1 The lures made from synthetic rubbers are said to be "a significant
2 improvement" over plastisol lures. Specification, page 2, lines 4-5.
3 We are told that the synthetic rubber lures (1) can be colored and
4 shaped, (2) are softer and elastic and (3) not only look lifelike but feel
5 lifelike. Specification, page 2, lines 5-8.
6 The synthetic rubber lures will stretch and will not break like the
7 plastisol lures. Specification, page 2, lines 22-23.
8 Nevertheless, according to applicant the synthetic rubber lures "are
9 extremely tacky." Specification, page 2, line 9.
10 The tackiness causes synthetic rubber lures to stick to one another or
11 the tackle box, which applicant informs us "is unappreciated by the
12 fisherman." Specification, page 2, lines 14-16.
13 Against this background it is said that there was a need to lessen
14 surface tack of lures made from synthetic rubbers. Specification, page 3,
15 lines 1-2.
16 Various patents mentioned in the specification are said to describe
17 reduction of surface tackiness through the incorporation of a stearic acid
18 compound into the synthetic rubber. Specification, page 3, lines 3-9.
19 The use of stearic acid compounds is said to be appropriate in some
20 cases, but in other cases is inappropriate because stearic compounds are said
21 to negatively impact the dyes used to color the lures. Specification, page 3,
22 lines 9-12.
23 Alternatively, a synthetic rubber lure surface may be "detackified"
24 through use of a coating having a silicone oil. Specification, page 3,
25 lines 12-14.
