Patents are legal instruments that grant exclusive rights to inventors and creators to prevent others from producing, using, or selling their innovations for a certain period of time. They incentivize innovation by allowing inventors to commercially exploit their creations. There are various types of patents, each serving a different purpose and providing different levels of protection. In this blog post, we'll explore the different types of patents, including utility patents, design patents, and plant patents, to help you understand the patent landscape and make informed decisions about protecting your own innovations.

Provisional Application
A provisional application is a type of patent application that serves as a placeholder for inventors. It allows inventors to secure an early filing date for their invention while they take additional time to refine the invention and prepare a non-provisional patent application.
Provisional applications are typically less expensive to file than non-provisional patent applications and they typically have a lower level of formality compared to non-provisional applications. Provisional applications generally do not undergo examination by the patent office, and they do not result in the grant of a patent unless the inventor files a corresponding non-provisional patent application within a specified time period.
Provisional applications can be a useful tool for inventors who are still in the early stages of developing their invention, as they allow the inventor to quickly secure an early filing date and begin the patenting process, without incurring the cost and effort of preparing a full, non-provisional patent application.
PCT - Patent Cooperation Treaty
The Patent Cooperation Treaty (PCT) is an international treaty that provides a unified and streamlined process for filing patent applications in multiple countries. The PCT system allows an inventor to file a single international patent application, which can then be processed by national and regional patent offices in the countries where the inventor wishes to seek patent protection.
A PCT patent refers to a patent that has been granted under the PCT system. This means that the inventor has filed an international patent application under the PCT, and that one or more national or regional patent offices have granted the inventor a patent for their invention. The PCT system provides a number of benefits to inventors, including the ability to file a single application in multiple countries, and to defer the cost and complexity of filing separate applications in each country.
Overall, the PCT system provides inventors with a convenient and efficient way to seek patent protection in multiple countries, without having to navigate the complex and often confusing landscape of national and regional patent laws and regulations.
Utility Patents
Utility patents are the most common type of patent and protect new and useful inventions or discoveries related to machines, processes, compositions of matter, or methods of doing business. These patents cover the functional aspects of a product or an invention and give the inventor exclusive rights to make, use, and sell the invention for 20 years from the date of filing the patent application.
Examples of inventions that can be protected by utility patents include new consumer products, software, medical devices, and even genetically engineered plants. To be eligible for a utility patent, an invention must be novel, non-obvious, and useful.
It's important to note that obtaining a utility patent is a complex and time-consuming process that requires a thorough understanding of patent laws and regulations. In many cases, inventors will seek the help of a patent attorney to ensure that their application meets all requirements and to increase their chances of receiving a grant.
Examples include:
- The telephone (Alexander Graham Bell's patent)
- The computer mouse (Douglas Engelbart's patent)
- The light-emitting diode (LED) (Nick Holonyak Jr.'s patent)
- The jet engine (Frank Whittle's patent)
- The barcode (Norman Joseph Woodland and Bernard Silver's patent)
- The Post-it Note (Arthur Fry and Spencer Silver's patent)
- The 3D printing technology (Chuck Hull's patent)
- The MP3 audio compression technology (Karlheinz Brandenburg's patent)
Design Patents
Design patents protect the ornamental appearance of a product, as opposed to its functional features. A design patent gives the owner the exclusive right to prevent others from making, selling, or using a design that is substantially similar to the patented design for 15 years from the date of grant.
Examples of products that can be protected by design patents include jewelry, furniture, toys, and even graphical user interfaces. To be eligible for a design patent, an invention must be original and non-obvious. Additionally, the design must be embodied in a tangible product and must not be purely functional in nature.
It's important to note that design patents provide more limited protection than utility patents. While a design patent may provide some protection for a unique look or appearance, it won't prevent others from producing similar products with a different appearance. As a result, design patents are often used in conjunction with utility patents to provide a more comprehensive level of protection for a product.
Examples include:
- The design of the Coca-Cola bottle (The Coca-Cola Company's patent)
- The design of the Apple iPhone (Apple Inc.'s patent)
- The design of the Lego brick (The Lego Group's patent)
- The design of the iconic Tiffany lamp (Louis Comfort Tiffany's patent)
- The design of the Eames Lounge Chair (Charles and Ray Eames's patent)
- The design of the original Hershey's Kisses chocolate (The Hershey Company's patent)
- The design of the Converse All-Star sneakers (Marquis M. Converse's patent)
Plant Patents
Plant patents are a type of patent that protect asexually reproduced new varieties of plants. A plant patent gives the owner the exclusive right to prevent others from selling, reproducing, or using the patented plant for 20 years from the date of grant.
To be eligible for a plant patent, a plant must be a distinct and new variety that has been asexually reproduced, meaning it has been produced through techniques such as grafting, budding, or cuttings. Additionally, the plant must not have been commercially exploited or sold more than a year before the patent application is filed.
It's important to note that plant patents are relatively uncommon compared to other types of patents, as they only cover asexual reproduction of plants. Plants produced through sexual reproduction, such as seeds, are not eligible for plant patents. Additionally, plant patents only provide protection in the United States, so international protection may require additional measures.
Plant patents provide an important form of protection for plant breeders and nurseries, allowing them to commercially exploit their innovations and recoup the costs of development. They also encourage further innovation in the field of plant breeding and provide consumers with a wider variety of plants to choose from.
It's worth noting that these are just a few examples, and there are many other types of patents and examples of patented items. Additionally, the specific requirements and laws regarding what can be patented may vary from country to country.
Examples include:
- The "Bravo" variety of strawberry plant (University of California's patent)
- The "Peace" rose (Jackson & Perkins Wholesale's patent)
- The "Crimson Crisp" apple tree (Okanagan Plant Improvement Corporation's patent)
- The "Flame Seedless" grape variety (E. & J. Gallo Winery's patent)
- The "Tomaccio" tomato variety (Seminis Vegetable Seeds' patent)
- The "Ever Red" raspberry variety (Driscoll's patent)
- The "Sweet Caroline" sweet onions variety (Sakata Seed America's patent)
- The "Sugar Snap" pea variety (Pegasus Agriculture's patent)
Conclusion
It is important to note that the information provided is for general informational purposes only and should not be relied upon as legal advice. Patent law is complex and can vary greatly from country to country. As such, it is highly recommended that you seek the advice of a qualified patent attorney when making decisions about your patent options.
A patent attorney can help you understand the specific patent laws and regulations in your jurisdiction and can provide you with guidance on which patent option is best suited for your particular invention and goals. They can also help you navigate the complex process of obtaining a patent and can assist you in avoiding potential pitfalls along the way.
