The STN Standard Template - STN International

Update requirements of patent databases
• Patent records are often dynamic
– Sophisticated data structure
• Different types of data
• Various indexing + classification systems
– Updated, corrected and amended frequently in
different parts of the record, e.g., indexing vs.
patent family additions
– Relevant parts which are updated get distinct
update codes
• For a SDI, it often matters which part of the
document is being updated
