SUMMARY
This document https://www.uspto.gov/sites/default/files/documents/aia0014.pdf fails to display in Okular because it is tailored for Adobe Reader.

In fact PDF documents are just a collections of vector graphics and all of them should be able to be opened in Okular.

Also "P" stands for portable.

I suggest to add a feature that the user would be able to overcome user agent limitation and open the document designed for a specific viewer anyway.

Sorry, but your request seems unrealistic to me.

PDF means portable, yes.
But that does not prevent authors from intentionally creating bad documents.

The content of this document is “Please wait ...”.
It is hard to guess what Adobe Reader would show instead.
In this particular case it may be enough to implement XFA.
But in other cases Okular would need to guess how Adobe Reader’s implementation of XFA would behave.
That would be like magic.
