New STN:


KRFULL covers the full text of published patent applications, granted patents and utility models in the Republic of Korea (KR). The records of the database contain bibliographic data including patent applicant, inventor, and agent, publication, application, priority, and related application data, IPC and CPC classification codes, abstract and the full text of detailed descriptions and claims. Records are available about a week after publication date with the complete content. Titles, abstracts, detailed descriptions and claims are machine translated to English. Title, abstract, detailed description, and claims as well as patent assignees, inventors and agents are displayable in Korean characters. Each database record contains all documents published for one application, displayed in order of appearance. Numeric values of 59 physical and chemical properties in about 20,000 unit variants of the base and additional units are searchable in all English full text fields. Keyterms, i.e. noun phrases of 1 to 5 words extracted from all English text fields, are provided in an extra search field. Images, mostly front page images, are included when available. Patent assignee names are standardized and normalized in extra search fields.

Online thesauri are available in the /IPC and /CPC. Additionally, legal status data, patent and non-patent citations, and family display formats from the INPADOCDB database are available. Automatic current awareness searches (SDIs) may be run weekly (default) or monthly. Some of the full text has been created by Optical Character Recognition (OCR) software. Therefore, characters may be misinterpreted, or portions of the text may be incomplete.
