In claim 1 8, the term “ M12Si5N8:Eu ” should be – M¹₂Si₅N₈:Eu – and the term “M1” which appears below this formula should be – M 1 –. In claim 18, the term “ SrqCasAltSiuNv:Eu ” should be – Sr q Ca s Al t Si u N v :Eu –. In claim 18, the term “ Ac[M21-bMn4+bFd] ” should be – A c [M 2 1-b Mn 4+ b F d ] – and the term “M 2 ” which appears below the formula should be – M 2 –. In claim 18, the term “ [M21-bMn4+bFd] ” should be – [M 2 1-b Mn 4+ b F d ] – In claim 18, the term “ A'c'[M2'1-b'Mn4+b'Fd ’ ] ” should be – A' c' [M 2 1-b' Mn 4+ b' F d ’ ] – and the term “M2” which appears below the formula should be – M 2 –. In claim 18, the term “ [M2'1-b'Mn4+b'Fd ’ ] ” should be – [M 2 1-b' Mn 4+ b' F d’ ] – In claim 1 9 , the term “ SrqCasAltSiuNv:Eu ” should be – Sr q Ca s Al t Si u N v :Eu –. In claim 1 9, the term “ Ac[M21-bMn4+bFd] ” should be – A c [M 2 1-b Mn 4+ b F d ] – and the term “M 2 ” which appears below the formula should be – M 2 –. In claim 1 9 , the term “ [M21-bMn4+bFd] ” should be – [M 2 1-b Mn 4+ b F d ] – In claim 1 9 , the term “ A'c'[M2'1-b'Mn4+b'Fd ’ ] ” should be – A' c' [M 2 1-b' Mn 4+ b' F d’ ] – and the term “M2” which appears below the formula should be – M 2 –. In claim 1 9 , the term “ [M2'1-b'Mn4+b'Fd ’ ] ” should be – [M 2 1-b' Mn 4+ b' F d’ ] – In claim 22, the term “ Ln13(Al1-aGaa)5O12:Ce ” should be – Ln 1 3 (Al 1-a Ga a ) 5 O 12 :Ce – and the term “ L n 1” which appears below this formula should be – Ln 1 –. In claim 22, the term “ LawLn2xSi6Ny:Cez ” should be – La w Ln 2 x Si 6 N y :Ce z – and the term “Ln2” (three occurrences) which appears below this formula should be – Ln 2 –. In claim 23, the term “ Ln13(Al1-aGaa)5O12:Ce ” should be – Ln 1 3 (Al 1-a Ga a ) 5 O 12 :Ce – and the term “ Ln 1” which appears below this formula should be – Ln 1 –. In claim 2 3 , the term “ LawLn2xSi6Ny:Cez ” should be – La w Ln 2 x Si 6 N y :Ce z – and the term “Ln2” (three occurrences) which appears below this formula should be – Ln 2 –. A ppropriate 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 appl icant regards as his invention. Claims 14-33 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. In claim 14, in formula (1) it is unclear as to what the variable “dλ” represents in the formula as it has not been defined in the claim. Clarification is requested. In claim 15, in formula (1) it is unclear as to what the variable “dλ” represents in the formula as it has not been defined in the claim. Clarification is requested. In claim 22, the phrase “essentially includes” which appears after formula (2B) renders the claim vague and indefinite as it is unclear as to what is meant by this limitation. Clarification is requested. In claim 23, the phrase “essentially includes” which appears after formula (2B) renders the claim vague and indefinite as it is unclear as to what is meant by this limitation. Clarification is requested. Allowable Subject Matter Claims 14-33 would be allowable if rewritten or amended to overcome the rejection(s) under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA), 2nd paragraph, set forth in this Office action. The following is a statement of reasons for the indication of allowable subject matter: The prior art fails to teach or fairly suggest a light emitting device comprising all of the limitations set forth in the independent claims. References Cited By The Examiner US Patent No. 12,543,417; 12,504,132 B2; 12,163,633; and 12, 163 ,632 teach light emission devices comprising some of the phosphors instantly claimed however they fail to teach or fairly suggest all of the claimed limitations recited in the instant claims. JP 2019-207995 A teaches a similar light emitting device having similar properties however it fails to teach or fairly suggest all of the claimed limitation recited in the instant claims.
