Say, for example, you make a chip that does motion search acceleration and you want to sell it to people who do both AV1 and H.264 encoding. You'd be covered for any patents included under this license to the extent the chip was used for AV1 encoding, even though you didn't make a complete encoder. To the extent someone wanted to use it for H.264 encoding, your or they would still have to negotiate a separate license (just as you would have if AV1 didn't exist).

Source: I helped write this license.

I see, thanks! The language itself sounds eerily circular :)

That's intentional. We want to cover components that are themselves used in other components, recursively up the whole supply chain, as long as they're ultimately used for AV1.
