Claim Rejections – 35 U.S.C. 103
The following is a quotation of 35 U.S.C. 103 which forms the basis for all obviousness rejections set forth in this Office action:
A patent for a claimed invention may not be obtained, notwithstanding that the claimed invention is not identically disclosed as set forth in section 102, if the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to which the claimed invention pertains. Patentability shall not be negated by the manner in which the invention was made.
This application currently names joint inventors. In considering patentability of the claims the examiner presumes that the subject matter of the various claims was commonly owned as of the effective filing date of the claimed invention(s) absent any evidence to the contrary. Applicant is advised of the obligation under 37 CFR 1.56 to point out the inventor and effective filing dates of each claim that was not commonly owned as of the effective filing date of the later invention in order for the examiner to consider the applicability of 35 U.S.C. 102(b)(2)(C) for any potential 35 U.S.C. 102(a)(2) prior art against the later invention.
Claims 1, 2, 4, 5, 7-9 and 11 rejected under 35 U.S.C. 103 as being unpatentable over Tudorica (U.S. Patent Pub. No. 2016/0161098) of record, in view of Chakroborty (U.S. Patent Pub. No. 2009/0236619), in view of Anxu (CN 101325195, machine-translation provided).
Regarding Claim 1

Tudorica is silent with respect to “a silicone-based lens” including phosphor particles, emulsifier particles, and lens shaping particles each immersed within the silicone-based lens, wherein the emulsifier particles comprise a first hydrophobic compound and the lens shaping particles comprise a second compound different from the first hydrophobic compound, wherein the second compound forming the lens shaping particles comprise one or more of hydrophobic fumed silica, wherein the first hydrophobic compound defines a first weight percent by mass of lens and the second compound defines a second weight percent by mass of the silicone-based lens, and wherein the second weight percent is greater than the first weight percent”.
FIG. 8 of Chakroborty discloses a similar wavelength conversion device, comprising a silicone-based [0056] lens (806) optically coupled with the LED chip and including phosphor particles [0034], emulsifier particles, and lens shaping particles each immersed within the silicone-based lens, wherein the emulsifier particles comprise a first hydrophobic (inherent property) compound (TiO2) and the lens shaping particles comprise a second compound different from the first hydrophobic compound, wherein the second compound forming the lens shaping particles comprise one or more of hydrophobic (inherent property) fumed silica [0056], wherein the first hydrophobic compound defines a first weight percent by mass of lens and the second compound defines a second weight percent by mass of the silicone-based lens.
It would have been obvious to one of ordinary skill in the art before the effective filing of the claimed invention to modify the device of Tudorica, as taught by Chakroborty.
