Summary
The United States Court of Appeals for the Federal Circuit vacated summary judgments concerning inequitable conduct and Walker Process fraud in a patent dispute between Global Tubing LLC and Tenaris entities. The court held that genuine disputes of material fact existed regarding whether Tenaris acted with specific intent to deceive the Patent and Trademark Office and whether the CYMAX documents were material or cumulative prior art. The case was remanded for further proceedings.

Questions Presented
- Whether summary judgment for Global Tubing on inequitable conduct was proper when the evidence permitted competing reasonable inferences about the specific intent to deceive the PTO.
- Whether summary judgment for Global Tubing on inequitable conduct was proper when the evidence permitted competing reasonable inferences about whether the CYMAX Documents were material or cumulative of Chitwood.
- Whether summary judgment for Tenaris on Global Tubing's Walker Process fraud claim was proper when genuine disputes existed concerning fraudulent procurement, the relevant product and geographic markets, dangerous probability of monopolization, and anticompetitive conduct.
- Whether the district court could rely on the Fifth Circuit's limited enhanced-leeway exception to resolve disputed intent and credibility issues at summary judgment.
Holdings
- Summary judgment for Global Tubing was improper because genuine disputes of material fact existed regarding whether Dr. Valdez acted with the specific intent to deceive the PTO.
- Summary judgment for Global Tubing was independently improper because genuine disputes of material fact existed regarding whether the CYMAX Documents were but-for material to patentability or merely cumulative of Chitwood.
- Summary judgment for Tenaris on Global Tubing's Walker Process fraud claim was improper because genuine disputes of material fact existed concerning fraudulent patent procurement, the relevant market, dangerous probability of monopolization, and predatory or anticompetitive conduct.
- The district court could not invoke the Fifth Circuit's limited exception permitting greater leeway in bench-trial summary judgment because the record contained disputed evidentiary facts and witness-credibility issues.
Key quotations
“In doing so now, we conclude there is a genuine dispute as to the material fact of whether the single most reasonable inference is that Dr. Valdez acted with the specific intent to defraud the PTO.” (16)
“Generally, the concerns attendant to awards of summary judgment on inequitable conduct relate to the inherently factual nature of the issue of intent.” (24)
“We are not persuaded that, as a matter of law, Tenaris’ alleged 29% market share is per se too small to create a “dangerous probability” that Tenaris might obtain a monopoly.” (32)
“We remand for further proceedings consistent with this opinion.” (35)
Factual background
Tenaris acquired documents describing Southwestern Pipe's CYMAX quenched-and-tempered coiled tubing and later obtained patents covering Tenaris's BlueCoil product. During prosecution of the patents, Tenaris submitted the Chitwood reference but did not initially submit the full CYMAX Documents, including a page disclosing a carbon range overlapping the claimed range. Global Tubing alleged that the withholding constituted inequitable conduct and that Tenaris sought to monopolize the coiled-tubing market through fraudulently obtained patents. The record contained competing evidence concerning the intent of Tenaris's inventor, the materiality and cumulative nature of the CYMAX Documents, the relevant market, Tenaris's market share, and its alleged intent to enforce the patents against Global Tubing.
Procedural history
Global Tubing filed a declaratory-judgment action concerning infringement of Tenaris's patents, and Tenaris counterclaimed for infringement. Global Tubing later added claims for inequitable conduct and Walker Process fraud. The district court granted Global Tubing summary judgment on inequitable conduct and granted Tenaris summary judgment on the Walker Process claim. The Federal Circuit vacated both summary-judgment rulings and remanded, while affirming the district court's denial of summary judgment to Tenaris on the inequitable-conduct claim.
Remand instructions
Vacate the grant of summary judgment to Global Tubing on inequitable conduct and the grant of summary judgment to Tenaris on the Walker Process fraud claim. Remand for further proceedings consistent with the opinion, including resolution of factual disputes concerning intent, materiality, cumulative prior art, market definition, dangerous probability of monopolization, anticompetitive conduct, and the appropriate market-measurement date. Affirm the denial of summary judgment to Tenaris on no inequitable conduct.
