Material Changes and Events
On April 13, 2026, Atossa Therapeutics entered into a Settlement Agreement with Intas Pharmaceuticals Ltd. and Jina Pharmaceuticals, Inc. to resolve patent disputes regarding Endoxifen-related intellectual property. Key terms include:
- PTAB Proceedings: Parties agreed to seek termination of pending challenges before the U.S. Patent and Trademark Office Patent Trial and Appeal Board (PTAB). If not fully terminated, parties agreed not to participate further.

- Commercial Rights: The agreement preserves Atossa's ability to develop and commercialize Z-endoxifen base in oncology, endocrine dysfunction disorders, and muscular dystrophy-related diseases.
- Field Allocations: Agreed allocations were established for certain other Endoxifen-related fields and formulations.
- Patent Status: Upon anticipated PTAB termination, two issued patents (U.S. Patents Nos. 11,261,151 and 12,071,391) are expected to remain issued and fully enforceable against third parties.
