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 . Election/Restrictions Claims 7-17 are withdrawn from further consideration pursuant to 37 CFR 1.142(b) as being drawn to a nonelected method, there being no allowable generic or linking claim. Election was made without traverse in the reply filed on 3/31/26. New claims 18-20 have been entered. Currently claims 1-6 and 18-20 are pending. 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 18-20 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 18 recites the limitation "the fill stem" in line 3. There is insufficient antecedent basis for this limitation in the claim. 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) 1-3 and 18 is/are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Hayashi et al. (JPH0610007). Regarding Claim 1, Hayashi et al. discloses a canister 1 (figure 1) for hot isostatic pressing, the canister comprising: a body 3 (figure 1) arranged to define a cavity (figure 1) for containing a powder arranged to be subjected to hot isostatic pressing; and an opening (figure 1, when lid removed) defined in the body through which a powder can be inserted into the body (paragraph 9), and the opening being closeable so as to seal the canister for hot isostatic pressing (paragraph 9); wherein the body comprises a weakened area 5a/5b (figure 1), the weakened area defining a part of the body which is designed to dissolve in acid faster than the rest of the body (figure 1). Regarding Claim 2, Hayashi et al. discloses the body comprises a plurality of weakened areas 5a/5b (figure 1). Regarding Claim 3, Hayashi et al. discloses the weakened area comprises a notch formed in the body 5a/5b (Figure 1). Regarding Claim 18, Hayashi et al. discloses a method for hot isostatic pressing a powdered material (paragraph 9), the method comprising: disposing at least one powdered material (paragraph 9) in the canister of claim 1 (paragraph 8); evacuating at least a portion of air from the canister through the fill stem (paragraph 9); hermetically sealing the canister (paragraph 9); and, hot isostatically pressing the canister (paragraph 9). Applicant is duly reminded that a complete response must satisfy the requirements of 37 C.F. R. 1.111, including: “The reply must present arguments pointing out the specific distinctions believed to render the claims, including any newly presented claims, patentable over any applied references. A general allegation that the claims “define a patentable invention” without specifically pointing out how the language of the claims patentably distinguishes them from the references does not comply with the requirements of this section. Moreover, “The prompt development of a clear Issue requires that the replies of the applicant meet the objections to and rejections of the claims.” Applicant should also specifically point out the support for any amendments made to the disclosure. See MPEP 2163.06 II(A), MPEP 2163.06 and MPEP 714.02. The ''disclosure'' includes the claims, the specification and the drawings. Allowable Subject Matter Claims 4-6 are objected to as being dependent upon a rejected base claim, but would be allowable if rewritten in independent form including all of the limitations of the base claim and any intervening claims.
