The U.S. Court of Appeals for the Federal Circuit (CAFC) today issued a precedential decision reversing a district court’s finding that an error in Canatex Completion Solutions, Inc.’s patent claims rendered the claims indefinite. Canatex’s U.S. Patent No. 10,794,122, titled “Releasable Connection for a Downhole Tool String,” contains a phrase that reads “the connection profile of the second part,” which appears in all the independent claims, and should have read “the connection profile of the first part,” according to Canatex. The error also appears in the Abstract and twice in the written description.
