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 Objections Claim 10 is objected to because of the following informalities: Claim 10 Ln 1-3, states the terms “a second structure”, “a first structure”, “an axis”, “an axial direction”, “a space” and “a penetrator”. All of these terms were previously stated in claim 1. These subsequently stated terms should be prefixed with ‘the’ instead of ‘a/an’. Claim Rejections - 35 USC § 112 The following is a quotation of 35 U.S.C. 112(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 1-20 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 pre-AIA the applicant regards as the invention. Claim 1 Ln 7 states the limitation "a first sealing flange to seal a space between the first sealing flange and the second structure”. It is unclear how the first sealing flange seals a space between itself and the second structure. If there is a space between itself and the second structure than how is it sealed? Therefore, the scope of the claim is indeterminate. For examination, the limitation was interpreted as --a first sealing flange to seal by contacting Claim 6 Ln 2 states the limitation "the second distance”. This limitation lacks antecedent basis and it is unclear to which previous structure it is referring. Therefore, the scope of the claim is indeterminate. For examination, claim 5, upon which claim 6 is dependent, was interpreted as being dependent upon claim 4. Claim 8 Ln 2 states the limitation "the protruding portion seals a space between the protruding portion and the first structure”. It is unclear how the protruding portion seals a space between itself and the first structure. If there is a space between itself and the first structure than how is it sealed? Therefore, the scope of the claim is indeterminate. For examination, the limitation was interpreted as --the protruding portion seals by contacting Claim 12 Ln 2-4 states the limitation "the first annular portion including, at an end of the first annular portion in a first direction along the axis, a first sealing flange protruding radially outward”. When taken in light of the specification, it appears that the first sealing flange is not located at the first end of the first annular portion, but is instead located at the second end approximate the connecting portion. Furthermore, Ln 6 states the limitation “a connecting portion connecting ends of the first annular portion to the second”. It is unclear if these ‘ends’ are distinct from the ‘end’ of Ln 2. Therefore, the scope of the claim is indeterminate. For examination, the limitation was interpreted as -- the first annular portion including, at an end of the first annular portion in a direction opposite a first direction along the axis, a first sealing flange protruding radially outward-- and --a connecting portion connecting [[ends]] the end of the first annular portion to an end of the second--, respectively. Claim 20 Ln 2 states the limitation "the protruding portion seals a space between the protruding portion and the first structure”. It is unclear how the protruding portion seals a space between itself and the first structure. If there is a space between itself and the first structure than how is it sealed? Therefore, the scope of the claim is indeterminate. For examination, the limitation was interpreted as --the protruding portion seals by contacting Claims 2-5, 7, 9-11 and 13-19 are rejected for their dependence upon a rejected parent 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. -(a)(2) the claimed invention was described in a patent issued under section 151, or in an application for patent published or deemed published under section 122(b), in which the patent or application, as the case may be, names another inventor and was effectively filed before the effective filing date of the claimed invention.
