Patent Sin #1. Oversharing: The Self-Inflicted Wound from Sharing Your Invention Before Filing

The Horror: Losing International Rights on Day One and US Rights in a Year

Inventors love to talk about their creations. They’re excited about them and want validation, investor feedback, and early market buzz. But the very first time you disclose your invention publicly, whether it’s on a social media post, a trade show demonstration, a sales pitch, or a tech journal, you start the clock ticking on your patent rights.

  • The US Deadline: In the U.S., you have a one-year grace period from the earliest public disclosure to file a patent application. File that application 12 months and 1 day after your first public disclosure, and NO PATENT FOR YOU!
  • The Global Nightmare: In some foreign countries, there is no grace period of any kind. Any public disclosure before filing a patent application can cause you to lose your rights in valuable markets across the globe. In many other countries, that deadline is just six months.

Actionable Takeaways

  • For US rights file your non-provisional patent application (or at least a detailed provisional) before you publicly use, sell, or disclose your invention. Then if you filed a provisional application, don’t forget to file the nonprovisional application within 12 months of the provisional filing date!
  • For foreign rights, check the grace periods and file your international application(s) before they expire. That may mean filing before any public disclosure!

Patent Pending Isn't Protection
Patent Pending Doesn’t Mean What You Think It Means

There’s a phrase that feels like it has magical powers in the patent world: patent pending. Most inventors think it means they’re protected while they develop, test, pitch investors, and bring a product to market. That’s not quite what it means, and the gap between those two ideas can cost
