A patent for a database of brainwave patterns for people thinking about specific things, that brainwave patterns can be compared to in order to identify thoughts

A catalog of recorded emotions by brainwave state, and their related facial expressions, potentially indicating a work on a digital map of emotions (in the form of an ai model). This could later be used to figure out which of a wide array of variables can later be adjusted or controlled to induce the specific emotions. It could also be used to assess people out of reach by using cameras watching facial expression.

A patent for a way of analysing brainwave responses to specific visual surveys and target people in a crowd for brainwave analysis

A way of analysing responses to pictures, diagrams etc. using what looks like and eeg (described as a brain wave detector), they note the fact it can be used on groups of multiple people to spot consistent changes in emotions and to read individuals brainwaves in a crowd, they claim people were tested against different intensities of certain types of picture.
