Intellectual Property

Nufern Intellectual Property

Nufern respects the intellectual property of others. We place considerable effort on our own creativity and in owning a relevant and strong patent portfolio, so that we can provide our customers with an advantageous and defensible IP covered product. Our staff is encouraged to create patents, and we have inventors at nearly every level in our organization. Our focus is on generating IP related to optical fibers, fiber lasers, and fiber amplifiers. Where necessary Nufern also licenses IP from others so that we can practice optimized solutions not created here.

All Nufern patents are available for license.  Nufern owns or licenses the following patents:
