The licensing fees we're talking about farmers getting sued over are for the Roundup-ready crops, not the herbicide. The point of the Roundup-ready system is that it allows you to plant crops that aren't killed by Roundup. As someone else noted, you can buy Roundup itself at Wal-mart.
I think even a cursory read of the thread would have indicated to a good-faith commenter that I know the basics of the difference between Roundup and the Roundup-ready GMO product.
You're right about the seed currently being a bigger source of revenue and profit than RoundUp, because it's currently protected by patents whereas the herbicide patent expired in 2000, and now Monsanto is being undersold on generic glyphosate (without its special additives) by Chinese chemical producers who have been incentivized and subsidized by their government.
However, RoundUp seed patents begin expiring with soybeans first in 2014, and it looks like canola will follow a year or three later.
RoundUp (the herbicide) apparently accounts for 10% of Monsanto's revenue, but the corresponding seed will soon account for zero.
