Ask HN: Selling a brand

I'm in a situation some HN readers may have been through before. Last year I effectively shut down my startup - after putting in several years, it hadn't lifted off, and I decided to move on. During that time, I accumulated different forms of IP around the company name: not just the domain name, but the US trademark, all popular toplevel domains and other variants (e.g. close misspellings), social media accounts, etc.

I'm not sure what to call this collectively, so I'm calling it a "brand".

I may start another company in the future that could use this name, but since I don't have immediate plans to do so, I'm wondering how these could be sold. Certainly the complete package has much higher value, to the right buyer, than the domain name alone.

Have you been involved in the sale of such a thing before? If so, how did you go about it? Did you use a broker? (If so, can you recommend a good specific one?)

Or did you go with cold-calling specific prospects? If so, how did you identify them? Did you contact individual companies? One thought I had was to contact VCs who might be funding in a related space.

Full details, since I know someone will ask: http://mobilewebup.com/
