Adeia Files Lawsuit Against AMD for Semiconductor Patent Infringement, Targeting Advanced 3D Stacking Technology in Ryzen X3D Processors

In a significant legal development, Adeia, a firm specializing in IP licensing, has initiated legal action against AMD, claiming the tech giant has unlawfully utilized its semiconductor patents in various product lines.

Adeia Takes Legal Action Against AMD Over Patent Infringement

Adeia has filed two patent infringement lawsuits in the US District Court for the Western District of Texas, asserting that AMD has leveraged its patented technologies for an extended period without obtaining proper licensing. The core of these claims revolves around innovations in hybrid bonding technology, crucial to the performance of AMD’s 3D V-Cache processors. This advancement has reportedly given AMD a competitive advantage in the CPU market, particularly against its rival Intel.

Adeia contends that the hybrid bonding technology has played a pivotal role in enhancing gaming performance and optimizing certain applications since 2022, contributing directly to AMD’s market leadership. Despite extensive negotiations over several years to establish a licensing agreement, Adeia claims that these discussions have not yielded any agreements, forcing them to resort to litigation.

For years, AMD’s products have incorporated and made extensive use of Adeia’s patented semiconductor innovations, which have greatly contributed to their success as a market leader. After prolonged efforts to reach a mutually agreeable resolution without litigation, we believe this step was necessary to defend our intellectual property from AMD’s continued unauthorized use.

The lawsuits reference a total of ten patents, seven of which are related to hybrid bonding technology, while the remaining three entail advanced semiconductor processing methods. Although Adeia has initiated these legal proceedings, they have expressed a willingness to continue negotiations, indicating that they are “fully prepared”to advance the case in court if necessary. If the litigation proceeds, AMD could face considerable licensing fees, which may affect the pricing and production of products that utilize 3D-stacked packaging technologies.

The potential implications of this legal battle could have long-lasting effects on AMD’s strategic roadmap. As of now, AMD has not publicly addressed the lawsuit. It’s important to note that while AMD’s chips are produced by TSMC, the lawsuit specifically targets AMD, as Adeia views AMD as the key beneficiary of the patented technologies, rather than TSMC, which operates solely as a contract manufacturer. Patent disputes of this nature are prevalent within the semiconductor industry; however, the stakes are particularly high for AMD in this case due to the critical timing and the specific technologies involved.
