It may seem obvious, but advise your client to record the data collected during the audit in an inventory or asset register. Ideally, this record is kept electronically to enable ready access and updating. If a database format is used, multiple report formats can be generated. Once your client has identified its intellectual property, common sense dictates they should protect it. They protect and insure against loss of physical assets.
Intellectual property deserves no lesser treatment.
Effective legal protection is the best way for your clients to stake their claim to ownership. Assist them to utilise the full extent of Australia's intellectual property laws. Registered rights cost money and can take time. Advise your client to consider seeking protection in all potential major manufacturing, distribution and retail markets, not just in Australia. There are various methodologies for the valuation of intellectual property ranging from cost-based methods to capitalisation of notional or actual royalty licensing streams.
