Contingencies [Abstract]
Contingencies	(11) Contingencies Due to the nature of the Company’s business, the Company is involved, from time to time, in various routine litigation or subject to disputes or claims or actions, including those commercial in nature, regarding its business activities in the ordinary course of business. Legal costs related to these matters are expensed as incurred. Management is of the opinion that none of the claims and actions will have a material adverse impact on the Company's financial position, results of operations or cash flows. A subsidiary of the Company is involved in legal proceedings with two former employees regarding the payment of royalties for a patentable product paid for by the subsidiary and developed while they worked for the subsidiary. On April 2, 2018, the former employees and their corporation filed a lawsuit in the Harris County District Court alleging that the royalty payments they had invoiced at 25% and for which they received payments since 2010, should have been paid at a rate of 50%. In May 2019, the jury issued a verdict in favor of the plaintiffs. On October 25, 2019, the court issued a final judgment against the Company which the Company has fully secured with a supersedeas bond. The Company strongly disagrees with the verdict and believes the district court committed several legal errors that should result in a reversal or remand of the case by the Court of Appeals. Commencement of the Chapter 11 Cases automatically stayed certain proceedings and actions against the Debtors. These cases continue after the Chapter 11 Cases.
