KATY PERRY and her producing partners have to pay up in a copyright infringement case over her 2013 song “Dark Horse.”

A federal jury in Los Angeles on Thursday decided that the group must pay nearly US$2.8 million in damages to Flame, whose real name is Marcus Gray, because they determined parts of “Dark Horse” closely resembled “Joyful Noise,” a Christian rap song of Gray’s from 2008.

The jury determined that 22.5 percent of the profits from “Dark Horse” were owed to “Joyful Noise.”

According to the verdict, Perry must pay just over US$550,000. Her label, Capitol Records, has to pay nearly US$1.3 million. Perry’s five collaborators on the song were also ordered to pay, including producer Max Martin, who owes US$253,000, and Dr. Luke, who was ordered to pay US$61,000. Luke’s company, Kasz Money Inc., owes US$189,000.

Perry, listed in the verdict as Kathryn Elizabeth Hudson, made almost US$2.5 million in profits from the song, according to court filings in the case.

A nine-person jury reached a unanimous decision in the case. Her attorney said the pop star would appeal the verdict.

Perry’s attorneys argued, in part, that the portion in question was too common and brief to be protected by copyright, Rolling Stone reported. Flame argued that “Dark Horse” infringed on his copyright by using an underlying beat from his song without permission, according to court filings. “Dark Horse” held the No. 1 spot on Billboard’s Hot 100 chart for four weeks in 2014.

The case joins a growing list of high-profile copyright battles in the music industry in recent years. The family of Marvin Gaye, who died in 1984, went after Robin Thicke along with Pharrell Williams and rapper T.I., the collaborators on the smash-hit 2013 single “Blurred Lines.”

T.I. was cleared from the suit, but Thicke and Williams were ordered in 2015 to pay Gaye’s estate more than US$7 million on the grounds that their song infringed on Gaye’s 1977 hit. That judgment was reduced to US$5.3 million and the pair appealed the verdict.

Last year the five-year court battle ended with Gaye’s family being awarded a final judgment of nearly US$5 million.(SD-Agencies)
