Sara Ashby

Partner at Wiggin LLP

Sara Ashby is an IP litigator and head of the firm’s IP practice. Strategic and tenacious, she advises on patent enforcement and strategy, and has more than 20 years’ experience litigating patents and other IP rights. She is particularly adept at the ‘non-standard’, her broad experience coming to bear in complex patent cases that involve other IP rights and contractual disputes.

As well as litigating in the English Patents Court and the Court of Appeal, Ms Ashby has considerable experience in the Shorter Trials Scheme and Intellectual Property Enterprise Court, which have streamlined procedures and different costs regimes.

Ms Ashby is equally comfortable acting for claimants and defendants – whether multinationals or owner-managed businesses – no matter where they are based, in standalone litigation or matters involving parallel proceedings in other jurisdictions. Her clients hail from diverse sectors, including medical devices, automotive, optics and general engineering. Recent wins include invalidating a patent with a certificate of contested validity, relying on the same prior art (Emson v Hozelock (expandable hoses)); invalidating the patent relying on the inventor as expert to prove obviousness and insufficiency (Coloplast v MacGregor (catheters)); and obtaining indemnity costs and novel compensation for currency exchange losses resulting from Brexit (Saint Gobain v Elkamet (automotive)).

Ms Ashby is president of AIPPI UK, the national group of the International Association for the Protection of Intellectual Property – a cross-profession international leading non-government organisation for research into, and formulation of policy for, the law relating to the protection of intellectual property.

Ms Ashby was an assessor to Lord Justice Jackson in his review of fixed recoverable litigation costs, a contentious area of law reform, and involved in writing the capped costs pilot scheme rules for the business and property courts.

She is heavily involved in Oxford University’s postgraduate diploma in IP law and practice, lecturing on IP litigation, and tutoring and examining on designs law. She has served on the Diploma Management Committee for many years. She is a research fellow at Oxford University’s IP Research Centre.
