On January 14, 2016, the Patent Trial and Appeal Board (PTAB) rejected six petitions for inter partes review (IPR) filed by Symantec, in which the company had challenged five Finjan, Inc. patents (7,757,289; 8,141,154; 7,930,299; 8,015,182; 7,756,996). Symantec had sought to invalidate various claims in the challenged patents under both §102 and §103, arguing that prior art rendered the ‘182 patent obvious and that the ‘289, ‘154, ‘299, and ‘996 patents were both obvious and anticipated. However, for each petition, the Board ruled that Symantec failed to show that it had a reasonable likelihood of prevailing with any of its asserted grounds for invalidity, and thus had not met the threshold for institution.
