I have tried searching for succinct answers to the following but that which I have found is ambiguous and murky. I am after black and white answers as many of us have probably come across this tricky area in research.
I've found a publicly available research paper in which the authors create and test a style of medical electrode. The style has been researched before by other universities around the world as well which focuses on replicating the van der Waals forces that gecko's feet utilise. They detail how they fabricated the electrode throughout the article. If I were to fabricate the electrode myself would this be infringement of either the author's or university of publication's IP if I were to:
i) fabricate for my own private personal testing of the device to see if I can better it in someway or alter it to meet my specific use requirements and not sell (private use)
ii) As per i) however choose to now sell this altered or bettered version of the device (commercialize once device is altered)
iii) fabricate unaltered the device in order to publicly sell the item (commercialize on the unaltered device)
