Covered Business Method (CBM) petitions are limited to patents relating to “a financial product or service.” CBM petitions are generally favored by defendants over Inter Partes Review (IPR) petitions by allowing a defendant to challenge the patent-eligibility of the claimed invention. And while some believe the PTAB has broadly construed the inventions falling under the umbrella of “financial product or service,” the PTAB recently held a website labeling patent to be ineligible for CBM review.
