Patent Protection

The LYCRA® brand pioneered the development of dual core technology and transformed denim in the process. The popularity of denim featuring the performance benefits of LYCRA® dualFX® technology has led some companies to try to sell infringing denim fabric. IP protection matters to us.

To vigorously protect our intellectual property and the integrity of our dual core patents around the world, we regularly purchase garments made with dual core fabrics at retail and test them for patent compliance. To date, we have identified a number of violators and have converted millions of yards of fabric to genuine LYCRA® dualFX® technology.
