Good IP maintenance pays for itself. In the Profit and Loss Account of companies, ‘maintenance costs’ are always mentioned. Things like the building, the machine or fleet and ICT require constant maintenance. They are company assets with which the company delivers its added value in the market. They should be and remain in optimum condition just like the employees. Experience has taught us that the assets that are not tangible / visible, such as intellectual property rights (IP), are only partially maintained.
