Oil Companies Patent Trolling Biofuel Production

Whatsmynickname writes "Thought oil companies were done patent trolling to try to shut down any efforts to wean us off of crude oil (e.g. Chevron and NiMH batteries)? Think again. BP and DuPont (Butamax) have taken an advanced biofuel company to court over infringement of newly awarded patents for developing biobutanol. When an oil company advertises it is looking for alternative fuels, it's not necessarily because they want to be socially responsible..."

Butanol isn't a replacement for Ethanol, it's a replacement for gasoline!

Butanol may be used as a fuel in an internal combustion engine. Because its longer hydrocarbon chain causes it to be fairly non-polar, it is more similar to gasoline than it is to ethanol. Butanol has been demonstrated to work in vehicles designed for use with gasoline without modification.[1] It can be produced from biomass (as "biobutanol")[2] as well as fossil fuels (as "petrobutanol"); but biobutanol and petrobutanol have the same chemical properties.

Historically Butanol and acetone has been produced by fermentation of starches and sugars by Clostridium acetobutylicum what the Butamax patent claims is a method of spicing the genes from C. acetobutylicum that make butanol into other organisms. The patent is very specific about which gene sequences do what and are inserted into the host cell, rather than the typical overly broad patent from typical patent trolls.
