A trademark search checks the records of the trademark office to see whether the mark you want has already been applied for or registered by someone else.
The reason to do it is straightforward. The existence of prior identical or similar marks, whether pending or registered, is one of the most common grounds of refusal. Finding that out before you file costs a fraction of finding it out after you have built a brand around the name.
Office records are not the whole picture either. Prior rights in India can arise through use without registration, so it is worth searching company registrations and the internet as well.
Searching the Registry records
The IP India public search is free. It was chargeable years ago, but with digitisation the online public search is now available at no cost.
The search takes three decisions.
What kind of search. Word mark, phonetic, or Vienna code. Vienna codes cover the non-alphabetic elements of a logo, such as figures and shapes, and are the only practical way to search device marks.
Which matching criterion. Results beginning with the keyword, containing the keyword, or matching it exactly.
Which class. You need to specify the class, which means working out your classes first.
Knockout search
A knockout search looks for marks that are identical or so close that they present an obvious problem.
The purpose is to find out quickly whether there is an apparent and probable obstacle. It is fast and cheap, and it is the right first step when you are still choosing between several candidate names. If a name fails a knockout search, there is no point spending money on a full clearance search for it.
Clearance search
A clearance search is comprehensive. It looks not only for identical marks but for marks that might be considered deceptively similar.
This means searching across several keywords and combinations, including aurally similar variants, since Indian examiners and courts assess similarity by sound as well as by sight. A search will generally extend online, including domain names, to find deceptively similar marks in use.
The aim is genuine clearance before filing.
INN search
International Non-proprietary Names are the generic names for pharmaceutical substances used in the medical field. Paracetamol is an example.
INNs cannot be appropriated or owned by anyone, and no term deceptively similar to an INN can be owned either. INN stems are also protected, which catches a great many proposed pharmaceutical brand names.
If you are filing in the pharmaceutical space, search the INN list first. The list is maintained by the World Health Organization and is regularly updated. Failing to check is one of the more avoidable ways to lose a filing fee.
Company name and domain name searches
Registry records will not show a business trading under a name it never applied to register.
Because prior use can defeat a later application in India, it is worth checking:
- Company and LLP registrations through the Ministry of Corporate Affairs records.
- Domain name registrations, which often reveal use that has never reached the Register.
- General internet and marketplace searches, which pick up traders operating without any formal registration at all.
Common law search
This is the broader sweep for unregistered use: trade directories, marketplaces, social media, press coverage.
It matters because someone with earlier genuine use can oppose your application or bring a passing off action even though they hold no registration. Registry-only searches give false comfort on exactly this point.
What a search cannot tell you
A search shows you what exists. It does not tell you how an examiner will assess similarity, which involves judgment, and reasonable practitioners sometimes differ.
It also cannot capture applications filed very recently but not yet reflected in the searchable database. There is always a gap, and for high-value adoptions it is worth repeating the search closer to filing.
A search is risk assessment, not a guarantee.
Frequently asked questions
Is the trademark search free in India? The IP India public search is free. A professional clearance search carries a fee because of the analysis involved rather than the database access.
Do I need a search if my name is completely made up? It is still worth a knockout search. Coined words are the strongest marks, but coincidental adoption happens, and phonetically similar marks may already be on the Register.
What is the difference between a knockout and a clearance search? A knockout search finds obvious blockers quickly and cheaply. A clearance search is comprehensive, covering phonetic and visual similarity and unregistered use, and is what you want before committing to a brand.
How do I search a logo? Through Vienna codes, which classify the figurative elements. Word searching will not find a device mark that contains no text.
Does a clear search mean my application will be accepted? No. It substantially improves your odds and lets you assess risk, but examiners exercise judgment, and objections can be raised on absolute grounds relating to the mark itself rather than any conflict.
Should I search outside India too? If you plan to file abroad, yes. TMClass is useful for terminology, and searching the target jurisdictions early avoids adopting a name you cannot use in your main markets.
