Concurrent use information. The purpose of this Service Mark registration is to add to my Registered Service Mark Reg. No. 5,316,953. The original intent of this Service Mark was to perform research in the field of education. That research has now led to the applied use of that research, thereby placing the curriculum into practice in pre-K-12 classroom instruction. Therefore, I would like the addition of the classification of goods and services in addition to - not to replace Term ID 041-1313 Research in the field of education (as this research will continue) - but to include the addition of Term ID 041-2038 Education services, namely, providing pre-kindergarten through 12th grade (pre-K-12) classroom instruction.
