955 F.3d 990
Fed. Cir.2020Background
- Mossberg sued Timney in 2012 for infringement of U.S. Patent No. 7,293,385 after licensing talks failed.
- Timney pursued multiple PTO post-grant proceedings (inter partes and ex parte reexaminations) and the district court stayed the district-court case pending those proceedings for over five years.
- The PTO (PTAB) ultimately invalidated the patent claims as obvious during reexamination.
- After the invalidation, Mossberg filed a voluntary dismissal under Fed. R. Civ. P. 41(a)(1)(A)(i); the dismissal was effective on filing and was entered in the district court docket.
- Timney moved for attorney’s fees under 35 U.S.C. § 285, claiming it was the prevailing party due to the PTO invalidation and the district court’s long stay.
- The district court denied fees, concluding no judicial imprimatur or final court decision altered the parties’ legal relationship; Timney appealed.
Issues
| Issue | Plaintiff's Argument (Mossberg) | Defendant's Argument (Timney) | Held |
|---|---|---|---|
| Whether Timney is a "prevailing party" under 35 U.S.C. § 285 | Timney is not prevailing because dismissal under Rule 41(a)(1)(A)(i) is not a judicial decision on the merits and provides no judicial imprimatur. | Timney is prevailing because the district court’s stay plus PTO invalidation and the subsequent voluntary dismissal materially altered the parties’ legal relationship. | Timney is not a prevailing party; no final court decision or judicial imprimatur existed to alter the legal relationship for § 285 purposes. |
| Whether the district court’s multi-year stay provided the judicial imprimatur required to confer prevailing-party status | Stay alone does not effect a judicially sanctioned change in legal rights; only a final court decision can do so. | The stay authorized the PTO proceedings as an alternative forum and thus amounted to judicial imprimatur supporting fee entitlement. | A stay, by itself, is not a final decision and cannot supply the required judicial imprimatur. The PTAB invalidation and plaintiff’s voluntary Rule 41 dismissal — not a court judgment — controlled, so fees are not available. |
