Patent data resources at the EBI contain patent abstracts, patent chemical compounds, patent sequences and patent equivalents. Multiple sets of patent sequences are available at EBI. Patent proteins cover sequences of EPO (European Patent Office) proteins, JPO (Japan Patent Office) proteins, KIPO (Korean Intellectual Property Office) proteins and USPTO (United States Patent and Trademark Office) proteins. Patent nucleotides contain the patent class data in the EMBL-Bank. Non-redundant patent sequences consist of 2 levels databases. Level-1 non-redundant patent sequences are 100% identical over the same length; Level-2 non-redundant patent sequences are identical and belong to a same patent family (a same invention).
