The barristers at 11 South Square showcase combined expertise in intellectual property and telecoms disputes, often acting for major clients in cases with a crossover element. Appearing before the Court of Appeal, Michael Silverleaf KC acted for the Ministry of Defence in IPCom v Vodafone, intervening with the agreement of the parties, regarding the crown use provisions of Patents Act 1977; the case involves a technology that can be used to prioritize emergency services users over the mobile phone network. In Philips v Xiaomi, Mark Vanhegan KC represents the claimant in connection with patents declared to be essential to 3G and 4G standards. Vanhegan also went up against Brian Nicholson, who represented the defendant, in Facebook v Voxer, a dispute focused on a patent revocation action.
Regarded as ‘one of the top IP sets at present‘, 11 South Square acts for film studios, musicians and music producers in a range of copyright and trade mark infringement challenges, with further expertise in royalty disputes and contractual breaches. Hugo Cuddigan KC, considered a ‘top-drawer‘ silk, acted in Sheeran v Chokri, a High Court claim for negative declaratory relief by Ed Sheeran concerning his song “Shape of You” following allegation the song was plagiarized from the respondent’s 2015 song “Oh Why”. Representing the high-profile streaming service, Mark Vanhegan KC acted in In EasyGroup Limited v Netflix Inc and Swanberg, a High Court trademark infringement dispute relating to Easy, a Netflix comedy-drama.
The ‘best intellectual property set around‘ for many, 11 South Square is consistently involved in the market’s leading IP cases, including an enviable number of high-profile first instance trials and appeals. Recent highlights include Iain Purvis KC‘s representation of Ocado in a substantial Patents Court action concerning Autostore’s patents for automated warehousing technology; and in one of the one of the most talked-about patent cases of recent times – Neurim v Mylan, an ongoing dispute involving Neurim’s prolonged-release melatonin formulation used to treat insomnia, Circadin – Mark Vanhegan KC appeared as lead counsel for Mylan in the Patents Court on a preliminary injunction application. This was subsequently followed by an expedited appeal of such decision to the Court of Appeal, along with an expedited trial of the main action. The rising star juniors to note are Mitchell Beebe and Kyra Nezami, who are both increasingly involved in high-profile IP cases.
