What E Blum does
E. Blum & Co. AG (referred to in firmographic data as "E Blum") is a Swiss intellectual property law firm founded in 1878 by Emil Blum and headquartered in the Franklinturm building at Hofwiesenstrasse 349, Zurich. The firm operates as a Swiss Aktiengesellschaft (CHE-107.825.798) and has functioned continuously for over 145 years as one of Switzerland's leading patent and trademark attorney practices. It is privately held with no disclosed parent company, subsidiaries, or institutional shareholders.
The firm's service offering covers the full spectrum of intellectual property law, structured into roughly fifteen core practice areas: patent prosecution and litigation (including opposition and appeal proceedings before the European Patent Office and the Swiss Federal Patent Court), trademark registration and portfolio management, design protection, domain name registration and disputes, copyright (including software and open-source licensing), freedom-to-operate and prior-art searches, license agreements and IP assignments, R&D contracts, IP litigation and infringement proceedings, IP due diligence for M&A, IP strategy consulting, Innosuisse coaching for start-ups and scale-ups, Swiss patent box tax advisory, and ongoing IP portfolio administration. Underlying this practice, the firm claims specialist technical coverage across 40+ technology domains including artificial intelligence and machine learning, quantum computing, blockchain, cryptography, biotechnology, pharmaceuticals, medtech, MEMS, nanotechnology, and advanced engineering disciplines.
The business model is fee-based professional services delivery, with quoted engagements following free 20-minute initial consultations booked online via Calendly. The team comprises approximately 14-15 named senior professionals (partners, patent attorneys, trademark attorneys, and attorneys-at-law) supported by paralegals and an IT administrator. Many attorneys hold PhDs, sit part-time as judges at the Swiss Federal Patent Court and commercial court, teach at ETH Zurich, ZHAW, and CEIPI, and have prior in-house IP experience at IBM Research Zurich, Philips Intellectual Property & Standards, Siemens, and Sicpa Holding. The firm serves innovative companies and individual inventors across Swiss industries, with no named customer logos disclosed and no geographic footprint beyond Switzerland.
