Walt Mossberg – Apps Raise the iPad’s Aptitude for Real Work
Technology companies used to condemn what critics call “patent trolls,” ventures that profit from innovations they themselves often had no hand in creating. Now, some of those companies are taking pages from the trolls’ playbooks. To bring in extra cash, some big names in the tech industry are spinning off their patents into separate entities, with the aim of pressuring other companies to license the technology and suing when they can’t reach deals.
Along with original content and posts from across the Dow Jones network, this section of AllThingsD includes Must-Reads From Other Web Sites — pieces we’ve read, discussions we’ve followed, stuff we like. Six posts from external sites are included here each weekday, but we only run the headlines. We link to the original sites for the rest. These posts are explicitly labeled, so it’s clear that the content comes from other Web sites, and for clarity’s sake, all outside posts run against a pink background.
We also solicit original full-length posts and accept some unsolicited submissions.
