(“Extreme”). Plaintiffs retained [Mark Chandler](https://expertwitnessprofiler.com/expert-witness/Mark-Chandler/1548220) to issue an opinion about “agreements and negotiations related to the licensing, development and commercial use of software, copyrights, and other intellectual property.” According to Chandler, Plaintiffs’ previous settlement agreements with third parties are “relevant because they demonstrate [Plaintiffs’] licensing practices under conditions that are similar to their current dispute with [Defendant].” ## **Intellectual Property Expert Witness** [Mark Chandler](https://expertwitnessprofiler.com/expert-witness/Mark-Chandler/1548220) is the founder of Upstream Partners and a recognized expert in commercializing intellectual property (IP) and technology. Chandler completed his undergraduate studies in electrical engineering (BSEE, Bucknell University), and continued his technical education in physics while working at the Johns Hopkins Applied Physics Lab. He practiced as a researcher building the world’s most accurate atomic clocks and implantable medical devices, and obtained his MBA from the Wharton School of the University of Pennsylvania. He has testified as a financial damages expert and as a licensing expert, on behalf of both Plaintiffs and Defendants, for patent litigation and contract dispute matters in U.S. District Court, state courts and arbitration proceedings.

Plaintiffs have not sufficiently explained why Chandler’s analysis of previous settlement agreements are related to Defendant’s liability for breach of contract, copyright infringement, or fraud. Nor have they explained how Chandler’s opinions are relevant to their damages. The Court held that Chandler generally discusses the circumstances of Plaintiffs’ previous settlements and his opinions on why Plaintiffs and the third parties arrived at the settlement amount. But he “does not even purport to analyze Plaintiffs’ previous settlements for the purposes of extracting licensing rates that might inform the value of its copyrighted software.” Nor did he connect his summary of Plaintiffs’ three previous settlements to any standard practices and customs. ## **Held** The Court granted Defendant’s motion to exclude the opinions of Mark J. Chandler. ## **Key Takeaway:** Under the circumstances, Plaintiffs did not sufficiently explain why Chandler’s analysis of their previous settlement agreements will assist the jury to understand the evidence or to determine a fact in issue. ## **Case Details:** --- ## **You Might Also Like** ![Law And Legal Expert Was Allowed to Opine on Claims Handling Customs ](https://media.jurimatic.com/images/Expert_Witness_Profiler1.webp) [**Law And Legal Expert Was Allowed to Opine on Claims Handling Customs **](https://expertwitnessprofiler.com/intellectual-property-experts-opinion-on-settlement-licenses-excluded/law-and-legal-expert-was-allowed-to-opine-on-claims-handling-customs-)![Psychology Expert's Testimony About PICS Limited](https://media.jurimatic.com/images/blog_pic_640X4801.webp) [**Psychology Expert's Testimony About PICS Limited**](https://expertwitnessprofiler.com/intellectual-property-experts-opinion-on-settlement-licenses-excluded/psychology-experts-testimony-about-pics-limited)![Finance Expert Allowed to Opine on Damages and Disgorgement](https://media.jurimatic.com/images/blog_pic_640X480_2026_07_23T203933_056.webp) [**Finance Expert Allowed to Opine on Damages and Disgorgement**](https://expertwitnessprofiler.com/intellectual-property-experts-opinion-on-settlement-licenses-excluded/finance-expert-allowed-to-opine-on-damages-and-disgorgement)![Psychology Expert Allowed to Opine on False Confessions](https://media.jurimatic.com/images/blog_pic_640X480_2026_07_21T175218_265.webp) [**Psychology Expert Allowed to Opine on False Confessions**](https://expertwitnessprofiler.com/intellectual-property-experts-opinion-on-settlement-licenses-excluded/psychology-expert-allowed-to-opine-on-false-confessions)![Privacy Expert Was Not Allowed to Opine on ECPA and SCA](https://media.jurimatic.com/images/blog_pic_640X480_2026_07_22T201120_732.webp) [**Privacy Expert Was Not Allowed to Opine on ECPA and SCA**](https://expertwitnessprofiler.com/intellectual-property-experts-opinion-on-settlement-licenses-excluded/privacy-expert-was-not-allowed-to-opine-on-ecpa-and-sca)
