Patents by Inventor Bohdan Grzegorz Cieslinski

Bohdan Grzegorz Cieslinski has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 9453950
    Abstract: The present invention provides a method for manufacturing a photochromic article having a photochromic compound containing layer. The method includes the step of coating a casting face of at least one mold section with a photochromic host layer. The photochromic host layer is treated to minimize damage during subsequent steps, and a mold is then assembled so that it includes the mold section having the photochromic host layer. The mold is then filled with a photochromic article monomer composition and the monomer composition is subsequently cured to form a photochromic article substrate adhered to the photochromic host layer. The photochromic compound is introduced into the photochromic host layer.
