US Patent & Trademark Office Issues Guidance for Trademarking CBD Products

By Aaron G. Biros

Last week, the United States Patent and Trademark Office (USPTO) published an Examination Guide to provide further clarity for how they assess the legitimacy of trademarks for cannabis products. For the uninitiated, the 2018 Farm Bill, which President Trump signed into law on December 20, 2018, removed hemp-derived cannabidiol (CBD) from the Controlled Substances Act. In order to register a trademark in the United States, the mark must be used in a lawful setting, meaning that the USPTO does not register trademarks for products that violate federal law- even if it is legal under state law.

In their guidance document, the USPTO identifies the distinction between hemp and other cannabis varieties as the basis for either issuing or refusing a trademark registration. This means that in the trademark application, companies need to specify that the cannabis product is derived from hemp, or cannabis with less than 0.3% THC in dry weight.

The USPTO clarifies that applications for trademarks that involve CBD filed before December 20, 2018 will be refused, but if they amend the filing date to after that date, the registration will be examined. Below is a direct quote from their examination guide clarifying this:

For applications filed before December 20, 2018 that identify goods encompassing CBD or other cannabis products, registration will be refused due to the unlawful use or lack of bona fide intent to use in lawful commerce under the CSA. Such applications did not have a valid basis to support registration at the time of filing because the goods violated federal law. However, because of the enactment of the 2018 Farm Bill, the goods are now potentially lawful if they are derived from “hemp” (i.e., contain less than 0.3% THC). Therefore, the examining attorney will provide such applicants the option of amending the filing date and filing basis of the application to overcome the CSA as a ground of refusal.

The USPTO’s Examination Guide explicitly mentions the authority of the FDA to regulate products derived from cannabis, much like the 2018 Farm Bill’s language. There is still some confusion in the cannabis industry surrounding the marketing and sale of hemp products under FDA regulation.

Under the Federal Food Drug and Cosmetic Act (FDCA), using a drug in a food or dietary supplement that is currently undergoing clinical trials is illegal (as is the case here- see Epidiolex for an example of CBD being used as an active ingredient in an FDA-approved clinical trial). According to the USPTO, this means that “registration of marks for foods, beverages, dietary supplements, or pet treats containing CBD will still be refused as unlawful under the FDCA, even if derived from hemp, as such goods may not be introduced lawfully into interstate commerce.”

Regarding trademarks for services involving “cannabis and cannabis production,” the USPTO also issued guidance. This section of the Examination Guide pertains to companies applying for a trademark that fall in the category of ancillary services, such as growing supply companies, lighting, nutrients, pest control and packaging, among other service providers. Basically, this section boils down to the same distinction the Farm Bill made between hemp and other varieties of cannabis. An applicant for a trademark needs to make clear their identification of services offered as involving cannabis containing less than 0.3% THC.

For a helpful guide breaking down what this means for cannabis companies pursuing a trademark registration, Christiane Schuman Campbell, partner at Duane Morris LLP, published this client alert about the USPTO’s examination guide.

Here Comes The Start-Up Nation Of Cannabis: Israel

By Marguerite Arnold

No Comments

For those who have been watching (if not in the thick of) the drama over Israeli medical cannabis export rights, this latest development was not only inevitable but overdue. Israel’s parliament unanimously approved the legislation on Christmas Day (along with Thailand). Less than a month later, the cabinet concurred.

That means that export rights are now actionable law.

Beyond this final passage into reality, export rights have been at the forefront of a global drama on cannabis- most recently in this part of the world, as a specific chip in political dealmaking between U.S. President and Israel’s Prime Minister, Benjamin Netanyahu since the former entered office. This go around at least.

The political bargaining that even allowed Israel’s medical program to flourish and get funding from its earliest days (including of the U.S. federal government kind) of course, is nothing new.

Pioneers Of The Cannabis Industry

Hard as it is to believe, most of what is widely known and easily digitally shared (including on social media) about cannabis (as a plant, let alone distinctions between cannabinoids) is information created during this last four to eight-year period (certainly since 2010). This has been driven by reform, and a birth of wider education about medical and recreational cannabis plus the cannabis industry and broader lifestyle press. And most of what is credible out there, no matter who claims credit today, has an Israeli origin, and of the medical kind.

Add this history of scientific research and insight to the philosophy of a nation driven by entrepreneurial zest, and say no more.

Now that Israel can begin to export its cannabis, the interesting thing to see is whether cannatech will in the end, be more valuable than individual strains themselves. The pick axe in this particular “green gold rush?”

For now, of course, all bets are off, even on the cultivation front. Because, no matter what else it is, it is well timed, globally, to give even the Israeli medical production market a big green shot in the arm.

Germany and Europe Beckons

The change in the law in Israel also comes as those who made first qualifying round in the German cultivation bid are getting prequalification letters, although this time, no firms, anywhere, have issued press releases about their finalist round status.

And here is the other issue to consider: While the bid itself does not have anything to do with import capability, new Israeli game in town is, in itself, a big game changer for anyone whose hat was thrown into the coalitions who applied for the pending cultivation license. Why? Until they deliver their first crops grown auf Deutschland, firms have to deliver from somewhere. And this being Germany, the import destination has to be from a place where the plant is federally legal. Israel becomes another option in a market so far dominated by Dutch and Canadian firms.

Can you smell new bid lawsuits also, if this scenario has not already been addressed by BfArM? The history of cannabinoids in Germany in general (historically as well as recently) is fraught already. This pending challenge, should it come, will be laden with symbology modern Germany will do everything to avoid provoking.

Beyond the soap opera that the bid has turned into in Germany (the ultimate test case for cultivation and insurance-backed medical and industry acceptance across the rest of the EU essentially), there are of course, other markets beckoning. This includes all of Eastern Europe and much of the EU. This includes France and the UK immediately.

In other words, no matter what the longer-term impacts will be, this well timed, politically astute Israeli decision is coming at the beginning of what is going to be, as everyone is clearly seeing at the end of January, a momentous and earth-shaking year not only for Europe, but globally.

And that is big business for a little country with an eye on the export game.

First Cannabis Clinical Trials All Set In UK

By Marguerite Arnold

1 Comment

Beckley Canopy Therapeutics, based in Oxford, England has raised ₤7.4 million for the purposes of cannabinoid research and drug development. The new company is a unique partnership established between Canopy Growth Corporation and the Beckley Foundation, a research institute which examines the utilization of psychotropic drugs for the treatment of physical and mental conditions.

Studies focusing on the use of cannabinoids for the treatment of opioid addiction and cancer pain will be conducted in Europe, the UK and the US.

Why Is This Significant?

Here is the first reason: the woman behind it all. Her name is Lady Amanda Feilding, Countess of Wemyss and March. Born into a landed gentry family at Beckley Park (a Tudor hunting lodge with three towers and three moats) she also has a long history of engaging and supporting scientific endeavours that use stigmatized drugs in the treatment of both intractable disease and mental illness via the use of scientific research.

In 1998, Amanda Feilding set up the Beckley Foundation, a charitable trust which initiates, directs and supports neuroscientific and clinical research into the effects of psychoactive substances. She has also co-authored over 50 scientific papers in peer-reviewed journals.

The so-called “hidden hand” behind the rebirth of psychedelic science, Fielding’s contribution to global drug policy reform has been widely acknowledged in international drug policy circles. She was named as one of the bravest men and women in the history of science in 2010 by the British Guardian.

And here is the second reason: The foundation is now partnered with Canopy Cannabis, one of the leading cannabis firms in the world, which is also working closely with Spanish opioid manufacturer Alcaliber.

In other words, this coalition is almost the mirror opposite of the approach taken by the American Sackler family, makers of Oxycontin, who have fought cannabinoids as an alternative or even transition drug in multiple state legalization campaigns. Meanwhile the death rates from overdoses have quadrupled since 1999. In 2016, opioid-related drug overdoses killed about 116 people a day (or about 42,249 for the year). It is estimated that about 11 million people in the U.S. are currently misusing or dependent on opioids.

Beyond The Politics of The Opioid-Cannabinoid War

While opioids clearly have a role particularly in chronic pain treatment, the question now at the global scientific table is this: Are cannabinoids a substitute for longer term chronic pain management? It is a fiercely battled scientific debate that has frequently, particularly in the U.S., crossed over into political drug reform questions.

The unique partnership of Beckley and Canopy is well placed both scientifically and culturally to take on a discussion which has languished for too long in the grass of political debate and reform.

Even better, it is taking place in a country where English is the first language, but outside the U.S. and further, in a country where cannabis has now been legally reclassified as a Schedule II drug.

Do not expect, in other words, the same trials and tribulations that faced noted U.S.-based researcher Sue Sisley, to slow down research, trials or findings.

Why Is A Cultural and Scientific Reset Required?

For the past forty years, since the end of the 1970s, cannabis in particular, has been pushed into a strange scientific territory in part, because of the culture surrounding the drug. This in turn, along with the schedule I classification of cannabis, has led to not only a dearth of research, but a reluctance on the part of prescribing doctors to examine its efficacy.

In the present, this means that doctors are still (beyond insurers who demand medical evidence before approving payment) the biggest hurdles in every medical system where cannabis is becoming legal. See the debate in Canada, the UK and of course, Germany, where patients frequently report asking for a drug their doctors refuse to prescribe.

This is exactly the kind of high-placed, societally influential effort in other words, that might finally break the medical taboo at the most important remaining logjam– at the point of prescription and approval for patients.

FDA Approves GW Pharma’s Epidiolex

By Aaron G. Biros

No Comments

According to a press release, the U.S. Food and Drug Administration (FDA) approved GW Pharma’s drug Epidiolex for the treatment of rare forms of epilepsy. Just a few months ago, news broke of a very encouraging FDA panel assessment, which indicated a positive outlook for the drug’s approval.

In the press release, FDA Commissioner Scott Gottlieb, M.D appeared to indicate an open willingness to explore the medical benefits of cannabis. “This approval serves as a reminder that advancing sound development programs that properly evaluate active ingredients contained in marijuana can lead to important medical therapies,” says Gottlieb. “And, the FDA is committed to this kind of careful scientific research and drug development.” He went on to add:

Controlled clinical trials testing the safety and efficacy of a drug, along with careful review through the FDA’s drug approval process, is the most appropriate way to bring marijuana-derived treatments to patients. Because of the adequate and well-controlled clinical studies that supported this approval, prescribers can have confidence in the drug’s uniform strength and consistent delivery that support appropriate dosing needed for treating patients with these complex and serious epilepsy syndromes. We’ll continue to support rigorous scientific research on the potential medical uses of marijuana-derived products and work with product developers who are interested in bringing patients safe and effective, high quality products. But, at the same time, we are prepared to take action when we see the illegal marketing of CBD-containing products with serious, unproven medical claims. Marketing unapproved products, with uncertain dosages and formulations can keep patients from accessing appropriate, recognized therapies to treat serious and even fatal diseases.

According to the press release, the drug was studied in three randomized, double-blind, placebo-controlled clinical trials with 516 patients who have either Lennox-Gastaut syndrome or Dravet syndrome, the two rare forms of epilepsy the drug is now approved to treat. Epidiolex is an anti-epilepsy drug, taken in a syrup form, with the main active ingredient being cannabidiol (CBD), and less than 0.1 % THC.

Replacing Opiates with Cannabis is Finally Becoming a Reality: Where do we go from Here?

By Dr. Richard Kaufman

No Comments

Opiate abuse is a far-reaching international public health issue, impacting tens of thousands of people every year in the United States alone. As the epidemic continues to spread, the medical community is faced with the immense task of researching and developing safer, non-addictive treatment alternatives for patients of chronic pain and other ailments. The controversial and oft-debated notion of cannabis as an opiate alternative has become increasingly well-researched and gained considerable credibility in recent years. The new challenge lies in advancing the cannabis industry to the point of being a legitimate medicine that can be prescribed and administered by doctors.

Opioids are among the most commonly prescribed medical treatments for severe chronic pain, yet prescription opioid overdoses killed more than 165,000 Americans between 1999 and 2014 according to the Department of Health and Human Services. In fact, the health and social costs of opioids are estimated to be as much as $55 billion a year. As such, it has become more imperative than ever that mainstream medical practitioners take notice of the cannabis plant’s powerful healing properties and shift away from potentially harmful pharmaceutical medications.

The evidence of cannabis’ safety and efficacy is well established. For instance, in a literature review of 38 studies evaluating medical cannabis’ efficacy for treating pain, 71 percent concluded that cannabinoids had empirically demonstrable and statistically significant pain-relieving effects. In addition, a 2015 meta-analysis of 79 studies found a 30 percent or greater reduction of pain with the use of cannabinoids compared to placebos. Further, an analysis of a decade of randomized, double-blind placebo-controlled clinical trials on cannabis for treating pain concluded that cannabis should be a first line treatment for patients with painful neuropathy and other serious and debilitating symptoms, who often do not respond to other available medications.

Not only is cannabis demonstrably safe and effective, but numerous studies also present compelling evidence that the prescription of opiates has dropped sharply in U.S. states and countries that have legalized medical cannabis. For example, a study in the Clinical Journal of Pain followed 176 chronic pain patients in Israel over seven months. Researchers found that 44 percent of participants stopped taking prescription opioids within seven months after starting medical cannabis. Patients cited the following reasons for using cannabis instead of pharmaceutical drugs: 65 percent reported less adverse side effects, 57 percent cited better symptom management and 34 percent found that cannabis had less withdrawal potential than their other medications.The evidence of cannabis’ safety and efficacy is well established.

The tide is quickly turning as many respected doctors are beginning to advocate for the tremendous medical potential of cannabis as a replacement for prescription pills. That said, if the cannabis industry is to help solve the crisis inflicted by modern pharmaceutical painkillers, we must develop next-generation scientifically formulated products and advocate to improve their accessibility.

Inhalation and oral methods of cannabis consumption have no reliable dosage as medicine, rendering them unfit for administration by health professionals. These mainstream consumption methods also have extremely low bioavailability and bioactivity. Bioavailability for ingested cannabis products is only 6 percent and for inhalation methods can be as low as 2 percent. Oral absorption of THC is slow and unpredictable, with peak blood concentration occurring 1–5 hours post dose. Similarly, inhalation methods can take up to two hours to have any effect. The next phase of the medical cannabis industry must focus on fixing problems that prevent cannabis from being a universally recognized health tool. Fortunately, scientists are making major advancements in cannabis delivery technologies, offering novel and innovative administration methods that have proven both effective and reliable.

With products like Evolve’s NanoSerum™ representing a promising solution to help reduce the morbidity and mortality associated with prescription opioid use and abuse, meaningful progress is already underway. It’s been a long and challenging road to arrive at this point, but our efforts are only just beginning. Achieving long-term change on a national and international scale will require professionals from all levels of the cannabis, science and medical communities to push for advanced product offerings that provide consistent, standardized dosing in healthier, smokeless modes of delivery.

Shimadzu, Cure And CK Sciences Partner On R&D of Pharmaceutical Cannabis Products

By Aaron G. Biros

1 Comment

Yesterday, Shimadzu announced the formation of a partnership with Cure Pharmaceutical Group and CK Sciences to research and develop pharmaceutical cannabis-based products, according to a press release. The three organizations entered a collaborative agreement with the goal of researching and developing products, then moving them through clinical trials using FDA guidelines.

According to the press release, the partnership’s primary goal will be researching and profiling the synergistic effects of the cannabinoids and terpenes, called the “Entourage Effect.”

Shimadzu, a well-know analytical instrument manufacturer, has been making a name for itself in the scientific cannabis space with a number of exciting new ventures. They have worked extensively with cannabis laboratories throughout the country in refining methods and improving analytical chemistry in the space. For example, Shimadzu powers EVIO Labs Florida with over $1.2 million in the latest testing instrumentation.

Tracy Ryan, chief executive officer and founder of CK Sciences, says outfitting their lab for pharmaceutical research was a big priority for starting their venture. “When we met with Shimadzu, and we saw their passion for our mission, we knew we were in incredible hands! When analyzing cannabis everything has to be so precise,” says Ryan. “With Shimadzu’s platforms and team of brilliant scientists supporting our efforts, we have already set ourselves up for success.”

Back in March, Shimadzu launched their Cannabis Analyzer for Potency, a high-performance liquid chromatograph (HPLC) designed specifically for quantitative determination of cannabinoid content. The organizations in the partnership will be using that instrument, in addition to a headspace Gas Chromatograph Mass Spectrometer (GCMS) for terpene profiling. Both Cure and CK will use the instruments to generate data, with the goal to validate cannabis as a viable pharmaceutical treatment, according to the press release.

Bob Clifford, Ph.D., general manager of marketing for Shimadzu, says they are excited to work with the organizations. “The emerging pharmaceutical cannabis market requires dedicated, thoughtful leaders eager to showcase the pharmaceutical benefits of cannabis on a scientific level,” says Clifford. “The Cure/CK Sciences group has continuously demonstrated such a leadership commitment, and we’re excited about the opportunities this agreement provides.”

Steep Hill Labs Expands to Pennsylvania, Washington, D.C.

By Aaron G. Biros

No Comments

Last week, Steep Hill Labs, Inc. announced plans to expand on the East Coast, including licensing for laboratories in Washington, D.C. and Pennsylvania. The cannabis testing company now is operating or developing in seven states, the District of Columbia along with an official arrangement with a research university in Jamaica, according to Cathie Bennett Warner, director of public relations at Steep Hill.

The same team of physicians that oversees the Steep Hill laboratory in Maryland will operate the Pennsylvania and D.C. labs. Heading that team is chief executive officer Dr. Andrew Rosenstein, chief of the division of Gastroenterology at University of Maryland Saint Joseph Medical Center and assistant clinical professor of Gastroenterology and Hepatology at the University of Maryland Medical Center. Dr. Rosenstein has been recognized by Baltimore Magazine as a top doctor in the Baltimore area, according to a press release.

Dr. Andrew Rosenstein, CEO of Steep Hill Maryland, PA and D.C.

According to Dr. Rosenstein, they want to provide accurate clinical results for trials with patients using cannabis. “All clinical trials will require a competent, credible and reliable lab partner and that is what we are bringing to the field- and that is why we are working with Steep Hill,” says Dr. Rosenstein. With team members having backgrounds in pathology, molecular diagnostics, clinical chemistry, microbiology and genetics, it should come as no surprise that they plan to participate in clinical research.

Dr. Rosenstein’s vested interest in cannabis safety stems from prior experience with his patients using cannabis. “Over the past five years, we have seen an increased number of patients using cannabis, particularly for managing the side effects of Crohn’s disease and cancer treatment,” says Dr. Rosenstein. “They would bring it up to us and at the time I didn’t know much about it, but anecdotally it’s really clear that a lot of patients have great responses to it.” Not knowing much about the preparation or safety of cannabis at the time led Dr. Rosenstein to advise patients to be very careful if they are immunocompromised.

“When a patient is immunocompromised, a bacterial or fungal infection can be lethal, so because we had patients using cannabis, we wanted to make sure it was safe,” says Dr. Rosenstein. So when Maryland legalized medical cannabis, Dr. Rosenstein and his team saw the need to protect patient safety and Steep Hill was a perfect fit. “We really didn’t want to reinvent the wheel so we looked for someone to partner with,” says Dr. Rosenstein. “Steep Hill has the best technology and the best credibility and we didn’t want to compromise on quality and safety issues. They felt the same way so we partnered with them and culturally it has been a great fit.”

The new laboratories plan to offer a similar range of services that are offered at other Steep Hill labs, such as rapid potency testing for THC-A, ∆-9-THC, CBD, CBD-A and moisture. But Dr. Rosenstein sees clinical opportunities in the East Coast medical hubs. “We want to provide the testing component for studies, providing clinical reproducibility and consistency, and those are the things as a top-notch lab that we are interested in doing.”

With a physician-led group that has experience in molecular diagnostics, partnering with Steep Hill is about being medically focused, according to Dr. Rosenstein. “First and foremost, this is about patient safety.” Because of that, he emphasizes the need for required microbiological contaminant testing, particularly because of his experience with patients. “If you’re a cancer patient and you get a toxic dose of salmonella or E. coli, that can kill you, so testing for microbiologic contamination is of the highest priority.”

According to Warner, bridging the medical cannabis science gap with Steep Hill’s professionalism and experienced doctors practicing medicine is a big deal. “We are working very closely with their medical team to make sure these standards are medically superior,” says Warner. “To have these doctors with such a high level of knowledge in medicine working with us in cannabis analytics is a breakthrough.”
