Teradyne Sues JAKA Over Collaborative Robot Patents in Europe
The parent company of Universal Robots is using the Unified Patent Court to block Chinese competitors from the European market.
Teradyne Robotics has launched a patent infringement lawsuit against JAKA Robotics GmbH, the German subsidiary of Chinese cobot manufacturer JAKA. The legal action, filed on August 24, 2026, marks a significant escalation in the battle for intellectual property dominance within the European collaborative robotics sector.
Filed at the Unified Patent Court (UPC) in Copenhagen under case number UPC-CFI-0003057/2026, the lawsuit alleges that JAKA's collaborative robots sold in Europe infringe on three specific patents. These include EP1996376, which covers programmable robots and user interfaces; EP3045273, regarding robot joints and safety brakes; and EP3530420, focusing on joint construction. Teradyne, the parent company of Universal Robots, has established a massive footprint in the industry, having sold more than 100,000 collaborative robot arms since 2005.
A Pattern of Aggression
This filing is not an isolated incident but part of a broader strategic push by Teradyne to protect its IP against emerging Chinese rivals. This is the second major legal move the company has made against a Chinese robotics firm in Europe this year. In February 2026, Teradyne filed a separate lawsuit against the German subsidiary of Elite Robots, though that case focused on copyright infringement rather than patent law.
Industry Implications
As the world's leading developer of cobots, Universal Robots is utilizing the UPC to set a legal precedent that could stifle the expansion of "copycat" hardware and software. By targeting core technologies—specifically joint construction and user interfaces—Teradyne is attempting to create a high barrier to entry for competitors. If the court finds that JAKA's core technologies are infringing, it could severely limit the ability of Chinese robotics firms to scale their operations or maintain their current footprint across European markets.
The Path Forward
JAKA Robotics has addressed the situation through a statement from its legal advisers on September 2, noting that prior to this action, no court proceedings concerning the alleged infringement had been filed or opened against the company. The industry is now watching the Copenhagen Local Division of the UPC to see if Teradyne can successfully enforce these patents. A victory for Teradyne would likely signal a more litigious environment for any non-Western robotics firm attempting to enter the European cobot market.
