I'm in sixth year in a graduate program where I'm expected to collaborate and share my work (as many of us are in PhD programs). There have been a couple of occasions now when my research (manuscript in preparation) has been used by my younger peers (either to inspire their research or actually used my research within their research) with no acknowledgement or credit given to my work. I don't know if I should take this to my advisor. Second, it gets me thinking. As graduate students, who has ownership of our ideas? What if we're working under our mentor's funding? And moreover, how do you protect your work when it's not published yet?
Any wisdom would be greatly appreciated.
