Excalibre Oil Tools Ltd. v. Advantage Products Inc. concerns the validity and infringement of three Canadian patents. Justice Manson held that the three patents (Nos. 2,264,467, 2,373,734 and 2,386,026) asserted by API were either invalid or not infringed by Excalibre's product.

The technology at issue relates to torque anchors for oil pumps. Sufficient pressure is required to extract the oil from the earth, which can be generated using a subterranean pump. This pump forces the oil to the surface. The use of the pump, however, generates torque. This can cause the connections on the production tubing (through which the oil is brought to the surface) to become unthreaded. Accordingly, torque anchors (also known as anti-rotation devices or "no-turn" tools) are employed to prevent rotation and the unthreading of the production tubing.
