The Importance of a Preliminary Patent Application Example

As an inventor, a preliminary patent application example can be an invaluable resource to get you started. It provides guidance on how to structure your application and what information should be included.

Additionally, it provides insight into the contents of a full patent application and indicates whether yours is ready for filing.

Detailed Description

A preliminary patent application example offers you the unique chance to get your invention accepted before filing a full, non-provisional patent application. This gives you an advantage in assessing its commercial potential without investing a great deal of time or money into filing the application. Furthermore, having an early filing date can be advantageous if you want to be the first one to showcase it to others.

When filing either a provisional or non-provisional patent application, it is essential to provide comprehensive descriptions of your invention. These should be written in an understandable way for non-technical individuals and should include all essential aspects of the product.

Your invention’s description should encompass all parts and explain their interactions. Furthermore, it should outline how your invention is organized.

Many inventors attempt to describe their invention using industry-specific terms. Unfortunately, this can be difficult for others to comprehend, so it’s best to use straightforward language that other professionals in the same industry will understand.

As you write the Detailed Description, use your invention’s outline as a guideline. Doing this will help ensure that you do not describe any part of your invention in great detail that is not essential to the reader.

Include your drawings in this section, preferably with reference numerals if possible. Doing so will enable the reader to follow along with your invention as it is being organized.

Furthermore, you should thoroughly describe the features of your drawings so that the reader understands what your invention does and how it functions.

If you are uncertain of what to include in this section, consulting a patent attorney is recommended. They can review your description and draft claims accordingly.

A successful patent application should be written in an understandable language for investors, examiners and judges. It also needs to convince them that your invention has merit and should be protected – this could mean the difference between winning a lawsuit and having your invention stolen by a competitor.


Abstracts are one of the first things a patent office examines when reviewing applications. They also serve to attract potential licensees for your invention. Crafting excellent abstracts is essential in getting your patent application approved.

The abstract must provide technical disclosure of the invention, including all novel aspects that have not been previously disclosed. Furthermore, it should not compare the invention with prior-art and be very concise in nature.

A suitable patent abstract should not exceed 50 to 150 words and no more than 15 lines in text. It should avoid legalese such as “means,” and encompass what is new in the field.

If you are having difficulty creating an abstract, consider consulting a patent firm for assistance. They can craft an organized and concise abstract that is both unique and effective.

Furthermore, they can help you steer clear of common errors and guarantee your patent application is filed correctly. A well-crafted abstract can make all the difference in getting accepted by USPTO or being rejected.

Another essential consideration when writing abstracts for patent applications is to exclude information regarding purported merits or speculative applications. Doing so could lead to rejection by an examiner based on these statements.

Furthermore, avoid including extensive mechanical and design details in your abstract. Instead, focus on outlining the key technical aspects of your invention with references placed between parentheses.

The abstract is an essential component of your patent application and should be written in plain language for everyone to comprehend. To make the abstract more generalized and easier to comprehend, try using simpler language.

Additionally, ensure your abstract does not contain any enabling disclosures which could potentially lead to an invention. Otherwise, it could be considered prior art in certain circumstances.


Claims are the most crucial component of a patent application. A claim is an official legal clause that conveys to the reader (and patent examiner) what an inventor claims ownership of. Claims form the foundation of successful patent applications, so make sure you devote sufficient effort into them.

Your preliminary patent application’s description section must provide a thorough, precise and up-to-date overview of your invention. This description will be used by the patent office during their examination of your full application, so make sure this section is well written.

When writing the description for your invention, try to convey it in a straightforward and understandable manner for those outside your industry. Furthermore, avoid using legal structures or terminologies if possible.

Define how your invention differs from existing products on the market. This is especially critical if you are disclosing a product, as the patent office needs to know that it is unique and not simply an adaptation or copy of another existing item.

Your description should be able to clearly explain your invention to someone knowledgeable in the art, so using flow charts and diagrams is recommended. These will enable you to showcase your invention step-by-step, with detailed explanations of what the user does and how various elements come together for success.

Once you have written a thorough description, it is time to craft your claims. It is wise to include at least one claim in your provisional application; however, many attorneys suggest adding multiples so as to guarantee an early priority date for any subsequent nonprovisional applications filed.

Before writing your application, the team should compile a list of all prior art that was known to them. This should include all patents and products related to your invention, even those you haven’t yet disclosed.

In addition to your list of references, you should write a brief paragraph outlining what is new about your invention. This is an essential component of your preliminary patent application since it will be the first thing the patent office examines when assessing whether or not to grant you protection.


Patent drawings are essential components of a patent application. They help your examiner visualize your invention in an understandable and visual way. Drawings should be created using various techniques according to USPTO guidelines for each type of patent being filed.

Ink drawings are an age-old method for depicting inventions. They can be created manually or with modern computer-aided design (CAD) programs. If your concept is complex, CAD software can help you produce accurate and clear visuals of your creation without having to hire a professional drafting team at great expense.

You can save time by tracing photographs of your invention onto paper to highlight its features. However, bear in mind that photographs do not provide as much detail as drawings do, so they cannot substitute for them.

Standard views that can be used to demonstrate your invention include front, back, left, right and top views. You may also include perspective views. Each view should be on one page with the same orientation (landscape, portrait or angled).

The views must be numbered and drawn logically in sequence. For instance, the first view should represent your invention’s main structure, and subsequent drawings should detail specific functions and uses for each element or feature from that first view.

An exploded view is another common type of view, which displays components too small to fit on a fixed drawing. These views can be useful when illustrating the structural connection between multiple pieces in a complex mechanical device.

Your patent drawings should also include flowcharts and other diagrams to illustrate your invention’s processes or software. Doing so gives an examiner a more complete overview of the entire procedure.

Even though not required by the patent office, it’s wise to include an abstract in your patent drawings. Doing so will enable your examiner to more accurately interpret your patent and prevent any mistakes when reviewing its claims.
