It is common for people to buy and park domain names that may be useful for organisations or other big spenders in the future. For example, if today I buy a domain named WorldCup2020.com for as cheap as Rs.300 and keep it idle until 2020. Organisations/Companies seriously looking out for this domain would contact me and be willing to pay whatever amount I ask for in return. This is a common practice that is being followed for a very long time.
In your case, I would suggest you to lookup the owner of the domain name through various lookup directories and send the owner an email/phone call and ask for his price to transfer the domain to you. Be prepared to shell out more if the domain name is high on demand. Also, don't forget to negotiate a little bit.
Let me know in case you need assistance looking up the details of the owner.
