Streck, Inc. v. Research & Diagnostic Sys., Inc., No. 11-1044 (Fed. Cir. 2012)
Annotate this CaseHematology controls are used to monitor and test the accuracy and consistency of hematology analyzers, which clinical laboratories use to analyze patient blood samples by measuring components of whole blood. Plaintiff and defendant manufacture and sell hematology control products. In 1999, plaintiff filed a patent application directed to an integrated reticulocyte control; about two months later, defendant filed its application. In 2003, after some of plaintiff's patents issued, defendant copied claims from those patents into its pending application and asked the PTO to declare an interference to determine priority of invention. While the request was pending, defendant began manufacturing and selling integrated hematology controls. Plaintiff filed an infringement suit. The district court dismissed invalidity counterclaims with respect to claims plaintiff did not include in its infringement allegations; ruled in favor of plaintiff on enablement; and issued an injunction in favor of plaintiff. The Federal Circuit affirmed. The district court properly refused to address the validity of unasserted claims and correctly denied written description and enablement defenses as a matter of law.
