Read the claims. The claims make up the legal basis of a utility patent, the abstract and descriptions don't have any weight to them.
From claim 1: "an extraction chamber comprising a top portion and a bottom portion, containing an oil-bearing substance, and configured for receiving a solvent and facilitating a low-temperature vacuum boil of the solvent within the extraction chamber"
Unless any extraction companies are boiling solvent under vacuum in their extraction chamber they have nothing to worry about.
