Isohunt today filed its opening appellate brief to the Ninth Circuit Court of Appeals urging the court to provide better protection from mass copyright lawsuits to search engines, such as Isohunt, that do not store, touch, or distribute copyrighted works. "This case is about the freedom to search on the internet and whether web search engines have to preemptively censor user generated links and torrent data files or be subject to keyword filtering" says Ira P. Rothken counsel for the Isohunt defendants. Here is a news story at Techdirt and another news story on an industry site.
