What must a patent application include? The complete guide

A competent performer without an audience is analogous to an innovation without a patent registration or award. When an inventor creates a new concept or innovation that is technically innovative but isn’t protected by the patent registration procedure, it can be replicated by others and used to their advantage. So that no one else may steal your ideas or innovation and profit from it, you must safeguard them as soon as possible.

Description of your invention

There must always be a written description of the innovation. A issued patent application may be invalidated if the description is not sufficiently clear for a person with the requisite ability to understand how to use the invention.

A succinct and accurate title of the innovation must come first in the description.

Start the description by outlining the invention’s range of use and describing the specific technical issue it resolves. Specify the solution as well. Describe the invention’s technical aspects and how it differs from existing solutions. An expert in the subject must be able to create or utilise the gadget or product based only on the description.


We advise you to upload illustrations because they frequently make the explanation easier for the reader to grasp. Each drawing page may include one or more figures, and each figure should be numbered consecutively (e.g., “Figure 1,” “Figure 2,” and so on). In order to make the description easier to follow, the image only displays the most crucial information using reference numbers or letters (for example, 1, 2a, and 2b).

No further markers beyond those indicated in the description and no descriptive text may be present in the illustrations. Short phrases like “water,” “steam,” “part A-B,” or “closed” are nonetheless acceptable.


The claims outline what is shielded by a patent, if one is granted. You should be careful while writing your claims because of this. Our patent examiners look at the claims and contrast the innovation described in them with existing solutions to determine whether your invention is patentable. To put it another way, the claims must precisely define what you want the patent to defend. Use reference numbers or letters, preferably in parenthesis, that relate to the drawings instead than referencing the description or the abstract in the claims.

Preamble and characterising part in claims

Count each assertion. The claims are divided into two sections: a prologue and a characterising section. The prologue lists the well-known elements of your creation, whereas the characterising section describes its novel and creative features. After the prologue, insert “characterised in that” or a sentence to that effect. In other words, discuss the well-known aspects of your innovation first, then add “characterised in that,” and finally describe the unique and creative aspects of your idea.


The invention’s technical difficulty, the fundamental principles through which it solves the problem, and the main field or fields of application for the invention must all be disclosed in the abstract in a manner that is simple to grasp. For example, you may integrate the Independent claims‘ substance in the abstract while still utilising language that is simple to grasp.

Deposit of biological material

If using an invention necessitates using biological material that is neither publicly accessible nor sufficiently explained in the application’s description section for an average expert to recreate the invention, then biological material must be deposited. The international Budapest Treaty is followed while depositing the biological material.
