"GW Pharmaceuticals announced Wednesday that it has been issued a Notice of Allowance from the U.S. Patent Office for a patent application involving the use of THC and CBD, the two main chemicals in marijuana, for treating gliomas.
Once a patent application is deemed a genuine invention, the Patent Office sends a Notice of Allowance that outlines the fees involved with final approval.
Specifically, the company provides this description of the patent:
However, it’s likely that the application was revised since then to be more specific in its claims, including the ratio of THC to CBD used and the type of cancer treated.
Indeed, the use of cannabis and cannabis-derived chemicals to fight a wide range of cancers has long been suggested by pre-clinical research as well as anecdotal reports.
On the other hand, the first clinical trial to investigate these cancer treatments only began last month, launched by GW Pharmaceuticals for their cannabis drug Sativex.
The trial investigates Sativex in combination with the standard chemotherapy drug temozolomide, and involves 20 patients with recurrent glioblastoma multiforme (GBM), an aggressive and rare form of brain cancer.
GW Pharmaceuticals also announced in November that it had begun human trials of a CBD-rich cannabis drug for the treatment of pediatric epilepsy."

"London, UK, 11 December 2013: GW Pharmaceuticals plc (Nasdaq: GWPH, AIM: GWP, "GW" or the “Company”), a biopharmaceutical company focused on discovering, developing and commercializing novel therapeutics from its proprietary cannabinoid product platform, announced that the United States Patent and Trademark Office (USPTO) has issued a Notice of Allowance for U.S. Application Serial Number 12/996,124, a patent which covers the use of cannabinoids for treating glioma. Glioma describes any tumor that arises from the glial tissue of the brain. Glioblastoma, or GBM,
is a particularly aggressive tumor that forms from abnormal growth of glial tissue. According to the New England Journal of Medicine, GBM accounts for approximately 46% of the 22,500 new cases of brain cancer diagnosed in the United States each year. Treatment options are limited and expected survival is a little over one year. GBM is considered a rare disease by the FDA and the European Medicines Agency, or EMA.
The subject patent specifically covers a method for treating glioma in a human using a combination of cannabidiol (CBD) and tetrahydrocannabinol (THC) wherein the cannabinoids are in a ratio of from 1:1 to 1:20 (THC:CBD) with the intent to reduce cell viability, inhibit cell growth or reduce tumor volume. A Notice of Allowance is issued after the USPTO makes a determination that a patent can be granted from an application. The issued patent from this application will provide an exclusivity period until June 2029.
“This Notice of Allowance follows the recent launch of our first human trials in glioma and several years of pre-clinical research in the field,” stated Justin Gover, GW’s Chief Executive Officer. “The treatment of Glioma is part of our exciting new orphan drug program which includes a number of therapeutic targets and demonstrates the flexibility of GW’s proprietary cannabinoid platform in treating a broad range of disease types.”
GW’s intellectual property portfolio includes multiple patent families with issued and/or pending claims directed to plants, plant extracts, extraction technology, pharmaceutical formulations, drug delivery and the therapeutic uses of cannabinoids, as well as plant variety rights, know-how and trade secrets."

Filed in 2009, GW’s patent application lists Otsuka Pharmaceutical as a collaborator and initially claimed the invention of the “use of a combination of cannabinoids in the manufacture of a medicament for use in the treatment of cancer.”
However, it’s likely that the application was revised since then to be more specific in its claims, including the ratio of THC to CBD used and the type of cancer treated.
