Allowable Subject Matter
Claim 19 is objected to as being dependent upon a rejected base claim, but would be allowable if rewritten in independent form including all of the limitations of the base claim and any intervening claims.
The following is a statement of reasons for the indication of allowable subject matter:
With regards to Claim 19, the prior art of record fails to disclose or fairly suggest the transparent film is in contact with the lower surface of the reflective film, and the reflective film is spaced apart from the light transmitting layer, in combination with the remaining limitations of the claim from which Claim 19 depends.
Response to Arguments
Applicant's arguments filed 9/24/2026 have been fully considered but they are not persuasive.
With regards to the applicant’s argument that the limitations of Claim 15 are shown in Figure 1 because Figure 1 shows the plurality of holes [155] disposed in the first region [A1] and the third region [A3], and the interval between adjacent holes [155] in the third region [A1] is different from the interval between adjacent holes [155] in the third region [A3], the examiner notes that Claim 15 recites on lines 3-4 “a region with a smaller interval between holes among the regions is closer to the light source than a region with a larger intervals between holes”. Figure 1 does not appear to show a region with a smaller interval between holes being closer to the light source than a region with a larger interval between holes. Therefore, the above Drawing Objection has not been overcome.
With regards to the applicant’s argument pertaining to amended Claim 1 and to Claim 13 that Chen and Jeong et al. do not teach or suggest the reflective layer includes a transparent film and the transparent film is disposed on at least one of the upper and lower surfaces of the reflective film, and Sumitani does not disclose the claimed transparent film covering the plurality of holes, the examiner directs the applicant to the above rejection of Claim 1 over Chen et al. and Jeong et al. in view of Watanabe et al., utilized herein to teach the amended limitations of Claim 1.
Prior Art Referral
The prior art made of record and not relied upon is considered pertinent to applicant's disclosure. In addition to the prior art discussed in this action, the applicant is directed to form 892, and particularly the references Xie (CN 112987404), which discloses at least a reflective layer including a transparent film disposed on a side of a reflective film.
