A Patently Global Mindset
Felix Einsel has built a career — and a life — around crossing borders, which has found him as managing partner at a law firm strongly branded in multiculturalism.
A patent attorney based in Japan, Einsel occupies an unusual space in the global legal world: deeply rooted in a Japanese-based practice, yet shaped by German heritage, international education and decades of experience working across cultures. Part of his education occurred at UW Law, where he earned his LL.M. in 1993 en route to sitting for the New York Bar, in which he remains an active member. Why New York? “At the time,” said Einsel, “with an LL.M. you were only permitted to sit for the bar in New York and California, and I felt like New York would be another addition to my cultural education.”
In conversation, he comes across as both pragmatic and reflective, someone who sees intellectual property not just as a legal specialty but as a lens on how societies work, how businesses build trust and how people learn to navigate differences.
Einsel’s family history helps explain that outlook. His father, born in Berlin in 1927, was held prisoner by the Americans on the Western Front in the final days of WWII. He went on to study law in Germany and eventually made his way to Japan by ship in 1956. The family’s connection to patents and cross-border work also includes Felix’s uncle and two cousins. Einsel describes that legacy not as destiny but as inheritance: a family culture in which law, mobility and multilingualism were part of the background.
As a sidebar, Einsel notes that one of his father’s hobbies was genealogy, and he’d managed to trace the Einsel name back to 12th-century Switzerland. “Today,” Felix said, “there are not that many Einsels left in the world, and including me, three of them are patent attorneys.”
He was born in Japan, but raised between Japan and Germany, attending German-speaking schools in Japan. That early experience gave him a perspective that would later define his career. He learned to move between languages, customs and legal systems almost instinctively. Today, he still spends several months each year abroad, and he says his personal and professional world remains international by design. English, German and Japanese all sit alongside one another in his daily life.
His path into patent law was shaped by both family influence and curiosity. As a child, he listened to relatives speak about licensing, industry and the differences between Western and Japanese business culture. He became fascinated by the combination of technology and law, and in school he gravitated toward science — biology, physics and chemistry — while keeping an eye on the legal world. The result was a career that would combine technical fluency with legal judgment and cultural translation.
Einsel’s route into Japanese patent practice was anything but straightforward. At the time, becoming a Japanese patent attorney was restricted to Japanese nationals and he faced a licensing barrier that could have ended the plan entirely. Instead, he found a creative solution grounded in reciprocity: if a Japanese national could be registered in Germany, he argued, then he should be registered in Japan. “Looking back,” said Felix, “the whole plan seems a bit bold. But the strategy worked, and just weeks later the nationality requirement was abolished.” This anecdote is a consummate example of the resourcefulness that has marked his career.
He also studied at the University of Washington School of Law, drawn there by the strength of its intellectual property program and by the reputation of Donald Chisum, the influential IP scholar. Einsel remembers the school as open and accessible, with professors who made time for students and a collegial environment that left a lasting impression.
Afterward, he sat for the New York bar, another step that reflected his willingness to keep expanding his horizons. “My career arc has truly been defined by continuous learning, driven by the need to stay current with rapidly changing technologies and diverse legal systems,” said Felix. That is especially true in patent prosecution, where he works across jurisdictions and advises clients filing in Europe, the United States, China, Canada and beyond. In that field, he says, the attorney must not only understand the law but also remain alert to technological change and the cultural habits of clients and courts.
Much of Einsel’s thinking about law is shaped by culture. He argues that patent practice is never purely technical. In Japan, he says, the legal system, the courtroom culture and the negotiation style all reflect a preference for patience, careful relationship-building and indirect resolution. He has seen how Japanese companies often avoid litigation unless necessary, how warnings can open the door to settlement, and how trust is built slowly over repeated meetings. For him, the real work of patent law lies not just in drafting and enforcement, but in understanding how systems and people behave differently across countries.
That belief also informs the way he runs his firm. The practice was founded in 1910 by lawyers from Germany, Australia and the UK, making it one of the oldest foreign-founded firms in Japan. Its history includes war, migration and survival under extraordinary circumstances. Einsel says the firm endured because it was built on multiculturalism long before that word became common in corporate life. Diversity, in his view, is not a slogan but an operational advantage: it improves communication, broadens perspective and makes the firm more effective in international work.
He has tried to extend those values beyond his own practice. Several years ago, he started a foundation to support multicultural candidates for the Japanese patent attorney exam. He sees potential in young people who have grown up between countries, and he encourages them to imagine careers that do not fit conventional templates. For Einsel, the future of legal work depends on exactly that kind of cross-cultural adaptability.
He is not naïve about the pressures facing the profession. He worries about the impact of artificial intelligence on learning and judgment and he is skeptical of the way new technologies are sometimes sold as inevitable fixes. But his response is not to retreat. Instead, he talks about responsibility: to clients, to students, to younger lawyers and to society more broadly. “The point,” he suggests, “is not simply to survive change but to shape it thoughtfully.”
That may be the clearest portrait of Felix Einsel: a lawyer who has spent his life moving between systems and who sees that movement as the work. He is a patent attorney, yes, but also a bridgebuilder, a teacher and a custodian of a family and professional tradition that has always depended on understanding more than one world at a time.
