“We refer to our client’s application to strike out and/or for summary judgment dated13 January 2021 (the “Application”). In our letter dated28 April 2021 , we set out our clients’ position regarding the costs of the Application and that your clients, having abandoned their original competition defence (the “Abandoned Competition Defence”) which was the subject of the Application, must now pay our clients’ costs. We informed you that there were no grounds to resist an order for costs and that unless you indicated by return that this was agreed then our clients will be seeking an order for indemnity costs from the date of your letter of 20 April due to your unreasonable conduct. In your letter of 5 May, you stated you would revert separately on the issue of the costs of the Application. You have not done so and so there is no agreement. … We now enclose by way of service: 1. Our Statement of Costs, which includes the costs of the IP counsel in relation to work done considering issues raised in the Abandoned Competition Defence and in relation to the Application; and 2. Macfarlanes’ Statement of Costs, which includes the costs of the competition counsel in relation to the Abandoned Competition Defence and the Application. The enclosed Statements include all the wasted costs in dealing with the Abandoned Competition Defence since it was served and the Application, including the costs of considering the evidence and materials served on us on 31 March.”
