Atlantic Research Marketing Systems, Inc. v. Troy
659 F.3d 1345
Fed. Cir.2011Background
- Atlantic Research and Troy dispute ownership and scope of a free-floating handguard system for firearms.
- The district court invalidated claims 31–36 of the '465 patent for failing to meet the written description and best mode requirements.
- The district court construed claim 31 as barrel-nut–only support, then held the specification failed to disclose such a design.
- Atlantic Research challenged the claim construction and written-description analysis on appeal.
- Troy challenged the verdict on trade-secret misappropriation and sought a mistrial and remittitur; the district court denied these motions, which the court partially reversed.
- The court vacated the verdict on taint grounds and remanded for a new trial on taint issues, and affirmed in part on written description while declining to address best mode and remittitur.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Written description invalidity of claims 31–36 | Atlantic Research contends the barrel-nut-only attachment is disclosed | Troy argues claims 31–36 are supported by the specification | Claims 31–36 invalid for lack of written description |
| Trade-secret JMOL and sufficiency of evidence | Atlantic Research identified the trade secret prototype and evidence | Troy argues no exceedance beyond the '245 patent disclosed | District court's denial affirmed: jury could find possession of trade secret |
| Jury taint and mistrial | District court inadequately investigated clamp presence | Mistrial unnecessary if prejudice not shown | Vacate verdict and reverse denial of mistrial; remand for new trial on taint issues |
| Best mode/remittitur | Not reached or argued | Not reached | Not addressed in light of written-description ruling and taint reversal |
