Carpmaels & Ransford LLP

TMT (technology, media and telecoms) > PATMA: Patent attorneys Tier 1

Carpmaels & Ransford LLP integrated its growing materials practice into its wider chemistry team under the lead of Gillian McGuire to advise on matters at the intersection of the two specialisms, often for consumer product clients. In Gary Small‘s engineering and technology team, the caseload increasingly includes AI and machine learning patents. The well-known medical device practice has remained a core area for the team. In the life sciences, a key area of expertise for the firm, the practice saw the biggest organic growth, with biotechnology practice head Mark Chapman and pharmaceuticals practice head James Warner raising two attorneys each to senior associate level and life sciences expert Anna Leathley and Isobel Barry, who focuses on pharmaceuticals patents, joining the partnership in July 2021. John Brunner is also active in technology issues. Across the teams, the practice advises on the entire life cycle of a patent, starting with invention mining, EPO opposition matters, and ending with enforcement matters for which clients can draw on the firm’s team of solicitors. Hugh Goodfellow is the firm’s managing partner; former post-holder Richard Jackson retired in June 2020. In July 2020, solicitor and biotechnology and pharmaceutical specialist Jennifer Antcliff made partner.

I have worked with a dozen European patent firms and none can match the synergy of the people (partners and associates) of Carpmaels. Their expertise, their dynamism, the energy to tackle problems and find solutions, and their ability to achieve success is incomparable to other firms. Exceptional use of technology. Exceptional collaboration with the client. Carpmaels offers and produces exceptional advice and outcomes.

Carpmaels has a terrific team of partners and others with wide and deep experience in pharma. We not only benefit from their knowledge in prosecuting patents, but also rely on their advice relating to general strategy, opposition proceedings, and regulatory issues.  Carpmaels has a team dedicated to national validations that we employ regularly.  Carpmaels also has a team dedicated to SPC’s which we also take advantage of.  Rarely is there a need to seek advice elsewhere.

Carpmaels & Ransford has a strong IP litigation team.  The team is experienced in both UK and EU litigation matters. In particular, I would engage Carpmaels for multi-jurisdiction litigation involving both US and UK. In addition to having a global view, and the team has a solid understanding of US legal procedures.

I have mostly worked with James Warner and Hazel Turner, both of whom are outstanding in their knowledge and service.  James, despite being a busy partner, always has time for our questions and personally communicates with us regularly.  Hazel has a depth of knowledge that we tap into constantly regarding pharmaceutical patents.

John Brunner is a rising star with in depth knowledge in pan-European patent matters. John has delivered consistently positive outcomes.
