The Alex eReader electronic readers are pictured in this handout released to Reuters November 3, 2009. Spring Design, a maker of electronic readers, is suing Barnes & Noble Inc. , claiming the bookseller's newly launched Nook reader illegally copied its dual-screen design after the two discussed a possible partnership. Spring Design said Barnes & Noble used its proprietary design to better compete with Amazon.com's market-leading Kindle, while failing to disclose its intentions to make its own device. In a lawsuit filed on Monday in U.S. District Court in San Jose, California, Spring Design said it had shared the design of its Alex eReader with Barnes & Noble under protection of a nondisclosure agreement, hoping to strike a deal to bring a device to market.
