Any wording of sweet an/or beaver associated w/ any other crayfish type of commercial soft-bait would probably receive a cease and desist letter I.M.O.
I am not a specialized lawyer but do have a personal experience w/ my own trademark dispute 21 years ago.My lawyer said we could win but wanted 20k to defend it in Washington. But what if i loose?
The trademark office searched the name and drawings when we applied, said it was clean , not used and an exclusive trade mark would be issued if no one objected. The company that objected was a subsidiary of Johnson Wax. and filed the objection on the last day possible before the trademark was issued.My name and drawing logos were entirely different but the name began w/the same last letter of the alphabet. It cost me an additional $3500.00 w/the lawyers and I left disgusted and changed the name. i can only imagine what a patent infringement suit can cost in legal fees. The entire education & deal cost me $7500.00 plus shirts,hats ,jackets and pre-printed lure cards. that's exactly why I use my own name for the company now. All this legal stuff comes down to who has the fatter wallet and is willing to take a big financial chance and liability in court w/ a patent/trademark dispute.
That is many.many free baits
