Application No. 08/705,388
rejected claims 1 through 10.
Appellants’ invention pertains to a seal for coaxial
first and second turbine spools rotatable about an axis. A
basic understanding of the invention can be derived from a
reading of exemplary claim 11, a copy of which appears in the
APPENDIX to the brief (Paper No. 16).
As evidence of obviousness, the examiner has applied the
documents listed below:
Schweich 2,020,002 Nov. 5, 1935
Wolff 5,088,889 Feb. 18, 1992
The following rejections are before us for review.
Claims 11 and 12 stand rejected under 35 U.S.C. § 112,
second paragraph, as being indefinite.
Claims 11 and 12 stand rejected under 35 U.S.C. § 103 as
being unpatentable over Schweich in view of Wolff.
