What does an intellectual property lawyer in Japan do?
An intellectual property lawyer protects and enforces trade marks, patents, copyright, designs and confidential information, and handles licensing and infringement disputes. You are likely to need one when you launch a brand or product, license technology, enter a new market or suspect someone is copying your work.
How do I find a good intellectual property lawyer in Japan?
Check that they are qualified or registered to practise in Japan, for example with the local bar association or professional body, and that they have handled matters like yours, including any cross-border element. Ask who will do the work, which languages they work in and how they charge before you instruct them. Each intellectual property lawyer listed on this page has a profile with their firm, practice areas and contact details, so you can compare them before getting in touch.
How much does an intellectual property lawyer in Japan cost?
Fees depend on the firm, the experience of the person advising you and how complex the matter is. Firms commonly charge by the hour, a fixed fee for a defined piece of work, or a combination of the two. Ask for a written estimate and the terms of engagement before any work starts.
Do I need a local intellectual property lawyer in Japan if I am based abroad?
Matters governed by the law of Japan, or that involve its courts, registries or authorities, usually need an adviser qualified there. If you already have an adviser at home, they can often work alongside a local intellectual property lawyer in Japan, which keeps the advice joined up on cross-border matters.
Can I find an English-speaking intellectual property lawyer in Japan?
Many lawyers and advisers who work with international clients advise in English, but it is worth checking. Ask about working languages when you first get in touch, and whether documents can be provided in English as well as the local language.
