Some of the patents may be getting old but their term is effectively extended by modifications/derivatives.

Thanks for recapping the patent info; I believe EU patents have a duration of 20 years from the filing date:

We also had favorable ruling in EU when our patents were challenged:

Like Iggy was implying, many of our patents have been renewed/modified as the science has evolved:
