These district court cases have been stayed pending the results of various IPRs.

Taj Reneau, Chairman and CEO said, “As a result of the current state of the patent laws in the U.S., it has been a costly, protracted battle to defend the validity of our patents. We are pleased the Patent and Trademark Office confirmed that Apple failed in its attempt to prove that the claims of the ‘431 and ‘084 Patents are unpatentable. Today’s ruling starts clearing the way for us to proceed with our infringement case against Apple with patents that have been challenged at the PTAB and other patents, which we believe covers millions of units sold by Apple each year.”
