Teradyne Robotics Files Patent Lawsuit Against JAKA Robotics in Europe
The maker of Universal Robots cobot arms is taking its Chinese rival to a European court over three patents covering robot joints and user interfaces. Here is what is at stake.
Key points
- Teradyne Robotics filed a patent infringement case against JAKA Robotics GmbH at the Unified Patent Court on Aug. 24, 2026.
- The lawsuit centres on three Universal Robots patents covering robot joint design and programmable user interfaces, all with a March 2006 priority date.
- JAKA's German subsidiary, the European arm of the Chinese robotics firm, is the named defendant.
- This is Teradyne's second major lawsuit against a Chinese robotics company in Europe in 2026, following a February copyright case against Elite Robots.
- JAKA says its own legal analyses found no infringement, and as of Sept. 2 its advisers hadn't confirmed any court proceedings were open.
Teradyne Robotics A/S, parent company of Universal Robots and the world's biggest maker of collaborative robot arms (compact, flexible machines designed to work alongside people on factory floors), filed case UPC-CFI-0003057/2026 at the Unified Patent Court's Copenhagen division. The UPC, launched in 2023, lets a patent holder sue across multiple EU countries with a single filing. We first reported on this dispute on 27 August, when Teradyne announced the case publicly; the docket shows the filing actually happened three days earlier.
What exactly is Teradyne claiming?
The suit targets JAKA Robotics GmbH and covers both hardware and software across a broad range of JAKA's European cobot sales.
Three patents sit at the centre of the case:
| Patent | Title | What it covers |
|---|---|---|
| EP1996376 | Programmable Robot and User Interface | A touchscreen showing operators a 3D robot model and letting them control movements |
| EP3045273 | Joint for a Robot | A safety brake inside a robot joint, using a solenoid and ratchet mechanism |
| EP3530420 | Joint for a Robot | Robot-joint construction, including output flanges connecting adjacent sections |
All three patents are assigned to Universal Robots and carry a March 2006 priority date, meaning this technology was being developed and protected two decades ago. Teradyne hasn't said publicly which specific JAKA models it believes infringe which patents.
What does JAKA say?
JAKA pushed back hard. After Teradyne announced the lawsuit on Aug. 27, JAKA said it had received no official notification from the court or from Teradyne. On Sept. 3 the company issued a statement saying its legal advisers confirmed no proceedings appeared to be open as of Sept. 2.
The discrepancy is probably procedural. Filing a case and formally serving the defendant are two separate steps, and a gap of days or weeks between them isn't unusual.
JAKA also pointed to two previous Freedom-to-Operate analyses, legal reviews a company commissions to check whether its products could infringe existing patents, which it says found no potential infringement involving Universal Robots technology.
Why does this matter beyond two robot companies arguing?
This is the second time in 2026 that Teradyne has sued a Chinese robotics firm in Europe; it filed a copyright case against Elite Robots' German subsidiary in February. That's a pattern worth watching for any business buying cobots in Europe. If Teradyne wins injunctions, the selection of competitively priced Chinese robot arms available on the continent could shrink quickly. Teradyne's own financial trajectory, including a 33% revenue jump in a single quarter this year, gives it the resources to sustain a long legal fight.
First reported by The Robot Report, the case docket currently lists 128 documents, none of them yet public.
Honest takeaway: If your business is evaluating cobot suppliers, ask any vendor for their Freedom-to-Operate documentation before you commit to a platform. A cheap machine that gets pulled from the market mid-contract isn't a bargain.
