Appeal No. 1996-1644
Application No. 07/933,147
rejections of claim 1, the broadest claim on appeal,
consistent with 37 CFR § 1.192(c)(7) (1995). Claim 1 is
reproduced below:
1. A process for modifying diamond surface, comprising the
steps of:
oxidizing the diamond surface in an oxygen containing
plasma induced by radio frequency radiation having a power
ranging form [sic, from] 25 to 200 Watts for a period of time
ranging between 10 seconds and 20 minutes, said step of
oxidizing producing an oxidized surface on said diamond
surface; and
attaching to the oxidized surface chemicals having both a
polar surface moiety that bonds with the oxidized surface and
moieties of a desired functionality which do not bond with the
oxidized surface but which are capable of bonding to a
material of interest.
As evidence of obviousness, the examiner relies on the
