Hong Kong uCloudlink Network Technology Limited v. SIMO Holdings Inc.

Background

The case began as a patent-infringement lawsuit by uCloudlink entities against SIMO entities. SIMO Holdings Inc., Skyroam, Inc., and Shenzhen Skyroam Technology Co., Ltd. later asserted counterclaims against Hong Kong uCloudlink Network Technology Limited and uCloudlink (America) Ltd. for trade-secret misappropriation. The pending motion concerned the fifth and sixth causes of action: one under the federal Defend Trade Secrets Act and one under the California Trade Secrets Act.

The operative pleading was the second amended counterclaims. The counterclaimants alleged that Skyroam owned trade secrets concerning virtual-SIM technology, including methods for allocating virtual SIMs, managing communications and carrier re-authentication, designing upgrade protocols, and operating a backend billing system. They alleged that Wang Bin learned these secrets while working for Skyroam Shenzhen, copied some to a USB drive and personal computer, then joined a uCloudlink entity and transferred the information to a uCloudlink work computer.

The counterclaimants further alleged that a Chinese patent application and other uCloudlink patent applications disclosed or incorporated Skyroam’s trade-secret information. They claimed that Wang Bin and Gao Wen, along with other uCloudlink founders, had planned for Wang Bin to work at Skyroam, obtain its trade secrets, and bring them to uCloudlink. The second amended counterclaims abandoned an alternative theory that uCloudlink learned of the alleged misappropriation only after Wang Bin’s 2018 deposition and then continued selling products embodying the information.

Legal standard

The court applied Federal Rule of Civil Procedure 12(b)(6), which permits dismissal when a pleading does not state a legally sufficient claim. Under the plausibility standard, a pleading must allege enough underlying facts to support a reasonable inference of liability; allegations that are merely consistent with liability are not enough. The court generally accepts factual allegations as true and views them favorably to the party opposing dismissal, but it need not accept unsupported conclusory statements.

Analysis

The court held that the new allegations, together with the earlier allegations, still did not plausibly support the claimed conspiracy. Most allegations showed conduct consistent with a conspiracy but did not establish that an agreement existed at the outset, when Wang Bin left Skyroam and later joined uCloudlink. The allegation that Gao Wen directed Wang Bin to leave Huawei and join Skyroam was conclusory because the counterclaims supplied no specific facts supporting it. The court also found the timing of that alleged direction questionable because Gao Wen had left Huawei two years earlier.

Because the conspiracy theory was not plausibly pleaded, the court did not decide other issues, including whether uCloudlink America was part of a conspiracy, whether certain uCloudlink entities could be liable under a single-business-enterprise theory, or whether the federal trade-secret statute could apply outside the United States.

At the hearing, the counterclaimants proposed a different theory: that a conspiracy formed no earlier than an October 23, 2015 patent-evaluation conference, after Wang Bin had already joined uCloudlink. The court found that theory was not pleaded in the second amended counterclaims. It also denied leave to assert the theory in a third amended pleading because the counterclaimants had already received an opportunity to correct the conspiracy allegations and had chosen to rely only on the earlier theory.

Disposition

The court granted the counterdefendants’ motion to dismiss the trade-secret misappropriation counterclaims. The dismissal was with prejudice, and the counterclaimants did not receive leave to amend. The order disposed of Docket No. 75.
