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, 2017
did
not
indicate an impairment of goodwill. During the
six
months ended
March 31, 2018,
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
20
years. As of
March 31, 2018,
the Company has
12
patents granted and multiple pending applications both inside and outside the United States.
