Office Action

§102 §112
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 § 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 appl icant regards as his invention. Claim s 8, 9, 11-13, 15, and 16 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 claims 8, 9, 11-13, and 15, t he term "surface-etching material" is vague and unclear and leave s in doubt as to the meaning of the technical features to which it refers . Further clarification is needed . Regarding c laim s 9 and 16, the term "Binding energy" is indefinite. The term is not a generally accepted term as such but is always placed in a context. In the application such a definition is missing. Further clarification is needed. 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. Claim(s) 1-20 is/are rejected under 35 U.S.C. 102 (a)(1) as being anticipated by Kim et al. (EP 3819354) (hereafter “Kim”) . Regarding claims 1-20, Kim teaches a core shell quantum dot (and the method of making the quantum dot) comprising an InP core with a ratio of 1:0.8 of In to P and a shell of ZnSe and ZnS (paragraphs [0269]-[0280]). Kim teaches that the where the shell is being added the core is exposed of AlCl 3 (which is a surface etching material taught by the applicant and forms on the second semiconductor agent with P on the sure of the core) ( paragraphs [0269]-[0280] ). The second semiconductor would be composed of Al-P which as a greater binding that In-P. Kim teaches that the quantum dots can be made to emit blue light (wavelength between 440nm and 470 nm) (paragraph [0076]) . Kim teaches that the quantum dots can be used in electronic apparatus as either the emitting layer in an light emitting device or a color conversion member in the path of light emitted from a light source (paragraph [0198]-[0205]). Conclusion The prior art made of record and not relied upon is considered pertinent to applicant's disclosure. Chow et al. (US 2020/0325396) teaches InP/ZnSe/ZnS core shell quantum dots where the core can be etched.
