 The ensuing lawsuit resulted in the loss of the patent for Acoustic Research, a decision which Villchur chose not to appeal.In an interview about the case, Villchur says that he knew the judge's decision to void the patent was incorrect, but that he felt he had better things to do than to spend his life in litigation.He cited the example of Edwin Howard Armstrong, the inventor of FM radio, whose patent was rendered unprofitable through the actions of RCA.
