In September, Corydoras Technologies, LLC filed suit in the Eastern District of Texas against retailer Best Buy (2:19-cv-00304) over the sale of a variety of accused products made by others; this past week one of those manufacturers, Amazon (1:19-cv-01095), has asked the Western District of Texas for declaratory judgments of noninfringement of its Fire series tablets, including the Fire HD 10, Fire HD 8, and Fire 7. The patents mentioned in both complaints broadly concern various aspects of a mobile communication device that displays a mirror image of an object taken from a camera facing the direction of the display.
