Direct links to older patents no longer working
Posted: Thu Oct 08, 2020 1:46 am
Hello,
I have a patent index which links directly to historic espacenet patent entries, but the links no longer work for older patents.
For example, I could link to Hayward's 1871 GB patent #2014 "Pavement Lights" with the URL
<http://v3.espacenet.com/textdoc?IDX=GB18712014>
but this no longer works ("not found").
This still works for more recent patents such as Pennycuick's 1897 GB patent #27955 "Improvements in Vault Lights".
What has changed and how do I link to the older patent entries now?
Thank you.
