We offer free, unrestricted access to dedicated patent sequence databases that contain valuable information about patent family data, patent equivalents and earliest priority dates. These databases also offer access to full-text patent documents. Our non-redundant patent sequence databases help you search efficiently and return de-duplicated results, saving valuable time and effort. Patent nucleotide and protein sequences are contributed by the European Patent Office (EPO), US Patent and Trademark Office, and the Japanese (JPO) and Korean (KIPO) patent offices, including World Intellectual Property Organization (WIPO)-approved patents from these offices. Further agreements with patent offices from Brazil, Canada, China and Mexico have been achieved or are in progress.
