Databases of molecular data on the NCBI FTP site include such examples as
nucleotide sequences (GenBank), protein sequences, macromolecular structures,
molecular variation, gene expression, and mapping data. They are designed to
provide and encourage access within the scientific community to sources of
current and comprehensive information. Therefore, NCBI itself places no
restrictions on the use or distribution of the data contained therein. However,
some submitters of the original data may claim patent, copyright, or other
intellectual property rights in all or a portion of the data they have submitted.
NCBI is not in a position to assess the validity of such claims and, therefore,
cannot provide comment or unrestricted permission concerning the use, copying,
