Its service offering is organized around core IP disciplines — patents, trade marks and brands, designs, litigation and dispute resolution, commercial IP and contracts, copyright, trade secrets, due diligence, freedom-to-operate, EPO oppositions, European patent validations (covering up to 43 countries), anti-counterfeiting, open source compliance, domain names, plant variety rights, and standard essential patents — overlaid with sector practices spanning life sciences, digital transformation (AI, blockchain, quantum computing, extended reality, 3D printing), aerospace and space, energy and environment, agritech, defence, and universities/spin-outs.
The firm generates revenue on a professional services model through hourly and fixed-fee billing to a diversified client base ranging from startups and universities to global multinationals. Distribution is delivered via 15 direct offices across three continents plus client liaison coverage in Japan and Korea, supported by a multi-language digital presence (English, French, Simplified and Traditional Chinese, Korean, Japanese). Key go-to-market assets include a content-led thought leadership engine (insights blog, IP Driven Start-up podcast, events, newsletters) and a multi-jurisdictional coordination model that delivers single-point-of-contact case management for complex cross-border filings and oppositions, evidenced by outcomes such as a 63% EPO patent revocation rate versus a 27% industry average, 70+ UPC litigation representatives, and consecutive top-tier analyst rankings (Legal 500, Chambers, IAM Patent 1000, WTR 1000, MIP, Financial Times) across multiple years and geographies.
