Apple Faces Antitrust Trial as Watch Patent Disputes Persist

By Dr. Graph | Published on Mar 31, 2026 | risk

Apple is navigating two distinct legal fronts—an iOS-related US antitrust case moving toward trial and an ongoing US trade/patent dispute involving Apple Watch import restrictions—while also reshaping parts of its supply chain under onshoring pressure. Together, these risks can affect timing of product decisions, potential remedy outcomes, and cost/operational flexibility.

DOJ’s iOS antitrust case: trial timeline risk for iOS economics

In 2024, the US Department of Justice filed an iOS-related antitrust suit against Apple, and it is “slowly moving toward trial,” with judges reportedly “leery of ordering drastic remedies even if companies are declared monopolies” [1]. For investors, the financial logic is that antitrust remedies—whatever their final scale—can force changes to iOS distribution or platform conduct, which can create uncertainty around iOS ecosystem economics and the cost/timing of compliance and product adjustments [1].

Onshoring pressure pushes US supply-chain buildout, but iPhone production stays abroad

Apple is working with additional global suppliers—including TDK, Bosch, Cirrus Logic, and Qnity Electronics—to make advanced parts (such as sensors, semiconductor materials, and integrated circuits) and is moving “chips and glass” to US production through partnerships with TSMC and Corning, as part of a larger plan supported by a “$600bn investment commitment” [2]. The business logic is that onshoring efforts can raise execution and supplier-risk complexity while also exposing Apple to uneven policy incentives; notably, iPhones are still “mostly made in China and India,” meaning geopolitical and trade-policy risk remains in production even as some higher-value components shift [2].

Masimo’s Apple Watch patent win: import-ban risk and financial exposure

Masimo sued Apple in California federal court for patent infringement and trade-secret theft and won $634 million in a November patent trial; Apple said it would appeal [3]. Separately, the US trade tribunal (ITC) matter moved as the US Court of Appeals for the Federal Circuit affirmed a decision that blocked a renewed bid for an import ban on Apple Watches that infringe Masimo’s patents, with Apple altering watches to circumvent an import ban issued in 2023 [3]. The financial logic is that adverse patent outcomes and ITC import-ban threats can constrain smartwatch sales channels and trigger damages and legal costs, while design-around outcomes can reduce infringement risk but keep the dispute lifecycle—and associated uncertainty—active until appeals and related decisions conclude [3].

Frequently Asked Questions

What is the current status of the DOJ iOS antitrust suit against Apple?
The DOJ’s iOS-related antitrust suit filed in 2024 is “slowly moving toward trial,” though judges may be “leery of ordering drastic remedies even if companies are declared monopolies” [1].
How is onshoring pressure changing Apple’s supply chain, and what portion of iPhone production remains outside the US?
Apple is working to move some advanced parts to US production by expanding partnerships with suppliers (including TDK, Bosch, Cirrus Logic, and Qnity Electronics) and moving “chips and glass” to US production via TSMC and Corning, but iPhones are still “mostly made in China and India” [2].
What happened in Masimo’s patent case against Apple and how does it affect Apple Watch import ban risk?
Masimo won $634 million in a November patent trial; Apple said it would appeal [3]. In a separate ITC/tribunal context, the Federal Circuit affirmed a ruling rejecting Masimo’s bid for a renewed import ban on redesigned Apple Watches, and Apple has since resumed importing its redesigned watches [3].
