(Reuters) -Japanese automaker Nissan (OTC:NSANY) Motor Co and French automaker Renault SA (OTC:RNLSY) have agreed to restrict the use of the intellectual property they developed together in a new company established by Renault (EPA:RENA), a report by Nikkei said on Wednesday.
The sharing of technology had emerged as a sticking point between Renault and Nissan as the pair negotiated an overhaul of their decades-old partnership, Reuters reported in October.
The French and Japanese automakers have been in talks about the future of their alliance, including Nissan potentially investing in an electric vehicle business being spun out of Renault.
At the same time, Renault and China's Geely had agreed to launch a new, equally held joint venture code-named "Horse" that would supply gasoline engines and hybrid technology to the brands they own, as well as to other automakers.
Renault had told Nissan that it wanted to use patents and other IP jointly acquired with Nissan in the new venture, the report said citing sources.
However, Nissan had raised concerns about the treatment of IP, including battery and powertrain technology.
Nissan said it would not allow the use of joint IP for products to be offered in the United States and China to forestall competition with the new company and prevent technology leaks, the Nikkei report said.
Nissan wants to ensure that key internal-combustion and hybrid technology it owns is protected in any deal Renault strikes with Geely, Reuters reported in November.
Spokespersons for Nissan and Renault declined to comment.
