November 23, 2011 - A company called Personal Audio LLC filed a patent infringement suit against Amazon. Personal Audio recently won a jury verdict of $12 million from Apple in a similar lawsuit.

The lawsuit claims that the act of downloading a "navigable playlist" to Amazon's new tablet PC, the Kindle Fire, infringes two Personal Audio patents.

Personal Audio is also suing Apple again, this time for infringement of its second patent. This past summer, Personal Audio won a jury award of $12 million ($8 million plus $4 million in interest) over Apple's infringement of the first Personal Audio patent. Apple is appealing that verdict.

Both Apple lawsuits and the Amazon lawsuit were filed in the U.S. District Court for the Eastern District of Texas.
