How to Write a Patent Usa Application

There are some essential elements to include in a patent application. In this article, we will discuss the Enablement requirements, Claims, Functional language, and Drawings. After you have understood these elements, you will be able to write a patent application that is both effective. We’ll also discuss what you should avoid when writing your patent application. We’ll also discuss some of the most common mistakes that people make, so that you can ensure that you’ll be able to make the right decisions for your business.

Enablement requirements for a patent application

One of the most important aspects of a patent application is determining whether the claimed invention is enabled. Enablement involves describing the method by which a person skilled in the art may make the claimed invention. Enablement may also refer to an element or combination of elements that are necessary to realize a claimed invention. Enablement may be limited to a single use, but it must bear a reasonable relationship to the claim.

The application must be capable of demonstrating how the invention would work in practice. In addition to providing the invention description, the applicant must provide “working examples” and “prophetic examples” to show how the claimed device might be implemented. The former must demonstrate how the claimed circuits can be interconnected to produce the desired results. However, these examples may not be sufficient in all cases. The applicant should cite relevant technical publications that demonstrate the practical utility of the invention.

For example, in the case of an anti-cancer drug, an anti-cancer antibody, which is made from a recombinant of the human immunodeficiency protein Fabry syndrome, requires a “how to make” instruction. The specification did not explain how the complex elements would work in the Appellant’s system, but the applicant could prove that they work under reasonable conditions by demonstrating a sufficient amount of experimental work.

The scope of a claim must be considered in relation to the extent of enablement. It must be capable of protecting the inventor. In reGunn, the claimed invention had a new limitation that was not described in the disclosure. Moreover, the claims were broad and failed to protect the full scope of the claimed invention. Therefore, it is important to analyze all aspects of an invention.


The first step in writing a patent claim is to identify the subject matter of the invention. Then, you must identify the technical features that are required to define that subject matter. Otherwise, you are simply describing a combination of features that form part of the prior art. If you are writing a claim for a method, the characterizing portion should describe the steps involved in the process. Once you’ve defined what your invention is, you can move onto drafting your claims.

Claims are one of the most challenging parts of a patent application. You’ll need to ensure that they’re clear, specific, and logical. The claims must also be written in technical language, with strict grammatical requirements and technical terminology. Here are some tips for writing a patent claim:

Unless the claimed feature is completely new, it must be implemented first. The inventor must have a good understanding of the subject matter, and the claims should be clear and concise. This way, the patent examiner will be able to evaluate the novelty of the invention and determine whether it’s patentable. A patent application must also be submitted with a full patent application. The patent examiner may reject one or more claims if they don’t think the invention is new.

Whether to use two-part or one-part claim formats depends on the context of the application. Two-part claims, or ‘555-style claims, are commonly used in Europe and the USA, but are only used in special circumstances. In India, however, the patent office generally nudges applicants to redraft their claims using a two-part format. In general, two-part claims are better for a patent application if they don’t compromise the clarity of the claims or characterization.

Functional language

When drafting a patent claim, functional language should be evaluated to determine whether it is purely functional, or if it’s also partially or fully functional. Functional language may be purely functional if its purpose is merely to describe a process, or it may be partially functional if the claim is more general in nature. The recitation of structures in functional claims can raise concerns if they’re too specific.

A means plus function claim is allowed if the structure of the claimed invention relates to the claimed function. This is also called “means-plus-function” language, and applies to both methods and devices. It is important to disclose the structure associated with the functional language in the claim. Otherwise, it is deemed indefinite. In this case, the court held that the claim was invalid because of its indefiniteness.

Using functional language in a patent claim can also be acceptable in certain circumstances. For example, the use of “screwdriver” is a portmanteau term that derives from the German word schraubenzieher and the French word tournevis. Using “screwdriver” does not limit the claim to only the invention that is described. However, it may be acceptable if the claim relates to the patented invention only.

The Federal Circuit has viewed functionally claimed inventions with varying degrees of skepticism. Federal courts have also rejected functional claims. If the claimed structure is not disclosed in the patent specification, it’s indefinite. This case illustrates the need to be clear in claiming an invention. Even though functional language may be interpreted as a “use” claim, it requires additional disclosures to avoid invalidity.


Unlike descriptions, patent applications require drawings to explain what is being claimed. To submit an effective patent application, drawings must depict each feature of the invention in a particular form. The United States Patent and Trademark Office (USPTO) has strict rules regarding the size, margins, and style of the drawings. Furthermore, the drawings must be complete and correct, as they protect the invention’s design. If the invention requires complex construction, drawings must depict it.

Patent drawings are necessary to capture how the invention works in the real world. These images will show how it works and what parts it has. When creating patent drawings, make sure to include identifying indicia at the top of each sheet. Graphic forms must also meet the same requirements as drawings. During the first filing, it is mandatory to include all drawings. After that, new material cannot be submitted. However, if the inventor plans to file a follow-up application, they must provide a copy of the drawings they used for their first patent.

Drawings should include as many views as necessary to convey the invention’s details. These views may be plan, elevation, section, perspective, or detail views of individual elements. Views must be grouped together, separated by dashed lines, and preferably, should not be overly similar. The arrows and other symbols must be legible and easy to read. Applicants should avoid using a sloping or curving line to depict the parts.

In addition to these three types of drawing, the specification must contain all the necessary information to properly explain the invention. The drawings must be created using a process that provides satisfactory reproduction characteristics. In addition to being legible, the lines should be sufficiently thick and durable. If there are spherical or cylindrical elements, they should be shaded to illustrate the surface or shape of the object. Symbols are permitted, but they should have a universal meaning within the relevant art.

Response to objections to a patent application

In response to objections to a patent application, the inventor must provide evidence to support his or her claim. While the examiner’s opinion is a final decision, the response is still the applicant’s best chance to establish the patentability of his or her invention. Failure to respond in time may result in the abandonment of the patent application. The inventor can either accept the objections or amend his or her application in order to gain patent protection. In either case, the USPTO will grant the patent if the inventor meets the requirements.

A response to objections to a patent application is also known as an office action. It is a formal document prepared by the patent examiner. Typically, two or three office actions are issued before the patent is granted. A respondent should be aware of the tech-legal language that should be used when responding to objections. While writing the response, the applicant must modify the claim elements that are being objected to. Additionally, the respondent should be able to use analytical and logical reasoning to address the objections.

The first step in preparing a response to objections to a patent application is to identify the types of rejections. The two most common are obviousness and novelty rejections. In response to these objections, it is important to understand the Broadest Reasonable Interpretation (BRI) standard. This standard permits a broader meaning to words. For example, “bicycle pedal” might encompass any type of foot support. Also, “trigger” could include any type of mechanical device or actuator.

Upon receiving an objection, the patent examiner may decide to grant the patent in a timely manner. If the examiner deems that the patent application is patentable, the applicant can request continued examination to further protect it. If all goes well, the patent office will grant the patent to the applicant and the patent will be issued. A failure to respond to the objections to a patent application may result in the abandonment of the patent application.
