The festival founders maintain a website and social network channels using the mark, despite folding in 2013 and losing rights to the mark.
LL Cool J is taking legal action against the founders of the now-defunct Rock the Bells music festival, accusing the company of trademark infringement, cyber piracy and more for maintaining a website and several social media channels using the same name of his 1985 hit single.
"Rock the Bells" was the third single off LL Cool J's debut album, Radio, and peaked at No. 17 on the Hot R&B/Hip-Hop Songs chart. The rapper -- whose real name is James Todd Smith -- has since used the mark on merchandise and last March launched his own Rock the Bells channel on SiriusXM.
Meanwhile, the Rock the Bells festival ran from 2004-2013, initially launching in Southern California and expanding to country-wide tours with international iterations.
