Anthony entered the patent profession in 2009, initially working at a large agrochemical company, before moving into private practice in 2015. During his time in private practice, Anthony has also worked on secondment for a biotechnology company in Switzerland and an academic institute in the UK.
Before entering the patent profession, Anthony worked as a process chemist in the pharmaceutical and nutraceutical fields. As an attorney, Anthony has developed his experience across a wide range of technologies, focusing on small molecule chemistry in particular (including synthetic processes and formulation).
Anthony has experience across all aspects of patent practice, especially drafting, freedom to operate analyses and patent prosecution, both before the European Patent Office and throughout the world, and has also been involved with the management of large patent portfolios.
Anthony joined Keltie as a Director in 2023.

The Effect of the Unified Patent Court (UPC) on Opposition Proceedings at the European Patent Office (EPO)The introduction of the Unified Patent Court (UPC) has brought significant changes to the European patent landscape. This article, written by Nathaniel Taylor (of Keltie's Opposition and Appeals team), takes a closer look at the impact of the UPC on opposition proceedings at the European Patent Office (EPO). The article draws on a full year's worth of opposition data - available as of 1 April 2025 - for European patents granted since the Unitary Patent system began (i.e., European patents granted between 1 June 2023 and 1 June 2024). The analysis explores overall trends, technology-specific patterns, and the strategic motives behind relative opposition rates.
