Canrig Drilling Technology LTD. V. Trinidad Drilling, L.P.

Representative Claim

  1. (‘956 Patent) A drilling method comprising: monitoring the rotation of a drill string with a sensor; transmitting said rotational information to a computer; controlling a motor that rotates said drill string with said computer; and oscillating said drill string between predetermined angles.
  1. (‘973 Patent) A drill string drive comprising: a motor adapted to rotate a drill string; a sensor adapted to detect a rotational position of said drill string at the surface, wherein the sensor is at the surface; and a computer receiving the rotational position from said sensor, said computer transmitting control signals to said motor, said computer programmed to control said motor to advance said drill string to a predetermined angle.

Posture:

Rule 12(C) – Motion for judgment on the pleadings.

Abstract Idea: No

“The claims in Canrig’s patents address specific challenges in directional drilling through a concrete process for controlling the rotation of the long drill strings to and between predetermined angles. The patent claims are directed to a physical apparatus and drilling process of controlled rotation by a specific amount (the predetermined angle). Such tangible, industrial processes have long been considered eligible to receive patent protection. See Diehr, 450 U.S. at 184..”

Although rotation in isolation is an abstract concept, Canrig’s patented process uses controlled rotation within predetermined angles to orient and oscillate a drill string. This eliminates the guess work, and resulting inaccuracies, inherent in the prior method of directional drilling. See, e.g., Diehr, 450 U.S. at 187 (patent eligible process for molding synthetic rubber eliminated the guess work, and resulting inaccuracies, in measuring the temperature inside the molding press and calculating when to open the press and remove the molded, cured product).
