Office Action

§102 §103 §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. This is the first office action in response to the above identified patent application filed on 12/29/2023 . Claims 1-21 are currently pending and being examined. Claim Interpretation The following is a quotation of 35 U.S.C. 112(f): (f) Element in Claim for a Combination. – An element in a claim for a combination may be expressed as a means or step for performing a specified function without the recital of structure, material, or acts in support thereof, and such claim shall be construed to cover the corresponding structure, material, or acts described in the specification and equivalents thereof. The following is a quotation of pre-AIA 35 U.S.C. 112, sixth paragraph: An element in a claim for a combination may be expressed as a means or step for performing a specified function without the recital of structure, material, or acts in support thereof, and such claim shall be construed to cover the corresponding structure, material, or acts described in the specification and equivalents thereof. This application includes one or more claim limitations that do not use the word “means,” but are nonetheless being interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, because the claim limitation(s) uses a generic placeholder that is coupled with functional language without reciting sufficient structure to perform the recited function and the generic placeholder is not preceded by a structural modifier. Such claim limitation(s) is/are: engagement structure in claim 1 FILLIN "Indicate the claim(s) in which each respective limitation appears." \d "[ 2 ]" . According to the specification, the engagement structure can include either an O-ring or fins ( par. 5, 7, 12, 38 ). Because this/these claim limitation(s) is/are being interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, it/they is/are being interpreted to cover the corresponding structure described in the specification as performing the claimed function, and equivalents thereof. If applicant does not intend to have this/these limitation(s) interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, applicant may: (1) amend the claim limitation(s) to avoid it/them being interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph (e.g., by reciting sufficient structure to perform the claimed function); or (2) present a sufficient showing that the claim limitation(s) recite(s) sufficient structure to perform the claimed function so as to avoid it/them being interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph. 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 appl icant regards as his invention. Claim s 1-21 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 s " an open configuration " and “ a closed configuration ” in line 5 . It is unclear from the claims what is meant by open and closed configuration s for the claim does not provide a definition at all. Also, the specification does not provide a clear definition of what is meant by these configuration other than locked and unlocked, which can also be open to interpretation for it is unclear what components are locked or unlocked. Thus, the above recitation s are ambiguous and opened to a variety of interpretation s . Although the claims are interpreted in light of the specification, limitations from the specification are not read into the claims. See In re Van Geuns , 988 F.2d 1181, 26 USPQ2d 1057 (Fed. Cir. 1993). Appropriate correction is required. Claim 1 recites the limitation " an open configuration " in line s 7-8 . It is unclear if this recitation should refer back to the previously recited “ an open configuration ” in line 5 or if this is a new recitation separate and different but with a same name Appropriate correction is required. Claim 1 5 recites the limitation s " the closed position " and “ the open position ” in line 3 . There is insufficient antecedent basis for this limitation in the claim. Appropriate correction is required. Claims 2-14 and 16-21 depend from Claim 1 and are rejected accordingly. 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.

Regarding dependent Claim 21 , Vendely discloses wherein the tab 292 further includes a handle (in figure 15, the portion of the tab 292 protruding perpendicular to the longitudinal axis L of the stem 248; refer also to figure 6 to see the longitudinal axis) extending from a distal end of the shaft (the physical structure of the cylindrical channel formed when the tab connect the surface 294 on the cathlock , refer particularly to figures 15-18) , perpendicular to the longitudinal axis L , and configured to facilitate grasping the tab (a protrusion is easier to grasp than a component having no protrusion) . Claim s 4, 5, 13 and 14 are rejected under 35 U.S.C. 102(a)(1) and/or 102(a)(2) as being anticipated by Thomas et al. ( WO 2022/036095) . The applied reference has a common assignee and or inventor with the instant application. Based upon the earlier effectively filed date of the reference, it constitutes prior art under 35 U.S.C. 102(a)(2). This rejection under 35 U.S.C. 102(a)(2) might be overcome by: (1) a showing under 37 CFR 1.130(a) that the subject matter disclosed in the reference was obtained directly or indirectly from the inventor or a joint inventor of this application and is thus not prior art in accordance with 35 U.S.C. 102(b)(2)(A); (2) a showing under 37 CFR 1.130(b) of a prior public disclosure under 35 U.S.C. 102(b)(2)(B) if the same invention is not being claimed; or (3) a statement pursuant to 35 U.S.C. 102(b)(2)(C) establishing that, not later than the effective filing date of the claimed invention, the subject matter disclosed in the reference and the claimed invention were either owned by the same person or subject to an obligation of assignment to the same person or subject to a joint research agreement. In regards to Independent Claim 1 , and with particular reference to Figures 1, 2a, 2b, Thomas discloses a locking mechanism for coupling a catheter 128 to a port 130 , comprising: a stem 132/116/ 118 extending along a longitudinal axis (longitudinal axis shown in figure 1 ) , a distal end of the stem (in figures 2a and 2b shown but not labeled, the distal end of stem) configured to engage a lumen of the catheter ( 128 ) , a proximal end of the stem coupled to the port (as shown in figure 2a ) ; a cathlock having an engagement structure ( fins 124 and O-ring 122 ) configured to engage the catheter 128 and transitionable between an open configuration (when catheter 128 is connected to the stem, the cathete r is further pushing inwardly the angled fins 124 towards the port body 130 ) and a closed configuration (when the catheter 128 is not further pushing inwardly the angled fin s 124 ) and biased (the fins are somewhat bias/angled inwardly towards the port body even when the catheter 128 is not connected to the stem and the fin s are not engaging/touching the catheter 128 ) to the closed configuration; and a tab 200 configured to engage the cathlock ( as shown in figure 2B ) to maintain the engagement structure ( fin s 124 and/or O-ring 122 ) in the open configuration ( as explained above ) , the tab ( 200 ) selectively removable ( par. 56, 57, the component can be removed/separated from ) from the cathlock to transition the engagement structure from the open configuration ( as explained above ) to the closed configuration ( as explained above ). Regarding dependent Claim 4 , Thomas discloses wherein the engagement structure includes one or more fins 224 extending radially inward and elastically deformable to a radial outward open configuration , refer particularly to figures 2 A,B , Regarding dependent Claim 5 , Thomas discloses wherein the one or more fins 224 extend at an angle (at the angle show s in figures 2 a,b ) relative to the longitudinal axis (axis shown in figure 1) and either extend perpendicular to the longitudinal axis, or extend proximally toward the port ( as shown in figures 2a,b ) . Regarding dependent Claim 13 , Thomas discloses wherein the engagement structure includes an O-ring 122 extending annularly about the axis of the stem, and elastically deformable to a radial outward open configuration. Regarding dependent Claim 1 4 , Thomas discloses wherein the O-ring 122 in the closed configuration defines an inner diameter that is less than an outer diameter of the catheter , refer to figures 2 a,b . Claim Rejections - 35 USC § 103 The following is a quotation of 35 U.S.C. 103 which forms the basis for all obviousness rejections set forth in this Office action: A patent for a claimed invention may not be obtained, notwithstanding that the claimed invention is not identically disclosed as set forth in section 102, if the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to which the claimed invention pertains. Patentability shall not be negated by the manner in which the invention was made. The factual inquiries for establishing a background for determining obviousness under 35 U.S.C. 103 are summarized as follows: 1. Determining the scope and contents of the prior art. 2. Ascertaining the differences between the prior art and the claims at issue. 3. Resolving the level of ordinary skill in the pertinent art. 4. Considering objective evidence present in the application indicating obviousness or nonobviousness . Claim s 2-3 are rejected under 35 U.S.C. 103 as being unpatentable over Vendely . Regarding dependent Claim 2 , Vendely teaches the invention as claimed and as disclosed above for claim 1 including the cathlock (280 a,b and 258a,b in figures 15-18; or 180a,b in figures 12-14) and the port (226 in figures 15-18; or 126 in figures 12-14) except the cathlock ( of figures 12-1 8 ) is integrally formed with the port ( of figures 12-18 ) . However, Vendely teaches the cathlock ( 58 in figure 5; col. 2 lines 41-43) is integrally formed with the port 32. It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to have made the cathlock (in figures 12-18) integrally formed with the port (in figures 12-18), as taught by Vendely (in figure 5; col. 2 lines 41-43), since it has been held that use of a one piece construction instead of the structure disclosed in the prior art would be merely a matter of obvious engineering choice ( In re Larson , 340 F.2d 965, 968, 144 USPQ 347, 349 (CCPA 1965)). MPEP 2144.04 V B. Regarding dependent Claim 3 , Vendely as modified above in claim 2 teaches the invention as claimed and as disclosed above and Vendely as modified further teaches wherein the cathlock (280a,b and 258a,b in figures 15-18; or 180a,b in figures 12-14) includes a cowl (the physical structure of the cowl) extending from a body of the port (226, 126) and defining a recess (recess receiving the stem 248 or 148 is shown but not labeled, refer to figures 13-18), the recess extending longitudinally from a distal tip of the cowl and including the stem (248, 148) disposed therein. Allowable Subject Matter Claim s 18-20 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. Pertinent Prior Art The prior art made of record and not relied upon is considered pertinent to applicant's disclosure.
