The Board instituted PGR on claims 1–24 and all petition grounds, finding it more likely than not that claims 1–3, 5–6, 8–11, 13–17, and 20–24 are obvious over Emma, Butt, and Smith.

“level of smoke” Neither Patent Owner nor Petitioner expressly indicate that any claim terms require express construction. See Petition 13–14; Prelim. Resp 5. However, Petitioner contends that for the phrase “level of smoke,” recited in claims 1, 15, and 22, “Patent Owner interprets ‘level of smoke’ as merely detecting smoke.” Pet. 14 (citing Ex. 1009, 6). Patent Owner argues that it “does not offer a special definition” and “asked the [district] court to give these terms their plain and ordinary meaning.” Prelim. Resp. 5, n 2. Patent Owner explains that a person of ordinary skill in the art “would similarly understand ‘level of smoke’ when read in the full context of the intrinsic record.” Id. in light of the specification, we understand “level of smoke” as a predetermined level of smoke “indicative of a dangerous condition” as the specification of the ’746 patent explains. Ex. 1001, 15:43–44, see also id. at 15:63–65 (The ’746 patent describing “[t]he determination of a level of smoke corresponding to a dangerous condition.”).

“POSITA to reasonably combine Emma with a smoke sensor reference.” Prelim. Resp. 44. We agree that Emma does not disclose a smoke sensor, but Petitioner has provided other prior art references, namely Butt and Smith, and presented several reasons, namely safety reasons, that a person of ordinary skill in the art would consider adding a smoke detector from Butt and Smith to Emma’s microwave oven. Pet. 24, 74–75. Obviousness is not determined from the perspective of the inventors or authors of a single prior art reference. Rather, obviousness is determined from the perspective of a hypothetical person having ordinary skill in the art. It is only that hypothetical person who is presumed to be aware of all pertinent prior art. Standard Oil Co. v. American Cyanamid Co., 774 F.2d 448, 454 (Fed. Cir. 1985). Petitioner argues, for instance, that Butt teaches the fire safety aspects of “a controller for interrupting a supply of electricity to an appliance upon detection of a trigger, such as [s]moke.” Pet. 24 (quoting Ex. 1015, 1:16– 18). Dr. Horenstein testifies that from a safety perspective, a person of ordinary skill in the art would have “combine[d] the additional kitchen-safety appliance features of Butt with the Emma microwave/refrigerator so as to enable the Emma microwave to shut down upon the detection of smoke, and to reenable the Emma microwave for a further cooking session when the smoke had cleared.” Ex. 1023 ¶ 124. Where Butt arguably discloses a smoke detector external to an appliance, Dr. Horenstein testifies that a person of ordinary skill in the art would have looked to “Smith to include the smoke sensor in operative connection with the microwave oven with the reset functionality disclosed by Butt for the added benefit of reusing the microwave oven.” Id. ¶ 127 (emphasis added). each directed towards shutting down a component of the device in response to a sensor output indicative of an unwanted condition.” Id. ¶ 127. Dr. Horenstein testifies further that a person of ordinary skill in the art “would have combined the elements as disclosed by known methods for the purposes of modifying Emma’s microwave / refrigerator combination to include Smith’s smoke sensor to be operatively connected with its cooking area and to include Butt’s smoke sensor and reset functionality.” Id. ¶ 126. Dr. Horenstein explains that inclusion of Butt’s reset functionality with Smith’s smoke sensor operatively connected with the cooking area into Emma would result in such elements merely performing the same function as they do separately, i.e., sensing smoke to withdraw electrical power from an electrical cooking appliance and then re-enabling the electrical cooking appliance. Id. Moreover, Dr. Horenstein testifies that the prior art, for example, Butt, specifically recognized the need to solve the problem of fires in the home started by cooking appliances. Id. ¶ 128 (citing Ex. 1015, 1:22–44). Butt explains, that “[h]ome fires are a serious problem in the United States. The National Fire Protection Association reports that between the years 1999- 2002, for example, there were 114,000 reported home fires associated with cooking alone.” Ex. 1015, 122–25. Similarly, Smith expressly teaches “[a] method and apparatus for anticipating the occurrence of a fire in the cooking cavity of a microwave oven.” Ex. 1014, Abstract.” slip op. at 36
