Printing Industries of America Seeks to Invalidate Workflow Patents
Printing Industries of America filed petitions last week with the United States Patent and Trademark Office (USPTO) in an effort to nullify two digital workflow patents that have been the basis for lawsuits against printing companies. The petitions seek an inter partes review by the USPTO of the patents' validity.
The patent owner has aggressively sought licensing fees from dozens of printing companies and has sued many of them for infringement. The patents broadly address methods for receiving customer files, using a computer network to perform various prepress functions, and creating a plate-ready PDF file.
