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 .
Election/Restrictions
Applicant’s election without traverse of Species Embodiment 1, with corresponding claims 1-8, 10, and 16-18, in the reply filed on 01/20/2026 is acknowledged. Claims 9, 11-15, and 19-20 are withdrawn from further consideration as being drawn to nonelected Species Embodiments.
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.
The following title is suggested: ORGANIC LIGHT EMITTING TRANSISTOR COMPRISING MICRO-NANO GRATING STRUCTURE AND PREPARATION METHOD THEREOF
Claim Objections
Claims 1-3, 10, and 17 are objected to because of the following informalities:
Regarding claims 1-2 and 17, “a side of the electron transport layer” in line 11 of claim 1, in line 2 of claim 2, and in line 13 of claim 17 should be changed to “the side of the electron transport layer”.
Regarding claim 3, “a side of the base substrate” should be changed to “the side of the base substrate”.
Regarding claim 10, “a side of the first electrode” should be changed to “the side of the first electrode”.
Appropriate correction is required.
Claim Rejections - 35 USC § 112
The following is a quotation of 35 U.S.C. 112(b):
(b) CONCLUSION.—The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the inventor or a joint inventor regards as the invention.
The following is a quotation of 35 U.S.C. 112 (pre-AIA ), second paragraph:
The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the applicant regards as his invention.
Claims 2-8 and 10 are rejected under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), second paragraph, as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor (or for applications subject to pre-AIA 35 U.S.C. 112, the applicant), regards as the invention.
Regarding claim 2, the limitation “an orthographic projection of the fourth micro-nano grating structure on the base substrate is located within an orthographic projection of the second micro-nano grating structure on the base substrate” would render the claim indefinite since the instant application rather describes that the orthographic projection of the fourth micro-nano grating structure 92 formed on the second electrode 9 is located not within the orthographic projection of the second micro-nano grating structure 82 formed on the first electrode 8 (See Fig. 1) [underlying for clarity]. As such, the claimed limitation of claim 2 discussed above is conflicting with the specification of the instant application. Claims 3-8 and 10, which depend from claim 2, are also rejected by virtue of their dependencies.
Claim Rejections - 35 USC § 102
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 16-18 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Chen (US 2020/0035953 A1).
Regarding claim 1, referring to Fig. 6 and related text, Chen teaches an organic light emitting transistor, comprising: a base substrate (1) (paragraph 32); an active layer (2), provided on a side of the base substrate (paragraph 32); a hole transport layer (6), provided on a side of the active layer away from the base substrate (paragraph 38); a light emitting layer (3), provided on a side of the hole transport layer away from the base substrate (paragraphs 36-37); an electron transport layer (5), provided on a side of the light emitting layer away from the base substrate (paragraph 37), wherein at least part of a first micro-nano grating structure (121) is provided on a side of the electron transport layer away from the base substrate (paragraph 37); a first electrode (4), provided on a side of the electron transport layer away from the base substrate (paragraph 32), wherein at least part of a second micro-nano grating structure (111) is provided on a side of the first electrode away from the base substrate (paragraph 31), an orthographic projection of the second micro-nano grating structure on the base substrate is located within an orthographic projection of the first micro-nano grating structure on the base substrate (Fig. 6).
Regarding claim 16, referring to Figs. 5-6 and related text, Chen teaches a method of preparing an organic light emitting transistor, comprising: providing a base substrate (1) (paragraph 32); forming an active layer (2) on a side of the base substrate (paragraphs 32 and 50); forming a hole transport layer (6) on a side of the active layer away from the base substrate (paragraph 38); forming a light emitting layer (3) on a side of the hole transport layer away from the base substrate (paragraphs 36-37 and 51); forming an electron transport layer (5) on a side of the light emitting layer away from the base substrate (paragraph 37); forming at least part of a first micro-nano grating structure (121) on a side of the electron transport layer away from the base substrate (paragraph 37); and forming a first electrode (4) in a region of the electron transport layer provided with the first micro-nano grating structure (paragraph 32), wherein at least part of a second micro-nano grating structure (111) is provided on a side of the first electrode away from the base substrate (paragraph 31), an orthographic projection of the second micro-nano grating structure on the base substrate is located within an orthographic projection of the first micro-nano grating structure on the base substrate (Fig. 6).
Regarding claim 17, Chen teaches a display panel, comprising an organic light emitting transistor, wherein the organic light emitting transistor comprises: a base substrate (1) (paragraph 32); an active layer (2), provided on a side of the base substrate (paragraph 32); a hole transport layer (6), provided on a side of the active layer away from the base substrate (paragraph 38); a light emitting layer (3), provided on a side of the hole transport layer away from the base substrate (paragraphs 36-37); an electron transport layer (5), provided on a side of the light emitting layer away from the base substrate (paragraph 37), wherein at least part of a first micro-nano grating structure (121) is provided on a side of the electron transport layer away from the base substrate (paragraph 37); a first electrode (4), provided on a side of the electron transport layer away from the base substrate (paragraph 32), wherein at least part of a second micro-nano grating structure (111) is provided on a side of the first electrode away from the base substrate (paragraph 31), an orthographic projection of the second micro-nano grating structure on the base substrate is located within an orthographic projection of the first micro-nano grating structure on the base substrate (Fig. 6).
Regarding claim 18, Chen teaches a display apparatus, comprising the display panel of claim 17 (paragraph 58).
