Concerning the proposed combination of Furrer and Alvarez, Mr. Bauer testifies why a person of ordinary skill would combine Furrer and Alvarez, explaining that: a POSITA6 would have turned to the teachings of Alvarez to implement Furrer’s vacuum pump using a conventional pump controller having a portable, battery-powered pump to not only increase portability and to allow the user to move about when using the device but also to provide improved control for the system.

- Claim Construction › Intrinsic evidence (Phillips canons) › Plain and ordinary meaning to a POSITAPlain and ordinary meaningDecided for patent owner
“meaning of “icon” as claimed, including the dependent claims, the specification, the prosecution history, and the extrinsic evidence including expert testimony and dictionary definitions, we determine that the plain meaning of “icon” is readily apparent from the claims themselves. See Phillips, 415 F.3d at 1314 (“In some cases, the ordinary meaning of claim language as understood by a person of ordinary skill in the art may be readily apparent even to lay judges.”). We find that the plain meaning of “icon” as claimed encompasses at least “textual elements” because claim 20 recites “the icons comprise textual elements.” See id. (“Other claims of the patent in question, both asserted and unasserted, can also be valuable sources of enlightenment as to the meaning of a claim term.”). We highlight that the additional intrinsic evidence cited by the parties is consistent with the plain meaning. For example, Figures 1 and 2 of the specification show icons comprising textual elements. As another example, during prosecution of the ’058 patent, the Examiner found that the claimed icons were taught by textual hyperlinks. Ex. 1002, 586, 592. In order to overcome the Examiner’s rejection and obtain an allowance (id. at 641–50), applicant subsequently amended the claims to recite “specifically designed,” thus implicitly conceding to the Examiner’s interpretation of icon as encompassing textual hyperlinks. Id. at 625–640; see PO Resp. 43–44 (citing Ex. 1002, 626–27, 645–46) (acknowledging that the Examiner allowed the claims because applicant amended the claims to recite “specifically designed for containing a set of icons.”).” slip op. at 11
- Claim Construction › Intrinsic evidence (Phillips canons) › Prosecution history disclaimer / disavowalTerm construed petitioner constructionDecided for petitioner
“Requiring an element to be "specifically designed" for another element narrows the claim because it requires more than the first element being merely capable of being used with the second element. The term "configured to" is generally construed narrowly to mean "made to" and "designed to" rather than broadly to require merely "capable of". See In re Giannelli, 739 F. 3d 1375, 1379-80 (Fed. Cir. 2014) (the phrase "configured to" requires more than "mere capability." Rather, that term is synonymous with "made to" and "designed to."). However, rather than use "configured to", in order to avoid any confusion as to the narrower scope of the claims as amended, Applicant herein directly and explicitly requires "designed to." In re Giannelli at 1379-80 (Fed. Cir. 2014) (reversing an obviousness rejection because (1) the claims were properly construed narrowly to mean "designed to" and not broadly to encompass merely "capable of", and (2) the USPTO had not explained the motivation for modifying the prior art to meet the "design to" requirement) See also MPEP 2111.04, citing to In re Giannelli, for the proposition that a claim can be narrowed to require that it be "designed and constructed to be used" in a specific manner (as a rowing machine in the case of In re Giannelli). Logan has not been specifically designed and constructed in the required manner, so it does not cure all deficiencies of the primary reference Iki (which lacks any tree menu structure). Logan describes only "remote web" pages 90, 95 that are merely pages retrieved from Web browsing and stored in a web computer 25. Iki as modified by Logan would result on in a tree menu structure wherein not all levels of the tree included the required selection pages specifically designed for containing the claimed set of icons.

Id. at 23–25 (citing Ex. 1003 ¶¶ 96–100; Ex. 1004, Figs. 4D–F). Petitioner contends that the selection page of Rossmann as modified by the bookmark set of Himmel teaches a first locally stored page specifically designed to include a direct access icon because the selection page is “used to include” a direct access icon, such as on sale today, and that during use, this selection page is programmed to display the set of direct access icons for selection by the user.

Mr. Bauer testifies: The flexible diaphragm [diaphragm 7 in Fang] forms a watertight and airtight seal around its outer edge. In doing so, the diaphragm prevents the passage of milk from reaching the air pump and facilitates generation of negative pressure during operation.

“Here, we disagree with Patent Owner’s argument because it is based on the premise that the second map image is different from the first in a way that is not reflected in the claims. See Section II.C.3 supra. Even if “the claims consistently use the terms ‘first’ and ‘second’ to refer to separate and distinct elements,” A3UM’s first and second map images are separate and distinct elements for at least the reason they are included in separate and distinct views in the interface. See Pet. 63; Reply 5. As discussed in Section II.C.3, the second map image is the map image in the second person view.

RulingsFinal written decision- Skill levelSkill level board ownDecided for patent owner
“On the initial trial record, we agreed with Patent Owner that one of ordinary skill in the art would have had experience with next generation sequencing, but were not persuaded that this would only be possible in the field of molecular biology. Instead, we found that a person of ordinary skill would have had either (1) a Ph.D. in the field of chemistry, molecular biology, or biochemistry or (2) a B.S. or M.S. degree with three to five years of experience working in any of those fields. Inst. Dec. 8. We specifically found that “[t]he person of ordinary skill would have had experience with next generation sequencing methods and a working knowledge of how those methods functioned.” Id. at 8–9. Patent Owner now submits that it does not dispute the definition of a person of ordinary skill in the art as laid out in the Institution Decision. PO Resp. 13. Reviewing the entire trial record, we maintain the same definition of a person of ordinary skill in the art and note that it is consistent with the skill level reflected in the disclosures of the ’357 patent and prior art. We further note that the skill level does not affect our analysis or our final decision.” slip op. at 10

“In the Institution Decision, the Board adopted Petitioner’s construction of the term “adaptor.” Inst. Dec. 9. Patent Owner does not dispute this construction. PO Resp. 13–14. During oral argument, Petitioner argued that claim 1 requires “an adapter to be ligated onto a target DNA, and that adapter needs to have two different sequences of DNA that are used for identification” including a “socalled identifier that's one to eight nucleotides in an indexing site.” Tr. 6:19–7:2. Patent Owner, again, did not dispute this characterization of “adaptor.” See generally Tr. Based on the entirety of the trial record, we continue to apply Petitioner’s construction of the term “adaptor,” although we note that it does not affect our analysis.” slip op. at 12

“Based on the entirety of the trial record, we do not agree with Patent Owner’s reading of either the claims or the prior art because Patent Owner takes too narrow a view of both. First, based on the plain language of Porreca, we find it uses a combination of the sequence reads of the target sequence and differentiator tag sequences to determine whether there is duplication. See Ex. 1006 ¶¶ 139–140, 143, 148, 153. All that the claim requires is that the method identifies sequence reads with identical identifier and target sequences as duplicates. Because claim 1 contains the transition “comprising,” the claim is still satisfied if the category of identified duplicate reads contains identical labels and also contains more. Patent Owner admits that the identifier and target sequence do not have to be used simultaneously. Tr. 46:16–48:4. Instead, Patent Owner challenges whether Porreca uses the required elements in combination as recited in the challenged claims. Based on the record before us, we agree with Petitioner’s position especially in view of the open-ended nature of the claims and Patent Owner’s own admission that there is no temporal requirement for the use of target sequences and differentiator tag sequences. Specifically, we find that Porreca teaches using the combination of the target sequences and the differentiator tag sequence to determine whether particular sequence reads are unique or PCR duplicates. See Ex. 1006 ¶¶ 139–140, 143, 148, 153. The use of both such sequences meet the claim limitations. This finding is consistent with the prosecution history of the ’357 patent and how the applicant and examiner interpreted the claims. See Ex. 1013, 69–70, 78–79. Second, we find the disclosure of Porreca sufficient to demonstrate to an ordinarily skilled artisan that “collapsing” is done by comparing target sequences and differentiator tag sequences. Porreca specifically explains that: after multiple reads have been collected for a given locus, it is possible that due to bias (e.g., caused by PCR amplification steps), a large fraction of the reads are derived from a single originating molecule. This would skew the population of target sequences observed, and would affect the outcome of the genotype call.” slip op. at 30
- Obviousness (§103) › Motivation to combine / reasonable expectation of successMotivation foundReasonable expectation foundDecided for petitioner
“We do not agree with Patent Owner for at least two reasons. First, Patent Owner fails to address the fact that Schmitt cites to McCloskey 2007. We find that the citation of McCloskey 2007 in Schmitt indicates that the ordinarily skilled artisan would have considered the teachings of McCloskey to be highly relevant to the teachings of Schmitt and would have considered them to be both useful in the field of sequencing. See Ex. 1005 ¶ 6. Second, Patent Owner fails to explain or even identify the purported structural differences between Schmitt and McCloskey that would prevent the teachings of McCloskey from being relevant to Schmitt. In addition, we credit the testimony of Dr. Metzker that one of ordinary skill in the art would have understood the benefits of adding a barcode to target sequences and would have looked to McCloskey and the batch-stamps it teaches because both Schmitt and McCloskey are in the same field and address the same problems. See Ex. 1003 ¶¶ 110, 114. Accordingly, we find that Petitioner has demonstrated by a preponderance of the evidence that a person of ordinary skill in the art at the critical time would have had sufficient reason to combine the teachings of Schmitt and McCloskey to arrive at challenged claim 1.” slip op. at 48

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. Ex. 2001 ¶ 152 (referring to Ex. 2001 ¶¶ 149–151). Moreover, Dr. Peckerar testifies that “Dr. Banerjee also appears to be arguing that incorporation of impurities into the oxide will produce a MOSFET-like structure, with the contaminated oxide acting as a MOS gate leading to enhanced leakage,” but, for that to occur, “the source and drain areas would need to be of the same type.” Ex. 2001 ¶ 159. Here however, “the tunnel oxide layer is located between an n-type polysilicon layer and p-type frontside emitter layer” so “[n]o MOSFET-like structure can form because the source and drain are of different types.” Ex. 2001 ¶ 159.

“Patent Owner focuses on Chang’s description in paragraph 76 of a single 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
