When is the next marijuana patent?

A patent list from the US Patent and Trademark Office, published on Thursday, shows that at least four companies are actively filing applications for the first time in the patent wars.

The first batch of patents, from Marihuana for Medical Purposes Regulations (MMPR) applicants, include a proposal for a “plant-based food that is more stable than foods made with animal proteins”.

The application was filed by New Zealand-based biotech firm Rethink Foods, and its website says the company wants to use cannabis oil to reduce pain, improve appetite, reduce anxiety, and boost cognitive function.

A similar application filed in August by the cannabis product company Indivisib claims the invention could treat the chronic pain of multiple sclerosis (MS). 

Another application from the UK-based company Tweed Marijuana was filed in October, but was not linked to the US patent.

Another application, by cannabis product firm Cannabidiol, is currently awaiting review.

Two more applications were filed in November by California-based cannabis oil company BioMarinol.

They describe the use of cannabidol to treat epilepsy and neurodegenerative diseases, and are the first to use an industrial hemp-based product to make medical marijuana.

These patents are only a small sample of the patent activity on the USPTO’s patent filing list.

In the meantime, the USPs website says, “patents are being issued in the most unusual and unusual places”.
