The moment you start selling your invention is the moment you might be ending your right to protect it.
Kurt Jones invented Dippin' Dots and validated the idea the obvious way — he sold them at state fairs for a year. That year triggered what patent law calls the on-sale bar. When competitors entered, his patent was ruled unenforceable. The product survived because the brand survived. The legal protection he thought he had? Gone before the competitors showed up.
Intellectual property law exists because the U.S. government made a deal with inventors: tell us how it works, and we'll give you twenty years to own it. The catch is you have to tell the government before you tell everyone else.
Ideas Are Worth Nothing; Execution Is Worth Everything
Three founders with the same idea produce three different companies for three different markets. The idea itself doesn't carry value — execution does. This matters because founders waste enormous energy trying to protect the wrong thing.
Asking an investor to sign an NDA before your pitch signals you don't understand this yet. No real investor will sign one. They see hundreds of ideas; yours isn't special enough to steal, and even if it were, execution is what builds a company. If your execution is better, the idea doesn't matter. If theirs is better, the NDA wouldn't have helped anyway.
File a Provisional. It's Cheap. It Matters.
If you've built something genuinely new and believe it might be patentable, file a provisional patent before you sell it publicly. A provisional costs roughly $1,500 with an attorney, less if you write it yourself. It doesn't grant protection — it establishes your date.
The U.S. switched to a first-to-file system in 2013. Whoever files first wins. The date on your provisional is the competitive moat, not the patent document itself. File it before you pitch. File it before you post. File it before you sell anything publicly. You have a one-year grace period domestically before public sales kill your rights. Internationally, that window is zero.
What Each Type of Protection Actually Does
Patents protect how an invention works. Trademarks protect your name from being copied. Copyrights protect original creative content, including code. Trade secrets protect confidential information indefinitely, as long as you actually keep it secret — Coca-Cola's recipe has never been patented, requiring NDAs from anyone who touches the process.
Software sits awkwardly across all four categories, and AI makes it murkier. If AI helped you build something, your ability to patent, copyright, or trademark it is genuinely unclear. The law hasn't caught up.
Patents Deter; They Don't Stop
A patent without the money to enforce it is theater. Patent litigation costs $100,000 to $200,000 before anyone wins. Early-stage startups can't afford that fight, and competitors know it. The real value is signal — it tells potential infringers the legal cost of copying you might exceed the reward.
Build a business worth protecting first. Once you're generating real revenue, clean up the IP with proper filings. File your provisional early to lock in the date, add continuation patents as the product evolves, and save the expensive legal work for when you can afford it and when there's something real to protect.
