Powerful. Resilient. Ever-evolving. These characteristics of the Patent Trial and Appeal Board (PTAB) were on full display in 2019. This past year the PTAB received more than 1,300 inter partes review (IPR), post grant review (PGR), and covered business method review (CBM) petitions, issued a similar number of institution decisions, and rendered nearly 500 final written decisions. These petitions and decisions involved more than 1,800 unique patents – most of which are involved in co-pending district court litigation with billions of dollars on the line.
