A Federal Circuit judge has rejected Uniloc's challenge of a previous FaceTime VoIP patent ruling that was chiefly in Apple's favor.

Among the many patent disputes from Uniloc, one concerning FaceTime and its use of VoIP technology was previously overturned by the Patent Trial and Appeal Board (PTAB). That ruling has now been confirmed at appeal.

According to Reuters, Uniloc had attempted to revive parts of its patent dispute and that attempt has now been denied by Circuit Judge William Bryson. However, Bryson also rejected Apple's separate request to cancel other parts of the patent.

Apple had successfully argued overall that Uniloc's patents included elements that were invalid because of prior patents. Uniloc's position was that the ruling board had misconstrued aspects of the invention.
