Tradeshows are an incredible opportunity for innovators to showcase their latest products, attract potential investors, and network with industry leaders. However, one critical mistake can jeopardize your ability to secure a patent—publicly disclosing your invention before filing a patent application.
This mistake is more common than you might think, and it can have serious consequences. If you present, sell, or even discuss the details of your invention at a tradeshow without first filing for a patent, you may lose your ability to obtain one due to novelty requirements.
Why Public Disclosure Can Make You Lose a Patent
Patent laws around the world are designed to reward novelty. This means that for an invention to be patentable, it must be new and unpublished before the filing date. When you publicly showcase your invention—whether through a tradeshow, an investor pitch, or even a social media post—you create a public disclosure that can be used as prior art against your own patent application.
In many countries, such as Europe, China, and Japan, public disclosure before filing a patent results in an immediate loss of patent rights. The United States and some other countries offer a small grace period of 12 months, allowing inventors to file a patent after public disclosure, but relying on this grace period is risky. Competitors could file their own applications based on your idea, or you may face challenges during patent prosecution.
How to Avoid This Mistake
To ensure that your innovation remains protected, take these three key steps before heading to a tradeshow:
1. File a Patent Application Before the Event
The safest way to protect your invention is to file a patent application before showcasing it publicly. If your invention is still in development, consider filing a provisional patent application first.
Provisional Patent: A cost-effective way to secure an early filing date while giving you 12 months to refine your invention and file a non-provisional application.
Non-Provisional Patent: If your invention is ready and fully developed, filing a complete (or non-provisional) patent application ensures stronger protection and prevents competitors from capitalizing on your idea.
2. Use NDAs for Private Conversations
If you plan to discuss your invention with investors, manufacturers, or potential business partners, ensure that they sign a Non-Disclosure Agreement (NDA).
Why?An NDA legally binds them to confidentiality, preventing them from using or sharing your invention without your permission.
Tip: Not all investors or companies agree to NDAs, so be mindful of what details you share.
3. Be Strategic About What You Disclose
Even if you have filed for a patent, be mindful of what you present at a tradeshow. Competitors may still attempt to design around your invention or file competing patents.
Share only what is necessary—highlight key benefits rather than the technical details.
Avoid publishing your invention online until you have filed a patent.
Final Thoughts
A successful tradeshow can be a turning point for your innovation, attracting potential partners and customers. But failing to protect your intellectual property before showcasing it can lead to devastating consequences, including losing your ability to patent your invention.
By filing a patent before the event, using NDAs for sensitive discussions, and carefully managing what you disclose, you can confidently present your innovation without fear of losing your rights.
