Sen (Alex) Wang is an Intellectual Property associate in Mayer Brown’s Washington DC office. Alex’s practice focuses on patent litigation in federal courts, the International Trade Commission (ITC), and post-grant proceedings before the US Patent and Trademark Office.
Enabled by his background in mechanical design, manufacturing, and automation, Alex has a quick grasp on a wide range of technologies and has litigated patents covering mechanical, electrical, and software arts in various industries, including medical device, clinical lab automation, electronic cigarettes, motion furniture and consumer electronics. Alex represents domestic and foreign clients of all sizes both offensively and defensively. In particular, Alex has represented clients from China, Japan, and South Korea.
In addition to performing pre-suit due diligence, crafting written discovery requests and responses, managing document production and review, drafting claim construction briefs and dispositive motions and preparing expert reports, Alex also steps out of his office to advocate for his clients, whether it is taking or defending depositions, conducting product inspections, or presenting oral arguments in front of judges.
Besides litigating patent disputes, Alex evaluates clients’ products and provides freedom-to-operate opinions. Alex also prosecuted patent applications protecting technologies such as drug-eluting stents, patient monitoring and drug titration system, commercial deep fryer, industrial filters, freight tie-down devices for trucking and high-pressure hydraulic valves.
Alex is active in providing pro bono legal services. He currently represents a non-profit entity in a trademark related matter. Before moving to Washington, DC, Alex served as a mentor for students at the Legal Prep Charter Academy in Chicago and was a volunteer at the Chicago Chinatown Pro Bono Clinic.
Born and raised in mainland China, Alex is a native mandarin speaker and received his graduate and undergraduate degrees from Peking University Law School and Harbin Institute of Technology, two top Chinese universities. Alex holds the Legal Professional Qualification Certificate issued by the Chinese Ministry of Justice after passing the National Bar Exam in 2011.
