A dynamic Expert System (DES) for Intellectual Property (IP) Management in Corporate bodies has been designed and implemented using Electronic Development Institute (ELDI) Awka, Anambra, Nigeria as case study. This is a system that will capture the present best practice for every shade of work done in a company which is what represents a company on paper, if a staff of the company resigns, dies or goes away and a new personnel is hired and trained with those best practices, they will represent the company well because the best practices represent all that is done in a company in the best possible way. A dynamic expert system (DES) is dynamically kept up to date as more knowledge is gained. This is a useful means of managing the Intellectual Property that drives an organization forward so that the Knowledge Repository can be enhanced with new industry best practices as more knowledge is gained and edited to remove obsolete knowledge. A quarterly elicitation process is done in a continuous in-house search for new IPs. The new IP claims are validated through peer review and successful ones are used to update the DES knowledge Repository. This makes the operational IP of the corporate body grow dynamically with industry best practices. The software used for the Dynamic Expert System (DES) inference Engine is written in Java Programming Language. DES was validated by comparism with other related projects and it was found that Des performed better than others in five (5) of the ten (10) areas of comparism used.
