Honda Motor Co. may file an appeal against a Chinese court ruling Wednesday that rejected Honda's request that Beijing's patent office reinstate a patent on a motor scooter design, Honda officials said Thursday.

"We are disappointed that our case was rejected," a Honda official said in reference to the court decision.

The carmaker filed the lawsuit against the State Intellectual Property Office last December at the No. 1 Intermediate People's Court; the office in September had revoked Honda's design rights, first obtained in 1994.
