Publication of PCT Patent Application on Elpipes

The PCT patent application on elpipes was published yesterday by WIPO, on March 17, 2011, Saint Patrick's Day. That patent application covers several independent ideas, including both new insulation concepts, new types of joints; the concept of an elpipe as a wheeled, powered vehicle (an elpipe train, in effect). I fully expect this patent to lead to numerous divisional applications when it gets to national phase patent prosecution.
