Patent citations ESPACENET vs. Fulltext
Posted: Wed Mar 01, 2017 2:26 pm
Hello Espacenet Team
I was wondering why in some cases the number of patent citations (backward) that shows ESPACENET is different to the ones in the full text document.
For example: patent EP2604284 shows in CITED DOCUMENTS no NPL cited by the applicant, whereas in the EP fulltext on the last page a reference list shows 3 NPL citations.
Reg. to this matter:
how are the applicant citations in EP patents identified? Automatically generated by text-mining in the full text (which can lead to errors by no identification of references)?
Best regards
