Patent No. 1,086,339 has been granted on this powder to P. J. A. Maignen of Philadelphia by the U. S. patent office on the following specification of claim made in the application: “1. A process for destroying microorganisms on living tissue, without injuring the latter ... whereby the growth of such organisms is inhibited and their substance dissolved without deleterious effect upon contiguous healthy tissue.” With brazen assurance this grant has been twisted by the unscrupulous promoters into a government endorsement of the preparation. It, of course, means nothing of the sort, as, no doubt, in accordance with legal routine the patent was granted without any investigation by the patent office to determine the effectiveness of the powder for the purpose claimed. In view of the dangerous, unwarranted and absurd claims made for Maignen Antiseptic Powder the referee recommends that it be refused recognition, and that the Council declare its agreement with views expressed in the article “Maignen Pulv.” published in The Journal, Feb. 15, 1913, p. 537, particularly the following: “The germicidal powers of strong alkalies have long been known, but the inconvenience of their application to tissues and mucous membranes has prevented their use. That they will be of service when sufficiently diluted not to irritate the tissues is improbable, for the antiseptic power of such solution is slight and the disinfectant value practically nil.” Because the Maignen Institute has twisted the granting of U. S. patent No. 1,086,339 into a quasi-endorsement of the claims made for Maignen Antiseptic Powder it is recommended that a copy of this report be sent to the Commissioner of Patents as a protest against the present law, which authorizes the granting of patents on unproved and improbable medical claims.--(_From The Journal A. M. A., Nov. 14, 1914._) TYREE’S ANTISEPTIC POWDER[E] Report of the Council on Pharmacy and Chemistry with Comments [E] See also Tyree’s Antiseptic Powder, p. 404.
