Patent Suits Hit Samsung, SK hynix and Now Seoul Semiconductor

The surge in U.S. patent litigation against Korean chipmakers is primarily driven by NPEs, which acquire patent rights without engaging in manufacturing. These entities then seek to generate revenue through infringement claims. Their focus has shifted towards large companies like Samsung and SK hynix, particularly as these firms are projected to achieve high operating profits during the current semiconductor market upturn, making them attractive targets for financial settlements or damages.

This trend is further fueled by a U.S. policy environment that has strengthened protections for domestic patent holders since the Trump administration. A notable consequence is the U.S. Patent and Trademark Office's increased tendency to decline inter partes review (IPR), a key defense mechanism for companies facing patent suits. This policy shift has emboldened U.S. NPEs, making it more challenging for Korean companies to effectively challenge infringement allegations.

Korean firms face a unique disadvantage in these legal disputes because NPEs do not produce goods. While manufacturers can often retaliate against rivals with countersuits using their own patents, this option is unavailable against NPEs. Consequently, companies frequently choose to settle, even when they dispute infringement, to avoid the substantial costs of litigation and potential damage to their corporate image. This dynamic incentivizes NPEs to continue filing suits.
