Hulk smash trademark infringement!

Puny power tool manufacturer, don't make Hulk angry. You wouldn't like him when he's angry.

THR, Esq., the Hollywood Reporter's entertainment law blog, reports that Marvel has sued a manufacturer that is using the name Hulk as a brand name for air compressors. Airbase Industries applied last year to register HULK as its own trademark for power and hand tools (USPTO serial number 77757650); Marvel has opposed that application. Marvel has now filed suit against Airbase in federal court, alleging trademark infringement and various other claims.
