Key Takeaways

  • A patent grants inventors exclusive rights to their creations, protecting them from unauthorized use or sale.
  • There are different types of patents—utility, design, and plant—each covering unique aspects of innovation.
  • The U.S. Patent and Trademark Office (USPTO) processes hundreds of thousands of applications annually, with technology and pharmaceutical sectors leading in patent volume.
  • Historical patents, such as those for the light bulb and telephone, illustrate the transformative role of patents in human progress.
  • International patent protection is governed by treaties such as the Patent Cooperation Treaty (PCT).
  • Patent litigation, a critical part of enforcement, ensures inventors can defend their rights against infringement.
  • Patents have expiration timelines—typically 20 years for utility patents—with required maintenance fees to remain active.

What Are Interesting Facts About Patents?

Interesting facts about patents abound but while many people are familiar with the term, they do not know what a patent is and why someone needs it. Interesting facts cover a variety of issues such as why you should hire a patent attorney and when a patent expires. 

Types of Patents and What They Protect

Patents fall into three main categories: utility, design, and plant patents.

  • Utility patents protect new and useful processes, machines, or compositions of matter, covering most modern inventions, from software to pharmaceuticals.
  • Design patents safeguard the unique appearance or ornamental design of a functional item, such as a smartphone’s shape or a sneaker’s sole.
  • Plant patents apply to new and distinct varieties of plants reproduced asexually, protecting agricultural innovation.

Understanding these distinctions helps inventors choose the right protection for their creations and avoid overlap with trademarks or copyrights.

Pros of Patents

Among the interesting patent facts throughout history, it is clear there are pros and cons when considering a patent for your invention. 

  • A patent protects the inventor's rights to the invention preventing anyone else from patenting the same invention.
  • Patents are easily searched online free of charge.
  • Hiring a patent attorney assures you that the person has significant knowledge, experience, and an undergraduate degree in a selected field of science. 
  • As global competition in the marketplace increases worldwide, the U.S. has ranked high in the number of patents granted annually. 
  • A study by Brookings noted a patent can average $500,000, or more, for large companies and an estimated $1 million for lesser known companies. 

Cons of Patents

  • Although searching for the availability of a patent for an invention is easy to do, there is no guarantee it will be available when you decide to apply. This is due to a lengthy wait for application approval. 
  • An application for a patent can be in pending status for approximately three years. 
  • Sending a letter of intent to the patent office to alert the office of the invention to protect it has no effect. A letter will not protect an invention from being patented by someone else. 
  • A patent is no guarantee an invention is viable or valuable.
  • Similar names can be a reason to reject a patent application. For example, the phrase "Eat More Kale" was denied by the patent office because of its similarity to "Eat More Chickin" which is a nationwide phrase used in marketing by Chick-Fil-A.

Global Patent Protection and the PCT System

Inventors seeking global protection often use the Patent Cooperation Treaty (PCT), which streamlines the international patent filing process. Rather than filing separate applications in each country, inventors can file one PCT application, which reserves their priority rights in over 150 participating nations.However, the PCT does not grant a global patent; applicants must still pursue patents individually in each country after the initial international phase.

This system makes it easier for inventors to explore international markets, secure investors, and protect intellectual property globally. Understanding patent jurisdiction and regional rules—such as those governed by the European Patent Office (EPO) or Japan Patent Office (JPO)—is crucial for inventors expanding internationally.

Historical Patent Facts and Famous Inventions

The history of patents is filled with remarkable examples of human ingenuity. The first U.S. patent was granted in 1790 for potash production, marking the start of formalized intellectual property protection.Some iconic patents include:

  • Thomas Edison’s light bulb (U.S. Patent No. 223,898, 1880), which revolutionized modern life.
  • Alexander Graham Bell’s telephone patent (1876), leading to global communication networks.
  • The Wright brothers’ airplane patent (1906), paving the way for aviation.

Today, patent filings continue to grow worldwide. The U.S., China, Japan, South Korea, and Germany consistently rank among the top five nations for annual patent applications. The growing focus on AI, biotechnology, and renewable energy has made these fields particularly patent-heavy.

Deadline for Patents

Once filed, a patent is valid for 20 years. 

Throughout the term of the patent at pre-determined intervals, the applicant is responsible for paying maintenance fees to keep the patent active. If not paid, is patent is deemed abandoned. 

Surprising Modern Patent Facts

Modern patent trends reveal fascinating insights:

  • Technology companies dominate: IBM, Samsung, and Canon have historically ranked as the top patent holders globally, filing thousands annually.
  • Artificial Intelligence (AI) is one of the fastest-growing patent categories, covering everything from self-driving algorithms to generative AI systems.
  • Women inventors represent a growing share of patent holders, with initiatives by the USPTO and WIPO aimed at improving gender diversity in innovation.
  • Expired patents fuel innovation by entering the public domain, allowing startups and small businesses to build upon older technologies.

These patent facts highlight how innovation and legal protection intersect to shape technology, business, and society.

Patent Enforcement and Litigation

Even with a valid patent, enforcing rights requires vigilance. Patent litigation occurs when an inventor or company sues another for infringing on their patent rights. These disputes are handled in federal courts and often involve complex legal and technical evidence.

Common forms of patent litigation include:

  • Infringement suits, when a party uses a patented invention without permission.
  • Declaratory judgments, where a company seeks confirmation that its product does not infringe an existing patent.
  • Inter partes reviews (IPRs), administrative challenges at the U.S. Patent and Trademark Office (USPTO) to test a patent’s validity.

Patent litigation can be costly and time-consuming, but it plays a crucial role in ensuring inventors’ rights are respected and innovation remains incentivized.

Frequently Asked Questions

  1. How long does a patent last?
    Most utility patents last 20 years from the filing date, while design patents typically last 15 years. Maintenance fees are required to keep patents active.
  2. Can I file a single patent that covers all countries?
    No. There is no global patent, but you can file under the PCT to reserve rights in multiple countries.
  3. What happens if I don’t pay maintenance fees?
    If maintenance fees aren’t paid, the patent is considered abandoned, and others may use the invention.
  4. How do patents differ from trademarks and copyrights?
    Patents protect inventions and functional designs, trademarks protect brands and logos, and copyrights protect creative works like literature and art.
  5. Can a patent be challenged after it’s granted?
    Yes. Third parties can file challenges, such as post-grant reviews or inter partes reviews, to question a patent’s validity at the USPTO.
