SecurityProfiling, LLC v. Trend Micro Incorporated

Last July, the Federal Circuit summarily affirmed the invalidation of claims from one of several anti-malware patents asserted by SecurityProfiling, LLC in litigation against Trend Micro. The Patent Trial and Appeal Board (PTAB) had rejected SecurityProfiling’s claim to an early priority date, converting nearly a decade of references into prior art, dealing a blow to the plaintiff’s campaign: the Northern District of Texas case against Trend Micro was dismissed with prejudice this past October. It appears, however, that that blow was not fatal, as SecurityProfiling has filed another case against Trend Micro (6:21-cv-00330) and a first case against Cisco (6:21-cv-00337), both in the Western District of Texas this time and both asserting patents from the same family.
