Do I need to buy a license or rights or request copyright permission for the terms, definitions, and codes of the Omaha System in order to use them?
No. The terms, definitions, and codes of the Omaha System have existed in the public domain (open source) since 1975, and, therefore, are not held under copyright. The complete terms, definitions, and codes are presented in Appendix A and Appendix E of the current book; they may be used by anyone without permission and without a licensing fee from Health Connections Press or the developers. However, the terms and structure must be used as described in the 2005 book, and referenced (ie 2005 book or Web site). When purchasing software, customers pay companies for their costs related to software development, maintenance/support, and related business expenses, but customers are not charged for the Omaha System per se.
