Best IP Licensing & Transactions Lawyers in Yokohama, Kanagawa

When a Yokohama business should get legal advice on an IP deal

Intellectual property licensing and transfer work in Yokohama commonly involves patents, trademarks, software, designs, copyright, and confidential know-how. Businesses may need advice when licensing technology to a supplier, commercialising research, using another company’s brand, or transferring IP as part of a business sale.

Japan’s national laws govern IP rights and registrations; Yokohama does not have a separate city licensing regime. For a Yokohama company dealing with overseas customers or suppliers, the agreement should also address governing law, language, currency, territory, and how rights will be enforced across borders.

Terms such as “exclusive” and “non-exclusive” have practical consequences, and registration requirements vary by right. A lawyer can check whether the contract matches the parties’ commercial intentions and coordinate with a Japanese patent attorney when registration or technical IP work is needed.

Why you may need a lawyer

• A Yokohama manufacturer is licensing a patented process or tooling to a domestic or overseas supplier and needs to define permitted products, territory, quality controls, and sublicensing.
• A company is negotiating an exclusive trademark licence for products sold through Yokohama’s port and other distribution channels, and needs to protect brand standards and control the licensee’s use.
• A software or technology business is granting access to code or know-how and needs clear limits on copying, modification, security, support, and use of confidential information.
• A business is commissioning product design, software, or research and needs to establish who owns the resulting IP and whether either party can reuse it.
• A university-linked venture or research partner is commercialising jointly developed technology and needs to divide ownership, patent costs, licensing income, and publication rights.
• A company is buying, selling, or restructuring a business and needs to verify that registered rights, employee-created work, and existing licences can be transferred as planned.

Local laws that shape IP agreements

Patent Act: This law governs patent rights and patent licences. An exclusive licence requires registration to take effect; since amendments effective 1 April 2012, a qualifying non-exclusive licence can generally be asserted against a later patent owner without registration.

Trademark Act: This law governs trademark rights and licences. The type of licence, its terms, and any required registration should be checked before relying on a licensee’s ability to use or enforce rights against others.

Copyright Act: This law governs copyright in works such as software, designs, and written material. Under Article 61(2), a transfer agreement does not presume that rights under Articles 27 and 28 have transferred unless it expressly says so.

Frequently asked questions

What does intellectual property licensing and transfer work cover?

It covers agreements that permit another party to use IP, as well as assignments that transfer ownership. The work may also include development, confidentiality, co-ownership, and royalty arrangements.

Do I need a lawyer to prepare an IP licence?

Legal advice is especially useful when the deal involves exclusivity, substantial royalties, foreign parties, sensitive know-how, or rights created through joint work. A lawyer can review the contract alongside any required registration steps.

Does an IP licence have to be registered in Japan?

Requirements depend on the right and the kind of licence. For example, a patent exclusive licence requires registration to take effect, while a qualifying non-exclusive patent licence generally has different rules.

Can a licence be valid without registration?

Some contractual permissions may operate between the parties without registration, but that does not mean they will have the same effect against later owners or third parties. The answer depends on the IP right and licence type.

How long does it take to negotiate a licence?

A straightforward agreement may take a few weeks once the parties agree on the main terms. Complex deals involving multiple rights, technical review, foreign parties, or registration can take longer.

What does a lawyer cost in Yokohama?

Fees vary with the lawyer, language needs, transaction value, and document complexity. Ask for a written estimate covering review or drafting, negotiation, registration coordination, translation, and any applicable consumption tax.

Can a foreign company license IP to a Yokohama business?

Yes, but the agreement should identify the rights, territory, permitted uses, governing law, payment method, and dispute process. Japanese registrations or filings may still be relevant when the rights concern Japan.

Who owns work created by a contractor or development partner?

Ownership depends on the relevant rights, the working relationship, and the contract; payment alone may not settle every ownership question. State expressly which rights transfer, which remain licensed, and what each party may reuse.

What should a university or research spinout address?

It should confirm who owns existing and newly developed IP, who pays for filings, and who may license or publish the results. The agreement should also set out revenue sharing and access to research materials or data.

Should I hire a lawyer or a patent attorney?

A bengoshi, or Japanese lawyer, can advise on contract terms and legal risks. A benrishi, or Japanese patent attorney, can assist with patent and other IP procedures; some transactions benefit from both professionals.

Can a small business or individual hire an IP lawyer?

Yes. There is no general requirement that a client be a large company, although the lawyer may ask about the rights, budget, and transaction scope before accepting the work.

What if the other party breaches the agreement?

Review the notice, cure, termination, payment, and dispute-resolution clauses before taking action. A lawyer can assess evidence and options, including negotiation or proceedings in the appropriate forum.
