Executive Summary

A federal district court issued a case management order in Arcturus's trade secret litigation against AbbVie/Capstan, resolving disputes over the protective order and privilege logs. The court allowed Arcturus's Chief Legal Officer to access confidential materials but denied CEO Joseph Payne access to 'CONFIDENTIAL' information, a routine procedural ruling with no financial impact.

Key Facts

  • Ruling is a case management order resolving protective order and privilege log disputes — not a merits ruling on trade secret claims.
  • Court allowed Arcturus CLO Lance Kurata to access both 'CONFIDENTIAL' and 'CONFIDENTIAL – FOR COUNSEL ONLY' materials.
  • Court denied CEO Joseph Payne access to 'CONFIDENTIAL' materials; CFO and CBO were granted access.
  • Parties ordered to use categorical privilege logs; metadata logs not required at this stage.
  • No damages awarded, no injunction issued, no liability determination — purely procedural.

Financial Impact

No financial impact — ruling is procedural with no monetary award or business restriction.

Risk Factors

  • Trade secret case remains pending — adverse final ruling could impact LNP technology ownership.
  • CEO's exclusion from confidential discovery materials may marginally complicate litigation strategy.
