Gill Jennings & Every LLP (GJE) is a leading firm of European patent and trade mark attorneys which combines a relentless focus on high-quality IP services with an innovative approach to providing strategic and consulting advice to clients and investors. 

Our world-wide corporate and foreign attorney clients value the efficiency of the service we provide in acquiring and maintaining their and their clients’ IP rights as effectively as possible. We ensure the right combination of quality advice, fast processes, and technology to give clients the right support for their needs. Our ability to manage large portfolios and keep clients informed of their IP rights is highly regarded, whether using our own technology such as our well-regarded Client Portal, or updating our clients’ databases directly. Our own service standards and processes combine with individual Service Level Agreements to ensure we provide the types and levels of services our clients expect.

We believe that the IP law industry is changing, and so our vision is to provide a higher level of commercially-minded business consultancy in addition to our expert legal and technical advice. We are widely recognised for our commercial acumen and regularly work with leading corporate lawyers and accountants in handling strategic IP issues, and have developed new IP services designed to ‘future proof’ our client businesses. Marketed as ConsultIP™, those services put IP at the centre of business strategy rather than in its traditional place as an ancillary concern. Through ConsultIP™, we provide a full range of support for patent, trade mark and designs portfolios, including an objective review of the value of those portfolios, to help clients exploit their investment, and attract further funding for their ventures. 

Our strong reputation in Oppositions, whether defending our clients’ rights or attacking our opponents’ claims, is built on a record of wins which is second to none. In the last five years we have achieved significantly higher success rates, with 57% of all cases opposed by us during this period being revoked, and only 14% being maintained as granted, compared to the EPO oppositions average of 39% and 29% respectively. Similar levels of success have been achieved in defending clients’ patents, where we have maintained 31% of patents as granted, against a UK firm average of 22%.

Our client bank includes global corporations, foreign attorneys, small and medium-sized enterprises (SMEs), early-stage/spin-out companies, universities, and individual inventors. 

Our attorneys offer a broad range of technology-agnostic skills, in addition to our core specialist expertise in engineering, physics, IT/software, electronics, life sciences, medical technologies and chemistry.
