NCLC urges Supreme Court to address state sovereign immunity in patent cases

February 22, 2008

NCLC urged the Supreme Court to consider whether a state waives its claim to sovereign immunity in patent infringement cases if the state itself has filed numerous patent infringement cases in federal court. In its brief, NCLC noted the incongruity between permitting a state to invoke the federal forum repeatedly to protect its patents but resisting the federal forum when accused of patent infringement. NCLC made clear that prior Supreme Court precedent should not upset the careful balance set by Congress in patent litigation when states repeatedly make use of federal courts to assert their rights in other patent infringement cases.
