Evolution of the Patent Information World – Challenges of yesterday, today and tomorrow.

Over the last 18 years, the field of patent information searches has dramatically evolved. Centralized information centers have started to disappear while new internet applications targeted at end-users have emerged. At the same time, the quantity of information has increased exponentially.
