Color Photography Patents

DURING a luncheon at which several members of our Society were present, reference was made to a patent, that had recently been issued to me, and one of the party remarked that he was unable to understand the reason for the broad claims that had been allowed. In view of the great number of patents that have issued in this branch of photography, he is interested in knowning what lines of development are still open for improvements by inventors. I am also requested to enlighten the members as to the reason for the apparent similarity in many patients that have issued and if differences exist to point them out where possible.
