Information Disclosure Statement
The Information Disclosure Statements (IDS) submitted 25 March 2026, 29 May 2026, 22 July 2026, and 18 August 2026 have been considered by the Examiner.

Claim Rejections - 35 USC § 112(d) or fourth paragraph
The following is a quotation of 35 U.S.C. 112(d):
(d) REFERENCE IN DEPENDENT FORMS.—Subject to subsection (e), a claim in dependent form shall contain a reference to a claim previously set forth and then specify a further limitation of the subject matter claimed. A claim in dependent form shall be construed to incorporate by reference all the limitations of the claim to which it refers.

The following is a quotation of pre-AIA 35 U.S.C. 112, fourth paragraph:
Subject to the following paragraph [i.e., the fifth paragraph of pre-AIA 35 U.S.C. 112], a claim in dependent form shall contain a reference to a claim previously set forth and then specify a further limitation of the subject matter claimed. A claim in dependent form shall be construed to incorporate by reference all the limitations of the claim to which it refers.

Claims 10 and 16 are rejected under 35 U.S.C. 112(d) or pre-AIA 35 U.S.C. 112, 4th paragraph, as being of improper dependent form for failing to further limit the subject matter of the claim upon which it depends, or for failing to include all the limitations of the claim upon which it depends.
Claim 10 recites that the total content rate of MgO, CaO, SrO, BaO, and ZnO is “0% or more and 30% or less”. This limitation fails to further limit claim 1, from which it depends since claim 1 recites that the BaO content in terms of mass % is 4% to 25%. Therefore, the lowest the total content rate of MgO, CaO, SrO, BaO, and ZnO can be is 4 mass%.
Claim 16 recites that a ratio of a total content rate of MgO, CaO, SrO, BaO, and ZnO to a total content rate of Li2O, Na2O, and K2O is “0 or more and 3.00 or less”. This limitation fails to further limit claim 1, from which it depends since claim 1 recites that the BaO content in terms of mass % is 4% to 25% and a total content rate of Li2O, Na2O, and K2O in terms of mass % is 5-25%. Therefore, the lowest the ratio of a total content rate of MgO, CaO, SrO, BaO, and ZnO to a total content rate of Li2O, Na2O, and K2O can be is 0.16, so the range would be 0.16-3.00.
Applicant may cancel the claim(s), amend the claim(s) to place the claim(s) in proper dependent form, rewrite the claim(s) in independent form, or present a sufficient showing that the dependent claim(s) complies with the statutory requirements.

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 of this title, 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.

The factual inquiries set forth in Graham v. John Deere Co., 383 U.S. 1, 148 USPQ 459 (1966), that are applied for establishing a background for determining obviousness under 35 U.S.C. 103 are summarized as follows:
1. Determining the scope and contents of the prior art.
2. Ascertaining the differences between the prior art and the claims at issue.
3. Resolving the level of ordinary skill in the pertinent art.
4. Considering objective evidence present in the application indicating obviousness or nonobviousness.

Claims 1-8, 10-14, and 16-25 are rejected under 35 U.S.C. 103 as being unpatentable over Hao et al., Chinese Patent Publication CN 110922050 A.
A machine-generated translation of CN 110922050 A was included with the IDS filed 27 August 2024. In reciting this rejection, the examiner will cite this translation.
Hao et al. teach an optical glass comprising in terms of mole percentages, 15-35% of P2O5, 15-35% of TiO2, 10-30% of Nb2O5, 0-10% of CaO, 10-30% of Na2O, 0-10% of K2O, 0-5% of Li2O, 0-8% of SiO2, 0-5% of Bi2O3, 0-5% of Al2O3, 0-5% of Ta2O5, 0-5% of ZrO2, 0-5% of ZnO, 0-5% of La2O3+Gd2O3+Y2O3+Yb2O3, 0-10% of BaO, 0-10% of SrO, 0-10% of MgO, 0-7% of B2O3, and 0-5% of WO3. See Abstract and the entire specification, specifically, paragraphs [0008]-[0010] and [0029]-[0050]. Hao et al. teach the optical glass has a refractive index of 1.85-1.90. See paragraph [0055]. Hao et al. teach that the optical glass has an Abbe number of 17-23. See paragraph [0055]. Hao et al. teach that the optical glass is used for various optical elements including lenses. See paragraphs [0022], [0077], [0079], [0102] and [0105]. Hao et al. teach that the optical elements are used in many types of optical systems including imaging equipment, microscopes, medical technologies, and digital projectors. See paragraphs [0081] and [0107].
Hao et al. fail to teach any examples or compositional ranges that are sufficiently specific to anticipate the compositional limitations of claims 1-8, 10-14, and 16-25. However, it is believed that the mole percent ranges taught by Hao et al. if converted to mass percentages would have overlapping compositional ranges with instant claims 1-8, 10-14, and 16-25. See paragraphs [0008]-[0010] and [0029]-[0050]. Hao et al. teach Examples 4, 14, 22, 25, 28, and 40, which nearly anticipates the composition and property ranges of claims 1-8, 10-14, and 16-18. See the tables below and the tables at the end of the office action that show the mole percent ranges converted to mass % for Hao et al. Overlapping ranges have been held to establish prima facie obviousness. See MPEP 2144.05. It would have been obvious to one of ordinary skill in the art before the effective filing date to have selected from the overlapping portion of the ranges disclosed by the reference because overlapping ranges have been held to establish prima facie obviousness. See MPEP 2144.05.

One of ordinary skill in the art before the effective filing date would have considered the invention to have been obvious because the compositional ranges taught by Hao et al. overlap the instantly claimed ranges and therefore are considered to establish a prima facie case of obviousness. It would have been obvious to one of ordinary skill in the art to select any portion of the disclosed ranges including the instantly claimed ranges from the ranges disclosed in the prior art reference, particularly in view of the fact that;
“The normal desire of scientists or artisans to improve upon what is already generally known provides the motivation to determine where in a disclosed set of percentage ranges is the optimum combination of percentages”, In re Peterson 65 USPQ2d 1379 (CAFC 2003).

As to claim 19, one of ordinary skill in the art at the time the invention was filled would expect that a glass having overlapping compositional ranges would have an overlapping range for a partial dispersion ratio in the range of 0.61-0.66, as recited in claim 19.
It is well settled that when a claimed composition appears to be substantially the same as a composition disclosed in the prior art, the burden is properly upon the applicant to prove by way of tangible evidence that the prior art composition does not necessarily possess characteristics attributed to the CLAIMED composition.

Fu teaches an optical glass comprising in terms of mole percentages, 20-60% of P2O5, 10-50% of Nb2O5, 5-45% of TiO2, 1-90% of F, 0-40% of ZnO, 0-15% of B2O3, 0-30% of Li2O, 0-30% of Na2O, 0-30% of K2O, 0-30% of MgO, 0-30% of cap, 0-30% of SrO, 0-45% of BaO, 0-10% of Bi2O3, 0-10% of WO3, 0-10% of Y2O3,, 0-10% of La2O3, 0-10% of Gd2O3, 0-10% of Yb2O3, 0-10% of SiO2, 0-10% of GeO2, 0-10% of Al2O3, 0-15% of TeO2, 0-10% of ZrO2, 0-10% of Ta2O5, 0-10% of Ga2O3, 0-10% of SnO2, and 0-3% of Sb2O3. See Abstract and the entire specification, specifically, paragraphs [0010]-[0014] and [0024]-[0050]. Fu teaches the optical glass has a refractive index of 1.70-2.20. See paragraphs [0015] and [0058]. Fu teaches that the optical glass has an Abbe number of 10-35. See paragraphs [0015] and [0058].

Fu teaches that the optical elements are used in many types of optical systems including photographic apparatus and digital cameras. See paragraphs [0002] and [0065].

Fu fails to teach any examples or compositional ranges that are sufficiently specific to anticipate the compositional limitations of claims 1-8, 10-14, 16-23, and 25. However, it is believed that the mole percent ranges taught by Fu if converted to mass percentages would have overlapping compositional ranges with instant claims 1-8, 10-14, 16-23, and 25. See paragraphs [0010]-[0014] and [0024]-[0050]. Fu teaches Examples 12, 14, and 19, which nearly anticipates the composition and property ranges of claims 1-8, 10-14, 16-23, and 25. See Tables 1-7, the tables below and the tables at the end of the office action that show the mole percent ranges converted to mass % for Fu. Overlapping ranges have been held to establish prima facie obviousness. See MPEP 2144.05. It would have been obvious to one of ordinary skill in the art before the effective filing date to have selected from the overlapping portion of the ranges disclosed by the reference because overlapping ranges have been held to establish prima facie obviousness. See MPEP 2144.05.

One of ordinary skill in the art before the effective filing date would have considered the invention to have been obvious because the compositional ranges taught by Fu overlap the instantly claimed ranges and therefore are considered to establish a prima facie case of obviousness. It would have been obvious to one of ordinary skill in the art to select any portion of the disclosed ranges including the instantly claimed ranges from the ranges disclosed in the prior art reference, particularly in view of the fact that;

Fu teaches an optical glass comprising in terms of mole percentages, 20-60% of P2O5, 10-50% of Nb2O5, 5-45% of TiO2, 1-90% of F, 0-40% of ZnO, 0-15% of B2O3, 0-30% of Li2O, 0-30% of Na2O, 0-30% of K2O, 0-30% of MgO, 0-30% of cap, 0-30% of SrO, 0-45% of BaO, 0-10% of Bi2O3, 0-10% of WO3, 0-10% of Y2O3,, 0-10% of La2O3, 0-10% of Gd2O3, 0-10% of Yb2O3, 0-10% of SiO2, 0-10% of GeO2, 0-10% of Al2O3, 0-15% of TeO2, 0-10% of ZrO2, 0-10% of Ta2O5, 0-10% of Ga2O3, 0-10% of SnO2, and 0-3% of Sb2O3. See Abstract and the entire specification, specifically, paragraphs [0010]-[0014] and [0024]-[0050]. Fu teaches the optical glass has a refractive index of 1.70-2.20. See paragraphs [0015] and [0058]. Fu teaches that the optical glass has an Abbe number of 10-35. See paragraphs [0015] and [0058]. Fu teaches that the optical glass is used for various optical elements including lenses. See paragraphs [0002], [0017], [0058], and [0065]. Fu teaches that the optical elements are used in many types of optical systems including photographic apparatus and digital cameras. See paragraphs [0002] and [0065]. Also see the above rejection of claims 1-8, 10-14, 16-23, and 25 over Fu.
Fu fails to teach that the optical glass for the optical devices use cemented lenses.
Fujimoto et al. teach that objective lens systems are formed from cemented lens, including at least a first lens and a second lens. See Abstract and the entire specification, specifically, paragraphs [0003], [0032], and [0045]-[0047]. Fujimoto et al. teach that the lens systems are used in various optical systems including microscope objectives. See paragraph [0003].
It would have been obvious to one of ordinary skill in the art before the effective filing date to have an optical device comprising the optical glass and optical lens of Fu as suggested by Fujimoto et al. because the resultant cemented lens comprising a first lens element and a second lens element wherein at least one of the lens elements comprises the optical glass of Fu, would have the superior glass of Fu with the benefit of the correction of the various aberrations. Fujimoto et al. teach that using a cemented lens serves to favorably correct various aberrations. See paragraph [0046] of Fujimoto et al.
Specifically, the combination of Fu in view of Fujimoto et al. reads on the cemented lens for use in optical systems for objective lens for microscopes as recited in instant claims 24, 26-28, and 30.

Fu fails to teach that the optical glass for the optical devices use cemented lenses and in optical systems for interchangeable camera lens.
Mikami teaches that objective lens systems are formed from cemented lens, including at least a first lens and a second lens. See Abstract and the entire specification, specifically, paragraphs [0223]-[0227]. Mikami teaches that the lens systems are used in various optical systems including interchangeable lens for single lens reflex cameras. See paragraph [0228].
It would have been obvious to one of ordinary skill in the art before the effective filing date to have an optical device comprising the optical glass and optical lens of Fu as suggested by Mikami because the resultant cemented lens comprising a first lens element and a second lens element wherein at least one of the lens elements comprises the optical glass of Fu would have the superior glass Fu with the benefit of the correction of the various aberrations. Mikami teaches that using a cemented lens of a lower dispersion glass concave meniscus lens to mounted to the imaging lens closest to the objective side. See paragraph [0226] of Mikami.
Specifically, the combination of Fu in view of Mikami reads on the cemented lens for use in optical systems for interchangeable camera lens as recited in instant claims 26-7, 29, and 30.
