The Acuity Brands' products are using exclusive right to use of the far-ultraviolet UV-C 222 nm light source by a patent of the Columbia University,
and this Japanese company has obtained an exclusive license worldwide from the Columbia University.
In the U.S. market, those products are sold by U.S. companies that are collaborating through the U.S. subsidiary of this Japanese company.

these approaches are beneficial to the Biden-Harris administration's healthcare policy, I think and wrote in above.
