Interference No. 103,446
The subject matter contested in this interference is
directed to a cured, filled polyurethane/polyurea polymer
composition having dispersed therein a particular mica filler.
The surface of the filled polymer composition, when painted
and compared with the painted surface of similarly painted
steel, exhibits a distinctness of image (DOI) within about 10
(ten) DOI units of the DOI of said similarly painted steel.
The cured and filled polymers are useful in the manufacture of
automobile parts such as fenders and doors. Automobile parts
manufactured from said polymers are lighter than comparable
metal parts which enable a reduction in the overall weight of
the finished automobile which yields improved fuel economy.
The specific interfering subject matter contested by
the parties is defined by the sole count in this interference,
Count 1, which is set forth as follows:
A filled polymer composition
comprising a polyurethane and/or
polyurea matrix having dispersed
therein a mica filler having a
thickness of less than about 1.5
micrometers and an aspect ratio of
greater than about 40, the surface of
the composition exhibiting a
distinctness of image when painted
that is within about 10 DOI units of
the distinctness of image of similarly
painted steel.
