The appellants' invention relates to a surface treatment for a piston ring for use
in internal combustion engines (specification, p. 1). A copy of the claims under appeal
is set forth in the appendix to the appellants' brief.

Claims 3, 6, 8 and 10 stand rejected under 35 U.S.C. § 112, first paragraph, as
containing subject matter which was not described in the specification in such a way as
to reasonably convey to one skilled in the relevant art that the appellants, at the time
the application was filed, had possession of the claimed invention.
Claims 3, 6, 8 and 10 stand rejected under 35 U.S.C. § 112, second paragraph,
as being indefinite for failing to particularly point out and distinctly claim the subject
matter which the appellants regard as the invention.
