Mycat Co., Ltd. (Headquarters: Meguro-ku, Tokyo) has newly released a tool on its AI trademark search service "Trademark Navi" (https://shohyo.xyz) that allows users to pre-check the trademark risk of service and brand names.

Tool URL: https://shohyo.xyz/tools/risk-check

Tool Overview

The trademark risk pre-check tool is a function that, when a candidate service or brand name is entered, the AI cross-references it with the Japan Patent Office's trademark database and displays a score indicating the similarity to existing trademarks.

Items that can be checked

Similarity score with existing trademarks (0-100)
List of similar existing trademarks
Recommendation of trademark classes (45 classes) for application
3-stage evaluation of refusal risk (low, medium, high)

Development Background

According to the Japan Patent Office's "Annual Report on Patent Administration," the number of trademark applications annually totals approximately 158,000, of which about 20% receive a refusal (Source: Japan Patent Office 2023 Annual Report on Patent Administration). The main reasons for refusal are "similarity to existing trademarks" and "lack of distinctiveness."

There have been cases where startup companies are forced to change their service names after discovering similarities to existing trademarks after launching their business. The cost of rebranding significantly exceeds the cost of prior trademark research, making pre-launch checks crucial.

How to Use: Assess Risk in 3 Steps

1. Enter the service or brand name you want to check

2. Select the business field (industry)

3. AI instantly displays the similarity score and refusal risk assessment

Trademark Risks Startups Often Face

Cases where an existing trademark is discovered after service launch, requiring a name change
Cases where common words are adopted as service names and rejected due to lack of distinctiveness
Cases where the selection of trademark classes for application is incorrect, resulting in insufficient scope of protection

By utilizing this tool, these risks can be identified before launch.
