IBM United Kingdom Limited v LzLabs GmbH & Ors

IBM United Kingdom Limited v LzLabs GmbH & Ors

Winsopia breached the ICA by reverse engineering, disassembly, decompilation, and transferring IBM proprietary software to LzLabs for SDM development, in breach of express contractual restrictions. These acts did not fall within statutory exceptions under the Software Directive/CDPA. LzLabs and Mr Moores unlawfully procured and conspired in these breaches. The audit request and termination by IBM were valid. Claims are not time-barred due to deliberate concealment of the Winsopia-LzLabs connection. Directors Cresswell and Rockmann are not personally liable due to the Said v Butt defence. Claims against LzLabs UK fail for lack of causative participation.
