CBD Extraction Showdown: Canopy Growth Sues GW Pharma

In a patent showdown between two high-profile players in the emerging cannabis industry, Canadian corporation Canopy Growth has sued UK-based specialty pharmaceutical company GW Pharmaceuticals over a utility patent directed to CBD extraction technology.[1] In its complaint, filed in the Waco division of the Western District of Texas, Canopy alleges that GW practices its CBD extraction invention to make GW’s landmark pharmaceutical for treating certain forms of epilepsy, Epidiolex. As we have previously reported, Epidiolex is the first FDA-approved cannabis-derived pharmaceutical for treating certain forms of epilepsy and has become a working model for how to bring cannabis-derived therapies to market in the United States.[2] [3]

The suit is notable both for its choice of venue and that it marks the beginning of patent-related confrontations between powerful players in this dynamic and emerging industry. The venue is notable as part of a broader trend in patent enforcement to bring suit before Judge Alan Albright, whose default rules keep patent disputes moving quickly and on a predictable timeline towards claim construction and trial. This speed and predictability has a unique interplay with patent challenges before the Patent Trial and Appeal Board (PTAB).[4] As for the implications of this case for the cannabis industry, stay tuned for insights from us as this litigation unfolds!
