I don't think you could class this as a name change, because ESYR is a subsidiary (owned) by GERS (unless I have been misinformed)and which concentrates on the technical innovations of the processing & Patent development. I may be overstating the importance of ESYR, but think that is basically the status. Don't take my word, check it out. Sometimes these relationships get complex! All this JMO, but I do read a lot! Heh! Wouldn't it be a hoot if ESYR got all the Patent Infringement settlements!~
Just say'n!
