It may come as no surprise that with the rise of interest in the new psychoactive cannabinoid derived from hemp, Hexahydrocannabinol (HHC), it has many people looking to invent new methods to extract it from the hemp plant. When you look online, you’ll find many resources for Hexahydrocannabinol (HHC) Patents, and we want to take a moment to go through what is included in those patents.

US9694040B2 – Hydrogenation of cannabis oil

One of the first patents you might discover is the Hydrogenation of cannabis oil. In the abstract for the HHC patent, it provides the following:

The invention includes hydrogenated cannabis compounds and compositions, as well as methods of preparation and therapeutic uses for regressing tumors in a cancer patient.

In the background section of the patent application, it provides the following:

In general, hexahydrocannabanoids (HHCs) have been demonstrated to be anticancer compounds that inhibit cell proliferation and tumor angiogenesis (Eur J Pharmacol. 2011 650(1):64-71). The anti-tumor activity of the hexahydrocannabinol analog LYR-8 in human colorectal tumor xenograft is mediated through the inhibition of Akt and hypoxia-inducible factor-1α activation. HHC compounds have been prepared by various methods, including the methods described in U.S. Patent Application Publication 2010/0298579 A1…

Within the detailed description of the patent, it provides the following information:

Hexahydrocannabanoids (HHCs) can be produced by hydrogenating mixtures of tetrahydrocannabanoid compounds, the principal component of the essential oil from cannabis plants, herein referred to as cannabis oil. Cannabis oil can be obtained from plants of the Cannabis sativa, C. indica and C. ruderalis by various conventional isolation processes, including steam distillation, organic solvent extraction, microwave-assisted organic solvent extraction, supercritical fluid extraction and cryo-mechanical methods. The crude cannabis oil, extract or concentrate obtained from these processes can be used without any purification to produce HHC-enriched cannabis oil by hydrogenation of the oil directly to reduce the carbon-carbon double bonds of the tetrahydrocannabinoid compounds in the oil such as Δ-9-tetrahydrocannabinoic acid (THCA) and Δ-9-cannabidioc acid (CBDA).

In 2019, the patent was awarded to Research Grow Labs and the patent is anticipated to expire in the year 2036. A similar patent in Canada has also been filed.
