Methods for Assignee Normalization. Normalization is the process of efficiently organizing data in to eliminate redundancies.
In patent analysis, Assignee Normalization is a process of preparing clean and accurate Assignee names from the raw data that exists on the published record. When assignees are not present or organized properly, the accuracy of the analysis is greatly hampered and the results cannot be relied upon. Let’s summarize the different challenges users face with respect to Assignees when working with patent data. These are: Unknown Assignees where there isn’t a Assignee name in the publicationUnclean Assignee Names (Misspelt or subsidiaries with different company endings)Mergers and Acquisitions of companies Multiple Assignees (or Inventor names appearing in the Assignee field) The methods used to tackle each of the above challenges are different and there isn’t one size fits all approach possible.
