Filing a third-party IPR disclosure

[Stewart Bryant <stewart.bryant@xxxxxxxxx>]

I need to file a third partly IPR disclosure on work that I did with a 
previous employer.

I went to the third party disclosure page and input the information that 
I knew. I only know the Company, two of the inventors and the subject. I 
do not know the patent number or date. The form used to accept best 
effort disclosures like this, but now will not permit submission without 
the patent number and filing date.

The form implies that failure to provide the patent number and date 
result in a non-conformant submission.

What is the correct method of disclosing IPR when you only have partial 
information?
