Apple Inc. filed petitions challenging four Qualcomm Inc. patents, dragging the U.S. Patent and Trademark Office into a long-running licensing dispute that already spans the globe.

The two are locked in a bitter fight over the amount of royalties Apple’s suppliers should pay to use Qualcomm’s technology on telecommunications. Billions of dollars are at stake. A hearing in one case is under way at the U.S. International Trade Commission in Washington, and trials are scheduled for later this year in China and Germany.

Apple wants the patent office to cancel four Qualcomm patents, saying they don’t cover new ideas. All are part of a patent-infringement lawsuit Qualcomm filed in 2017 against Apple in federal court in California.

The patents being challenged involve ways to automatically focus a digital camera; a device that functions as both a phone and personal digital assistant; touch-sensitive displays; and circuit memory.

“These types of challenges are not uncommon in U.S. patent litigation,” Qualcomm General Counsel Don Rosenberg said. “We are confident in the validity of our patents, which Apple continues to infringe.”

Apple is one of the most aggressive users of the proceedings at the Patent Trial and Appeal Board, which has an easier legal standard than courts do, and frequently seeks to invalidate patents when it’s been sued for infringement. The iPhone maker has filed 398 petitions challenging patents, according to the patent office’s electronic database.

Three judges with the review board will consider the petitions and any response from Qualcomm, and will make a preliminary decision on whether Apple has a chance of winning its arguments. If so, it will institute a formal review and issue a final decision in a year.
