NEW YORK -- A federal judge handed Google Inc. a victory in a long-running legal battle on Thursday, tossing out a lawsuit claiming the Internet giant was violating copyright laws by scanning books without the writers' permission to create the world's largest digital library.
The 28-page decision by U.S. District Judge Denny Chin in New York is the latest twist in a circuitous journey that began nine years ago when Google set out to make digital copies of all the books in the world.
The ambitious project prompted the Authors Guild to sue Google in a Manhattan federal court in 2005, claiming the Mountain View, Calif.-based company was not making "fair use" of copyright material by offering searchable snippets of works in its online library.
The lawsuit was seeking $750 for each of the more than 20 million copyright books that Google has already copied. Google had estimated its damages could have surpassed $3 billion -- a significant blow even to a company with more than $56 billion in the bank.
Chin's ruling won't necessarily close the book on the case. The Authors Guild plans to appeal, opening the next chapter in a legal saga that some experts believe will ultimately land in the U.S. Supreme Court.
If the decision stands, Google's Internet search engine will be in a better position to become an even deeper reservoir of human knowledge.
As it expands its stockpile of digital books, Google's search engine is likely to be seen as an even more indispensable resource.
Although Google doesn't display ads next to the excerpts from digital books, anything that spurs people to think of its search engine as the best place to find information usually boosts the company's profits. That's because habitual use of Google's search engine typically produces more opportunities to show the ads that generate most of the company's revenue.
Chin conceded Google might make money from its book-copying project, but concluded it is being done in a way that complies with intellectual property laws while enriching society.
"In my view, Google Books provides significant public benefits," Chin wrote. "It advances the progress of the arts and sciences, while maintaining respectful consideration for the rights of authors and other creative individuals, and without adversely impacting the rights of copyright holders."
Paul Aiken, the executive director for the Authors Guild, maintains that Google is exploiting writers.
"Google made unauthorized digital editions of nearly all of the world's valuable copyright-protected literature and profits from displaying those works," Aiken said in a statement vowing to appeal Chin's decision.
In its statement, Google said it was delighted with the decision.
"As we have long said, Google Books is in compliance with copyright law and acts like a card catalog for the digital age giving users the ability to find books to buy or borrow,"' the company said.
Google had previously negotiated a truce as part of a $125 million settlement. But that deal unraveled in 2011 after the U.S. Justice Department and other critics persuaded Chin that the terms of the deal would give the already influential company too much power in the still-developing market for digital books.
After the settlement came apart, the Authors Guild renewed its push to extract even more money from Google for alleged copyright infringement.
Among the plaintiffs was former New York Yankees pitcher Jim Bouton, author of the best-seller "Ball Four."
Google's current collection of more than 20 million books consists mostly of out-of-print titles. It includes material from the New York Public Library, Library of Congress and several major universities. About 90 million to 100 million more books remain to be scanned, based on estimates that Google has previously made in the case.
Because Google only shows snippets from the books in its database, Chin reasoned it would be difficult for anyone to read any of the works in their entirety by repeatedly entering different search requests.
The judge also concluded that Google's digital book aspirations fit the description of a "transformative" purpose that U.S. courts have determined is allowed under copyright law.
"It preserves books, in particular out-of-print and old books that have been forgotten in the bowels of libraries, and it gives them new life," Chin wrote.
