Hello business forumites, I have a question about: 1. The protection of intellectual property when dealing with business partners, in this case, manufacturers. 2. The insurance against unsatisfactory results from said manufacturer. I will be commissioning a unit to be manufactured according to a design. Is an NDA or confidentiality agreement sufficient to protect that design regarding issue 1? Would it be wise to also file a design right, or would that be superfluous considering the former point? Could a contract of supply be utilised to serve issue 2? Thanks in advance answerers!
