Cleantech patents used in anger by Justin Blows

There is plenty of legal action around Cleantech patents, but two incidents recently attracted my attention.

The first is TurboSonic v EnviroCare, reported here. These companies were tussling over alleged infringement of US and Canadian patents for the scrubbing of exhaust gases of acidifier. The companies settled and the patent managed to get a licence deal. That sounds like a great outcome for the patentee.

The second is reported here, and involves the enzyme giants Danisco and Novozyme. The technology relates to alpha amylase for ethanol – a biofuel – production. There appears to be a lot at stack – Danisco estimates the global market for
second-generation biofuel will grow to $75 billion by 2020.

These cases show, once again, how important patents are for commercial advantage in competitive areas such as Cleantech.
