Tesla's Wireless Patents - Comments on Tower Sale and Patents

To the Editor of The World:

As bearing intimately on the report in your issue of even date that my tower is to be sold for $199.81 on Dec. 9, which, to use Mark Twain's phrase, is "greatly exaggerated," your readers might be interested to know that, among others, the following patents, on wireless transmission, transformation and utilization of energy have been granted, to me in the United States: Nos. 568,176, 568,178, 568,179, 568,180, 577,670, 645,576, 649,621, 685,955, 685,954, 723,188, 725,605, 787,412.

These documents, most carefully drawn with the assistance of some of the ablest attorneys, set forth clearly my fundamental discoveries on which this novel art is based, and give faithful description of my processes, apparatus and experiments. thus enabling experts not only to flash wireless telegraphic and telephonic massages to any distance, but also to transmit power in unlimited amounts and with the highest economy.

Copies of these specifications can be readily obtained by addressing a courteous request to the Honorable Commissioner of the Patent Office, Washington, D. C. inclosing $1.20 postage stamps.
