example contains SrO, CaO and MgO. See id. ¶¶ 0050-0055 and Tables 1
and 2. The exemplified dielectric compositions were baked for 10 minutes
at 850°C (id. ¶ 0049).
We find Table 1a of Schiller Declaration sets forth four examples of
glass ceramic mass compositions in which glass components have the
following ingredients in mol%:
Glass material 1 2 3 4
La2O3 22.3 20.9 20.1 20.6
B2O3 33.9 31.6 25.7 15.7
TiO2 40.7 38.2 38.9 38.9
BaO 1.0 1.0 1.0 1.0
SrO 1.0 1.0 1.0 1.0
ZrO2 1.0 1.0 1.0 1.0
SiO2 0.0 6.0 12.0 22.0
Schiller Declaration 3. In Tables 1b-d, each of the compositions has the
oxide ceramic component BaNd2Ti0012, and each are baked at 790°C, 820°C,
and 900°C, respectively. The results reported in Tables 1b-d show that only
the glass ceramic mass compositions of Examples 1 and 2 (0.0% and 6.0%
SiO2) baked at 820°C have permittivity, quality, and Tf value properties
falling within the claimed ranges. Declarant Schiller states “[a]s seen from
the tables, increasing the silicon dioxide decreases the” claimed properties,
and concludes silicon dioxide in the range taught by Suzuki would not meet
the claimed properties (Schiller Declaration 3-4).
We find the glass ceramic material compositions 1-4 of the Schiller
Declaration do not fall within the dielectric material compositions described
by Suzuki (see above p. 6). In this respect, the amount of B2O3 in
compositions 1-3 is outside the range disclosed by Suzuki; Al2O3 required in
the compositions described by Suzuki is not present; the amount of TiO2
