"Ten years ago, Amazon.com riled the tech world when it sued Barnes & Noble with a patent on "1-click" buying. Critics cried that clicking once to order a book wasn't really an invention — and certainly not worthy of a patent. And it became the poster child for a patent system gone overboard. Now, Amazon is defending itself against Cordance Corp., a company that claims it filed for its patent on 1-click ordering before Amazon's application. The case, filed in 2006, is set for trial on Aug. 3 in Delaware — and Fenwick & West's Lynn Pasahow, the Palo Alto, Calif.-based lawyer who worked to enforce Amazon's 1-click patent, will now play defense for the online bookseller."
