Dale Earnhardt Jr, Lamar Jackson find themselves in court battle over famed number 8

Well, back in 2019, Jackson filed trademark registrations for "ERA 8" and "ERA 8 BY LAMAR JACKSON."

Dale Jr., however, is now attempting to trademark the number itself, stylized in the fashion it was on his car. He filed the application last December.

But Jackson argues that Earnhardt's application conflicts with his own trademarks.

In a notice of oposition, Jackson says that he is widely associated with the No. 8 "due to his notoriety and fame, along with his promotion of this number in his trademarks and in media coverage" and that he could be "damaged" by Earnhardt Jr.'s registration. 

The quarterback also said that the driver's registration "falsely suggests a connection" between the two.

Thus, the quarterback has "respectfully [requested" that Earnhardt Jr.'s application be "refused registration."

In his NASCAR career, Dale Jr. won two Daytona 500s and back-to-back Xfinity Series, then known as the Busch Series, to close out the 1990s.
