The most feared man in Silicon Valley is no longer this individual (I've learned to say "individual" sometimes when I really mean "SOB"). But a new candidate may now be Nathan Myhrvold.
If you haven't heard of him, catch up here, then watch him here.
Myrhvold says that most companies have policies that inevitably lead to patent infringement. At one point he says emphatically "I know - I was there!" Which is probably as good a time as any to mention that he made his approximately 9 figure net worth with Microsoft.
In the immortal words of Arte Johnson, "verrry interesting".
