    “configuration in which the emitter area and back surface field area are not adjacent to each other, thus eliminating “the necessity of performing an isolation process when the emitter area [] and the back surface field are [] are formed to be adjacent to each other.” Resp. 42 (citing Ex. 1013 ¶ 76). In so doing, Patent Owner side steps Chang’s unambiguous definition that “‘entirely formed’ means that an element such as a layer is formed over an entire surface without an empty area or a non-coverage area, or is formed over an entire area excluding pre-designated or inevitably formed regions such as periphery region, isolation region or the like.” Ex. 1013 ¶¶ 45, 51, 56, 62 (emphasis added). Chang discloses that a first tunneling layer, a first portion of an emitter area, a second tunneling layer, and a back surface field area may each be “formed over an entire area excluding pre-designated or inevitably formed regions such as periphery region, isolation region or the like.” Id. Chang’s definition of “entirely formed” (“excluding pre-designated or inevitably formed regions such as periphery region, isolation region or the like”) implies use of a mask. See Chang ¶ 62; Tr. 15:20–17:11. Dr. Banerjee testifies that the need to electrically isolate the emitter region from the back surface field was well known in the field, and both Chang and Jin teach backside isolation regions. Ex. 1003 ¶¶ 73, 217 (citing Ex. 1023 § 1). Chang also discloses that the emitter area may be formed by thermal diffusion, ion implantation or the like. Ex. 1013 ¶ 98. Petitioner persuasively argues that Chang’s disclosure of thermal diffusion of the emitter layer would result in dopants diffused into not only the top surface of the substrate, but also the exposed lateral surfaces, a problem also noted in Jin. See Pet. 11–12; Reply 6–7; Ex. 1003 ¶ 71; Ex. 1009 ¶¶ 57–58. Jin discloses avoiding shorting of the emitter layer and back surface field layer by edge isolation on the back surface field layer using a mask to create a “gap-T.” Ex. 1009 ¶¶ 57–58, 83. Chang discloses excluding a tunneling layer and a base surface field area from periphery region and isolation region. Ex. 1013 ¶¶ 56, 62. Using a mask, as implied in Chang and explicitly disclosed in Jin, would “pre-designate” and/or “inevitably form” the regions where the tunneling layer and back surface field area are excluded. We credit Dr. Banerjee’s testimony that one of ordinary skill in the art reviewing Chang would therefore understand the importance of implementing the isolation region in Chang’s device, and would therefore be motivated to look to other references, such as Jin (which was assigned to the same original assignee as Chang, LG Electronics, EX1009-Jin, face; EX1013-Chang, face) to understand details regarding Chang’s isolation region.” slip op. at 32

    “On this complete trial record, we agree with Patent Owner. It is improper to base a conclusion of obviousness upon facts gleaned only through hindsight. “The invention must be viewed not after the blueprint has been drawn by the inventor, but as it would have been perceived in the state of the art that existed at the time the invention was made.” Sensonics, Inc. v. Aerosonic Corp., 81 F.3d 1566, 1570 (Fed. Cir. 1996) (citing Interconnect Planning Corp. v. Feil, 774 F.2d 1132, 1138 (Fed. Cir. 1985)). Therefore, “to establish a prima facie case of obviousness based on a combination of elements disclosed in the prior art, the [Petitioner] must articulate the basis on which it concludes that it would have been obvious to make the claimed invention.” Id. Impermissible hindsight is inferred when the specific understanding or principle within the knowledge of one of ordinary skill in the art that would motivate one (with no knowledge of the claimed invention) to make the proposed combination has not been explained.

    “However, Petitioner proposes to remove the tunnel oxide layer from the edge and offers little explanation of why the skilled artisan would apply Jin’s gap- T isolation region to both of Feldmann’s polysilicon and tunnel oxide layers. As noted above, Petitioner states that the skilled artisan would have included Jin’s gap-T isolation region in order to prevent shorting. Pet. 25. Petitioner’s reasoning is questionable—supported only by the conclusory testimony of Dr. Banerjee. Dr. Banerjee’s testimony offers no more evidentiary support than provided in the Petition. Compare Ex. 1003 ¶ 113, with Pet. 25. Petitioner cannot satisfy its burden of proving obviousness by employing “mere conclusory statements.” Magnum Oil, 829 F.3d at 1380. We acknowledge Dr. Banerjee’s testimony that the combination of Jin’s gap-T isolation region would prevent shorting and that extending the tunnel oxide layer the edge “could trap impurities and create negative fixed oxide charges, which could then create a p-type inversion in the n-type base substrate, leading to a leakage path to the p-type emitter on the front of the solar cell” (Ex. 1003 ¶ 113 (emphasis added)) but are not convinced by his equivocal testimony. Notably too, neither Jin nor Feldmann discuss issues relating to trapped impurities and Petitioner, as well as Dr. Banerjee, fail to direct our attention to any record evidence to support their contentions. Rather, we are persuaded by Dr. Peckerar’s testimony that as a general rule in semiconductor process technology, a bare silicon surface should not be left unpassivated after processing. Elemental silicon is highly chemically reactive. As such, the bare surface is a “magnet” for defects and contamination. Leaving the tunnel oxide in place across the entire substrate backside would reduce this problem. Ex. 2001 ¶ 142. Dr. Peckerar further explains that a person of ordinary skill in the art would have known how to avoid shorting and leakage. In particular, he testifies that the manner by which charge is transported through a tunnel oxide can be controlled by adjusting manufacturing parameters such as time, temperature, thickness, and ambient impurities. A POSITA would plainly have adjusted these parameters to ensure that the tunnel oxide operates as intended (i.e., minimizes recombinant losses while transporting charge carriers to the backside of the solar cell) while avoiding undesirable leakage current. Because unwanted leakage charge can be avoided via other means during manufacture, there would have been no reason to reduce the physical extent of the tunnel oxide.” slip op. at 18

    “explained below, we agree with Petitioner that Patent Owner’s additional requirement of evaluating the calibration data to determine the boundaries of the area represented by a grid point should not be included in the construction of either “grid point” or “non-uniform grid point.” Instead, based on the full record, we discern no reason to alter our prior construction of “grid point” as “a point associated with representative calibration data for an area” and maintain that construction for this Final Written Decision. The construction of “grid point” we adopt is supported by the Specification of the ’104 patent. Namely, the ’104 patent discloses that “[i]n general, a non-uniform grid point (NUG) may represent the signal characteristics and/or calibration data over a given region,” and “NUGs represent an area of collected calibration data.”18 Ex. 1001, 3:50–60. The district court identified the second quoted passage, which is identically recited in the ’104 patent (see Ex. 2018, 3:56–60) as “provid[ing] a clear indication of the meaning of ‘grid point.’” Ex. 2012, 19 (emphasis added). We agree with the district court’s analysis. Although the ’104 patent does not explain how a generic “grid point” might differ from the described “nonuniform grid point,” we do not find this distinction pertinent to construing “grid point” in this case because neither party raises this issue. Also, based on the claim wording “non-uniform grid point,” a “non-uniform grid point” is a type of grid point. See Pet. Reply 3 (explaining why that plain meaning supports Petitioner’s proposed construction). Furthermore, the district court construed “grid point” only, not “non-uniform grid point.” Ex. 2012, 18–20.” slip op. at 27

Holdings, summaries, rulings, issues, outcomes, winners and claim constructions shown for a decision were generated by a large language model reading the opinion. They are a guide to the decision, not the decision. Confirm every one against the court's own text before relying on it. Outcomes read from the patent owner’s side. Party names are extracted from the decision and are missing on about 900 short Director denials and scans, which carry the trial number instead.
