I entirely came up with a novel idea. I did all of the research indepently. Both my supervisors want to patent the idea now. It seems that I'm getting a smaller stake in the patent according to the filing papers (they didn't talk to me about this). I own 25%, they own 37.5% each.
I can't help to feel like I'm being swindled. The university is paying for patent costs. But, I came up with the idea entirely on my own. Also, this isn't related to my main research project. I just worked on it on the side - so they didn't have much contributions towards the overall idea [actually one of them had literally ZERO contribution to the original idea and just happened to be my supervisor at the time].
Should I say something or is this common?
