A legacy of innovation
We are a leading intellectual property law firm, combining deep technical expertise with commercial insight to support innovators across a wide range of industries.

For 25 years we have been building a leading IP firm and today we bring global expertise in transforming legal safeguards into powerful competitive advantages.
Over the years, we’ve built a reputation as a strategic, forward-thinking IP firm with deep expertise in complex patents. Our strength lies in our multidisciplinary and collaborative approach, bringing together litigators, patent attorneys and commercial IP lawyers to deliver high-value advice internationally. We also excel in managing global portfolios and driving innovation in new technology areas.
We were founded in London in 2000 by Jerome Spaargaren, whose work in patent law quickly gained recognition for its clarity and strategic depth.
His reputation led to early collaborations with major clients, setting the foundation for the firm’s growth. Several members of our current board joined Jerome in those early days, bringing together experience from both private practice and in-house roles at multinational companies. EIP was built on a shared vision: to deliver technically rigorous, commercially strategic intellectual property advice across the full lifecycle of innovation.
From a single London office, we expanded steadily:
2006
2007
2010
2011
2013
2014
2022
We have now grown to over 180 staff, including 34 partners, with offices in the UK, Germany, Sweden, and the US. Our growth has been driven by a combination of technical excellence, strategic insight and client trust.
At EIP, we are committed to reducing our environmental impact and contributing to a more sustainable future. Through our internal initiative, eMission, we actively review and improve our practices across energy use, travel, procurement and digital infrastructure.
We are also proud to be members of the IP Charter for Energy Transition (IP4ET), which promotes decarbonisation across the IP supply chain.We have also signed the World Lawyers' Pledge on Climate Action.
Together we aim to:
Measure and manage our carbon footprint
Reduce emissions at the source
Extend the lifecycle of company devices
Explore offsetting and carbon capture solutions

We believe sustainability is not just a responsibility but an opportunity to innovate, collaborate and lead by example. Our efforts are guided by client expectations, industry benchmarks and a shared desire to make a positive impact.
