The cost of the patent process is actually a minor part of the costs of bringing a new product to market. Development, prototypes, testing, test marketing and distribution are significantly greater costs. Contact the Missouri State University, (MSU) Small Business Development Center (SBDC) at 417-836-5685 www.sbdc.missouristate.edu if you are in the Springfield, MO area or the Small Business Development Center nearest you. Assistance is also available at the Missouri Enterprise Business Assistance Center, www.missourienterprise.org. Either organization can provide you with valuable assistance on business plan development. You may also wish to participate in the WIN program to get an independent review of the marketability of your product. The MSU SBDC can help you with that as well. Many inventors seek financial help from local Venture Capitalists, the Small Business Administration or private institutions. You will want to enter into secrecy/confidentiality agreements with any individual or private institution before you disclose your invention to them.
