DECISION ON APPEAL
This is a decision on an appeal under 35 U.S.C. § 134 from the final rejection of claims 1
through 11, all of the claims pending in the application. The claims on appeal are directed to a
method of making a medicinal inhalation device and a component for the device using a thermal
chemical vapor deposition (CVD) process. Claim 2 is illustrative and reads as follows:
2. A method of making a component for a medicinal inhalation device comprising a step of
forming a fluorocarbon (CF2)n-type polymer thin film on a surface of the component, said
forming step comprising the sub-steps of:
a) exposing a monomer gas to a source of heat having a temperature sufficient to
pyrolyze the monomer gas, the monomer gas selected to produce upon pyrolysis a source
of reactive species that includes polymerizable CF2 species and that selectively promotes
CF2 polymerization, the reactive species source being in the vicinity of the surface on
which the fluorocarbon polymer film is to be formed; and
b) maintaining the surface substantially at a temperature lower than that of the heat
source to induce deposition and polymerization of the CF2 species on the surface.
