There are few things worse than receiving an email that a Notice of Opposition was filed against your client's trademark application. You waited patiently for 3-4 months for the Examiner's review, resolved the Office Actions, and all that was (supposed to be!) left was the 30-day publication period...then boom. Everything is stalled. Or maybe your client is the one who notices an application that is likely to cause confusion. Would you know what to do? What are the next steps after the initial filings? How do you handle discovery?
