Office Action

§102 §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 . 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: “setting device” in claim 1 (inter alia) as well as “fixing device”. The term “device” is nonce or generic, modified by functions only (“setting” or “fixing”) respectively, and the claim does not contain sufficient structure to perform the entire function, therefore these are 112(f) interpreted limitations. 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 applicant regards as his invention. Claim limitation “setting device” in claim 1 (inter alia) as well as “fixing device” (claim 1, inter alia) invokes 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph (see above). However, the written description fails to disclose the corresponding structure, material, or acts for performing the entire claimed function and to clearly link the structure, material, or acts to the function. The disclosure does not depict the bounds or the actual structure that performs these functions and does not clearly delineate what is and is not encompassed by the term “fixing device” or “setting device” – it appears to be a catch-all for the functions described, and thus is not understood as a definition, or a description of a particular mechanism or a particular type of physical structure. Because the specification broadly and indefinitely references the claimed elements and does not put the public on fair notice as to their scope and meaning, Claims 1-12 are indefinite and are rejected under 35 U.S.C. 112(b) or pre-AIA 35 U.S.C. 112, second paragraph. Applicant may: (a) Amend the claim so that the claim limitation will no longer be interpreted as a limitation under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph; (b) Amend the written description of the specification such that it expressly recites what structure, material, or acts perform the entire claimed function, without introducing any new matter (35 U.S.C. 132(a)); or (c) Amend the written description of the specification such that it clearly links the structure, material, or acts disclosed therein to the function recited in the claim, without introducing any new matter (35 U.S.C. 132(a)). If applicant is of the opinion that the written description of the specification already implicitly or inherently discloses the corresponding structure, material, or acts and clearly links them to the function so that one of ordinary skill in the art would recognize what structure, material, or acts perform the claimed function, applicant should clarify the record by either: (a) Amending the written description of the specification such that it expressly recites the corresponding structure, material, or acts for performing the claimed function and clearly links or associates the structure, material, or acts to the claimed function, without introducing any new matter (35 U.S.C. 132(a)); or (b) Stating on the record what the corresponding structure, material, or acts, which are implicitly or inherently set forth in the written description of the specification, perform the claimed function. For more information, see 37 CFR 1.75(d) and MPEP §§ 608.01(o) and 2181. Claim 8 additionally recites that the carrier is controlled in a “force controlled manner” which is indefinite in this context. What is needed to be force controlled? Is the presence or possibility of force application sufficient? The structure and arrangement being claimed is not clear in this manner—the specification indicates also that “ As a consequence, it is possible that the knife carrier can be moved by means of the setting device parallel to the axis of rotation into a cutting position, in particular in a force-controlled manner, wherein the knife carrier is reliably secured in the cutting position by means of the fixing device. It is here accepted that no force-controlled regulation of the cutting force is possible during the cutting process.” Which appears contradictory—Applicant appears to say that force control is possible and also not possible, and therefore the nature of the claimed “force controlled…” is not clear. Claim 12 additionally recites that the carrier is mounted so that it “cannot be adjusted orthogonally…” which is not understood—the device as shown in the application can, under some circumstances, be adjusted orthogonally, in that intersxtitial members can be added, or it could be whacked with a hammer… etc. The claim limitation is therefore not reasonably precise and clear with respect to the construction of the device, and it is at least partially inaccurate. 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. Claim(s) 1-12 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Supe-Dienes (DE 102 60 031). Figures 1-4 of Supe-Dienes clearly show the same invention and structures as presently claimed in claims 1-12 (noting the indefiniteness of claims 1, 8, 12 especially—to the extent the claims are understood, the Supe-Dienes shows these features in the same manner as applicant) Conclusion Any inquiry concerning this communication or earlier communications from the examiner should be directed to SEAN M MICHALSKI whose telephone number is (571)272-6752.
