Arstechnica has today reported that Intellectual Ventures has just successfully asserted two of its patents in litigation against Symantec. These two patents were part of a trio of patents asserted in the same litigation, namely:

This has an AmberScore value (predicted patent importance) of 18.0, which is excellent and much higher than the average AmberScore value of 1.0 for granted US patents.

- US6073142, Automated post office based rule analysis of e-mail messages and other data objects for controlled distribution in network environments, filed in 1997. AmberScore value of 29.6.
- US646050, Distributed content identification system, filed 1999. AmberScore value of 21.1.
