Summary
Roche sued Promega for infringement of US 4,889,818 and breach of the Cetus–Promega license agreement covering Roche's PCR process patents. The district court found the '818 patent unenforceable for inequitable conduct; the Federal Circuit vacated in part and remanded, and on remand the district court again held the patent unenforceable.
