Speculation that the Lexus LF-A supercar project had been axed several months ago was refuted to some degree by ongoing testing of the car at the Nurburgring. Now a filing with the U.S. Patent and Trademark Office has breathed new life into the car's possible production, though the company still hasn''t officially confirmed the car.

The trademark filing, first dug up by AutoSpies, was made December 1, 2008. While information contained in the official document is understandably sparse, the name is registered for use as the name of 'automobiles and structural parts thereof'. Also of note is the absence of the hyphen previously found in the car's name, changing the name from LF-A to LFA.

Test versions of the car spotted in testing are believed to house a 5.0L V10 engine rated at 500hp (373kW). A company executive speaking earlier this year revealed that the car's price, if it did head to production, would "begin with a two." That puts the LFA in league with the Ferrari F430, Lamborghini Gallardo and similar exotics.

A roadster version could also be in the works, previewed by a concept version at the 2008 Detroit Auto Show.
