Inventions are the lifeblood of scientific and technological progress, driving continuous innovation and propelling society forward. To protect inventors and their groundbreaking ideas, patents play a crucial role, offering legal protection and encouraging further pursuit of ingenuity. Understanding the different types of patents available is essential for any aspiring inventor. Let’s explore various patent classifications, their particular characteristics, and how services like InventHelp can aid inventors in obtaining the appropriate form of patent protection for their innovation.

An Overview of Patent Types

What are the different types of patents? Contrary to popular belief, there is not a ‘one size fits all’ patent. The United States Patent and Trademark Office (USPTO) recognizes three main types of patents: utility patents, design patents, and plant patents. Each category encompasses varying degrees of invention protection and has unique requirements.

1. Utility Patents

Utility patents are the most common type of patent and protect the functional aspects of an invention or discovery. A utility patent covers:

New and useful machines or mechanical devices (e.g., engines, tools).

Manufactured products (e.g., chemical compositions, textiles).

Processes or methods (e.g., software solutions, manufacturing techniques).

New and useful improvements of existing inventions or discoveries.

Utility patents provide legal protection for a duration of 20 years from the filing date, contingent on the payment of maintenance fees. It is essential to note that a utility patent pertains to the invention’s functionality, not its outward appearance or aesthetics.

2. Design Patents

Design patents, focusing on the ornamental aspects of a product, protect the aesthetic features of an invention. In contrast to utility patents, design patents shield the visual characteristics that make an invention or design visually distinct from others. Their primary purpose is to safeguard the unique appearance and non-functional features, such as contours, patterns, and configurations. A design patent offers protection for 15 years from the issuance date, and unlike utility patents, they do not require maintenance fees.

3. Plant Patents

Plant patents are a specialized category of patents. As the name suggests, plant patents offer protection for asexually reproduced plants that are botanically distinct and novel. This ensures the inventor’s exclusive right to propagate, use, or sell the newly discovered or invented plant. Plant patents remain valid for 20 years from the filing date, and similar to design patents, they do not require maintenance fees.
