Editing Raging Bull (section)

=== Copyright litigation ===
Paula Petrella, heir to Frank Petrello, whose works were allegedly sources for the film, filed for copyright infringement in 2009 based on MGM's 1991 copyright renewal of the film. In 2014, the Supreme Court held, in ''[[Petrella v. Metro-Goldwyn-Mayer, Inc.]]'', that Petrella's suit survived MGM's defense of "[[laches (equity)|laches]]", the legal doctrine that protects defendants from unreasonable delays by potential plaintiffs. The case was remanded to lower courts, meaning that Petrella could receive a decision on the merits of her claim.<ref>Eriq Gardner, [https://hollywoodreporter.com/thr-esq/supreme-court-allows-raging-bull-705572 "Supreme Court Allows 'Raging Bull' Heiress to Sue MGM for Copyright Damages"] {{Webarchive|url=https://web.archive.org/web/20140522052032/http://www.hollywoodreporter.com/thr-esq/supreme-court-allows-raging-bull-705572 |date=May 22, 2014 }}, ''[[The Hollywood Reporter]]'', May 19, 2014.</ref> MGM settled with Petrella in 2015.<ref>{{cite news |title=After Supreme Court, MGM Settles 'Raging Bull' Rights Dispute |work=The Hollywood Reporter |date=April 5, 2015 |first=Eriq |last=Gardner |url=https://hollywoodreporter.com/thr-esq/supreme-court-mgm-settles-raging-786449 |access-date=June 25, 2015 |archive-url=https://web.archive.org/web/20150905135348/http://www.hollywoodreporter.com/thr-esq/supreme-court-mgm-settles-raging-786449 |archive-date=September 5, 2015 |url-status=dead }}</ref>
