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
This action is in response to applicants’ amendment of 9 December 2025. The amendments to the specification and the replacement figure have overcome the objections to the drawings. In view of applicants’ arguments, the 35 USC 112(a) rejection over claims 3-7 and 18-21 are withdrawn. The 35 USC 112(a) rejection over claims 1, 2, 8-17, 22 and 23 have been modified in view of applicants’ argument.
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, 2, 8-17, 22 and 23 are rejected under 35 U.S.C. 112(a) or 35 U.S.C. 112 (pre-AIA ), first paragraph, as failing to comply with the written description requirement. The claim(s) contains subject matter which was not described in the specification in such a way as to reasonably convey to one skilled in the relevant art that the inventor or a joint inventor, or for applications subject to pre-AIA 35 U.S.C. 112, the inventor(s), at the time the application was filed, had possession of the claimed invention.
Claims 1, 2, 8-1, 22 and 23 teach a light conversion layer comprises a “perovskite matrix comprising a perovskite including an organic ammonium ion which acts as a spacer”, which reads on any large organic ammonium ion containing perovskite. Claim 8 teaches a light conversion layer comprises a “perovskite matrix comprising a perovskite including an organic ammonium ion which acts as a spacer”, which reads on any large organic ammonium ion containing perovskite, as long as the lattice constant of the perovskite has a lattice constant ratio between the perovskite and the quantum dot is in the range of ±3%.
Paragraphs [0089]- [0090] teaches the perovskite of the perovskite matrix in the light conversion layer has a mixed 2D and 3D structure, multi-bandgaps and can be callable of . There is no structure limitations in the rejected claims and thus the perovskite of the claims can have a 2D structure; be capable of absorbing blue light that is not absorbed by the quantum dots of the light conversion layer and be capable of transferring the absorbed blue light in the form of charges to the quantum dots. The claimed perovksites are not limited to those having the structure, bandgaps and possible optical properties taught in the specification. The claims include perovskite that have a 2D structure (which have the formula A2Bn-1MnX3n+1, where A and B are both ammonium ions, M is a metal cation, X is a halogen and n is an integer of 1 or more), those that have a single bandgap, those that have such a larger bandgap that it is not absorbing blue light, and those not capable of converting light to charges. Thus the specification does not support and reasonably convey to one skilled in the relevant art that the inventor or a joint inventor, or for applications subject to pre-AIA 35 U.S.C. 112, the inventors, at the time the application was filed, had possession of all the embodiments of the claimed invention.
Applicants’ arguments have been considered but are not convincing. The claims do not require the argued 2D and 3D structure and argued bandgaps as discussed above. The rejection is maintained.
Allowable Subject Matter
Claims 3-7 and 18-21 are 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.
There is no teaching or suggestion in the art of record of a display device having the structure of claim 1 or 14 wherein the light conversion layers in the device comprise a perovskite matrix and quantum dots, where the perovskite matrix is represented by the formula An-1 B2MnX3n+1, n is an integer of 2 or more, x is a halogen anion, M is metal cation, B is a cation and A is an organic ammonium ion.
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.
