🎙 Hosted by Adam Diament, Registered Patent Attorney | Partner, Nolan Heimann LLP
Sharing a patent may sound like a good idea—until your co-owner licenses it to your competitor and leaves you powerless.
In this episode, Adam Diament breaks down the risks of joint patent ownership and why it often ends in regret. From real-world case law to investor red flags, you’ll learn how this common IP mistake can sabotage your rights—and how to avoid it.
🧠 What you’ll learn:
- What joint ownership of a patent legally means
- Why your co-owner can license or sell without you
- A cautionary tale: Schering v. Roussel
- What happens when your co-owner sells to someone you don’t know
- How to fix or avoid the mess: assignment tips, joint ownership agreements, and neutral entities
📌 Bottom line: joint ownership without a written agreement is not a team sport—it’s a liability.
