Basic Outline of a Patent Application

When it comes to writing a patent application, certain sections need to be included for the application to be complete. This section will discuss what each section should contain.

The title of the invention

First, you need to come up with a title for your invention. This title will be included in the patent application, so ensure that you're happy with it. It should be concise and to the point, accurately describing the invention.

Cross-reference the related applications

If you have filed any previous patent applications related to this invention, you must mention them here. This is known as a cross-reference, and it helps the patent office understand the history of your invention.

Background of the invention

Next, you will need to describe the invention's background briefly. This section should include information about where the idea for the invention came from and any previous attempts to create a similar product.

Summary of the invention

After discussing the background of the invention, you will need to provide a summary of the invention itself. This section should be brief, but it should still include details about your invention.

Description of the drawings

If you have included any drawings with your patent application, you will need to describe them here. This description should include information about what each drawing is showing and any important details not shown in the drawings.

Give a detailed description of the drawings

You will need to provide a more in-depth description of the drawings you included with your application. This description should include information about how each drawing relates to the invention, and it should also explain any intricate details that are not easily understood.


This section is where you will list your patent claims for the invention. There can be multiple claims, and they should all be listed in this section. Each claim should be numbered, and you should provide a brief description of each one.

Abstract and drawings

The abstract section is the final section of the patent application. It entails a summary of the entire invention, and it should be no more than 250 words. The abstract should include information about the invention, the background, and the claims. You will also need to add a brief description and a copy of all the drawings you included with your application.

Tips to Consider When Writing a Patent

When writing a patent application, it is important to remember several tips. Let's discuss each of them in more detail.

 1) Work closely with your patent attorney or patent agent

 Working hand in hand with your patent attorney can help you achieve a successful patent application. Your attorney will help you draft a clear and concise description of your invention and assist you in appropriately aligning your claims with your specifications.

 2) Ensure your description is complete

The USPTO needs to understand your invention and how it works for your patent application to be approved. Be sure to provide a clear and concise description of your invention, and include adequate details and examples.

 3) Make good use of drawings

 Proper drawings can help illustrate your invention and make the USPTO's job easier. When drawing your invention, ensure you include all relevant details and use the appropriate engineering drawings.

 4) Ensure there is clarity in your application

 Always ensure your patent application is clear and concise. Ambiguous language can often lead to delays or even rejections from the USPTO. Be sure to proofread your application for grammar and spelling mistakes and provide as much detail as possible.

 5) Align claims with specifications

 One of the most common reasons for patent applications to be rejected is when the claims are not aligned with the specifications. To avoid this, work closely with your attorney to ensure that your claims accurately reflect your invention.

 6) Use the proper filing method

 Different filing methods are available depending on what type of invention you have. For instance, utility patents must be filed through the USPTO's electronic filing system (EFS-Web). In contrast, design patents can be filed either through EFS-Web or by mailing in a paper application.

 7) Ensure to review the draft application before it's filed

 At this point, your attorney will provide you with a draft of your application for review, and it is vital to ensure that all of the details are correct before filing.

 By following these tips, you can help ensure a successful patent application.
