What characterises a BiOS-compliant agreement?
Usually, licenses for patented technology impose strict conditions on the user, commonly involving fees or royalties for use of the materials or methods or both. Materials Transfer Agreements (MTAs) typically impose the condition that the technology may only be used for certain purposes, often not allowing the development of products.
Instead of royalties or other conditions that disfavor creation of products, under a BiOS-compliant agreement, in order to obtain the right to use the technology the user must agree to conditions that encourage cooperation and development of the technology.
These conditions are that licensees cannot appropriate the fundamental "kernel" of the technology and improvements exclusively for themselves. The base technology remains the property of whatever entity developed it, but improvements can be shared with others that support the development of a protected commons around the technology, and all those who agree to the same terms of sharing obtain access to improvements, and other information, such as regulatory and biosafety data, shared by others who have agreed.
To maintain legal access to the technology, in other words, you must agree not to prevent others who have agreed to the same terms from using the technology and any improvements in the development of different products.
