Massive Patent Verdict Overturned
By Jia Ryu – Edited by Stephanie Young
Uniloc v. Microsoft, No. 03-440 S (D. R.I. Sept. 29, 2009)
Opinion
The United States District Court for the District of Rhode Island vacated one of the largest patent verdicts in history, in which a jury held that Microsoft’s “Product Activation System” (“PA”) infringed on Uniloc’s patented “System for Software Registration” (the “‘216 patent”). In holding that Microsoft did not infringe as a matter of law, the District Court found that Uniloc had not shown the presence of each element of the patent claim or its substantial equivalent in the accused device as required by Lemelson v. United States, 752 F.2d 1538 (Fed. Cir. 1985). The Court, while noting that the jury’s finding deserved deference, expressed its “firm belief” that the jury failed to grasp the complex issues in the case and lacked a legally sufficient basis for the finding.
