Hello,

I am interesting in the production of a dovetail jig at a very good
price.
There is a lot of maker of dovetail jig: Sears Craftsman, Porter
Cable, Keller, Stots, etc... And there is also several patents
regrading dovetail jigs.
I can't imagine that some manufacturers pay someone just to have the
right to produce a dovetail jig. Despite Their models are quite
similar.

What do you know about that?
Is it possible to sell a Carftsman/Porte Cable look alike?

If there is an applicable patent that has not expired (remember, patents
are
only good for a limited time, IIRC 37 years but do check with the patent
office) then your choices are to license the patent or design around it.
Designing around it is tricky and is as much lawyer-work as engineer-work.

And yes, manufacturers do pay license fees to other manufacturers if they
cannot successfully design around the patent. The license fee is then
built into the selling price.

Any help needed.
Thank you very much.

And do you have the money to fight a patent suit?
