Office Action

§102 §103 §112
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 . DETAILED ACTION Abstract The abstract of the disclosure is objected to because it is written in legal terminology which is too similar to claim language. In particular, legal phraseology such as the term “comprising”, “said” and “wherein” which are commonly used to define the limitations and scope pf patent claims, should generally be avoided in U.S. patent abstracts because the purpose of the abstract is not to define the patent claims, but to provide the reader with a clear and concise summary. The abstract should use plain language to describe the invention's technical problem, solution, and principal use. The abstract should be in narrative form and generally limited to a single paragraph on a separate sheet within the range of 50 to 150 words in length. The language should be clear and concise and should not repeat information given in the title. It should avoid using phrases which can be implied, such as, “The disclosure concerns,” etc. Correction is required. See MPEP § 608.01(b). Claim Objections Claim 6 is objected to because of the following informalities: the “that of light” should be “[[that]] a wavelength of light” because it is unclear what the “that” specifically refers to. Claim 16 is objected to because of the following informalities: the “that of the first” should be “[[that]] a resonance distance of the first” because it is unclear what the “that” specifically refers to. Claim 17 is objected to because of the following informalities: the “that of the second” should be “[[that]] a thickness of the second” because it is unclear what the “that” specifically refers to. Claim 18 is objected to because of the following informalities: the “that of the second” in line 6 should be “[[that]] a thickness of the second” because it is unclear what the “that” specifically refers to. 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. Claims 19-20 are rejected under 35 U.S.C. 112(b) as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor regards as the invention. Regarding claim 19, the claim recites the limitation “the first light-emitting device electrode” in line(s) 10. There is insufficient antecedent basis for this limitation in the claim. For the purpose of examination, the examiner construed the limitation as “the first Regarding claim 20, because of the dependency on claim 19, the claim is also rejected for the reasons set forth above with respect to claim 19. 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 Rejections - 35 USC § 103 The following is a quotation of 35 U.S.C. 103 which forms the basis for all obviousness rejections set forth in this Office action: A patent for a claimed invention may not be obtained, notwithstanding that the claimed invention is not identically disclosed as set forth in section 102, if the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to which the claimed invention pertains. Patentability shall not be negated by the manner in which the invention was made. Claims 13-15 are rejected under 35 U.S.C. 103 as being unpatentable over Lim (US 20230209921). Regarding claim 13. Lim discloses The electronic device of claim 1. But Lim does not explicitly disclose wherein the first optical auxiliary electrode has a thickness in a range of about 250 Å to about 2,000 Å. However, the ordinary artisan would have recognized the claimed thickness range used transparent conductive material, e.g. Indium Tin Oxide (ITO) in Organic Photodiodes (OPD) and Organic Light-Emitting Diodes (OLED) to be a result effective variable affecting to make proper balance between electrical conductivity (lower sheet resistance) and optical transmittance. Thus, it would have been obvious that Lim’s electronic device including the OPD and OLED within the claimed range, since optimum or workable ranges of such variables are discoverable through routine experimentation. see MPEP 2144.05 II.B It is further noted that the specification contains no disclosure of either the critical nature of instant claimed thickness or any unexpected results arising thereof. Where patentability is said to be based upon particular chosen values or upon another variable recited in a claim, the applicant must show that the chosen values are critical. In re Woodruff, 919 F.2d 1575, 1578,16 USPQ2d 1934,1936 (Fed Cir.1990). See also In re Boesch, 205 USPQ 215 (CCPA) (discovery of optimum value of result effective variable in known process is ordinarily within skill of art). Regarding claim 14. Lim discloses The electronic device of claim 1. But Lim does not explicitly disclose wherein the photoactive layer has a thickness in a range of about 150 Å to about 1,000 Å. However, the ordinary artisan would have recognized the claimed thickness range of the active (light-absorbing) layer in Organic Photodiodes (OPD) is generally in the claimed range and to be a result effective variable affecting to provide high-efficiency charge extraction. Thus, it would have been obvious that the Lim’s photoactive layer of the electronic device including the OPD within the claimed range, since optimum or workable ranges of such variables are discoverable through routine experimentation. see MPEP 2144.05 II.B It is further noted that the specification contains no disclosure of either the critical nature of instant claimed thickness or any unexpected results arising thereof. Where patentability is said to be based upon particular chosen values or upon another variable recited in a claim, the applicant must show that the chosen values are critical. In re Woodruff, 919 F.2d 1575, 1578,16 USPQ2d 1934,1936 (Fed Cir.1990). See also In re Boesch, 205 USPQ 215 (CCPA) (discovery of optimum value of result effective variable in known process is ordinarily within skill of art). Regarding claim 15. Lim discloses The electronic device of claim 1. But Lim does not explicitly disclose wherein the emission layer has a thickness in a range of about 300 Å to about 700 Å. However, the ordinary artisan would have recognized the claimed thickness range of the active (light-emitting) layer in Organic Light-Emitting Diodes (OLED) is generally in the claimed range and to be a result effective variable affecting to provide enhanced light extraction because organic materials are relatively poor conductors, and thinner layers are necessary to allow electricity to reach the center of the device. Thus, it would have been obvious that the Lim’s emission layer of the electronic device including the OLED within the claimed range, since optimum or workable ranges of such variables are discoverable through routine experimentation. see MPEP 2144.05 II.B It is further noted that the specification contains no disclosure of either the critical nature of instant claimed thickness or any unexpected results arising thereof. Where patentability is said to be based upon particular chosen values or upon another variable recited in a claim, the applicant must show that the chosen values are critical. In re Woodruff, 919 F.2d 1575, 1578,16 USPQ2d 1934,1936 (Fed Cir.1990). See also In re Boesch, 205 USPQ 215 (CCPA) (discovery of optimum value of result effective variable in known process is ordinarily within skill of art). Allowable Subject Matter Claims 8, 10, 16 and 18 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. The following is a statement of reasons for the indication of allowable subject matter: Regarding claim 8. the cited prior art of record does not teach or fairly suggest, along with the other claimed features, “thicknesses of the first optical auxiliary layer and the additional optical auxiliary layer are proportional to wavelengths of light emitted by a subpixel comprising the first optical auxiliary layer and a subpixel comprising the additional optical auxiliary layer, respectively”. Regarding claim 16. the cited prior art of record does not teach or fairly suggest, along with the other claimed features, “the organic photodiode has a resonance distance identical to that of the first subpixel”. Regarding claim 18. the cited prior art of record does not teach or fairly suggest, along with the other claimed features, “thicknesses of the second optical auxiliary layer and the additional optical auxiliary electrode are proportional to wavelengths of light emitted by a subpixel comprising the second optical auxiliary electrode and a subpixel comprising the additional optical auxiliary electrode, respectively”.
