The Brabham family has won its legal battle to protect the Brabham name through the German Higher Courts.
Sportscar racer David Brabham, the son of three-time Formula 1 champion and team founder Jack, had sued Michael Trick following his refusal to cancel certain registrations within the European Union involving the Brabham name in Germany.
Trick had been marketing road cars under the Brabham Racing banner.
The Brabham family announced on Wednesday the legal action was entirely successful and that the Brabham trademark registration is now reverted to the family's ownership.
"I'm delighted that this situation has finally come to an end," said David Brabham. "It's been a long and tiring battle, but this was something I felt we needed to do to protect the Brabham name.
"The global brand stands for success and innovation bolstered from 60 years of racing heritage, and deserves to be protected.
"This ruling will not only help future plans for the Brabham brand, but also protect the third generation of drivers, in Sam and Matthew, coming up through the ranks."
Back in 2009, a group set up by Formtech founder Franz Hilmer said that it had lodged an entry for the 2010 F1 world championship using the Brabham Grand Prix moniker. Its application was unsuccessful.
