Cannabis Patent Review: Extraction and Purification

In this first article of his Cannabis Patent Review series, Duane Morris partner Vince Capuano reports on the patenting of technology related to cannabis extraction and cannabinoid purifications.

He writes:

One of the more active areas in the patenting of cannabis technology in 2019 is the related fields of cannabis extraction and cannabinoid purification.  Cannabis operators now must educate themselves and navigate an emerging landscape of U.S. cannabis extraction and purification patents for freedom to operate, while also looking for opportunities to patent their own innovations. So far in 2019, the U.S. Patent and Trademark Office (USPTO) has granted over 30 patents with claims directed to cannabis extraction technologies and many others related to distillation of cannabinoid components and techniques for obtaining active compounds from marijuana and hemp. Dozens more are pending.

Duane Morris Partner Vince Capuano Quoted in AP News Article, “How much pot in that brownie?”

How much marijuana is really in that pot brownie? Chocolate can throw off potency tests so labels aren’t always accurate, and now scientists are trying to figure out why.

In states where marijuana is legal, pot comes in cookies, mints, gummies, protein bars — even pretzels. These commercial products are labeled with the amount of high-inducing THC. That helps medical marijuana patients get the desired dose and other consumers attune their buzz.

But something about chocolate, chemists say, seems to interfere with potency testing. A chocolate labeled as 10 milligrams of THC could have far more and send someone to the emergency room with hallucinations.

Scores of cannabis-related inventions have received U.S. patents, said [Duane Morris partner] Vincent Capuano, who holds a doctorate in organic chemistry. Inventors have patented ways of putting cannabis into milk, coffee pods, ice pops and chewing gum.

“There’s a lot of flash and hipness, snake oil and marketing. But there’s still a lot of real chemical advance happening,” Capuano said of the industry. “It’s right in center field for chemists.”

“Sort of a Land Grab”: Intellectual Property in the Cannabis Space

Cannabis Wire discussed the Duane Morris webinar, Cannabis 202: IP Issues Facing the Cannabis Industry: Hot Topics in Patent, Trademark and Branding Protection and Enforcement.

The publication writes:

The 2018 Farm Bill, which legalized hemp in the U.S., has triggered an avalanche of applications for cannabis patents and trademarks.

Last Tuesday, Duane Morris, an international law firm headquartered in Philadelphia, hosted a webinar on intellectual property concerns as they relate to the cannabis industry. Early on, the presenters made two things clear: one, there is an unprecedented rush for cannabis patents, and two, how property rights in the industry will be divvied up remains up in the air. The lawyers presented a patent and trademark landscape that the industry needs to understand, but one in which the rules are very much in formation.

Case Sets Stage for Cannabis Patent Infringements Actions

Getting a patent for a cannabis product is no more difficult than getting a patent for any other kind of product. However, with a high number of cannabis patent applications being approved, it is likely that many will be challenged for invalidation in the coming years.

Already one of these patents has gone to court in the U.S. District Court for the District of Colorado. In United Cannabis v. Pure Hemp Collective, United Cannabis Corp. claims that Pure Hemp Collective Inc. used a cannabis extract that United Cannabis had a patent on. Pure Hemp filed a motion for partial summary judgment, arguing United Cannabis should not have had a patent on the extract because it was something that occurred naturally. In April, U.S. District Judge William Martinez found the strain was altered and would not have occurred naturally and denied the motion for partial summary judgment. The case is still pending..
