Office Action

§103 §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and the fee set forth in 37 CFR 1.17(e) has been timely paid, the finality of the previous Office action has been withdrawn pursuant to 37 CFR 1.114.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 05/12/26 has been entered. Specification The amendments the specification address the trademark have been entered and are sufficient to get around the objection. The specification is objected to as failing to provide proper antecedent basis for the claimed subject matter. See 37 CFR 1.75(d)(1) and MPEP § 608.01(o). Correction of the following is required: support for “anti-viral” as amended into claims 1 and 14 needs to be provided in the specification. 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 applicant regards as his invention. Claims 1 and 14 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. Claims 1 and 14 detail the agent to be an “anti-viral”, however, the specification is silent to this term and fails to define what agents this would include. Any remaining claims are rejected depending from a rejected base claim. 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. Claim(s) 1-5, 8 and 14 is/are rejected under 35 U.S.C. 103 as being unpatentable over Johnson (US 2014/0223630) in view of Rios et al. (US 2010/0183814). In regard to claim 1, Johnson teaches a sock (sock: 10) or shoe cover comprising: a tubular sock body comprising a body (see figures 1 and 2), a closed end (see closed end), an opposing open foot-receiving end (opposing end of sock from closed end: figures 1 and 2), a dorsal face (top of sock: figures 1 and 2), and a surface contact face (bottom of sock: figures 1 and 2); at least one grip feature presented on at least the surface contact face (grip segments: 24, figures 1 and 2; paragraph 0029); and at least one antimicrobial agent distributed, dispersed, or dissolved in at least one grip feature (paragraph 0030 and 0031). It is noted that the sock body being knitted is a product by process limitation (see MPEP 2113), therefore, the method of making the sock of the prior art is not germane to patentability of the prior art final sock product taught by the prior art. Johnson teaches the tubular sock final garment sock structure (see figure 2-3). However, Johnson fails to teach the agent being an antiviral. Rios et al. (US 20100183814) teaches a friction rubber grip for the bottom of a sock (paragraph 0141), wherein the grip is provided with antiviral agents (paragraph 0059 and 0114). It would have been obvious to one having ordinary skill in the art before the effective filing date to have provided the rubber grip feature of Johnson with an anti-viral agent as taught by Rios et al., since the rubber grip feature of Johnson provided with an anti-viral agent would provide a grip feature that protects against viruses. In regard to claim 2, Johnson teaches wherein the at least one grip feature comprises one grip feature or a plurality of grip features (grip segments: 24, Figures 1 and 2). In regard to claim 3, Johnson teaches further comprising at least one grip feature presented on the dorsal face (see grip segments: 24 in figures 1 and 2). In regard to claim 4, Johnson teaches wherein the at least one grip feature is bonded to the surface contact face (paragraph 0029). In regard to claim 5, Johnson teaches wherein the at least one grip feature is presented on at least one of a heel portion, a plantar portion, and a lateral portion of the tubular sock body when donned (see grip segments: 24 in figures 1 and 2). In regard to claim 8, the combined references teach wherein one or more of the at least one agent is selected from silver, copper, tin, nickel, zinc, sodium, or their cations (Rios et al.: paragraph 0114). It would have been obvious to one having ordinary skill in the art before the effective filing date to have provided the rubber grip feature of Johnson with the silver antimicrobial agent as taught by Rios et al., since the rubber grip feature of Johnson provided with a silver antimicrobial agent would provide powerful antimicrobial agent to destroy bacteria. In regard to claim 14, Johnson teaches a sock or shoe cover comprising: a sock body (sock: 10) comprising a tubular body a closed toe end (closed toe end), a heel area (heel area), and a foot or shoe receiving opening (opening 20), a first grip portion of a plurality of grip features (grip segments: 24, paragraph 0029); and at least one antimicrobial agent distributed, dispersed or dissolved in at least some of the plurality of grip features (paragraphs 0030-0031). It is noted that the sock body being knitted is a product by process limitation (see MPEP 2113), therefore, the method of making the sock of the prior art is not germane to patentability of the prior art final sock product taught by the prior art. Johnson teaches the tubular sock final garment sock structure (see figure 2-3). However, Johnson fails to teach the agent being an antiviral. Rios et al. (US 20100183814) teaches a friction rubber grip for the bottom of a sock (paragraph 0141), wherein the grip is provided with antiviral agents (paragraph 0059 and 0114). It would have been obvious to one having ordinary skill in the art before the effective filing date to have provided the rubber grip feature of Johnson with an anti-viral agent as taught by Rios et al., since the rubber grip feature of Johnson provided with an anti-viral agent would provide a grip feature that protects against viruses. Claim(s) 10-11 and 13 is/are rejected under 35 U.S.C. 103 as being unpatentable over Johnson (US 2014/0223630) in view of Rios et al. (US 2010/0183814) as applied to claim 1 above, and further in view of Yan et al. (US 6,979,491). Johnson and Rios et al. teaches a sock garment with friction grip as described above in claim 1. However, Johnson and Rios et al. fail to teach further comprising an antimicrobial yarn and comprising a sock body antimicrobial agent, the sock body antimicrobial agent being integral with a material forming the tubular sock body. In regard to claim 10, Yan et al. teaches a sock garment composed of an antimicrobial yarn (see abstract). It would have been obvious before the effective filing date to one having ordinary skill in the art to have provided the sock yarn forming the sock of Johnson to be an antimicrobial yarn as taught by Yan et al., since the sock yarn forming the sock of Johnson being antimicrobial would provide a sock that has antimicrobial properties embedded in the yarn making up the sock, keeping bacteria at bay. In regard to claim 11, Johnson teaches wherein the grip feature is selected from homopolymers or copolymers comprising poly ethylene vinyl acetate, poly vinyl chloride, polyurethane, synthetic or natural rubber, styrene-butadiene, and isoprene (paragraph 0029). In regard to claim 13, Yan et al. teaches a sock garment wherein the sock body has an antimicrobial agent, the sock body antimicrobial agent being integral with a material forming the tubular sock body (see abstract). It would have been obvious before the effective filing date to one having ordinary skill in the art to have provided the sock yarn forming the sock of Johnson to be an antimicrobial yarn as taught by Yan et al., since the sock yarn forming the sock of Johnson being antimicrobial would provide a sock that has antimicrobial properties embedded in the yarn making up the sock, keeping bacteria at bay. Response to Arguments Applicant’s arguments with respect to the claims have been considered but are moot because the new ground of rejection does not rely on any reference applied in the prior rejection of record for any teaching or matter specifically challenged in the argument. Conclusion The prior art made of record and not relied upon is considered pertinent to applicant's disclosure and can be found cited in PTO-892 form submitted herewith. The cited prior art to O et al. (US 12,209,344) is of particular relevance to the claimed invention.
