Why not use a document preparation service?

Document preparation services are not lawyers.  It is unlawful for such services to provide legal advice.  If you want legal advice, you should hire an attorney.  If you want trademark legal advice, you should hire a trademark attorney (most attorneys have specific focuses, just like doctors).

Despite the recent commoditization of many areas of law, and trademark law in particular, trademark law is not a one-size-fits-all process.  Numerous variables determine the time and cost of an application and there are several nuances that can trip up an unwary applicant. Remember, a federal trademark registration evidences your brand ownership.  Errors in the registration can cause heartache down the road, especially in the event of a third party dispute.
