US patent licensing company Adeia formally filed multiple patent infringement lawsuits against AMD in the Federal District Court for the Western District of Texas on November 3, accusing AMD of using unauthorized technology in chip design. Adeia stated that the lawsuit covers a number of patents related to semiconductor manufacturing and bonding, with the Hybrid Bonding technology used in 3D V-Cache being the main focus of the dispute.
Adeia stated that AMD's products have "borrowed heavily from Adeia's innovations" over the years, and these technologies "contributed significantly" to AMD becoming the market leader. The company pointed out that it had repeatedly tried to resolve the dispute through licensing negotiations, but after years of failed negotiations, it decided to take legal action to prevent AMD from continuing to use its patents without authorization.
Adeia currently has more than 13,000 global patent assets covering the media and semiconductor industries. Its representative technologies include DBI (Direct Bond Interconnect) and ZiBond, which have been widely licensed to many memory, image sensor and 3D NAND manufacturers. The company focuses on the development and licensing of intellectual property and is classified by the industry as a "non-patent practicing entity" (NPE), which means it does not directly participate in product manufacturing but earns revenue through patent licensing and protection.
In the past, Adeia has also had patent disputes with NVIDIA, and finally reached an out-of-court settlement with confidentiality terms in 2023. If this lawsuit against AMD is supported by the court, it may redefine the patent ownership of 3D packaging and bonding technology, affecting the future licensing evaluation and market competition of architectures including Ryzen, EPYC, and Intel Foveros Direct.
Adeia has asked the court to order AMD to stop using the technology and pay undisclosed damages. AMD currently has the option of settling with Adeia out of court, paying to obtain a license, or entering lengthy litigation proceedings. Although the probability of a short-term kernel ban is low, if the lawsuit continues to develop, it may still cause the sales of 3D V-Cache products to be restricted or face high compensation. .
