Essentially, the same filing against lots of big companies, including
Microsoft, Yahoo, and Facebook. And Apple.
Cause of Action: Filed for the alleged infringement of U.S. Patent No.
5,978,791, entitled “Data Processing System Using Substantially Unique
Identifiers to Identify Data Items, Whereby Data Items Have the Same
Identifiers;” U.S. Patent No. 6,415,280, entitled “Identifying and
Requesting Data in Network Using Identifiers Which Are Based On
Contents of Data;” and U.S. Patent No. 7,802,310, entitled
“Controlling Access to Data in a Data Processing System.”
I'm pretty sure at least one member of this list used similar
techniques a decade ago for content management.
