I. SUMMARY OF FACTS

Tigo and SMA America are Delaware corporations that compete in the industry of solar technology. D.I. 16, {§ 1-2. SMA America is a wholly owned subsidiary of SMA America Holdings, LLC, which in turn is a subsidiary of SMA AG. /d.,§ 9. On July 11, 2022, Tigo filed several claims of infringement against both SMA America and SMA AG (collectively, “Defendants” or “SMA”), alleging that SMA manufactured and sold rapid shutdown technology that infringed several of Tigo’s patents. Jd. The patents asserted by Tigo include U.S. Patent Nos. 8,823,218 (the “’218 patent”), 8,933,321 (the “321 patent”), 9,584,021 (the “’021 patent”), 9,966,848 (the “’848 patent”), 10,256,770 (the “’770 patent”), and 10,333,405 (the “’405 patent”)

ry

(collectively, the “Asserted Patents”).! Jd, §{ 19-25. In response, SMA argues, among other things, that Tigo is barred from seeking relief for any alleged acts of infringement. D.I. 20, § 158.

According to SMA, Tigo joined the SunSpec Alliance (“SunSpec”), an industry group of solar and energy industry participants, in 2009. Jd, | 160. SMA, who was also a member of SunSpec, contends that the group was “formed to . . . expand the market for renewable power” and encourage cooperation and information-sharing between its members. /d., J 159. As part of joining the group, SMA contends that each member, including SMA and Tigo, was required to execute SunSpec’s written membership agreement (hereinafter, the “SunSpec Member Agreement” or the “Agreement”’). Jd., § 161. Once members, the parties could access and adopt specifications and similar protocols created by SunSpec to enable members to ““plug and play’ system operability of solar power technologies, thereby reducing cost, promising technology innovation, and accelerating industry growth.” Id.

The SunSpec Member Agreement, in turn, imposed several obligations on the members. In creating its specifications, for instance, SunSpec required each member to disclose any of the member’s claims, patents, or patent applications that would be necessary to practice a proposed or adopted SunSpec specification (“Necessary Claims”). Jd., 9] 161-62. Once members disclosed their respective Necessary Claims, the SunSpec Member Agreement required each member to negotiate licenses for its “Necessary Claims” with any other member who showed an interest in adopting their technology. Jd. SMA alleges that, “[a]t a bare minimum,” the Agreement required

1 The Asserted Patents can be divided into two groups: the ’218, ’321, and ’770 patents, which are directed to “[s]ystems and methods for an enhanced watchdog [signal] in solar installations,” are hereinafter known as “Watchdog Signal Patents” and the ’021, °848, and °405 patents, which are directed to an “auxiliary power supply,” are the “Power Supply Patents.”

members “to negotiate in good faith for the grant to each other Member a RAND License to any Necessary Claims.” Jd., J 161.

According to SMA, in September 2017, SunSpec adopted a specification known as the “Communication Signal for Rapid Shutdown SunSpec Interoperability Specification” (“Rapid Shutdown Specification”). Jd, § 163. SMA contends that Tigo was actively involved in SunSpec’s development of the Rapid Shutdown Specification by 2016 and, in December 2017, Tigo submitted claims from its patented technology as “Necessary Claims.” Id., {J 164-65.

SMA alleges that Tigo’s membership in SunSpec coupled with Tigo’s role in the development of the Rapid Shutdown Specification led SMA and other SunSpec members to believe that Tigo consented to their use of Tigo’s patented technology. Jd., 167. According to SMA, many SunSpec members assumed that Tigo did not intend to initiate litigation against any member that used Tigo’s technology in adopting the Rapid Shutdown Specification. Id, □ 168. SMA claims that these expectations were fueled in part by Tigo’s continued attempts to encourage industry players to adopt the Rapid Shutdown Specification. Jd, J] 168-69. According to SMA, Tigo was aware that several SunSpec members, included SMA, intended to do so. Jd. { 168.

Yet, SMA contends that, for nearly two years, Tigo never asserted its patents against other SunSpec members. /d., | 172. Then, in December 2019, SMA contends that Tigo began to dispute that it was not a member of SunSpec. /d., 172-73. According to SMA, around that same time, Tigo threatened some SunSpec members with potential patent litigation. Jd. Finally, without any warning and without attempting to initiate license negotiations with SMA, SMA contends that Tigo filed suit before this Court on June 17, 2022, accusing SMA of infringing its patents. Id., 9] 174-75.

On October 14, 2022, SMA America filed its Answer and Complaint, D.I. 20, asserting that:

Tigo willfully misled SunSpec Alliance members to believe that the Rapid Shutdown Specification was noninfringing and encouraged adoption of the technologies in the Rapid Shutdown Specification, knowing that it did not intend to uphold its obligations in the SunSpec Member[] Agreement and/or the representations and promises it made to the SunSpec Alliance and its members, so that it could subsequently assert infringement and extract licenses, monetary damages, seek an injunction, and/or establish a dominant market share by excluding, reducing, or delaying entry of competitive threats in the market for Rapid Shutdown Specification compliant systems, such as SMA America. Id.,4 178. SMA America filed several counterclaims against Tigo, including claims for: (1) breach of the SunSpec Member Agreement, (2) promissory estoppel; (3) declaration judgment under the doctrine of waiver; (4) declaration judgment by waiver; (5) tortious interference with business relations, (6) unfair competition; (7) false advertising; (8) violation of the Delaware Deceptive Trade Practices Act (DTPA), and (9) trade libel. SMA America also asserted affirmative defenses to Tigo’s claims of infringement under “the doctrine of equitable estoppel, waiver, acquiescence, implied license, patent misuse, and unclean hands.” /d., 4 158. On November 13, 2023, SMA AG filed its Answer and Affirmative Defenses to Tigo’s First Amended Complaint, D.I.
