Licensing Cas-CLOVER for Commercial Bioprocessing

A clear path to commercial freedom, predictable costs, and uninterrupted editing from cell line engineering to biomanufacturing.

Cas-CLOVER is a high-precision genome editing platform designed to replace CRISPR/Cas9 in bioprocessing and cell line engineering workflows. It provides a clear path to freedom to operate, predictable licensing costs, and uninterrupted editing from discovery through biomanufacturing.

Why Companies Still Struggle to Adopt CRISPR/Cas9

Across the biopharmaceutical industry, CRISPR/Cas9 remains difficult to deploy on a commercial level, because of the business realities around it.

1. A deeply fragmented IP landscape

Cas9 is covered by thousands of patents and at least 500+ unique applicants, with foundational patents extending to at least 2033. Even companies that secure multiple Cas9 licenses still face uncertainty, continual diligence, and the risk that additional rights may be required downstream.

2. Limited technology transfer and know-how

Most Cas9 licensors provide minimal hands-on support. As a result, organizations are left to build editing expertise internally, developing protocols from scratch, relying on scattered peer reviewed methods, and troubleshooting reproducibility challenges without guided technical transfer.

Removing Barriers to Industrial Gene Editing

Cas‑CLOVER® is a clean alternative to CRISPR/Cas9, purpose‑built for cell line development (CLD), cellular engineering, and bioprocessing. The system’s dimeric nuclease architecture enables high‑efficiency gene editing with markedly reduced off‑target activity, supporting reliable performance in production‑oriented workflows.
All components of the Cas‑CLOVER® system—including dCas9, guide RNAs, the Clo051 nuclease, and the overall platform architecture—are in‑licensed under a consolidated, conflict‑free IP position.

This unified intellectual property framework eliminates downstream uncertainty and supports confident progression from research to commercialization.
Demeetra’s licensing model maintains predictable costs, clear freedom to operate, and continuity of engineered cell lines across research, development, and GMP manufacturing, eliminating the need to rebuild clones due to technology switching. Licensing and deployment are supported by the same scientists who engineered and validated the platform, enabling efficient technology transfer that accelerates internal adoption and reduces operational risk.

Licensing Options: Flexible & Future-Proof

Perpetual Commercial License

  • Unlimited, perpetual commercial cell line development and bioprocessing
  • One simple fee, no royalties
  • Includes 12 months of full technical support
  • Access to all Cas-CLOVER technology available at signing

Enterprise Platform Subscription – 36 Months (EPS-36)

  • Three-year subscription that automatically converts to a perpetual license
  • Access to new technologies as they are released
  • Includes 60 vials/year of Cas-CLOVER or Harbor-IN reagents for stable cell engineering
  • Full technical support for the entire 36-month term

Cas-CLOVER Business Advantages

Comprehensive Freedom to Operate (FTO)

  • Cas-CLOVER is built entirely from clean, consolidated IP with only three applicants across the key editing enzyme Clo051 (Helmholtz, Poseida, Demeetra).
  • dCas9 + gRNA rights are secured through ERS Genomics under the CVC portfolio, covering fully inactive dCas9 only, the sole Cas protein used in Cas-CLOVER.
  • Avoid the ~20,000 Cas9 patent records and 500+ applicants that create uncertain FTO and recurring diligence obligations.

Cost Certainty at Scale

  • Pipeline-wide commercial access fee. No royalties or milestones for biopharma end-users.
  • Avoid escalating fees as pipelines grow (yearly fees + milestones + royalties).
  • Predictable budgeting empowers long-range portfolio planning for biologics, ADCs, engineered antibodies, AAV components, and more.
  • Optional evaluation period and R&D license supported directly by Demeetra scientists.

Continuity from Discovery to Manufacturing

  • Cas9 workflows often break between discovery and GMP production due to FTO constraints; forcing re-engineering, re-licensing, and loss of validated clones.
  • Cas-CLOVER provides a single platform used identically during discovery, development, and manufacturing.
  • Protects R&D investment by ensuring every validated clone remains commercially viable.
