Take-Two Interactive Software Inc v Nathan James [2020] EWHC 179

The Patents Court has granted the developers and publishers of Grand Theft Auto V summary judgment for breach of contract, inducing breach of contract and copyright infringement, against two individuals who were involved in the development and sale of cheat software for use with the GTA video game.


The claimants sought summary judgment on the basis that the defendants had: (a) breached various GTA terms and conditions; (b) knowingly induced breaches of contract by the users of the defendants’ Epsilon mod menu; and (c) the defendants infringed copyright by authorising infringements of copyright in the form of copying and adaptations committed by Epsilon users.


  • Breach of contract – There was a clear breach of contract, as the EULA expressly prohibited both cheating in any form and providing guidance or instructions to another on how to cheat.  Yet the judge was not prepared to grant summary judgment against one of the defendants on this ground, as he was under 18 at the date when he first used GTA.
  • Inducing breach of contract – All five elements of the test in OBG Ltd v Allan [2008] 1 AC 1 were present: (a) there was a breach of contract by anyone who bought the Epsilon mod menu and used it on GTA, while bound by the EULA; (b) there was persuasion, procurement or inducement by the defendants, causing that breach of contract; (c) there was the requisite knowledge on the defendants’ part that they were inducing a breach of contract; (d) they intended to procure a breach of contract; and (e) the claimants had suffered damage.
  • Copyright infringement – The judge was satisfied that, by providing the Epsilon cheat software to consumers, the defendants had authorised the copying of the GTA program or substantial parts of it, without a licence.


Although this was a summary judgment application and the defendants represented themselves, the case usefully illustrates the causes of action and related issues that may arise from the unauthorised supply of software that alters the operation of a video game.  The defendants admitted that they had entered into a contract, but even if they had not done so, the court would apparently have been prepared to find that they had the requisite knowledge and intention, at least to the extent of turning a blind eye.  As such, the case gives some encouragement to rights-holders seeking swift justice. 

Some issues in the case will, however, remain unresolved.  There were also copyright arguments raised which the judge was not prepared to rule on definitively.  One was a potentially weaker claim that Epsilon circumvented the GTA technological protection measures to prevent unauthorised tampering.  Another was the claimants’ primary copyright infringement claim that the defendants themselves copied parts of the GTA program, and made unauthorised adaptations.  Those will now be matters for another case and another day.
