Degrees of Disagreement: Google Petitions En Banc on Smart Thermostat Patent Damages

In the recent case of EcoFactor, Inc. v. Google LLC, the Federal Circuit affirmed a $20 million jury verdict for EcoFactor, a smart thermostat company, against Google. The case centers around U.S. Patent No. 7,461,353, which claims technology for optimizing HVAC systems using temperature measurements. The decision has sparked significant debate, particularly concerning the damages awarded and the methodology used by EcoFactor's damages expert, David Kennedy.

The Core Issues

Google has filed a petition for en banc review, raising critical questions about the Federal Circuit panel's decision. The company contends that the decision "contradicts this Court’s precedent" on patent damages and that it could substantially lower the threshold for admissibility of expert opinions based on comparable portfolio licenses.

The petition focuses on two main issues:

  1. Reliance on Self-Serving Recitals: Google's primary concern is that Kennedy based his damages calculations on self-serving recitals in prior license agreements. These recitals were not supported by the actual terms of the agreements, which were primarily lump-sum payments rather than per-unit royalties. Google argues that this reliance on recitals is insufficient and inconsistent with Federal Circuit precedent, which requires concrete evidence to support damages calculations.

  2. Failure to Properly Apportion Value: Google also challenges Kennedy's methodology for apportioning the value of the asserted patent from other patents in comparable licenses. The company argues that Kennedy's testimony, which discussed "upward and downward pressure" on the royalty rate without specific, quantifiable evidence, failed to meet the rigorous standard required for apportionment in patent cases.

The Panel's Decision and Judge Prost's Dissent

In the original opinion, Judges Reyna and Lourie upheld the district court's decision to admit Kennedy's testimony and the resulting damages award. The majority concluded that Kennedy's analysis was sufficiently tied to the evidence and that he adequately accounted for differences between the comparable licenses and the hypothetical negotiation at issue.

However, Judge Prost dissented, criticizing the majority for accepting what she viewed as speculative and unreliable testimony. She argued that the majority's decision undermined the requirement for rigorous apportionment in patent damages cases, potentially setting a dangerous precedent for future litigation.

The En Banc Petition: Arguments and Implications

Google's en banc petition echoes Judge Prost's concerns, emphasizing the need for strict adherence to the principles of apportionment and the use of concrete evidence in damages calculations. The company warns that the panel's decision could open the door to inflated damages awards based on unreliable expert testimony, thus disrupting the balance in patent litigation.

Key Arguments in the Petition:

  • Concrete Basis for Royalty Calculations: Google contends that self-serving recitals in license agreements are not a reliable basis for calculating royalties. The company points to previous cases, such as Apple v. Wi-LAN, where similar testimony from the same expert was rejected.

  • Rigorous Apportionment Requirement: The petition argues that general discussions of "upward and downward pressure" are insufficient for apportioning value between patents. Google stresses that apportionment must be based on hard evidence, not generalized expert opinion.

Conclusion and Future Considerations

The Federal Circuit's decision in EcoFactor v. Google raises important questions about the standards for expert testimony and damages calculations in patent cases. Google's en banc petition underscores the tension between ensuring fair compensation for patent infringement and preventing inflated damages awards based on speculative testimony.

As the court considers the petition, the outcome will likely have significant implications for patent litigation, particularly concerning the role of expert testimony in determining damages. A decision to grant en banc review could lead to a reevaluation of the standards for admissibility and reliability of expert opinions, potentially reshaping the landscape of patent damages law. For now, the case serves as a critical reminder of the complexities involved in patent litigation and the importance of rigorous legal standards in ensuring just outcomes.
