Introduction
A patent is a trade: you disclose your invention in enough detail that others could reproduce it, and in return you get exclusive rights. For a machine or a chemical process, a written description and drawings are usually enough. For a new bacterial strain, a cell line or a yeast, they are not, because you cannot reliably recreate a living organism from a paragraph of text. This is the problem the Budapest Treaty was created to solve.
This article explains what the Budapest Treaty is, how a deposit works and how Indian applicants use it.
What Is the Budapest Treaty?
The Budapest Treaty on the International Recognition of the Deposit of Microorganisms for the Purposes of Patent Procedure interesting. The Budapest Treaty was concluded in 1977. Came into force in 1980. The Budapest Treaty is administered by WIPO and the Budapest Treaty has, then 80 member countries.
The main rule is easy to understand: when you put a living thing into a recognized place that keeps such things all the countries that are part of the system have to accept it for use, in patents. You don’t need to send the tiny living thing to every country where you apply for a patent.
Like the Paris Convention and the PCT the Budapest Treaty is not a patent system. It does not give out patents. Decide if a microorganism can be patented. This is something that each country’s own law handles.
Why Is a Deposit Needed?
Patent offices require an enabling disclosure. An enabling disclosure means that a person skilled in the field must be able to carry out the invention, from your application. When the invention involves a microorganism that’s not publicly available and a microorganism cannot be described well enough to be reproduced the written description falls short.
A deposit fills that gap. You put a sample of the organism with a place that is known and trusted and the application talks about it. After the application is made public, other people who have a reason can ask for a sample according to the rules in the treaty. The sample is included in the sharing of information.
Before the Budapest Treaty an applicant had to place the organism in every country where they applied. This was expensive, slow and created uncertainty about which depositories each country would allow.
The Key Features of the Treaty
1. International Depositary Authorities (IDAs)
The treaty works through institutions called International Depositary Authorities (IDA). These are culture collections that have been recognized by their government and notified to WIPO. A deposit at any IDA is valid in every member country. India has IDAs of its own, including the Microbial Type Culture Collection (MTCC) at IMTECH, Chandigarh and the Microbial Culture Collection (MCC) in Pune. Check WIPO’s current list of IDAs before depositing, since the list changes.
2. One Deposit, Recognised Everywhere
One deposit, at one IDA, is enough for all member countries. This is the main saving in time and cost.
3. Minimum Storage Period
An IDA must keep the deposit for at least thirty years from the date of deposit and for at least five years after the most recent request for a sample, whichever is longer. This makes sure a sample is available, for the life of the patent.
4. Viability Checks
The IDA checks that the deposited organism is alive, at the time of deposit. It issues a statement of the result. If the sample later dies the rules allow the depositor to replace the organism.
5. Access to Samples
The treaty says when and who can get the samples from the IDA. Usually samples can go to a patent office. After the application is published they can be shared with a party. Once the patent is granted anyone who has the right, under law can get a sample. That is why making a deposit is also considered a kind of disclosure.
How a Budapest Deposit Works: A Worked Example
Suppose a Pune-based biotech startup has developed a new probiotic strain with a specific health benefit, and wants to patent the strain and its use.
- Deposit: The startup sends a pure culture of the strain to an IDA, for example one in India, along with a request for deposit under the Budapest Treaty.
- Receipt and accession number: The IDA issues a receipt with an accession number and the deposit date.
- Viability test: The IDA confirms the strain is alive and issues a viability statement.
- Reference in the application: The patent application describes the strain and cites the IDA, accession number and deposit date.
- Filing abroad: When the startup files in the US, Europe, Japan and elsewhere, or enters the PCT national phase, the same deposit is accepted, with no new deposit in each country.
Timing: When to Deposit
The treaty does not set a deadline for when a deposit must be made. This is left to each country’s law. This is where applicants most often go wrong. In countries the deposit must be made on or before the filing date and in some it can be made later within a set period. In India the requirements for material are in Section 10 of the Patents Act, 1970 and the Patents Rules so confirm the timing, with your patent attorney before you file.
The safe approach is to deposit before you file, or on the same day.
Budapest Treaty and the PCT
A PCT application can refer to a Budapest deposit, and the rules allow the applicant to give the details of the deposit in the application. The deposit then supports the national-phase filings in each country you enter. In practice, the treaties work together: PCT gives one application route, and Budapest gives one deposit route.
India and the Budapest Treaty
India acceded to the Budapest Treaty on 17 September 2001, and it came into force for India on 17 December 2001.
In practice:
- Indian biotech and pharma applicants can deposit with an Indian IDA and rely on that deposit when filing in other member countries.
- Foreign applicants whose inventions involve biological material can file in India with a deposit made at any recognized IDA.
- The relevant sectors are broad: probiotics and fermentation, vaccines, enzymes, agricultural biotech, biopharmaceuticals and cell-based products.
Common Misconceptions
“Any culture collection will do.”
No. Only a recognized International Depositary Authority counts under the treaty. A deposit elsewhere may not be accepted.
“The Budapest Treaty means my microorganism is patentable.”
It does not. Patentability is decided by each country’s law and the usual tests of novelty, inventive step and industrial applicability.
“Depositing keeps my strain secret.”
It does not. Once the application is published, third parties can request samples under the treaty’s conditions.
“I can deposit whenever I like.”
Each country sets its own timing rules. A late deposit can invalidate your application in some countries.
“One deposit covers every country in the world.”
It covers Budapest Treaty member countries only, and only for patent procedure.
How PATHtoIP Helps
PATHtoIP supports biotech and pharma clients whose inventions involve biological material:
- Advising when a deposit is needed and how it fits into your filing strategy
- Coordinating with a suitable International Depositary Authority
- Drafting applications that reference the deposit correctly
- Aligning the deposit with Paris Convention priority and PCT national-phase deadlines
Conclusion
The Budapest Treaty is a specialist treaty, but for any biotech or pharma company working with living material it is essential. It removes the need for multiple deposits and gives a standard, internationally accepted way to meet the disclosure requirement. Together with the Paris Convention and the PCT, it completes the toolkit for filing biotech patents internationally.

Frequently Asked Questions
What types of inventions need a Budapest deposit?
Inventions that use or claim a microorganism or similar biological material that is not publicly available and cannot be fully described in writing. This includes bacteria, yeasts, fungi, viruses, plasmids and cell lines.
Do I need to deposit in every country where I file?
No. One deposit at a recognized International Depositary Authority is accepted by every Budapest Treaty member country.
Who can access the deposited sample?
Patent offices, and third parties who meet the conditions in the treaty and national law. This usually begins after the application is published, and is not limited to the applicant.
