AMS SENSORS USA INC. f/k/a § TEXAS ADVANCED OPTOELECTRONIC § SOLUTIONS, INC. § Civil Action No. 4:08-cv-00451 § Judge Mazzant v. § § RENESAS ELECTRONICS AMERICA § I NC. f/k/a INTERSIL CORPORATION §

MEMORANDUM OPINION AND ORDER Pending before the Court is Defendant’s Motion to Strike Plaintiff’s Election of Remedies (Dkt. #843). Having considered the Motion and the relevant briefing, the Court finds the Motion should be GRANTED in part and DENIED in part. BACKGROUND I. The First Trial The parties develop and sell ambient light sensors, which are used in electronic devices to adjust screen brightness in response to incident light. In the summer of 2004, the parties confidentially shared technical and financial information during negotiations for a potential acquisition.1 In August 2004, the parties went their separate ways. Soon after, Defendant Renesas Electronics America Inc. f/k/a Intersil Corporation (“Renesas” f/k/a “Intersil”) released new sensors with the technical design Plaintiff AMS Sensors USA Inc. f/k/a Texas Advanced Optoelectronic Solutions, Inc. (“AMS” f/k/a “TAOS”) disclosed in the confidential negotiations. In January 2005, Plaintiff won a contract from Apple for the first-

In February 2005, Plaintiff released its product that contained the confidential technology. In January 2006, Defendant reverse-engineered that product. In March 2008, Defendant won a contract from Apple for the second-generation iPhone. On November 25, 2008, Plaintiff sued for patent infringement, breach of contract, trade

secret misappropriation, and tortious interference with prospective business relations (Dkt. #1). The trade secret claim asserted one technical trade secret and two financial trade secrets. After a trial in early 2015, a jury returned a verdict for Plaintiff and awarded damages on all four claims. The Court ruled on the parties’ post-trial motions and entered final judgment. Both parties appealed. II. The Federal Circuit Mandate The Federal Circuit wrote a lengthy opinion, affirming in part, reversing in part, vacating in part, and remanding the case (Dkt. #614). Among its rulings, the Federal Circuit affirmed liability for trade secret misappropriation, but only on the technical trade secret. It identified the single “asserted trade secret” (“ATS”) as “a structure that includes both a 1:1 ratio of shielded to

unshielded wells and interleaving of the wells in that ratio, i.e., repetition of the 1:1 ratio in an alternating pattern (requiring more than one set of wells).” Tex. Advanced Optoelectronic Sols., Inc. v. Renesas Elecs. Am., Inc., 895 F.3d 1304, 1313 (Fed. Cir. 2018) (hereinafter “TAOS”) (emphasis original). Liability for the two financial trade secrets was vacated. The misappropriation damages were overturned for two independent reasons: (1) Plaintiff’s expert “did not explain which of the trade secrets contributed to what amount of profit to be disgorged” and (2) the ATS “was accessible to Intersil by proper means long before the time of many of the sales included in TAOS’s request for monetary relief.” Id. at 1317. The Federal Circuit further explained the second reason: Such accessibility existed no later than January 2006, when Intersil successfully reverse- engineered the TSL2560, and perhaps as early as February 2005, when TAOS ‘released’ the TSL2560. . .

. . . Secrecy protection terminated at the end of the period of time it would have taken Intersil, after Intersil’s permissible discovery of the photodiode structure, to recreate that structure in its own products. . .

. . . That limited head-start period, which ‘depend[s] upon the facts of each case,’ ends TAOS’s entitlement to monetary relief.

Here, the jury awarded disgorgement of profits in the exact amount TAOS’s expert proposed, based on sales from April 2006 through March 2014. . . TAOS’s evidence supporting its claim to monetary relief for trade secret misappropriation did not limit the covered sales to a head-start period, and that omission cannot be deemed harmless. Id. at 1317-18. The Federal Circuit concluded: “On remand, any determination of sales-based monetary relief for trade secret misappropriation requires evidence and a determination of the time at which the trade secret became properly accessible to Intersil and the duration of any head-start period.” Id. at 1318. The Federal Circuit discussed additional errors with Plaintiff’s disgorgement award. In trade secret cases, plaintiffs sometimes use the defendants’ gains as evidence of the plaintiffs’ losses, or of the reasonable royalty. But here, Plaintiff sought disgorgement of Defendant’s profits without “any evidence or arguments that such profits soundly measured . . . TAOS’s losses or a reasonable royalty.” Id. at 1320. Defendant’s profits were therefore not “a case-specific proxy for, TAOS’s losses or a reasonable royalty.” Id. There was “no evidence” that Defendant’s profits from misappropriating Plaintiff’s trade secret correlated with Plaintiff’s losses. Id. at 1321. “For example, . . . TAOS has not identified evidence showing that it would have won the [Apple] contract had Intersil not used TAOS’s photodiode array structure.” Id. Finally, the Federal Circuit found that the patent infringement award was duplicative of the trade secret misappropriation award. Id. at 1328. The patent infringement award was based on the sale of four products. Id. The misappropriation award was based on the sales of these same four products, as well as ten more. Id. The patent infringement award “was therefore duplicative of some portion of the disgorgement award for trade secret misappropriation, to the extent the awards cover the same period.” Id. In other words, the patent award “covers sales . . . that are already part of the disgorgement award. Such overlap is improper.” Id. at 1329.

III. On Remand On remand, the parties dispute damages. On August 9, 2019, Judge Schell2 transferred this case to the undersigned (Dkt. #662). On November 25, 2019, Plaintiff moved for Entry of Final Judgment (Dkt. #672). The Court denied the motion on March 27, 2020 (Dkt. #682). Relevantly, the Court concluded Plaintiff’s tortious interference claim was eliminated on appeal (Dkt. #682 at p. 22). The Federal Circuit found there was no causation between Defendant’s trade secret misappropriation and its subsequent iPhone contract (Dkt. #682 at p. 22, n.11). This Court was unequivocal: In light of the Federal Circuit’s discussion . . ., there is no evidence to support any link between these underlying acts and Apple’s decision to purchase Renesas’s ambient light sensors for the iPhone 3G in 2008. . . . Renesas’s other two arguments can be boiled down to one concept: Renesas did not win the Apple iPhone 3G contract using any misappropriated information or by using TAOS’s patent subject matter; rather, as the Federal Circuit summarized the evidence at trial, Renesas won the contract “primarily” due to Renesas’s “significantly lower bid price, made possible by using the (lower cost) plastic packaging.” . . . The Court must agree. . . . Although the Federal Circuit’s discussion was not directed at TAOS’s tortious interference claim, the Court struggles to see how it is not the law of the case.
