The summary says Langdon has patented a 'new strain' he has been growing for the past 15 years. The strains aren't new in the plant breeding sense, they are existing natural strains of the seaweed grown in isolation, here is the patent. I fail to see what is patentable here; just a description of various naturally occurring strains of dulse and their comparative growth rates. So, if I were to collect the seaweed from the Pacific coast and 'isolate' the same strains, I'd be infringing a patent? What a joke.
