Appeal No. 95-3834
Application No. 07/947,569
DECISION ON APPEAL
This is an appeal under 35 U.S.C. § 134 from the
rejection of claims 1-12, all of the claims pending in the
application. Claims 1 and 9 are representative of the subject
matter on appeal and read as follows:
1. A dry engine oil additive comprising the mixture of a
granular metal alloy material and granular polytetrafluoro-
ethylene (PTFE), wherein the granules are micron to sub-micron
in diameter; the granulated metal alloy material for being
peened and burnished to bearing surfaces in an engine and the
PTFE granules for being embedded within the matrix formed
thereby.
9. The method of lubricating an engine and repairing
surface abrasions on bearing surfaces comprising adding a
supply of a mixture of a granulated metal alloy metal and
polytetra-fluoroethylene (PTFE) granules having micron to
submicron sizes to an oil supply within an engine, running the
engine for a time sufficient to cause the granules of the
granulated metal alloy material to be peened and burnished to
bearing surfaces within the engine, thereby embedding PTFE
granules within the matrix of granulated metal alloy material
formed by the peening and burnishing.
The references relied upon by the examiner are:
Cairns 3,994,814 Nov. 30, 1976
McCready 4,888,122 Dec. 19, 1989
The sole issue in this appeal is whether claims 1-12 were
properly rejected under 35 U.S.C. § 103 as being unpatentable
over the combination of McCready and Cairns.
