Key takeaways
- Teradyne Robotics sued JAKA’s German unit in 2026 for patent infringement covering both hardware and software.
- The case follows a February 2026 copyright suit against Elite Robots and a Hamburg injunction that blocked Elite’s software in Germany.
- A UPC ruling could apply to 17 of the 18 participating EU members, plus the UK and Spain.
- Both parties market cobots with overlapping payload and reach specs (e.g., JAKA Zu12 12 kg/1,327 mm vs. UR8 10 kg/1,750 mm).
- Teradyne reported $100 million revenue in Q2 2026, underscoring the financial stakes of IP protection.
The lawsuit at a glance
In 2026, Teradyne Robotics – the owner of Universal Robots – filed a patent infringement complaint against the German subsidiary of Chinese robotics firm JAKA. The complaint alleges that JAKA’s collaborative‑robot arms infringe multiple patents that protect significant hardware and software elements of Universal Robots’ products.
The dispute is the second high‑profile case Teradyne has launched in Europe that year. Earlier, in February 2026, the company brought a copyright action against Elite Robots’ German subsidiary. That case resulted in a preliminary injunction in April, with the Regional Court of Hamburg ordering Elite Robots Germany to stop offering the contested software and related products within the country.
Jurisdiction and potential reach
Teradyne filed the JAKA case with the Unified Patent Court (UPC) Local Division in Copenhagen, citing alleged infringement activities in Denmark and other EU member states. Teradyne notes that a UPC judgment could be enforced across 17 of the 18 participating EU members and could also extend to non‑UPC signatories such as the United Kingdom and Spain.
Statements from the companies
Jean‑Pierre Hathout, President of the Teradyne Robotics Group, framed the action as a broader defense of the company’s IP portfolio, saying the firm will “enforce its patents and intellectual property (IP) rights against what we consider to be illegal and unfair copying and infringement, across both hardware and software.”
David Brandt, Vice President of R&D and CTO of Universal Robots, clarified that the JAKA case is a patent matter, unlike the earlier copyright suit. He emphasized that “multiple patents … cover both significant hardware and software aspects of our products.”
Brandt also pointed out visual similarities between the two companies’ arms, noting that “our robots and the robots of JAKA look quite alike.” He stressed that the dispute is not about JAKA’s Chinese ownership: “to us, it’s not about China … it’s about other companies copying stuff that we designed, whether they’re Chinese or not.”
On the desired outcome, Brandt said the primary goal is to stop copying rather than to seek a cash settlement: “Ideally, we would like them to stop copying and infringing our IP. This is not predominantly for getting money out of JAKA.”
He raised safety concerns, warning that “if they are not as safe as they should be … there’s a risk that this could reflect badly on the entire industry.”
What’s on the table: payloads and reach
Both firms sell a wide range of collaborative robots. The following table lists a selection of models that appear in public specifications:
| Manufacturer | Model | Payload (kg) | Reach (mm) |
|---|---|---|---|
| Universal Robots | UR8 Long | 10 | 1,750 |
| Universal Robots | UR30 | 35 | – |
| Universal Robots | e‑Series (range) | 3‑16 | 500‑1,300 |
| JAKA | Zu5 | 5 | 954 |
| JAKA | Zu12 | 12 | 1,327 |
| JAKA | Zu18 | 18 | 1,073 |
| JAKA | Pro16 (IP68) | 16 | 1,713 |
The table illustrates the overlap: JAKA’s Zu12 carries a 12 kg payload with a 1,327 mm reach, while Universal Robots’ UR8 Long offers a slightly lower 10 kg payload but a longer 1,750 mm reach. JAKA’s Pro16, marketed for harsher environments with an IP68 rating, matches the upper‑end payload of Universal’s e‑Series while extending reach beyond 1,700 mm.
Financial backdrop
Teradyne Robotics reported $100 million in revenue for the second quarter of 2026. The figure reflects the scale of the cobot business and the monetary incentive to protect its technology portfolio.
How the dispute may shape the tooling market
Teradyne’s IP enforcement could influence OEMs and system integrators, who may need to evaluate the risk that copying core mechanical designs or software stacks could trigger litigation in multiple jurisdictions. The potential UPC ruling’s geographic coverage suggests manufacturers selling into Europe may have to assess patent exposure across several markets, not just the country of sale.
If the UPC were to invalidate JAKA’s contested models, the company would likely need to redesign mechanical architecture, embedded control software, or both—a process that could delay market entry and increase costs.
Conversely, the case underscores the value of a robust IP portfolio for original equipment manufacturers. Universal Robots’ ability to cite multiple patents across hardware and software gives it leverage in negotiations and may encourage customers to prefer officially licensed solutions over lower‑priced copies.
Outlook
The litigation is ongoing, and the final ruling will determine how far the UPC’s cross‑border enforcement reaches. For investors and industry professionals tracking collaborative‑robot tooling, the case highlights the importance of monitoring IP strategy as a component of product competitiveness.
Teradyne Robotics’ $100 million Q2 2026 revenue figure provides a concrete gauge of the financial stakes tied to protecting that strategy.
