Elite Semiconductor, Inc. v. Anchor Semiconductor, Inc.

Background

Elite Semiconductor, Inc. filed this action on September 30, 2020. Its second amended complaint asserted two trade-secret misappropriation claims: one under the federal Defend Trade Secrets Act and one under the California Uniform Trade Secrets Act. The complaint focused on Anchor’s HPA product, alleging that it came to market with technology copied from Elite.

After the action began, KLA Corporation acquired Anchor. Anchor disclosed KLA in an updated certificate of interested entities on July 12, 2021. That same day, Elite stated in a joint case-management filing that it did not expect additional parties to be added. The Court then set October 11, 2021, as the deadline to join additional parties.

On September 21, 2021, Elite served document requests concerning the acquisition and Anchor’s corporate structure after the acquisition. On October 27, 2021—after the deadline—Elite said it intended to substitute KLA for Anchor based on an apparent representation that Anchor had been absorbed by KLA. Defendants responded that Anchor remained a separate entity. Elite did not pursue the issue further until January 2023.

Motion and Legal Standards

On March 3, 2023, Elite moved under Federal Rule of Civil Procedure 15(d) for permission to file a supplemental pleading. The proposed pleading would add KLA as a defendant and assert three trade-secret claims alleging that KLA used misappropriated technology in products it purchased or incorporated into new and existing KLA products.

Because the motion came after the Rule 16 scheduling-order deadline, the Court first required Elite to show “good cause” to modify that deadline. The good-cause inquiry primarily examines the requesting party’s diligence. Only if good cause is shown does the court consider whether amendment is proper under Rule 15. Rule 15’s factors include bad faith, undue delay, prejudice, and whether the proposed amendment would be futile.

Court’s Analysis

The Court found that Elite had not acted diligently in three respects. First, Elite knew about KLA’s existence and relationship to Anchor when it helped prepare the case-management order but did not request more time to add parties. Second, Elite did not explain why it could not meet the October 11 deadline. Its September 21 discovery requests were served less than three weeks before the deadline and would not have produced responses until afterward. The Court also noted that Elite had waited until the last three weeks before the deadline to seek information about Anchor’s post-acquisition structure.

Third, Elite did not ask to extend the deadline when it served the discovery requests or when it expressed its intent to substitute KLA after the deadline had expired. The Court rejected Elite’s reliance on information obtained at a January 13, 2023 deposition because that information did not explain why Elite had failed to seek an earlier extension. The Court also noted that Elite waited more than a year after its October 2021 communications before pursuing the issue again.

The Court separately found that the proposed pleading would prejudice Defendants. Discovery had largely focused on Anchor’s HPA product, while Elite’s proposed claims would bring all new and existing KLA products into the case. The Court concluded that this would dramatically expand the litigation after nearly two years of narrower discovery and would entitle Defendants to discovery needed to establish defenses to the new claims.

Disposition

The Court held that Elite failed to show good cause to file the supplemental pleading. Because Elite did not satisfy Rule 16, the Court did not need to decide whether the proposed pleading would otherwise be allowed under Rule 15. Judge Edward J. Davila therefore denied Elite’s motion for leave to file the supplemental pleading. The conclusion states that Plaintiff’s motion was denied.
