Appeal 2007-1788
Application 09/766,032
BACKGROUND
“When fishing with a bobber, it can sometimes be difficult to
determine when a fish is nibbling on the angler’s line, especially in waters
that have active waves or when one is fishing for passive or highly sensitive
fish” (Specification 2). According to the Specification, the described bobber
“supplies visual information to the fisherperson through a first-stage
slideable rod that allows the fisherperson to visually determine if a fish is
nibbling the bait by visually observing the displacement of the slideable rod
with respect to a bobber main body but before visual displacement of the
bobber main body can be visually detected. The second-stage permits
anglers to fish in a conventional manner as visual information is provided by
submersion of both the slideable rod and the bobber main body.” (Id. at 2-
3.)
The Specification describes “a two-stage fishing bobber with a main
body carrying a first-stage free sliding retractable rod having a fishing line
engaging member with part of the free sliding retractable rod extending
sufficiently above the main body to enable a fisherperson to keep visual
track of the displacement of the free sliding retractable rod with respect to
the main body. When fishing for large or aggressive fishes, the second stage
of the two-stage bobber is used as a conventional fishing bobber which is
submerged as the fish pulls on the line. When fishing for smaller, passive or
sensitive fishes, the two-stage bobber can be used as a sensitive detection
device as only a slight pull on the line produces a depression of the free
sliding rod with respect to the bobber main body to allow a fisherperson to
visually detect when a fish is nibbling on the bait well before the main body
is visually detectable as being displaceable with respect to the body of water.
