A “chemistry ace” according to commentators, Anna Hatt impresses clients with her “sharp mind”, careful forward planning and firm technical grasp. Her skills are on show in a variety of fields, from aquaculture to semiconductors.


Anna is a patent specialist with a background in chemistry which has blossomed into wide-ranging industry experience. Experienced in drafting, prosecution and opposition advice before the EPO and UKIPO, she is particularly valued by clients for a level of thoroughness and expertise that means they “really feel safe that everything and all angles of a case will have been properly considered.”

Patent expert Anna enjoys handling a wide variety of subject matter, including food production and packaging, aquaculture, printing materials, polymers and semiconductor manufacture. Coming from a medical family, she also has a particular interest in medical devices.

Anna assists clients with patent drafting, prosecution and opposition work and provides advice on patent infringement and validity. As market commentators have noted, she has an impressive success rate in opposition and appeal hearings, where her skill in finding gaps in the argumentation is invaluable. She is also highly experienced in representing clients at the EPO and UKIPO, where she’s demonstrated a keen understanding of the EPO’s new arrangements for videoconference hearings adopted under Covid. Her clients, many of which are based in the Nordic region, include companies from start-ups to household name multinationals, as well as an NHS trust.

Anna also has a notable interest in patent education. A regular contributor to the CIPA Guide to the Patents Acts, the standard reference text for UK patent attorneys, she edits a monthly update on UK patent case law for the CIPA journal and has been recognised for this with a CIPA Journal Editor’s Award. In addition Anna designs and runs training courses on patent skills for the patent department of an important client and presents webinars on UK and European Patent law for specialist and non-specialist audiences.

"Anna Hatt is a go-to patent attorney. She provides clarity about costs upfront, works fast, and delivers a high-quality product."


Anna is recommended in The Legal 500 UK 2024, IAM Patent 1000 2023 and she is recognised as an IP Patent Star by Managing Intellectual Property 2023.

“John Hull, Catherine Jewell, and Anna Hatt are excellent patent practitioners, and they particularly stand out for their ability to apply European patent law to navigate complex opposition issues.”
Client testimonial, Legal 500 UK 2024

“Anna Hatt has successfully opposed several of our competitors’ patents, and defended a couple of our patents against opposition. She puts her arguments together in a logical and clear way that is easy to read and understand. She’s very detailed and dives into the matter and asks very good questions. She is very good at getting things precisely right. She understands the technology as well as the method and does a great job. She has impeccable drafting. I would definitely recommend her to others; above all, I would recommend her and Beck Greener to clients looking for a good track record in oppositions, appeals and oral proceedings at the EPO.”
IAM Patent 1000 2023

“We work with Anna Hatt (and Deborah Selden). Both are solidly reliable and knowledgeable with sharp minds, able to understand technical matters in depth and apply what is needed for success. They also don’t shy away from finding extra prior art etc when there are gaps in the argumentation. Anna plans well ahead and acts immediately on all matters, such that you really feel safe that everything and all angles of a case will have been properly considered and dealt with.”
Client testimonial, Legal 500 UK 2022
