I'm confused about this distinction between Paul & Nathan? >Mr. Allen's lawsuit comes amid high-profile successes of firms such as NTP Inc., which enforce patents without making products and have been called "patent trolls" by critics. What is this distinction supposed to serve? I see "Mr. Allen's lawsuit" and I also see that he purposefully kept Amazon & Microsoft out, which means he must be involved somehow personally. > Another Microsoft veteran, former chief technology officer Nathan Myhrvold, has amassed thousands of patents and secured hundreds of millions of dollars in patent-licensing deals from telecommunications companies and others. Mr. Myhrvold's Seattle-based firm Intellectual Ventures patents some of its inventions but also acquires patents to license. Ok... yes Nathan is doing that separately. This is about Paul.
