They'll settle and allow them to make the product for a cut:
"To many industry watchers, the lawsuit regarding the Vizia line was no surprise. Lutron, whose RadioRA arguably was the first two-way RF lighting control product to hit the market back in the 1990s, cites four key patents that date back to 1993.
The company sued Control4 last year for patent infringement (that suit is pending) over the manufacturerâ€™s Zigbee-based lighting control products. Control4 says more than 100 thousand units have been sold to custom installers.
Prior to that, Lutron settled a case with Vantage Controls (now Vantage/Legrand) over the same patents. That case, involving Vantageâ€™s RadioLink RF-enabled lighting controls, was settled before it ever went to court, and Vantage continues to make the products in question."
