It seems to me that when a patent covers a product that is sold, the sale implies a license on that patent for that product. The license is sold along with the product. So if the über-toaster is resold, the patent license is sold along with it, regardless of the number of intermediate steps.<p>If that&#x27;s not how the law works, it&#x27;s how it should work. Actually scratch that, the way it should work is to not have patents at all, since they lost their net benefit to society a long time ago (if they ever had it), but that&#x27;s a whole other can of worms.
