U.S. patent application number 15/924,172 "Electronic Vaporizer with Remote Control Capability" was issued a Notice of Allowance by the USPTO on February 9, 2022. A Notice of Allowance is a document sent to a patent applicant from the USPTO after a patent examiner has decided to issue the requested patent and is the final step in a usually long and complex patent application process.

The RYAH Smart Medical Inhaler is a hybrid conduction and convection, style dry herb inhaler and was recently granted Medical Device Certification under ISO 13485:2016/MDSAP and EN ISO 13485:2016 standards for both its hardware and software. The connected device contains an integrated volumetric airflow sensor that enables consumers to easily track their therapeutic inhalation sessions. The system's precise temperature and volume session monitoring, combined with complete formulation lab results and intuitive user session feedback, drives its state of the art, anonymized data aggregation analytics.
