The Canadian Intellectual Property Office has just granted Aquaporin A/S the Canadian patent No 2621807 titled “BIOMIMETIC WATER MEMBRANE COMPRISING AQUAPORINS USED IN THE PRODUCTION OF SALINITY POWER” adding another important step towards Aquaporin’s future market entry on the North American continent.

The Canadian patent adds to the list of issued patents covering the use of the Aquaporin Inside™ membrane technology in salinity power applications. In addition, patents have been issued in the USA, Europe and China.

Salinity power is a CO2 neutral and sustainable power source originating from osmotic gradients arising where fresh or brackish water flows into saltwater. The Aquaporin Inside™ membrane technology offers a solution to the existing challenges of securing sufficiently high water permeability, low reverse salt flux and low structure parameter and at the same time keeping concentration polarizations and fouling issues at a minimum, cf. Alsvik & Hägg, Pressure Retarded Osmosis and Forward Osmosis Membranes: Materials and Methods, Polymers 2013, 5, 303-327.

For more information on the issued patents and the technology or if you wish to discuss the possibility of obtaining a licensing agreement to the invention, please contact Head of IP Department Marianne Spanget Larsen at or phone +45 2710 2077.
