Post by JF MezeiIf Vonage just bought turnkey solution from Cisco and didn't develop the 3
technologies in question, then shouldn't Vonage now sue Cisco for having sold it
"damaged" goods and hold Cisco responsible for the cost of the Verizon lawsuit ?
When you buy a product from a reputable vendor, shouldn't you rightly assume
that you are given full rights to use said products and that if there are any
patent infringements, it will be between your vendor and the claimant, and you
won't be involved ?
If Vonage actually developped some of the software in question, then it was the
right target for the lawsuit. But if this is just stuff Vonage bought from
another vendor such as Cisco, I find it strange that a court would have eben
allowed this lawsuit.
Who gets sued for patent infringement depends on the nature of the
claims of a patent (sometimes they are written so that only an end
user or a systems integrator are the actual infringers) and who ticks
off the patent owner. There is no requirement that a patent owner
sue every infringer, but a pattern of not suing infringers that leads
a person to believe that they won't be sued could rise to the level
of a defense called "laches."
Even if you buy something from a reputable vendor, you are never given
full rights to use the product, because that vendor may not have all
the rights. Some may be held by patent owners unknown to the vendor.
What you do get is what the sales contract provides, which is often
that the vendor will pay any damages from your infringement, or will
refund your money, or will make the product noninfringing, or some
combination of those. But you generally have to notify them of any
infringement suit and allow them to handle it.
In the absense of any agreement, here's what the Uniform Commercial
Code provides as a default:
Unless otherwise agreed a seller who is a merchant regularly
dealing in goods of the kind warrants that the goods shall be
delivered free of the rightful claim of any third person by way
of infringement or the like but a buyer who furnishes specifications
to the seller must hold the seller harmless against any such claim
which arises out of compliance with the specifications.
But that's between the vendor and the user. It doesn't keep the patent
owner from suing anybody who infringes the patent, as Vonage did.
