Well, if you are not actively copying it to a U.S. website you should be less exposed. However, anyone in the USA who downloads a copy of your software can theoretically be sued.
Keep in mind, however, that the recipients of your software do not have the right to redistribute the software if a patent holder refuses to grant a royalty-free patent license for the software. See section 7 of the GPL.
Even your US team members may be in trouble, as "making a patented invention" is forbidden without permission. However, the big question for them is whether you're worth the effort.
They are aiming at small companies - I checked the fifty companies that they have sued - none of them uses our program. But it also seems that they do not sue the program makers - only the users. Hrmpf.
A nasty trick, since the users will complain to the manufacturer and force him to take out a license.
And I really really would like to stress that you should never say "our program exactly infringes those patents". If you get sued, and the opposing party finds this message in the public archive or something, you've basically lost the trial.
I didn't say that. Read those patents. They cover every program that uses text and images to sell a product. How can any eCommerce program not meet those specs? :-(
I haven't reviewed the patents, but even if the claims at first sight appear to be very broad, there can be many reasons why you still wouldn't infringe. For example, a term can be given a limited definition in the text. Or maybe the applicant said during prosecution that it is essential that feature X must be done so and so. In that case, even if feature X is given in the claim in a very broad way, you only infringe if you do it exactly so and so. Claim analysis is very difficult.
However, I was simply trying to say that you should never put in writing "my product infringes on this patent", even if to you this is the only possible conclusion. By your own admission you then know that you need to obtain a license. Since you didn't obtain a license, you are willfully infringing on somebody else's patent, and that may cost you a lot of money. I always tell people in my company to say "this patent looks very relevant to our product" and to leave the detailed analysis of infringement to the patent attorneys.
