Strong networking with foreign associates

  • Mutual visits across borders

    We are interacting with our associates (patent lawyers and defense lawyers) from different countries, visiting each other's offices. This allows us to collect and accumulate the latest IP information from abroad. Building a trusting relationship with the foreign associates allows us to flexibly and smoothly handle cases in various situations.

  • Participation in international conventions

    We regularly attend various international conventions -- including those held by International Trademark Association (INTA), Asian Patent Attorneys Association (APAA), International Association for the Protection of Intellectual Property (AIPPI), International Federation of Intellectual Property Attorneys (FICPI), American Intellectual Property Law Association (AIPLA), and European association representing the interests of brand owners (MARQUES). Participaing in these meetings strengthens our existing networks and helps us bulid new networks with foreign law firms.
