Cannabis Cultivar Identity Expert Witness

Cultivar identity sits at the center of a growing number of cannabis disputes: theft of genetics, substitution of licensed material, contested ownership of proprietary strains, and fraud in transactions involving named varieties. I provide expert witness services in these cases, applying SNP-based genomic fingerprinting and molecular biology to establish, contest, or interpret genetic identity claims.

Most cannabis expert witnesses bring cultivation or business operations experience. I bring the molecular science. When the question is whether two plants share a common genetic identity, or whether a claimed cultivar is what it's represented to be, that's a genetics question before it's anything else.

What I provide

Genomic identity analysis. SNP-based fingerprinting using reduced representation sequencing to assess genetic identity, relatedness, or distinction between samples, with analysis and reporting built for legal proceedings.

Expert opinion on identity claims. Assessment of whether genetic evidence supports or contradicts a cultivar identity claim, including review of opposing expert analyses.

Rebuttal analysis. Technical review and rebuttal of genomic analyses, fingerprinting methodologies, or identity claims submitted by opposing experts.

Expert reports and testimony. Written findings documenting methodology, chain of custody considerations, and the scientific basis for every conclusion, plus deposition and trial testimony in state and federal proceedings. Prepared for cross-examination.

Case Types

Genetics theft and cultivar misappropriation. Clone substitution in licensed transactions. Strain identity fraud in commercial sales. Contested ownership of proprietary genetics. Cultivar identity in patent and PVP proceedings. Expert rebuttal on competing genomic analyses. Identity verification in breeding program disputes.

The science behind cultivar identity

Cannabis cultivar identity at the genomic level is assessed through SNP-based fingerprinting: comparing single nucleotide polymorphism profiles across samples to determine whether they share a common genetic origin. A clonal lineage carries essentially the same profile no matter how it was grown, what it was called, or where it changed hands. The sequence doesn't change when you top the plant. It doesn't change when you cross state lines. It doesn't change when someone gives it a different name.

Somatic mutation does accumulate across long propagation histories. That's why the analysis reports how closely two samples match and what that supports, rather than declaring them identical if they aren't.

Disclosure and conflicts

I'm a co-founder and CEO of True Cut, a cannabis genomic identity and IP verification platform. My expert witness work operates independently of it, and I don't serve as an expert in matters where True Cut has a prior or existing client relationship. That separation is deliberate.

I run a conflicts check before every engagement.
