Manual of Patent Practice
Requests under 23(1) for a foreign filing licence are dealt with quickly (a matter of days), and can be approved by sending the claims only.
Applications with joint proprietors, one being non-UK, may cause difficulties if s22 applies, i.e. conflicting security provisions.
Err on the side of caution if there is any suspicion that a licence might be required, i.e. either wait six weeks or apply to the UKPO for a licence.
