After an eleven day trial before Chief Judge Gregory M. Sleet, a jury recently returned a defense verdict in litigation involving computer security products. Finjan, Inc. v. Symantec Corp., et al., C.A. No. 10-593 (GMS) (D. Del. Dec. 20, 2012). The jury found that none of the three defendants literally infringed the patents asserted against them, and that every asserted claim of those patents was invalid in any event as both anticipated and obvious.
