Time Bandit Posted June 15, 2018 Report Share Posted June 15, 2018 I wanted to check something with you experts here....I was told recently that there is a patent held on the delta blades used on buzzbaits. I'm referencing the blades where the wire passes through the middle of the blade itself going from the tab on the front of the blade to the one on the back. This sounded wildly inaccurate to me, but I wanted to check it with you guys first. Anybody heard this or know anything about it? Quote Link to comment Share on other sites More sharing options...
JLS Posted June 17, 2018 Report Share Posted June 17, 2018 I'm sure there would be a patent on those blades, but I really have no need to know for sure. The patent would make it illegal for you to manufacture those blades without being licensed to do so, whether it be for personal use or resale. When you purchase the blades from a manufacturer (in this case, Worth), you are allowed to use those blades. Quote Link to comment Share on other sites More sharing options...
Anglinarcher Posted June 18, 2018 Report Share Posted June 18, 2018 Patents only last so long and the Delta blades have been out for at least 40 years that I know of. Knock offs of that blade and lures made with that blade are everywhere. Was there one, probably. Is there a current one, I doubt it very strongly.

EironBreaker Posted June 18, 2018 Report Share Posted June 18, 2018 Anglinarcher, I don't know if there are knockoffs of that style. And the patent number is stamped on all of the delta blades. The off-set style which the wire stays on one side doesn't have a patent that I know of. The War Eagle buzzbait has the off-set style blade. Battlefield Wire used to make the delta blade and they were about 5 miles from where I formerly lived. Was in their shop several times and they said they had stamped enough blades over the years to cover the bottom of the great lakes, lol. I believe Worth bought their tooling and patent.

Anglinarcher Posted June 18, 2018 Report Share Posted June 18, 2018 IF you have the patent number, you can search it out and see if it is sill effective. Lots of patents still get stamped that are no longer valid. Just like Patent Applied is stamped to discourage people from making copies, even if the item is not patentable. 1 Quote Link to comment Share on other sites More sharing options...
JBarlow Posted June 20, 2018 Report Share Posted June 20, 2018 To the best of my knowledge the patent on these blades expired a number of years ago. The blades I have in stock no longer carry a patent number. 1 Quote Link to comment Share on other sites More sharing options...
