Alex Magnusdottir

Overview

Alex Magnusdottir is an associate in Kirkland’s Intellectual Property Litigation Team in London. Alex is experienced in litigation covering a wide range of technical fields, but has a special interest and experience in life sciences patent litigation, particularly in the pharmaceutical industry. With a PhD in Neuroscience, Alex is well placed to advise life sciences clients on their most technical subject matters, and her patent litigation experience covers a broad spectrum of technical subject matters, including those relating to biologics, antibodies, prodrugs, emerging gene therapies, medical devices (cochlear implants) and drug-device combinations. Alex also advises clients in complex global SEP/FRAND disputes between leading companies in the telecommunications industry.

Alex’s litigation matters often cover disputes in multiple jurisdictions, and her experience extends to the coordination of global disputes and pre-litigation readiness at a pan-European scale.

Alex also has a significant non-contentious IP experience, advising on the patent and life sciences regulatory aspects of transactions, as well as the broader intellectual property rights, including trade mark rights.

Since joining Kirkland, Alex has been involved in the following matters:
