DJI Wins Patent Infringement Case at Unified Patent Court (UPC)

WISECODE Take

Many business owners mistakenly believe that facing overseas patent litigation only allows for passive defense. I believe this multinational battle is essentially a "joint legal operation" testing defensive depth and resource deployment. In military strategy, fighting in isolation is highly discouraged. Facing Irdeto's EP2831787 B1 patent lawsuit filed at the Unified Patent Court (UPC) on June 12, 2026, DJI demonstrated excellent defensive and counter-offensive coordination. DJI not only successfully argued in Europe that products like Mavic 3 did not infringe, but also challenged Irdeto's patents at China's CNIPA, successfully invalidating two of them. This "offense as defense" multi-country encirclement is the key to securing major products overseas. I suggest two actions: first, isolate open-source technologies from patented features during R&D; second, evaluate global multi-point counter-offensives when facing litigation to disperse the opponent's resources. The best defense is a precise overseas counter-strike; we recommend consulting and evaluating through our "Patent Portfolio Health Check" service to plan your defensive tactics.
