Employer was owner of works created during employment
In this case, Mr Penhallurick claimed ownership of copyright in eight works, all of them relating to a technique he called "Virtual Forensic Computing", or "VFC". He alleged infringement of his copyrights by his former employer ("MD5").
MD5 asserted that it owned the copyrights and counterclaimed for a declaration to that effect, also claiming that Mr Penhallurick was in breach of his contract of employment and had infringed MD5's copyrights.
