What does an intellectual property lawyer do?
Intellectual property law protects creations of the mind: patents, trademarks, copyright, designs, trade secrets and related rights. Lawyers clear and register rights, draft licences and assignments, and enforce or defend against infringement. Most rights are territorial, so protection is usually needed country by country.
How do I choose an intellectual property lawyer in Tokyo Prefecture?
- Ask whether the lawyer or firm can file in the countries where you trade, directly or through a network of agents.
- For patents, check for technical qualifications in your field; in some countries patent attorneys are a separate regulated profession.
- Bring examples of your brand or invention, dates of first use and any earlier filings.
- Confirm the lawyer is admitted and in good standing with the bar or law society in Japan, and ask who will handle your matter.
