Office Action

§103 §DP
Notice of Pre-AIA or AIA Status The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA . DETAILED ACTION A request for continued examination under 37 CFR 1.114, including the fee set forth in 37 CFR 1.17(e), was filed in this application after final rejection. Since this application is eligible for continued examination under 37 CFR 1.114, and the fee set forth in 37 CFR 1.17(e) has been timely paid, the finality of the previous Office action has been withdrawn pursuant to 37 CFR 1.114. Applicant’s submission filed on 3/21/26 has been entered. Response to Amendment The amendment is supported by the original claims and overcomes the previous 103 rejections. The text of those sections of Title 35, U.S. Code not included in this action can be found in a prior Office action. The previous restriction has been maintained. Claim Rejections - Double Patenting Claim(s) 1-14 is (are) rejected on the ground of nonstatutory obviousness-type double patenting as being unpatentable over claims 1-20 of US 11702539. ‘539 (claims 1-20) meets instant claims 1-14, because it discloses: PNG media_image1.png 200 400 media_image1.png Greyscale PNG media_image2.png 200 400 media_image2.png Greyscale PNG media_image3.png 200 400 media_image3.png Greyscale PNG media_image4.png 200 400 media_image4.png Greyscale PNG media_image5.png 200 400 media_image5.png Greyscale . The disclosed wholly aromatic LC polyester would inherently be thermotropic for meeting the claimed structures. The disclosed DK, DF, and melt viscosity overlap with the claimed ranges. It has been found that where claimed ranges overlap ranges disclosed by the prior art, a prima facie case of obviousness exists - see MPEP 2144.05. The disclosed compositions would be expected to feature the same deflection temperature, because ‘539 obviously satisfy all of the material and chemical limitations of the instant invention. As to the new limitation of “carbon fiber” in claim 1, ‘539 (claim 10) discloses the use carbon fibers as the conductive filler out of 6 candidates. The laundry list case law may apply to meet the claims. Claim(s) 1-14 is (are) rejected on the ground of nonstatutory obviousness-type double patenting as being unpatentable over claims 6-25 of US 11715579. ‘579 (claims 6-25) meets instant claims 1-14, because it discloses: PNG media_image6.png 200 400 media_image6.png Greyscale PNG media_image7.png 200 400 media_image7.png Greyscale PNG media_image8.png 200 400 media_image8.png Greyscale . The disclosed wholly aromatic LC polyester would inherently be thermotropic for meeting the claimed structures. The disclosed DK, DF, and melt viscosity overlap with the claimed ranges. It has been found that where claimed ranges overlap ranges disclosed by the prior art, a prima facie case of obviousness exists - see MPEP 2144.05. The disclosed compositions would be expected to feature the same deflection temperature, because ‘579 obviously satisfy all of the material and chemical limitations of the instant invention. As to the new limitation of “carbon fiber” in claim 1, ‘579 (claim 13) discloses the use carbon fibers as the conductive filler out of 6 candidates. The laundry list case law may apply to meet the claims. Claim Rejections - 35 USC § 103 Claim(s) 1-13, 15-17, and 20 is (are) rejected under 35 U.S.C. 103 as being unpatentable over Yung et al. (20130106659) in view of Lee et al. (US 5508374). As to claims 1-13, 15-17, and 20, Yung (claims, abs., Tables, 20-23, 37, 42-46, 53, 65-69, Ex.1, 8-9, 12) discloses a mold prepared from a composition comprising wholly aromatic and thermotropic 20-80 wt% (claim 1) of LC polymer (overlapping with the range of instant claim 4). The DK (claim 1) is greater than 4.4 (overlapping with the range of instant claim 1), and the Df (claim 19) is 0.0001 or 0.0055 (falling within the range of instant claim 1) measured at 2 GHz. The melting point (claim 1) is 250-440 °C (overlapping with the range of instant claim 2). The melt viscosity is 5-100 Pa-S (overlapping with the range of instant claim 1) measured at 350 °C at a shear rate of 1000 S-1 (claim 18) about 15 °C above the melting point of the LC copolymer. The deflection temperature (44) is 210 °C or 320 °C (falling within the range of instant claim 3) measured at 1.8 Mpa (68-69). The LC copolymer comprises 4-hydroxybenzoic acid, 17.5 mol% terephthalic acid, and 4,4’-biphenol, and 10 or more mol% (claim 27) overlapping with the range of instant claim 12) 2,6-hydroxynaphthoic acid. The composition comprises (claim 9, examples) Rutile TiO2 (exemplary loading of 15 wt% or 25 wt%, 87, falling within the range of instant claim 20) known to have a DK (1MHz) of around 100 (evidenced by Shinkosha website: https://www.shinkosha.com/english/product/epi_substrate/tio2/#:~:text=TiO2,Transmittance%20of%20Rutile%20(TiO2)), is used in the examples (Ex.12) as a filler to achieve the desired dielectric properties. PNG media_image9.png 1032 1089 media_image9.png Greyscale The It has been found that where claimed ranges overlap ranges disclosed by the prior art, a prima facie case of obviousness exists - see MPEP 2144.05. Yung is silent on the claimed carbon fiber. In the same area of endeavor of producing molds comprising a copolymer having anisotropic melt phase, Lee (claims, abs., Tables, 1: 15-25, 2:40-68, 4:30-40, Ex. I) discloses adding carbon fiber as reinforcing fiber. Therefore, as to claims 1-13, 15-17, and 20, it would have been obvious to one of ordinary skill in the art to have modified the composition disclosed by Yung and added carbon fiber as reinforcing fiber in view of Lee, because the resultant composition would yield improved reinforcement. The references are silent on the claimed Dk at 1MHz of claim 15. Accordingly, the examiner recognizes that not all of the claimed effects or physical properties are positively stated by the references. However, the references teach a composition containing the claimed components in the claimed amounts prepared by substantially similar components. Therefore, one of ordinary skill would have a reasonable expectation that the claimed effects and physical properties, i.e. Dk at 1MHz, would necessarily flow from a composition containing all of the claimed components in the claimed amounts prepared by a substantially similar process. Where the claimed and prior art products are identical or substantially identical in structure or composition, or are produced by identical or substantially identical processes, a prima facie case of either anticipation or obviousness has been established. See In re Best, 562 F.2d 1252, 1255, 195 USPQ 430, 433 (CCPA 1977); In re Spada, 911 F.2d 705, 709, 15 USPQ2d 1655, 1658 (Fed. Cir. 1990); see also MPEP § 2112.01(I)-(II). If it is the applicant’s position that this would not be the case: (1) applicant must provide evidence to support the applicant’s position, and (2) it would be the examiner’s position that the application contains inadequate disclosure on how to obtain the claimed effects or properties with only the claimed components in the claimed amounts by the disclosed or claimed process. Claim(s) 14 is (are) rejected under 35 U.S.C. 103(a) as being unpatentable over Yung et al. (20130106659) and Lee et al. (US 5508374) in view of Lee et al. (US 5508374 and further in view of Huspeni et al. (US 5492946). Disclosure of Yung and Lee is adequately set forth in ¶3 and is incorporated herein by reference. Yung further discloses increase naphthenic moiety on the LC copolymer would improve the electrical properties such as by reducing the dissipation factor. Yung and Lee is/are silent on the claimed ratio. In the same area of endeavor of producing molds comprising a LC copolymer and TiO2, Huspeni (claims, abs., Tables, 1:40, 13:1-55, 17:15-16, 22:32) discloses a thermotropic LC copolymer of 4-hydroxybenzoic acid, 2,6-hydroxynaphthoic acid, mol% terephthalic acid, and hydroquinone, wherein the molar ratio of 2,6-hydroxynaphthoic acid to 4-hydroxybenzoic acid is 1:9 to 9:1: PNG media_image10.png 200 400 media_image10.png Greyscale , overlapping with the claimed ranges The It has been found that where claimed ranges overlap ranges disclosed by the prior art, a prima facie case of obviousness exists - see MPEP 2144.05. Therefore, as to claim 14, it would have been obvious to one of ordinary skill in the art to have modified the process disclosed by Yung and further increase the mol% of 2,6-hydroxynaphthoic acid at a molar ratio of 2,6-hydroxynaphthoic acid to 4-hydroxybenzoic acid , e.g. about <9:1, in view of Huspeni, because the resultant composition would yield improved the electrical properties such as by reducing the dissipation factor. Response to Arguments The argument for allowance of amended claims has been fully considered but not persuasive. Applicant’s argument pertaining to the amendment has been rendered moot.
