I am working on a device which is in the prototyping stages. We may at some point decide that we have proven the concept of the device, and then we would need to sort out intellectual property. I am trying to determine who or what owns this device, and whether I would receive any part of future royalties.
I was studying X as part of my PhD thesis work. I showed X to a visiting colleague and he suggested that X could be turned into a device with a specific and useful purpose. I am a graduate student at a university. We sent a proposal to a government institution requesting funding to prototype this device. The proposal was shot down, but they did provide useful feedback regarding what they would like to see proven to verify that the device would work.
I am now working as an intern at another government institution which has good facilities and people for building devices. We are building a prototype of the device in order to test the concerns the previous government institution had. The place I am working is providing some funding for materials.
Assuming the tests go correctly, we will apply for a large grant from a 3rd government institution.
So I finally mentioned all parties, and I am would like to know who will own the intellectual property of this device (or will it be split). Will it by my school? The colleague who proposed the device? The first, second, or third government institution? My Adviser? Anyone and everyone who contributed in some part? Or finally, can I get a piece of the action myself?
All of this took place in the United States
