Firm overview

At Greaves Brewster we’re proud to have a distinct approach, mindset and location. It means we’re able to do things a little differently. It also might be why our clients say that we’re the most open, transparent and easy to deal with IP practice out there. We believe every interaction with your attorneys should be simple and straightforward.

We are committed to providing excellent, client-driven service and to enjoy doing so. Our aim is to add value to our clients’ businesses, whilst charging a fair price for our work. We believe in working efficiently, utilising technology and simplifying processes wherever possible. We are flexible, we adapt to our clients’ needs, rather than expecting them to fit in with our way of working.

We are experts in all aspects of IP prosecution, including drafting, filing and prosecuting patent, trade mark and design applications, as well as strategic management of our clients' IP portfolios. We are sought out for our experience of oppositions and appeals and are well known for providing clear cut, commercially relevant advice, particularly in relation to freedom to operate and due diligence.

We believe that it is possible to be successful whilst still acting in an ethically sound and satisfying manner. Whilst we continually act to maximise our clients’ business gains, when it comes to measuring our success, we do not believe financial gain to be the most important factor. We are committed to supporting the practice diversity of our staff, encouraging them to work on matters that are valuable and intellectually stimulating, as well as financially rewarding. We actively choose to work with clients and companies who share our purpose.
