Office Action

§101 §102 §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 . Claims 1-6, 11-13, and 15-16 are pending and examined on the merits. Claim Rejections - 35 USC § 101 35 U.S.C. 101 reads as follows: Whoever invents or discovers any new and useful process, machine, manufacture, or composition of matter, or any new and useful improvement thereof, may obtain a patent therefor, subject to the conditions and requirements of this title. Claims 1 and 11-13 are rejected under 35 U.S.C. 101 because the claimed invention is directed to a judicial exception without significantly more. The claim(s) recite(s) a peptide. This judicial exception is not integrated into a practical application. The claim(s) does/do not include additional elements that are sufficient to amount to significantly more than the judicial exception because Stymme et al. (U.S. Publication No. 20040073973) teach naturally occurring peptide SEQ ID NO: 2, comprising the instantly claimed peptide at residues 39-48 thereto, as it naturally occurs in nature without something more (note the filler of claims 11-13 may be naturally occurring equally as no substantive element is claimed): PNG media_image1.png 364 387 media_image1.png Greyscale 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 and 11-13 is/are rejected under 35 U.S.C. 102(a)(1) as being anticipated by: Stymme et al. (U.S. Publication No. 20040073973) which teach a peptide SEQ ID NO: 2, comprising the instantly claimed peptide at residues 39-48 thereto: PNG media_image1.png 364 387 media_image1.png Greyscale A product is a product. 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 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) 1-6, 11-13, 15-16 is/are rejected under 35 U.S.C. 103 as being unpatentable over: Stymme et al. (U.S. Publication No. 20040073973) which teach a peptide SEQ ID NO: 2, comprising the instantly claimed peptide at residues 39-48 thereto: PNG media_image1.png 364 387 media_image1.png Greyscale While Stymme does not expressly teach adding a protecting group (e.g. to the C-terminus, such a standard amine), the state of the art recognizes that protecting group addition is standard practice, and obvious to apply, when protection of any peptide is desired. Thus, adding a protecting group to any peptide, including a peptide comprising the instantly claimed peptide SEQ ID NO: 1 is deemed prima facie obvious. Additionally, as the peptide of Stymme is derived from plant tissue, applying such to the skin would have equally been prima facie obvious based on the protein application of plant tissue regularly in skin therapy. The amounts thereof being merely a matter of routine optimization (see MPEP 2144.05). Claim Rejections - 35 USC § 112(d) – Failure to Further Limit The following is a quotation of 35 U.S.C. 112(d): (d) REFERENCE IN DEPENDENT FORMS.—Subject to subsection (e), a claim in dependent form shall contain a reference to a claim previously set forth and then specify a further limitation of the subject matter claimed. A claim in dependent form shall be construed to incorporate by reference all the limitations of the claim to which it refers. Claims 12-13 are rejected under 35 U.S.C. 112(d) or pre-AIA 35 U.S.C. 112, 4th paragraph, as being of improper dependent form for failing to further limit the subject matter of the claim upon which it depends, or for failing to include all the limitations of the claim upon which it depends. The claims are directed to intended use without more than claim 11 to which they depend. Applicant may cancel the claim(s), amend the claim(s) to place the claim(s) in proper dependent form, rewrite the claim(s) in independent form, or present a sufficient showing that the dependent claim(s) complies with the statutory requirements. Claim Objections – Duplicate Claims Claims 11-13, without something more, are objected to under 37 CFR 1.75 as being a substantial duplicate of claim 1, as the peptide itself is a filler. When two claims in an application are duplicates or else are so close in content that they both cover the same thing, despite a slight difference in wording, it is proper after allowing one claim to object to the other as being a substantial duplicate of the allowed claim. See MPEP § 608.01(m). Conclusion Any inquiry concerning this communication or earlier communications from the examiner should be directed to MAURY AUDET whose telephone number is (571)272-0960.
