In reference to the patent: US20050088024 good afternoon,
I am a student of the master course integrated in mechanical engineering at the University of Minho and I am completing my final project, which has as its theme the development and design of a vertical and ergonomic chair.
From the research that I have been developing, it is necessary to place anti-sealing systems on the chair, so that the user does not slip during the change of position.
This patent idealizes what I need for the backrest system. How can I use this kind of mechanism without copying this mechanism? What differences does it have to have in order not to infringe the patent law? As I verify other patents that are based on this patent, I would like to see how it works.
