Afinia updates the status of the litigation brought by Stratasys, Inc., noting that it has commenced Inter Partes Review of the asserted patents at the U.S. Patent Office. The Inter Partes Review addresses the validity of U.S. Patent Nos. 5,855,058; 6,004,124; and 8,349,239 (the other asserted patent was withdrawn by Stratasys). Afinia maintains that the asserted patents are both invalid and not infringed.
