Could your work or other information or results be useful to someone else if they ever got hold of it? Could any of your work be potentially patentable or registrable as a design? If the answer to any of these questions is yes, it is important to consider confidentiality. Confidentiality is the best way to protect your Know-How.
The ‘someone else’ could be an individual from a company. They could be a member of another research group or someone from another institution. They could even be a friend or relative. The information may include results, chemical formulae, information from laboratory notebooks, experimental procedures or techniques, information concerning the handling or programming of equipment or source code. It may be personal or commercially sensitive information such as customer lists or results from market research. These are just a few examples.
