embargoes on the distribution of sample preparation knowledge not publicly reported. It is usual for the measurement scientist to perform only the measurements proposed formally to the network grower, and only within the measurement range formally specified or reasonably extended. Specifically, it will not be the role of the measurement scientist to ship network-grown samples to another measurer, that is, to act as a broker, without consent of the grower.
Roles and responsibilities of the grower. The grower will not distribute samples of the same compound to different measurers for the same measurement without notifying the measurers. The grower will keep the measurement collaborator informed of all information obtained regarding materials of common, present interest that significantly impact the conduct or interpretation of measurements.
Custodianship of samples (including physical protection and storage of samples). Scientists responsible for the synthesis of new materials and the growth of crystals in the network would ultimately be responsible for the custodianship of the samples they create. Recognizing that samples are rarely sent back to the grower after a measurement is completed, it is expected that the measurer exercises reasonable care in storing samples.
Intellectual ownership. Whether research is motivated by the grower or the user, the grower creates the value of the crystal. For grower-motivated research, it is understood that all rights of priority normally accorded to federally funded synthesis research would be held by network-supported growers. These rights might include the selection of collaborators who would perform some of the first sample measurements, or it might require collaboration for the initial measurements. The goal is to ensure that the grower retains full intellectual ownership of materials discovery and initial properties. Simultaneously, the network would strive to increase access to network-grown samples. Achieving these two goals might require providing a dormancy period—perhaps 6 to 12 months after the first publication on a particular sample growth experiment—when the grower would possess right of first refusal for a sample measurement proposal. After this period, samples would become subject to the normal network proposal procedures.
Intellectual property rights. Details of intellectual property ownership and intellectual property rights would be developed by the network’s external scientific advisory board in collaboration with the federal funding agencies and the network administrator.
Attribution. The guiding principle regarding the attribution of credit for research accomplishments would be that of collaboration. Specifically, sample provisioning by the network would be viewed as a collaborative activity, and the network scientists would be afforded credit and coauthorship
