Last week Amazon (3:19-cv-07474) filed a complaint against Sonohm Licensing LLC, an entity associated with monetization firm IP Edge LLC, seeking declaratory judgments of noninfringement as to its Fire series tablets. Sonohm Licensing sued Best Buy (among others) in August in the District of Delaware, targeting a wide range of products by various manufacturers with three former Siemens patents, specifically alleging infringement of two of those patents through the sale of Amazon Fire series tablets. Amazon pleads that it filed its case directly against Sonohm Licensing to prevent the NPE from securing “in terrorem settlements from retailers who decide they are ill-equipped to defend an unfamiliar technology and do not want their business relationships disrupted”.
