The pending matters require current docket attention, while the allowance rate and office-action average describe resolved activity. The average indicates that allowance has involved repeated examination interactions, but neither historical measure predicts a particular outcome. Practitioners should tailor strategy to the biological or pharmaceutical claim limitations, cited art, and disclosure available in each application.
