BlackBerry’s patent 8,745,149 is invalid, Patent Trial and Appeal Board says in opinions posted on its electronic docket.
The patent for display of time information for a message in certain circumstances is already covered by other patents, according to the board.
The patent is part of an infringement lawsuit BlackBerry filed against Blu Products mobile phones that use Google’s Android operating system.
Google is awaiting decisions on three other BlackBerry patents it challenged at the U.S. Patent and Trademark Office, according to review board’s docket.
BlackBerry also has sued Snap and Facebook, seeking to increase the amount of patent revenues it receives.
A federal judge invalidated a related BlackBerry time-stamp patent that was asserted against Snap, according to law firm Paul Hastings, which represents Snap in the civil case and Google in the patent office action.
