Many independent inventors believe an invention must be completely different from anything that came before it in order to qualify for patent protection. That is not how the patent system works. Many patents protect improvements to existing products, systems, and methods. In fact, much of American innovation occurs through refinement rather than complete reinvention. Inventors improve existing technology every day. … Read More

Gerhard Fischer Metalloscope

One of the most common questions inventors ask is whether they can patent an idea. The answer is usually no. Every invention starts with an idea, but the patent system protects inventions, not ideas. That distinction is important. Many people use the terms “idea” and “invention” interchangeably. Patent law does not. An idea is often the beginning of the inventive … Read More

Faloon Metallic and Barbed Wire Fence

If you have ever read a patent, you probably noticed that claims came across as awkward, repetitive, and unnatural. Words repeat. Sentences run long. The structure feels rigid. Your high school English teacher would probably wonder how a patent practitioner ever got into college. But patent claims are not the result of bad grammar or poor prose. They do not … Read More

Thomas Edison Phonograph or Talking Machine - Patented 1916

Inventors tend to focus on describing how their invention works. They explain the components, the structure, and the intended use. That is necessary, but it is not enough. Most inventors have never heard the phrase “secondary considerations,” and even those who have tend to underestimate it. The term sounds like an afterthought, something optional or minor, but in patent law … Read More

Many inventors assume that once a patent application is filed with the United States Patent and Trademark Office (USPTO), the next step is simply waiting for the patent to issue. In reality, the process rarely works that way. Most patent applications enter a stage known as patent prosecution. After filing, a USPTO patent examiner reviews the application and determines whether … Read More

Scott ThorntonInventor Help, Patent Law

A classic clock mechanism from the early 20th century

The United States patent system follows a first-to-file rule. This means the inventor who files a patent application first usually secures the earliest priority date for an invention. If two people independently create similar technology, the inventor who files first generally has the stronger legal position. For inventors, this creates an important lesson. Timing matters. Waiting too long to file … Read More
