Before NEWMAN, LOURIE, and TARANTO, Circuit Judges. LOURIE, Circuit Judge. Power Probe Group, Inc. (“Power Probe”) appeals from a decision of the United States District Court for the Dis- trict of Nevada denying a preliminary injunction against further sales of Innova Electronics Corporation’s (“Innova”) Powercheck #5420 device (the “Accused Product”). See Power Probe Grp., Inc. v. Innova Elecs. Corp., No. 21-cv- 332, 2021 WL 4484571 (D. Nev. Sept. 15, 2021) (“Deci- sion”). Because the district court erred in its preliminary claim construction, we vacate its decision denying a prelim- inary injunction and remand for further proceedings con- sistent with this opinion. BACKGROUND Power Probe owns U.S. Patent 7,184,899 (the “’899 pa- tent”). The patent is directed to an electrical test device having multi-meter functionality that measures a plurality of parameters. Independent claim 1 reads in part as fol- lows. 1. An electrical test device having multimeter functionality and being adapted to provide current sourcing to an electrical system for selective meas- urement of a plurality of parameters thereof in at least one of powered and unpowered states, the electrical test device comprising: .... ’899 patent at col. 11 ll. 29–51 (emphasis added). Depend- ent claim 3 includes additional components used in “detect- ing continuity in the electrical system.” Id. at col. 12 ll. 2– Case: 21-2354 Document: 54 Page: 3 Filed: 04/12/2022

POWER PROBE GROUP, INC. v. 3 INNOVA ELECTRONICS CORPORATION

3. Dependent claim 10 includes an additional limitation “wherein the parameters measurable by the test device in- clude at least one of circuit continuity, resistance, voltage, current, load impedance and frequency.” Id. at col. 12 ll. 21–24. Dependent claim 12 further includes “a pair of sig- nal lamps connected to the processor and configured to il- luminate in response to continuity measurement.” Id. at col. 12 ll. 52–54. Power Probe sued Innova in the district court, alleging that the Accused Product infringes claims 1, 2, 5–10, 12, and 13 of the ’899 patent. Additionally, Power Probe moved for a preliminary injunction against further sales of the Ac- cused Product during the pendency of the litigation. In ruling on Power Probe’s motion for a preliminary in- junction, the district court first held that “measurement” in the claims means determining “a numerical or quantita- tive value associated with and indicative of the parameter under test.” Decision at *4. The court then conducted a preliminary claim construction and held that a “plurality of parameters” means “at least two parameters.” Id. at *5. The court then noted that the Accused Product measures only one parameter, voltage. The district court added that “continuity” is “the pres- ence of a complete path for current flow” and cannot be di- rectly measured but can be detected as either existing or not. Id. Based on this determination, the court found that the Accused Product detects, but does not measure, conti- nuity. Accordingly, the court denied Power Probe’s motion for a preliminary injunction because it failed to establish a likelihood of success in proving infringement. It did not evaluate the other factors necessary for the grant of a pre- liminary injunction. Power Probe appealed the district court’s denial of its preliminary injunction motion. We have jurisdiction pur- suant to 28 U.S.C. §1295(a)(1). Case: 21-2354 Document: 54 Page: 4 Filed: 04/12/2022

DISCUSSION “A plaintiff seeking a preliminary injunction must es- tablish that he is likely to succeed on the merits, that he is likely to suffer irreparable harm in the absence of prelimi- nary relief, that the balance of equities tips in his favor, and that an injunction is in the public interest.” Winter v. Natural Res. Def. Council, Inc., 555 U.S. 7, 20 (2008). An accused infringer can defeat a showing of likelihood of suc- cess on the merits by demonstrating a substantial question of validity or infringement. See Aria Diagnostics, Inc. v. Sequenom, Inc., 726 F.3d 1296, 1304 (Fed. Cir. 2013). A preliminary injunction is “an extraordinary remedy that may only be awarded upon a clear showing that the plain- tiff is entitled to such relief.” Winter, 555 U.S. at 22. “The grant, denial, or modification of a preliminary in- junction . . . is not unique to patent law, so this court ap- plies the law of the regional circuit when reviewing and interpreting such a decision.” Aevoe Corp. v. AE Tech Co., 727 F.3d 1375, 1381 (Fed. Cir. 2013). The Ninth Circuit “review[s] the district court’s grant of a preliminary injunc- tion for abuse of discretion.” Valle del Sol Inc. v. Whiting, 732 F.3d 1006, 1014 (9th Cir. 2013). We have “built a body of precedent applying the[] gen- eral [preliminary injunction] considerations to a large number of factually variant patent cases, and [] give domi- nant effect to [our] precedent insofar as it reflects consid- erations specific to patent issues.” Mikohn Gaming Corp. v. Acres Gaming, Inc., 165 F.3d 891, 894 (Fed. Cir. 1998). Claim construction is ultimately an issue of law, which we review de novo. Shire Dev., LLC v. Watson Pharms., Inc., 787 F.3d 1359, 1364 (Fed. Cir. 2015). We review de novo the district court’s findings based on evidence “intrin- sic to the patent,” which is all that is at issue here. Teva Pharms. USA, Inc. v. Sandoz, Inc., 135 S. Ct. 831, 841 (2015). Case: 21-2354 Document: 54 Page: 5 Filed: 04/12/2022

POWER PROBE GROUP, INC. v. 5 INNOVA ELECTRONICS CORPORATION

Power Probe argues that the district court erred in holding that “continuity” is a parameter not capable of measurement. It asserts that the ’899 patent’s specifica- tion and the plain language of claims 10 and 12 teach that continuity is capable of measurement. Innova responds that Power Probe forfeited its argu- ments because its argument on claim construction on ap- peal is inconsistent with its argument that there need not be any claim construction at the district court. On the mer- its, Innova asserts that the court did not construe “continu- ity” as a matter of law as “a parameter incapable of measurement,” but instead found as a matter of fact that “continuity is not capable of measurement as defined be- cause it cannot be quantified.” Appellee’s Br. at 16. It adds that the court properly found that resistance can be meas- ured, and from that measurement, continuity can be deter- mined as either existing or not. We disagree with Innova’s forfeiture argument. In- nova accuses Power Probe of advancing inconsistent argu- ments as to the meaning of “continuity.” Specifically, Innova asserts that Power Probe argues at the district court that “continuity measurement” should be afforded its plain and ordinary meaning, but that Power Probe seeks a claim construction on appeal. Power Probe responds that its positions are consistent and that the plain and ordinary meaning of “continuity measurement” is determining the measured value associated with circuit continuity. Power Probe is correct. Following the district court’s denial of its preliminary injunction motion, Power Probe filed a claim construction brief. In that brief, Power Probe argues that no construction is needed because the plain and ordinary meaning of “continuity measurement” is “de- termining a measured value associated with circuit conti- nuity.” Power Probe Grp., Inc. v. Innova Elecs. Corp., No. 21-cv-332, ECF No. 107 at 18–22 (D. Nev. Sept. 30, 2021). On appeal, Power Probe argues that the district court erred Case: 21-2354 Document: 54 Page: 6 Filed: 04/12/2022

in not applying the proper plain and ordinary meaning of “continuity measurement” because continuity is capable of measurement. See, e.g., Appellant’s Br. at 42–43. Power Probe’s claim construction brief is not on the record before us because it was filed after the court denied Power Probe’s preliminary injunction motion. Thus, we need not enter- tain Innova’s forfeiture argument. However, even if we do consider Innova’s argument and take judicial notice of Power Probe’s brief, 1 we find that while Power Probe’s statements in its claim construction brief and on appeal are not verbatim identical, neither are they fundamentally in- consistent. For these reasons, we find that Power Probe has not forfeited its “continuity” arguments. Turning to the merits, we also agree with Power Probe. As a matter of lexicography, the ’899 patent’s specification defines “parameters measurable by the electrical test de- vice” as including “circuit continuity.” ’899 patent at col. 9 ll. 9–11. Furthermore, claim 10 specifies that one “param- eter[] measurable by the test device” is “circuit continuity.” Id. at col. 12 ll. 22–23. Lastly, claim 12 requires “continuity measurement.” Id. at col. 12 ll. 53–54. These references show that the inventor used the term continuity as a meas- urable quantity. Although claim 3 recites “detecting conti- nuity,” id. at col. 12 l. 2, the district court wrongly assumed that detecting continuity and measuring continuity are mutually exclusive. This case is similar to Trustees of Columbia University, where we considered a situation where an independent claim of a patent was directed to “[a] method for detecting anomalous program executions.” Trustees of Columbia Univ. in City of New York v. Symantec Corp., 811 F.3d 1359, 1369 (Fed. Cir. 2016). There, “[t]he district court

construed ‘anomalous’ to mean ‘[d]eviation/deviating from a model of typical, attack-free computer system usage’” and later clarified that the model “only uses attack-free data.” Id. at 1369–70. However, on appeal, we recognized that “[t]he claims themselves show that the model can be built with both attack-free and attack data.” Id. at 1370 (empha- sis added). That is, in Trustees of Columbia University, we recognized that some dependent claims further limited the claimed scope to “attack-free” data while other dependent claims limited the claim scope to “attack data.” We con- cluded that “because the dependent claims [in] patents are presumed to be narrower than the independent claims on which they depend, ‘anomalous’ cannot be read to limit the type of data used to model [] only attack-free data in the independent claims in the absence of other evidence rebut- ting the presumption.” Id. Similarly, here, the district court improperly construed independent claim 1 to exclude “continuity” limitations included in dependent claims 10 and 12 that describe “continuity” as measurable. Inde- pendent and dependent claims must if possible be inter- preted to be consistent with each other, so continuity must be construed to be measurable. We thus hold that the court erred in construing “continuity” as a parameter that is not measurable. CONCLUSION We have considered Innova’s remaining arguments but find them unpersuasive. For the foregoing reasons, we va- cate the district court’s decision denying a preliminary in- junction and remand for further proceedings regarding whether Power Probe satisfied the requirements for a pre- liminary injunction. VACATED AND REMANDED COSTS Costs are awarded to Power Probe.
