LOS ANGELES (AP) – Attorneys for Robin Thicke and Pharrell Williams are asking an appellate court to overturn a copyright infringement verdict against them over the 2013 hit song “Blurred Lines.”An opening brief filed with the 9th Circuit Court of Appeal on Wednesday contends the case should never have gone to trial and the verdict should be overturned, or a new trial ordered. The case centered on whether Thicke and Williams copied the Marvin Gaye hit “Got to Give It Up” for their hit song. Their filing contends the judge presiding over a weeklong copyright infringement trial gave jurors several improper instructions. The trial ended with jurors awarding Gaye’s family more than $7 million. The verdict was later trimmed to $5.3 million. The Gaye family’s attorney did not immediately return an email seeking comment.
