The main courts for England's intellectual property disputes sit in the City of London. The Patents Court, the Intellectual Property Enterprise Court and the rest of the Chancery Division work from the Rolls Building on Fetter Lane, so a trade mark fight between two Yorkshire breweries or a patent case between pharmaceutical giants ends up a few streets from St Paul's. The firms that litigate there range from the City's largest practices to specialist boutiques, and the choice between them mostly depends on the size of the claim: the Enterprise Court caps recoverable costs and limits damages to £500,000, which suits a smaller business, while the Patents Court has no such ceiling.
The Square Mile's own intellectual property is less visible than a brand on a shelf but worth more. Fintech companies around Liverpool Street and the insurers of Leadenhall live on software, data, algorithms and the trade marks of funds, platforms and syndicates; what they most often need is a solicitor to make sure the code their contractors wrote was assigned, the licences in and out are watertight, the brand was cleared before launch and the confidential information stays confidential when a team leaves for a rival. Artificial intelligence has added questions about who owns a model's output and what training data can lawfully be used, which City of London firms answer case by case.
For smaller City businesses, the restaurants, barbers, tailors and shops that serve the commuters, the work is the familiar kind: registering a name, dealing with a copycat, licensing a design. Most infringements end with a letter before action; registrations and standard agreements are fixed-fee, litigation hourly, which is why early advice pays.
