As a relatively new solo practitioner, I find it very helpful to be able to search file wrappers for key words when new situations crop-up with applications. For example, it's helpful to see how to complete a form I'm unfamiliar with, or what supporting documents might look like when filing a petition that I haven't had to file before. With Public-PAIR it's impossible to search for keywords...you already have to know the application number. But with The Patent Box, finding an exemplary application is just a few clicks away.
