A Patent Grave Mistake: Public Disclosure

Publicly disclosing your invention before you file a patent application can be a grave mistake.

This is one of the most terrifying things an inventor can do. In the U.S., you can lose your right to patent your invention if you talk about it publicly more than one year before you file. In some countries, once it’s public, there’s a shorter grace period or no grace period at all.

Imagine showing off your prototype at a trade show to excited buyers. Then you get busy, and time flies past you. You keep meaning to file a patent application but also keep forgetting to take any steps toward actually doing that. Six months go by, and you’ve lost your ability to get patent protection in the UK and much of Europe. Then it’s 12 months, and you’ve lost your ability to get a patent in the US, Canada, and Mexico.

Don’t fall into this open grave! It’s best to keep your brilliant ideas secret until you’ve talked with a patent attorney about the timing of making things public and filing patent applications.

Intellectual property is one of the most terrifyingly useful tools you have. If you’re a creator or other entrepreneur ready to build a frighteningly powerful brand and business, you need to know how to use it. You don’t have to face the darkness alone, though.

I help entrepreneurs across the U.S. make smart, legally sound decisions about their intellectual property. I’m an attorney in Champaign-Urbana, Illinois, but I serve intellectual property clients nationwide.

Tales from the Crypt(ic Requirements): Trademark Specimens and Intent-to-Use Trademark Applications Decoded

Thinking about filing a trademark before you launch? Intent-to-Use applications and specimen requirements are more complex than they appear. Patent attorney Julie King explains what goes wrong and why trademark attorney guidance matters. You’ve got a great brand name. Maybe you’ve designed a logo. You’re getting ready to launch your business or product. But here’s the question everyone asks: Should you wait until you’re actually selling products to file for a trademark? Or can you file now and secure your rights before launch?

Trump trademarks and the Domestic Emoluments Clause

Current Events: Trump Trademarks and the Domestic Emoluments Clause

How Trump Business Ownership of Airport Trademarks Would Violate the Domestic Emoluments Clause: How does the Domestic Emoluments Clause apply to these trademark applications? Who names airports? That’s right, Congress does, for airports under federal jurisdiction, and the states do for state-owned airports.
Trump has asked for the Palm Beach International Airport and Dulles International Airport to be named after him. Given that these applications also cover airport construction, it’s not a leap to think there may be future airports Trump wants to be named “DONALD J. TRUMP INTERNATIONAL AIRPORT” and/or “PRESIDENT DONALD J. TRUMP INTERNATIONAL AIRPORT,” especially if the proposed renaming of the Palm Beach and Dulles airports doesn’t happen. Note that the trademarks for the Ronald Reagan Washington National Airport are owned by the public entity that runs the airport, Metropolitan Washington Airports Authority (DISTRICT OF COLUMBIA Federal Agency Assignee of United States (D.C. Body Politic and Corporate) ), NOT a private company.
