Handing a win to Amazon.com Inc. and its lawyers at Jenner & Block, a judge on Monday tossed a patent lawsuit alleging that the charger sold with Amazon’s Kindle e-reader is identical to one sold by a small company called VoltStar Technologies Inc.
The ruling by U.S. District Judge John Lee in Chicago dismisses design patent infringement claims that VoltStar brought against Amazon last year. Giving little weight to an expert report proffered by VoltStar, Lee ruled that “a side-by-side comparison would yield the conclusion that the two products create a substantially different visual impression.” (You can compare the two chargers on pages six and seven of Lee’s decision.)
