An extraordinary collection of patents from Tesla’s most fruitful period, comprising almost half of all the US patents granted to him. The collection includes Tesla’s patent (645,576) for the invention of radio, one of the key technological inventions of the last century – this was disputed by Marconi, but almost half a century later the US Supreme Court ruled that Tesla had priority. Further important patents in the collection include that for the ‘Tesla coil’ (462,418), which was the basis of his method of wireless power transmission; for remote-controlled devices (613,809), which anticipated robotics; and those for his systems of power transmission, AC motors, generators, incandescent arc-lighting, transformers, etc. In 1980, John T. Ratzlaff published Dr. Nikola Tesla. Selected Patent Wrappers from the National Archives. He wrote: “Twenty of the Tesla patent wrappers have been selected for this publication on the basis of importance and current interest.” Of these 20 patents, 16 are in the present collection. Tesla described the principle of radio communication, and gave a demonstration, in a famous lecture at St. Louis in 1893, but due to various personal difficulties he did not file a patent for radio until 1897. “At St. Louis [Tesla] made the first public demonstration ever of radio communication, although Marconi is generally credited with having achieved this feat in 1895” (Cheney, p. 68). “What Tesla described in this lecture should be taken to be the foundation of radio engineering” (Sarkar, p. 271). “He was an inventor, an engineer, a scientist and an oddball. It was Tesla, not Marconi who invented radio … more than any one man, Nikola Tesla is responsible for the twentieth century” (Hunt, introduction to Nikola Tesla: My Inventions and Other Writings (2011)). In his speech presenting Tesla with the Edison medal in 1917, B. A. Behrend, Vice President of the American Institute of Electrical Engineers, stated: “Were we to seize and eliminate from our industrial world the result of Mr. Tesla’s work, the wheels of industry would cease to turn, our electric cars and trains would stop, our towns would be dark and our mills would be idle and dead. His name marks an epoch in the advance of electrical science.” “Patents issued to Nikola Tesla represent the culmination of his creative efforts and, therefore, must be considered as a basic source of information … The contents are of the greatest importance to the understanding of Tesla’s inventions and discoveries, some of which were made nearly a century ahead of their time” (Ratzlaff, pp. vii-viii). These patents are the originals issued by the US Patent and Trademark Office (USPTO). At least two copies of a patent would be sent to the applicant, or more usually their attorneys. According to the archivist at the USPTO, these copies of Tesla’s patents are very probably those sent by the USPTO to his attorneys. Evidence includes the three staples (as on all original copies the Office would send to the Applicant), the annotations on the front of each patent and the lack of any additional printing on the documents. Some of the patents have the name of the printer, the Norris-Peters Company of Washington DC who printed the patents for the USPTO. All of these patents are of extreme rarity. We have been unable to locate any other copies, other than the original ‘Letters patent’ issued by the USPTO and now held at the US National Archives. None are listed on OCLC, and only one Tesla patent (a minor one relating to his system of AC power transmission) has ever appeared at auction.

A list of the patents follows (the first date is when the patent was filed; the second is when it was granted). Those with a * were selected by Ratzlaff for their importance.
