In a decision concerning the so-called “25 percent rule” and “the entire market value rule,” the Federal Circuit in the case of Uniloc USA, Inc. et al. v. Microsoft Corp., Nos. 2010-1035, -1055 (Fed. Cir. Jan. 4, 2011), affirmed the U.S. District Court for the District of Rhode Island’s grant of a new trial on damages on the improper use of the entire market value rule. The Rhode Island District Court allowed Uniloc’s damages expert to proffer testimony on the 25 percent rule, which he did in addition to proffering testimony on the entire market value rule. The jury awarded Uniloc damages of $388 million based on the testimony of Uniloc’s damages expert. On appeal, the Federal Circuit reviewed the propriety of the 25 percent rule, the application of the entire market value rule, and the excessiveness of the jury’s damages award.
