Porta Sophia Files Third-Party Preissuance Submission for CLEARMIND MEDICINE INC. U.S. Patent Application 18/699,185

Psychedelic prior art library presents four documents challenging patentability of all 21 claims

MADISON, WI USA (June 12, 2025) 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. 18/699,185 entitled “5-MAPB OR 6-APB FOR USE IN DRUG-ASSISTED PSYCHOTHERAPY”, which is currently assigned to CLEARMIND MEDICINE INC. The submission consisted of four prior art documents that are material to the patentability of all 21 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: 5-MAPB and 6-APB for MDMA-resistant patients in psychotherapy

The ’185 application was filed on April 5, 2024. It describes methods of treating individuals resistant to MDMA-assisted therapy using 5-MAPB or 6-APB, with administration timed before, during, or after a psychotherapeutic intervention. Filed as a broad therapeutic framework, the invention targets distress-related conditions, especially trauma-linked disorders such as PTSD, anxiety, bipolar disorder, and substance use disorders. The claims cover a dose range of 50–500 mg per session for the reduction of cognitive, emotional, and relational distress. A kit including administration guidelines for use alongside various psychotherapeutic modalities (e.g., humanistic or integrative therapy) is also claimed.

Prior art in the third-party preissuance submission included a peer reviewed journal articles, an online report, and a U.S. patent document. This prior art anticipates claims in the ’185 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.
