1. Queen Electronics, a retailer of video equipment, sold two DVRs to Larson, a psychologist, for use in her professional practice, which was located in her home. The sale to Dr. Larson was made on credit. Queen retained a security interest in the DVRs sold, but did not file a financing statement. Wilson, another creditor of Dr. Larson, has asserted that his lien on the two DVRs is superior to Queens security interest. Is Wilson correct under the law? State your reasons and the legal support for your reasoning. (Remember to classify the DVRs as collateral in the hands of Queen and Wilson as you prepare your answer.)
