MADISON, WI USA (September 27, 2024) Porta Sophia filed a third-party preissuance submission with the United States Patent and Trademark Office (USPTO) today for U.S. Pat. App. Ser. No. 18/675,614 entitled “5-METHOXY-N,N-DIMETHYLTRYPTAMINE (5-MEO-DMT) FOR TREATING DEPRESSION”, which is currently assigned to GH RESEARCH IRELAND LIMITED. The submission consisted of 21 prior art documents that are material to the patentability of all 30 claims of the application.

Porta Sophia, a non-profit psychedelic prior art library, leverages the experience of legal and interdisciplinary academic scholars to promote an ethical psychedelic patenting landscape that preserves the integrity of the public domain. The organization curates and makes relevant historical documentation readily available for anyone wanting to explore the scope of psychedelic technologies, including patent examiners.

Patent application: therapeutic use of 5-MeO-DMT for major depressive disorder

The ’614 application was filed on May 28, 2024. It describes methods for treating depressive disorders, including major depressive disorder (MDD) and treatment-resistant forms, using 5-MeO-DMT or its pharmaceutically acceptable salts. The claims cover a range of treatment protocols, including dosing strategies to induce peak psychedelic experiences, rapid symptom relief, and clinical improvements measured through established depression scales. Additionally, the claims also cover patients at risk of suicide and those experiencing suicidal ideation.

Prior art in the third-party preissuance submission included U.S. patent documents, peer reviewed journal articles and online blogs such as Erowid. This prior art anticipates claims in the ’614 application. The full third-party submission documentation is available here.

Third-party submissions of prior art

United States patent law allows third parties to submit prior art and concise descriptions of their relevance to the USPTO. Documents submitted may be considered in the examination of that patent application. In addition, these submissions have a broad impact because applicants have a duty to disclose the prior art submitted against a single patent application for other relevant patent applications filed by the applicant.

Porta Sophia tracks and analyzes psychedelic patent applications globally. If an application improperly claims innovation of something known in the public domain and meets the standards of Porta Sophia's third party intervention evaluation criteria, the team assembles evidence against these invalid claims and contests them directly to the relevant patent office through third-party interventions.
