Patent

Since the perfection of the early form of talking pictures (sound-on-record), many companies have been experimenting with the photography of sound on the film itself. A new sound-on-film process worked out by Inventor Theodore Nakken, president of Nakken Corp., discards the use of a slit device for limiting the area of photographic sound on a film. Claiming sole rights to this method, and also to the sound-on-film device which employs the slit (Fox Movietone, Metro-Goldwyn-Mayer, RKO, Paramount), Nakken Corp. has requested an adjudication of patents from the U. S. Patent Office. Last week Warner Brothers--following their policy of pioneering with picture patents--bought 50% of Nakken Corp. stock thus acquiring the use, free from royalty, of all Nakken Patents. If the courts grant Nakken Corp. its patent claims, all other companies using sound-on-film will have to pay royalties for their talking pictures to Nakken and the Warners.
