Note 8.  Goodwill and Patents

The Company analyzes its goodwill for impairment annually or at an interim period when events occur or changes in circumstances indicate potential impairment.  The result of the analysis performed in the fourth quarter ended September 30, 2014 did not indicate an impairment of goodwill.  During the six months ended March 31, 2015, there were no triggering events that indicate potential impairment exists.

The Company capitalizes legal costs incurred to obtain patents.  Once accepted by either the U.S. Patent Office or the equivalent office of a foreign country, these legal costs are amortized using the straight-line method over the remaining estimated lives, not exceeding 17 years.  As of March 31, 2015, the Company has four patents granted in the United States and four pending applications pending inside and outside the United States.
