Office Action

§102
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 . Specification The title of the invention is not descriptive. A new title is required that is clearly indicative of the invention to which the claims are directed. Claim Rejections - 35 USC § 102 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. 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 – (a)(2) the claimed invention was described in a patent issued under section 151, or in an application for patent published or deemed published under section 122(b), in which the patent or application, as the case may be, names another inventor and was effectively filed before the effective filing date of the claimed invention. Claims 1-5 are rejected under 35 U.S.C. 102(a)(2) as being anticipated by Kim (20190198796). Regarding clam 1, Kim teaches a method of fabricating an electroluminescent device, the method comprising: providing a substrate with a layer of anode material (par. 57-60); forming a hole transport layer on the layer of anode material (par. 61 and 66); forming a layer of quantum dots on the hole transport layer (par. 67-88); forming a hybrid transport layer comprising an organic layer and inorganic nanostructures on the layer of quantum dots (par. 89-129); and forming a cathode on the hybrid transport layer (par. 60). Regarding clam 2, Kim teaches a method of claim 1, wherein the forming the hybrid transport layer comprises preparing a solution with the inorganic nanostructures and an organic material of the organic layer in an organic solvent (par. 89-129). Regarding clam 3, Kim teaches a method of claim 1, wherein the forming the hybrid transport layer comprises: preparing a first solution with the inorganic nanostructures in a first solvent; and preparing a second solution with an organic material of the organic layer in a second solvent that is different form the first solvent (par. 89-129). Regarding clam 4, Kim teaches a method of claim 1, wherein the forming the hybrid transport layer comprises preparing a solution with an organic material comprising two or more phosphonic oxide functional groups (P═O) (par. 89-129). Regarding clam 5, Kim teaches a method of claim 1, wherein the forming the hybrid transport layer comprises: preparing a solution with (1,3,5-Triazine-2,4,6-triyl)tris(benzene-3,1-diyl)tris(diphenylphosphine oxide), 2,4,6-Tris[3-(diphenylphosphinyl)phenyl]-1,3,5-triazine, which has three phosphonic oxide functional groups (P═O) (par. 89-129). Allowable Subject Matter Claim 6 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. Conclusion Any inquiry concerning this communication or earlier communications from the examiner should be directed to CALEB E HENRY whose telephone number is (571)270-5370.
