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 .
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)(1) the claimed invention was patented, described in a printed publication, or in public use, on sale, or otherwise available to the public before the effective filing date of the claimed invention.
(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, and 6 – 9 are rejected under 35 U.S.C. 102(a)(1)/(a)(2) as being anticipated by US Patent Application Publication No. 2019/0221623 to Kamiyama.
Regarding claim 1, Kamiyama teaches a display device comprising:
an anode (13, ¶[0071]) ;
a hole injection layer (15);
a first light-emitting layer (17R) that emits light of a first color; and
a cathode (21),
wherein the hole injection layer contains a mixture (PEDOT/PSS) in which polystyrene sulfonic acid (PSS) is mixed with polyethylene dioxythiophene (PEDOT) (¶ [0080]), and
a first polymer (16, ¶ [0082]) adjacent to the PEDOT/PSS.
Regarding claim 6, Kamiyama teaches a display device, further comprising: a second light-emitting layer (17G) that emits light of a second color different from the first color.
Regarding claim 7, Kamiyama teaches a display device, wherein the hole injection layer is a single layer.
Regarding claim 8, Kamiyama teaches a display device (Fig. 6D), wherein the anode includes a first pixel electrode (13R) and a second pixel electrode (13G), and the hole injection layer includes a first portion (15) overlapping the first pixel electrode and a second portion (15) overlapping the second pixel electrode, the first portion being separated from the second portion. See Fig. 6D.
Regarding claim 9, Kamiyama teaches a display device, wherein the hole injection layer includes a lower layer containing the PEDOT/PSS, and an upper layer containing the first polymer (16) and covering the lower layer.
Allowable Subject Matter
Claims 2 – 5 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.
Conclusion
The prior art made of record and not relied upon is considered pertinent to applicant's disclosure. US Patent Application Publication No. 20230369545 to Ohshima et al. teach a display device including an anode, a cathode and hole transport layer comprising PEDOT-PSS. Ohshima et al. do not specifically teach that the hole transport layer is a hole injection layer, nor do Ohshima et al. teach a polymer adjacent to the PEDOT-PSS.
