778 F.3d 1327
Fed. Cir.2015Background
- United Access Technologies (successor to Inline) owns three patents covering systems that combine and filter voice and data for transmission over a telephone line (ADSL-related claims).
- Inline sued EarthLink in 2002 for infringement; EarthLink defended that (a) industry-standard ADSL did not infringe and (b) EarthLink’s accused service lacked a required "telephone device."
- A jury returned a general verdict of non-infringement in the EarthLink case; the verdict did not specify which ground the jury relied on. The district court denied Inline’s JMOL. This court affirmed without opinion.
- United later sued CenturyTel and Qwest for infringing the same patents. Defendants moved to dismiss based on collateral estoppel, arguing the EarthLink verdict already established non-infringement of industry-standard ADSL.
- The district court applied collateral estoppel, relying on the EarthLink trial court’s JMOL ruling that the jury reasonably could have found non-infringement on either alternative ground. United appealed.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Whether a prior general jury verdict of non-infringement can collaterally estop litigation that industry-standard ADSL infringes where the jury could have relied on multiple grounds | The EarthLink JMOL did not establish that the jury necessarily decided the ADSL-infringement issue; thus collateral estoppel does not apply | The EarthLink JMOL showed the verdict was supportable on the ADSL non-infringement theory, so collateral estoppel should bar relitigation | Reversed: collateral estoppel does not apply because the general verdict could have rested on an alternative ground (absence of a telephone) and the record does not show the jury necessarily decided the ADSL issue |
| Whether an earlier court’s JMOL sufficiency ruling (that evidence could support alternative grounds) gives preclusive effect to each alternative ground | JMOL that evidence was sufficient on multiple grounds does not prove the jury actually decided each ground; estoppel requires the issue to have been actually and necessarily decided | JMOL sufficiency on alternative grounds supports preclusion of those grounds under Third Circuit authority embracing preclusion of alternative holdings | The court distinguished Jean Alexander: where a prior tribunal expressly decided alternative grounds, preclusion can apply; a JMOL finding that a jury could have relied on multiple grounds is not the same and does not satisfy necessity for preclusion |
