Apple has been ordered by London's Court of Appeal to pay $502 million to U.S. patent holder Optis Cellular Technology for the use of 4G patents in iPhones and iPads.
Optis Cellular Technology sued Apple in 2019 over patents it claims are essential to certain technological standards like 4G.
Apple plans to appeal the court's decision while Optis vows to continue defending its intellectual property.
The Court of Appeal's ruling recognizes the high value of Optis' patents and orders Apple to pay over $700 million, citing Apple's significant negotiating strength as giving it an unfair advantage.
