temperature of the transfer layer they are either removed by
sublimation or converted to a form “which does not interfere
with the transfer of the design to the textile.” See the Reed
abstract. Reed does disclose that particulate polyesters may
be used as non-blocking particles in the transfer sheet, but
further specifies that such polyesters are low molecular
weight linear polyesters which, when melted, form a phase
separate from the polymeric transfer layer. See Reed at
column 5, lines 7-11. Although appellant describes the use of
a polyester as the source of his “adhesive-abrasive” particles
as a preferred embodiment of his invention, appellant
identifies the particulate polyester for the claimed invention
as ground polyester which is “commonly used in the textile
industry to adhere sections of fabric together”. See the
specification at page 8, lines 22-24. Moreover, appellant
defines his “abrasive-adhesive” particles as forming “an
extremely strong mechanical adhesive bond when melted into the
fibers of a section of fabric” (specification at page 8, lines
27-29), not a separate phase which “does not interfere” with
the transfer of Reed’s design to the fabric. Accordingly,
