The lawsuit, filed on April 6th with the Texas Eastern District Court, comprises phones from the Galaxy S6 all the way to the Galaxy S8. PACid alleges that two US patents (U.S. Patent No. 9,577,994 and No. 9,876,771) and one South Korean patent (KR20110128567A) have been infringed upon. In addition to the biometric systems onboard, Samsung Pass and Knox are also involved in the suit. PACid says that Samsung has known about its patents since January 2017 at the latest. Should the court accept that claim, Samsung will have to pay up to three times the standard rate of $1 per phone (35 U.S. Code § 284), or 2.82 billion USD (3 trillion KRW) in total.
