Invaluable To: Standard Pattern
Invaluable To: Standard Pattern records a directly documented English construction and keeps guidance bounded to the evidenced pattern rather than turning one attested complement into a universal prohibition.

Quick tests
Meaning / construction test
Are you saying something is extremely useful to a particular person, group, or effort?
If yes: Use “invaluable to” before the beneficiary or activity.
If no: Use “valueless” or another word if you literally mean that something has no value.
Caveat: “Invaluable” conventionally means extremely useful or valuable, not “without value.”
