The company said it complies with about 97 percent of the take-down notices.
Von Lohmann said it takes an average of 11 hours to respond to take-down requests, but that Google also tries to catch "erroneous or abusive removal requests."
He explained that a "major entertainment company" recently asked Google to delete a search result of a newspaper review of a TV show that included no infringing content. He said some companies use content removal for anti-competitive purposes or to remove unflattering content.
Google released the figures as part of a new website to provide more transparency about how it complies with copyright law.
Google was one of the leading opponents of controversial anti-piracy legislation earlier this year. The House's Stop Online Piracy Act (SOPA) and the Senate's Protect Intellectual Property Act (PIPA) would have forced Google and other search engines to delete links to entire websites if they were deemed "dedicated to copyright infringement."
Under current law, Google only has to delete links to the infringing content itself — not the entire website hosting it.
During the battle over the anti-piracy legislation, supporters of the bill, including Rep. Lamar Smith (R-Texas), accused Google of enabling piracy. In one statement, he accused Google of making billions of dollars by "working with and promoting" pirate sites. He said the company had a "vested interest" in stopping Congress from cracking down on online piracy.
Congress dropped the legislation after a massive protest led by Google and other Web companies led to a backlash of voter anger over the issue.
