EBykr has a great historical post of Mavic.

Mavic had developed what was called a Duralumin dished rim using eyelets to distribute the stress of spokes on both the upper and lower walls of the rim. It was a new concept that was both lighter and stronger than typical steel rims, but a mere two hours before Mavic could patent the design, an Italian man named Mario Longhi beat them to it. He’d developed an identical design and was quicker to the patent office than Mavic - a fluke occurrence for sure, but one that could have ultimately jeopardized Mavic’s future.
