Another day, and yet another audacious-sounding lawsuit in the tech world. This time it's Microsoft (Nasdaq: MSFT) co-founder Paul Allen's company, Interval Licensing, LLC, suing a host of big-name companies: Google (Nasdaq: GOOG), Facebook, eBay (Nasdaq: EBAY), Apple (Nasdaq: AAPL), Yahoo! (Nasdaq: YHOO), AOL, Netflix (Nasdaq: NFLX), Office Depot (NYSE: ODP), OfficeMax, Staples, and YouTube.

The lawsuit claims patent infringement over some basic, ubiquitous, and vital Web functions like reading news in a Web browser and information alerts. In the video below, Fool analyst Rex Moore and Fool Chief Legal Officer Lawrence Greenberg discuss Allen's possible motives, including monetary rewards and credit for inventing these things. The defendants may claim the patents are not valid because the inventions do not meet the patent law's requirement that they be "non-obvious," because people who understood the Internet at the time of their invention would have anticipated them.

The lawsuits may take a long time to work their way through the system if they're litigated and not settled quickly. Most of these companies have very deep pockets and the ability to absorb the costs involved. Though it seems unlikely these companies would be seriously hurt by the final outcome in a meaningful way, it's unlikely that they are happy to have been sued.
