Experimental research work on a similar experimental setup patented by someone else For my PhD thesis, I have conceptualised an experimental setup which is similar to an already existing patented design. Can I do research work on that setup (conceptualised by me) by simply citing that patent ? Are there other things to keep in mind ?
You should probably consult an IP lawyer. Your institution probably has someone who can help with this. Depending on what you are doing you may be using the patent idea or not (ie violating). You might be able to get a license from the patent holder. Lots of possibilities here. 

In one scenario, the patent owner may be interested in your work. 

But there is too little stated in your question and too much implied to be able to give nay definite answer.
