Dating back to 1518 with the invention of the printing press, rabbinic authorities have issued exclusive printing privileges. These privileges typically grant the printer an exclusive right to print the book for a period of ten to twenty years or until the first edition has been sold—a time suitable for the author or heirs to have recovered their investment in preparing the manuscript for publication. In the 19th century, after the introduction of copyright in contemporary secular law, rabbinic authorities argued over the application of copyright in Jewish law. According to Schmelkes' teacher Rabbi Nathanson, a copyright was a property right arising out of the right of ownership. Schmelkes argued that an author’s exclusive right to publish their manuscript derived from the author's copyright in secular law, not from the author's property right in controlling access to the physical manuscript. Rabbi Schmelkes position is held by the majority in contemporary arguments over intellectual property in rabbinic law.^[4]

For appliances that do not produce light on Shabbat, turning on an electric current may violate other prohibitions in rabbinic Jewish law. For example, the Talmud prohibits the creation of a fragrant scent in one's clothing on Shabbat because, according to Rashi "creating anything new" is prohibited under a Rabbinic category called molid. Rabbi Schmelkes suggested applying molid to the generating of electric current.^[5]
