Around a decade ago the company I was working for launched a new startup. It was owned by my company and I was tasked to work as a consultant helping them set up their IT infrastructure 50% of my time. As they were using completely different setups I was given an additional laptop. The startup was always its own legal entity so the laptop was owned by them. After a couple of months my work was done but they asked me to keep my laptop in case they have some follow up questions.
Roughly 2 years later the startup was carved out of the company as a completely standalone entity (with a majority share from the company I was working for). Unfortunately a year later it became insolvent and was liquidated eventually (long time ago completed). All this time I was still having the laptop I was given to work with.
Recently I was searching for something in my cellar and I found that laptop. I was curious, what is the ownership situation of this laptop now? I have no plans to actually find someone to give it back to, but legally speaking, what would be my obligation in this scenario?
My jurisdiction (Switzerland) does not have a lot of people on here, so I am open to any countries, I am most interested in Western European laws, but also what would apply for example in the US.
