According to 18.37.3 and 4, microorganisms cannot be excluded from patentability. I assume this is to allow patenting of things like probiotics. However, all humans rely their skin, mouth, and gut floras to be healthy. If the bacteria and yeast in that flora can't be excluded from patentability, are they considered not a part of the human animal? I understand that probiotics should be protected, but I wonder if someone could take advantage of this and claim patent on any naturally occurring microorganism by just isolating it and showing that it has some use. Something else not specified in this section are viruses. Viruses are not strictly microorganisms, and no mention is made of them, but yet they can be manufactured and used for treatments- recently even for cancer: http://www.mayo.edu/research/departments-divisions/departmen... http://www.theguardian.com/society/2015/nov/02/fda-approval-... If viruses could be excluded from patentability since they aren't mentioned, then any research or manufacturing done would not be patentable, and therefore some companies may hesitate to invest too heavily in research. |
Still, seems a little odd / slippery slope-y to me. On the one hand, I understand and, to some extent, agree with the need to protect / profit off what you've developed. On the otherhand, USPTO is pretty bad at biological patent screening and I can see a huge landrush to patent bacteria for no good reason.
(Full disclosure, I am in the process of patenting a modified natural product made by a bacteria)
