Our Company has a product with 2 U.S. and 1 Canadian patent. Where do
I go to sell my patents and how do I get all the correct legal papers
to do so?

A patent is like any other real property -- it can be rented, leased
or sold -- with any terms that are OK with both parties.  The only
paper work you need is a contract spelling out the terms of the deal.

Where do you go to sell the patents?  You either go to the people who
want to make the item or go to the people who do not want anyone to
make the item (competitors).  The patents give the owner the right to
"stop" people from making the item.

Hi,

If you already have a patent and you want to sell it, I would suggest
that you visit websites that may help such as http://www.yet2.com,
http://www.uventures.com/, http://www.buypatents.com/, ...
There is also a new website which provides this service for free at
http://www.freepatentauction.com/.
I would suggest that you list your patent on one or more of these
websites and see what happens...
If you are able to identify a company which is ready to buy your
patent, then the paperwork will be a peace of cake. You just hire an
attorney who may draft you a standard argeement in a couple of hours
if you have all the terms negotiated.
Good luck in your business !
