Intellectual Ventures, the patent acquisition company founded by former Microsoft Chief Technology Officer Nathan Myhrvold, laid off some of its staff Wednesday.

The Bellevue company declined to say how many people were laid off or to talk specifically about what led to the layoffs. Intellectual Ventures said it had eliminated about 5 percent of its global workforce.

The company, which has been called a “patent troll” by some, said in a statement: “Intellectual Ventures has always had a bold vision — to establish an active market for invention where inventors realize the value of their ideas.
