Mark Platts-Mills QC


Year of call: 1975
Year of silk: 1995

After reading engineering and economics at Balliol College, Oxford, Mark Platts-Mills QC joined the pre-eminent patent and intellectual property set at the time, the Chambers of Mr. Thomas Blanco White at Francis Taylor Building. He has since specialised in all aspects of intellectual property including patents, trade marks, passing off, registered designs, copyright, design right, technical trade secrets and commercial matters with a technical content. Mark was characterised as a “real fighter” in Chambers Directory 2010 and indeed, Ultraframe v Eurocell is prominent among his recent highlights as one of very few fully fought out inquiries as to damages in a patent action. He has also recently represented the applicant for revocation of a UK patent which, if upheld, would have covered the ubiquitous USB memory stick (Trek v MSystems). In other highlights, Mark appeared for the defendant in the leading database right case (British Horse Racing Board v William Hill), and for the claimant in a successful trade mark infringement trial concerning tree shaped air fresheners (Julius Samann v Tetrosyl). In addition, he successfully represented the defendant in a design rights case relating to helmets for the rescue services (Helmet Integrated Systems v Mitchell Tunnard). He is currently representing the claimants in the trade secrets case Vestergaard Frandsen v Bestnet.

Clients can expect to benefit from Mark’s long experience encompassing an extremely diverse range of cases, which has given him a lasting appetite for the most challenging of disputes.

Confidential Information

Vestergaard Frandsen AG v Bestnet Europe Ltd and others (2015)

Leading Thomas Moody-Stuart and James Whyte for the Claimants. This dispute (which commenced in 2006) relating to trade secrets in the formulation of the materials from which Mosquito Nets are manufactured continues. The inquiry as to damages was heard in the summer of 2014. Both sides are appealing and an appeal is likely to be heard in late 2015. 

Specialist Marine Services v Dalby (2009)

Copyright and confidential information case concerning operating of ships out of Humber. Mediation settled.

The Gadget Shop v Bug.Com 2000

An application to set aside a without notice search order (Anton Piller). The claimant alleged that the personal defendants had filched a large amount of allegedly confidential information and on that basis obtained a search order. The search revealed virtually nothing and nothing of any substance. The Order was discharged after a six-day hearing on grounds that included material non-disclosure and serial breaches of CPR. The claimant had, among other matters, used an out-of-date version of the standard form search order.
