[edit reason] Per Charter please avoid service provider references whereever possible [/edit]
Locking typically means the domain cannot be transferred and would need to be unlocked by the registrant before it can be voluntarily transferred.
There's a slight - very slight - chance the domain will simply expire and you can then freely register it.
If your interest in the domain is very high I suggest you either contact the current registrant to inquire about buying the domain or contact the existing registrar to inquire how they handle expiring domains, i.e., do they "go to auction", etc.
P.S. Re: the edit. We tend to avoid references to domain services, such as WhoIs services, particularly ones that are heavily supported by advertising and affiliate links.
