MORRIS TOWNSHIP, N.J., Sept. 30, 2009 – Honeywell (NYSE: HON) announced today that it has received an Intention to Grant from the European Patent Office for a patent application that covers the use of its new low-global-warming refrigerant, HFO-1234yf, in automobile air conditioning.

This notice from the European Patent Office is the last step in the European patenting process, and Honeywell expects the patent to issue by the end of the year.

This European Intention to Grant is one in a series of notices of allowance and patent grants that Honeywell has received worldwide related to its low-global-warming solution for automotive air conditioning applications.

Honeywell has invested considerable resources to identify next-generation solutions for our customers and has filed more than 70 unique patent families worldwide to protect this investment. The portfolio spans the United States, Europe and Japan and includes two issued U.S. Patents related to the use of HFO-1234yf in air-conditioning systems.

"We're pleased that the European Patent Office has recognized Honeywell's right to patent the use of HFO-1234yf as an environmentally preferable refrigerant for automotive air conditioning," said David Diggs, global business director for Honeywell Fluorine Products. "Honeywell has made significant investments to develop our intellectual property, and we work diligently to protect our patents from infringement worldwide."

Honeywell expects the European Patent Office and the U.S. Patent Office to issue additional HFO-1234yf patents to the company in the coming months.

Honeywell worked jointly with DuPont to commercialize HFO-1234yf for use in automotive air conditioning in response to the European Union's Mobile Air Conditioning Directive, which requires that all new vehicle platforms produced starting in 2011 use a refrigerant with a global warming potential (GWP) below 150. All new vehicles will be required to use a low-GWP refrigerant by 2017. Current mobile air conditioning systems use HFC-134a, a refrigerant with a GWP of 1,300. HFO-1234yf has a GWP of only 4. This new refrigerant is part of a larger platform of low-GWP materials that Honeywell is developing, including refrigerants and blowing agents.

Honeywell's significant investment in research and development has led to numerous patents relating to the other refrigerants including R-410A, R-404A, R-408A, R-507, R-236fa and 245fa.
