I own a engineering company in which I design products to serve as a proof of concept for companies to use to gauge commercial interest and funding. I also design products that may either in the exact same design, or similar are manufactured by the company, and sold commercially. I never manufacture or sell end products
I typically work on products that have little to no risk of injury, but recently have changed to more "dangerous" products. Such products have lithium batteries, high voltage systems, ect..
In either of the cases I described (me doing initial prototype, or design to be manufactured) am I/my company held liable for damages caused by my designs?
If so, will having the client (their company) sign a release of liability form help protect myself? Considering I don't manufacture, market, sell, repair, ect the product.
