Fulk's lawsuit claims that Beyonce's film is "substantially similar" to his 2014 short film "Palinoia", but Beyonce says the two films have completely different narratives, reported TMZ.
Beyonce's legal team filed a motion to dismiss, urging the judge to toss out Fulk's lawsuit.
"A straightforward comparison of the parties' works provides a textbook example of what does not constitute legally cognizable claim of infringement," read the motion.
"'Palinoia' is about a tumultuous relationship that is now over. The protagonist is a white male and his former lover is a white blonde woman. The demise of their relationship is oblique, and is not tied to infidelity," the motion continued.
Fulks is also said to have alleged that a Senior VP at Columbia Music, Beyonce's record label, saw "Palinoia" sometime in 2015 and he believes that executive stole his ideas to use for "Lemonade", which started shooting at the end of 2015.
