Office Action

§102 §112
DETAILED ACTION Notice of Pre-AIA or AIA Status 1. The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA . Claim Rejections - 35 USC § 112 2. 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. 3. Claims 1-2 are 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 applications subject to pre-AIA 35 U.S.C. 112, the applicant), regards as the invention. Claim 1 recites the limitation "the core" in line 16. There is insufficient antecedent basis for this limitation in the claim. It is unclear from the claim whether the phrase “the core” is referred to “a high frequency dielectric material core” or not. Claim 1 recites the limitation "the copper layer" in line 30. There is insufficient antecedent basis for this limitation in the claim. It is unclear whether “the copper layer” is referred to “an electrolytic copper layer” or “thin seed copper layer”. Claim 2 is rejected under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), second paragraph because it depends on indefinite claim 1. Claim Rejections - 35 USC § 102 4. In the event the determination of the status of the application as subject to AIA 35 U.S.C. 102 and 103 (or as subject to pre-AIA 35 U.S.C. 102 and 103) is incorrect, any correction of the statutory basis (i.e., changing from AIA to pre-AIA ) for the rejection will not be considered a new ground of rejection if the prior art relied upon, and the rationale supporting the rejection, would be the same under either status. 5. 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. (a)(2) the claimed invention was described in a patent issued under section 151, or in an application for patent published or deemed published under section 122(b), in which the patent or application, as the case may be, names another inventor and was effectively filed before the effective filing date of the claimed invention. 6. Claim 3 is rejected under 35 U.S.C. 102(a)(1) and/or 102(a)(2) as being anticipated by Leng (US 2022/0271117 A1). As to claim 3, Leng discloses a thin film resistor wherein the thin film resistor (TFT 220a) is located between copper conductors (210, 264a) wherein there is not thin film resistor material is located under the copper conductors (See paragraph 0038-0041, Fig 2). 7. Claim 3 is rejected under 35 U.S.C. 102(a)(1) and/or 102(a)(2) as being anticipated by Ku (US 2022/0102271 A1). As to claim 3, Ku discloses a thin film resistor wherein the thin film resistor (111) is located between copper conductors (112 or 113 and 109) wherein there is not thin film resistor material is located under the copper conductors (See paragraph 0018, 0028-0029, 0032, Fig 1). Allowable Subject Matter 8. Claim 1 would be allowable if rewritten or amended to overcome the rejection(s) under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), 2nd paragraph, set forth in this Office action. 9. Claim 2 would be allowable if rewritten to overcome the rejection(s) under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), 2nd paragraph, set forth in this Office action and to include all of the limitations of the base claim and any intervening claims. 10. The following is a statement of reasons for the indication of allowable subject matter: The cited prior arts fail to disclose r) etching the copper layer that was below the developed unexposed portions of the third imageable resist material layer to reveal the thin film resistor material; s) removal of the exposed portions of the third imageable resist material layer to create a selective thin film resistor located between copper conductors in combination with all other limitations in the claim. The closest prior arts Ku discloses forming thin film resistor (111) between copper conductors (112 or 113 and 109) without using a third imageable resist material. Conclusion 11.
