I am going to give my final viva voce for my PhD. My supervisor is asking me to sign an IPR declaration letter before leaving the institute. In the letter it is mentioned that my name shall not be included in any IP filing/publication as an inventor, even though those can be results of my invention or research.
My question is, Can someone exclude me from becoming inventor of my own research output like this? Even if I have to sign it now under indirect pressure (as I have to get my PhD), may I challenge the contents of the declaration in future?
