Note: The applications and patents in the table include all U.S. and PCT filings with substantive claims to psilocybin compositions, formulations, and methods of use or production. Applications or patents filed in other jurisdictions, or those where psilocybin is only referenced incidentally, are not included. Where a PCT application has already entered prosecution in the U.S., only the U.S. application is included. “Priority date” refers to the earliest filing date on which an applicant can rely (typically, the filing date of a U.S. provisional application); it is used to determine who filed first and what public information qualifies as prior art.
