U.S. District Court for the Illinois Central District Court

Court Profile: U.S. District Court for the Central District of Illinois

Court Overview
The U.S. District Court for the Central District of Illinois (C.D. Ill.) is a federal trial court within the Seventh Circuit. Appeals from this court are heard by the U.S. Court of Appeals for the Federal Circuit for patent cases and the Seventh Circuit for other matters. The district operates out of courthouses in Peoria, Springfield, Urbana, and Rock Island, serving 46 counties in the central region of Illinois. Historically, the Central District of Illinois has not been one of the nation's top venues for patent litigation and maintains a relatively small active patent docket compared to districts like the Western District of Texas or the District of Delaware.

Patent Docket Reputation
The Central District of Illinois is not considered a "rocket docket" for patent cases, nor has it cultivated a specific reputation as a plaintiff-friendly venue. An older analysis of cases by LegalMetric indicated an average time to termination of 13.4 months for all patent cases and 17.6 months for cases resolved on the merits. The same report found a 33% win rate for patent holders in the few cases that reached trial. A 2010 analysis noted that the district's judges had a high reversal rate on claim construction rulings at the Federal Circuit compared to other popular patent venues at the time, though more recent statistics on this metric are not readily available.

Local Rules and Procedures
The Central District of Illinois has not adopted a specialized set of local patent rules similar to those found in districts with heavier patent dockets, such as the Northern District of Illinois or the Eastern District of Texas. Patent litigation proceeds under the court's standard Local Civil Rules, which govern aspects like filing formats, motions, and discovery. For guidance on jury instructions in patent cases, the court's website directs attorneys to the Seventh Circuit's Pattern Civil Jury Instructions, which include a section dedicated to patent law. This lack of specific patent rules can lead to more case-by-case management of scheduling and discovery milestones.

Notable Cases and Rulings
The court has handled a number of patent infringement cases, though few have garnered national attention. The district's tracked case, Portus Singapore Pte Ltd. v. Zmodo Technology (1:19-cv-01157), filed in 2019, is representative of the infringement disputes on its docket. The defendant in that case, Zmodo Technology, has been named in several other patent infringement lawsuits within the district. The court was also the forum for a dispute in Cummins, Inc. v. TAS Distributing Company, Inc., a case where the Federal Circuit in 2012 affirmed the district court's decision that patent invalidity and unenforceability defenses were precluded by res judicata from an earlier contract action.

Judges
The court currently has four active Article III judges: Chief Judge Colin S. Bruce, Judge Sue E. Myerscough, Judge Colleen R. Lawless, and Judge Jonathan E. Hawley. Judge Hawley was confirmed in late 2024, and Judge Lawless was confirmed in 2023, placing them on the bench after the sample tracked case was closed. The tracked case from 2019 was assigned to then-Chief Judge James E. Shadid, who has since taken senior status.
