What are the specific circumstances requiring biological material deposit for patent applications?

Specific circumstances requiring biological material deposit for patent applications include:

• When the biological material is not known and readily available to the public
• When the invention cannot be practiced without access to the biological material
• When words alone cannot sufficiently describe how to make and use the invention

According to MPEP 2404: “The invention may rely on biological material which is known and readily available to the public or reproducible from the written description.” However, if these conditions are not met, a deposit may be necessary.
