Patents
PatentsHere is the response of Ivanhoe Investor Relations to my email query:
Since 1998, core patents (US5792340 & US5961786) related to the HTL
technology were successfully obtained. Other patent applications related
to heavy oil upgrading, viscosity reduction, and total acid number (TAN)
reduction are currently pending (PCTWO00/61705 & PCTWO02/24835).
Ivanhoe Energy believes that it has broad patent coverage from the
original Ensyn's RTP(tm) patents that expire in the USA in 2015. These
patents presently provide coverage in key markets, including Canada and
USA. In addition, Ivanhoe Energy has a number of patents and patents
pending applications for petroleum "HTL" applications of RTP(tm) in the
USA and Canada and other countries as well. Once granted, they will
provide patent protection beyond 2022.
