Before PROST, TARANTO, and CHEN, Circuit Judges. 

PROST, Circuit Judge.

Ultravision Technologies, LLC (“Ultravision”) sued 

Shenzhen Absen Optoelectronic Co., Ltd. and Absen Inc. 

(collectively, “Absen” or “Appellees”) for patent infringement. After claim construction, Ultravision stipulated to 

noninfringement of claims 14 and 15 of U.S. Patent 

No. 9,047,791 (“the ’791 patent”) and claims 15 and 17 of 

U.S. Patent No. 9,666,105 (“the ’105 patent”).1 A jury later

returned a verdict of noninfringement and invalidity of

claim 9 of U.S. Patent No. 9,916,782 (“the ’782 patent”). 

The district court subsequently denied Ultravision’s motion for a new trial based on the ’782 patent claim construction. Ultravision appeals, arguing that the stipulated 

judgment and the judgment entered based on the jury’s 

verdict should be overturned based on two claim-construction errors. Because the district court correctly construed 

both claim terms, we affirm the final judgment. 

1 Ultravision also stipulated to noninfringement of 

claims 12–13 and 19–20 of the ’791 patent, J.A. 102, but 

those claims are no longer at issue here because we affirmed the Patent Trial and Appeal Board’s (“Board”) unpatentability determinations on those claims. Ultravision

2023).

ULTRAVISION TECHNOLOGIES, LLC v. GOVISION, LLC 3

BACKGROUND

I 

Claim 9 of the ’782 patent, which depends from claim 

1, was the only claim asserted at trial and is therefore the 

only claim at issue here. However, the only challenged 

term, “waterproof,” appears in claim 1. Claim 1 of the 

’782 patent recites in relevant part: “wherein the modular 

display panel is sealed to be waterproof.” ’782 patent claim 

1 (emphasis added). 

At the district court, Ultravision argued that “waterproof” means “preventing water from entering the interior 

of the panel when exposed to weather,” and Absen argued 

that it means “preventing water from entering (the panel).” 

Ultravision Techs., LLC v. Govision LLC, No. 2:18-cv00100-JRG-RSP, 2020 WL 12570811, at *9–10 (E.D. Tex. 

Sept. 30, 2020) (“Claim Construction Order”). Absen also 

argued that Ultravision’s construction rendered the claims 

indefinite. Id. After considering the parties’ arguments, 

the district court ultimately construed “waterproof” as “ingress protection (IP) rating of IP 65 or higher.” Id. at *12. 

Under this “rating of IP 65 or higher” construction, the 

jury returned a verdict of noninfringement and invalidity

of claim 9. J.A. 5137–38. The district court entered judgment according to the verdict, J.A. 101–02, and denied Ultravision’s motion for a new trial, J.A. 100. 

II

The ’791 and ’105 patents, also related to display modules, claim modification kits to convert existing signs into 

electronic signs. Ultravision stipulated to noninfringement 

of claims 14 and 15 of the ’791 patent and claims 15 and 17 

of the ’105 patent based on the construction of “display 

module.” Ultravision agrees that claim 12 of the 

Case: 22-1098 Document: 42 Page: 3 Filed: 02/23/2023
4 ULTRAVISION TECHNOLOGIES, LLC v. GOVISION, LLC

’791 patent, which claims 14 and 15 depend from, is exemplary for purposes of this claim construction dispute2: 

A modification kit for converting an existing signage mounting structure to an electronic sign comprising:

a plurality of display modules; 

a plurality of sign sections each having a front portion and a rear portion, the front portion defining 

at least two vertical columns of bays that span and 

define a height of the sign, each bay configured to 

receive one of the display modules, the rear portion 

configured to be attached to a beam surface of the 

existing signage structure to allow most of a rear 

surface of the rear portion to be exposed for servicing; and

a plurality of power routing systems each including 

at least one node associated with each sign section 

with a plurality of individual power extensions 

each extending from one node to one of the bays.

’791 patent claim 12 (emphasis added). 

Ultravision argued to the district court that the claim 

term “display module” should be given its plain and ordinary meaning. Claim Construction Order, 2020 WL 

12570811, at *31. Absen argued that it should be construed to mean “a sealed display module having a pair of 

LED panels operatively coupled to a daughter board.” Id. 

The district court adopted Absen’s construction in part, 

construing the term to mean “module having a pair of LED 

2 We cite to the ’791 patent throughout because Ultravision has not separately argued or suggested that any 

distinction from the ’105 patent impacts the construction of 

“display module.” 

Case: 22-1098 Document: 42 Page: 4 Filed: 02/23/2023
ULTRAVISION TECHNOLOGIES, LLC v. GOVISION, LLC 5

display panels operatively coupled to a daughter board.” 

Id. at *33 

Ultravision stipulated to noninfringement of claims 14 

and 15 of the ’791 patent and claims 15 and 17 of the 

’105 patent under this construction of “display module” 

and, after the jury trial on the ’782 patent, the district court 

entered final judgment accordingly. J.A. 102. 

III

Ultravision appeals the final judgment as it relates to 

the ’791, ’105, and ’782 patents.3 It bases this challenge

only on its contention that the claim constructions of “waterproof” and “display modules” were erroneous. Ultravision also challenges the denial of its motion for a new 

trial on the ’782 patent. That challenge rests on its claim 

construction argument and its position that the district 

court erroneously found that Ultravision was not prejudiced by the construction because it concluded that the result would have been the same under Ultravision’s 

proposed construction. 

We have jurisdiction under 28 U.S.C. § 1295(a)(1). 

DISCUSSION

In general, claim terms are construed based on their 

ordinary meaning to a person of skill in the art who has 

read the entire specification and all the claims. Phillips v. 

3 Ultravision also appealed the “waterproof” construction as it related to claim 22 of U.S. Patent 

No. 9,978,294—the jury also returned a verdict of noninfringement and invalidity on that claim—but we have since 

affirmed the Board’s determination that claim 22 of the 

’294 patent is unpatentable. See Ultravision Techs., LLC 

v. Glux Visual Effects Tech (Shenzhen) Co., No. 2022-1342, 

2023 WL 177689, at *1 (Fed. Cir. Jan. 13, 2023). Thus, that 

aspect of the appeal is now moot. 

Case: 22-1098 Document: 42 Page: 5 Filed: 02/23/2023
6 ULTRAVISION TECHNOLOGIES, LLC v. GOVISION, LLC

AWH Corp., 415 F.3d 1303, 1313 (Fed. Cir. 2005) (en banc). 

The specification may also indicate, either expressly or by 

implication, that the patentee uniquely defined a claim 

term. Trs. of Columbia Univ. v. Symantec Corp., 811 F.3d 

1359, 1363 (Fed. Cir. 2016). Further, the specification’s 

emphasis of a particular feature’s importance to the invention can indicate “what the patentee had claimed and disclaimed.” See SafeTCare Mfg., Inc. v. Tele-Made, Inc., 497 

F.3d 1262, 1269–70 (Fed. Cir. 2007). In addition, the prosecution history sheds light on a term’s meaning because it 

“provides evidence of how the PTO and the inventor understood the patent.” Phillips, 415 F.3d at 1317. “We review 

claim construction based on intrinsic evidence de novo and 

review any findings of fact regarding extrinsic evidence for 

clear error.” SpeedTrack, Inc. v. Amazon.com, 998 F.3d 

1373, 1378 (Fed. Cir. 2021) (citing Teva Pharms. USA, Inc. 

v. Sandoz, Inc., 574 U.S. 318, 331–32 (2015)). 

I 

First, we address the construction of “waterproof” as it 

relates to claim 9 of the ’782 patent. For the reasons below, 

we agree with the district court’s construction: “ingress 

protection (IP) rating of IP 65 or higher.” As a result, we 

affirm the final judgment of invalidity and noninfringement of claim 9. We likewise affirm the district court’s denial of Ultravision’s motion for a new trial. Because the 

claim construction is correct, we need not (and do not) 

reach the issue of whether the district court was correct 

that Ultravision was not prejudiced by the construction. 

The ’782 specification uses “waterproof” as a term of 

degree. See, e.g., ’782 patent col. 4 ll. 65–66 (“These panels 

are completely waterproof against submersion in up to 3 

feet of water.” (emphasis added)). And it repeatedly uses 

ingress protection (“IP”) ratings to describe the degree of 

Case: 22-1098 Document: 42 Page: 6 Filed: 02/23/2023
ULTRAVISION TECHNOLOGIES, LLC v. GOVISION, LLC 7

protection from water.4 ’782 patent col. 7 ll. 42–52 (“In the 

present example, the housing 220 is sealed to prevent water from entering the housing. For example, the housing 

220 may be sealed to have an ingress protection (IP) rating 

such as IP 67, which defines a level of protection against 

both solid particles and liquid. . . . In other embodiments, 

the housing may be sealed to have an IP rating of IP 65 or 

higher, e.g. IP 65, IP 66, IP 67, or IP 68.”); id. at col 4 l. 61–

col. 5 l. 3 (“In certain embodiments, the display is IP 67 

rated and therefore waterproof and corrosion resistant. . . . In lower-cost embodiments where weatherproofing is not as significant, the panels can have an IP 65 

or IP 66 rating.”). An IP rating of 65 is the lowest value 

discussed as providing protection from water; it is the lowest IP rating mentioned in the specification. 

The district court based its construction on an evaluation of the intrinsic record and relevant prosecution history. Further, the court reasoned that Ultravision’s 

proposed construction, preventing water from entering the 

interior of the panel when exposed to weather, “would 

change the claim requirement of ‘waterproof’ to ‘weatherproof’” and it “would not provide any bounds for the scope 

of the claims.” Claim Construction Order, 2020 WL 

12570811, at *11. As for Absen’s proposed construction,

preventing water from entering (the panel), the district 

court rejected it because it “require[s] levels of protection 

against every possible condition, including conditions that 

the panels would never be expected to operate in,” which 

was inconsistent with the specification’s description of “different levels of waterproof protection.” Id. at *12. 

The intrinsic record supports the district court’s construction. As noted above, the specification discusses 

4 Everyone agrees that IP ratings are standard ratings that reflect resistance to water and dust. Appellant’s 

Br. 14 n.5; Appellees’ Br. 7. 

Case: 22-1098 Document: 42 Page: 7 Filed: 02/23/2023
8 ULTRAVISION TECHNOLOGIES, LLC v. GOVISION, LLC

“waterproof” as varying in degree and consistently uses IP 

ratings of 65 or higher to describe the level of protection 

from water. Further, during prosecution the patentee explained that the clause “when the panel is immersed in water,” which appeared in a subsequently amended claim, 

“describes the degree to which the panel is ‘sealed to be waterproof.’” J.A. 3502. That clause was then amended to 

“the panel compris[es] an ingress protection (IP) rating of 

IP 67 or IP 68”—indicating that the patentee also understood “waterproof” to vary in degree and that IP ratings describe that degree. J.A. 3502–03. Thus, the construction 

of “waterproof” as “ingress protection (IP) rating of IP 65 or 

higher” appropriately captures the term’s meaning as used 

in the ’782 patent. 

Ultravision’s arguments to the contrary are unpersuasive. 

First, Ultravision relies on the doctrine of claim differentiation to argue that claim 6’s recitation of “wherein the 

modular display panel comprises an ingress protection (IP) 

rating of IP 65, IP 66, IP 67, or IP 68” precludes a construction where IP ratings are present in the independent claim

by virtue of the “waterproof” construction. But the construction does not render the scope of claim 6 and the scope 

of claim 1 equivalent. Instead, the construction of IP 65 or 

higher also includes an IP rating of 69, a value not claimed 

in claim 6. Thus, claim 6 has a narrower scope than claim 

1 even under the challenged construction. Since the claim 

construction does not generate any redundancy, the doctrine of claim differentiation does not apply here. See Apple, Inc. v. Ameranth, Inc., 842 F.3d 1229, 1238 (Fed. Cir. 

2016) (“This court has declined to apply the doctrine of 

claim differentiation where the claims are not otherwise 

identical in scope.” (cleaned up)). 

We are further unpersuaded by Ultravision’s related 

argument that claim differentiation applies because IP 69 

can’t be included in the construction of “waterproof.” The 

Case: 22-1098 Document: 42 Page: 8 Filed: 02/23/2023
ULTRAVISION TECHNOLOGIES, LLC v. GOVISION, LLC 9

specification’s failure, however, to explicitly call out an IP 

rating of 69 here doesn’t serve to exclude it from the meaning of “waterproof.” The specification emphasizes the desirability of protecting displays from water and an IP 

rating of 69 would provide protection from water under 

more conditions. 

Regardless, “[c]laim differentiation is a guide, not a 

rigid rule,” and does not alter a construction otherwise 

compelled by the intrinsic record. Wi-LAN USA, Inc. v. Apple Inc., 830 F.3d 1374, 1391 (Fed. Cir. 2016). As discussed 

above, the intrinsic record here indicates that the scope the

patentee ascribed to the relative term “waterproof” is an IP 

rating of 65 or higher. That the patentee also decided to 

specifically claim a particular subset of IP values—i.e., indicate the degree of waterproofing with more particularity—in claim 6 does not overcome that conclusion in these 

circumstances. 

Next, Ultravision argues that the construction is incorrect because “waterproof” is never expressly defined as “IP 

65 or higher” in the specification. Appellant’s Br. 30–32. 

This argument misses the point: “waterproof” must be construed based on consideration of the claims and the specification as a whole. The specification did not need to, itself, 

provide an explicit definition; the context and use of “waterproof” in the claims and specification overall support the 

construction reached. See Trs. of Columbia Univ., 811 F.3d 

at 1363 (rejecting an argument that explicit redefinition is 

required and noting that “[t]he only meaning that matters 

in claim construction is the meaning in the context of the 

patent.”). 

Ultravision’s argument that the district court improperly relied on the prosecution history because the patentee’s statements don’t amount to clear and 

unmistakable disclaimer is similarly unpersuasive. Appellant’s Br. 32. The prosecution history is relevant for more 

than an evaluation of disclaimer—it provides additional 

Case: 22-1098 Document: 42 Page: 9 Filed: 02/23/2023
10 ULTRAVISION TECHNOLOGIES, LLC v. GOVISION, LLC

context for evaluating how the term would be understood 

and how it was used in the patent. Iridescent Networks, 

Inc. v. AT&T Mobility, LLC, 933 F.3d 1345, 1353 (Fed. Cir. 

2019) (rejecting a similar argument when construing “high 

quality of service connection” because “where there is no 

clear ordinary and customary meaning of a coined term of 

degree, we may look to the prosecution history for guidance 

without having to first find a clear and unmistakable disavowal.”). Here, the patentee’s discussion of “the degree to 

which the panel is ‘sealed to be waterproof’” during prosecution, J.A. 3502, only bolsters the district court’s conclusion about the meaning of “waterproof” based on the 

specification itself. 

Finally, we need not look to extrinsic evidence here because the intrinsic record well supports the claim construction of “waterproof.” Seabed Geosolutions (US) Inc. v. 

Magseis FF LLC, 8 F.4th 1285, 1287 (Fed. Cir. 2021) (“If 

the meaning of a claim term is clear from the intrinsic evidence, there is no reason to resort to extrinsic evidence.”). 

However, even if we were to look to extrinsic evidence for 

additional context, Ultravision’s expert testimony would 

not counsel against the construction reached. As the district court pointed out, Ultravision’s expert also acknowledged that “[o]ne useful reference that a person of ordinary 

skill in the art would be familiar with when dealing with 

waterproofing is the Ingress Protection (IP) standard.” 

Claim Construction Order, 2020 WL 12570811, at *10 

(quoting J.A. 1986). 

Thus, we affirm the construction of “waterproof” as “ingress protection (IP) rating of IP 65 or higher.” And, because Ultravision challenges the final judgment of 

invalidity and noninfringement of claim 9 of the ’782 patent

based only on this construction, we affirm the judgment. 

II

Ultravision also challenges the district court’s construction of “display module”—it stipulated to 

Case: 22-1098 Document: 42 Page: 10 Filed: 02/23/2023
ULTRAVISION TECHNOLOGIES, LLC v. GOVISION, LLC 11

noninfringement of claims 14 and 15 of the ’791 patent and 

claims 15 and 17 of the ’105 based on the construction. We 

also reject this challenge because we agree with the district 

court’s construction of “display module” as “module having 

a pair of LED display panels operatively coupled to a 

daughter board.” 

The court based its construction on its conclusion that 

“the patentee indicated that the daughter board and pair 

of LED panels are ‘important and unique feature of the present invention,’” Claim Construction Order, 2020 WL 

12570811, at *33 (citing ’791 patent col. 34 ll. 41–63), and 

that “every disclosed embodiment includes a pair of LED 

panels operatively coupled to a daughter board,” id. (citing 

’791 patent col. 25 ll. 30–33, col. 27 ll. 1–7, col. 38 ll. 9–14, 

col. 43 ll. 62–67). 

We agree with the district court’s evaluation. The specification describes that a display module includes a single 

daughter board connected to two display panels. Specifically, it explains that “each display module 14 also includes 

a centrally disposed daughter board 20 which handles the 

transfer of data between each of the display panel assemblies 14L and 14R respectively.” ’791 patent col. 34 

ll. 41–45; see also id. at col. 25 ll. 30–33 (“Each individual 

display panel module . . . includes dual LED display panels.” (emphasis added)), col. 27 ll. 2–6 (“[W]ith the aid of an 

interconnecting daughter board . . . a significant reduction 

is achieved as only a single DC/DC converter is utilized to 

power the two optimum sized LED panels . . . .” (emphasis 

added)), col. 43 ll. 63–66 (describing the figure as showing 

that “display module 14 generally includes the daughter 

board 20 and its associated LED display panel boards 14L 

and 14R respectively”). Additionally, the specification 

states that this arrangement of a single daughter board 

connected to two LED panels “is an important and unique 

feature of the present invention.” Id. at col. 34 ll. 50–52. 

Case: 22-1098 Document: 42 Page: 11 Filed: 02/23/2023
12 ULTRAVISION TECHNOLOGIES, LLC v. GOVISION, LLC

Where the specification repeatedly emphasizes a feature as unique or distinguishing, we have found that indicative of “what the patentee has claimed and disclaimed.” 

SafeTCare Mfg., 497 F.3d at 1270. As discussed above, the 

specification can impart meaning explicitly or implicitly. 

Here, the specification is clear that the invention’s “display 

module” has a pair of LED display panels operatively coupled to a daughter board. Thus, the disclosure indicates 

that a single LED panel coupled to the daughter board falls 

outside the claimed scope of “display module.” 

Ultravision is incorrect that the specification described 

the center mounting arrangement as unique instead of the 

pair of LED panels coupled to a daughter board. See Appellant’s Br. 51. They are the same feature. The “important and unique” center mounting arrangement is 

described as involving a pair of LED displays with the 

daughter board located centrally between them; the specification explains that the arrangement is beneficial because it enables two LED panels to be powered and 

controlled by a single daughter board. See ’791 patent 

col. 34 ll. 41–58. 

Further, Ultravision primarily relies on a single sentence in the specification to argue that the district court’s 

construction improperly excludes a disclosed single-panel 

embodiment. But the specification’s statement that “[i]n 

one embodiment, the at least one LED board includes two 

LED boards disposed in a side-by-side arrangement along 

the X-axis,” ’791 patent col. 2 ll. 27–29, does not indicate 

that the claimed scope of “display module” captures an embodiment with a single LED panel coupled to a daughter 

board. First, it is not clear that “one LED board” is even 

synonymous with one LED panel. Further, the description 

of a single embodiment where a first aspect of the display 

module comprises “at least one LED board” (which clearly 

includes two LED boards) is not enough to overcome the 

specification’s description of a pair of LED panels coupled 

Case: 22-1098 Document: 42 Page: 12 Filed: 02/23/2023
ULTRAVISION TECHNOLOGIES, LLC v. GOVISION, LLC 13

to a daughter board as important and unique to the invention. 

In sum, we affirm the district court’s construction of 

“display module” and affirm the stipulated judgment of 

noninfringement of claims 14 and 15 of the ’791 patent and 

claims 15 and 17 of the ’105 patent under that construction. 

CONCLUSION

We have considered Ultravision’s other arguments and 

find them unpersuasive. Because the district court correctly construed “waterproof” and “display module,” we affirm.
