Law question

John is the managing directors of Pearson Ltd, a medium size company which sells custom made Italian light fixtures. For the past 12 years, John has exclusively imported component parts from the Italian based company Lumitalia spA, who create innovative light fittings in a number of different designs and shapes.

During the course of an annual visit to the Lumitalia spAoffices in Milan, John renegotiates his contract with Emilio Schwarza, the managing director of LumiatliaspA, and they agree Pearson Ltd will buy the design blueprints for two of Lumitalias more successful ranges, so Pearson Ltd can manufacture the ranges themselves back in the UK.

John flies back to the UK, and arranges the transfer of funds to Lumitalia, but three months has subsequently passed and the design blueprints have still not been provided.

Advise John on any possible approaches he may want to consider in order to resolve this dispute.
