2:23-cv-00712
W.D. Wash.Apr 4, 2024Background
- Immersion Corporation sued Valve Corporation for patent infringement of seven patents related to haptic technology in AR/VR systems and video game controllers.
- Valve moved to stay the litigation pending the Patent Trial and Appeal Board's (PTAB) decisions on its petitions for inter partes review (IPR) of all asserted patents.
- Valve filed seven IPR petitions between January and March 2024, covering all asserted claims, with PTAB institution decisions expected July–October 2024.
- When Valve moved to stay, the case was still at an early stage: limited discovery had occurred, with significant pretrial deadlines ahead.
- Immersion opposed the stay, claiming progress in litigation and potential prejudice, while Valve argued that a stay would simplify proceedings, avoid duplicative effort, and not unduly prejudice Immersion.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Stay simplifies proceedings | IPR may not resolve all issues; some claims will survive | PTAB review could be dispositive, and reduce complexity | Weighs in favor of stay |
| Stage of litigation | Substantial progress already made | Case is early, with much work left before trial | Weighs in favor of stay |
| Undue prejudice to Plaintiff | Delay harms licensing business; longer delay reduces patent value | Not a direct competitor; damages compensate any delay | Weighs in favor of stay |
| Timing of PTAB/Stay (pre-institution) | Valve delayed IPRs for tactical advantage | Strong facts for stay; past PTAB institution on same patents | Pre-institution stay is proper |
