Key Takeaways

  • A patent gives inventors exclusive rights to their inventions, protecting them from unauthorized use or sale.
  • Applying for a patent requires verifying patentability, conducting thorough research, and preparing a detailed application.
  • Provisional patents offer temporary protection while you refine your invention.
  • Costs can include government fees, attorney fees, and research costs, and vary based on the complexity of your invention.
  • Filing internationally or through the Patent Cooperation Treaty (PCT) can protect your invention in multiple countries.
  • A well-prepared application and timeline awareness are crucial to avoiding rejections and missed opportunities.

What Is a Patent?

Before learning how to apply for a patent, you have to first understand that a patent is a property right that gives you, as an inventor, the right to sue others who try to use, make, or sell your invention without your permission. According to US law, only the inventor of an item can file a patent application for it.

If you want to protect your invention from thieves, you need to file a patent application with the United States Patent and Trademark Office. However, before you prepare the application, you should make sure your invention is patentable, perform research, and hire a qualified attorney.

There are three main types of patents that you may choose to apply for:

  • Utility patents are the most common. They cover inventions that have a specific function. Software patents are a type of utility patent, though some people place them in their own category. A utility patent is valid for 20 years after you file the application (or for 17 years after the application is approved, whichever is longer), but only if you submit the required maintenance fees.
  • Design patents cover non-functional parts of items, such as aesthetic features. A design patent is valid for 14 years.
  • Plant patents protect new plants.

Do not mix patents up with other parts of intellectual property law, such as trademarks and copyrights. Each of these is governed by different laws.

Also keep in mind that once your patent is approved, it doesn't mean it will stay valid. Another business may challenge your patent, and a court may determine that it isn't enforceable.

Why Are Patents Important?

Patents grant a limited monopoly on certain products, and this encourages inventors to come up with new ideas. Without patents, innovation would suffer.

Are There any Reasons Why You Would Choose not to Patent Your Invention?

One reason you might choose not to patent your invention is because your idea isn't patentable. There are a few reasons why an invention might not qualify for a patent:

It Is Not Unique Enough

To qualify for a patent, an invention must be novel, meaning that it must be in some way be different from prior art. Prior art refers to past patented inventions. In order to find out if your invention meets the novelty requirement, you will have to do extensive research. You can search the Patent Database and Patent Application Database online. You should also look at scientific journals in your industry.

Having a well-rounded knowledge of prior art in your industry will help you with the patent application because you will be able to thoroughly describe how your invention is different from or improves upon past inventions.

It Is Obvious

Patented inventions must be unobvious. Someone with average skill in your industry should not view your invention as obvious.

You Do Not Have an Invention

Ideas do not qualify for patents; only inventions do. Therefore, you should be able to give a detailed description of your invention and how it works.

Even if your invention is patentable, you might not want to pursue a patent if your invention has limited commercial value. If you perform research and find that there is little to no demand for your invention, you will save money by not getting a patent.

Alternative Strategies to Patents

While patents offer strong legal protection, they aren’t always the best fit for every inventor or business. Alternatives include:

  • Trade Secrets: Instead of disclosing your invention through a patent, you may choose to keep it secret. This is ideal for formulas, processes, or methods that are hard to reverse engineer.
  • Copyright or Trademark Protection: Some aspects of your invention, like branding or software UI, may be more appropriately protected through other forms of intellectual property.
  • Defensive Publishing: By publicly disclosing your invention, you can prevent others from patenting it, effectively placing it into the public domain.

These alternatives can be cost-effective or offer strategic advantages depending on your business goals and the nature of your invention.

How Can You Apply for a Patent?

To apply for a patent, you must:

  1. Be sure that your invention is patentable. It must be different from previously patented inventions, and you must be sure that you have an invention rather than just an idea.
  2. Perform patent research. You can hire someone to help you with this, or your attorney can contact a professional researcher. This research will help you describe how your invention is different from prior art, and looking at past patent applications can give you a feel for how your application should look.

  3. Fill out your patent application. The application has a few parts:

    • The specification. In this section, you'll give enough details about your invention that someone with average skill in your industry would be able to make your invention based on your instructions. The specification includes:
      • An abstract, which is a brief preview of the rest of the specification. You can also mention your invention's title.
      • Background information, which outlines what need your invention fills or what problems it solves.
      • A summary, or a brief explanation of your invention and what it does.
      • A detailed description of your invention. It should discuss the field the invention belongs in and give information on how someone might construct the invention. It should also state the industrial application of the invention.
      • A conclusion that sums up the advantages of the invention.
      • Drawings of your invention. You can hire a patent illustrator to help you with this. In the specification, you can include notes on the drawings.
      • Claims. Claims describe which parts of your invention you want to be protected by the patent. There can be both independent claims and dependent claims. Dependent claims are connected to the independent claims. Your lawyer can give you guidance on how narrow or broad your claims should be.

    You can submit your application via mail or fax but eFiling is easier.

    Along with your application, you should also send:

    • Filing fees
    • A patent application declaration, which says that you truly invented your product
    • An information disclosure statement, which provides any extra relevant information. For example, you can talk about patent applications that you know are similar to yours
  4. If you wish, submit a non-publication request. If you do not submit this, the USPTO will publish your application 18 months after you submit it.

  5. Communicate with the USPTO. A single patent examiner will be assigned to your case, and you or your attorney will be in touch with this person as they consider your application.

    Applications are rarely approved on the first try. The USPTO may issue a non-final rejection or a final rejection. Each of these requires different legal steps that your lawyer can help you with. Common reasons for rejection are that an invention is too obvious or that the application didn't provide enough detail. If your application is rejected twice, you can file an appeal with the Patent Trial and Appeal Board.

Understanding the Patent Filing Timeline and Process Stages

The process to apply for a patent doesn’t end with submission. It unfolds in key stages:

  1. Filing Date Assignment: Once your application is submitted, the USPTO assigns a filing date. This date is critical for establishing priority over similar applications.
  2. Initial Review: The USPTO checks if all required documents and fees are included.
  3. Patent Examination: A patent examiner is assigned to assess novelty, non-obviousness, and usefulness.
  4. Office Actions: You may receive an “office action,” which could include objections or rejections. You'll need to respond within the set time (usually 3-6 months).
  5. Amendments: You can modify claims or provide arguments to overcome rejections.
  6. Final Rejection or Allowance: If objections persist, a final rejection is issued. Otherwise, the patent is allowed.
  7. Issuance and Maintenance: Upon allowance and payment of issue fees, the patent is granted. Maintenance fees are required at 3.5, 7.5, and 11.5 years for utility patents.

Patent approval may take 1 to 3 years depending on the type of invention, the USPTO’s backlog, and complexity.

What if You're Not Ready to Apply for a Patent?

Provisional Patent Applications

If you want to protect your invention but aren't yet ready to dive into the patent application process, you may want to consider submitting a provisional patent application. A provisional application is affordable, costing only $130 in filing fees for micro entities, $130 for small entities, and $260 for larger businesses.

Once you submit a provisional patent application, you can say that your invention is "patent pending," which warns away anyone who might be thinking about stealing your idea. A provisional patent application is more affordable than a non-provisional application. It lasts for 12 months, and you can use this year to perfect your invention and prepare to submit a non-provisional application.

A provisional application is simpler than a non-provisional one; it requires fewer details about your invention. However, you should be as detailed as possible. Being too broad could mean that your provisional application gets rejected.

Out of the most outstanding things about the provisional patent application is that it gives you an advantage according to the law. In the US, patents are granted on a first-to-file basis, not on a first-to-invent basis. This means that the sooner you stake your claim, the less likely it is that someone will steal your invention and get a patent on it before you can.

Here are a few tips to keep in mind when you're writing your provisional application:

  • The description of the invention should be detailed enough that someone else could build the invention based on your description. You'll also need to include a drawing of your invention.
  • Be careful with the language in your description. Avoid words like "must" and "necessary."
  • Make sure your description is accurate but not too specific. This leaves you a little wiggle room to tweak your invention during the provisional period. Remember that any part of your invention not included on the provisional application is not protected by it.

Common Mistakes to Avoid When Applying for a Patent

Applying for a patent involves detailed legal and technical documentation. Avoid these pitfalls to improve your chance of approval:

  • Insufficient Prior Art Research: Not identifying existing patents or published works can result in rejections for lack of novelty.
  • Overly Broad Claims: Claims that are too general can be easily rejected for being obvious or encompassing existing technologies.
  • Lack of Detail in Specification: The application must enable someone skilled in the field to reproduce the invention. Vague descriptions often lead to rejection.
  • Missing Deadlines: Failing to respond to office actions, file maintenance fees, or convert a provisional application within 12 months can invalidate your efforts.
  • Failing to Keep Invention Confidential: Public disclosures, such as product launches or investor pitches, may compromise patent rights if a patent hasn't been filed beforehand.

Avoiding these errors often requires expert review. Consider consulting an intellectual property attorney, especially if the invention has high commercial potential.

How Much Does It Cost to Get a Patent?

It is next to impossible to guess how much you will have to pay to get a patent. However, you should be prepared to spend at least a few thousand dollars. There are three main costs you need to consider:

  • Government Filing Fees: The USPTO has its filing fees posted online. If you are a small entity, such as a university or a small business, your filing fee will be at least $140. For larger businesses, the basic filing fee starts at $280. You'll also have to pay search fees of $300 for small entities and $600 for larger businesses if you want a utility patent. You'll have to pay even more if your application has a lot of pages or if you originally wrote it in a language other than English and it needs to be translated.
  • Attorney Fees: How much you'll pay your attorney depends on a few things, including how complicated your invention is.
    • For simple inventions, you can expect to pay between $5,000 and $7,000 to your attorney.
    • For relatively simple or minimally complex inventions, you might pay between $7,000 and $10,000.
    • For moderately complex or relatively complex inventions, your fees could be between $10,000 and $14,000
    • For highly complex inventions and software, you could pay between $14,000 and $16,000. Sometimes, you will have to pay even more.
  • Research Fees: You can start patent research on your own, but hiring the help of a professional is wise. A patent researcher knows how to navigate patent databases and can give you a detailed report on existing patents that may affect how the USPTO reacts to your application. Research fees for simple inventions may be around $1,000. For more complex inventions, such as software, you may have to pay up to $3,000.

These fees are so high because many patent attorneys have knowledge that extends beyond the law. They may have technical expertise that gives them the ability to understand your invention.

Applying for an International Patent

If you plan to market your invention globally, you may want to apply for patent protection in other countries.

There are two primary options:

  1. Direct National Filing: You apply individually in each country where you seek protection. Most countries require this within 12 months of your initial U.S. filing under the Paris Convention.
  2. Patent Cooperation Treaty (PCT): This allows you to file one international patent application, which reserves your right to pursue protection in over 150 participating countries. The PCT doesn’t result in an international patent but streamlines the process by delaying national filings for up to 30 months from the original filing date.

International applications involve translation costs, country-specific fees, and may require local legal representation. Strategic planning is crucial to decide which markets justify the investment.

Frequently Asked Questions

  1. Can I apply for a patent if my invention is still a prototype?
    Yes, as long as your invention is fully conceptualized and you can describe how it works in detail, you can apply—even without a finished prototype.
  2. What’s the difference between a provisional and non-provisional patent?
    A provisional application is a temporary filing that establishes an early filing date and lasts 12 months. A non-provisional application starts the official examination process.
  3. Do I need a patent search before applying?
    While not required, a thorough search helps identify similar inventions and can strengthen your application by showing how your invention is unique.
  4. What happens if I miss the 12-month window after filing a provisional patent?
    You lose your priority date and must refile, which could result in losing patent rights if someone else files in the meantime.
  5. Is patent protection worldwide?
    No, patents are territorial. You must apply in each country or region where you seek protection, or use the PCT system to streamline international filing.
