Solarium and Philips are facing a lawsuit that claims they stole intellectual property and were not authorized to sell it.
Solarium filed the suit Wednesday in U.S. District Court in New York.
It claims that Philips infringed on patents that it has used to manufacture products that have become essential to people living outdoors.
In a filing that’s nearly 30 pages long, Solarium says Philips has used the patents for products that include solar panels, solar powered snow machines, and solar water filtration systems.
Solarium alleges that Philips “failed to make reasonable efforts to protect its intellectual property rights in the face of a widespread, coordinated, and aggressive marketing campaign that targeted and defamed Solarium, its product lines, and its suppliers.”
Solarium has filed an antitrust lawsuit against Philips and the makers of the Philips Facial Solarium.
Philips did not immediately respond to a request for comment.
In an interview with Reuters last year, Philips Chief Executive Tom van Essen said that he thought it was safe to say that the facial solar products were “more or less a technology in its infancy.”
Solarium has said that the company has sold 1.7 million facial solar devices in the United States.
Solaris patents were first filed in 2001.
The company is a division of Philips, which is a global leader in home, office and commercial solar energy technology.
The company’s products include solar water filters and solar solar snow machines.
