Searching patent litigations

Surfing within patent legal data is not very easy, even if register data can do the job for EPO and for USPTO some free access data are available.

the site:

http://www.patentfreedom.com/

allows to use a easy interface for searching patent litigation procedures for USPTO.
A plus for this engine is the implementation of entity disambiguation and group structure that allows also to search by ultimate parent.
