Domain trademark (Score 1)

I registered the domain fashionisland.com back in 1997. A few weeks later I received calls from people claiming to represent Irvine Co in California which owns the huge shopping mall in Newport Beach california called "Fashion Island, Newport Beach". These phone calls attemped to persuade me to give up the domain or be prepared for a lawsuit. Trademark documents for Irvine Co. at the time(1997) i registered the domain included only the term "Fashion Island, Newport Beach" Well it seems in the past six months they have reapplied for a trademark of "Fashion Island" making their next objective apparent. To wrestle the domain from me. In the meantime I have been held hostage by threat from their lawyers on retainer about putting any type of ecommerce site here. Would love to hear any thoughts as to the way people think this one will go down in the long run.
