in view of the teaching of Miya, U.S. 4,931,417 (attached
hereto as Appendix B), issued June 5, 1990, from Application
07/266,065, filed November 2, 1988 (Paper No. 52, p. 12, l. 7-
8). After holding that “Miya . . . is prior art under 35
U.S.C. § 102(e)” (Paper No. 52, p. 9, last para.), the APJ
found, inter alia (Paper No. 52, pp. 7-9):
44. Miya expressly describes a number of metallocene
compounds . . . some of which fall within the
generic
formula set out in Ewen 034's claims 1-3 and 5-8 and
lack bilateral symmetry. . . .
. . . . .
46. Miya discloses the use of an ionizing agent along
with
the metallocene compound, including
methylaluminoxane,
in carrying out polymerizations. . . .
47. Miya teaches that the compounds are useful as a
catalyst for “stereoregular-olefin polymerization.”
Miya, col. 1, lines 10-12.
48. Miya’s Examples 7, 9, 15, 17, and 21 describe
polymerizations using metallocene compounds which
lack
bilateral symmetry and are covered by the general
formula of claims 1-3 and 5-7 of Ewen 034.
49. Miya’s examples 7, 9, 15, 17 and 21 demonstrate
polymerizations which result in the formation of
isotactic polymers.
50. Miya does not describe the formation of
hemiisotactic polymers.
51. Because of the lack of description of hemiisotactic
