“comprising” and “containing” open the claims to include glass ceramic
masses that include any amount of any additional ingredients in the oxide
ceramic component and the glass material component or otherwise, such as
silicon oxide SiO2 and aluminum oxide Al2O3, not otherwise provided for,
limited only by the specified composition properties. See, e.g., Exxon Chem.
Pats., Inc. v. Lubrizol Corp., 64 F.3d 1553, 1555, 35 USPQ2d 1801, 1802
(Fed. Cir. 1995) (“The claimed composition is defined as comprising -
meaning containing at least - five specific ingredients.”); In re Baxter, 656
F.2d 679, 686-87, 210 USPQ 795, 802-03 (CCPA 1981) (“As long as one of
the monomers in the reaction is propylene, any other monomer may be
present, because the term ‘comprises’ permits the inclusion of other steps,
elements, or materials.”).
We find Suzuki describes a dielectric composition containing a glass
component containing 10-40 mol% lanthanide series oxide Ln2O3, 20-50
mol% SiO2, 5-20 mol% boric oxide B2O3, 7-20 mol% aluminum oxide
Al2O3, and 10-40 mol% of at least one of zirconium oxide ZrO2, titanium
oxide TiO2, and niobium oxide Nb2O5, and a dielectric material component
having a dielectric constant greater than the glass and containing any oxide
containing titanium, such as TiO2 (Suzuki, e.g., 1-2 and ¶¶ 0006 and
0014-0019). Suzuki discloses that if SiO2 content is less than 20 mol%, “the
glass easily deteriorates, and vitrification becomes difficult” (id.
