Case No. 24-cv-04388-JSC
ORDER RE: DEFENDANT'S MOTION
TO STAY PENDING IPR
PROCEEDINGS
Re: Dkt. No. 58

12
13

Dialect alleges Google infringes seven of its patents: U.S. Patent Nos. 7,398,209 (‘209

14

patent),1 7,502,738 (‘738 patent), 7,640,160 (‘160 patent), 7,693,720 (‘720 patent), 8,015,006

15

(‘006 patent), 8,447,607 (‘607 patent), and 8,849,652 (‘652 patent) (collectively, the “asserted

16

patents). Google now moves to stay these proceedings pending inter partes review (“IPR”). (Dkt.

17

No. 58.)2 After carefully considering the parties’ pleadings and having had the benefit of oral

18

argument on September 26, 2024, the Court GRANTS Google’s motion to stay.
BACKGROUND

19
I.

20

Second Amended Complaint Allegations

21

The asserted patents were all invented by VoiceBox Technologies. “Voicebox was a key

22

pioneer in the fields of voice recognition technology and natural language understanding.” (Dkt.

23

No. 67 ¶ 1.) The technologies provide key functionality for a variety of electronic devices. (Id.)

24
25
26
27
28

The parties agreed at oral argument that the ‘209 patent was no longer at issue in the present case
because Dialect had amended its complaint to exclude it. Upon review of the Second Amended
Complaint, Dialect still maintains its ‘209 patent is part of this suit. (See, e.g. Dkt. No. 67 ¶¶ 1,
19-24, 33, 65, 78-115.) Indeed, Count One is for infringement of the ‘209 patent. Google has not
disclosed whether it sought IPR institution of ‘209.

Dialect is the current owner and assignee of the asserted patents. (Dkt. No. 67 ¶ 5.)
Dialect accuses Google of infringing its patents through several of its products and

2

8

services, including:
the Google Assistant Platform, including Google Assistant’s
Conversational Actions, App Actions, smart home Actions, Google
Assistant for Android Auto, and/or media Actions; servers, network
infrastructure, smartphones, tablets, and internet of things (“IoT”)
devices such as Google Home devices comprising software to access
such Google Assistant Platform products and services alone or in
combination with Android software, Android Auto software, and/or
Android Automotive OS software; and Dialogflow virtual agents
comprising Google Assistant Platform technology (collectively, the
‘Accused Google Assistant products and Services’).

(Dkt. No. 67 ¶ 76.) Dialect alleges each of these products and services infringes one or all the

asserted patents. (Dkt. No. 67 ¶¶ 76-77.)
II.

Procedural History
On April 3, 2023, Dialect filed a complaint in the District of Delaware against Google for

13

alleged patent infringement. (Dkt. No. 1.) Google moved to dismiss the case on June 9, 2023, and

14

Dialect subsequently filed its First Amended Complaint on June 23, 2023. (Dkt. Nos. 9, 14.) In

15

light of the amended complaint, the Delaware court denied Google’s motion as moot on July 3,

16

2023, and Google filed a new motion to dismiss on July 7, 2023. (Dkt. Nos. 15, 16). On August

17

23, 2023, before the Delaware court heard the motion to dismiss, Google filed a motion to transfer

18

the case to the Northern District of California, which the Delaware court granted on March 28,

19

2024. (Dkt. Nos. 22, 32.) The case was transferred to this court on July 23, 2024. (Dkt. No. 33.)

20

Upon reassignment, this Court denied the still-pending motion to dismiss as moot and directed

21

Google to refile its motion in accordance with the local rules of the district. (Dkt. No. 54.)

22

Google then filed the present motion to stay pending IPR on August 12, 2024, and renewed its

23

motion to dismiss on August 19, 2024. (Dkt. Nos. 58, 61.) On September 4, 2024, the parties

24

stipulated to Dialect’s filing of its Second Amended Complaint and agreed to extend Google’s

25

time to respond to that complaint until after this Court rules on the pending motion to stay. (Dkt.

26

Nos. 66, 67.)

27
28

On April 5, 2024, Google filed IPR petitions “challenging all patents asserted in the
Amended Complaint,” though these petitions do not encompass all the claims across the asserted
2

1

patents. 3 (Dkt. No. 58 at 39.) The Patent Trial and Appeal Board (“PTAB”) is expected to make

2

institution decisions for the ‘738, ‘160, ‘006, ‘607, and ‘652 patents by October 16, 2024, and for

3

the ‘720 patent by October 25, 2024. (Dkt. No. 58 at 9.)

DISCUSSION
I.

5

“[T]he power to stay proceedings is incidental to the power inherent in every court to

6

United States District Court
Northern District of California

Motion to Stay

7

control the disposition of the causes on its docket with economy of time and effort for itself, for

8

counsel, and for litigants.” Landis v. N. Am. Co., 299 U.S. 248, 254 (1936). In particular, a

9

“district court has inherent power to stay proceedings pending resolution of parallel actions in

10

other courts.” Dietz v. Bouldin, 579 U.S. 40, 47 (2016) (citing Landis, 299 U.S. at 254). This

11

inherent power extends to staying proceedings pending resolution of inter partes review. See

12

Topia Tech., Inc. v. Dropbox Inc., No. 2023-cv-00062-JSC, 2024 WL 3437823 at *3 (N.D. Cal.

13

May 12, 2023). “The proponent of a stay bears the burden of establishing its need.” Clinton v.

14

Jones, 520 U.S. 681, 708 (1997).

15

In deciding whether to stay a case, courts must “weigh [the] competing interests” of

16

“economy of time and effort for itself, for counsel, and for litigants” and “maintain an even

17

balance.” Landis, 299 U.S. at 254-55. Courts consider the following in guiding this balancing

18

exercise:
(1) the stage of the litigation, including whether discovery is or will
be almost completed and whether the matter has been marked for
trial;
(2) whether a stay will unduly prejudice or tactically disadvantage the
nonmoving party; and
(3) whether a stay will simplify the issues in question and streamline
the trial, thereby reducing the burden of litigation on the parties
and on the court.

25
26
27
28

Google also filed an IPR petition for the U.S. Patent No. 9,031,845 (‘845 patent), and this patent
is referenced in the motion to stay pleadings. (Dkt. Nos. 58, 58-8.) Dialect’s Second Amended
Complaint removes all allegations related to the ‘845 patent.

A. Stage of Litigation

1

United States District Court
Northern District of California

2

“The first factor the Court considers is whether the litigation is at an early stage.” Zomm,

3

LLC v. Apple Inc., 391 F. Supp. 3d 946, 956 (N.D. Cal. 2019) (citing AT&T Intellectual Property I

4

v. Tivo, Inc., 774 F. Supp. 2d 1049, 1052 (N.D. Cal. 2011)). “An early stay may save the parties

5

and the Court from unnecessarily expending significant resources. A stay later in the proceedings

6

will likely produce less benefit and increase the possibility of prejudice.” Largan Precision Co. v.

7

Motorola Mobility LLC, No. 21-cv-09138-JSW, 2022 WL 294935, at *4 (N.D. Cal. July 26,

8

2022). Courts typically consider “(1) whether parties have engaged in costly expert discovery and

9

dispositive motion practice; (2) whether the court has issued its claim construction order; and (3)

10

whether the court has set a trial date.” Id.; see also PersonalWeb Techs., LLC v. Apple Ins., 69 F.

11

Supp. 3d 1022, 1025-26 (N.D. Cal. 2014) (collecting cases).

12

The early stage of litigation favors a stay. This case was filed in April of 2023, but no

13

court has considered the merits of Google’s motions to dismiss, and Dialect has amended its

14

complaint after each such motion was filed, including as recently as August of this year. “The

15

parties agree that this case is in its infancy.” (Dkt. 63 at 13.) The parties have not engaged in any

16

discovery, there has not yet been an initial case management hearing, the Court has not set a trial

17

date for the case, and the parties have not yet fully briefed the most recently filed motion to

18

dismiss. See Speir Techs. Ltd. v. Apple, Inc., No. 23-cv-00095-EJD, 2023 WL 2714931, at *2

19

(N.D. Cal. Mar. 30, 2023) (finding incomplete discovery, no set trial date, no case management

20

schedule, and no answer by the defendant to the amended complaint as factors weighing in favor

21

of a stay).

22

Dialect’s argument that a stay is premature since the Board will make its institution

23

decision in the next month is unpersuasive. “Either party may file a motion to lift the stay if any

24

part of the petitions for IPR are denied—so any concern that the motion is premature is alleviated

25

by the short time frame of the initial stay and the Court’s willingness to reevaluate the stay if inter

26

partes review is not instituted for all of the asserted claims.” Anza Tech., Inc. v. Toshiba Am. Elec.

27

Components Inc., No. 17-cv-0707289-LHK, 2018 WL 4859167 at *2 (cleaned up) (quoting

The early stage of litigation favors a stay.
a. Simplification of the Issues
“[T]he filing of an IPR request does not by itself simplify the issues in a case.” DiCon

5

Fiberoptics, Inc. v. Precisely Microtechnology Corp., No. 15-cv-1362-BLF, 2015 WL 12859346,

6

at *2 (N.D. Cal. Oct. 13, 2015). A stay is appropriate when a Patent and Trademark Office

7

(“PTO”) proceeding “would be likely to assist the court in determining patent validity and, if the

8

claims were canceled in the reexamination, would eliminate the need to try the infringement

9

issue.” Slip Track Sys., Inc. v. Metal Lite, Inc., 159 F.3d 1337, 1341 (Fed. Cir. 1998). When the

10

IPR petitions encompass all the asserted patents in a case, courts have found “[i]f granted, an IPR

11

will, likely, simplify [the] case.” Int’l Test Sols., Inc. v. Mipox Int’l Corporation, No. 16-cv-

12

00791-RS, 2017 WL 1316549, at *2 (N.D. Cal. Apr. 10, 2017).

13

“The standard is simplification of the district court case, not complete elimination of it by

14

the PTAB.” Finjan v. Symantec Corp., 139 F. Supp. 3d 1032, 1036 (N.D. Cal. 2015) (citing

15

LELO, Inc. v. Standard Innovation (US) Corp., No. 13-cv-01393-JD, 2014 WL 2879851, at *3

16

(N.D. Cal. June 24, 2014)). Thus, “[e]ven when claims survive an IPR proceeding, the proceeding

17

can facilitate trial by providing the Court with expert opinion of the PTO and clarifying the scope

18

of the claims.” Topia Tech., 2024 WL 3437823, at *4 (quoting Largan Precision Co., v. Motorola

19

Mobility LLC., No. 21-cv-09138-JSW, 2022 WL 2954935, at *2 (N.D. Cal. 26, 2022)). And when

20

claims do not survive IPR, “estoppel narrows invalidity arguments petitioners can bring in

21

subsequent proceedings.” Id. (citing 35 U.S.C.A. § 315(e)(2)).

22

Google’s IPR petitions encompass almost all the asserted patents and most claims across

23

the same. (Dkt. 58 at 9 (the IPR petitions encompass 151 out of the 213 total claims in the

24

patents).) Given the sheer number of claims Plaintiff asserts, elimination of even some of the

25

claims will simplify this action. Dialect does not dispute the potential for simplification, but

26

instead argues any simplification is speculative because Google does not explain why there is a

27

high likelihood the claims will be instituted. (Dkt. 63 at 13.) Dialect also argues the PTAB’s

28

institution decisions on Amazon’s recent challenge of eight similar but unrelated patents
5

1

demonstrates there is minimal likelihood of institution for the asserted patents. (Dkt. 63 at 7-8,

2

11.)

United States District Court
Northern District of California

3

Despite Dialect’s proffered evidence, the PTAB is likely to institute some or all of

4

Google’s IPR petitions. The PTAB reported it instituted 67% of all petitions in the fiscal year

5

2023, which was comparable to 66% of petitions instituted in the fiscal year 2022 and a near 10%

6

increase in the previous two years’ institution rates (56% and 58% institution rates in 2020 and

7

2021 respectively). See U.S. PAT. & TRADEMARK OFF., PTAB Trial Statistics FY24 Q3

8

Outcome Roundup IPR, PGR, at 6, https://www.uspto.gov/sites/default/files/documents/ptab_aia_

9

fy2024 _q3_roundup_.pdf. And the current year so far shares a similarly high institution rate. Id.

10

(66% institution rate for the year 2024 through June 30, 2024). Indeed, Dialect’s evidence that

11

two out of eight patents with the same inventors and similar subject matter were instituted

12

suggests that at least some of the asserted petitions are likely to be instituted. (Dkt. No. 63 at 7-8.)

13

For example, the claim for the asserted patent ‘607 bears some resemblance to the claim

14

description of the instituted patent ‘681. (Compare Dkt. 67 ¶ 56 (“A device for processing natural

15

language inputs, comprising one or more processors configured to: receive a natural language

16

utterance from a user; … generate a speech-based transcription based on a personal cognitive

17

model associated with the user and a general cognitive model, wherein the personal cognitive

18

model includes information on one or more prior interactions between the device and the user.”);

19

with Dkt. No. 63-3 at 18-19 (“The ‘681 patent, … generally describes a human to machine voice

20

user interface that uses short-term and long-term knowledge to understand and respond to

21

utterances in an identified context. Short-term knowledge may accumulate during a single

22

conversation, e.g., as a history of the conversation. Long-term knowledge is unconstrained by a

23

current session, is user-centric, and accumulates over time to build user profiles.”) (cleaned-up).)

24

So, there is a substantial likelihood some or all the asserted patents will be instituted. This

25

will likely simplify the issues in the present case and will benefit the Court in “determining patent

26

validity and, if the claims were canceled in the reexamination, would eliminate the need to try the

27

infringement issue.” Slip Track Sys, 159 F.3d at 1341. This factor weighs in favor of a stay.

28
6

1
2

“Third, the Court looks to whether a stay would unduly prejudice or present a clear tactical

3

disadvantage to the nonmoving party.” PersonalWeb Techs., 69 F. Supp. 3d at 1029. And

4

“[c]ourts have repeatedly found no undue prejudice unless the patentee makes a specific showing

5

of prejudice beyond the delay necessarily inherent in any stay.” Palo Alto Networks, inc. v. Packet

6

Intelligence LLC, No. 19-cv-02471-WHO, 2020 WL 5760475, at *2 (N.D. Cal. Sept. 28, 2020).

7

Dialect argues (1) Google “has not acted expeditiously;” (2) “Google has repeatedly and

8

systematically attempted to delay” this case; and (3) “there is no risk of wasted resources” were

9

this Court to wait for institution decisions prior to staying the case. (Dkt. No. 63 at 14-15.) None

10
11

United States District Court
Northern District of California

b. Prejudice to Dialect

of these arguments is persuasive here.
First, while Dialect is correct Google did not file its petitions until “a mere day before the

12

statutory bar,” (Dkt. No. 63 at 14), courts have previously found “the timing of these filings,

13

standing alone,” is “insufficient evidence of undue prejudice.” Bell Semiconductor, LLC v. NXP

14

USA, Inc., No. 22-cv-02133-HDV-ADS, 2024 WL 3914500, at *2. And other courts have

15

similarly found that when a defendant files IPR petitions within the statutory period, such action is

16

neutral at best. Cortex MCP, Inc. v. Visa, Inc., No. 23-cv-05720-EJD, 2024 WL 3511637, at *3

17

(N.D. Cal. July 22, 2024). Further, Dialect does not explain how this alleged delay prejudices it,

18

especially in light of its amended complaints, the most recent of which also removed one of its

19

asserted patents. (See Dkt. No. 64-2 at 3.)

20

Second, Dialect’s argument that Google has attempted to delay these proceedings is

21

unpersuasive. Google filed numerous motions to dismiss within the required deadline for each of

22

Dialect’s complaints. Google also moved to transfer the case soon after Dialect filed its First

23

Amended Complaint. Id. Further, Dialect did not file its Second Amended Complaint until

24

September 4, 2024. Google has not dragged its feet in this proceeding.

25

Third, Dialect contends there is minimal risk of expending resources when an institution

26

decision is expected soon after this Court grants a stay in this case. And most cases Google cites

27

to counter this position involve longer periods of time between the order to stay proceedings and

28

the institution decision than the present case. See, e.g., RJ Tech. LLC v. Apple Inc., No. 22-cv7

1

01874-JVS (JDEx), 2023 WL 8188475 (four months); Topia Tech., 2023 WL 3437823 (four

2

months); Viavi Sols. Inc. v. Platinum Optics Tech. Inc., No. 20-cv-05501-EJD, 2021 WL 1893142

3

(N.D. Cal. May 11, 2021) (five months); Evolutionary Intel., LLC v. Facebook, Inc., No. 13-cv-

4

04202-SI, 2014 WL 261837 (four months). On the other hand, courts have previously found a

5

stay as short as a month to be reasonable. Cortex, 2024 WL 3511637, at *3 (“The Court finds that

6

this timing does not prejudice [the defendant.]”). And, here, Google’s motion to dismiss the

7

Second Amended Complaint is pending. If the Court does not grant a stay now, the parties’ and

8

the Court’s resources may be wasted working on that motion before the IPR institution decisions.

9

Thus, although the stay period may be short, the parties and the Court will still conserve valuable

10

United States District Court
Northern District of California

11

resources during this time.
“Absent a showing that the parties are direct competitors and that the plaintiff’s

12

competitive position would be prejudiced by a stay, courts generally find that a plaintiff does not

13

risk irreparable harm” from the grant of a stay. Finjan, 139 F. Supp. 3d at 1038 (cleaned up).

14

Dialect is not a competitor to Google. While Dialect argues this factor alone “does not negate[] a

15

finding of undue prejudice,” it does not explain why this factor would weigh in its favor. (Dkt.

16

No. 63 at 15.) Further, absent competition between the parties, courts have rarely found undue

17

prejudice exists. See RJ Tech., 2023 WL 8188475 at *4 (collecting cases).

18

And Dialect does not appear to argue it would truly suffer any prejudice from a stay,

19

arguing instead that “[a] showing of undue prejudice is not necessary to defeat a motion for a pre-

20

institution stay.” (Dkt. 63 at 15.) Even so, Dialect has not shown how a stay would prejudice it in

21

any meaningful way. This factor weighs in favor of a stay.

22

CONCLUSION

23

Because a stay will benefit the Court and help conserve the Court’s and the parties’

24

resources at this early stage while not prejudicing Dialect, the Court GRANTS Google’s motion to

25

stay until further Court order. The Court will hold a status conference on December 12, 2024 at

26

1:30 p.m. via Zoom video to address the stay.

27
28

If the parties agree the stay should continue in light of the expected October 2024 IPR
institution decisions, they shall so stipulate in advance of the December 5 conference.
8

1
2
3

If the parties agree the stay should be dissolved in light of the October 2024 IPR decisions,
they shall submit a joint case management statement by December 5, 2024.
If Dialect believes a stay is no longer warranted in light of the IPR institution decisions

4

(and Google disagrees), Dialect shall file a written submission, not to exceed 10 pages, by

5

November 21, 2024, explaining why a continued stay is not warranted. Google may respond by

6

November 27, 2024, via written submission not to exceed 10 pages. The Court will then address

7

the stay at the December 12, 2024 status conference.

8

This Order disposes of Docket No. 58.

9

IT IS SO ORDERED.
