Markzware has filed an LA lawsuit against Enfocus Software on claims the latter firm breaks patents it holds on pre-flighting software.

Markzware filed its lawsuit in the Federal Court in LA against Enfocus Software; Artwork Systems Group and Artwork Systems.

The company alleges that products manufactured and sold by the defendants infringe upon its US Patent No. 5,963,641 for a 'Device and method for examining, verifying, correcting and approving electronic documents prior to printing, transmission or recording.'

Markzware preflight products include FlightCheck Professional, FlightCheck Designer, FlightCheck Studio, FlightCheck Workflow and FlightCheck Online.

The complaint seeks monetary and injunctive relief from all three defendants.

Patrick Marchese, president of Markzware commented, "The preflighting described in the '641 patent and owned by Markzware, has been used without our consent. Accordingly, we plan to protect and defend our patent which is fundamental to our flagship product line, FlightCheck."
