A U.S. trade panel that deals with patent infringement cases took a step on Monday that could rein in companies, often known as patent trolls, accused of embarking on frivolous litigation.

The commission said it created a pilot program in which its six administrative judges will in some cases determine within 100 days if companies that sue for infringement have adequate U.S. production, research or licensing to use the court.
