Adeia are known Patent Trolls, they are looking for a quick easy payout from a company flush with cash, they will lose....
The 3D packing technology was a partnership between AMD and TSMC, AMD have responded to this saying there is no detailed patent that Adeia hold, it is simply a vague idea about stacking chips, something that has been an idea since long before Adeia existed. AMD/TSMC created the technology to make the idea reality. It consists of specific circuitry design (AMD) and packaging (TSMC) these things are specific to their technologies, AMD's circuitry cannot be transplanted in to another CPU because its part of the CPU's design.
In fact the first 3D Stacking tech was HBM memory, again AMD designed it in partnership with SKHynix, 2013, Adeia was founded in 2022 purely to file patents of existing technology and then try to extract money from the people who created those technologies. Adeia could not have invented a technology that was in use 9 years before they existed, Patent Trolls.

Its gone to court because AMD refuse to pay them a penny, i hope AMD bleed them dry. Patent Trolls are a cancer to innovation. Like Musk AMD should counter sue them for some BS and like that make them drain finances defending it.
