Is it possible to \print(the whole)bibliography of one author and then further in the text to \print(the whole)bibliography of another author, and then a third author, etc. The entries that have at the same time the first and the second author should be printed once for each author. The authors might be cited at any rank in the author list. Different reference types (article, inproceedings, patent, etc.) are present in the bib file.
Here is a minimal example borrowed and adapted from here

filterper\printbibliographycall. If that is the case you can avoid the problem by combining the definition of the two filtersnewandfilternamesinto one. – moewe Mar 01 '21 at 12:53
