It’s taken nine years, two judges, multiple law firms, a jury trial and a couple of detours to the U.S. Court of Appeals for the Federal Circuit. But Adobe Systems Inc. is finally out of a lawsuit over encryption patents, with zero damages.

TecSec Inc., a company founded by a former director of the CIA’s Cryptographic Center, has been pursuing Adobe and several other technology giants in the Eastern District of Virginia since 2010, accusing them of infringing its patents on multilayered encryption. TecSec argued at trial that Boeing had paid $10 million for a license and Microsoft paid $16.5 million to settle previous litigation, but that Adobe had been trying to “wait out” TecSec’s three founders, who are in their 70s and 80s.
