A Lovely Couple of MJ Patents for Valentines Day, and More

“Cannabis Plant Mr. Grass Weedly” was published on January 3, 2019 as US2019/0000029.  We here at MJPW are nearly giddy to announce that he won’t be spending this Valentines Day alone…because…you guessed it…“Cannabis Plant Named Mrs. Grass Weedly” was published on February 7 as US2019/0037792 and appears on MJPW as part of our Valentines Week update. Both patents relate to hybrid cannabis cultivars and products derived from them. We wish them a happy time together at the Patent Office.

Another notable publication this week is US2019/0037909, “Cannabis-Based Moist Snuff.” It covers a wide range of Cannabis-based snuff products looking to unseat chewing tobacco. It is certainly worth watching as it moves forward through the patent-examination process.

Other interesting additions this week include a system for detecting cannabis and opiate use through breath, treatments for neurodegenerative disease, cocaine use, and HPV, and methods for purifying cannabis extracts.  Whether you love innovation, or love Cannabis itself, or just love a love story, you’ve gotta love this week’s update.

Synthetic Cannabinoid…Mother’s Milk…Xylooligos


The only MJ Patent to issue on Tuesday January 22, 2019 was US10183930B2, claiming crystalline forms of cannabinoid receptor modulators. In plain English, super-pure forms of molecules that bind to CB-2 (the same receptor that CBD binds to).

The patent lists treatment of disorders such as osteoarthritis; osteoporosis; autoimmune disorders; allergic reactions; atherosclerosis; anaphylaxis, graft rejection, gout, lupus, inflammatory bowel disease, autoimmune hepatitis, and type 1 diabetes mellitus; age-related macular degeneration; leukemia; lymphoma; prostate cancer; Alzheimer’s disease; stroke-induced damage; dementia; amyotrophic lateral sclerosis; and Parkinson’s disease.

New applications published on Thursday January 17, 2019 included a dairy product made of human mother’s milk as its base product, “which has been tested for absence of undesirable chemicals, including prescription medication, illicit drugs, nicotine, and alcohol. With the prescription medication including lithium, chemo therapy agents, Ergotamine, and Bromocriptine, and the illicit drugs including any mind altering substances including marijuana, cocaine, heroin, and Lysergic acid diethylamide (LSD).” US20190014790A1

Another new application ferments carbohydrates found in Cannabis plants, producing flavor factors that include phenolics and everyone’s favorite spelling-bee word: xylooligosaccharides, and then optionally removes the alcohol made during the fermentation process. WO2019010576A1

A Tooth Camera to Watch Whether You’re Lighting Up or Brushing

This week’s most jaw-dropping patent has got to be US10178946B2, which issued on January 15. It claims an “oral monitoring system … adhered to a tooth for capturing images over a period of time” and yes, those images are intended by the inventor to include everything from good oral hygiene to marijuana use.

Other Cannabis-related patents this week include US10179109B2, a pharmaceutical composition treat headache and photophobia; and US10179683B2, for formulations containing cannabinoids for administration via a pump action spray. There were also 11 new US patent applications published on Thursday, January 10 and 6 new PCT applications published the same day.

Peruse…But also Comment on the Public Domain

The MJ Patents that issued on Tuesday, January 8 included a CDB toothpaste, an enhanced smokable plant material coated with cannabinoids extracted from spent hash resin, and a pain-relieving CBD mousse for dogs and other non-human mammals. MJ Patent Applications that were published on Thursday, January 3 included several biotech, medical, and agricultural-oriented inventions.

We invite the users of MJPW to not only peruse the over 10,000 US, Canadian, and International patent documents in the database, but also to comment on anything that appears to be an attempt to take subject matter out of the public domain. See “Patenting and the Public Domain” at PlantLaw.com.

A Christmas MJ Patent, and the First Patents of 2019

It is fitting that the only patent in this category to issue on the final Tuesday of 2018 (Christmas Day) was Design Patent USD0836484S, for a holiday wreath made of artificial marijuana leaves. Perfect timing, USPTO and inventor Michael Chadwell!

Then a week later, New Year’s Day 2019, four patents issued, covering “a method for producing powderized cannabis oil” (US10165790B2); a method for “reducing oxidative stress in liver tissue” using CBD (US10166202B2); a “flow regulating inhaler device” (US10166349B2); and a “cannabis plant stimulation lighting system” (US10165735B1).

These are examples of the diversity of the industry as it ends 2018 and moves into 2019.
