Home Diagnostics Inc. (now Nipro Diagnostics) is one of the largest cobranders of blood glucose products for diabetics and offers low-cost alternatives to products offered by competitors. After a three-year battle with Roche, the district court granted a summary judgment of noninfringement in favor of HDI, concluding that no reasonable juror could find that HDI products infringed Roche’s patent relating to blood glucose monitors. The first phase of the case had concluded successfully for HDI when the court ruled, following a bench trial, that Roche’s other patent-in-suit had been obtained by inequitable conduct and is unenforceable.
