Gill Jennings and Every LLP

The firm is comprised of European patent and trade mark attorneys, who advise on patents, trade marks, designs, data exclusivity rights and plant variety rights.  Our patent expertise covers the whole range of industry sectors, including electrical and mechanical engineering, physics, IT/software, business methods, chemistry, life sciences and medical devices.

The importance of IP rights within the biotechnology sector cannot be overstated. Biotechnology is generally a field which experiences rapid technological advancement but where there is also a significant lag in financial returns for investors.  Innovation in this sector is a complex process and success in the early stages carries a significant level of financial risk. Securing, as well as maximising, the financial gains from innovation within the biotechnology sector through the correct deployment of IP rights is therefore essential.

These are issues which the attorneys at GJE fully understand. Our patent and trade mark attorneys have decades of experience developing and implementing tailored IP strategies to help ambitious and innovative biotech companies of all sizes achieve commercial success. Our clients value the intelligence and creativity of our attorneys, and the commercial approach to identifying, protecting and exploiting IP that is fundamental to our philosophy.

The technical expertise of our Biotechnology team covers all aspects of biotechnology, including pharmaceutical and industrial biotechnology, regenerative medicine, diagnostics and immunology. In addition to strong academic backgrounds in biosciences, our attorneys have significant industrial experience and understand the legal, technical and commercial challenges faced by companies in the global biotechnology sector. We support our clients with a complete range of IP services, including invention capture, patent drafting, filing, prosecution, opposition and appeal, supplementary protection certificates (SPCs), plant variety rights, due diligence and freedom-to-operate.

We also provide strategic advice, from assisting with developing a business plan through to ensuring IP portfolios are structured with the commercial goals in mind, be that to attract private equity/VC funding, secure licensing deals, float on a public market or exit via a sale. We have a track record of supporting clients preparing for IPO and we have advised on a number of successful trade sales.

Our Biotechnology team represents a diverse range of clients, including many UK and European start-ups and SMEs, as well as established multinationals. We aim to form long-term relationships with all of our clients, and to become their trusted advisors. Part of this is helping clients to establish their own internal procedures. Our bespoke client portal provides access to up-to-date case data and is an invaluable tool for those managing large or complex IP portfolios.

Having many direct clients means that we manage the prosecution of patent applications all over the world, with the support of our network of overseas attorneys. As a result, we are experienced in navigating the legal complexities presented by the nuances of patent law in foreign jurisdictions, which can be particularly challenging in the biotechnology field. We also prosecute a large number of agency cases and help to secure and defend UK and European patent rights for International biotechnology companies.

We are consistently recognised by the leading UK legal directories, Chambers, Legal 500 and Managing Intellectual Property, a testament to the quality of our advice and the valued role we play in supporting our clients.
