EFI Reports Invalidation of Claims in Durst’s White Ink Patent

Electronics for Imaging (EFI) of Fremont, California announced that the Federal Patent Court of Germany (BPatG) has invalidated substantial parts of a patent related to white ink printing. German patent No. 10 2005 006 092 is held by assignee Durst Phototechnik Digital Technology GmbH (Durst). EFI says this is the patent that Durst claimed was infringed in a case against it.

EFI noted it filed an action in BPatG to ask for invalidating certain claims of the German patent which Durst alleged EFI had infringed for years. As BPatG has now agreed with EFI the company believes that if Durst fails to appeal the decision, the multi-year legal battle will come to an end.

Bryan Ko, General Counsel at EFI, commented, “We at EFI believe that competition should be customer-focused, not litigation-focused. It should be based on genuine innovations, not on questionable patent claims. And it should take place in the marketplace, not in the courtroom. We will always defend ourselves vigorously when necessary, but we will continue to focus first on ideas and technology to help our customers succeed.”
