Patent Owner further stated that it disagreed with the Examiner’s statement that paragraph 15 of the specification6 defines width in terms of the number of receptacles and that such a definition of width makes no sense in view of other claims where the standard with is defined in terms of a width of front edge of a tray on which the cassettes are secured.

“Owner’s challenge to Petitioner’s Fukui-based grounds is whether, in Fukui, a conversion module (e.g., 20) that is formed by coupling together two unit modules establishes that conversion module as a new structure identifiable as a unitary cassette.11 We discern that Fukui uses the term “conversion module” to refer to component 10, and uses that same term, i.e., “conversion module” to refer to component 20. See, e.g., Ex. 1004, 6:33–35, 7:23–25. The components 10A and 10B that make-up conversion module 20 are characterized as each being a “unit module.” See, e.g., id. at 7:25–27. Thus, once unit modules 10A and10B are coupled together to form the structure that is “conversion module 20,” the current record reasonably suggests that the conversion module 20 is a component analogous to conversion module 10, but with a larger width, i.e., two times the width. Further, Fukui also characterizes unit modules 10A and 10B as being “fixed” to one another via coupling member 21 (see, e.g., id. at 10:11–16) forming “one body” (see, e.g., id. at 8:2–3). Further still, as described and shown in Fukui (e.g., Figure 5), conversion module 20 is structured to operate via a singular multicore optical connector 16 from which optical fibers F1 extend to all of the single-core optical connectors 17 of the conversion module. Id. at 7:52– 11 There is no dispute on this record that the term “module” as used in Fukui is analogous to the term “cassette” as used in the ’423 patent. 8:6.

“Petitioner counterargues that it is not required to show why a person of ordinary skill would have considered every permutation of these references together and that it provided specific reasons for including features of Isaacson into Lisogurski’s device. Pet. Sur-reply 24–25. According to Petitioner, a person of ordinary skill would have had reason to incorporate Isaacson’s sensor (an arrangement of LEDs and detectors) into Lisogurski’s device, which taught that any known sensor layout could be used. Id. (citing Ex.1011, 17:39–45; Ex.1003 ¶¶ 239–240). Petitioner further argues that the ordinarily skilled artisan would have looked to Isaacson because it discloses a known arrangement for that the sensor component of Lisogurski’s device, and because it also taught solutions to potential problems identified in Lisogurski (e.g., with skin pigmentation).

Because Petitioner has not shown that all of the relied-upon portions of Saxonov are prior art to the ’170 patent, we determine that Petitioner has failed to demonstrate a reasonable likelihood that it would prevail in showing the unpatentability of at least one challenged claim of the ’170 patent in any of the remaining grounds.” slip op. at 24

First, we consider whether the same or substantially the same prior art or arguments previously were presented to the Office. Second, if either condition is satisfied, we assess whether the petitioner has demonstrated that the Office erred in a manner material to the patentability of the challenged claims.

“Petitioner contends: A person of ordinary skill in the art (“POSA”) at the time of the alleged invention of the ’223 patent would have had a university degree in chemistry and additional expertise or a second university degree in the field of electrical engineering, particularly optoelectronics, or alternatively a university degree in electrical engineering and additional expertise or a second university degree in the field of chemistry. The person of ordinary skill in the art has spent several years studying the structure and function of organic optoelectronic components, in particular OLEDs, and has detailed knowledge of the chemical structure of light-emitting organic layers and the transport of charge carriers to these layers. In this respect, the person of ordinary skill in the art works at the interface between electrical engineering/physics (charge carrier transport and light emission processes in optoelectronic components) and chemistry, in particular organic chemistry (materials and layer stack combinations suitable).
