Claim Rejections - 35 USC § 112
The following is a quotation of the first paragraph of 35 U.S.C. 112(a):
(a) IN GENERAL.—The specification shall contain a written description of the invention, and of the manner and process of making and using it, in such full, clear, concise, and exact terms as to enable any person skilled in the art to which it pertains, or with which it is most nearly connected, to make and use the same, and shall set forth the best mode contemplated by the inventor or joint inventor of carrying out the invention.
Claim 21 is rejected under 35 U.S.C. 112(a) or 35 U.S.C. 112 (pre-AIA ), first paragraph, as failing to comply with the written description requirement. The claim(s) contains subject matter which was not described in the specification in such a way as to reasonably convey to one skilled in the relevant art that the inventor or a joint inventor, or for applications subject to pre-AIA 35 U.S.C. 112, the inventor(s), at the time the application was filed, had possession of the claimed invention.
There does not appear to be a written description of the claim limitation “wherein the encapsulant comprises a single layer of the resin” (new claim 21) (emphasis added) in the application as filed.
Applicant must cancel the un-support new matters in response to the Office 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 Rejections - 35 USC § 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.
Claim 16 is rejected under 35 U.S.C. 103 as being unpatentable over HABA ‘121 as applied to claim 1 above, and further in view of ECTON et al. (US. Pub. No. 2019/0304912).
HABA teaches the printed circuit board as described in claim 1 above including: plurality of metal wire (102) disposed in the encapsulant.
Thus, HABA is shown to teach all the features of the claim with the exception of explicitly disclosing the metal wires comprising gold.
However, ECTON teaches a printed circuit board including: plurality of metal wire (111) disposed in the encapsulant, wherein the plurality of metal wires (111) comprising gold. (See FIG. 1).
Therefore, it would have been obvious to one having ordinary skill in the art at the time of invention was made to form the interconnect structure of HABA utilizing metal wires comprising gold or any other metals as taught by ECTON for the same intended purpose of providing electrical connections between the chips.
Further, it has been held to be within the general skill of a worker in the art to select a known material on the basis of it suitability for the intended use as a matter of obvious design choice. In re Leshin, 125 USPQ 416., 125 USPQ 416.
