National Brake & Electric Co. v. Christensen

Background

Christensen and the Allis‑Chalmers Company sued the National Brake & Electric Company in the Eastern District of Wisconsin for infringing a patent numbered 635,280. The complaint alleged that an earlier patent numbered 621,324 had been issued, returned to the Patent Office for defects, and then replaced by the later patent. The Wisconsin District Court ruled for Christensen, the Seventh Circuit affirmed, and the case returned for an accounting. Christensen later sued another company in the Western District of Pennsylvania, and that litigation produced a judgment that led to dismissal of the claim against patent 635,280 and later dismissal of the claim on patent 621,324 for want of prosecution.

Reasoning

The central question was whether the Pennsylvania judgment could be used to stop the ongoing Wisconsin proceedings. The defendant asked the Seventh Circuit to treat the Pennsylvania decree as a bar to further action in Wisconsin. The Supreme Court explained that the proper route is for the appellate court to treat such an application as a request for leave to file in the trial court a petition in the nature of a bill of review — in plain terms, a request to reopen or reconsider the case because of the later judgment — and to decide that request in its discretion based on materiality and diligence. The Court reversed the Seventh Circuit’s refusal to entertain the petition and remanded for appropriate consideration.

Real world impact

The decision clarifies procedure when a party obtains a later judgment in another court and seeks to use it to end an earlier suit: an appeals court should consider allowing a new petition in the trial court to raise the later judgment as a bar. The Supreme Court remanded for that process and did not decide the underlying patent validity issues.
