Find Pending Patents That May Be Issued to a Company?
TOPIC:In this example, you want to find patents that have been applied for by the toymaker Mattel in the U.S., but have not yet been published or granted.
Derwent World Patents Index® (File 351) uses a four-letter assignee code, along with the prefix CK= or PA=. The assignee code retrieves parent and subsidiary records for companies having fifty or more patents. Some codes contain I (assigned to individuals) or N (non-unique code). Using these codes may retrieve false hits. U.S. Patents Fulltext (Files 654, 652) and CLAIMS®/U.S. Patents (File 340) assign a numeric code and the prefix PA=. Codes will retrieve all patents assigned to a named company only (e.g., pa=53126).
