On June 27, 2005, the U.S. Supreme Court held that a company can violate the copyright laws when it provides file-sharing software that allows others to illegally copy and disseminate copyrighted music and films on the Internet. The decision addressed several important and previously undecided copyright law issues. WLF had filed a brief in November 2004, urging the Court to address those issues; but WLF did not take a position on how the issues should be decided. The Court ruled against Grokster — a company whose software enables computer users to share copyrighted music and film files without paying any royalties — but its ruling targeted only those companies whose business plans are predicated on copyright violations and thus is unlikely to inhibit developers of legitimate, innovative software products.
