On October 25, 2016 , the USPTO issued U.S. Patent Number 9,474,440 to EndoChoice, Inc., which was successfully prosecuted by Novel IP.

The '440 patent  is directed towards  an endoscope having a tip section equipped with multiple viewing elements. Each of the viewing elements' field of view is illuminated by a discrete illuminator, such as a LED, being operated in a flash mode. The flash mode of operation of the LEDs enable doctors to obtain a position of the endoscope tip within a patient's body from outside by viewing the light emitted by the LEDs. Since the light is emitted for short pre-defined periods of time, the heat generated by the LEDs during their periods of operation is within a safe threshold value, and does not cause any burn injury inside the patient's body.

Independent Claim 1 describes " A system for managing heat generated in a tip of an endo scope, comprising: a controller external to the endoscope, wherein said controller comprises a memory for storing programmatic functions and a processor for executing said programmatic functions; an input device in data communication with said controller, wherein said input device is adapted to receive data indicative of a programmatic function and wherein said input device is configured to communicate said data indicative of a programmatic function to the controller; and a plurality of discrete illuminators positioned within said tip and in electrical communication with said controller, wherein each of said plurality of discrete illuminators emits an amount of visible light and wherein said controller executes a programmatic function based upon said data indicative of a programmatic function that causes at least one of said plurality of discrete illuminators to operate in a first mode and a second mode, wherein, in said first mode, the at least one of said plurality of discrete illuminators emits said visible light at a baseline illumination level that is greater than zero and wherein, in said second mode, the at least one of said plurality of discrete illuminators emits said visible light at a first illumination level that is greater than the baseline illumination level for a first period of time and at a second illumination level that is greater than zero but less than the baseline illumination level for a second period of time.
