What keltie does

Keltie LLP is a UK-headquartered intellectual property law firm founded circa 1991, operating from five offices across the United Kingdom (London, Cambridge, Cotswolds) and Ireland (Galway, Dublin), with the Irish offices providing post-Brexit access into the EU IP system. The firm delivers patent, trade mark, design, and online brand protection services before the European Patent Office, EUIPO, UKIPO, Irish Patents Office, and WIPO, and serves multinational corporations, universities, SMEs, startups, and individual inventors. Keltie is structured as a private limited liability partnership owned by its partners, with no evidence of external institutional investment or parent ownership.

The firm's core product is professional IP advisory organised into specialist technical practices: AI & Quantum, Advanced Materials & Manufacturing, Sustainability, Life Sciences & Chemistry, IT/Telecoms & Electronics, and Engineering. Service lines cover the full patent lifecycle (drafting, search, filing, prosecution, opposition and appeal), trade mark and design registration and enforcement, online brand monitoring, customs protection, and strategic IP consulting including UK Patent Box tax advisory. Delivery is direct and consultative through qualified attorneys, with global coverage coordinated through a foreign associate network; revenue is generated on a quote-based, multi-year professional services engagement model.

Keltie's talent base includes PhD-qualified attorneys across physics, engineering, chemistry, and biotechnology, and the firm claims one of the largest quantum patent teams in the UK alongside early-mover credentials in quantum patenting. The firm has accumulated multiple elite analyst rankings in 2026, including a Gold clean sweep across every category of the FT Europe's Leading Patent Law Firms rankings, IP STARS, IAM Patent 1000, WTR 1000, Chambers UK, and WIPR Leaders, positioning it among only eight European firms with cross-field patent excellence recognition.
