“STANDARD A party requesting rehearing bears the burden of showing that a decision should be modified. 37 C.F.R. § 42.71(d). The party must identify all matters it believes the Board misapprehended or overlooked, and the place where each matter was addressed previously in a motion, an opposition, or a reply. Id. When rehearing a decision, we review the decision for an abuse of discretion. See generally 37 C.F.R. § 42.71 (b)–(d).

“Patent Owner fails to cite any authority to support its argument that we should, in effect, disregard Mr. Klass’ testimony as to the level of ordinary skill in the art because he is not a person of ordinary skill in what Patent Owner contends is the relevant field. See PO Resp.; PO Sur-Reply. Patent Owner’s counsel similarly was unable to identify any such authority at the hearing. Tr. 42:9–15. Further, Mr. Klass’ testimony was not that he is not a person of ordinary skill in the art, but rather that his opinions set forth in his earlier declaration would not be different under the level of ordinary skill as defined by Mr. May. Ex. 1028 ¶¶ 4–5. On this record, we find Mr. Klass’ testimony well-supported as it pertains to relevant issues and see no reason to summarily disregard it. See Exs. 1002, 1028. Complete overlap between a witness’ technical qualifications in the field of the invention is not necessary for the witness’ testimony to be admissible. See SEB S.A. v. Montgomery Ward & Co., Inc., 594 F.3d 1360, 1372–73 (Fed. Cir. 2010); see also Patent Trial and Appeal Board Consolidated Trial Practice Guide November 2019 (“CTPG”)5 at 34 (“There is . . . no requirement of a perfect match between the expert’s experience and the relevant field.”). Nor must they themselves be a person of ordinary skill in the art, but only that they are “qualified in the pertinent art.” CTPG at 34 (citing Sundance, Inc. v. DelMonte Fabricating Ltd., 550 F.3d 1356, 136364 (Fed. Cir. 2008)). Mr. Klass’ education includes a minor in Pulp & Paper Technology (Ex. 1006) and his lengthy experience in the pulp and paper industry includes work—as a process engineer—involving splicing and corrugators (Ex. 1002 ¶ 8). Mr. Klass has the “knowledge, skill, experience, training, [and] education” of a “specialized” nature that is likely to “assist the trier of fact to understand the evidence.” Fed. R. Evid. 702.

“On this record, we determine that a person of ordinary skill in the relevant art would have included those with a bachelor’s degree in mechanical or paper engineering with at least a year’s experience relating to producing cushioning materials, dunnage pads, and other protective packaging. As admitted by Patent Owner, production of such materials using kraft paper stock was known. PO Resp. 14. As to the use of double-sided adhesive, we do not agree with Patent Owner that it was unknown to the person of ordinary skill in the art because using double-sided tape to join rolls of sheet stock was known in the wider field of paper processing and we find that field reasonably includes producing paper cushioning products, and that such related knowledge reasonably would also have been within the knowledge of a skilled artisan in the “cushioning conversion machine” field as the same or similar paper cushioning products are produced. Moreover, regardless of whether double-sided tape was used in what Patent Owner contends is the “cushioning conversion machine” field, Mr. May’s testimony is limited to it not being used in that field, not that double-sided tape itself was not known to one of ordinary skill in the art in the field. Ex. 2001 ¶¶ 53–57. It reasonably follows that a person having knowledge of double-sided tape would also have knowledge of joining together sheets of paper or other stock using double-sided tape. Further, to the extent that Patent Owner and Mr. May rely on “cushioning conversion machines” differing from paper processing machines that produce paper cushioning products, on this record, there is insufficient evidence of a meaningful difference in their complexity, size, or operation. For example, Patent Owner relies heavily on the paper processing machines including machinery to allow splicing on the fly, but the prior art also teaches that non-continuous roll-to-roll splicing can be used. See Ex. 1010, 1:13–16 (disclosing that a splicing tape system “is applicable both to systems in which the splice is made on the fly and to systems in which the splice is made while the running web is stationary”); Ex.1017, 1:15–19 (disclosing that “[t]he splicing operation can be performed in a static or a dynamic mode.”). As to size, similarly, Patent Owner relies on the machinery for paper making or producing corrugated cardboard being larger than “cushioning conversion machines,” but there is no clear distinction between the two as to size, as discussed below. Also, there is no evidence that paper processing machines forming paper cushioning products from paper itself do not do so in the same general manner as the ’096 patent. Accordingly, finding no meaningful distinction to “cushioning conversion machines,” we discern no meaningful difference in the knowledge of the skilled artisan as it relates to the challenged claims. Moreover, to the extent that there would be a narrower “cushioning conversion machine” field that did not include the use of double-sided tape, as Patent Owner contends, there would be no difference in the outcome of this case. As to obviousness, the scope of analogous prior art is not limited to the field of inventor’s endeavor, but also includes references that are “still reasonably pertinent to the particular problem with which the inventor is involved.” See In re Bigio, 381 F.3d 1320, 1325 (Fed. Cir. 2004). As discussed below, we find Kirkpatrick reasonably pertinent to the particular problem with which the inventor is involved.” slip op. at 12

“On this record, we determine that the preamble’s recitation of “sheet stock material for use in a cushioning conversion machine” is a statement of intended use and does not constitute a limitation. In doing so, we must construe the meaning of the term “cushioning conversion machine.” In construing “cushioning conversion machine,” we note there is no guidance elsewhere in the remaining claim language as to its meaning, including in other claims, and so turn to the specification of the ’096 patent. See Phillips, 415 F.3d at 1312–13, 1315. The ’096 patent states that “[c]ushioning conversion machines convert [paper] sheet stock material . . . into a cushioning dunnage product.” Ex. 1001, 1:23–25 (Background). The ’096 patent also identifies its “invention [as] relat[ing] to machines for converting sheet stock material into a dunnage product.” Id. at 1:15–16 (Field of the Invention). Figures 1 and 2 are identified as top plan and side elevational views of a cushioning conversion machine. Id. at 3:57–63. The ’096 patent discloses that the “operation of the [cushioning] conversion machine 10 may be controlled by a controller, also in a well-known manner” (emphasis added). Id. at 6:42–44. The ’096 patent provides no disclosure as to the size of the cushioning conversion machine or the sheet stock material that it converts into cushioning dunnage product. See Ex. 1001.” slip op. at 20
- Claim Construction › Intrinsic evidence (Phillips canons) › Plain and ordinary meaning to a POSITATerm construed board ownDecided for petitioner
“On this record, Mr. May’s testimony of what “cushioning conversion machine” means in the field of paper dunnage machines fails to bear the weight required to limit the term as Patent Owner proposes. The ’096 patent identifies “cushioning conversion machines” to be machines that “convert sheet stock material . . . into a cushioning dunnage product.” Ex. 1001, 1:23–25 (Background). This is in effect the plain and ordinary meaning of the words themselves identifying a machine that converts feedstock into cushioning. Further, we find it consistent with the ’096 patent as a whole. Mr. May’s contrary testimony, as discussed above, lacks sufficient evidentiary basis to support Patent Owner’s contended construction over the plain and ordinary meaning. In effect, the basis for Mr. May’s testimony is limited to a showing that the meaning of the term encompasses a machine such as shown in the ’096 patent’s Figure 1 and 2. Mr. May’s testimony as to the PadPak machine being a “popular cushioning conversion machine[]” only goes to establishing that “cushioning conversion machine” encompasses similar machines, not that the term would be understood to be limited to the PadPak machine. Ex. 2001 ¶¶ 65–66. As to “cushioning conversion machines” being stop/start machines, the ’096 patent’s states that “the conversion machine 10 may be controlled by a controller” (emphasis 7 Elsewhere Patent Owner cites a number of its patents for using the term “cushioning conversion machine,” but this only supports that Patent Owner uses the term. See PO Resp. 27. added), not that it must be. Ex. 1001, 6:42–43. As to size, as discussed above, the ’096 patent provides no limitation as to the size of the apparatus or the sheet stock material. Petitioner highlights that another of Patent Owner’s patents, U.S. Patent No. 6,200,251 B1 (Ex. 1026, “the ’251 patent”), discloses “that in a ‘preferred cushioning conversion machine, the stock supply assembly is adapted to supply stock material which is between 25 to 35 inches wide’” (emphasis added). Pet. Reply 14 (citing Ex. 1026, 2:56–59). Petitioner also highlights that the ’251 patent was filed before the ’096 patent’s priority date and names the ’096 patent’s inventor among its inventors. Id.; compare Ex. 1026, codes (22), (75), with Ex. 1001, codes (22), (75). Such disclosure of a preferred embodiment in this circumstance is reasonable evidence that a skilled artisan would understand that a “cushioning conversion machine” included those “adapted to supply stock material . . . between 25 and 35 inches wide,” but not that such machines were limited to using such widths. The relevance of this is that the sheet stock material used is not manifestly distinct from the sheet stock material used for corrugators, ranging from 35 to 110 inches in width, where Patent Owner contends corrugators are distinct from “cushioning conversion machines.” See Ex. 2003, 95:22–96:6 (Mr. Klass testifying that the “width of commercial corrugators could be anywhere from 35 to 110 inches.”); PO Resp. 33–34 (relying on Mr. Klass’ testimony). Similarly, there is no persuasive evidence of a clear distinction in weight. Patent Owner and Mr. May rely on Mr. Klass’ testimony as to the weight of paper rolls for corrugators, focusing solely on testimony as to the weight of large rolls and ignoring that the testimony also set forth that “[s]ome corrugators use smaller rolls.” PO Resp. 34; Ex. 2001 ¶¶ 77–79; Pet. Reply 14–15; see also Ex. 1028 ¶¶ 21–22 (Mr. Klass’ testimony that “web feed rolls at the lower end of that range would be especially well suited for use in a cushioning conversion machine, even under [Patent Owner’s] narrow definition of such a machine” and that “my testimony certainly was not that Kirkpatrick’s web feed rolls would weigh tons.”).

“On this issue, we agree with Petitioner. Mr. Gardner explains that the skilled artisan “would further recognize that the output conductor can be comprised of various materials . . . . which could be metal or various materials . . . . [and] the shape of the output conductor is not particularly limited.” Ex. 1003 ¶ 322. Mr. Gardner further testifies that a person of ordinary skill in the art “would recognize, not only that metal foil conductors could be inserted into these grooves without difficulty, but also that the depth of the grooves can be altered in order to better accommodate metal foil output conductors.” Ex. 1041 ¶¶ 53, 70. We recognize Patent Owner’s argument that numerous factors must be considered and that conventional battery design does not necessarily translate to button cell designs (PO Resp 25–26), but as Mr. Gardner testifies, “this may be true in some cases, [but] the lessons and advantages of using techniques from conventional battery design and applying it to button cell would be obvious to a [person of ordinary skill in the art].” Ex. 1041 ¶ 103. He continues to explain that “[n]aturally, such transposition of techniques would require some modification and adjustments. . . . [and that] each of these adjustments, . . . would be well within the skill of a [person of ordinary skill in the art].” Id. ¶ 104 (describing, for example, “reducing the thickness of the conductor plates of Kobayashi”). We credit Mr. Gardner’s testimony. Moreover, Patent Owner does not allege that any proposed modification would be beyond the skill of a person of ordinary skill in the art or explain how any of the “constraints unique to . . . button cell design” (PO Resp. 25) are relevant to the proposed substitution of a metal foil for a metal terminal electrode plate. See generally id.; Sur-reply. Finally, Patent Owner argues that “[r]eliance upon the general knowledge of a [person of ordinary skill in the art] to provide a missing element in a combination of references is an exception rather than the rule” and “is particularly true where the proposed modification goes to the essence of the claims.” PO Resp. 26. Patent Owner states that “Petitioners have provided no more than ‘conclusory statements and unspecified expert testimony’ to supply a metal foil that is admittedly missing from Kobayashi, and is not shown in any other button cell art.” Id. at 27. We disagree. As the Federal Circuit has explained ‘common sense and common knowledge have their proper place in the obviousness inquiry,’ (a) invoking ‘common sense . . . to supply a limitation that was admittedly missing from the prior art’ should generally only be done when the [missing] limitation in question [is] unusually simple and the technology particularly straightforward;’ and (b) references to common sense ‘cannot be used as a wholesale substitute for reasoned analysis and evidentiary support’ Koninklijke Philips N.V. v.

Here, Petitioner proposes to substitute a metal foil for a metal terminal electrode plate to provide contact with the inner surface of the button cell housing. Ex. 1006 ¶ 34. As detailed above, Petitioner and Mr. Gardner direct our attention to the prior art of record which suggests use of foil within small battery cells to provide electrical contact was well-known and explains why the skilled artisan would have reduced the thickness of the terminal electrode plate to maximize the available space for active electrode components.

“that “Kaun discloses that the cell is sealed ‘by a ‘U’ shaped insulator/gasket 32 . . . to seal the cell without pressure-loading,’” and therefore, venting via a pressure release seal is not required. Pet. 64 (citing Ex. 1005 ¶ 120). In an alternate embodiment, Kaun provides a means to relieve gas pressure “via the peripheral gasket which can reseal after an event.” Ex. 1005 ¶ 91. As Petitioner explains, “Kaun discloses that it is sealed, but upon the application of certain conditions, the internal pressure of gases within the cell can cause gases to vent.

Furthermore, Mr. Gardner testifies that “[i]f a battery which, upon application of significant internal pressure, would be considered not ‘closed’ at other times, th[e]n almost no battery could be considered closed. [Because] [a]ny battery, when subjected to certain pressures, would leak or burst.” Ex. 1041 ¶ 39. We credit Mr. Gardner’s undisputed testimony in this regard.

“Thus, Patent Owner identifies three claimed features—i.e., the jelly- roll configuration, the insulating layer, and a housing closed without being beaded over—as responsible for the improved performance of the VARTA CoinPower® button cell batteries. Id. However, Patent Owner’s declarants testify further and explain that it is the combination of the three identified features, in addition to a flat foil conductor resting flat between the electrode top and housing and welding the foil conductor from outside the housing, that are responsible for improved performance. In particular, Mr. Miehlich, employed in VARTA’s marketing and sales department, testifies that the new cell design, which “provided unprecedented increases in performance, including in energy density, charge capacity, and cycling stability,” consisted of a “jelly roll electrode coil packed tightly into an uncrimped, button-like housing. The electrode coil was protected against short-circuiting by [an] insulating means, and was connected to the cell terminals by a flexible flat foil conductors resting flat between the electrode top and housing, and welded to the housing components from the outside. These features are all found in the claims of the VARTA patents here under review. Ex. 2045 ¶¶ 15–16. And, Dr. Lindner, one of the named inventors of the ’835 patent, testifies that the complex issues we faced were how to safely pack the required amount of electrode material into the very small “button”-sized housing and protect it against short circuits; how to connect the “jelly roll” electrode to the terminals in such a confined space without itself consuming much volume, and how to seal the top and bottom of the cell housing, all while accommodating the expansion and contraction of the electrode winding and the resulting mechanical forces. Ex. 2046 ¶ 33. According to Dr. Linder, the jelly-roll configuration with an insulator, flexible foil output conductors, sealing the cell without crimping, and welding the foil conductors from outside the housing each contributed to the improved battery performance. Id. ¶¶ 34–43. Thus, it is the combination of five elements—not the three claimed in the ’835 patent—that are purportedly responsible for the “vastly increased performance characteristics” of the CoinPower® products. Id. ¶ 43; see also id. ¶ 45 (noting that “various aspects of our invention are covered by 10 issued patents, including the four United States patents here under review” (emphasis added)); Tr. 84:24–85:10 (explaining that welding, for example, is “also part of the success”).

Thus, based on the evidence and argument of record, we determine that the combination of Kobayashi and Kwon, and the general knowledge of those skilled in the art, would suggest the use of foil in place of Kobayashi’s terminal electrode plates, and that the foil would bear flat on one of the lateral ends of the electrode separator assembly.” slip op. at 24

Petitioner explains that one of ordinary skill in the art would have known that metal foil may be used in batteries because the use of metal foil as a conductor is common in the art.

Petitioner asserts that, although dependent claim 12 is indefinite, its language, “to determine one or more axial locations of the anterior capsule of the lens; and or more anterior capsule axial locations,” should be construed to mean “to determine one or more axial locations of the anterior capsule of the lens (i.e., one or more anterior capsule axial locations).” Pet. 7–8; see also Ex. 1030, 18:46–50 (claim 12). Petitioner’s position is that, as it reads in the ’648 patent, claim 12’s language is “a nonsense phrase,” rendering it indefinite, but that for the purposes of this proceeding it may be understood by the definition set forth above. Pet. 7–8. Patent Owner does not ask that any claim language be expressly construed. See generally Prelim. Resp. Claim 12 depends from independent claim 1 and is but one of fifteen challenged claims. Ex. 1030, 17:30–18:61. It is not necessary for us to consider the Petition’s specific challenges to claim 12 to render our decision” slip op. at 25
- Obviousness (§103) › Motivation to combine / reasonable expectation of successMotivation foundReasonable expectation foundDecided for petitioner
“At this stage of the proceeding, we find Petitioner has sufficiently explained how and why the cited prior art would have been combined, why the ordinarily skilled artisan would have had a reasonable expectation of success in doing so, and that such a combination teaches or suggests the limitations or steps of claims 1–5 and 12–15. We address Patent Owner’s preliminary arguments below. Patent Owner addresses Petitioner’s Grounds 1–3 together; each is based on a combination of Swinger, Baikoff, and Li. Prelim. Resp. 10–31 (citing, inter alia, Ex. 1001 (Izatt) ¶¶ 46–49, 143, 149, 159; Ex. 1030, 2:5– 13, 11:19–26, 17:38–45; Ex. 1039 (Swinger), 17:50–54, 19:23–28, 23:28– 31, 34:30–35:3, 35:18–36:17; Ex. 1041 (Baikoff), 1843–45, 1847, 1849, Fig. 10; Ex. 1043 (Hoppeler); Ex. 1044 (Li); Ex. 1046 (L’Esperance); Ex. 2002 (Kang) ¶¶ 32–39, 46–52, 55–57, 60; Ex. 2004 (Walter) ¶¶ 16–17; Ex. 2006, 286, 296–98).15 Patent Owner addresses the claims in this way as a set, presenting the same arguments for all claims, and addresses the dependent claims as not unpatentable because the additionally cited prior art (Hoppeler and L’Esperance) do not remedy the argued shortcomings regarding Swinger, Baikoff, and Li. Id. Patent Owner argues that the ordinarily skilled artisan would not have combined these references because Swinger requires a surgeon’s direct visualization for cataract surgery, foreclosing using OCT, and because Baikoff and Li teach that OCT is limited to the eye’s anterior chamber, which makes it impossible to obtain satisfactory imaging (e.g., of lens portions behind the iris’s shadow). Id. at 15–18. Patent Owner argues that Swinger’s use of direct visualization and Baikoff’s acknowledgement of an inability to OCT-image the lens where shadowed by the iris teaches away from using OCT in cataract surgery and the combination of the references. Id. at 15–19. Patent Owner argues that the prior art combination does not disclose a device that “generate[s] image data for the patient’s crystalline lens,” or “process[ing] the image data to determine an anterior capsule incision scanning pattern for scanning a focal zone of the laser beam for performing an anterior capsule incision,” as recited by claim 1. Id. at 21–30. Patent Owner also argues that Petitioner took positions before the Office contrary to those it now asserts, specifically that in 2010 OCT imaging could 15 Patent Owner cites this evidence by shorthand names, e.g., “Swinger” and “Kang.” Although Patent Owner is free to cite evidence by any manner it desires, it is more useful to the Board if citations reference exhibit numbers, which facilitates review of the record.” slip op. at 29
