An inventor is required to deposit the strain of a microorganism in a recognized depository which assigns a registration number to the deposited microorganism. This number needs to be quoted in the patent application. Obviously a strain of microorganism is required to be deposited before filing a patent application.
It may be observed that this mechanism obviates the need of describing a microorganism in the patent application. Further, samples of strains can be obtained from the depository for further working on the patent. There are many international depositories in many countries, which are recognized under the Budapest Treaty.
A Patent is a statutory right for an invention granted for a limited period of time to the patentee by the Government, in exchange of full disclosure of his invention for excluding others, from making, using, selling, importing the patented product or process for producing that product for those purposes without his consent.
