German carmaker Daimler AG may be slapped with a sales ban for its Mercedes-Benz cars in Germany after Finnish tech company Nokia won a patent dispute in a local court.

Judges in Mannheim ruled that Mercedes-Benz violated Nokia’s mobile-technology patents in its cars by using the company’s cellular technology without a license. This gives Nokia leverage in its fight with the carmaker over mobile technology used in new vehicles, ultimately enabling it to stop Mercedes-Benz from selling vehicles in Germany.

As you can imagine, this is not that simple to accomplish. According to Bloomberg, if it really wanted to impose a sales ban on Mercedes cars, Nokia would have to instigate a separate proceeding and post collateral of €7 billion ($8.3 billion) to enforce it. The sum would be used to cover massive damages in case the injunction was overturned on appeal.

The Mannheim court said the case was granted because Daimler was not willing to abide to the rules. In a statement, the court said “the facts show that Daimler and its supporters in the case aren’t willing to take a license” from Nokia under the industrywide fair-terms standards.

According to the ruling, Daimler also must communicate to Nokia the number of automobiles it sold with the technology. The automaker seems confident a sales ban is not going to happen, though. “We cannot understand the verdict of the Mannheim court and will appeal. We don’t assume there’ll be a sales ban,” the carmaker said in an emailed statement.

The dispute is part of a wider battle between tech companies and the automotive industry over royalties for technologies used in navigation systems, vehicle communications and self-driving cars.

Automakers in Europe are becoming increasingly dependent on mobile-telecommunication systems to enable e-connectivity on their vehicles. According to Reuters, Nokia makes €1.4 billion ($1.67 billion) in licensing revenues every year, so this issue is crucial for the Finnish company.

“We hope that Daimler will now accept its obligations and take a license on fair terms. There is more to gain if we work together,” Jenni Lukander, president of Nokia Technologies, said in a statement, adding that “innovators should receive a fair reward for the use of their inventions.”

Nokia changed its model to deal directly with automakers, cutting its interactions with suppliers. As a result, some suppliers, including Continental and Bosch, support Daimler in the litigation as associated parties.
