IIRC, big companies used to claim they were gathering these patents to _prevent_ this situation from happening, using a similar logic to that of hoarding nuclear weapons to mutually assured destruction.

But it appears that something in the balance has changed, and I'm not really sure what. Are the lawyers just doing a bad job of agreeing on the licensing fees (i.e. penalty for having less cross-targeted bombs for a given opponent)? It's hard to know what to make of it all, putting myself in the shoes of an exec at one of these large companies. At least when I was at MSFT, we used to worry about this thing called "bad press" around lawsuits of this kind...
