817 F.3d 1316
Fed. Cir.2016Background
- Cardpool sued Plastic Jungle for infringement of U.S. Patent No. 7,494,048; the district court dismissed under Rule 12(b)(6) holding the asserted claims patent-ineligible under 35 U.S.C. § 101 and entered judgment with prejudice.
- The Federal Circuit initially affirmed under Rule 36, then Cardpool requested ex parte reexamination; the PTO issued a reexamination certificate allowing amended and new claims (claims 1, 2–7, 9–11 amended; 12–52 new) as nonobvious under § 103.
- After the PTO certificate, the Federal Circuit granted rehearing, vacated its summary affirmance, and remanded to the district court to decide appropriate actions; it declined to vacate the district court judgment, noting Cardpool caused the change in circumstances.
- Back in district court, Cardpool and Plastic Jungle jointly moved to vacate the judgment (so they could dismiss without prejudice), asserting the original claims no longer existed and the case was moot because Plastic Jungle ceased the accused activity.
- The district court denied vacatur, reasoning vacatur was inappropriate where mootness resulted from the losing party’s voluntary act and an examiner’s allowance does not displace a contested court judgment; the court declined to review the reexamined claims because the litigation was moot by the parties’ agreement.
- The Federal Circuit affirmed the district court’s denial of vacatur, holding the denial was within the district court’s discretion and that final judgment as to original claims does not automatically bind new reexamined claims.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Whether the district court should vacate its judgment dismissing the original claims with prejudice after PTO reexamination allowed amended/new claims | Cardpool: vacatur required because the original claims no longer exist; preserving "with prejudice" could bar enforcement of reexamined claims later | Plastic Jungle: vacatur improper; mootness resulted (parties previously said case was moot) and Cardpool caused the change | Court: Denial of vacatur was within discretion; losing party’s voluntary act weighs against vacatur and allowed PTO action does not automatically overturn prior judgment |
| Whether the case was moot and whether mootness caused by Cardpool bars vacatur | Cardpool: case not entirely moot; infringement of reexamined claims could recur | Plastic Jungle: case moot; reexamination changed claims so prior rulings must be vacated and case dismissed | Court: Parties jointly represented the case moot; Ninth Circuit equitable standards permit declining vacatur when appellant’s act caused mootness |
| Whether a dismissal with prejudice as to original claims bars later enforcement of reexamined claims (res judicata/Aspex concern) | Cardpool: dismissal "with prejudice" could estop enforcement of reexamined claims; court should avoid creating res judicata effect on new claims | Plastic Jungle: prior positions suggested full mootness and supported vacatur; later opposition inconsistent | Court: Res judicata depends on factual comparison; final judgment does not automatically bind claims that did not exist or were materially different; issue remains for any future suit |
| Whether the district court erred by refusing to evaluate the reexamined claims on § 101 grounds | Cardpool: district court should reconsider validity of amended claims and give effect to PTO certificate | Plastic Jungle: argued Cardpool didn’t show amended claims differed; inconsistent positions about mootness | Court: No abuse of discretion—district court need not decide new-claim validity when parties agreed the action was moot and there was no live controversy |
