What Is a Patent?
Before understanding the steps of filing, it’s important to have a clear understanding of what a patent is. A patent is a legal document granted by the government that gives the inventor exclusive rights to make, use, and sell their invention for a set period, typically 20 years.
This legal protection makes sure that others can’t duplicate your invention or sell it without your permission. There are different types of patents, but the most common ones are utility patents, design patents, and plant patents.
Types of patents:
Utility patents: These are the most common and cover new inventions or discoveries of processes, machines, manufactures, or compositions of matter. They also cover improvements to existing inventions.
Design patents: These protect the ornamental design of an invention, which might include the unique look of a product.
Plant patents: These are for inventors who have discovered or created new and distinct varieties of plants that can be asexually reproduced.
It’s important to identify which type of patent applies to your invention, as this can impact the application process and the protection you receive.
Steps to Filing a Patent Application
Filing a patent application can seem overwhelming at first, but breaking it down into manageable steps makes it more approachable. There are several key stages involved in filing a patent, from the initial idea to submitting the final application.
1. Confirm Your Invention Is Patentable
Before you even begin the application process, you need to make sure that your invention is patentable. The U.S. Patent and Trademark Office (USPTO) has specific requirements that your invention must meet in order to qualify for patent protection. The most critical aspects of patentability include:
Novelty: Your invention must be new, meaning it hasn’t been publicly disclosed or known before.
Non-obviousness: The invention mustn’t be obvious to someone skilled in the field based on prior art.
Utility: The invention must be useful and serve a practical purpose.
You can do an initial search to see if your invention is similar to anything already patented by searching patent databases, such as the USPTO’s database or Google Patents. While a professional search is recommended, this step can help you determine if it’s worth pursuing further.
2. Document Your Invention Thoroughly
Once you’ve confirmed that your invention may be patentable, the next step is to document your invention. This process helps to establish a record of when you created the idea and the steps you took to develop it. This can also be critical if there’s ever a dispute about who owns the invention.
Detailed description: Write down everything about your invention, including how it works, its purpose, and any unique features it may have.
Diagrams and drawings: Include sketches or diagrams of the invention. For patent purposes, your drawings must meet specific guidelines, so they should be clear and accurate.
Prototype: If possible, build a working model or prototype of your invention. While this isn’t required for all types of patents, it can make it easier to explain and demonstrate your invention.
This documentation not only helps clarify your invention but also provides the necessary details for your patent application.
3. Decide on the Type of Patent Application to File
Once your invention is well-documented, it’s time to decide whether to file a provisional patent application or a non-provisional application. Each option has its benefits, depending on your situation.
Provisional patent application: This type of application is less formal and doesn’t require claims, which can make it faster and cheaper to file. It grants you a filing date and gives you 12 months to file a non-provisional application. However, it doesn’t grant you a patent right. It’s a good option if you need more time to develop your invention or find investors.
Non-provisional patent application: This is the more formal option and will be examined by the USPTO. It includes detailed claims that define the scope of your invention’s protection. Once approved, you’ll receive a patent for your invention.
A provisional patent application can give you a head start, but a non-provisional application is required to actually secure patent rights.
4. Prepare Your Patent Application
Preparing your patent application is one of the most important steps in the process. A well-prepared application increases the likelihood of approval and helps make sure that you’re fully protected.
Patent claims: These are the most crucial part of your application. Claims define the scope of protection for your invention and must be written carefully and accurately. This is an area where an experienced patent attorney can be invaluable.
Patent drawings: Include clear, professional drawings that show your invention’s design or how it works. The USPTO has specific requirements for these, so it’s important to follow their guidelines.
Patent specification: This is a detailed description of your invention, how it works, and how it differs from existing inventions. It should clearly explain why your invention is novel and non-obvious.
Your application should be as thorough as possible to avoid delays or rejections.
5. File Your Patent Application with the USPTO
After your application is prepared, it’s time to file it with the USPTO. You can file online through the USPTO’s website using their Electronic Filing System (EFS-Web). When you file, you’ll need to pay the appropriate filing fees. These fees can vary depending on the type of patent you’re applying for and the size of your entity (individual, small entity, or large entity).
Small entity: If you qualify as a small entity, such as an independent inventor or small business, you may be eligible for a reduced filing fee.
Large entity: Larger companies or corporations will pay the full filing fee.
Once your application is submitted, the USPTO will assign an examiner to review your application. The examination process can take several months to several years, depending on the intricacy of the invention and the current workload of the USPTO.
6. Respond to Office Actions and Refine Your Application
The USPTO examiner will review your application and may issue an office action, which could involve objections or rejections based on issues like clarity, patentability, or the scope of your claims. It’s important to carefully review these office actions and respond within the given timeframe.
Amend your claims: If necessary, you may need to modify your claims to address the examiner’s concerns or to narrow your invention’s scope.
Provide additional information: You may be asked to provide further clarification or evidence to support your invention’s novelty and utility.
This back-and-forth process can take several months, but it’s an essential part of the patenting process.
7. Receive Your Patent
If the examiner is satisfied with your application and no further issues arise, you’ll receive a Notice of Allowance, indicating that your patent will be granted. Once you pay the issue fee, your patent will be issued, and you’ll have full rights to your invention.
8. Maintain Your Patent
After your patent is granted, it’s important to maintain it by paying maintenance fees at regular intervals. These fees are typically due at 3.5, 7.5, and 11.5 years after the patent is granted. Failure to pay these fees can result in the expiration of your patent.
