Uniloc 2017, a non-practicing entity affiliated with the original Uniloc, sued Paychex, Akamai and athenahealth, accusing each of infringing a pair of patents relating to the management and distribution of application programs to target stations on a network. The patents originally belonged to IBM, and have an odd chain of title through the PTO 2019s assignment page 2013 it appears that Uniloc assigned a security interest in the patents to Fortress Credit Co. in 2014 without having first obtained title from IBM 2013 that assignment (to Uniloc Luxembourg S.A.) was executed in 2016. The patents each claim priority to a December 1998 filing, so both have expired. The cases are all before Judge Stearns.
