John Lapp comments on Boch patent infringement case

GLAZE FILLED INSULATORS.—Mr. J. S. Sapp [sic] Lapp, of the firm of Fred M. Locke, Victor, N. Y., favors us with the following: "My attention has been called to an article in your issue of Dec. 29, 1900, entitled, 'Glaze Filled Porcelain Insulators.' In view of the fact that some of your subscribers who are not familiar with the status of the case therein mentioned may be misled thereby, I beg leave to call attention to the fact that the decision cited in no way affects the insulators made by us. The patent mentioned as granted to Boch being a process patent, only relating to one method of glazing insulators made entirely of porcelain. The litigation in no way affected the Locke patent of Dec. 15, 1896, covering high voltage insulators claim three of which reads as follows: 'An insulator comprising two members respectively composed of insulating materials having different degrees of puncturability and having various degrees of surface resistance connected together and adapted to be supported substantially as shown and described as a means for insulating currents of very high voltage.'"
