Claim Rejections - 35 USC § 112
8. 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.
9. Claim 3 is 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 3 recites “the hydroxyl-terminated polydimethylsiloxane in the A phase has a viscosity of 950 Pa.s to 1,050 Pa.s.”, wherein applicant fails to articulate by sufficiently distinct functional language, the required temperature in which viscosity is measured, since viscosity is a measure of a fluid's resistance to flow, influenced by factors such as temperature. Thus, claim 3 constitutes indefinite subject matter as per the metes and bounds of said phrase engenders indeterminacy in scope.
10. Claim 4 is 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 4 recites “the dispersants in the A phase, the B phase and the C phase are all methyl silicone oil having a viscosity of 9,900 Pa·s to 10,100 Pa·s.”, wherein applicant fails to articulate by sufficiently distinct functional language, the required temperature in which viscosity is measured, since viscosity is a measure of a fluid's resistance to flow, influenced by factors such as temperature. Thus, claim 4 constitutes indefinite subject matter as per the metes and bounds of said phrase engenders indeterminacy in scope.
Claim Rejections - 35 USC § 102
11. 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.
12. Claims 1-8 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Xie et al. (CN 117304696 A, machine translation, hereinafter “’696”).
