Reverse engineering through the systematic use of traces, dumps, slip traps, packet sniffing and other debugging tools techniques – summary of the dispute

523.

IBM’s case is that Winsopia made systematic and extensive use of diagnostic and debugging tools for the purpose of investigating and analysing components of IBM mainframe software and their interactions, amounting to reverse engineering; further, that Winsopia provided the results of such reverse engineering to LzLabs for use in developing the SDM in breach of the ICA.

524.

The defendants’ case is that Winsopia used such tools to understand the behaviour of customer applications on the mainframe and to observe, study and test interface information relating to the interfaces of the customer applications with the IBM runtime environments, pursuant to its rights under Article 5(3) of the Software Directive.
