Office Action

§101 §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 . Priority Receipt is acknowledged of certified copies of papers required by 37 CFR 1.55. Drawings The drawings were received on 09/30/2024. These drawings are approved. 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 6 and 7 are rejected under 35 U.S.C. 101 because the claimed invention is not supported by either a specific and substantial asserted utility or a well-established utility. In Claim 6, the claim is drawn to a rhenium-tungsten alloy wire with a use that is non-statutory no method or process steps are recited. In Claim 7, the method has no steps and thus lacks the concrete operational steps required to define how it works or integrate it into a practical application. Claim Rejections - 35 USC § 112 The following is a quotation of the first paragraph of 35 U.S.C. 112(a): (a) IN GENERAL —The specification shall contain a written description of the invention, and of the manner and process of making and using it, in such full, clear, concise, and exact terms as to enable any person skilled in the art to which it pertains, or with which it is most nearly connected, to make and use the same, and shall set forth the best mode contemplated by the inventor or joint inventor of carrying out the invention. The following is a quotation of the first paragraph of pre-AIA 35 U.S.C. 112: The specification shall contain a written description of the invention, and of the manner and process of making and using it, in such full, clear, concise, and exact terms as to enable any person skilled in the art to which it pertains, or with which it is most nearly connected, to make and use the same, and shall set forth the best mode contemplated by the inventor of carrying out his invention. Claims 6 and 7 are also rejected under 35 U.S.C. 112(a) or pre-AIA 35 U.S.C. 112, first paragraph (see above under 35 USC § 101). Specifically, because the claimed invention is not supported by either a specific and substantial asserted utility or a well-established utility for the reasons set forth above, one skilled in the art clearly would not know how to use the claimed invention. 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 1-7 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. Claim 1 recites “a ratio W/Re of an atomic concentration … according to XPS analysis is 2.5 or more” in lines 3-5. “XPS” is defined in the specification as X-ray photoelectron spectroscopy [0006]. This limitation is clear. However, it is unclear how “in an arbitrary measurement area of a unit area” relates to what is happening at the wire surface. Claims dependent on any of the rejected claims are likewise rejected under this statute. Allowable Subject Matter Claims 1-5 and 8 would be allowable if rewritten or amended to overcome the rejection(s) under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), 2nd paragraph, set forth in this Office action. Claims 6 and 7 are not in allowable form as indicated above based on the rejections under 35 U.S.C. 101 and 35 U.S.C. 112(a). The following is a statement of reasons for the indication of allowable subject matter: Honda et al (US 4,973,880) teaches a tungsten-rhenium wire but does not teach the wire has a concentration ration of W/Re at the surface as claimed.
