Many patent and trade mark agents in the UK were taken by surprise in the New Year to discover that they were ABS because someone other than a regulated person had an ownership interest. I understand that if you unwind this IPREG won't be pursuing you for illegal trading so there is likely time for agents to buy back the shares from their spouses or retire incoporated partners.
For the gospel on this do call the IPREG to make sure you have done it right.
