lines 49 and 50). In one aspect of Example 8, “a roll of film
was passed under the light [an ultraviolet unit using a medium
pressure mercury arc lamp] (reel-to-reel) at a speed of 10
m/minute” (page 11, line 56).
In the examiner’s view (see page 4 in the answer), Speer
responds to all of the limitations in independent claims 26
and 32 except for those relating to the “pulses of UV light”
and the “series of rollers that define a film path.” The
examiner relies on Dunn to overcome these deficiencies.
Dunn discloses methods and apparatuses which utilize
short intensive pulses of incoherent, broad spectrum
(polychromatic) light having a wavelength distribution such
that at least about 70%, and preferably at least about 95%, of
its electromagnetic energy is distributed in a wavelength
range of from 170 nanometers to 2600 nanometers to inactivate
microorganisms and/or enzymes on food products and packages
(see column 4, lines 5 through 58). According to Dunn,
“[a]pplication of pulses of high intensity, incoherent
polychromatic light provides efficient, effective, high
throughput processing and results in many practical and
