Intellectual property expert witnesses
Expert class library · 8 classes
The damages and technical experts in patent, trademark, copyright and trade-secret cases: reasonable royalties, lost profits, apportionment, surveys, infringement and invalidity.
Each class is defined by role and method, never by a person or a firm. Open one for what its testimony turns on, how it is attacked, and the rulings, each summarised from the opinion and linked to it.
