Sonos v. D&M Holdings (December 8, 2017)

Judge Bryson in the District of Delaware excluded an expert opinion not once, but twice, over violation of the entire market value rule.  Heavily citing to LaserDynamics and Uniloc, Judge Bryson notes that no matter what apportionment is performed, if the royalty base includes more than the SSPU, then the analysis is fatally flawed.
