I have found a soluion.
I write with gnostice tool PDFToolkit VLC with Delphi to each PDF a pseudo doi (it stands in the subject line) and in the refs mysql database also this pseudo doi by my delphi (MyDAC MYSQL connection) programm.
No I can import the hole folder with the Patents
(added with f.e doi:10.1186/s12986-015-0010-9-’+<patentnummer>;
in my unit.pas: gtPDFDocument1.DocInfo.subject := ‘2015, :. doi:10.1186/s12986-015-0010-9-’+<patentnummer>;
)
to the endnote database via the Endnote IDE in a normal way. It works fine.
TReuters should consider to import Patents in a more easier way. F.e by identifieing the filename als pat nummber. But as this is not done till now, my above advice could be useful.
