When I submit an ajax url that has only a hashtag in its url (f.e. https://app.patentinspiration.com/#patent/EP2636723A1) then your crawler doesn’t recognize the fragment meta tag that is present on my webpage. I thought that when the fragment meta tag is present on an ajax url that then the bot also knows that it can request a static version through the escaped_fragment parameter (f.e. https://app.patentinspiration.com/?escaped_fragment=patent/EP2636723A1).
Does your bot support the fragment meta tag?
