Reproduction Research
Russian metallurgist Pavel Petrovich Anosov (see Bulat steel), Dr. Oleg Sherby and Dr. Jeff Wadsworth and Lawrence Livermore National Laboratory have all done research, attempting to create steels with similar characteristics to Wootz. However none have had any success so far and the original techniques used to produce wootz steel in India have been lost for centuries.
There are no patents or trademarks for wootz steel (US Patent and Trademark Office).
