DDBJ Center provides some services to search and to browse sequence data that are included in patent applications.
The nucleotide sequence data included in patent applications that are collected and processed by the Japan Patent Office (JPO) and the Korean Intellectual Property Office (KIPO)* are imported into the International Nucleotide Sequence Database Collaboration (INSD) via DDBJ and are made available to the public.
Similarly, the nucleotide sequence data collected by the European Patent Office (EPO) and the United States Patent and Trademark Office (USPTO) are imported into INSD via EMBL-Bank/ENA and GenBank, respectively.
* The procedure to import KIPO sequence data into INSD through DDBJ was started from February 2008.
You can distinguish the nucleotide sequence data included in patent applications by prefix of accession numbers.
The nucleotide sequence data included in patent applications can be searched or browsed from the following DDBJ services. Please note that these services do not differentiate data from JPO, KIPO, EPO, USPTO as reference datasets.
The amino acid sequence data included in patent applications that are collected and processed by JPO and KIPO are made available through DDBJ.
Similarly, the amino acid sequence data collected by EPO and USPTO are made available by EBI and NCBI, respectively.
The amino acid sequence data included in patent applications can be searched and browsed from the following services at DDBJ:
