Neither do I, but...

The problem with that is that someone needs to be able to *afford* to 
challenge it in court.  Even patents that are blatantly non-original 
on the face of things can be difficult and expensive to challenge. 
Most companies would rather just avoid the legal risks involved in 
making such a challenge, and most individuals can't afford the kind of 
legal team that'd be necessary.

I'll join in encouraging Europeans to do their best to reject these 
styles of patents.  It's a bit too late for the US, but maybe if we 
have concrete examples of the benefits of limiting patents then there 
might be hope for the future.  And if things get too bad here, I'd 
like to have somewhere pleasant to emigrate to. ;)
