(Reuters) — Apple and its allies on Monday will kick off a jury demo from chip provider Qualcomm in San Diego, alleging that Qualcomm engaged in unlawful patent licensing tactics and trying to find up to $27 billion in damages.

Qualcomm, for its part, alleges that Apple compelled its longtime organization companions to give up paying out some royalties and is seeking up to $15 billion.

Filed by Apple in early 2017, the lawsuit in federal court docket revolves around the modem chips that join units like the Iphone or Apple Watch to wi-fi data networks. Qualcomm has put in the past two decades mounting a force campaign of lesser lawful skirmishes in opposition to Apple, trying to find — and in some conditions obtaining — Iphone revenue bans for violating its patents.

The trial prior to Choose Gonzalo Curiel will enjoy out on Qualcomm’s household turf of San Diego, exactly where for decades the city’s Countrywide Soccer League workforce performed in Qualcomm Stadium and virtually each and every business enterprise district hosts the cell chip firm’s symbol.

For Apple, the trial is about the freedom to figure out its personal technologies route for blockbuster merchandise by shopping for chips with out acquiring to pay back what it calls a “tax” on its innovations in the type of patent licensing charges to Qualcomm that take a slice of the promoting value of its equipment.

For Qualcomm, the trial, along with equivalent allegations from U.S. regulators in a January court docket listening to, will figure out the fate of its exclusive mix of offering chips and licensing additional than 130,000 patents.

Licensing generates most of Qualcomm’s profits. The model propelled Qualcomm from a little contract investigation and development shop when founded in 1985 to a global chip powerhouse significant adequate to U.S. countrywide stability that President Donald Trump personally intervened to stop a hostile takeover of the corporation last calendar year.

“This is the day of reckoning that Qualcomm has been quite fortuitous to stay clear of for numerous years,” mentioned Gaston Kroub, a patent lawyer with Kroub, Silbersher & Kolmykov who is not included in the scenario. “In Apple, they’ve at last arrive up versus a probable licensee that has the resources and the will to put Qualcomm’s small business design and licensing tactics on demo.”

Qualcomm demands unit makers to sign a license to its patents just before it will source chips, which it views as a commonsense measure to make sure it does not do enterprise with corporations violating its patents. But Apple and other machine makers around the globe have known as the “no license, no chips” coverage a kind of “double dipping” — that is, charging for the exact same intellectual property at the time through licensing discussions, and then all over again in the price of the chips wherever the patents are embodied.

Apple and allies are asking for an finish to that practice and a refund of about $9 billion — an amount of money that could be tripled if a jury finds in Apple’s favor for antitrust allegations — for agreement factories this sort of as Foxconn, who compensated the royalties and were reimbursed by Apple. Apple alleges the methods retained rivals like Intel out of the market for many years.

“Even very major organizations like Intel have felt at a drawback,” stated Michael Salzman, an antitrust legal professional with Hughes Hubbard & Reed not included in the scenario.

Qualcomm will argue that it had been doing the job correctly with contract factories for several years before Apple released its Apple iphone. But Apple made use of its heft in the market to get individuals factories to crack their longstanding contracts with Qualcomm, depriving it of at minimum $7 billion in royalties it was thanks, the chip provider alleges.

The chip provider will also argue that its licensing techniques have been steady for decades and only came beneath fire when Apple, recognised in the electronics market for pushing suppliers to have expenses, took challenge with it. A victory would protected Qualcomm’s standing as a major technology supplier for 5G, the future technology of cellular details networks coming on line this 12 months.

“I never think (a Qualcomm victory) would be fantastic for Apple, but if it is about dollars, they’ve obtained loads of income,” explained Stacy Rasgon, an fairness analyst for Bernstein who follows Qualcomm. “For Qualcomm, it’s an existential assault on the meat of their business enterprise model.”
