Michael if that is true how does it relate to the NIMH patent in Japan that was issued in 1997 but is only good until 2003. It seems it starts from the application date, so unless ECD waited 20 years to apply for the patent that Retiarius was referring to, the most important fundamental patent if issued would be expired. Anyway I'm sure that we will know more about it this week. Dates of particular interest in the historic patent registration process: Application Date: April 22, 1983 Publication Date: December 18, 1992 Registration Date: August 15, 1997 Duration (20 years from application): Until April 22, 2003 Registration Number in Japan: 2131429 Virtually all of Japan's NiMH battery manufacturers have patent agreements with Ovonic Battery covering consumer NiMH batteries. With the patent recognition in Japan, these manufacturers must pay substantial amounts based on sales for all NiMH batteries produced in Japan in the past, from the date of publication, until April 22, 2003.
