Since the European patent that Channel Intelligence tries to sue us with doesn't seem to be granted yet. I'm now looking for prior art to stop the patent from being awarded. This could make this lawsuit go simply go away for everyone they targeted in Europe.

Below is a list of what I already found with the help of friends. If you have other suggestions, please add them as comments.

Also, I'd appreciate it if people could help me to read over the patent and validate the applicability of this prior art. I might have missed something.

• 2001 : The Things I Want (http://thethingsiwant.com) - create universal online wishlists and gift registries
  
  
• 2000 : ShopSmart (web archive) - allowed you to create lists of items, to compare the prices and to prioritize them. A friend of mine worked on this application and there are even articles published about it in the Sunday Times and the Daily Post. Still looking for copies of those.
  
  
• 1999 : Kelkoo (http://kelkoo.com) - seems to do exactly what is described in the patent, I contacted them to see if they can help to protest against the patent application.
  
  
• 1997 : No Amiga To Waste (http://thunderstorms.org/NATW) - this is an application that I created where lists of ideas can be created and commented on over the internet. While not 100% inside e-commerce realm (Bla-bla List isn't either btw), this can be seen as prior art imho.
  
  
• 1996 : Peapod (http://peapod.com) - allows you to create online grocery lists.
  
  

The official complaint from Channel Intelligence states the US patent number but it only vaguely mentions that they 'own the foreign equivalents'. I thus decided to search for them, and I found this: http://register1.epoline.org/espacenet/regviewer.

It turns out that the equivalent European patent is still under examination. I've contacted the Belgian patent office to see what the local status is and they're getting back to me shortly. With the abundance of prior art, it might actually be easy to stop the patent from being granted in Europe now. Apparently it's much more effective to intervene during the examination process than it is to contest the patent once it's granted.
