Perpetual licence

A licence with no end date. The know-how licence in clause 2.2 is perpetual and irrevocable, because a factory cannot unlearn how it makes its pumps. It covers only the existing range, and even a leak of the Know-How cannot end it (clause 12.4). Licence 2.2 · Chapter 2 · see Know-how

Explained in Chapter 2, The Grant: What, Where, How Long, of IP Licensing.

How it comes up, in Chapter 2
A perpetual licence has no end date. “Irrevocable” means the owner cannot simply take it back. Clause 12.4 adds that even a breach does not let the owner end it. Chapter 5 shows what the owner can do instead if the factory leaks the know-how.
