Case No. 2:23-CV-0306-JRG-RSP

MEMORANDUM ORDER

Before the Court is Defendant’s Motion to Stay Pending Inter Partes Review. (Dkt. 

No. 69.) For the reasons provided below, Defendant’s Motion is DENIED.

I. BACKGROUND

Plaintiff FlatFrog and Defendant Chemtronics are both manufacturers of large touch 

screens that Plaintiff contends are covered by the Asserted Patents. (Opp. at 3-4.) The parties 

both manufacture these screens for Samsung to integrate into Samsung’s own products. (Id.) 

Plaintiff contends that over the period from 2021 to 2023 Defendant has largely overtaken 

Plaintiff in providing the touch screens to Samsung, whereas Plaintiff previously held a dominant 

position. (Id.)

On April 22, 2024, the PTAB instituted IPRs against all three asserted patents, covering 

all asserted claims. (Mot. at 1.) This puts Final Written Decisions expected around April 2025, 

the same month as trial is scheduled in the instant case. (Id. at 1.) 

II. LEGAL STANDARD

“The party seeking a stay bears the burden of showing that such a course is appropriate.” Peloton 

Interactive, Inc. v. Flywheel Sports, Inc., No. 218-cv-390-RWS-RSP, 2019 WL 3826051, at *1 (E.D. Tex. 

Aug. 14, 2019) (quoting Realtime Data, LLC v. Hewlett Packard Enter. Co., No. 6:16-cv-86-RWS-JDL,

2017 WL 3712916, at *3 (E.D. Tex. Feb. 3, 2017)); accord Landis v. N. Am. Co., 299 U.S. 248, 255 

(1936). “The decision of whether to extend a stay falls solely within the court’s inherent power to control 

its docket.” Personal Audio LLC v. Google, Inc., 230 F. Supp. 3d 623, 626 (E.D. Tex. 2017) (citing 

ThinkOptics, Inc. v. Nintendo, No. 6:11-cv-455-LED, 2014 WL 4477400, at *1 (E.D. Tex. Feb. 27, 

2014)); accord Clinton v. Jones, 520 U.S. 681, 706 (“The District Court has broad discretion to stay 

proceedings as an incident to its power to control its own docket.”) (citing Landis, 299 U.S. at 254). 

District courts typically consider three factors when deciding whether to stay litigation pending 

IPR of the asserted patent(s): “(1) whether the stay will unduly prejudice the nonmoving party, (2) 

whether the proceedings before the court have reached an advanced stage, including whether discovery is 

complete and a trial date has been set, and (3) whether the stay will simplify issues in question in the 

litigation.” Trover Grp., Inc. v. Dedicated Micros USA, No. 2:13-CV-1047-WCB, 2015 WL 1069179, at 

*2 (E.D. Tex. Mar. 11, 2015) (collecting cases). 

III. ANALYSIS 

a. Stage of the Case Proceedings

Defendant argues that the case is still at an early stage and much of the work of this litigation is 

still ahead. (Mot. at 9-10.) Defendant notes fact discovery is not closed, claim construction is set for 

October 2024 and dispositive motions are not due until December 2024. (Id. at 10.) Defendant contends a 

stay at this stage would conserve both party and judicial resources. (Id.)

“Usually, the Court evaluates the stage of the case as of the time the motion was filed.” Peloton 

Interactive, 2019 WL 3826051, at *5 (quoting Papst Licensing GMBH & Co., KG v. Apple, Inc., 6:15-cv1095-RWS, slip op. at 7 (E.D. Tex. June 16, 2017)) (citing VirtualAgility, 759 F.3d at 1317). The Motion 

was filed and now decided quite early in the case with all IPRs instituted well in advance of trial, as such 

this factor weighs in favor of a stay.

b. Issue Simplification 

Whether a stay “will result in simplification of the issues before a court is viewed as the most 

important factor when evaluating a motion to stay.” Uniloc USA, 2017 WL 2899690, at *3 (citing 

Case 2:23-cv-00306-JRG-RSP Document 81 Filed 06/14/24 Page 2 of 5 PageID #: 4387

Intellectual Ventures II LLC v. Kemper Corp., No. 6:16-cv-81-JRG, 2016 WL 7634422, at *2 (E.D. Tex. 

Nov. 7, 2016); NFC Tech., 2015 WL 1069111, at *4). “Simplification of the issues depends on whether 

the PTAB decides to grant the petition.” Id. (citing Trover, 2015 WL 1069179, at *4; Loyalty Conversion 

Sys. Corp. v. Am. Airlines, Inc., No. 2:13-cv-655-WCB, 2014 WL 3736514, at *2 (E.D. Tex. July 29, 

2014)).

Defendant argues that because the PTAB has instituted IPR trials as to all Asserted Patents on 

multiple grounds it is very likely that there will be significant simplification by invalidating the asserted 

claims. (Mot. at 8.) Defendants cite recent statistics that instituted IPRs lead to invalidation of at least one 

claim in 85.5% of cases and all claims in 67.1% of cases. (Id.) Defendant contends from this, the most 

likely outcome is that all claims are found invalid and the case is dispensed with in its entirety. (Id.) 

Defendants contend that even if not all claims are invalidated, there will still be simplification based on 

IPR estoppel disposing of many invalidity arguments. (Id. at 8-9.)

Plaintiff contends there will be little simplification if even one claim survives the IPRs as the 

Accused Products are accused of infringing all claims. (Opp. at 10.) Plaintiff challenges Defendant’s 

allegation that the PTAB is likely to invalidate all claims. (Id. at 11.) Plaintiff contends that using 

Defendant’s statistics show that there is actually a 70% chance that a claim will survive. 1 (Id.) 

Additionally, Plaintiff notes that one institution decision included a rare dissent which Plaintiff argues 

shows a particular weakness of that IPR. (Id. at 11-12.) Last, Plaintiff contends there will be little 

simplification if not all claims are invalidated in the IPRs because Defendant has invalidity grounds that 

will not be impacted by the IPR estoppel. (Id. at 12-13.)

The Court finds this factor is fairly neutral. Defendant is correct that there is a possibility that all 

claims will be invalidated but Plaintiff is also correct there is a significant chance that some claims will 

1 Plaintiff contends this value is derived by multiplying .671 by .671 by .671 to reach a 30% chance that all claims of 

each of the three patents are invalidated. (Id.) The Court notes that this calculation is misleading as such a simplistic 

determination of the probability of multiple events only holds true when the probability of each event is independent 

of the other such as with a coin flip. Here, the Court finds it unlikely that the outcomes of these IPRs are statistically 

independent where their subject matter is similar and two of the patents are related.

remain.2 In that instance, there would be some simplification of this case through the application of IPR 

estoppel. However, this Court is accustomed to how such instances play out in practice and fully 

anticipates that Defendants will prepare significant alternative invalidity theories mitigating any 

simplification on account of IPR estoppel.

c. Undue Prejudice

Defendant contends Plaintiff will not be unduly prejudiced because Plaintiff itself has already 

delayed this case and the parties are not competitors such that the Court should withhold a stay. (Mot. at 

11-14.) For delay, Defendants note that this case was originally brought in the Southern District of 

California before being dismissed and refiled here, causing a delay of several months. (Id. at 11-12.) In 

light of Plaintiff’s delay, Defendant argues it cannot be credibly claimed any delay caused by a stay 

would prejudice Plaintiff. (Id.) Defendant further claims that the market and Plaintiff’s licensing history 

are such that it is not the case that the parties’ relationship should weigh against a stay. (Id. at 12-13.) 

Defendant contends there are a great many market participants, many of whom Defendant has licensed, 

and because Plaintiff does not face loss of market value curable in this case, there is no undue prejudice. 

(Id. at 13 (citing out-of-circuit cases).)

Plaintiff argues it was diligent in bringing this action, having attempted discussion directly with 

Defendant before filing in California and then learning more of Defendant’s corporate structure and 

ultimately refiling accordingly. (Opp. at 9.) Plaintiff also argues that Defendant is misleading as to the 

market players, and that the parties materially compete. (Opp. at 7-10.) Plaintiff contends Samsung makes 

up more than half of all Plaintiff’s sales, and in 2021 Plaintiff’s sales were nearly all of Samsung’s 

purchases in the relevant category. (Id. at 7-8.) However, Plaintiff contends now its sales only make up 

less than half of Samsung’s purchases, due directly to Defendant’s infringement. (Id. at 8.) Plaintiff 

further contends that Defendant’s claim of other market participants is misleading as the cited licenses are 

to competitors of Samsung, not itself. (Id. at 10.)

2 While the parties have presented statistics that they treat as giving exact chances, these are highly speculative and 

it would be improper to blindly apply them to any individual case.

The Court finds this factor weighs significantly against staying this case. The parties concede that 

they are competitors, Defendant’s argument on this point is only that their competition does not result in 

sufficient undue prejudice to weigh heavily on this factor. The Court does not find this argument availing. 

While Plaintiff has licensed its patents to other parties, Defendant has not shown that such a practice 

diminishes the impact on the competition between the parties. In contrast, Plaintiff has identified a 

specific instance of competition that has a significant impact on Plaintiff’s business which is, pending a 

finding of infringement, directly impacted by the protections provided by the asserted patents. In light of 

such facts, the Court finds that Plaintiff would be unduly prejudiced by a stay in this case. See Tesco 

Corp. v. Weatherford Int'l, Inc., 599 F. Supp. 2d 848, 851 (S.D. Tex. 2009) (“Where the parties are direct 

competitors, a stay would likely prejudice the non-movant.”).

While the Court might otherwise be inclined to grant a stay where Final Written Decisions on all 

asserted claims are expected very close to trial, the parties being direct competitors relevant to the 

accused products changes the balancing of factors. Here the Court finds on balance, Defendant has not 

carried its burden to show a stay is appropriate here. See Peloton Interactive, Inc. v. Flywheel Sports, Inc., 

No. 218-cv-390-RWS-RSP, 2019 WL 3826051, at *1 (E.D. Tex. Aug. 14, 2019)

IV. CONCLUSION

For the reasons stated, the Court DENIES Defendant’s motion to stay.
