Paul Allen, co-founder of Microsoft, is going on a suing spree, suing 11 internet search and e-commerce companies.

Apple, Google, and 9 other internet companies are named in a lawsuit. Paul Allen says that all of the companies are using a technology that his now-obsolete company, Interval Research Corp., developed over ten years ago.

Allen claims that his defunct company developed the “online recommendations” technology, which all of these 11 companies that are involved in the suit, are using on their websites. The online recommendation feature includes recommend products similar to the one which the customer is looking at, as well as providing related search terms on search engines.

The companies which were named in the suit are Apple, Google, AOL, eBay, Facebook, Netflix, Office Depot, Office Max, Staples, Yahoo and YouTube. What’s interesting about this is that Paul Allen is not suing any companies that are located in the Seattle (Allen’s hometown) area, such as Amazon and Microsoft.
