Several new green patent complaints have
been filed recently in the areas of biofuels, smart grid, LEDs, solar
manufacturing materials, and waste water treatment. Here's a run down:
Butamax Advanced Biofuels v. Gevo
The complaint (Butamax-Gevo_DJComplaint) was filed August 9, 2011 in the District of Delaware.
Butamax, a joint venture between BP and DuPont, accuses Gevo of infringing U.S. Patent No. 7,993,889,
entitled "Fermentive production of four carbon alcohols," and directed
to methods for producing isobutanol by fermentive growth of a
recombinant yeast microorganism.
This is the second patent infringement suit filed by Butamax against Gevo. I covered the first complaint here.

The complaint (Nxegen-Complaint) was filed July 29, 2011 in the District of Connecticut.
Nxegen asserts two related patents against Sensus, U.S. Patents Nos. 6,633,823 and 7,135,956,
entitled "System and method for monitoring and controlling energy use"
and directed to systems and methods for monitoring and controlling power
use among a number of facilities to reduce a real-time aggregate power
load across the facilities.
The accused products include the FlexNet Advanced Metering re Infrastructure (AMI) solution.

entitled "Wireless network gateway and method for providing same," and
directed to certain wireless network systems having a server providing a
gateway between two networks.
The other named defendants are Schlage Lock Company, Trane and Schneider Electric
Intus is a patent licensing company and appears to b e related to Sipco, which has been a patent enforcement spree, including suits against utilities, smart meter companies, and EV charging companies.
ICH Intellectual Capital Holdings v. Badger Meter et al.
The complaint, filed September 8, 2011 in the Eastern District of Texas, accuses a host of smart meter players of infringing U.S. Patent No. 7,248,181,

meter reading system adapted to facilitate readings by an operator
walking or driving close to the system at a low power level and at a
