Kaspersky filed suit against GBAS seeking a declaration that it does not infringe three GBAS patents related to remote authorization to unlock electronic data. In October of last year, GBAS had filed suit accusing Kaspersky of infringing the three patents; GBAS never, however, actually served the complaint, and instead dismissed it without prejudice at the 90-day service date. The patents have since expired. Kaspersky notes that GBAS acquired the three patents sometime in 2017, and has filed twelve complaints asserting these patents, with all of them voluntarily dismissed before any accused infringers filed a responsive pleading. Kaspersky suggests that GBAS has sought nuisance-level damages, a classic patent troll tactic. Kaspersky further asserts that GBAS knows that Kaspersky does not infringe because arguments made during prosecution foreclose a claim construction that would cover Kaspersky’s software. To that end, Kaspersky seeks a declaration of non-infringement and a finding that the case is exceptional under 35 U.S.C. § 285, entitling them to attorneys’ fees.
