Masahiro Asamura is Managing Partner at Asamura Patent Office, p.c. and also represents Asamura Law Offices.
As a patent attorney, Mr. Asamura was first assigned to our firm’s Chemical Patent Department, where he handled chemical-related domestic and overseas patent applications (including foods, polymers, synthetic fibers, pharmaceuticals, and biotechnology). Later, when Japan adopted the new law school system, he joined Waseda Law School, and became a lawyer by successfully passing the bar examination and then completing his legal apprenticeship at Kagoshima District Court. After registering as a lawyer, Mr. Asamura worked as an associate for two years at Nagashima & Hashimoto, where he focused on foreign and domestic patent disputes and other related legal work.
In 2011, he returned to Asamura Patent Office, p.c. and established Asamura Law Offices, which is linked with the main firm.
Besides the management of Asamura Patent Office, p.c., as a patent attorney and lawyer, Mr. Asamura is currently teamed up with patent attorneys working at Asamura Patent Office in a wide range of areas. These include consultations about disputes related to patents, trademarks, designs, and copyrights as well as the Unfair Competition Prevention Act and similar areas, inter-party trials (invalidation trials and trials for cancellation), litigation rescinding trial decisions (ex parte, inter partes), warning letter correspondence, negotiations, cross-border injunctions, and litigation.
Mr. Asamura studied a wide range of materials at the Department of Materials Science in Chiba University’s Faculty of Engineering, from organic materials and high-polymer materials to inorganic materials. He also researched macrocyclic compound synthesis in the university laboratory.
As a master’s degree student at the University of Edinburgh, he researched a method for quantitative analyzing iron components in soil. Then at Lancaster University, he researched a method for analyzing compositional changes in fumaric acid and fulvic acid by soil depth.
Mr. Asamura has served as a member of the Japan Patent Attorneys Association’s Amicus Brief Committee (2011-2013), and as a member of the Association’s Intellectual Property Litigation Committee (2013 – 2014) where he was involved in examining court cases as well as the Japanese litigation system as related to intellectual property.
