proximal end (generally 5.1) towards a distal end (generally 2.1) of this tubular telescopic assembly. Note, the proximal end and distal end can be reversed and the device will fulfill the language. PNG media_image2.png 170 764 media_image2.png Greyscale Claim 2, referring to figure 4 above, the transverse support (stated above) is positioned at the distal end (distal end is half of the tube) of the elementary cylindrical tube end by which it slides into an adjacent elementary cylindrical tube of larger diameter. This claim is interpreted as a small diameter tube t3 slides into a larger diameter tube t4. Allowable Subject Matter Claims 4-13 are objected to as being dependent upon a rejected base claim, but would be allowable if rewritten in independent form including all of the limitations of the base claim and any intervening claims. The following is a statement of reasons for the indication of allowable subject matter: Bernard, used in the rejection above, and Douk (2005/00045553) are considered the closes prior art of record. PNG media_image3.png 232 772 media_image3.png Greyscale PNG media_image4.png 257 741 media_image4.png Greyscale Both Bernard and Douk fail to teach all limitations of claim 1 in combination with the limitations of claims 4-13. Applicant is invited to discuss any prior art if desired.
