GTC Biotherapeutics (fka GTCB)

[DewDiligence]

>Since GTCB now has the broad US patent for the production of any therapeutic protein in the milk of any transgenic animal (through 2021), will potential competitors like Pharming and Avigenics first have to obtain a license from GTCB prior to commercializing any of their transgenic products?<

Pharming, yes. Avigenics, no—unless the scientists at Avigenics have figured out a way to make chickens lactate. I suspect this hasn’t happened because it would have been a pretty big news story, no?

>Do you know if GTCB has a similar patent in Europe, or one pending?<

They do, but it expires in the mid-20-teens rather than 2021.
