Basic Details You Must Have Before Filing a Patent
Before you start the patent process, you need some basic personal or business-related information that will be used in your application.
Full Name and Address
The patent office needs the applicant’s full legal name and complete address. If there are multiple inventors, you must provide the details for each one.
Applicant Type
You must know whether you are filing as:
-
Individual
-
Startup
-
MSME
-
Company or Organization
Your category helps determine the type of documents you will submit.
Contact Information
You must provide a working email address and phone number for official communication from the patent office.
Information About the Inventor(s)
The patent application must clearly mention who invented the idea or technology. This avoids future disputes.
Inventor Names
Include the full legal names of all inventors involved in creating the invention.
Inventor Contribution
Each inventor’s contribution should be clear. Even if two inventors worked on different parts, they should be listed correctly.
Nationality
The nationality of every inventor must be provided.
Details About Your Invention
This is the most important part of your preparation. The patent office needs accurate and complete details about your invention.
Title of the Invention
Create a short, clear, and precise title that describes what your invention is about. It should not be too long or too vague.
Field of the Invention
Mention the technical area or category your invention belongs to, such as:
-
Mechanical
-
Electrical
-
Software
-
Chemical
-
Medical device
-
AI or automation
This helps the patent examiner understand your invention better.
Background Problem
Explain the problem your invention solves. Why is your idea needed? What issues exist in current solutions?
Summary of the Invention
Write a clear explanation of how your invention solves the problem. Keep it simple but accurate.
Detailed Description of the Invention
For a patent to be accepted, your invention must be fully explained. The description must be detailed enough that someone skilled in your technical field can understand and reproduce it.
Step-by-Step Working
Explain how your invention works. Break it into steps if needed.
Components or Parts Used
List all elements or features included in your invention.
Technical Specifications
Provide measurements, technical parameters, or unique features that make your invention novel.
Variations or Embodiments
Mention if your invention has different versions, models, or optional designs.
If you are preparing a complete specification, these details become even more important because they form the basis of your patent claims later.
Drawings or Diagrams of the Invention
Drawings are an important part of a patent application because they help visually explain how your invention works.
Clear Diagrams
Include clear sketches or CAD drawings that represent every part of your invention.
Numbered Labels
Parts of your invention should be numbered for easy reference in the description.
Multiple Views
If needed, include:
-
Front view
-
Side view
-
Top view
-
Sectional view
These help examiners understand complex structures more easily.
Claims (For Complete Specification)
Claims define the legal boundaries of your invention. They explain what exactly you want to protect.
Main Claim
Describes the core feature of your invention.
Sub-Claims
Explain additional features or optional improvements.
Claims must be written very carefully because they determine how strong your patent protection will be. If your invention is not fully ready yet, you can start with a provisional application and file claims later when submitting the complete specification.
Patent Search Information
Before filing, it is always a good idea to do a basic patent search to check whether similar inventions already exist.
Similar Existing Patents
Identify any inventions related to yours and understand how they differ.
Novelty Check
Ensure your invention is new and unique. Even small similarities can affect your application.
Improvement over Prior Art
Explain how your idea is better or different from existing solutions.
A prior art search helps you avoid rejection and strengthens your application. If you need help with this, you can contact us for expert guidance.
Supporting Documents You May Need
Depending on who is filing the patent, you may also need some supporting documents.
ID Proof
Aadhar card, PAN card, or passport.
Address Proof
Utility bills, Aadhar, rental agreement, etc.
Startup or MSME Certificate
If you are filing under these categories, the certificate may be required.
Assignment Deed
If the applicant is a company but the inventor is an individual, ownership can be transferred through an assignment deed.
