Canvs Corporation v. United States
118 Fed. Cl. 587
Fed. Cl.2014Background
- CANVS sued the United States under 28 U.S.C. § 1498(a) alleging infringement of U.S. Patent No. 6,911,652 (low-light imaging); defendant denied infringement and pleaded invalidity.
- The court granted partial summary judgment invalidating five of seven claims (claims 1–3, 6–7); claims 4 and 5 remain for trial scheduled Dec. 2015.
- Third-party FLIR filed an inter partes review (IPR) petition at the PTO challenging all seven claims; PTO decision whether to institute IPR was pending.
- The government moved to stay this litigation pending resolution of FLIR’s IPR petition; CANVS opposed the stay as premature and prejudicial.
- The court considered traditional stay factors (impact of IPR on litigation, stage of litigation, prejudice/tactical disadvantage) and noted defendant is not the IPR petitioner and is not estopped by the IPR.
- Court denied the motion without prejudice, permitting renewal within 20 days if PTAB institutes review, and instructed the government to address estoppel and changed circumstances in any refiled motion.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Whether to stay the case pending a third-party IPR petition | Stay is premature and would unfairly prejudice CANVS; IPR unlikely to cancel remaining claims 4–5 | Stay appropriate because IPR likely to be instituted and would simplify or moot litigation and conserve resources | Denied without prejudice; motion premature and lack of estoppel weighs against stay |
| Weight of PTO institution uncertainty when deciding stay | PTO may deny institution; uncertainty counsels against stay | PTO institution likely (high grant rates); stronger case for stay if instituted | Court refused to speculate; prematurity of motion cited—better case after institution |
| Effect of estoppel (35 U.S.C. § 315(e)) on stay analysis | N/A—points to unfairness if defendant rides third party’s petition without being estopped | IPR of all claims could simplify case; PTAB analysis would aid court even if defendant not petitioner | Because defendant is not the petitioner and did not accept estoppel, potential efficiencies are reduced; this weighs against stay |
| Stage of litigation and judicial/party resources expended | Advanced procedural posture (extensive discovery, many rulings, partial SJ) makes stay inappropriate | Some discovery remains and trial not yet held; IPR would conclude before trial, so stay could conserve resources | Court found substantial prior investment and narrowed issues; this militates against stay |
