I am doing a publication using a specific optical instrument protected by different patents. To see how it works I opened it and I have redrawn the arrangement of the optical components. Am I allow to publish my drawing for explaining the physical principle behind the measurements I have performed during my research?
It's not a reverse engineered designed, there are no specific distances between the components or other relevant details for the construction. I am showing an abstraction but more or less the parts and the arrangement is the same as the real one.
The drwaings, are of course mine. I would like to publish on my PhD thesis in Italy, but in general I am interested on any pubblication.
