General Motors has filed an application to register LT5 as a trademark with the United States Patent and Trademark Office (USPTO), GM Authority has discovered.

The automaker’s September 19th, 2016 application is assigned serial number 87175676 and specifies that the mark will be used to name “Engines for automobiles, sport utility vehicles, trucks and vans.”

This is the second time time that General Motors has applied for the LT5 trademark, with the first time being on April 2nd, 2013.

The GM Authority Take

This second trademark filing fans the rumor flames that peg LT5 as a forthcoming GM V-8 engine destined for duty in the upcoming C7 Corvette ZR1, which is said to make over 700 horsepower.

We believe that the reason for GM’s second filing for the LT5 mark is directly associated with the automaker’s true desire to secure rights to the mark, but unfortunately running out of time to do so using the original 2013 application.

It’s worth noting that, to successfully register a trademark, an applicant bears the burden to prove to the USPTO that the name for which it is filing (in this case — LT5) is a real-world product or service. This is performed via a document called Statement of Use, a vital element of the trademark application process that the applicant has up to three years to provide to the office.

To note, the LT5 mark was re-filed concurrently with the a trademark application for LTX.
