Joint Infringement of a Method Claim Requires "Direct Control" of Each Step

Client Alert | 1 min read | 07.16.08

In MuniAuction, Inc. v. Thomson Corp. ( No. 2007-1485; July 14, 2008), a Federal Circuit panel vacates an award of $77 million based on a finding that the asserted claims were either obvious or not infringed.

On the question of obviousness, the only difference between the asserted independent claims and the prior art was the use of a web browser interface. Following KSR Int'l Co. v. Teleflex, Inc., 127 S. Ct. 1727 (2007), the Federal Circuit panel easily concludes that modifying the prior art to include a web browser was a predictable solution well within the capabilities of a person of ordinary skill in the art. The district court's finding of non-obviousness is therefore reversed as to the independent claims.

The Federal Circuit concludes that remaining dependent claims are not infringed, thus reversing the district court on this issue as well. Each of the dependent claims required at least two parties to perform all the steps. Joint infringement of a method claim requires one party to exercise "control or direction" over the entire claimed process, such that every step is attributable to the controlling party or "mastermind." In the case at hand, the evidence showed that the defendant, Thomson, did not direct another party to perform any steps on its behalf, and thus joint infringement was not proven. Joint infringement requires more than an awareness of another party's actions.

A Sign of What’s to Come? Court Dismisses FCA Retaliation Complaint Based on Alleged Discriminatory Use of Federal Funding

On November 7, 2025, in Thornton v. National Academy of Sciences, No. 25-cv-2155, 2025 WL 3123732 (D.D.C. Nov. 7, 2025), the District Court for the District of Columbia dismissed a False Claims Act (FCA) retaliation complaint on the basis that the plaintiff’s allegations that he was fired after blowing the whistle on purported illegally discriminatory use of federal funding was not sufficient to support his FCA claim. This case appears to be one of the first filed, and subsequently dismissed, following Deputy Attorney General Todd Blanche’s announcement of the creation of the Civil Rights Fraud Initiative on May 19, 2025, which “strongly encourages” private individuals to file lawsuits under the FCA relating to purportedly discriminatory and illegal use of federal funding for diversity, equity, and inclusion (DEI) initiatives in violation of Executive Order 14173, Ending Illegal Discrimination and Restoring Merit-Based Opportunity (Jan. 21, 2025). In this case, the court dismissed the FCA retaliation claim and rejected the argument that an organization could violate the FCA merely by “engaging in discriminatory conduct while conducting a federally funded study.” The analysis in Thornton could be a sign of how forthcoming arguments of retaliation based on reporting allegedly fraudulent DEI activity will be analyzed in the future....
