Inequitable Conduct Renders ’993 Patent Unenforceable

In Energy Heating v. 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.

Federal Circuit says inequitable conduct can be inferred from activities in a later patent litigation?

Although the patent prosecution process is adversarial in nature, patent practitioners must be keenly aware of their duty to maintain the integrity of any subsequently issued patent by supplying the patent examiner with all prior art that is believed to be relevant and also avoiding any misrepresentations of the prior art.  Patent litigators have long been aware of the potential pitfall of having a patent invalidated based on inequitable conduct due to activities of a patent prosecutor carried out months or years prior to the litigation proceedings.  In light of a recent decision by the Federal Circuit in Regeneron Pharmaceuticals v. Merus, however, it now appears that inequitable conduct by a patent prosecutor may be inferred due to activities of a patent litigator carried out month or years after patent prosecution has concluded.

Federal Circuit says Secondary Considerations Not Part of Prima Facie Obviousness Analysis

Objective indicia must be evaluated before drawing an ultimate conclusion on obviousness, but are not necessarily part of a prima facie “motivation-to-combine” analysis. To prove inequitable conduct based on failure to correct a misrepresentation, the moving party must show actual knowledge of a material misrepresentation and a deliberate failure to inform the PTO with an intent to deceive.

Federal Circuit declares Regeneron patent unenforceable due to inequitable conduct

The Federal Circuit issued a decision in Regeneron Pharmaceuticals, Inc. v. Merus N.V. upholding the determination that the patent owned by biotech firm Regeneron was unenforceable. The decision affirmed a lower court’s finding based on Regeneron’s inequitable conduct during prosecution of the patent at the U.S. Patent and Trademark Office (USPTO), which was the result of the withholding of references from the USPTO that had but-for materiality. The patent, which the Federal Circuit deemed unenforceable, is U.S. Patent No. 8502018, titled Methods of Modifying Eukaryotic Cells.

CAFC reverses Summary Judgment on inherent anticipation, affirms no Inequitable Conduct

It is inappropriate for a trial court to discount material expert testimony so as to weigh the evidence in favor of a party seeking summary judgment. The presence of a genuine dispute precludes summary judgment in such cases. … Failure to disclose arguments concerning claims of a different scope in a different patent application was not inequitable conduct when differences were apparent to the Examiner.
