Case Closed: Jun 14, 2013
Court: Rodney Gilstrap
Judge: Texas Eastern District Court
Case Summary:
A patent infringement suit was filed
against Sony by Tierra Intelectual Borinquen
(TIB) claiming that their patents covering authentication system for unlocking
a mobile device were infringed. The patents involved in the suit were:
- US7350078 entitled User selection of computer login was issued on Mar 25, 2008
- US7725725 entitled User-selectable signatures was issued on May 25, 2010
The patents expire[i]
by Mar 04, 2022 and are currently assigned[ii]
to TIB (source: MaxVal’s Assignment Database). According to the complaint, the
‘078 and ‘725 patents cover a computer implemented method for creating a
signature for subsequent authentication, including authentication based on user
input signals from user selectable input devices. The patents protect a system
allowing users to choose between a password, face recognition and some other
login method, to unlock a mobile phone. Plaintiff alleged that defendants
manufacture mobile devices including Xperia™ that infringe the method claimed
in the patents. Plaintiff sought permanent injunction and money damages.
It appears that the parties have
settled the case amongst themselves and TIB filed for voluntary dismissal.
Pursuant to the dismissal filed, Judge ordered all claims against Sony and
counterclaims against TIB to be dismissed with prejudice, with each party to
bear their costs and expenses incurred.
