Office Action

§102 §112
CTNF 18/289,626 CTNF 70775 Notice of Pre-AIA or AIA Status 07-03-aia AIA 15-10-aia The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA. This office action is responsive to the Reopening of Prosecution on 29 April 2026 due to consideration of an Information Disclosure Statement filed 22 April 2026 subsequent to the mailing of a Notice of Allowance on 2 March 2026. Claims 1-3, 5-8, and 10-18 remain pending and presently under consideration in this application. Application Status 13-05 AIA Applicant is advised that the Notice of Allowance mailed 2 March 2026 is vacated. If the issue fee has already been paid, applicant may request a refund or request that the fee be credited to a deposit account. However, applicant may wait until the application is either found allowable or held abandoned. If allowed, upon receipt of a new Notice of Allowance, applicant may request that the previously submitted issue fee be applied. If abandoned, applicant may request refund or credit to a specified Deposit Account. 13-04 Prosecution on the merits of this application is reopened on claims considered unpatentable for the reasons indicated below. 07-06 AIA 15-10-15 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. Claim Rejections - 35 USC § 102 07-07-aia AIA 07-07 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 – 07-08-aia AIA (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. 07-15 AIA Claim s 1-3, 5-8, 10-18 are rejected under 35 U.S.C. 102( a)(1 ) as being anticipated by Poetsch et al. (U.S. Patent Application Publication No. 2006/0166033, which is the English language equivalent of WO 2004/003102 cited in the IDS of 22 April 2026 ) . Poetsch et al. teaches a compound, the corresponding use thereof said compound in a mixture further comprising a solvent and/or additive, such as a reactive mesogen, the corresponding polymer obtained by polymerizing said compound, as well as the corresponding use thereof said compound in a device, characterized in that said compound is inclusive of the compound of the general formula I , as generally represented therein by PNG media_image1.png 118 384 media_image1.png Greyscale ([0042], p. 2) when Q is PNG media_image2.png 162 375 media_image2.png Greyscale [0050], as well as a compound inclusive of the compound of the subformula I-6 / I-6-1 / I-6-2 , as generally represented therein by PNG media_image3.png 180 828 media_image3.png Greyscale ([0067], p. 4) , and more specifically as represented therein by PNG media_image4.png 785 656 media_image4.png Greyscale and PNG media_image5.png 188 640 media_image5.png Greyscale ([0085], p. 6) . Claim Rejections - 35 USC § 112 07-30-02 AIA 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. 07-34-01 Claim 6 is 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 6 is rejected as being vague and indefinite when it recites each of the formulae I-5-1 through I-5-5, and I-6-1 through I-6-5; the scope of the protection sought is not clear, as claim 6 fails to particularly point out and distinctly claim the definition of the substituent L therein, or that the substituent L is as recited in claim 1. The Examiner notes that applicants amended claim 6 to delete the definition of the substituent L.
