Formally protected. Independently verifiable. Published by WIPO

The formulations and peptides derived from Heteroctenus junceus blue scorpion venom are now protected under international intellectual property law — filed under the Patent Cooperation Treaty and published by the World Intellectual Property Organization in November 2025.

PCT Patent

What a PCT patent
application means

A PCT (Patent Cooperation Treaty) application is an international patent filing that simultaneously seeks protection in over 150 countries through a single procedure administered by the World Intellectual Property Organization (WIPO).

Publication by WIPO means the invention has been formally registered, assigned an international publication number, and made publicly accessible in the global patent database — Patentscope.

These two applications represent the formal intellectual property protection of 18 years of scientific research on blue scorpion venom compounds.

These are international patent applications currently in the evaluation phase. They have been published by WIPO but have not yet been granted. Patent applications do not imply FDA approval. NDC registration is separate from patent status.
