Narrative Opinion Summary
In this patent infringement case, Pulse Medical Instruments, Inc. (PMI) filed a complaint against Drug Impairment Detection Services, Inc. (DIDS) following the termination of their distribution agreement. The primary legal issue revolves around the admissibility of expert testimony concerning damages, analyzed under Federal Rule of Evidence 702 and the standards established by Daubert and Kumho Tire Co. Both parties moved to exclude the other's expert testimony, with PMI challenging the qualifications and methodology of DIDS's expert, Mr. Harkavy, and DIDS contesting the approach of PMI's expert, Mr. Valeiras. The court denied both motions, emphasizing the broad interpretation of expert qualifications and the admissibility of testimony grounded in reliable methods. Mr. Harkavy's use of Georgia-Pacific factors was upheld as a valid framework for calculating reasonable royalties, while Mr. Valeiras's alternative 'lost opportunity' damages method was deemed admissible despite not adhering to traditional factors. The court highlighted that issues of expert bias pertain to credibility, which is a determination for the jury. Ultimately, the court’s rulings permit both experts to testify, focusing on their analyses' relevance and reliability rather than specific methodological adherence, and the confidentiality of certain expert reports is maintained pending further proceedings.

Application: Mr. Valeiras’s alternative 'lost opportunity' method for calculating damages is admissible, despite not using Georgia-Pacific factors, as it provides a reasonable approach under the circumstances of the case.
Reasoning: Mr. Valeiras posits that the facts of this case differ significantly from typical patent infringement cases, suggesting the need for an alternative damages calculation method.
Application of Georgia-Pacific Factors in Patent Damagessubscribe to see similar legal issues
Application: Mr. Harkavy’s use of the Georgia-Pacific factors in his analysis of reasonable royalty rates is considered appropriate and admissible for aiding the trier of fact in determining patent infringement damages.
Reasoning: Mr. Harkavy’s references to these factors in his report are thus deemed reasonable and contextually relevant to the case at hand, countering PMI’s assertion that it constitutes testimony on legal questions.
Evaluating Expert Bias and Credibilitysubscribe to see similar legal issues
Application: Allegations of expert bias are considered issues of credibility for the jury to assess and do not impact the admissibility of expert testimony.
Reasoning: Consequently, DIDS’s final argument regarding alleged bias is dismissed, as bias pertains to credibility, which is for the jury to assess, not a factor in determining expert qualifications.
