EBI Patent Data Resources Patent Nucleotide Sequences

Patent Nucleotide Sequences

The patent nucleotides are the sequences of the entire patent data class (PAT) in EMBL-Bank. The database consists of different data classes. The PAT class is the data class containing patent nucleotides. The data is made available as part of the EMBL-Bank release which is updated quarterly.

Data Search and Query

To search sequences against the patent nucleotides, the user can use similarity & homology search tools. Please remember to choose the database you require from the database list before running the search. For text query, the user can use SRS and EB-eye.
