Patent Damages

Introduction: The ongoing debate over the application of Daubert standards to patent damages expert testimony has taken center stage in the case of EcoFactor v. Google. The Federal Circuit's decision in this case has sparked significant concern among tech giants, leading to an en banc petition by Google. This has prompted a wave of support from various industry leaders, all advocating for stricter scrutiny of damages calculations and expert reliability in patent litigation. In this blog, we explore the key issues raised by Google and its supporters, and the broader implications for patent damages and expert testimony.

Background on the Case: In EcoFactor v. Google, EcoFactor's damages expert, David Kennedy, relied on prior patent licenses to calculate a royalty rate for Google's use of their smart thermostat patent. However, these licenses were lump-sum agreements covering multiple patents, while the case at hand involved only a single patent. Google argued that Kennedy's approach was flawed and unscientific, leading to unreliable and inflated damages estimates. Despite Google's objections, the courts have so far sided with EcoFactor, prompting Google's petition for en banc review by the Federal Circuit.

The Daubert Standard and Patent Damages: The Daubert standard, established in Daubert v. Merrell Dow Pharmaceuticals, Inc. (1993), requires that expert testimony be both relevant and reliable, with a methodology that can withstand scrutiny. In patent cases, this means that damages experts must provide scientifically valid methods and conclusions, particularly when it comes to apportionment—ensuring that damages are properly attributed to the patented feature rather than the entire product or portfolio.

Amicus Briefs in Support of Google's Petition: Several major tech companies, including Apple, Cisco, Intel, and Dell, have filed amicus briefs supporting Google's position. These briefs argue that the current approach to expert testimony in patent damages is inadequate and fails to ensure that damages are apportioned correctly. They highlight the need for stricter enforcement of the Daubert standard to prevent the misuse of licensing data and to avoid excessive damages awards that can distort the market.

  1. Cisco's Perspective on Portfolio Apportionment: Cisco's brief emphasizes that no reasonable party would pay the entire portfolio rate for a single patent. Instead, they argue for a value-based licensing approach that isolates the value of the patented feature. Cisco's method involves detailed internal profit data, which they argue provides a more accurate and fair assessment of damages. However, this approach also raises concerns about the potential for increased discovery demands and the protection of sensitive business information.

  2. Apple's Emphasis on Robust Daubert Enforcement: Apple's brief underscores the importance of proper apportionment, particularly as products become more complex. They argue that jurors are often ill-equipped to evaluate unreliable and unapportioned damages theories, which can lead to inflated and unfair damages awards. Apple's experiences in litigation highlight the dangers of relying on manufactured running-royalty rates from non-comparable licenses, which can distort the true value of a patent.

  3. US*MADE's Focus on Expert Reliability: The U.S. Manufacturers Association for Development and Enterprise (US*MADE) takes issue with the reliance on self-interested data provided by patentees, which they argue should not be considered reliable under Daubert. Their brief calls for greater scrutiny of the data sources used by damages experts, particularly in cases where patentees structure licensing agreements to generate misleading "comparable" licenses for litigation purposes.

The Broader Implications: The outcome of Google's en banc petition in EcoFactor v. Google could have significant implications for patent litigation and damages calculations. A stricter application of the Daubert standard could lead to more rigorous scrutiny of expert testimony, potentially reducing the number of excessive damages awards. However, it could also increase the complexity and cost of patent litigation, as parties may need to invest more in developing and defending their damages models.

Conclusion: The EcoFactor v. Google case has brought to the forefront critical issues surrounding the reliability of expert testimony in patent damages cases. As the Federal Circuit considers Google's en banc petition, the legal community is watching closely to see whether the court will adopt a more stringent approach to Daubert and apportionment. For companies involved in patent litigation, the outcome could shape the strategies they use in defending against damages claims and influence how they approach licensing negotiations and damages calculations in the future.
