IPH (ISX:IPH) is continuing to work with external cyber security and forensic IT advisors to respond to and investigate a cyber incident that was announced on March 16th.

The patent and trademark firm says the incident was limited to document management and practice management systems of IPH head office and two IPH member firms in Australia.

New network infrastructure has been established with security further enhanced to protect the IPH network, and the two affected IPH member firms have resumed normal operating procedures on the new systems and all other IPH member firms are operating as normal.

The investigation is expected to continue for a number of weeks and IPH will update the market as appropriate.
