Office Action

§112
DETAILED ACTION 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 . Response to Amendment Withdrawn Rejections The 35 U.S.C. 112(b) rejection of claims 8, 15-26 is withdrawn due to Applicant’s amendment in the response filed on May 13, 2026. The 35 U.S.C. 102(a/1,2) and 35 U.S.C. 103 rejections of claims 1-7 over Kuwana as the primary reference, are withdrawn due to Applicant’s amendment in the response filed on May 13, 2026. The 35 U.S.C. 103 rejection of claims 15-18, 26 over Bae in view of Kuwana, is withdrawn due to Applicant’s amendment in the response filed on May 13, 2026. New Objection/Rejections Claim Objection Claim 15 is objected to because of the following informalities. Line 7 should be rewritten as: - - wherein the light control part comprises a first light control part, a second light control part - -. Appropriate correction is required. Claim Rejections - 35 USC § 112 The text of those sections of Title 35, U.S. Code not included in this action can be found in a prior Office action. Claims 1, 3, 5-15,17-19 and 21-26 are rejected under 35 U.S.C. 112(b) as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor regards as the invention. Regarding claim 1, it is unclear in lines 2-4, whether the first light control part, the second light control part and the third light control part, are discrete domains in the light control member, which are visually distinct from each other, or are randomized on the microscopic or nanoscopic level in the light control member. It is also unclear whether the liquid crystal ligands in line 11, are the plurality of the liquid crystal ligand in line 9, because if that were the case, then it is further unclear how the first, second and third light control parts can be discrete domains in the light control member. Claims 3, 5-14 depend on and contain all the subject matter of claim 1, but fail to provide any solutions to the indefinite issues described above. Regarding claim 15, it is unclear in lines 7-8, whether the first light control part, the second light control part and the third light control part, are discrete domains in the light control part, which are visually distinct from each other, or are randomized on the microscopic or nanoscopic level in the light control part. It is also unclear whether the liquid crystal ligands in line 16, are the plurality of the liquid crystal ligand in line 14, because if that were the case, then it is further unclear how the first, second and third light control parts can be discrete domains in the light control part. Claims 17-19 and 21-26 depend on and contain all the subject matter of claim 15, but fail to provide any solutions to the indefinite issues described above. Clarification and/or amendment, accompanied by relevant citation(s) from the specification and/or teaching references are required.
