Software under licensing
We have seen several of the major IT suppliers seeking to make multi million pound claims against large organisations who have customers, suppliers and/or employees using systems which connect directly and/or indirectly (and in some instances to a very limited degree) into the IT suppliers' software. Software under licensing disputes (and related claims concerning alleged indirect use and/or indirect access to systems), can therefore arise in all businesses, across all sectors – particularly those organisations with large IT systems.
We have resolved many such disputes and continue to assist clients in substantially reducing/eliminating these claims. We acted on the leading case in this area (SAP UK Limited v Diageo Great Britain Limited [2017] EWHC 189 (TCC)).
