Sins of omission – Inequitable conduct case turns on undisclosed information


SKU: IIPjj143. Category: .


Abstract: So-called “inequitable conduct” during the patent application process can undermine the enforceability of that patent. But bad information isn’t always the problem; “sins of omission” can come back to haunt applicants as well. This article discusses an infringement case in which the defendant supported its arguments with testimony from an executive from another company. When it was later discovered that the plaintiff had withheld evidence that corroborated that testimony, the appellate court sent the case back to the district court to determine whether the plaintiff’s withholding was material, as well as whether it acted with the intent to deceive the U.S. Patent and Trademark Office. The Ohio Willow Wood Co. v. Alps South, LLC, Nos. 2012-1642, 2013-1024, Nov. 15, 2013 (Fed. Cir.)
