Federal Circuit Finally Defines Materiality for Inequitable Conduct

After almost 15 years of admittedly dodging the issue, the Court of Appeals for the Federal Circuit in Digital Control Incorporated v. Charles Machine Works, ___ F.3d ___, 2006 WL 288075 (Fed. Cir., Feb. 8, 2006), finally determined that the U.S. Patent and Trademark Office Rule 56, as amended in 1992, does not supplement or replace existing case law in determining the threshold of materiality. The court stated that '[a]lthough we have affirmed findings of materiality based upon the new Rule 56, we have declined to address whether the Rule 56 standard replaced the old 'reasonable examiner' standard.' Id. at *4. Instead, the court found the Rule 56 standard merely 'provides an additional test of materiality' to the existing 'but for,' 'but it may have,' and 'reasonable examiner' tests.

The decision in Digital Control arose from a determination by the district court that the two patents in suit were unenforceable because of inequitable conduct by the inventor during prosecution. In particular, the district court had first granted partial summary judgment to the defendant on the basis that misrepresentations in a Rule 131 affidavit and failure to cite prior art were material. Then, after a bench trial on the issue of intent, the district court determined that the misstatements and omissions were material under the 'reasonable examiner' standard even though the patents were filed and prosecuted after the 1992 amendments to Rule 56. The CAFC, while noting that '[d]etermining at summary judgment that a patent is unenforceable for inequitable conduct is permissible,' reversed the summary judgment as to the materiality of the omission to cite the prior art.
