I think markmonitor.com offers this sort of service, but I suspect it's "call us" pricing.

Note how domains like google.com, amazon.com, microsoft.com are registered with them. You can find similar services by looking in Whois records, e.g. bankofamerica.com is with www.cscprotectsbrands.com, lloyds.com is with ascio.com.
