The '638 patent is dead, removing overhang from the most substantive part of this case. The '978 patent remand is low-probability for TrackTime given the difficulty of overcoming means-plus-function invalidity. No damages, no injunction, no ongoing risk to Amazon's operations. Amazon's litigation win is clear. No further action warranted.

Executive Summary
The Federal Circuit largely affirmed Amazon's win in this patent infringement case brought by TrackTime. The key holding is that the jury's finding of anticipation by LiveNote for the '638 patent is supported by sufficient evidence, and the district court properly denied TrackTime's post-trial motions. However, the Court vacated and remanded the ruling on the '978 patent claims, finding the district court's means-plus-function analysis was insufficient in light of intervening precedent (Dyfan). This is a net positive for Amazon, removing the most material risk from the '638 patent and sending only the narrower '978 patent issues back for further proceedings with no guarantee of an adverse outcome.
Court Ruling Details
Key Facts
- Federal Circuit affirmed jury finding that LiveNote anticipates claim 9 of TrackTime's '638 patent.
- This ruling is a final judgment against TrackTime on the '638 patent; it resolves the most significant patent asserted in this case against Amazon.
- The Court vacated the district court's indefiniteness ruling on the '978 patent and remanded for further analysis under the Dyfan framework.
- The '978 patent claims (annotation and synchronous play) are still at issue but the Federal Circuit did not rule that they were valid or invalid — just that more analysis is needed.
- No damages were awarded to TrackTime at any stage of this case; the litigation result is a complete win for Amazon on the '638 patent.
- Amazon, with a ~$2.6T market cap, faces no material financial exposure from this ruling.
- The '978 patent remand is a narrow issue of claim construction — it does not reinstate any infringement finding or damages.
Financial Impact
No damages awarded against Amazon. The patents at issue are from a non-practicing entity and the ruling eliminates the main asserted patent entirely. The only remaining patent (the '978) is on remand for claim construction, not for damages.
Risk Factors
- On remand, the district court could potentially revive the '978 patent claims, but that would only restart the case on narrow claims — no infringement finding exists.
- TrackTime could appeal the '638 ruling to the Supreme Court, but certiorari is exceedingly unlikely in a routine patent anticipation case.
