SAP v Diageo – the UK’s first software over-deployment case: takeaways for business

The interconnected world of the 4th industrial revolution is driven by software. As software functionality continues to expand through developments in algorithms, AI, APIs, business process automation and smart contracts, software systems increasingly interact more widely and with more and more other systems. It is not surprising therefore that issues around software over-deployment – where the provider says the customer is using software beyond what is contractually permitted and owes more money – are on the rise. February 2017 saw the first UK High Court judgment in this area with the judge applying normal contract interpretation rules and finding in favour of the provider. The key takeaways from the case for customers are then to make sure the wording in the software licence grant clause maps precisely to intended software use and then to operate a structured process to review that mapping throughout the licence lifecycle. For providers, the watchwords are ‘trust and verify’ through workable audit mechanisms.

Contractual language to define the scope of permitted software use and to determine charging basis may have been agreed years ago. That language now finds itself applied to new technologies and interfaces in a way that was unanticipated when the agreement was signed. Increasingly, providers are scrutinising customers’ use of their software to ensure that use is in accordance with the terms of the licence and that the charges paid by the customers reflect actual usage of the software.

This trend for heightened scrutiny of customer compliance with licence terms is the background to the 16 February 2017 judgment of Mrs Justice O’Farrell in a case between SAP UK Limited (“SAP”) v. Diageo Great Britain Ltd (“Diageo”).

Briefly, the facts are as follows:

  • From May 2004, Diageo was licensed to use various SAP products, including mySAP ERP (“SAP ERP”) and SAP Process Integration (“SAP PI”). SAP ERP provides a suite of enterprise resource planning functions for managing operations, finance and HR. SAP PI facilitates communication between different SAP systems or between a SAP system and a non-SAP system. The licence to access and use the software – directly or indirectly – was on a Named User basis. Fees for SAP ERP were calculated by reference to various fees for categories of Named User. Fees for SAP PI were calculated on the volume of messages processed by SAP PI. Diageo paid SAP between £50 million and £61 million by way of licence and maintenance fees for the period up to November 2015.
  • In 2011/2012, Diageo used a system that enabled customers to place and review orders and manage their accounts directly with Diageo rather than (as previously) through a call centre (”Connect”) and a platform provided by to develop an iPad app for the management of customer visits and calls (“Gen2”). Connect and Gen2 interacted with SAP ERP via SAP PI. Messages were passed back and forth between Connect or Gen2 and SAP ERP a few times a day when the SAP ERP was polled for information by Connect or Gen2.
  • SAP claimed that Connect and Gen 2 “used” or “accessed” the SAP systems “directly” or “indirectly” and that Diageo owed additional licensing and maintenance fees totalling in excess of £54million. Diageo contended that SAP PI was a “gatekeeper” for the other SAP applications and that no extra fees were due.

In a trial on liability – but not the amount of damages – the English High Court ruled in favour of SAP:

  • On the plain and obvious meaning of the words in the licence only ‘Named Users’ (as defined) were authorised to access and use SAP ERP, and the extent of their permitted access and use then depended on their user category set out in a schedule to the agreement. Although the terms “access” and “use” were not defined in the licence, “the plain and obvious meaning of “use” in the context of the Agreement is application or manipulation of the mySAP ERP software. The plain and obvious meaning of “access” in the context of the Agreement is acquiring visibility of, or connection to, the mySAP ERP software.”[1]
  • As regards the Connect customer software:
    • The interactions between the SAP ERP and Connect amounted to “indirect” access to the SAP ERP on the basis that each stage of the order process carried out through Connect involved transmissions between Connect and the SAP ERP and that Diageo’s customers (who were not ‘Named Users’ for the purposes of the SAP ERP) accessed or used SAP ERP indirectly through SAP PI when using Connect.
    • SAP PI was not a “gatekeeper” for access to other SAP applications. The charges for the SAP PI were in addition to, not instead of, named user charges for the underlying applications.
    • The court distinguished the Connect system from the previous system (in which Diageo Named Users would place orders in the SAP ERP) on the basis that there was no interaction between Diageo’s customers and the SAP ERP when orders were placed via the call centre – Diageo Named Users were interacting with the SAP ERP in that situation. Using Connect, however, involved access or use by Diageo customers of the SAP ERP indirectly through the SAP PI.
    • No ‘Named User’ category in the schedule applied to the type of access created by Connect to the SAP ERP as the Connect users “[did] not have access to source or object code. They [did] not have access to the functionality provided by mySAP ERP in support of the wider operation of Diageo’s business. They [accessed] business process functions and information from the database for the purpose of ordering products and managing their own personal accounts only.[2]
    • The amount of any additional licence fees due to SAP would need to be assessed during the damages phase of the trial.
  • For Gen2 the court reached a similar conclusion.
  • Therefore, SAP was entitled to charge Diageo for the access and use of the SAP ERP. The amount of such charges will be determined in a separate trial on quantum of damages unless SAP and Diageo reach a settlement as to the amount due or Diageo appeals the decision.

The issues at trial focussed solely on the terms of the agreements between Diageo and SAP. No claims of copyright or database right infringement were brought against Diageo and no claims based on representations as to the scope of the licence were brought against SAP.

The ruling in favour of SAP is likely to lead to increased scrutiny of the precise language used in contractual software licence grant clauses by customers and providers. Issues of this type are likely to become increasingly common as providers and customers grapple with the fast pace of technological development and the move towards cloud based, customisable, and interoperable IT systems easily accessed via APIs or browser interfaces.

We recommend therefore that particular attention is paid to the language used in Ts&Cs and how it may apply to different use cases or access rights. Customers should carefully review at the outset of the contract the nature and extent of the rights granted under any licence and the methodology applicable to the calculation of licence and maintenance fees. In these times of rapid technological change, customers should also consider putting in place a structured process to ensure that their use cases across the organisation continue to map to the licence grant and charging clause across the licence lifecycle. The issues for the software provider are the obverse – ensuring a genuine understanding by customers of licence scope and charging terms and backing up the primary contractual obligations with workable audit rights to verify compliance.

For both sides, contractual terms dealing with the following issues should be express, precise and clear so that each party is aware of its obligations:

  • types of user – what categories of employees and/or contractors require access?
  • nature of access – is it direct log-in via user ID or access via a plug-in, API or other specified indirect method?
  • type of access – is it merely pulling information from the customer’s database within the provider’s offering? does it involve use of the functionality provided by the software? If the latter, exactly what functionality is involved?
  • scope of licence – what rights are granted to each category of users? Is this linked to the nature and type of access?
  • will the contract software interact with other systems in a way that could give rise to licence scope or charging issues for the contract software or the contracts governing the other systems? This will become important as systems built around Artificial Intelligence (AI) and Robotic Process Automation (RPA) increasingly interact with each other indirectly, automatically and without direct human intervention.
  • how are the charges calculated? How frequently can the provider increase the charges?
  • what rights does the provider have to audit or verify the customer’s use of the software? How frequently can it exercise these rights? In what circumstances should an audit be permitted?
  • what changes does the customer intend to make to its IT estate over the life of the contract? Will any of these require changes to the rights granted by the provider and oblige the customer to increase amounts payable to the provider? Can any of these costs be reduced or will they ultimately be passed on to the end customer?
  • in what circumstances and on what terms can a customer terminate its licence? how easy is it for the customer to migrate from the incumbent system/software to that offered by a new provider if the charges payable to the incumbent provider increase dramatically? Will the costs of termination and transition be less than the increased costs payable to the incumbent provider?
