771 F.3d 1368
Fed. Cir.2014Background
- Versata sued Callidus for infringement of three patents (the ’326, ’304, and ’024 patents) relating to managing/tracking sales information; suit filed July 19, 2012 in D. Del.
- Callidus moved to transfer and to dismiss; both motions were denied in May 2013; Callidus then counterclaimed and announced plans to seek CBM review and a stay.
- Callidus filed initial CBM petitions in Aug. 2013 challenging many claims under 35 U.S.C. § 101; the PTAB instituted CBM review for the first petitions in Mar. 2014 (finding claims likely unpatentable under § 101).
- Callidus filed additional CBM petitions challenging the remaining asserted claims of the ’024 and ’304 patents; the PTAB later instituted review of those petitions as well.
- The district court granted a stay as to the ’326 patent (where all claims were challenged) but denied a stay as to the ’024 and ’304 patents; Callidus appealed the partial denial.
- The Federal Circuit reviewed the four statutory factors in AIA § 18(b) and reversed, holding that the factors—taken together—weighed strongly in favor of staying the action as to the ’024 and ’304 patents.
Issues
| Issue | Plaintiff's Argument (Versata) | Defendant's Argument (Callidus) | Held |
|---|---|---|---|
| Whether a stay pending CBM review would simplify issues and streamline trial | CBM addresses only § 101 on a subset of claims; many issues (other invalidity defenses, unchallenged claims, counterclaims) remain | Even partial CBM review can substantially simplify issues; PTAB institution on independent claims and later all claims likely to simplify or dispose of litigation | Stay favored: simplification factor strongly favors stay (district court erred by applying a categorical rule) |
| Whether the stage of litigation (discovery/trial date) disfavors a stay | Discovery had progressed by district court decision; resources already spent, trial approaching | Motion to stay was filed when litigation was in infancy; at relevant times discovery and claim construction were incomplete | Stay favored: timing/discovery factor strongly favors stay (district court should evaluate status at motion filing/PTAB institution) |
| Whether a stay would unduly prejudice plaintiff or confer tactical advantage to defendant | Staying Versata’s claims while Callidus pursues counterclaims gives Callidus an unfair tactical advantage and prejudices Versata | Callidus sought a stay of the entire litigation; no factual findings show undue prejudice to Versata | Stay favored: no undue prejudice found; factor strongly favors stay (district court made erroneous factual findings) |
| Whether a stay would reduce the burden of litigation on the parties and court | Prior motions and litigation activity increased burden; stay would not reduce overall burden | A stay would avoid future burdens (claim construction, expert discovery, trial) especially if PTAB invalidates claims | Stay favored: prospective burden reduction strongly favors stay (district court erred by focusing on past filings) |
