AMD Hit With Lawsuit Alleging X3D Patent Infringement
Adeia Inc., the technology company known for developing foundational innovations in the semiconductor industry, announced today that it has filed patent infringement lawsuits against Advanced Micro Devices, Inc. (AMD) in the U.S. District Court for the Western District of Texas.
"Earlier today, Adeia took legal action against AMD to protect our intellectual property rights and the investments we have made in our foundational semiconductor technologies," said Paul E. Davis, chief executive officer of Adeia. "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."
In its filings today, Adeia alleges AMD infringes ten patents from Adeia's semiconductor intellectual property (IP) portfolio - seven patents covering hybrid bonding technology and three patents covering advanced process node technology.
"We are confident that pursuing this litigation is the right course of action to protect Adeia's inventions, as well as the interests of our shareholders and customers," said Davis. "While we continue to be open to reaching a fair and reasonable arrangement that reflects the value of our intellectual property, we remain fully prepared to pursue resolution of this matter through the courts to safeguard our rights and firmly believe in our ability to achieve a successful outcome."
Over the past four decades, Adeia and its predecessor companies have continuously invested in research and development, resulting in one of the world's largest IP portfolios comprised of more than 13,000 worldwide patent assets. Today, Adeia's IP is broadly licensed across the media and semiconductor industries.

It's also ironic that they go after AMD for node and bonding related patents. AMD is a fabless semiconductor company.
They design, but do not produce the wafers. Shouldn't the troll go after TSMC instead?
Do we know exactly what is this about?
...
will these damages count as "global semiconductor sales" for SIA's statistics (see the TPU news post just before this one)?
And I imagine Intel, Nvidia and IBM are also on the list for future targets.
So why litigate now? your company in need of some cash?I thought TSMC came up with 3D vcache
Unfortunately for Adeia, 5800X3D was released on April 20th, 2022.
AFAIK, TSMC developed their stacking technology back in 2020.

One particular patent tied to TSV technology was filed in 2019 but TSV itself was used long before (stacked DDR3 RAM dies, CMOS sensors).
How to Defend Against Patent Trolls
Or maybe not, Adeia stock is down about 15% today by the look of it.
