GTC Biotherapeutics (fka GTCB)

[used to make chicken]

I haven't read the milk patents in some time, but there are a couple of things to consider.

1) Do the GTCB patents cover production in milk using all available promoters, or are they still limited?

2) If a party such as Velander can demonstrate knowledge and use of such production means before the patent was applied for, they have freedom to operate in most cases.

3) Up to 300 liters a year from a giant hungry sow is not a whole lot of milk.
