MADISON, WI USA (July 5, 2023) Porta Sophia filed a third party observation with the World Intellectual Property Organization (WIPO) today for the international patent application PCT/US2022/043580 entitled “Chewing Gum Formation of LSD and Methods of Use Thereof”, which is currently assigned to Eleusis Therapeutics US Inc. The submission consisted of six prior art documents that are material to the patentability of all 46 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: LSD formulated in chewing gum
The PCT application was filed on September 15, 2022 and claims priority to a U.S. provisional application filed on September 15, 2021. It describes a method of formulating LSD in chewing gum and using this formulation to treat Alzheimer’s Disease and its symptoms.
Prior art in the third party observation included publications from peer reviewed journals, web pages, and international patent documents. This prior art anticipates claims lacking novelty in the PCT application. A full claims chart and corresponding prior art is available here.
Third party submissions of prior art
WIPO Patent Cooperation Treaty guidelines allow third parties to submit prior art and concise descriptions of their relevance to the WIPO. This ensures that the documents submitted will 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.
