FTO Files PGR Petition on a Second Compass Patent
Update December 22, 2021
A comprehensive, peer-reviewed study was just published on the crystal structures of psilocybin. The work entailed intensive computational modeling as well as the use of a synchrotron at Argonne National Laboratory to get high-resolution diffractograms of several samples of crystalline psilocybin. Historical samples analyzed included Sandoz material almost six decades old.
Vice.com ran an article about a USPTO petition recently filed for a post-grant review of a Compass patent, based on the new scientific findings: “The non-profit Freedom to Operate used research from chemists and crystallographers to argue in a legal filing that Compass’ form of synthetic psilocybin is not a new invention.”
FTO filed another such PGR, Wednesday, Dec. 22, challenging a second Compass patent.
From the paper’s press release:
- Over the last 57 years, each of the historical samples quantitively reflect one or more of the three repeatedly observed crystalline forms of psilocybin.
- Modern analysis of crystallographic research with psilocybin published in the 1970’s reveals the three predominant crystalline forms were described and publicly available for decades.
- Unusual characterization data originally reported to be unique were exposed instead as a simple mixture of the known polymorphs.
Revisions are recommended on characterizations in recently granted patents that include descriptions of crystalline psilocybin mixtures inappropriately reported as a novel variant.
- Crystallization experiments show how to precisely control and obtain each polymorph individually and how to avoid undesirable mixtures in large-scale manufacturing.
Congratulations and thanks to the scientists at Usona and the consulting scientists who were able to complete this very specialized work, and to those who supported the project financially through Freedom to Operate.

Crystallographic Discoveries Bring New Clarity to Pharmaceutical Psilocybin Polymorph Characterization
Update December 21, 2021
“FTO was seminal in both the conception and the eventual creation of, this important paper and its conclusive peer-reviewed science. Everyone who will benefit from the clinical use of psilocybin owes a great debt to the credentialed scientists who did this work.”
Carey Turnbull, Executive Director, Freedom to Operate, Inc.
Peer-reviewed study out today shows three most pharmaceutically relevant crystalline forms of psilocybin have been consistently created and observed since 1959.
FTO’s PGR Petition Filing Milestone
Update December 16, 2021
Freedom to Operate filed yesterday a petition for Post Grant Review of Compass patent number 10,947,257 at the USPTO. The PGR Petition explains that Compass’s patent claims, directed to an oral dosage form containing its “Polymorph A” psilocybin and an excipient called silicified microcrystalline cellulose, are invalid for a number of reasons. The Petition and the expert declarations filed with it from Dr. Sven Lidin and Dr. James Kaduk explain that “Polymorph A” is a mixture of known psilocybin polymorphs, not a new polymorph as claimed. Compass’s patent is therefore invalid as claiming a nonexistent polymorph, and also obvious in light of prior art samples of psilocybin and previous clinical studies teaching the use of psilocybin to treat depression. Compass’s patent is also invalid because it does not explain how to determine the claimed characteristics of the psilocybin and SMCC in the claimed oral dosage form.
Freedom to Operate, Inc. filed this petition to further its mission to challenge mistakenly issued patents, in particular in the widely researched psychedelic space. Gathering the evidence supporting the Petition and preparing and filing it required several years and close to a million dollars in funding on the part of FTO. In the course of its work, FTO and its research collaborators identified a dozen or so sources of psilocybin with sufficient forensic provenance, many predating the Compass patent, that was extensively analyzed and tested. The production of hard science by world-class chemists and crystallographers used state-of-the-art X-ray powder diffraction, including crystallography analysis done on the synchrotron at Argonne National Laboratory, a multidisciplinary science and engineering research center that works in concert with universities, industry, and other national laboratories on questions and experiments too large for any one institution to do by itself. A psilocybin sample was obtained from the US Government National Institute of Drug Abuse, which was determined to be original Sandoz material dating from 1963, and others were obtained from several Universities and research institutions well known for their work on psilocybin for decades. The sample most extensively used to document the preexistence of the well-known anhydrous polymorph was made by renowned psychopharmacologist and founder of Heffter Research Institute Dave Nichols, and had been supplied to the prolific Johns Hopkins University psilocybin research lab of Roland Griffiths.
FTO founder and Executive Director Carey Turnbull said “I want to thank the chemists and crystallographers who worked on this project and who are named in the filings and publications for their perseverance and hard work. In addition, we owe a debt to the vision, patience, and generosity of Bill Linton, The Steve and Alexandra Cohen Foundation, Evolve Foundation, Bronner’s Soaps, and others without whose gifts, in addition to those from Claudia Turnbull on behalf of my family foundation, this important work would not have been possible.”
UK IP Office Opinion in Response to FTO Request
Update July 28, 2021
“Just this week, the United Kingdom Intellectual Property Office issued an Opinion regarding a Compass patent directed to its so-called “Polymorph A”. That Opinion was issued in response to a request by Freedom to Operate asking the UK IP Office to consider the validity of the patent in light of prior scientific publications, particularly an article by Dr. Folen in the Journal of Forensic Science and by well-known psychedelic chemist Dr. David Nichols. The Opinion found that many of the claims of the Compass patent were not inventive, including the broadest claim directed to its “Polymorph A”, in light of these publications.
The new UK Opinion is from a knowledgeable UK patent examiner and supports FTO’s position that there can be no valid patent on the known forms of psilocybin. Patents in the psychedelic space should be carefully limited to only truly new inventions. The Opinion is publicly available and can be downloaded here. FTO is committed to defending the right of the public to use the various forms of synthetic psilocybin made for many years and used by researchers in human clinical trials well before Compass filed its patent applications. FTO’s research strongly suggests that Compass did not discover any new crystal forms of psilocybin in the course of conducting its scale-up research.”
