Weird Assignee Organizations

There are weird assignees in the underlying uspto data. The patent numbers are links to the uspto pages for the associated patents. This page is sending in a get request to the /assignees endpoint with the following parameters:

q={"_contains":{"assignee_organization":"grave over"}}

In English that's asking for assignees that contain the phrase Grave Over, specifying a list of fields to return please, and if it's not too much bother could the assignees come back sorted by assignee_organization?
