Heat On-The-Fly, the court did not abuse its discretion in finding clear and convincing evidence that the inventor knew that the prior uses were material and specifically intended to deceive the PTO by not disclosing them. The court had sufficient evidence – including evidence of 61 commercial sales dating back to 2006 and no contemporaneous evidence of experimentation – to disbelieve Mr. Hefley’s testimony to the contrary.
