    Court Narrows Joby's Claims Against Archer

    The U.S. District Court for the Northern District of California dismissed certain trade-secret and contract-related claims against Archer and an employee, with leave to amend in some cases, while allowing other claims to proceed. The ruling was issued on September 29.

  • Archer's Counterclaims Dismissed Without Leave to Amend

    The court dismissed Archer's counterclaims against Joby Aero and Joby Aviation regarding alleged Lanham Act and California Unfair Competition Law violations, without leave to amend — eliminating Archer's offensive claims.

  • Litigation Overhang on Wisk Acquisition

    The ruling arrives as Archer pursues its acquisition of Boeing's Wisk Aero, SkyGrid, and Insitu; the ongoing litigation with Joby, a direct competitor, adds legal uncertainty to the strategic deal.


Analysis · ACHR · Manufacturing

The court's ruling is a mixed outcome. Archer's exposure is reduced — several trade-secret and contract claims were dismissed, though some may be refiled. The bigger blow is the dismissal of Archer's own counterclaims against Joby without leave to amend, which eliminates Archer's offensive leverage in the dispute. Joby alleged a former employee took confidential information related to business strategies, partnership terms and aircraft specifications before joining Archer, and that Archer misused the trade secrets to undercut one of Joby's agreements with a real-estate developer. Joby sought an unspecified amount of monetary damages and an order preventing Archer from using its trade secrets. This comes amid Archer's pending acquisition of Boeing's Wisk Aero, a deal that could face heightened scrutiny given the ongoing litigation with a direct competitor.
