Methodology

The list is composed of the most recommended patent law firms for services around patent prosecution and patent strategy consultation in Europe. It is based on an online survey of patent attorneys working in patent law firms and as experts in the patent departments of companies (peer-to-peer survey); and clients who have consulted with or commissioned a patent law firm.

Survey and sample

More than 10,000 patent attorneys and clients were invited to take part in the survey. The sample was collected via research conducted by Statista on company websites, in publications, and from the Institute of Professional Representatives before the European Patent Office, the professional body representing European patent attorneys. Patent attorneys and clients could also participate via a link on FT.com.

Participants could recommend patent law firms in general, as well as for six selected sectors: Chemistry & Pharmaceuticals; Electrical Engineering; Mechanical Engineering; Biotechnology & Food; Materials & Nanotechnology; IT & Software.

The survey was conducted February 8-March 27 2022. The recommendations of more than 3,200 clients and peers were considered. Self-recommendations and attempts to participate multiple times were prohibited and not taken into consideration.

Top lists

Firms are selected based on the number of recommendations. In total, 167 firms made it into the overall top list.

Firms that were highly recommended for their services in one of the six selected sectors were ranked in three classes: gold (very frequently recommended), silver (frequently recommended), and bronze (recommended).

All lists were created through a complex process. However, the quality of firms that are not included is not disputed.
