Comprehensive Analysis of Third-Party Defendants in U.S. Patent Litigation
Manufacturing companies are frequently drawn into U.S. patent litigation as third-party defendants by purchaser defendants accused of infringing patented products. This scenario is particularly common for Korean companies that supply key components to U.S. manufacturers, making them vulnerable to such legal disputes.
On December 12, 2024, Judge J. Nicholas Ranjan of the U.S. District Court for the District of Delaware granted a motion filed by Samsung Electronics, ordering third-party defendant Seoul Semiconductor to produce documents as part of the discovery process. This ruling highlights a typical example of third-party involvement in U.S. patent litigation, underscoring the challenges faced by many Korean manufacturers. (Seoul Wire article)
Given this reality, Korean manufacturers must carefully assess their legal status as third-party defendants, develop strategic litigation responses, and prepare for discovery obligations. To assist companies in addressing these challenges, I have prepared an eight-part blog series offering in-depth guidance for legal practitioners managing patent litigation strategies.
This blog series is available in both English and Korean, allowing readers to select their preferred language for review. While the examples reference specific companies involved in litigation to facilitate understanding, these scenarios are intended to illustrate broader legal principles and strategies rather than focus on the named parties.
