Following up on Lexus Enthusiast's news
regarding the RC350 being trademarked in Australia, we find that, unlike the CT300 which was only trademarked in Australia, Toyota Motor Corporation applied on November 2, 2012 for the trademark RC350 in the United States for use in association with automobiles and structural parts thereof.
United States Trademark Application No. 85770097 for RC350.
No word on the trademark in Canada yet. The database is updated weekly on Thursdays and there is some lag time between filing and publication on the database.
