Chad Hugo andPharrell Williamsare locked in a legal battle over The Neptunes name.

In a trademark opposition filed last week at a federal tribunal, Hugo, 50, claims that the producer/fashion designer, 50, is “fraudulently” looking for sole control of the trademarks, which violates the pair’s agreement to split everything equally.

In a statement to PEOPLE, a rep for Williams says that they have tried to offer ownership to Hugo.

In the notice of opposition, Hugo’s attorneys claimed that the “Happy” artist had “knowingly and intentionally” filed for those trademark applications without consulting Hugo, despite being “fully aware” that his partner should have been listed as a co-owner.

“Nothing, either written or oral, provided Williams or [PW IP Holdings] with the unilateral authority to register the trademarks,” they claim in the documents.

Hugo’s attorneys allege they’ve “repeatedly” reached out to Williams' team about the issue, and that Williams' “admitted that [Hugo] is equal co-owner of the trademarks” and promised to include him — a claim that reflects a statement from Williams' rep.
