ORIGINAL: WinsomeDefiance I worked at Exxon for fourteen years, in various departments. I know that there were many patents that were purchased by Exxon (now ExxonMobil). At the time, it was assumed they were purchased to shelve any competition, which they were, but I wonder now how many of the patents for the world's future energy needs are already owned by ExxonMobil and other such companies. The most important one that definitely works is on batteries. The nickel metal hydride, NiMH, technology used in the successful EV-1 and Rav-4EV is owned by Chevron and they're making sure no pure electric vehicles gets done with it until the patent expires in 2015.
