Curious Case of USPTO data

We assume USPTO bibliographic data to be reliable, but in the case below, there is an ambiguity in Inventor between USPTO patft and USPTO assignment.

I have encountered many instances where assignments data is dubious. For critical information projects one must be very careful in relying on such data.

Publication number - US6525513

USPTO has done commendable job in providing data in usable format. However, analysts must be careful in blindly relying on the data provided by USPTO and other database sources.

No matter how sophisticated analytics system become, there is and will be no replacement of human intelligence.
