# Unfair Competition Prevention Act Services

Professionals Protecting Brands, Technologies, and Trade Secrets from Unfair Practices

## Consultation Process

1

Initial Consultation (Free)

We will discuss cases involving suspected unfair competition or situations where you have received a warning. We can assist via phone, email, or online.

2

Legal Analysis and Strategy Development

We will analyze whether the case falls under the Unfair Competition Prevention Act and propose the optimal response strategy. We will also consider how to combine this with registered rights.

3

Drafting of Warning Letters and Negotiations

We draft cease-and-desist letters to infringers and aim for a resolution through negotiation. We also file infringement reports with e-commerce platforms.

4

Litigation Support (as needed)

If a resolution cannot be reached through negotiation, we will work with our affiliated attorneys to support litigation seeking injunctions and damages.

## Frequently Asked Questions

Q. Can I protect my brand even if I haven’t registered a trademark?

Yes. Under the Unfair Competition Prevention Act, your brand may be protected as a “well-known indication of goods, etc.” (Article 2, Paragraph 1, Item 1) even without trademark registration. However, since proof of widespread recognition is required, combining this with trademark registration provides more reliable protection.

Q. What is the protection period for exact copies (imitation of product design)?

It is three years from the date of first sale. Since protection under the Unfair Competition Prevention Act ends after three years, we recommend registering a design patent for long-term protection. A design patent provides protection for up to 25 years from the date of application.

Q. What are the requirements for protection as a trade secret?

Three requirements must be met: (1) **Secrecy management**: The information must be managed as a secret (e.g., access restrictions, confidentiality markings), (2) **Usefulness**: The information must be useful for business activities, and (3) **Non-publicity**: The information must not be publicly known. Proving secrecy management is often a point of contention, so establishing internal systems is crucial.

Q. How can I stop the sale of counterfeit goods on e-commerce sites?

Major e-commerce platforms such as Amazon, Rakuten, and Mercari have systems for reporting intellectual property infringement. If you allege infringement under the Unfair Competition Prevention Act, you can request the removal of listings or the suspension of accounts by submitting evidence of the counterfeit products to the platform.

Q. What are the benefits of hiring a patent attorney?

As intellectual property experts, patent attorneys can assess whether a case falls under the Unfair Competition Prevention Act, collect evidence, draft cease-and-desist letters, and file infringement reports with e-commerce platforms. Additionally, they can propose a mixed intellectual property strategy combining patents, trademarks, and designs, enabling the establishment of a more robust protection framework. If litigation becomes necessary, we collaborate with our partner attorneys.
