Not all companies are like this. I work for a company that believes enforcement of patents stifles innovation. And looking for the next innovation and gaining a first mover advantage is much more important than spending time and resources protecting past ones.Plus the end user is much better off in this market. We will patent to protect ourselves from other companies, but not enforce it on others.

However this needs an idealistic leader and wont work large scale across markets so while it annoys me when I see these spiderwebs of who is suing who, I really put the blame at the fault of the patent system. I don't know what the answer is but it seems something is seriously broken.
