Espacenet claim tree algorithm

Post by VATA » Mon Dec 21, 2020 12:34 pm

Espacenet offers the option to visualize the claim tree of a patent. Which algorithm does it use to produce the tree? Is it somewhere available for the public or can you please bring me into contact with the person responsible? I want to use the algorithm for my master thesis. thank you

Dear Andrèe,

First of all - thanks for sharing the basics on how the claim-tree algorithm works.
Still, the algorithm seems not to work if instead of "Anspruch" the claims are worded as "Patentanspruch". For example, consider the following patent document with regard to their german set of claims: EP1538277B1.

Maybe this could be added as additional rule for the parser?

Kind regards,
Jsfiddler
