At the time we could only get the .net of the domain we wanted. The .com was being used in a completely different field. Last year it came up in a domain auction but the bidding went higher than I was willing to pay so I missed out.
Now someone is getting ready to launch a new website on the .com doing exactly the same thing as what our system does.
My question is can or should I do anything about it, do I have any rights with prior use of the name etc (product name is same as domain etc)?
