An Innovation Cafe® article by Gary Shuster, patent litigator and prolific inventor.
This article rides with you on the journey from ideas to innovations and beyond. Today, we’re tackling a pretty common question: how do I patent an idea? More importantly, how do I patent an idea the right way?
Can you patent an idea?
The short answer: no, you can’t patent an idea. It’s that important. But don’t be discouraged.
An idea, by itself, isn’t patentable. It’s too abstract and conceptual. More importantly, it doesn’t do anything. An idea is ephemeral. It is not uncommon to confuse ideas with inventions, but they are different things. The idea is “I might be able to solve X by doing something with Y or Z” (or even more commonly, “it would be cool to solve X”). An invention is “doing Y in the following way, with or without Z, solves X.” Patents require something actionable, concrete, and sufficiently described—an invention.
But don’t get discouraged. Ideas are the seeds you use to grow inventions. Your idea can become a patentable invention. Here’s how to make that happen.
Turning an idea into a patentable invention
Develop solutions. Start with your idea—“wouldn’t it be cool if…?”—and think of concrete ways to solve the problem your idea addresses.
Reduce the invention to practice (this is required to get a patent). Physical reduction to practice means you build a working prototype. Constructive reduction to practice means you describe your invention in such detail—in a patent application—that someone skilled in the field (what patent law calls a “person having ordinary skill in the art”) could recreate it.
Ensure enablement. Your patent application must teach others how to build and use your invention. Include diagrams, flowcharts, and details a person having ordinary skill in the art would need to build the invention. Be careful not to leave things out. It is a common mistake for people who know a lot about a subject to assume that “everybody would know to do X first,” but that is not always true. If there is any question, err on the side of disclosing too much.
Avoid limiting language. Don’t box in your invention unnecessarily. For example, avoid language like “this invention must use argon gas only.” Something along the lines of “this invention uses any non-oxygenated gas, including heavy noble gases such as argon, and light ones such as helium” leaves more room.
Consider future applications. Your invention should solve problems in the near future—and remain useful for the life of the patent, if possible. A utility patent lasts 20 years from the date you file your application (with exceptions, such as a patent term adjustment, for U.S. patents). Anticipate technological progress and incorporate variations into your application, particularly where the technology can go in multiple directions in the near future. It is easy to invent for today, since you already know the dimensions of current knowledge and technology, and it is still relatively easy to predict where technology will go in a few years. Fifteen years out is quite difficult to predict. If you anticipate many of the directions a technology area may take going forward, you can invent for future developments, including variations using components that others are still creating.
The role of patent lawyers and patent agents
Patent lawyers can help you write a strong application, deal with legal issues, and provide attorney-client privileged advice and feedback. Finding the right patent lawyer is key—it’s a long-term relationship, so choose someone you can work with effectively. The best patent lawyers understand what you mean even if you’re unclear.
Patent agents are licensed by the USPTO but aren’t lawyers. They can help you with patent applications, but your discussions with them are not covered by the attorney-client privilege. While patent agents are often more affordable, you’ll need to consider this tradeoff carefully.
Steps to file a patent
Choose the right patent type. A provisional patent application gives you “patent pending” status for one year and lets you keep working on your invention before filing a full utility patent—and you can file multiple provisional applications over the course of that year as the invention develops, then roll them into a single utility application before the first provisional’s one-year anniversary. A utility patent application covers functional inventions and lasts up to 20 years. A design patent application protects ornamental designs.
Write a detailed disclosure. Work with your patent lawyer to write a disclosure that describes every aspect of your invention, including other implementations and applications.
File your application. Be careful about deadlines. Missing a filing deadline means losing your chance to protect your invention—of particular concern is filing less than a year after the invention becomes available to the public (the “on sale bar,” or otherwise, such as showing it to a person not under NDA), and filing before a competitor does. Even if you invent first, if a second person to invent files for a patent first, they will get the patent, not you.
Respond to office actions. Most patents are rejected a couple of times. Be prepared to work with your patent professional to address examiner suggestions and concerns and refine your application.
Example: from idea to invention
Let’s use a real-world example. The idea: preventing the re-upload of illegal files on a web hosting platform. The invention: techniques for fingerprinting files, identifying obfuscated or concealed content, and detecting files even when they’ve been altered or embedded. The patent: after developing practical methods and writing code to implement them, a patent was filed and issued.
Tips for inventors
Understand the problem. The best inventions solve well-defined problems. Spend time identifying and understanding the issue your idea addresses. A lot of the time, it requires more creativity to recognize the problem than to solve it.
Look for analogous solutions. Explore how similar problems in other fields have been solved—it can generate new ideas for your invention.
Collaborate carefully. If you need help developing your invention, ensure collaborators sign a non-disclosure agreement and assign patent rights to you. Patent assignments require special handling, so it is worth setting this up with an IP lawyer from the start.
Think visually. Use diagrams, flowcharts, or sketches to consolidate and build on your thoughts and communicate your invention clearly.
After the patent is issued
Remember, a patent is not a business plan. It doesn’t come with a check or a roadmap for monetization. Once your patent is granted, you are at the start of your trip, not the end. You need to decide whether to license, sell, or build a business around your invention. You should be prepared to enforce your patent rights if necessary. And it is smart to work with an experienced IP lawyer, IP broker, or inventor (or all three).
Final thoughts
Turning an idea into a patentable invention isn’t just about creativity—it’s about strategy, persistence, and preparation. With the right attitude and the help of a skilled patent professional, your idea can become a valuable piece of intellectual property.
