COMMITMENTS AND CONTINGENCIES	COMMITMENTS AND CONTINGENCIES Patent Infringement Matters. On December 15, 2014, our subsidiary, Quest Integrity Group, LLC (“Quest Integrity”), filed three patent infringement lawsuits against three different defendants, two of the lawsuits were filed in the U.S. District of Delaware (the “Delaware Cases”) and one in the U.S. District of Western Washington (the “Washington Case”). Quest Integrity alleges that the three defendants infringe Quest Integrity’s patent, entitled “2D and 3D Display System and Method for Furnace Tube Inspection.” This Quest Integrity patent generally teaches a system and method for displaying inspection data collected during the inspection of furnace tubes in petroleum and petro-chemical refineries. The subject patent litigation is specific to the visual display of the collected data and does not relate to the underlying advanced inspection technology. In these lawsuits Quest Integrity is seeking injunctive relief, as well as monetary damages. Defendants denied they infringe any valid claim of Quest Integrity’s patent, and asserted declaratory judgment counterclaims that the patent at issue is invalid and/or unenforceable, and not infringed. In June 2015, the U.S. District of Delaware denied Quest Integrity’s motions for preliminary injunctive relief in the Delaware Cases (that is, our request that the defendants stop using Quest Integrity’s patented systems and methods during the pendency of the actions). In March 2017, the judge in the Delaware Cases granted summary judgment against Quest Integrity, finding certain patent claims of the asserted patent invalid. In late 2018 and early 2019, Quest Integrity settled with the defendant in the Washington Case and settled with one of the two defendants in the Delaware Cases. Quest Integrity also appealed the ruling in the Delaware Case with the remaining defendant. In May 2019, the Court of Appeals for the Federal Circuit issued an opinion reversing and remanding the decisions of invalidity on certain claims and reversing other material aspects of the U.S. District Court of Delaware’s findings. The U.S. District Court ordered mediation between Quest Integrity and the remaining defendant on February 28, 2020, and scheduled the remanded trial for the fourth quarter of 2020. In mediation, Quest Integrity and the remaining defendant agreed on the framework for a full and final settlement of all claims. As a result of the mediation in February 2020, we recorded a loss of $1.3 million and have adjusted our 2019 consolidated financial statements to reflect the impact of this event. Execution of a final settlement agreement and entry of an order of dismissal of the case is expected in the second quarter of 2020. We are involved in various other lawsuits and are subject to various claims and proceedings encountered in the normal conduct of business. In our opinion, any uninsured losses that might arise from these lawsuits and proceedings will not have a materially adverse effect on our consolidated financial statements. We establish a liability for loss contingencies, when information available to us indicates that it is probable that a liability has been incurred and the amount of loss can be reasonably estimated.
