Beyonce straight-up jacked the Roc-A-Fella logo and slapped it onto one of her music videos ... so claims the guy who claims he designed the logo.
Dwayne Walker says Queen B never asked permission to prominently display the logo in B's "Drunk in Love" music video ... and now he wants the court to put a stop to it and cut him a slice of the profits.
According to the docs ... Dwayne says he owns the rights to the original Roc-A-Fella logo and it shouldn't have been used in her music vid.
It's interesting ... we took a look at the video and the only time you see anything even resembling the logo is a quick shot of Jay Z's glitzy pendant. The rapper's not named or mentioned in the suit.
It's also worth noting Dwayne sued Jay for $7 million over the logo but lost the case back in September.
We've reached out to Bey's reps ... so far no word back.
