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.
Claim(s) 1-4 is/are rejected under 35 U.S.C. 102(a)(1) as being anticipated by U.S. PGPub 2014/0093679 A1 by Okamoto.
Regarding claims 1, 2, Okamoto teaches a curable composition comprising a photopolymerizable compound and a photopolymerization initiator (¶[0098], [0099]), wherein the photopolymerizable compound contains a di(meth)acrylate having an oxypropylene group and a di(meth)acrylate having an oxyethylene group (examples given in ¶[0095] includes ethylene oxide-propylene oxide-modified bisphenol A di(meth)acrylate), and a mass ratio of a content of the oxypropylene group with respect to a content of the oxyethylene group in the photopolymerizable compound is 0.01 or more and 2.00 or less (an example of the most preferable ratio is 50/50, i.e., 1.0, ¶[0116]).
Regarding claim 3, Okamoto further teaches the composition may contain a filler such as titanium oxide (¶[0126]).
Regarding claim 4, since the claimed and prior art products are identical or substantially identical in structure or composition, a prima facie case of either anticipation or obviousness has been established and the coating taught by the prior art is presumed to be able to perform the function of a colored coating. In re Best, 562 F.2d 1252, 1255, 195 USPQ 430, 433 (CCPA 1977).
Allowable Subject Matter
Claims 5-8 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. Prior art of record fails to further teach or suggest a glass fiber having a core and a cladding, and two or more resin layers, one of which contains a cured product of the claimed resin composition, when considered in view of the rest of the limitations of the claimed invention.
Conclusion
The prior art made of record and not relied upon is considered pertinent to applicant's disclosure. US20220041501 discloses a related resin compound for optical fibers.
