Flawed and Insignificant Research Advertisements based on flawed and insignificant research are defined under section 43(a) of the Lanham Act as "representations found to be unsupported by accepted authority or research or which are contradicted by prevailing authority or research." These advertisements are false on their face.
Alpo Pet Foods v. Ralston Purina Co., 913 F.2d 958 (D.C. Cir. 1990), shows how basing advertising claims on statistically insignificant test results provides sufficient grounds for a false advertising claim. In this case, the Ralston Purina Company claimed that its dog food was beneficial for dogs with canine hip dysplasia, demonstrating the claims with studies and tests. Alpo Pet Foods brought a claim of false advertising against Purina, saying that the test results could not support the claims made in the advertisements. Upon looking at the evidence and the way the tests were conducted by Purina, the court ruled not only that the test results were insignificant but also that the methods used to conduct the tests were inadequate and the results could therefore not support Purina's claims.
