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 establish genetic identity, relatedness, or distinction between samples, with analysis and reporting built for legal proceedings.

Cultivar identity reports. Written findings documenting methodology, chain of custody considerations, and the scientific basis for every conclusion, prepared to withstand cross-examination.

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

Prior art and novelty assessment. Evaluation of whether a claimed cultivar is genetically distinct from publicly available or previously documented material, relevant to patent, PVP, and trade secret matters.

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

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

Cultivar identity at the genomic level is established through SNP-based fingerprinting, comparing single nucleotide polymorphism profiles across samples to determine whether they share a common genetic origin. It's analogous to forensic DNA fingerprinting in human identity cases. The same plant produces the same genomic profile regardless of how it was grown, what it was called, or how many times it was propagated.

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.

That stability is what makes genomic fingerprinting the right evidentiary tool for identity disputes. Phenotype, including chemotype, shifts with environment. The genome is the one identity layer in a plant that holds still.

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.
