(RD 3-5)). Based on his calculations, Winter found that
syndio-isoblock polypropylenes made in accordance with the
examples of Dolle Application 08/147,006 have molecular chains
in which syndiotactic and isotactic sequences are present and
the average sequence length of each of the syndiotactic and
isotactic sequences is 3 to 50 monomer units, whereas the
average sequence length of each of the syndiotactic and
isotactic sequences of the syndiotactic polypropylenes made in
accordance with the examples in Ewen et al., U.S. Patent
4,892,851, and the isotactic stereoblock polypropylenes made
in accordance with examples in Ewen, U.S. Patent 4,522,982, is
not 3 to 50 monomer units (Declaration of Andreas Winter dated
July 10, 1995, pp. 3-4
(RD 3-5)).6
In light of the evidence, we see no error in the APJ’s
conclusion that, read in light of Dolle’s specification, the
phrase “sequence length” in the phrase “syndio-isoblock
polymer[(s)] having molecular chains in which syndiotactic and
isotactic sequences are present and the sequence length is 3
6 We note that the isotactic stereoblock polypropylenes
claimed in Ewen, U.S. 4,522,982, are defined in terms of “average
block length” and “the average block length contains from about 3
to 50 repeating units” (Ewen, U.S. Patent 4,522,982, col. 12,
Claim 2).
