How to Conduct a Comprehensive Trademark Public Search Online

Updated: July 15, 2026Published: July 14, 2026

Quick Answer

To conduct a trademark search, use the IP India Public Search portal to find identical or similar marks using wordmark, phonetic, or AI-based image tools. If you already have an application number, use the eRegister portal with an OTP and CAPTCHA to check its real-time status.

Key Takeaways

  • The IP India platform has two distinct portals: Public Search for finding conflicts, and eRegister for tracking specific applications.
  • Trademarks are categorized using the Nice Classification system for goods/services and the Vienna Classification for visual logos.
  • The DPIIT TM Search system (version Prod 1.2) now allows AI-powered, image-based searches by uploading a JPEG or PNG file.
  • Preserving timestamped records of your clearance searches is vital to proving you adopted your brand in good faith.

Introduction

Adopting a new brand name or logo without conducting a clearance search is a massive legal and financial risk. If you invest in marketing a brand that is already registered by someone else, you could face immediate infringement lawsuits and be forced to rebrand entirely. Fortunately, the Office of the Controller General of Patents, Designs and Trademarks (CGPDTM) provides free, digital access to the Indian trademark database. Conducting a comprehensive search via the IP India portals is the mandatory first step for any founder, creator, or legal professional before filing an application under the Trademarks Act, 1999.

When searching for trademarks, you must understand how the Registry categorizes and compares brands to determine "deceptive similarity."

Classification Systems

Trademark searches rely heavily on international classification systems.

  • Nice Classification: Groups all goods and services into 45 distinct classes. A comprehensive search must check your specific class and any closely related classes.
  • Vienna Classification: Used to categorize the visual components of a logo or device mark (e.g., shapes, animals, or colors).

The Two Portals

The CGPDTM operates two primary interfaces:

  1. Public Search Portal: Used to find a trademark and its application number using a name, phonetic string, or image.
  2. eRegister Portal: Used when you already have the application number and need to check its detailed, real-time status and history.

To ensure your desired brand name is available, follow these steps on the Public Search portal:

  1. Access the Portal: Go to the official website of Intellectual Property India, locate the "E-Gateways" section, and find the "Public Search" option.
  2. Select Search Type: Choose from Wordmark, Vienna, or Phonetic search parameters.
  3. Enter Search Parameters: Type your search term and select a match option such as "Contains" or "Starts With". It is crucial to try alternative spellings, as the platform can struggle with special characters or non-standard formatting.
  4. AI Image Search: If searching for a logo, use the DPIIT TM Search system (version Prod 1.2), an AI-powered tool where you can upload an image (JPEG, PNG) to find visually similar registered marks.
  5. Execute and Review: Enter the CAPTCHA code and click search. Review the resulting list of matching marks to identify any identical or deceptively similar brands in your class.

Step-by-Step Process for Tracking an Application

If you have already filed and want to check your status (e.g., if it is "Objected" or "Advertised"):

  1. Visit eRegister: Go to tmrsearch.ipindia.gov.in and navigate to Trade Marks -> Track Proceedings -> Track Application Status.
  2. Open a Session: Following a 2026 website revamp, you must enter a valid email or mobile number to receive an OTP, which, along with a CAPTCHA, opens the search session.
  3. Enter Application Number: Select "National/IRDI Number," enter your specific application number accurately, and click "View" to see the detailed timeline and current status.

Practical Tips: Preserving IP Evidence

  • Download Search Reports: When you conduct a clearance search before adopting a brand, save the search results as a PDF with a clear timestamp. If you are ever accused of bad-faith trademark adoption, this report proves you conducted due diligence and found no conflicting marks at the time.
  • Monitor the Journal: If you find a competitor's mark during your search that is "Accepted and Advertised," you have a strict 4-month window to file a formal opposition. Preserve a copy of that specific Trademark Journal page.

When Should You Consult a Lawyer?

  • Interpreting Results: Finding a similar name in the database does not automatically mean you cannot use your mark. An IP attorney can analyze if the prior mark is "dead," if it operates in a legally distinct class, or if it lacks distinctiveness.
  • Phonetic Conflicts: The Registry often objects to marks that look different but sound identical. A lawyer conducts complex phonetic searches to ensure your brand name won't be blocked during the examination phase.

Conclusion

A comprehensive trademark search is a critical preventative measure in IP strategy. By mastering the IP India Public Search portal for clearance and utilizing the updated eRegister portal for tracking applications, businesses can make informed branding decisions. Always preserve your search records and consult an IP professional to interpret complex results, ensuring a smooth path to securing your statutory trademark rights.
