Office Action

§112
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 Response to Amendment Applicant's amendments filed on 06/15/2026 have been entered. Claims 1, 5-11 and 15-20 currently under examination on the merits. Any rejections and/or objections made in the previous Office action and not repeated below are hereby withdrawn. Claim Rejections - 35 USC § 112 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. Claims 1, 5-11 and 15-20 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 pre-AIA the applicant regards as the invention. Claims 1 and 11 are rejected as being vague and indefinite when these claims recite "R is selected from a substituted or unsubstituted alkyl group with a number of carbon atoms of 2 to 20, a substituted or unsubstituted siloxane group with a number of carbon atoms ranging from 2 to 20, or an alkyl amide group with a number of carbon atoms ranging from 2 to 20”, and “wherein a structure general formula of R is -(CH2)m-(R1)(R2)R3, R1, R2, R3, are individually selected from F or H, and at least one of R1, R2, R3, is selected from F, and n is an integer ranging from 1 to 19” to further limit R being a species; which render more than one range in the same claim. A broad range or limitation together with a narrow range or limitation that falls within the broad range or limitation in the same claim is considered indefinite, since the resulting claim does not clearly set forth the metes and bounds of the patent protection desired. See MPEP § 2173.05(c). claims 5-10 and 15-20 are also rejected for depending from claims 1 and 11. Allowable Subject Matter Claims 1, 5-11 and 15-20 would be allowable if rewritten to overcome 112 rejections as set forth above and including all of the limitations of the base claim and any intervening claims. The reason for the allowance is that the prior art of record does not discloses or fairly suggest a polarizer and a liquid crystal display device as recited in the present claims 1 and 11, wherein the modified group is -X-A-R, in which X is SO3 or PO4H; A is a single bond, a substituted or unsubstituted aromatic group with a number of ring atoms ranging from 6 to 20, or an imidazoline group; R is -(CH2)m-(R1)(R2)R3, in which R1, R2, R3, each is F or H, and at least one of R1, R2, R3, is F, and n is an integer ranging from 1 to 19. Conclusion Applicant's amendment necessitated the new ground(s) of rejection presented in this Office action. Accordingly, THIS ACTION IS MADE FINAL. See MPEP § 706.07(a). Applicant is reminded of the extension of time policy as set forth in 37 CFR 1.136(a). A shortened statutory period for reply to this final action is set to expire THREE MONTHS from the mailing date of this action. In the event a first reply is filed within TWO MONTHS of the mailing date of this final action and the advisory action is not mailed until after the end of the THREE-MONTH shortened statutory period, then the shortened statutory period will expire on the date the advisory action is mailed, and any nonprovisional extension fee (37 CFR 1.17(a)) pursuant to 37 CFR 1.136(a) will be calculated from the mailing date of the advisory action. In no event, however, will the statutory period for reply expire later than SIX MONTHS from the mailing date of this final action.
