Heartland, Inc. v. Povolny Specialties, Inc.

Background

Heartland, Inc., the assignee of U.S. Patent Nos. 9,788,391 and 10,390,400, sued Povolny Specialties, Inc. and Design Electric, Inc. for patent infringement. The patents concern commercial lighting-control technology, including systems intended to reduce sudden electrical current surges when LED lighting is turned on.

Povolny manufactures cabinets containing commercial street-lighting control panels. Design Electric installs control panels manufactured by Povolny. The companies collaborated on a St. Cloud streetlight retrofit project before the patents issued. Heartland alleged that control panels manufactured and installed after that project were based on Heartland’s design and incorporated technology claimed in the patents.

The defendants sought summary judgment before discovery. Summary judgment is a ruling without a trial when the evidence shows that no reasonable jury could find for the opposing party on a legally necessary issue. The defendants argued that the accused control panels lacked essential elements of both patents’ claims.

The ’391 Patent

Claim 1 of the ’391 Patent requires, among other things, a solid-state lighting panel, multiple soft-start LED light banks, and soft-start circuitry connected to the lighting devices. Povolny attested that its accused cabinets did not include LED lights, other lighting devices, soft-start circuit devices, or other soft-start circuitry. Its wiring diagrams likewise did not show those components.

Design Electric attested that soft-start circuitry was not installed inside any Povolny lighting control panel that it had installed. It also stated that the ’391 Patent’s claims could not be satisfied by the control panel alone because the claims require LED light fixtures containing soft-start circuitry.

The court found that Heartland offered no evidence from which a reasonable juror could conclude that either defendant infringed the ’391 Patent. Heartland did not dispute that Claim 1 required a combination of a lighting control panel and LED light fixtures with soft-start circuitry, and it offered no evidence showing that the accused panels contained that circuitry. The court also rejected Heartland’s argument that claim construction of “soft start circuitry” was necessary because Heartland’s infringement theory did not depend on any particular interpretation of that term.

The ’400 Patent

The asserted claims of the ’400 Patent require a “soft start circuit device” configured to soft-start LED devices. The court found no genuine dispute that the accused control panels did not contain that device. The court also noted that any soft-start devices Design Electric installed were installed in light fixtures and were installed before the ’400 Patent issued.

Heartland did not substantively respond to the defendants’ argument concerning the ’400 Patent’s required soft-start circuit device. The court treated that failure as a waiver of the argument and, independently, concluded on the merits that the accused panels lacked the required device.

Request for More Discovery

Heartland asked the court to delay or deny summary judgment under Federal Rule of Civil Procedure 56(d). That rule can allow additional discovery when a party identifies specific facts it needs, shows that those facts exist, and shows that they are necessary to oppose summary judgment.

The court rejected the request. It found that some requested information, including St. Cloud project specifications, was publicly available; other information was already accessible to Heartland; and Heartland did not explain how the remaining requested information could rebut the evidence that the accused panels lacked the required patent elements.

State-Law Counterclaim and Disposition

Povolny also asserted a state-law counterclaim for tortious interference with prospective economic advantage. After dismissing all federal patent claims, the court declined to exercise supplemental jurisdiction, meaning its authority to hear a related state-law claim. The court stated that the case was still in its earliest stages and that the usual considerations favored leaving the remaining state-law claim to another forum.

The order took the following actions:

- Granted Design Electric, Inc.’s motion for summary judgment. - Granted Povolny Specialties, Inc.’s motion for summary judgment. - Dismissed without prejudice Count III of Povolny Specialties, Inc.’s verified answer and counterclaim. - Dismissed with prejudice Heartland, Inc.’s complaint.

The court ordered that judgment be entered accordingly.
