` My opinions on how the disputed terms/phrases identified in paragraph above would
`
`have been interpreted by a person of ordinary skill in the art at the time of invention.
`
`14. In my opinion, a person of ordinary skill in the art on the earliest priority date (i.e.,
`
`December 14, 2012) for claims in the ‘457 Patent and '446 Patent would have no trouble to
`
`ascertaining the meaning of these two terms/phrases. In particular, such a person of ordinary skill
`
`in the art would have interpreted the terms as set forth below:
`
`
`1.
`
`2.
`
`Claim Term
`“a weir … having an overflow lip adapted to
`facilitate substantially uniform recovery”
`
`“a weir … adapted to facilitate substantially
`uniform recovery”
`
`Proper Interpretation
` “a weir … having an overflow edge or boundary
`capable of easing or helping substantially uniform
`recovery”
` “weir … capable of easing or helping substantially
`uniform recovery”

`
`“The module of claim 6 wherein the control facility further comprises a communication facility
`
`adapted to facilitate monitoring and control of the control facility from a remote location.”
`
`
`
`VII. Claim Construction Principles
`19. I understand that claim construction is the process by which a court determines, as a matter
`
`of law, the scope and meaning of terms used in the claims of a patent. I further understand that the
`
`goal of this process is to give claim terms the meaning they would have had to a person of ordinary
`
`skill in the art (“POSA”) at the time of the invention, after reading the entire patent and prosecution
`
`history.
`
`20. I further understand that it is possible that the patent specification and/or file prosecution
`
`history may reveal a special definition given to a claim term by the patentee that differs from the
`
`
`
`- 10 -
`
`Immersion Systems LLC – Ex. 1022
`PGR 2021-00104 (U.S. 10,820,446 B2)
`10 of 135
`
`

`

`meaning it would otherwise have to a POSA. In such cases, I understand that the patentee's
`
`definition usually controls.
`
`21. I understand that the prosecution history of a patent can inform the meaning of some claim
`
`language and must be taken into account in construing the claims.
`
`22. I understand that, in some cases, the court may consider extrinsic evidence, such as
`
`technical dictionaries, treatises, and expert opinions, to understand the underlying technology and
`
`the way in which claim terms would be understood by a POSA at the relevant time. However, I
`
`also understand that such extrinsic evidence should not be used to vary, contradict, expand, or limit
`
`the claim language from how it is defined in the specification or prosecution history.
`
`23. I understand that a patent can be held invalid for indefiniteness if its claims, viewed in light
`
`of the specification and prosecution history, fail to inform with reasonable certainty those skilled
`
`in the art about the scope of the invention. I further understand that definiteness is to be evaluated
`
`from the perspective of someone with skill in the relevant art at the time that the patent was filed.
`
`VIII. Level of Skill in the Art
`24. Having reviewed the ‘457 and ‘446 Patents and their prosecution history, in my opinion, a
`
`person of ordinary skill in the art would have had at least a B.S. degree in the field of mechanical
`
`engineering, or a similar science or engineering degree, and 5-10 years of experience with thermal
`
`systems and thermal management of electronics. For the purpose of this declaration, I understand
`
`the time of invention to be late in the year 2012.
`
`IX. Background Information
`25. A background of the words “weir” and “plenum” is appropriate when considering the
`
`contested terms as summarized in Section V.
`
`a) “weir”
`
`
`
`- 11 -
`
`Immersion Systems LLC – Ex. 1022
`PGR 2021-00104 (U.S. 10,820,446 B2)
`11 of 135
`
`

`

`26. The term “weir” appears in claims 1, 5, 6, 10, 11, 14 of the ‘457 Patent and also appears in
`
`claims 1, 5, 6, 10 of the ‘446 Patent. The term “weir,” means “an overflow structure or barrier that
`
`determines the level of liquid.”
`
`27. The term “weir” appears in the ‘457 Patent specification and drawings at: Abstract, FIGS.
`
`5, 6, 11, 12, 13; Column/line – 3:1-6, 3:16-19, 3:23-25, 3:39-63, 4:30-34, 4:57-58, 8:22, 9:7-24,
`
`9:37-46, 10:20-29, and 10:65-11:3. The term appears in the ‘446 Patent specification and drawings
`
`at: Abstract; FIGS. 5, 6, 11, 12, 13; Column/line – 3:3-8, 3:18-21, 3:25-27, 3:38-58, 4:29-34, 4:57-
`
`60, 8:25, 9:10-27, 9:42-45, and 10:26-29.
`
`28. A weir, generally, can be (and was at the time the ’457 patent was filed) a structure used
`
`in open channels that carry liquids, to control flow and determine the level of the liquid, such as
`
`water. Holding ponds and industrial tanks for handling liquids may include a weir. As one
`
`exemplary reference (hereafter, the “CTG Website”) teaches “in industrial cleaning systems, weirs
`
`perform two basic functions. The first is to establish and control liquid level in a tank or other
`
`vessel. The other is to selectively remove floating contaminants from the surface of a liquid.”
`
`29. A basic weir as used in industrial cleaning applications as taught by the CTG Website.
`
`When the liquid level in the tank exceeds that of the weir, liquid overflows the weir. Figure 1
`
`(below) illustrates two arrangements of industrial tanks for handling liquids, where each liquid
`
`tank includes a weir. As shown in Figure 2 from the CTG Website , weirs may be used to
`
`determine the liquid level in a tank and regulate the flow or discharge of liquid from the tank to
`
`another location.

`
`
`
`30. Weirs generally are structures that have horizontal, vertical and thickness components or
`
`dimensions. The horizontal and vertical components are perpendicular to the channel flow or tank.
`
`Furthermore, weirs have a vertical component from the bottom of the upstream liquid body to the
`
`overflow height. These points are illustrated by another exemplary reference, hereafter

`
`typical weir.

`
`Figure 3 Illustration of Weir 3-Dimensionality3
`
`31. In general, weirs have been classified as simple or complex; what they have in common is
`
`a boundary that separates a body of liquid from the targeted discharge. Furthermore, simple weirs’
`
`vertical walls may cause the liquid to overflow along edges along the boundary. In complex weirs,
`
`the edge changes along the horizontal component; in other words, complex weirs have divided
`
`horizontal component sections, and when the vertical component exceeds the edge, it is a separator
`
`of the segments of the edge. This is shown in Figure 4, below, excepted from the
`
`Openchannelflow.com website.
`
`32. Complex weirs can be composed of consecutive orifices (circular weirs), slots (both
`
`vertical and horizontal), holes, notches, or "saw-tooth" edges deployed along the horizontal edge
`
`of a boundary; these may be contiguous or separated by a preselected distance. In another example,
`
`from the Nano-Reef.com website, Figure 5 shows an example of a weir using slots; moreover,
`
`circular weirs are variant of these slotted holes.

`7 below, from the thesis paper by Armond Dudley Barefoot, shows still another example of a
`
`circular hole operating as a weir. Similarly, Figure 8 shows a series of circular weirs. It is of note
`
`that weirs vertical components may end at the fluid level or may be submerged.

`b) “plenum”
`
`34. The term “plenum” appears in claims 1, 5, 6, 10, 11, 14 in the ‘457 Patent and claims 1, 5,
`
`6, and 10 of the ‘446 Patent. The term “plenum” means “a structure for dispensing liquid.”
`
`35. The term “plenum” also appears in the ‘457 Patent specification and drawings at: Abstract;
`
`FIGS. 1, 5, 6, 11, 13; Column/line – 3:1-6, 3:13-19, 3:52-56, 4:17-26, 4:27-32, 4:55-58, 6:45, 6:49-
`
`54, 7:12-19, 8:22, 9:7-24, 9:38-42, 10:21-25, and 10:66-11:3. The term appears in the ‘446 Patent
`
`specification and drawings at: Abstract; FIGS. 1, 5, 6, 11, 13; Column/line – 3:1-6, 3:13-19, 3:52-
`
`56, 4:17-26, 4:27-32, 4:55-58, 6:45, 6:49-54, 7:12-19, 8:22, 9:10-27, 9:42-45, and 10:26-29.
`
`36. In tanks for handling liquids, generally, a plenum is a structure having a space to collect
`
`incoming liquid for the subsequent dispensing of the liquid to various locations. As described in
`
`the specification and shown in FIGS. 1, 7, 8, and 9 of the ‘457 Patent and ‘446 Patent, the plenum
`
`is a structure that collects the incoming liquid (e.g., dielectric fluid) and dispenses the liquid (e.g.,
`
`dielectric fluid) substantially uniformly upwardly through each appliance slot.
`
`37. One function of the plenum is to change the liquid flow from the incoming liquid velocity
`
`to discharge velocity based on the inlet and outlet cross-sectional areas. As shown, for example,
`
`in FIG. 8 of the ‘457 Patent, the liquid (e.g., dielectric fluid) is constrained to collect and then exit
`
`through predesigned outlets such as orifices or nozzles. As shown, for example, in FIG. 10 of the
`
`‘457 Patent, the outlets are located and sized to direct the flow of liquid towards various locations.
`
`A definition is considered, which is “plenum”: the whole of space regarded as being filled with
`
`matter (opposed to vacuum,) Merriam-Webster.9
`
`
`9 “Plenum - a space or all space every part of which is full of matter” Merriam-Webster's Unabridged
`Dictionary, Merriam-Webster, https://unabridged.merriam-webster.com/unabridged/plenum. Accessed May 4,
`2021.

`

`38. Additionally, a POSA would understand that a plenum will include non-chamber structures
`
`for dispensing a liquid such as a network of pipes used to collect and then dispense liquid as
`
`illustrated in Figure 9.

`
`
`X. Two Disputed Claim Terms/Phrases:
` “a weir … having an overflow lip adapted to facilitate substantially uniform
`
`recovery”
`
` “a weir … adapted to facilitate substantially uniform recovery”
`
`39. The first term/phrase above -- “a weir … having an overflow lip adapted to facilitate
`
`substantially uniform recovery” -- appears in the ‘457 Patent claims 1, 5, 6, 10.This first
`
`term/phrase also appears in the specification and drawings in the ‘457 Patent Specification at:
`
`Abstract, FIGS. 1, 5, 6, 11, 12, 13; Column/line – 2:59-61, 3:1-6, 3:13-19, 3:23-25, 3:39-63, 4:30-
`
`34, 4:57-58, 8:22, 9:7-24, 9:37-46, 10:20-29; and 10:65-11:3.

`

`

`40. Each of the words in the above first term/phrase has a plain and ordinary meaning that a
`
`POSA will easily comprehend. The term “weir” has the meaning discussed above, i.e., an overflow
`
`structure or barrier that determines the level of a liquid. Obviously, from the context, the “overflow
`
`lip” is part of the weir. The overflow lip is the part of the weir over which liquid flows. Therefore,
`
`a person having ordinary skill in the art will understand that “a weir … having an overflow lip”
`
`means an “overflow edge or boundary of the weir.”
`
`41. The term “adapted to” simply means “suitable for” or “capable of.” The term “facilitate”
`
`means “to make easier” or “to help bring about.”10
`
`42. So the above phrase simply means “a weir…having an overflow edge or boundary capable
`
`of easing or helping to bring about the substantially uniform recovery (of the dielectric fluid
`
`flowing through each appliance slot).” A POSA should have no problem understanding the
`
`meaning of this phrase.
`
`43. The second term/phrase above --“a weir … adapted to facilitate substantially uniform
`
`recovery" appears in claims 1 and 6 of the ‘446 Patent.
`
`44. The term also appears throughout the specifications of both of the patents-in-suit, for
`
`example, in the ‘457 Patent specification and drawings at: Abstract, FIGS. 5, 6, 11, 12, 13;
`
`Column/line – 3:1-6, 3:16-19, 3:23-25, 3:39-63, 4:30-34, 4:57-58, 8:22, 9:7-24, 9:37-46, 10:20-
`
`29, and 10:65-11:3, and in the ‘446 Patent specification and claims at: Abstract; FIGS. 5, 6, 11,
`
`12, 13; Column/line – 3:3-8, 3:18-21, 3:25-27, 3:38-58, 4:29-34, 4:57-60, 8:25, 9:10-27, 9:42-45,
`
`and 10:26-29.

`

`45. Similar to the above, each of the words in the above second term/phrase has a plain and
`
`ordinary meaning that a POSA will easily comprehend. As before, the term “weir” has the
`
`meaning discussed above, i.e., an overflow structure or barrier that determines the level of a liquid.
`
`46. As before, the term “adapted to” simply means “suitable for” or “capable of.” And as
`
`before, the term “facilitate” means “to make easier” or “to help bring about.”
`
`47. So the above second disputed term/phrase simply means “a weir… capable of easing or
`
`helping to bring about the substantially uniform recovery (of the dielectric fluid flowing through
`
`each appliance slot).” Again, in my opinion, a POSA should have no problem understanding the
`
`meaning of this phrase.
`
`48. I am informed that Immersion has taken the position that the above two terms/phrases
`
`found in various claims of the two patents-in-suit render the two patents to be indefinite.
`
`49. I understand that a patent is indefinite if its claims, read in light of the specification and the
`
`prosecution history, fail to inform, with reasonable certainty, those skilled in the art about the scope
`
`of the invention. It is my opinion that there is nothing in the above two phrases that fail to inform
`
`a POSA about the scope of the claimed invention with reasonable certainty. Indeed, as
`
`demonstrated above, the proper meaning of these two phrases is simple to understand.
