Notepad++ Creator Files Trademark Complaint Over Unofficial macOS App

Don Ho has filed a trademark complaint against an unauthorized macOS port of Notepad++, escalating a dispute over branding, user trust, and potential security risks.

Complaint Targets Misleading macOS Version

As reported by The Register, Ho sent a formal complaint to Cloudflare targeting a website distributing a macOS version of Notepad++. The project, created by developer Andrey Letov, used the Notepad++ name, logo, and even Ho’s biography, presenting itself as an official release.

While the site included a disclaimer, it appeared below the main content, making it easy for users to miss.

Trademark vs Open Source

The core of the issue lies in the difference between open-source licensing and trademark rights. Notepad++ is licensed under GPL v3, which allows developers to fork and modify the code.

However, the Notepad++ name and logo remain trademarked. Ho argues that reusing them without permission crosses a legal line and misleads users into trusting an unofficial product.

Security Concerns Raised

The situation also triggered warnings from contributors and the broader community. An unofficial app posing as legitimate software raises the risk of hidden vulnerabilities or even malware.

This concern carries extra weight after past incidents where compromised Notepad++ updates were used to spread malicious code. Any similar issue tied to a fake version could damage the project’s reputation.

Developer Response and Escalation

Letov initially hoped to gain Ho’s endorsement and even added a claim suggesting coordination with the original creator. Ho denied any involvement and demanded a full takedown.

The developer later asked for time to rebrand the project, but Ho rejected the request and continued to pursue removal.

Rebrand Attempt Fails to End Dispute

At the time of reporting, the site remains online but has been rebranded to “Nextpad++ for Mac,” featuring a different logo.

Despite the change, the dispute remains unresolved, and further legal action remains on the table.

The case highlights a recurring issue in open-source ecosystems: code can be reused, but branding cannot. It also reinforces the growing focus on software authenticity and supply chain security, especially after multiple high-profile incidents involving tampered updates.

With Notepad++ widely used across Windows systems, protecting its identity has become just as important as maintaining its codebase.
