SIGA wins hygrobrid technology patent challenge. The technology is found in products like Majrex

Ruswil, Switzerland - July 11, 2018 - The European Patent Office ruled in favor of SIGA in a major patent and intellectual property case, EP2759403. The court found that SIGA’s Hygrobrid® technology used in industry innovations such as the SIGA Majrex® is completely new and claims against the originality have been rejected.

SIGA Majrex is a smart directional vapor retarder that limits moisture transportation into the wall cavity and at the same time maximized inward drying. The result is a dry and mold free assembly over the life time of a building.

“SIGA believes in the strengths of its development competences and ability to innovate in the industry,” said Stefan Schaab, CPO, SIGA Cover AG. “This settlement represents another successful milestone in defending the intellectual property that enables us to provide superior products like the Majrex to our customers.”

The Institute of Building Climatology in Dresden, Germany, carried out testing on flat roof assemblies under construction-relevant climate conditions. They proved that the Hydrobrid technology works and that SIGA Majrex has a highly directional permeability.
