1 case as defendant.
Kerr Machine Co, also known as Kerr Pumps, is a privately held American manufacturing company headquartered in Sulphur, Oklahoma. Founded in 1946, the company employs approximately 135 to 160 individuals and has an estimated annual revenue in the range of $25 million to $62.1 million.
Kerr Machine Co specializes in the manufacturing of high-pressure piston and plunger pumps primarily for oilfield and industrial applications. Their product lines include well service pumps utilized in hydraulic fracturing, coiled tubing operations, reverse units, and cementing processes. The company emphasizes the durability of its fluid ends and also produces a full line of high-pressure flow line equipment through its FlowValve brand. All parts are manufactured in the United States.
In terms of patent litigation, Kerr Machine Co has a posture as a defendant in its single tracked case. The company is involved in one proceeding before the Patent Trial and Appeal Board (PTAB) of the United States Patent and Trademark Office. This indicates that a patent owned by Kerr Machine Co is being challenged for its validity.
The notable tracked case is Unified Patents v. Kerr Machine Co. Unified Patents, the plaintiff in this PTAB action, is an organization that challenges the validity of patents, often those asserted by non-practicing entities (NPEs), through inter partes review (IPR) proceedings. While Kerr Machine Co is an operating company, the challenge from Unified Patents suggests their patent(s) may have been asserted or implicated in a manner that prompted the IPR filing.
Unified Patents, acting as a petitioner, filed a Post-Grant Review (PGR) challenging the validity of US patent 12152582, currently assigned to Kerr Machine Co. The case is instituted and ongoing before the PTAB.
