Cabello Hall Zinda Secures Institution Decisions Against Three SPM Oil & Gas Patents

We are pleased to announce that the Patent Trial and Appeals Board has granted institution of all petitions we filed on behalf of Kerr Machine Co. Specifically, we filed a petition for post-grant review (PGR2022-00033) and two petitions for inter partes (IPR2022-00881/00882) review challenging three patents asserted by SPM Oil & Gas Inc. The Board found that Kerr carried its burden of showing that it is likely to prevail with respect to all three petitions and accordingly instituted trial in each proceeding. The institution decisions are available below:
