I am certain most of you are well aware of the US Federal Patent on CBD. If not:

Cannabinoids as antioxidants and neuroprotectants 
US 6630507 B1
Cannabinoids have been found to have antioxidant properties, unrelated to NMDA receptor antagonism. This new found property makes cannabinoids useful in the treatment and prophylaxis of wide variety of oxidation associated diseases, such as ischemic, age-related, inflammatory and autoimmune diseases. The cannabinoids are found to have particular application as neuroprotectants, for example in limiting neurological damage following ischemic insults, such as stroke and trauma, or in the treatment of neurodegenerative diseases, such as Alzheimer’s disease, Parkinson’s disease and HIV dementia. Nonpsychoactive cannabinoids, such as cannabidoil, are particularly advantageous to use because they avoid toxicity that is encountered with psychoactive cannabinoids at high doses useful in the method of the present invention. A particular disclosed class of cannabinoids useful as neuroprotective antioxidants is formula (I) wherein the R group is independently selected from the group consisting of H, CH3, and COCH3.
Well, there are actually a number of US Federal patents on cannabis. Over time, I will try post many of them with some thoughts on my end. So, below is another Federal Patent from 2009. This patent is for “Anti-tumoural” effects of Cannabis. Here is the brief intro to the patent:
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)
The rest can be found at: https://www.google.com.au/patents/US8632825.
So, we are talking about various ratios of CBD:THC for treatment of Glioblastoma Brain Tumors. As I have said in the past, nobody patents a medication if there is no evidence of that it might actually work. I take these patents as support of the work we are all doing.
Does CBD:THC work for Glioblastomas? Here is more evidence that it does.
