Office Action

§102 §103
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 . 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. 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. 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: Plasma processing member in claim 1, disclosed as a plasma generator 250 in Fig 4. 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 § 102 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. Claim(s) 1-6 and 12 is/are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Kim et al. (US 20200185680). As to claims 1 and 12, Kim discloses a plasma processing apparatus/system (Abstract). Kim discloses that the apparatus comprises of a discharge roller; the discharge roller has a pattern portion on its outer surface comprising a stepped portion 254; said discharge roller having an inner space with a metal member 252 located therein; a plasma processing member 250 configured to generate plasma through a mutual reaction with the metal member (Fig. 4 below). PNG media_image1.png 407 419 media_image1.png Greyscale Expressions relating the apparatus to contents thereof during an intended operation are of no significance in determining patentability of the apparatus claim. Ex parte Thibault, 164 USPQ 666, 667 (Bd. App. 1969). A claim containing a “recitation with respect to the manner in which a claimed apparatus is intended to be employed does not differentiate the claimed apparatus from a prior art apparatus” if the prior art apparatus teaches all the structural limitations of the claim. Ex parte Masham, 2 USPQ2d 1647 (Bd. Pat. App. & Inter. 1987). Here, the apparatus of Kim contains all of the structural limitations of claims 1 and 12. As to claim 2, the apparatus of claim 1 is taught as seen above. Kim discloses that the pattern comprises of upper12b and lower portions 12a with a height difference relative to one another on the surface of the discharge roller (Fig. 5). As to claim 3, the apparatus of claim 2 is taught as seen above. Claim 3 is rejected for the same reasons as claim 2 above since the claim is drawn to method and materials worked upon limitations. As to claim 4, the apparatus of claim 2 is taught as seen above. Kim discloses that a connection portion 12c connect the upper and lower portions (Id.). As to claims 5 and 6, the apparatus of claim 2 is taught as seen above. Kim discloses that the upper and lower sections and are alternately arranged in a horizontal direction of the discharge roller on the outer surface of the discharge roller (Fig. 5). 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. Claim(s) 7-11 is/are rejected under 35 U.S.C. 103 as being unpatentable over Kim et al. (US 20200185680) in view of Yoshino (JPH 10309749). As to claim 7, the apparatus of claim 2 is taught as seen above. Kim fails to specifically teach or disclose that the lower portions are recessed relative to the outer surface of the discharge roller. Yoshino discloses a method for bonding materials with an apparatus that has discharge electrodes (Abstract). Yoshino discloses that it is known and conventional in the art to use a discharge roller with recesses in the surface of the roll so as to form intermittent bonding portions in the material processed (Fig. 5(a); pages 4-5). It would have been obvious to one of ordinary skill in the art at the time of filing to use the discharge roller surface of Yoshino in the apparatus taught by Kim because one of ordinary skill in the art would have been able to carry out such a substitution to achieve the predictable result of providing a known successful and conventional discharge roller surface for intermittent bonding in an apparatus with a discharge electrode. “The combination of familiar elements according to known methods is likely to be obvious when it does no more than yield predictable results.” KSR Int’l Co. v. Teleflex Inc., 127 S.Ct. 1727, 82 USPQ2d 1385 (2007). As to claim 8, the apparatus of claim 7 is taught as seen above. The recitation that the height difference between the upper and lower portions amounts to a size recitation which would have been obvious to one of ordinary skill in the art at the time of filing. In Gardner v. TEC Syst., Inc., 725 F.2d 1338, 220 USPQ 777 (Fed. Cir. 1984). As to claims 9-11, the apparatus of claim 1 is taught as seen above. The recited various patterns sizes, depths and mosaic shape would amount to amount a size recitation and shape recitation would have been obvious to one of ordinary skill at the time of the invention. Id.; In re Dailey, 357 F.2d 669, 149 USPQ 47 (CCPA 1966).
