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and the fee set forth in 37 CFR 1.17(e) has been timely paid, the finality of the previous Office action has been withdrawn pursuant to 37 CFR 1.114.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 06/18/2026 has been entered.
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.
The claims in this application are given their broadest reasonable interpretation using the plain meaning of the claim language in light of the specification as it would be understood by one of ordinary skill in the art. The broadest reasonable interpretation of a claim element (also commonly referred to as a claim limitation) is limited by the description in the specification when 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, is invoked.
As explained in MPEP § 2181, subsection I, claim limitations that meet the following three-prong test will be interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph:
(A) the claim limitation uses the term “means” or “step” or a term used as a substitute for “means” that is a generic placeholder (also called a nonce term or a non-structural term having no specific structural meaning) for performing the claimed function;
(B) the term “means” or “step” or the generic placeholder is modified by functional language, typically, but not always linked by the transition word “for” (e.g., “means for”) or another linking word or phrase, such as “configured to” or “so that”; and
(C) the term “means” or “step” or the generic placeholder is not modified by sufficient structure, material, or acts for performing the claimed function.
Use of the word “means” (or “step”) in a claim with functional language creates a rebuttable presumption that the claim limitation is to be treated in accordance with 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph. The presumption that the claim limitation is interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, is rebutted when the claim limitation recites sufficient structure, material, or acts to entirely perform the recited function.
Absence of the word “means” (or “step”) in a claim creates a rebuttable presumption that the claim limitation is not to be treated in accordance with 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph. The presumption that the claim limitation is not interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, is rebutted when the claim limitation recites function without reciting sufficient structure, material or acts to entirely perform the recited function.
Claim limitations in this application that use the word “means” (or “step”) are being interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, except as otherwise indicated in an Office action. Conversely, claim limitations in this application that do not use the word “means” (or “step”) are not being interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, except as otherwise indicated in an Office action.
Currently, none of the claim limitations are interpreted under 35 U.S.C. 112(f).
Claim Rejections - 35 USC § 103
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 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 text of those sections of Title 35, U.S. Code not included in this action can be found in a prior Office action.
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.
This application currently names joint inventors. In considering patentability of the claims the examiner presumes that the subject matter of the various claims was commonly owned as of the effective filing date of the claimed invention(s) absent any evidence to the contrary. Applicant is advised of the obligation under 37 CFR 1.56 to point out the inventor and effective filing dates of each claim that was not commonly owned as of the effective filing date of the later invention in order for the examiner to consider the applicability of 35 U.S.C. 102(b)(2)(C) for any potential 35 U.S.C. 102(a)(2) prior art against the later invention.
Claim(s) 1, 2, and 8-15 is/are rejected under 35 U.S.C. 103 as being unpatentable over Zhang et al. (US Pub. No.: 2010/0145286) in view of Darois et al. (US Pub. No.: 2005/0085924) and Boey et al. (US Pub. No.: 2012/0010636).
Regarding claims 1, 2, and 8-15, Zhang discloses (claim 1) a biodegradable synthetic surgical mesh (hernia repair mesh, Paras. [0066]-[0072]. poly(orthoesters) and polyolefins are biodegradable. Paras. [0010] and [0091] also describe that the non-fouling coating can be biodegradable) comprising a polymeric material (Paras. [0066]-[0075] and [0100]-[0109], a polymeric medical device which can be hernia repair mesh formed of poly(orthoesters), polyolefins and/or polypropylene and coated with zwitterionic groups) and an antimicrobial (Paras. [0061], [0137], [0138], and [0161]), wherein the surface of one side of said mesh is functionalized with a zwitterionic functional group (Paras. [0015], [0021], [0066]-[0075], and [0100]-[0109], non-fouling material, such as zwitterionic functional group) comprising at least one of a polybetaine, sulfobetaine methacrylate (SBMA), carboxybetaine methacrylate (CBMA), or a polyampholyte (Paras. [0015] and [0021]); (claim 2) wherein the polymer material comprises polypropylene (Para. [0070]); (claim 8) wherein said mesh is non-woven (Paras. [0066] and [0076] and claim 2, hernia repair mesh with non-woven fibers); (claim 9) a kit for use in performing a surgical procedure, comprising the synthetic surgical mesh of claim 1 (Paras. [0066]-[0076] and [0100]-[0109], hernia repair mesh, the polymeric medical device can be hernia repair mesh formed of poly(orthoesters), polyolefins and/or polypropylene and coated with zwitterionic groups); (claim 10) a method of performing a surgical procedure comprising implantation of the synthetic surgical mesh of claim 1 (Para. [0072], hernia repair); and (claim 11) wherein said surgical procedure comprises a hernia repair procedure (Para. [0072], hernia repair); (claim 12) wherein said zwitterionic functional group comprises a polybetaine (Para. [0021]); (claim 13) wherein said zwitterionic functional group comprises sulfobetaine methacrylate (SBMA) (Para. [0015]); (claim 14) wherein said zwitterionic functional group comprises carboxybetaine methacrylate (CBMA) (Para. [0015]); (claim 15) wherein said zwitterionic functional group comprises a polyampholyte (Para. [0021]). However, Zhang does not disclose that the antimicrobial comprises biguanides, and the surface of another side of said mesh consists of an anti-adhesive polymer.
Darois teaches, in the same field of endeavor (hernia mesh), a mesh (10, Fig. 1 and Paras. [0016] and [0042]) comprising an antimicrobial (Para. [0016]); wherein the antimicrobial comprises biguanides (Para. [0026]).
Before the effective filing date of the claimed invention, it would have been obvious to one of ordinary skill in the art to modify the antimicrobial of Zhang to be biguanides as taught by Darois, since it has been held to be within the general skill of a worker in the art to select a known material on the basis of its suitability for the intended use. See MPEP 2144.07.
Boey teaches, in the same field of endeavor (hernia mesh), another side (bottom side) of a surgical mesh (combination of 10 and 20, Fig. 4 and Paras. [0047] and [0033]) consisting of an anti-adhesive polymer (anti-adhesive polymer layer 30, Fig. 4 and Para. [0050]-[0051]); wherein the anti-adhesive polymer comprises pectin (Para. [0050]).
Before the effective filing date of the claimed invention, it would have been obvious to one of ordinary skill in the art to modify the other side / another side of the surgical mesh of Zhang to consist of an anti-adhesive polymer serving as barrier, wherein the anti-adhesive polymer comprises pectin as taught by Boey in order to obtain the advantage of preventing any adhesion of prosthesis and organs or tissues to avoid undesired fixation between the prosthesis and the organs or tissue. (Boey, Para. [0049]).
Response to Arguments
Applicant’s arguments with respect to claim(s) 1, 2, and 8-15 have been considered but are moot in view of new ground(s) of rejection.
In response to the arguments on pages 4-6 of the remarks, the newly applied teaching reference, Boey et al. (US Pub. No.: 2012/0010636), teaches, in the same field of endeavor (hernia mesh), another side (bottom side) of a surgical mesh (combination of 10 and 20, Fig. 4 and Paras. [0047] and [0033]) consisting of an anti-adhesive polymer (anti-adhesive polymer layer 30, Fig. 4 and Para. [0050]-[0051]); wherein the anti-adhesive polymer comprises pectin (Para. [0050]).
Before the effective filing date of the claimed invention, it would have been obvious to one of ordinary skill in the art to modify the other side / another side of the surgical mesh of Zhang to consist of an anti-adhesive polymer serving as barrier, wherein the anti-adhesive polymer comprises pectin as taught by Boey in order to obtain the advantage of preventing any adhesion of prosthesis and organs or tissues to avoid undesired fixation between the prosthesis and the organs or tissue. (Boey, Para. [0049]).
