GW Pharmaceutical Company Receives CBD Patent As Cancer Cure

A drug maker will soon hold patent on THC CBD treatment.

GW Pharmaceutical receives early approval on patent covering marijuana chemical

GW Pharmaceutical CBD Cancer Cure Patent – Medical Marijuana 411 – Drug maker will soon hold patent on THC CBD treatment.GW Pharmaceuticals announced  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:

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.

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.

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.

    Nonsense headline. You cannot get a patent on natural chemicals. Learn how to write properly and not sensationalize.

    The patent is for a TREATMENT that uses both cbd and thc along with the standard chemotherapy drug to treat brain tumors… just because mcdonalds has a patent on the big mac doesnt mean they got the patent for cows…

    Another example of American government doing shady deals… Someone please tell these officials, CEOs, whomever wanting to get on the bandwagon , they can’t patent nature! Profiting on royalties or rights to this patent would be illegal… Any lawyers or judges out there??

    Patent Office bureaucrats do what they are fracking well told.
    Question is, when not if a patent is issued, who’s going to police
    medical weed consumption without being totally re-creative
    (=lying through back teeth) regarding alleged intentions of
    the medical user’s desired therapeutic outcome of the
    said consumption.
    Merck patented a therapeutically-effective niacin-CoQ10 combination.
    They in effect admitted criminality by shelving the patent to stop any
    competitor marketing such a great product.
    I don’t imagine the miserable Merck’s patent stopped any one ND
    prescribing their patient take Niacin and Co Q10 together, from
    different sources.

    chemotherapy is poison ….using cannabis oil alone and diet is all that’s needed to cure cancer

  16. Ray 2 years ago

    It’s not, their patent is for their proprietary blend of extracts. It doesn’t mean they own CBDs or THCs. It protects them from others who would try to patent something similar as a treatment for brain cancer. With all of that said, I think it’s BS too!! Now that cannabis has come into the mainstream the corporations want to have it all.

  17. Doc 2 years ago

    How can someone get a patent on chemicals that are produced naturally on earth? That’s like getting a patent for dirt.

    Bullshit. These are the same asses that have damned the evil demonic weed swearing the herb has no medicinal properties. No…not until the FDA and Pharmaceutical Companies can make their $$$$ on it. How many lives could have been saved if the lies and Propaganda had never been. Pisses me off to the MAX!!!

    Get ready for your cannabis access to be limited again – and get ready for $250,000 cannabis treatments. The average cancer patient costs are over a $Million – with treatments and staff care.

    Our grandfathers sold us off to “patent medicines” back in the 1920’s and 1930’s – along with miracle cannabis cures that no one can remember now. What a tragedy.

    FREE THE PLANT – END THE PROHIBITION. Force corporations to earn money the old-fashioned way and stop creating “managed markets” – their own brand of monopoly.

    The next step is to take away your access to essentials such as vitamins. STOP THEM NOW.

    GW is a frontrunner on cannabinoid research in the UK.

    This is a small pharma company. They are NOT the bad guys.

    Do some research before blindly pointing fingers like this is a bad thing.

    United States Patent: 8632825 Anti-tumoural effects of cannabinoid combinations
    The invention relates to the use of a combination of cannabinoids, particularly tetrahydrocannabinol (THC) and cannabidiol (CBD), in the manufacture of a medicament for use in the treatment of cancer. In particular the cancer to be treated is a brain tumor, more particularly a glioma, more particularly still a glioblastoma multiforme (GBM).

    Claim: A method for treating glioblastoma multiforme in a human in need thereof consisting essentially of administering to said human therapeutically effective amounts of cannabidiol (CBD) and tetrahydrocannabinol (THC) in combination as pure cannabinoids wherein the cannabinoids are in a ratio of from 1:1 to 1:20 (THC:CBD).

    United States Patent 8,632,825 Velasco Diez, et al.
    issued: January 21, 2014
    Assignee: GW Pharma Limited (Salisbury, GB)
    Otsuka Pharmaceutical Co., Limited (Tokyo, JP}

    TABLE-US-00002 TABLE 2 Tumour volume relative to zero time following 15 days of treatment
    Tumour volume
    Vehicle 9.2 .+-. 0.6
    Pure THC 5.1 .+-. 0.4
    THC extract 6.6 .+-. 0.3
    THC:CBD (1:1) extract 4.8 .+-. 0.3

    As can be observed in Table 2 above the tumour volume after treatment with the 1:1 combination of THC and CBD extracts is significantly superior to the treatment with either the pure THC or the THC extract alone.

    This data suggests that the cannabinoids THC and CBD would be more effective in the treatment of tumours when used in combination.

    Applying for a patent for a specific ratio for natural, herbal remedies is a bad thing, and there are no pharma corps in the world that put cures above profits. Besides the fact that it’s idiotic, as Burt pointed out above, the US govt preempts this patent application. That being said – the patent office is such a joke these days that they may well miss it. Patents should be for actual inventions, not recipes…

    I think you are engaging in more conceptual thought than they can understand. I mean, if they could get a patent on oxygen, they would start charging us for it. Especially, since it is a naturally occurring substance.

    i agree lady, this shit will end soon though so dont worry, ive been teling my family since i was really young that i read cannibus had this worth and i was always ignored. i cant wait til this information hits full blast on all the people ive been telling this to for the last five years. i have noticed they have slowly started figuring out the truth. and today my mom asked me about it. feeling good that i was telling people the truth and my mom huged me today and told me that this world truly has some promlems. finally broke through the ignorance

  26. Cyndi 2 years ago

    totally wrong. they are mixing this with chemo and calling patent on a plant. ONLY if they design a PARTICULAR PLANT should they be able to develop a patent on it. It is like saying air in the sea is better than mountains air, So we shall put a patent on sea air and charge others who live there to breathe it.

  27. Maggi 2 years ago

    If they are applying for anything more than their specific strains for specific conditions, I hope they will be quickly challenged in Court.

  28. Mathew 2 years ago

    They can patent it all they want, as long as we can still get it grown by caretakers they aren’t doing anything drastic. Private manufacturing of the plant and concentrates can be done in a way to manipulate the structure of the THC and CBD making it just different enough from the patent to not be what is patented therefore rendering their patent claims void if they attempt to enforce them, this is futile. Its like saying your going to patent maple syrup but there are 80 kinds of maple syrup and anyone with some botany training cane create their own syrup. This is just so they make money, but this won’t help them as long as the people continue to grow dank nugs from private stock. Every grower knows, even the best strands grow totally different by different growers making it like an entirely different plant.

  29. Andrew K Fletcher 2 years ago

    If it can be shown that there is prior publications that predate that of the patent proof of concept than the patent can be contested and revoked.

    This happened to the natural extract Colchicine used to alleviate gout and,it is derived from the autumn crocus. Ben Franklin who suffered from gout brought collchjcine to the Us from France.. In 2009 URL Pharma said, “Hey, this has never been approved by the FDA.” So they proved it worked, claimed it as a drug, raised the price 50 fold and now you can’t buy colchicine without a prescription. There is a huge underground market for it though. It splits the DNA in marijuana seeds to make super weed. Look it up.

  31. Aaron 2 years ago

    It actually happens all the time. What they patent in this case is the treatment specifics as in dosage of CBD and THC. Which then makes any extract product with that dosage legally theirs to sell. Other ways to patent a “natural” product is to patent an processing method, an altered gene sequence, or by trademarking a brand.

    now you see the truth revealed and there can be no doubt with this that your government is in bed with pharma corps – this comes weeks after the fed out of no where decide to lift the ban on medicinal pot… follow the money people I will bet you it goes from drug co CEOs all the way to the congress. oh wait any intelligent person already knows this…which also knows they knew this treatment was valid for a while and let people suffer needlessly criminally.
    This also means corporations which were using pot for testing were doing so illegally ( yes the ban was for any and all medical or testing of pot of any kind) and this basically gives them a pass on conviction that hundreds of thousands of Americans in jail for pot didn’t get. Ready to hang your government yet and replace them with people that realize America is a place where we have the right in our founding declaration to remove forcibly a corrupt government from office and replace them.
    “That whenever any Form of Government becomes destructive of these ends, it is the Right of the People to alter or to abolish it, and to institute new Government, laying its foundation on such principles and organizing its powers in such form, as to them shall seem most likely to effect their Safety and Happiness. Prudence, indeed, will dictate that Governments long established should not be changed for light and transient causes; and accordingly all experience hath shewn, that mankind are more disposed to suffer, while evils are sufferable, than to right themselves by abolishing the forms to which they are accustomed. But when a long train of abuses and usurpations, pursuing invariably the same Object evinces a design to reduce them under absolute Despotism, it is their right, it is their duty, to throw off such Government, and to provide new Guards for their future security. ”
    Currently regarding and this is being generous the drug war alone we have the right to hold our current government guilty of treason against the citizens of the United States and for bearing false witness and false imprisonment based on perjury. This would amount to total number of counts being the total number of American citizenship at this time.

    I truly believe you have a valid point and the information presented is indeed true. However, you and I both know that the majority of Americans today are not aware that the government has been forcefully brainwashed and poisoned (hello people!!! Fluoride is Not and NEVER has been good for us!!! Look it up for yourself, this is what Germany did to the Jews during their imprisonment, gave them “fluoride treatments” to test the effects of the poison on the brain) But I digress…We have been wronged, the very foundation of our country has been violated over and over again by the “people in power” when the truth of the matter is that the people of power are suppose to be the citizens, me, you, the average joe…….The country was suppose to be a democracy not a dictatorship (the people with money being the dictators)….Yes America is a Dictatorship, when are we going to finally turn this country into what we have been “claiming ” it is for over 400 years, a country made by the people, operated by the people and for the good of the people. And I honestly do not see this happening anytime soon, not until the corruption is out of the government (at least 93% is currently corrupt)…The officials should ALL be charged with treason but we are too afraid as a nation to stand up and eject them….sad, so sad, this is why I personally will retire overseas…..

  37. Dave 2 years ago

    While I don’t agree necessarily with them being able to patent a plant, I have two points to make. 1) I think they are getting a patent on the treatment process itself and not the plant, and 2) If they succeed then it shows the cannabis does have medical value and it cannot be a Schedule I drug any longer, which will help ease the process for legalization.

    Kind of a broad statement don’t you think? There are plenty of types of cancer that aren’t very reachable at all to inject oil into.

  42. nature 2 years ago

    The US allows for use patents ie Herb x can be used for disease Y. Then no one else other than the patent holder can claim that! There are both positives and negatives to this. Positive is that the patent holder will then pay to prove this. So it will come out of the realm of snake oil and into the realm of medicine. Downside is that one corportation then owns the patent and others cannot claim the same!

  43. Starsoul 2 years ago

    There is no ‘injection’ of oil involved. It is ingested ie. swallowed orally to then work its magic inside the body and deal with any and all types of cancers.

    Wow… Just wow… completely unethical, harrassing & illicit treasonous corporately-influenced governments trying to eat a cake & have it too – a cake that WAS NEVER THEIR’s IN THE 1st PLACE.

    Crime of the Century? That be Cannabis prohibition now for 80-100 years too long already.

    Sativex does work but not as well as naturally produced cannabis oil with all the cannabioids not just THC/CBd. Sativex is also ridiculously expensive

  54. Jean 1 year ago

    First, you can’t patent a plant…cannabis belongs to humanity. sECOND, CANNABIS WAS IN THE PHARMACOPOEIA LONG BEFORE research ‘re-discovered’ the curative nature of cannabis, which was used as medicine for many conditions and diseases before prohibition in the 1930s. Third, the cancer-curing properties of cannabis have been known since the 1970s, but suppressed by the U.S. government. In the early 2000s, canadian rick simpson developed a simple cannabis extraction method he makes available to humanity free, and he personally cured thousands of people of many illnesses…including terminal cancers and gliomas, for free. For his efforts he was vilified by the government of canada and has since lived in exile for spreading the knowledge of the cancer-curing properties of cannabis globally. he was personally responsible for saving the lives of many people. GW, or any pharmaceutical corporation, are not the heroes in the cancer-curing cannabis story and have no right to patent any of the healing properties of the natural healing plant. Should they by some miracle create a plant outside the bounds of nature that has healing properties then sure, patent it. but not cannabis, the queen of healing herbs, that has belonged to humanity, and used by humanity, for eons. if we sanction this patent then nothing will prevent other pharmaceutical companies from patenting cannabis and other healing plants. bayer has long been trying to patent nigella sativa and corner the global market on black seed oil…a legendary ancient remedy said to cure everything but death.
