Lady Gaga is asking to be reimbursed $232,484 (£172,183) in legal bills.
The singer spent the money defeating a lawsuit that claimed her Mayhem album infringed a brand of Mayhem surfboards.
She has dubbed the case a “publicity stunt”.
Lost Surfboards sued the star last year, claiming people who saw her album name would think it was somehow endorsed by the surf company. The case was rejected last month by a federal judge, who said no such confusion was likely.
In a scathing motion Friday, the new mum’s lawyers insisted she should not be forced to pay legal bills she racked up defending the case.
They assert it was “never a legitimate lawsuit” but instead an improper effort to “capitalise on the fame and popularity of Lady Gaga” by suing her over the use of “a common dictionary word”.
“A litigant should not be permitted to use the federal courts to launch a publicity stunt masquerading as a lawsuit against a high-profile artist,” Gaga’s attorney wrote in the filing, obtained and reported by Billboard.
“Nor should it be permitted to wield the machinery of litigation as a device for extracting a settlement that the merits cannot justify. This lawsuit was both.”
When they sued Gaga last year, Lost owners accused her of showing a “blatant disregard” of their company’s trademark rights, claiming that her stylised red Mayhem logo was similar to theirs.
Gaga previously scored a victory in the case in December, when a judge rejected Lost’s request to stop her from selling Mayhem-branded products.
