Pros
Will hire people who can do the work, even if they don't have all the qualifications. Graduated from law school but have yet to take the patent bar? No problem. Patent agent with no experience? No problem.
Cons
Horrible atmosphere. Low pay. A sweat shop. No training. The legal assistants are always spying and reporting on everything that the attorneys are doing. Went to a fellow attorney's office, closed the door, and vented for a few minutes? That will be reported. The legal assistants are molly coddled and encouraged to complain about the most trivial and smallest things. It was unbelievable some of the complaints I heard.
