Pfizer participated in the campaign to make the WTO impose patents worldwide, including patents on drugs. Now it cites that plutocatist coup as a "principle" that it would be unthinkable to reject.

My view is that we should eliminate patents entirely, and most especially eliminate them from medicine, agriculture and software.

The article has a confusion because it uses the term "intellectual property". That is a catch-all term for several unrelated laws (patent law being one), so sometimes the article is talking about patents and sometimes it is implicitly talking about other things as well.
