Songwriter Steve Ronsen has threatened to file a lawsuit against the singer, who wrote the Academy Award-winningA Star Is Borntrack with Andrew Wyatt, Anthony Rossomando and Mark Ronson.

Ronsen has alleged that a chord progression from his 2012 song “Almost” was stolen for the melody of “Shallow.”

“It is shameful and wrong,” he added. “I applaudLady Gagafor having the courage and integrity to stand up on behalf of successful artists who find themselves on the receiving end of such [claims]. Should Mr. Shirian proceed with this case, Lady Gaga will fight it vigorously and will prevail.”

In the statement, Snyder also wrote that “multiple leading musicologists” they contacted “found no actionable similarities between the two songs.”

“Even Shirian’s own musicologist acknowledged the generic three note progression is present in many other songs predating his client’s song,” he said.

Ronsen’s attorney, Mark D. Shirian, also released a statement toPage Six.

“In an effort to amicably resolve this matter months ago, my office providedLady Gaga’s legal team, at their request, with an official report from a renowned and respected musicologist and professor who determined that there are significant tempo, melodic, rhythmic and harmonic similarities between the two ‘hooks’ of the songs at issue,” Shirian wrote. “Lady Gaga’s team has yet to provide my office with an opposing musicologist report, which we have requested multiple times.”

Gaga’s attorney, Ronsen and Shirian did not immediately respond to PEOPLE’s request for comment.

News of the threatened lawsuit comes a week after a jury found thatKaty Perry’s 2013 track “Dark Horse”infringes on the copyright of a Christian rap song.

On July 29, a nine-member federal jury found that Perry’s hit track copied the Christian song “Joyful Noise,” released under Marcus Gray’s stage name, Flame. The decision came five years after Gray and two co-authors first sued.

Perry’s camp will have to pay $2.78 million in damages, although her record label Capitol Record will foot the majority of the bill.
