What types of cases are considered “contested cases” before the PTAB?

According to MPEP 1449, contested cases before the Patent Trial and Appeal Board (PTAB) include several types of proceedings:

“A contested case includes a derivation proceeding, an inter partes review, a post-grant review, and a covered business method review.”

These proceedings are part of the post-grant patent review process and can be initiated to challenge the validity of a patent after it has been granted. Each type of proceeding has specific requirements and timelines as defined in patent law and USPTO regulations.
