TrademarkNow provides a comprehensive web-based system for trademark management. At its core is an artificial intelligence model of trademark similarity (likelihood of confusion) based on the authors doctoral research in computational legal theory on computational modelling of vagueness and uncertainty in law at the University of Helsinki, currently at its final stages. The system utilizes a carefully designed blend of both rule-based and statistical techniques to deliver results while managing real-world complexity in the trademark domain. After all, in principle a trademark information system has to be able to represent the entire world of commerce in all existing and fantasy languages in one way or another.
