A patent is a special rule. 
A patent is a special rule for new ideas. 

A patent is a special legal right. It belongs to people who make new things. This right lets an inventor stop others from using their idea. They can stop others from making or selling it. In return, the inventor must share how the invention works.
This system is very old. One of the first laws was in Venice in 1474. That law protected new tools for ten years. Later, England made rules to help new inventions grow. In 1790, the United States passed its first patent law. The first U.S. patent went to Samuel Hopkins. He found a way to make potash.
In the past, it was hard for women to get patents. In the U.S., married women could not own property. This meant they could not own their inventions. Today, things are changing. In 2023, about 17.7% of inventors were women. More women are now sharing their new ideas with the world.
A patent is a special type of legal right for inventors. It is a part of what people call intellectual property. This right does not actually give someone the power to make a product. Instead, it gives them the power to stop others from making or selling it. In exchange for this protection, the inventor must publish a full description of how the invention works. This way, the public can learn from the new idea. Most patent protections last for at least twenty years. This helps inventors benefit from their hard work for a limited time.
To get a patent, an inventor must follow a specific process. They must submit an application that includes one or more claims. These claims define exactly what the inventor wants to protect. For an invention to qualify, it must be new and useful. It also must involve an inventive step and be capable of industrial use.
History shows us that these rules have changed a lot over time. The word patent comes from the Latin word patere, which means "to lay open." This refers to making an invention available for everyone to see. One of the first official systems was the Venetian Patent Statute in 1474. In Venice, new devices were protected for ten years. Later, the English system helped the Industrial Revolution grow. In 1624, the Statute of Monopolies limited the King's power to grant rights. This ensured that patents were only for truly new inventions. This legal foundation helped many countries build their own systems.
Many important milestones happened as patent laws grew. In 1641, Samuel Winslow received the first patent in North America for making salt. The United States passed its first Patent Act on April 10, 1790. On July 31, 1790, Samuel Hopkins of Vermont received the first U.S. patent. He invented a way to produce potash. By the time of the American Civil War, about 80,000 patents had been granted in the U.S. In the 1790s, legal battles over James Watt's steam engine helped define how patents work. These cases showed that you could patent improvements to old machines.
Not everyone had the same chance to be an inventor in the past. For a long time, there was a large gap between men and women in patents. In the U.S., married women often could not own property or income. This made it very hard for them to hold patent rights. However, things are changing as more women enter science and technology. In 2023, women made up 17.7% of inventors in certain global applications. Today, patenting is a huge part of how the world shares new technology. From software to biology, patents help connect new ideas to the people who use them.
A patent is a specific type of intellectual property. Intellectual property refers to creations of the mind. A patent gives an owner the legal right to exclude others. This means they can stop others from making, using, or selling their invention. This right lasts for a limited period of time. In exchange, the inventor must provide an enabling disclosure. This is a detailed explanation of how the invention works. This disclosure makes the knowledge available for public inspection. 
It is important to understand what a patent does not do. A patent is not a direct grant to make or sell a product. Instead, it is the right to exclude others from doing so. An inventor might still need a license from someone else to practice their invention. This happens if their new idea relies on an older, more basic patent. To get protection, an inventor must file a patent application. This application includes one or more claims. These claims define the specific scope of the protection being sought.
Different types of patents exist depending on the jurisdiction. In the United States, industrial design rights are called design patents. Plant breeders' rights are sometimes called plant patents. Some countries also use utility models. These are often called petty patents or innovation patents. They usually have a shorter monopoly period than standard patents. There are also specific categories for different fields. These include biological patents, chemical patents, and software patents. The term utility patent is often used to distinguish primary inventions from these other types.
The history of patents stretches back many centuries. The word comes from the Latin "patere," meaning "to lay open." This refers to the practice of making information public. One of the first statutory systems was the Venetian Patent Statute of 1474. In Venice, new devices were protected for ten years. Recent research suggests this may have been inspired by laws in the Kingdom of Jerusalem. The English system later became a foundation for modern law. In 1624, the Statute of Monopolies restricted the King's power. This ensured patents were only for original inventions. 
Many significant milestones shaped modern patent law. In 1641, Samuel Winslow received the first North American patent. It was for a process to make salt. The United States passed its first Patent Act on April 10, 1790. Samuel Hopkins received the first U.S. patent on July 31, 1790. He invented a method for producing potash. By the time of the American Civil War, about 80,000 patents had been granted in the U.S. In the late 1700s, James Watt fought legal battles over his steam engine. These cases proved that improvements to existing machines could be patented. 
Historically, there has been a significant gender gap in patenting. In the United States, married women were often unable to own property. This meant they could not legally own the income from their inventions. In the United Kingdom, only 8% of inventors were female in 2015. However, this gap is slowly closing. In 2023, women accounted for 17.7% of inventors in certain global applications. This change is linked to more women entering STEM fields. STEM stands for science, technology, engineering, and mathematics. 
Global patent activity shows interesting patterns over time. The United States led the world in patent families from 1900 to 1966. Japan took over this leadership after 1966. Since 2007, China has led the world in patent filings.
