What Gill Jennings & Every does
Gill Jennings & Every LLP (GJE) is a private English limited liability partnership headquartered at The Broadgate Tower, 20 Primrose Street, London, with a Munich office operated through GJE Germany GmbH under an alliance with German firm Wächtershäuser & Hartz. The firm provides specialist intellectual property legal services across three core practices — patents, trade marks, and designs — delivered through nine service areas: Patents, Trade Marks, Designs, Life Sciences & Biotech, Chemistry & Pharma, Computer Technology & AI, Physics & Engineering, Industrial Design & Consumer Products, and Branding & Trade Marks. The firm is regulated by IPReg and its European patent attorneys by the European Patent Institute (epi). GJE is governed by a Managing Committee led by Chairman Alasdair MacQuarrie, Managing Partners Stephen Haley and Michael Lord, and Practice Director Jenna Massey.
GJE's client base spans large multinational corporations (household-name names in telecommunications, telecom equipment, smartphones, software, pharmaceuticals, consumer brands, and music production equipment), academic institutions commercialising technology, growing SMEs, and start-ups across sectors including life sciences, climate tech, audio products, beverages, sportswear, and photography equipment. The firm earns revenue through professional services fees for IP prosecution, litigation, opposition, freedom-to-operate analysis, and IP due diligence, billed on time-cost or fixed-fee arrangements. Go-to-market is sales-led, driven by direct attorney-client engagement, legal directory rankings, client referrals, industry events (Advanced Materials Show, Agri-EPI Centre conferences), webinars, content marketing, and a client access portal.
Underlying capability rests on partner-attorneys with PhDs and advanced engineering/science degrees across multiple technical disciplines, supported by an operations layer (IT Director, Heads of Accounts, Records and Formalities, Operations, HR, and IP Support Managers) running Inprotech practice management and IT systems. The firm has held the Financial Times' No.1 ranking among European patent law firms for eight consecutive years as of 2026, with gold rankings in IAM Patent 1000 2026, recommendations in IP Stars 2026 and World Trademark Review 2026, and individual partner recognition in WIPR and Legal 500. The firm maintains dedicated Japanese and Chinese client landing pages, indicating active cross-border servicing into East Asia.
