Spectroscopy Expert Witnesses

Spectroscopic data sits at the center of many high-stakes commercial disputes because it is often the most objective record of what a material actually is. Patent owners rely on Raman, infrared, or NMR spectra to prove that an accused product contains a claimed compound, crystal form, or structure, while accused infringers use the same techniques to show that it does not. Supply and quality disputes raise parallel questions when a buyer alleges that a chemical, pharmaceutical ingredient, or specialty material failed to meet specification or arrived contaminated. Because spectra must be interpreted rather than simply read, the contest usually turns on whether the sample, the method, and the conclusions drawn from them are reliable.

A spectroscopy expert helps counsel determine whether the analytical evidence can bear the weight a party places on it. That review typically starts with sample selection, chain of custody, and preparation, then moves to instrument calibration, reference standards, spectral assignments, and any chemometric models used to interpret the results. In patent cases, the analysis ties specific spectral features to claim limitations, supporting infringement or non-infringement positions and informing validity challenges that depend on characterizing prior art. In contract and contamination disputes, the same rigor can establish or refute that a nonconforming material caused a downstream failure and can quantify its extent for damages purposes. An expert who understands both the underlying physics and method-validation expectations can also surface flaws in an opposing laboratory's work that are invisible in a data summary.

Spectroscopy spans techniques with distinct theoretical foundations and practical pitfalls, and an expert fluent in NMR may be poorly positioned to defend a laser-induced breakdown or resonance Raman analysis. Our network includes physical and analytical chemists, molecular physicists, and biomolecular spectroscopists who have published on Raman and vibrational spectroscopy, NMR applications in petroleum and specialty chemicals, and hyperspectral imaging. Several hold senior academic appointments and have built substantial patent and publication portfolios, some have founded companies to commercialize spectroscopic technology, and others have testified on Raman spectroscopy, metallurgy, and contamination. Drawing on more than 75,000 expert searches for litigators, Round Table Group can help you find the analytical specialist whose methods match the evidence in your matter.
