1 characterization of the supposed "non-permanency" of prior art lures: "as
2 the [prior art] lure is used repeatedly in water, the oil is washed from the
3 surface of the lure and it reverts to its tacky nature." Specification, page 3,
4 lines 14-16. The coating of the prior art lures, as well as applicant's lures, at
5 some point revert to a tacky state. "Permanent" does not tell one skilled in
6 the art in any practical sense how the return to tackiness of applicant's lures
7 is to be distinguished from the return to tackiness of the prior art lure.

10 A review of the prior art discussed in the specification reveals that a
11 point of novelty of applicant's claimed invention is the use of a detackifier
12 which (1) has a particulate size of 2 nanometers to 10 microns (claim 1
13 and 17), (2) has a surface area of less than 1,000 square meters per gram
14 (claims 17 and 19) and/or (3) is combined with a coating oil in a particular
15 ratio, viz., 8000:25 ± 20 (claim 19).
16 Styrene block copolymers have been used to make lures. The
17 STEREON 840 copolymer described by Hastings (col. 2, lines 43-46) is a
18 styrene butadiene block copolymer. See, e.g., U.S. Patent 4,582,876 issued
19 to Weemes on 15 April 1986 and filed (10 September 1984) shortly after
20 Hastings (25 July 1984). At col. 6, lines 39-42 Weemes says: "Stereon 840
21 is a graded diblock copolymer of about 57% by weight butadiene and 43%
22 by weight styrene and is sold by Firestone Synthetic Rubber & Latex Co."
23 Thus, Hastings describes, consistent with applicant's description of the prior
24 art, the use of styrene block copolymers to make lures.
25 Likewise, described by Hastings is the use of oil in combination with
26 the styrene block copolymers and like applicant generally more oil is present
27 than styrene block copolymer.
