DETAILED ACTION
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.
Claims 12 to 22 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Okamura et al. 2016/0379817.
Okamura et al. teach polysilazanes. Paragraph 19 and on exemplify the repeat-
ing units that are the same as those found in claim 14. Of particular importance see Table 1, paragraph 28 and 29, which show a polysilazane having an SiH3 ratio of .051 and an NH ratio of .042 in a 17% by mass solution in xylol (xylene). This anticipates claims 12 and 17.
For claims 13 and 14, note from the units shown in Table 1, as well as the units shown in paragraph 20, that this is a perhydropolysilazane.
For claim 15, see the molecular weights in paragraph 24 which fall within this range.
For claim 16, on one hand, note that this is a product by process claim such that this process need not be specifically taught for the product to be met.
On the other hand, see the method by which the polysilazane of Okamura et al. are prepared. For instance paragraph 39 teaches reacting dichlorosilane, meeting formula (1), with ammonia in the presence of a solvent. While this does not specifically state that the solvent meets the claimed relative dielectric constant, the two solvents specifically taught in paragraph 39 meet this requirement (dichloromethane 8.9 at 25oC; benzene 2.28 at 20oC).
For claim 18, note that above regarding the process and paragraph 39, as it currently applies.
For claims 19 to 22, see paragraphs 49 and on which teach a method for forming a siliceous film. Note that paragraph 51 teaches electronic devices. Also note that para-graphs 55 to 57, among others, teach preparing the film in the presence of water vapor, i.e. steam.
