UNITED STATES DISTRICT COURT DISTRICT OF MINNESOTA

Heartland, Inc., File No. 23-cv-150 (ECT/ECW)

Plaintiff and Counter- Defendant,

v. OPINION AND ORDER

Povolny Specialties, Inc., and Design Electric, Inc.,

Defendants and Counter- Claimants.

Lee B. Bennin and Loren L. Hansen, Lathrop GPM LLP, Minneapolis, MN, for Plaintiff and Counter-Defendant Heartland, Inc.

Justice Ericson Lindell, Greenstein Sellers PLLC, Minneapolis, MN, for Defendant and Counter-Claimant Povolny Specialties, Inc.

Rachel Zimmerman Scobie, Merchant & Gould P.C., Minneapolis, MN, and James Warren Beard, Merchant & Gould P.C., Denver, CO, for Defendant and Counter-Claimant Design Electric, Inc.

In this patent-infringement case, Defendants Povolny Specialties and Design Electric seek pre-discovery summary judgment. The at-issue patents concern commercial lighting control technology. Defendants’ basic contention is that the accused lighting control panels—which were manufactured by Povolny and installed by Design Electric— cannot infringe because they do not contain essential claim limitations of the asserted patents, including a “soft start circuit device” or “soft start circuitry coupled with solid state lighting devices within a soft start LED light bank.” Plaintiff Heartland opposes the motion. It argues that a reasonable juror could find infringement and that, regardless, it should have the chance to obtain discovery before the summary-judgment motions are decided. Defendants’ motions will be granted. The evidence Heartland identifies would

not justify a finding of infringement, and Heartland has not shown how the requested discovery (much of which is already available to Heartland) would justify a verdict in its favor. I1

Heartland, a Minnesota-based corporation, is the assignee of two patents related to commercial lighting control technology—U.S. Patent Nos. 9,788,391 B1 and 10,390,400 B1. Compl. [ECF No. 1] ¶¶ 2, 26, 32; Ex. A (the “’391 Patent”) [ECF No. 1-1]; Ex. B (the “’400 Patent”) [ECF No. 1-2]. The named inventor on both patents is Blake Redfield; at times relevant to this case, Mr. Redfield served as Traffic Control Manager for the city of St. Cloud, Minnesota. See ’391 Patent at 1; ’400 Patent at 1; ECF No. 45 ¶ 4. Mr. Redfield

assigned his patent applications to Heartland on May 2, 2016. See ECF No. 21 ¶ 3, Exs. D, E.2

1 Unless otherwise noted, the facts are undisputed or described in a light most favorable to Heartland. Fed. R. Civ. P. 56(a).

2 Design Electric raises a question regarding the assignment’s validity, but not as a ground for summary judgment. See ECF No. 19 at 5 & n.1; see also ECF No. 9 ¶ 48 (asserting Heartland lacks standing to enforce the patents because Mr. Redfield lacked authority to assign rights to the patents). Similarly, though Povolny Specialties challenges the patents’ inventorship, it does not raise this as a ground for summary judgment. See ECF No. 8 at 6, ¶ 5. Povolny is a Minnesota-based electrical and metal fabricator that, among other business activities, manufactures cabinets containing control panels for commercial street lighting. Compl. ¶¶ 3, 17; ECF No. 8 ¶ 3; ECF No. 27 ¶ 6, Ex. D. [ECF No. 27-1 at 38–

40]. Design Electric is a Minnesota-based electrical contractor that, among other activities, installs lighting control panels manufactured by Povolny. Compl. ¶¶ 4, 17; ECF No. 9 ¶ 4; ECF No. 27 ¶ 7, Ex. E [ECF No. 27-2 at 1–5]. The ’391 Patent, entitled “Solid State Lighting Panel,” issued October 10, 2017. The ’391 Patent claims priority to provisional application no. 62/387,967, filed January 11,

2016, and provisional application no. 62/386,494, filed December 3, 2015. ’391 Patent at1. The ’391 Patent is generally directed to industrial and commercial lighting panels capable of “sequentially energizing a plurality of LED lighting panels . . . and ramping up luminous intensity within each panel or group of co-powered panels.” ’391 Patent 1:15– 23. As the ’391 Patent describes, the invention seeks primarily to prevent sudden spikes

of “inrush current” when lighting panels are energized simultaneously—as such spikes are “harmful not only to the panel but also to the upstream power line source and the downstream lighting devices as well.” Id. 1:25–33. The ’391 Patent defines “inrush current” as “a momentary current surge in [the] electrical device occurring when the power control device is first activated,” or the “maximum, instantaneous input current drawn by

an electrical device when [it is] first turned on.” Id. 1:34–37. The ’391 Patent has one independent claim, which states: 1. In combination, a solid state lighting panel and a plurality of soft start LED light banks, comprising: an incoming AC line power connection; a plurality of solid state lighting devices within said plurality of soft start LED light banks; soft start circuitry coupled with and configured to gradually increase the luminous intensity of at least one of said plurality of solid state lighting devices upon an initiation; a plurality of electrical relay devices electrically coupled to said incoming AC line power connection, individual ones of said plurality of electrical relay devices operative to selectively couple and uncouple said incoming AC line power line connection to respective individual ones of said plurality of solid state lighting devices; and a programmable logic circuit in electrical communication with said plurality of electrical relay devices and configured to sequentially energize said individual ones of said plurality of electrical relay devices and thereby selectively couple said incoming AC line power line connection to respective individual ones of said plurality of solid state lighting devices in synchronization with a zero crossing point of the sinusoidal input line voltage, to thereby initiate said at least one of said plurality of solid state lighting devices.

’391 Patent 7:38–62 (emphasis added). The ’400 Patent, entitled “Soft Start Circuitry for LED Lighting Devices with Simultaneous Dimming Capability,” issued August 20, 2019. The ’400 Patent claims priority to provisional application No. 62/386,494, filed December 3, 2015. ’400 Patent at 1. The ’400 Patent is generally directed to “soft start Light Emitting Diode (LED) lighting, and more particularly to retrofitting existing commercially available circuitry to provide enhanced soft start circuitry amenable to energizing LED based lighting devices.” ’400 Patent 1:17–21, 3:33–37. The ’400 Patent has three independent claims, though the Complaint identifies only Claim 1 specifically. See Compl. ¶ 33 (“Defendants’ . . . Infringing Control Panels . . . infringe at least claim 1 of the ’400 Patent.”). Claim 1 states: 1.
