A small Virginia company in a patent fight with eBay Inc. asked a federal judge on June 12 to stop the online auction powerhouse from using its “Buy It Now” feature allowing shoppers to buy items at a fixed price.

A federal jury found in 2003 that eBay had infringed Great Falls-based MercExchange LLC’s patent. But last year, the U.S. Supreme Court handed a victory to patent-reform advocates when it ruled that MercExchange was not automatically entitled to a court order blocking the offending service.
