The Invisible Threat to AMD’s Crown Jewels
The Defence and the Industry’s Perspective: A Battle of Giants (and Their Foundries)

While Adeia targets AMD, the ultimate manufacturing entity in question, TSMC, adds a layer of complexity and suggests a common industry strategy for these types of lawsuits.
Why Sue AMD, Not TSMC?
AMD designs the chips and sells them, but the actual Hybrid Bonding process is performed by their manufacturing partner, TSMC (Taiwan Semiconductor Manufacturing Company). TSMC is the world’s leading semiconductor foundry and performs the highly specialised 3D stacking for AMD. So, why isn’t Adeia suing TSMC directly?
- Strategic Target: Patent licensing companies often strategically target the end-product seller (AMD) rather than the manufacturer (TSMC). It’s easier to calculate damages based on AMD’s product sales and, crucially, to obtain an injunction that prevents AMD from selling their products. Getting an injunction against TSMC would impact dozens of other companies and be a far more complex legal battle. It also places pressure directly on AMD to secure a license, which they can then negotiate with TSMC if needed.
- Broader Impact: A successful suit against AMD could set a precedent that benefits Adeia in future negotiations with other companies utilising advanced stacking from TSMC or other foundries.

The Likely Outcome: Settlement over Showdown?
While the threat of an injunction is serious, full-blown injunctions that completely halt a major product line are rare in the semiconductor industry, especially against a company as significant as AMD.
- The Cost of Litigation: Patent litigation is astronomically expensive and can drag on for years, sometimes a decade or more. Both parties have an incentive to avoid this.
- The Adeia Business Model: Adeia’s core business is licensing. They want a steady stream of revenue, not a protracted legal war. Their primary goal is to force a “fair and reasonable arrangement” being a licensing deal. This means AMD would pay a fee (either a lump sum or ongoing royalties) to continue using the patented technology.
No Immediate Disruption Expected
Analysts largely agree that while the lawsuit is a significant development, no immediate disruption to AMD’s product supply (like X3D CPUs) is expected. The legal process is slow, and any injunction would be far down the road, if it happens at all. AMD will vigorously defend itself, but a licensing agreement is the most probable outcome. However, the cost of that agreement will inevitably impact AMD’s bottom line and, more than likely, this will have to be passed on to the consumer, so you could be expected to pay more for AMD products in the future.
