Thanks for hosting the event; I hadn't been to Thoa's before. It was a nice time with nice, fun, intersting people.

Its a great idea, once you think of a name, is to ensure that--

1. You can get the domain name that matches the business or product name,

2. No one has a trademark on an identical or very similar name for an identical or very similar business or product, and

3. No one is using the name for an identical or similar business of product.

A lot of companies will have an attorney do a trademark clearance review (or registerability opinion), but a low-cost alternative would be to check the trademark registry at the USPTO.gov, the trade names database at Washington's Department of Licensing, and do some web searches on similar names and products.

Also, the secretary of state has promised to make Washington State registered trademarks available to search online in the very near future. (Currently, you have to pay the trademark department at the Secretary of State's office to perform a check for you or hire someone who has access to their database.)
