John Clayton Mewburn began work in London in the 1860s, joining with George Beloe Ellis in the 1890s to form a firm which became Mewburn Ellis & Co. Six members of the Ellis family have been partners in the firm. George Ellis' daughter, Margaret Dixon, became the first woman to practise as a UK patent agent, and her brother, John Ellis, retired from the partnership in 1988. 

As you might expect the firm has gone through many changes, but through fluctuations in the economy and rapid advance of technology the firm has thrived.

Now we are a modern, forward-thinking firm handling all aspects of intellectual property, with offices in central London, Bristol, Cambridge and Manchester. We have clients all over the world and the knowledge and expertise to handle intellectual property portfolios of all types and sizes. The number of partners has grown along with the size of the firm.

Our patent and trade mark attorneys are qualified to deal with both UK and European patents and trade marks and are accustomed to managing worldwide portfolios for our clients. We also have a team of in-house specialist lawyers who have many years of experience in the areas of licensing, assignments, technology transfer and due diligence in particular.
