[July 30, 2026]An original script was created based on actual trademark lawsuits in Japan involving Zoom, a Japanese audio equipment company, and Zoom, a U.S. video conferencing company. At the time the script was prepared based on several broadcasts, the written judgment in the trademark infringement lawsuit had not yet been published on the court’s website.

### Cast of Characters

- **Attorney Soma** — Plaintiff's counsel. Female. Cool-headed and razor-sharp.

- **President Sumita** — President of Zoom Corporation. Male. Outwardly calm, inwardly passionate.

- **Roberto Matsumoto** — Head of Legal & IP at Zoom Video Communications. Second-generation Japanese-American. Male. Speaks casually and directly, with a laid-back American flair, due to years spent in Japan as a child.

- **Ono** — Legal counsel at the Japan subsidiary. Male. Timid and anxious.

- **Judge** — Female. Elderly. Gentle, but piercing.

## Scene 1 — Soma's Narration

**Attorney Soma:**

I'm a lawyer who specializes in corporate law. Lately, most of my work involves intellectual property — trademarks, copyright, that sort of thing.

In Japan, many people feel a certain resistance to filing a lawsuit.

*"I don't want this to become a legal matter."*

*"I'd rather settle things quietly."*

I understand that instinct perfectly.

But litigation is one of the tools available when a dispute between parties has reached a dead end — a way to move things forward, toward resolution. When it's necessary to protect your interests, it should be used.

The client who came to my office this time was the president of Zoom Corporation, a manufacturer of audio equipment.

## Scene 2 — The First Consultation

**President Sumita:**

Attorney Soma, thank you for seeing me today.

**Attorney Soma:**

I've reviewed the materials.

This concerns Zoom Video Communications, correct?

**President Sumita:**

Yes. We've been receiving inquiries about the video conferencing Zoom.

Things like — "I can't join a meeting" or "I want to cancel my account."

**Attorney Soma:**

Inquiries that have nothing to do with your company.

**President Sumita:**

Exactly. We're an audio equipment manufacturer.

Recorders, microphones, headphones — we work with sound.

**Attorney Soma:**

Your company was founded in 1983?

**President Sumita:**

That's right.

We're not a flashy company, but we've worked steadily, day after day.

We've spared no effort when it comes to sound quality.

As a result, our products have earned a strong reputation among audio professionals — radio broadcasters, musicians, and the like.

**Attorney Soma:**

Do your products carry the Zoom name?

**President Sumita:**

Yes. The logo appears on both the products and the packaging.

So honestly — having someone else use the same name is a real problem for us.

But they're a global service.

Will they even take us seriously?
