Case No. 1:19-cv-1482-JLT-SKO

v.
E. & J. GALLO WINERY,

(Doc. 55)
15

Defendant.

16
17

The matter before the Court is grounded in patent law and concerns the doctrine of

18

inequitable conduct. Following the filing of Vineyard Investigations’ patent infringement

19

complaint against E. & J. Gallo Winery, Defendant Gallo filed its Answer and asserted seven

20

counterclaims. Plaintiff filed a motion to dismiss Defendant’s inequitable conduct counterclaim

21

pursuant Federal Civil Procedure Rules 12(b)(6) and 9(b). For reasons discussed below, the

22

Court DENIES Plaintiff’s motion to dismiss.

23
24

I.

BACKGROUND

On October 1, 2019, Vineyard Investigations filed a patent infringement complaint against

25

E. & J. Gallo Winery (Doc. 1) and amended the complaint on October 22, 2021 (Doc. 52).

26

Plaintiff’s first amended complaint alleged Defendant infringed three patents, United States

27

Patent Nos.: 8,528,834 (‘834 Patent); 6,947,810 (‘810 Patent); and 10,645,881 (‘881 Patent).

28

(Doc. 52 at 2.) The three patents-in-suit “relate to automated irrigation and dispensing of
1

1

chemicals to crops using data and rules received from sensors and other sources of information”

2

and “claim priority to the same application, Application No. 09/872,477 (the ‘477 Application)”

3

which named Dr. Paul Skinner as the inventor. (Doc. 61 at 8.) The ‘477 Application was filed in

4

2001 by patent attorney Charles Kulas. (Id.)
Defendant timely filed its Answer (Doc. 54) and asserted “seven counterclaims for

5
6

declaratory judgment of noninfringement and invalidity” of Patent ‘834, Patent ‘810, and Patent

7

‘881 (“Asserted Patents”), and “a counterclaim of inequitable conduct as to the Asserted Patents.”

8

(Doc. 61 at 11.) Defendant’s inequitable conduct counterclaim alleged that Plaintiff owed a duty

9

of disclosure to the PTO when prosecuting the Asserted Patents, and Plaintiff breached its duty

10

when it failed to disclose and/or concealed the Williams Paper1 and IPM Website2 information

11

despite the information being material to patentability. (See generally Docs. 54, 61.) Defendant

12

alleged Plaintiff’s nondisclosure of the material information constitute inequitable conduct. (Id.)

13

In response, Plaintiff filed a motion to dismiss seeking the dismissal of Defendant’s

14

inequitable conduct counterclaim. (Doc. 55.) On December 12, 2021, parties filed a “Stipulation

15

to Extend Briefing Schedule on Plaintiff Vineyard Investigations’ Motion to Dismiss Equitable

16

Conduct Counterclaims” (Doc. 57), and the Court granted the stipulation (Doc. 59). In

17

accordance with the stipulated briefing schedule, Defendant timely filed its Opposition on

18

January 18, 2022, and Plaintiff filed its Reply on January 25, 2022. (Docs. 61, 63.) Pending

19

before the Court is Plaintiff’s motion to dismiss Defendant's inequitable conduct counterclaim

20

pursuant Federal Civil Procedure Rule 12(b) and Rule 9(b). (Doc. 55)

21

STANDARD OF DECISION

A motion to dismiss under Federal Civil Procedure Rule 12(b)(6) is a challenge to the
legal sufficiency of the allegations set forth in the complaint. Navarro v. Block, 250 F.3d 729,

24
“The Williams Paper is an article published in the 1998-1999 volume of the Viticulture Research Report, a
periodical published by the California Table Grape Commission in Fresno, CA. (Countercl. ¶76.) The Williams
Paper describes an irrigation trial conducted to determine the effects of various irrigation amounts on vine
productivity of a species of table grapes.” (Doc. 61 at 8.)

“The IPM Website was a publicly available internet site maintained by the University of California’s Integrated
Pest Management Project. As of 2000, the home page of the site contained numerous links to pages of information
that in turn linked to other pages, requiring considerable navigation by a visitor to find relevant information.” (Doc.
61 at 8.)
2

2

1

732 (9th Cir. 2001). Dismissal is proper where there is either a “lack of a cognizable legal

2

theory” or “the absence of sufficient facts alleged under a cognizable legal theory.” Balistreri v.

3

Pacifica Police Dept., 901 F.2d 696, 699 (9th Cir. 1990). In ruling on a motion to dismiss for

4

failure to state a claim, “the court generally accepts as true the allegations in the complaint,

5

construes the pleading in the light most favorable to the party opposing the motion, and resolves

6

all doubts in the pleader’s favor.” Beco Dairy Automation, Inc. v. Glob. Tech Sys., Inc., 104 F.

7

Supp. 3d 1023, 1030 (E.D. Cal. 2015) (citing Lazy Y. Ranch Ltd. v. Behrens, 546 F.3d 580, 588

8

(9th Cir. 2008)).
To survive a 12(b)(6) motion to dismiss, the complaint must allege “enough facts to state

9
10

a claim to relief that is plausible on its face.” Bell Atl. Corp. v. Twombly, 550 U.S. 544, 570

11

(2007). “A claim has facial plausibility when the plaintiff pleads factual content that allows the

12

court to draw the reasonable inference that the defendant is liable for the misconduct alleged.”

13

Ashcroft v. Iqbal, 556 U.S. 662, 678 (2009). “The plausibility standard is not akin to a

14

probability requirement, but it asks for more than a sheer possibility that a defendant has acted

15

unlawfully.” Id. (quoting Twombly, 550 U.S. at 556) (internal quotations omitted)); see also

16

Beco, 104 F. Supp. 3d at 1031. “Where a complaint pleads facts that are ‘merely consistent with’

17

a defendant’s liability, it ‘stops short of the line between possibility and plausibility for

18

entitlement to relief.’” Id. (quoting Twombly, 550 U.S. at 557).
Further, though a complaint subject to Rule 12(b)(6) dismissal “does not need detailed

19
20

factual allegations[;]” the pleading party must provide the “grounds of his entitlement to relief”

21

beyond mere “labels and conclusions” and “formulaic recitation of the elements.” See Twombly,

22

550 U.S. at 555. The “[c]omplaint must describe the alleged misconduct in enough detail to lay

23

the foundation for [the] identified legal claim.” Beco, 104 F. Supp. 3d at 1031. In other words,

24

the complaint must contain “well-pleaded facts” from which the Court can “infer more than the

25

mere possibility of misconduct.” Pensmore Reinforcement Techs., LLC v. Cornerstone Mfg. &

26

Distribution, Inc., 609 F. Supp. 3d 1092, 1099 (C.D. Cal. 2022) (quoting Iqbal, 556 U.S. 662 at

27

679)).

III.

LEGAL STANDARD

A. Duty of Candor and Good Faith
Each inventor named in a patent application has “a duty of candor and good faith in

4

dealing with the Office, which includes a duty to disclose to the Office all information known to

5

that individual to be material to patentability.” 37 C.F.R. § 1.56(a). The duty of candor and good

6

faith also extends to a patent applicant’s counsel. Molins PLC v. Textron, Inc., 48 F.3d 1172,

7

1178 (Fed. Cir. 1995). “The duty to disclose information exists with respect to each pending

8

claim.” 37 C.F.R. § 1.56(a). “A breach of this duty [of candor and good faith] constitutes

9

inequitable conduct.” Molins, 48 F.3d at 1178; see also Hangzhou Chic Intelligent Tech. Co.,

10

Ltd. Razor USA LLC, No. 216-CV-06359-RGK (AJWX), 2016 WL 10518582, at *3 (C.D. Cal.

11

2016)). “[N]o patent will be granted on an application in connection with which fraud on the

12

Office was practiced or attempted or the duty of disclosure was violated through bad faith or

13

intentional misconduct.” 37 C.F.R. § 1.56

14

B. Inequitable Conduct

15

“Inequitable conduct is an equitable defense to patent infringement that, if proved, bars

16

enforcement of a patent.” Therasense, Inc. v. Becton, Dickinson & Co., 649 F.3d 1276, 1285

17

(Fed. Cir. 2011). To succeed on an inequitable conduct claim at trial, the pleading party must

18

prove that: “(1) an individual associated with the filing and prosecution of a patent application

19

affirmatively misrepresents a material fact, fails to disclose material information, or submits false

20

material information; and (2) the individual does so with the specific intent to deceive the

21

[USPTO].” Capella Photonics, Inc. v. Cisco Sys., Inc., 77 F. Supp. 3d 850 (N.D. Cal. 2014)

22

(citing Exergen Corp. v. Wal–Mart Stores, Inc., 575 F.3d 1312, 1327 n.3 (Fed. Cir. 2009)). A

23

patent applicant is found to have withheld information with the requisite intent to deceive if they

24

“knew of the reference, knew that it was material, and made a deliberate decision to withhold it.”

25

Therasense, 649 F.3d at 1290.

26

C. Federal Civil Procedure Rule 9(b)

27

1. Particularity Requirement

28

Federal Civil Procedure Rule 9(b) requires that “[i]n all averments of fraud or mistake, the
4

1

circumstances constituting fraud or mistake shall be stated with particularity.” Rule 9(b) also

2

governs the pleading standard of inequitable conduct claims, “a broader concept of fraud,” and

3

requires a claimant to allege with particularity “the specific who, what, when, where, and how of

4

the material misrepresentation or omission committed before the PTO.” Exergen, 575 F.3d at

5

1327 (citing Ferguson Beauregard/Logic Controls, Div. of Dover Res., Inc. v. Mega systems,

6

LLC, 350 F.3d 1327, 1344 (Fed. Cir. 2003)). The pleading must also “identify the particular

7

claim limitations, or combination of claim limitations, that are supposedly absent from the

8

information of record.” Exergen, 575 F.3d at 1328-29. “A pleading that simply avers the

9

substantive elements of inequitable conduct, without setting forth the particularized factual bases

10

for the allegation, does not satisfy Rule 9(b).” Pensmore, 609 F. Supp. 3d at 1099.

11

2. State of Mind Requirement

12

Rule 9(b) also states that “[m]alice, intent, knowledge, and other conditions of mind of a

13

person may be averred generally.” Exergen, 575 F.3d at 1327. “The relevant ‘conditions of

14

mind’ for inequitable conduct include: (1) knowledge of the withheld material information or of

15

the falsity of the material misrepresentation, and (2) specific intent to deceive the PTO.” Id.

16

Though “knowledge” and “intent” “may be averred generally[,]” a pleading of inequitable

17

conduct under Rule 9(b) must “include sufficient allegations of the underlying facts from which a

18

court may reasonably infer [that a specific individual] acted with the requisite state of mind.” Id.

19

at 1328.

20

A pleading of inequitable conduct will only survive a motion to dismiss if the claimant

21

satisfies both the particularity and state of mind requirements. Accordingly, a “well-pleaded

22

claim for inequitable conduct must allege facts supporting that (1) an individual associated with

23

the filing and prosecution of a patent application made an affirmative misrepresentation of a

24

material fact, failed to disclose material information, or submitted false information; and (2) the

25

individual did so with a specific intent to deceive the PTO.” Pensmore, 609 F. Supp. 3d at 1099

26

(internal quotations omitted) (internal citations omitted)).

27
28

IV.

DISCUSSION

Plaintiff argues for the dismissal of Defendant’s inequitable conduct counterclaim
5

1

asserting Defendant failed to meet Rule 9(b)’s pleading standard which requires Defendant to

2

plead the substantive elements of inequitable conduct with particularized facts. (Doc. 55 at 5.)

3

Specifically, Plaintiff argues Defendant failed to plead the “intent element . . . with sufficient

4

allegations of underlying facts from which a court may reasonably infer that a specific individual

5

withheld or misrepresented information with a specific intent to deceive the PTO.” (Id. at 6)

6

(internal citations omitted).) Plaintiff asserts that by providing in-text citations to the Williams

7

Paper and IPM Website “in the text of the patent [application itself], there can be no reasonable

8

inference that [Plaintiff] intended to hide the references from consideration by the Examiner.3”

9

(Id.)

10

In Opposition, Defendant urges the Court to deny Plaintiff’s motion arguing the

11

inequitable conduct counterclaim satisfied Rule 9(b) pleading requirements. (Doc. 61.)

12

Defendant reiterated the particularized facts previously alleged in its Answer (Doc. 54) and

13

asserts the inequitable conduct counterclaim:

14

sets forth in detail a course of conduct in which the sole named
inventor, Dr. Paul Skinner, and his patent attorney, deliberately and
selectively concealed information contained in two pieces of prior
art: the Williams Paper and the IPM Website, in order to persuade
[the PTO] to issue at least two of the patents-in-suit.

15
16
17

(Doc. 61 at 5) (internal citations omitted).) Defendant argues the “concealed information” was

18

material because:
they would have revealed elements of [Plaintiff’s] patent claims
that [Plaintiff] represented as purportedly new and inventive,
including at least: (1) use of emitters and sensors located in fixed
proximity to plants and (2) a central controller that used external
data, such as data retrieved from the Internet, to control the
dispensing of materials from such fixed emitters.

19
20
21
22
23

(Id.)4

24
25
26
27
28

3

Parties do not appear to dispute that Plaintiff included an in-text citation to the Williams Paper and IPM Website
within the patent specification. Plaintiff provided the following citation for the Williams Papers: “Irrigation of
Thompson Seedless Table Grape: Utilization of Crop Coefficients Developed at the Kearney Center for Use at the
Other Locations in the San Joaquin Valley” by Larry E. Williams, Don Luvisi, and Michael Costello, and the
following URL for the IPM Website: http://www.ipm.ucdavis.edu. (Doc. 55 at 4) (see also Doc. 61 at n.2-3).)
In addition, Defendant argues Plaintiff’s blatant disregard for the Court’s meet and confer requirement also supports
the Court denying Plaintiff’s motion. (Doc. 61 at 17.) The Court finds it unnecessary to adjudicate this independent
4

6

1
2

A. Defendant’s inequitable conduct counterclaim satisfies Rule 9(b) pleading standard.
Plaintiff’s motion to dismiss only addressed the pleading sufficiency of the inequitable

3

conduct element of specific intent to deceive. (See generally Doc. 55.) Though Plaintiff does not

4

directly dispute the sufficiency of Defendant’s pleading regarding the particularity requisite, the

5

Court will briefly address the Rule 9(b) analysis.

6

1. Particularity Requirement

7

To satisfy the particularity requirements of Rule 9(b), the pleading must identify “the

8

specific who, what, when, where, and how of the material misrepresentation . . . or omission” to

9

the PTO. Exergen, 575 F.3d at 1329. An allegation of inequitable conduct must identify:

10

•

the “who”: “name the specific individual associated with the filing or prosecution of

11

the application issuing” the patent, “who both knew of the material information and

12

deliberately withheld or misrepresented[;]” Beco, 104 F. Supp. 3d at 1034 (quoting

13

Exergen, 575 F.3d at 1329));

14

•

the “what” and “where”: “which claims, and which limitations in those claims, the

15

withheld references are relevant to, and where in those references the material

16

information is found[;]” Exergen, 575 F.3d at 1329;

17

•

the “how”: “state generally that the withheld claims are material and not cumulative

18

to the information already of record.” Id. In other words, “explain how the alleged

19

misrepresentation or omission is material to patentability.” Beco, 104 F. Supp. 3d at

20

1034.

21

Regarding a withholding claim, the claimant must also identify “the why”: explain “why’ the

22

withheld information is material and not cumulative, and ‘how’ an examiner would have used this

23

information in assessing the patentability of the claims.” Id.

24

Defendant identified the who, inventor Dr. Paul Skinner and patent attorney; the what,

25

when, and where: Patent ‘834, Patent ‘810, and Patent ‘881 which claim priority to the ‘477

26

Application filed in 2001 and the nondisclosure of the Williams Paper and IPM Website

27
28

ground for dismissal because the motion will be denied on its merits. The parties are admonished to carefully review
the operative standing order before undertaking further motions practice.

7

1

information regarding the irrigation experiments and phenology models. The “how” allegations

2

merit some additional discussion given the particularity requirement.

3

a.

4

Rule 9(b): Pleading Materiality

It is unclear if Plaintiff disputes the materiality of the IPM Website and Williams Paper.

5

Regarding materiality, Plaintiff stated only that “[t]here is much that can be said in rebuttal to

6

[Defendant’s] discussion about alleged ‘but-for’ materiality of the IPM website and Williams

7

[P]aper” but did not provide a legal argument. (Doc. 55 at 8.) Though Plaintiff’s motion lacks a

8

materiality argument, the Court deems it necessary to briefly address the matter as it is essential

9

to the Rule 9(b) analysis.
In addition to the “who, what, when, where, and how” particularity requirement, Rule 9(b)

10
11

also requires a claimant to identify “the particular claim limitations, or combination of claim

12

limitations, that are supposedly absent from the information of record.” Exergen, 575 F.3d at

13

1329. Such allegations “are necessary to explain both ‘why’ the withheld information is material

14

and not cumulative and ‘how’ an examiner would have used this information in assessing the

15

patentability of the claims.” Id. at 1329-30.
“[I]nformation is material to patentability when it is not cumulative to information . . . of

16
17

record in the application, and [it] establishes, by itself or in combination with other information, a

18

prima facie case of unpatentability of a claim; or [i]t refutes, or is inconsistent with, a position the

19

applicant takes in asserting an argument of patentability.” 37 C.F.R. § 1.56(b)(1) - (b)(2)(ii).

20

Stated differently, [i]nformation is material if a reasonable examiner would have considered it

21

important to the patentability of a claim.” Exergen, 575 F.3d at 1329 (emphasis added) (quoting

22

Regents of Univ. of Cal. v. Eli Lilly & Co., 119 F.3d 1559, 1570 (Fed. Cir. 1997)). “[T]he

23

materiality must reach the level of but-for materiality, meaning that ‘the PTO would not have

24

allowed a claim had it been aware of the undisclosed prior art.’” Therasense, 649 F.3d at 1291-

25

92.

26

In pleading its inequitable conduct claim (Doc. 54), Defendant generally alleged that the

27

Examiner would have rejected the claims and not have issued the Asserted Patents had Plaintiff

28

disclosed the prior material art (id. at 38). More specifically, Defendant asserted that at the time
8

1

of prosecuting the Asserted Patents, the IPM Website “provided information . . . material to the

2

patentability of at least claims 1, 8, 9, 11, 12, 14, and 15 of the ‘834 Patent . . . claims 1-36 of the

3

‘810 Patent and claims 1-48 of the ‘881 Patent.” (Id. at 32.) Defendant also asserted that the

4

Williams Paper disclosed claim limitations material to the patentability of the Asserted Patents:

5

“claims 1-15 of the ‘834 Patent,” regarding irrigation experiments.5 (Id. at 39.) Defendant

6

alleged Plaintiff withheld the IPM Website and Williams Paper information from the PTO despite

7

its materiality. In alleging materiality, Defendant argued the IPM Website and Williams Paper

8

information is material because it disclosed claim limitations that “anticipates and/or renders” the

9

Asserted Patents obvious. (Id. at 40.) Thus, “the claims identified would not have been allowed”

10

and the patents would not have been issued.6 (Id.)

11

Defendant further clarified the Williams Paper and IPM Website’s materiality alleging:

12

During the prosecution of the ‘810 Patent, Plaintiff “amended the pending claims to recite sensors

13

and emitters in ‘fixed proximity to and ‘associated with’ one or more plants” and represented to

14

the examiner “that these limitations are ‘not disclosed by nor made obvious in view of the prior

15

art.’” (Doc. 61 54 at 4010.) As a result, “[t]he Examiner allowed the claims to issue because,

16

based on the prior art before him, none of the references disclosed sensors and emitters in fixed

17

proximity to a plant.” (Id.) However, “[h]ad [Plaintiff] provided the Williams Paper to the

18

Examiner, the claims of the ‘810 Patent at least would have been found anticipated by or rendered

19

obvious by the Williams Paper, and would not have issued.” (Id. at 40-41.) Similarly, during the

20

prosecution of ‘834 Patent, Plaintiff amended the pending claims to recite “wherein the central

21

controller is responsive to a rule for controlling material dispensing, wherein the rule is retrieved

22

from a location on the Internet” and “remarked that this limitation is ‘not disclosed by or made

23

obvious in view of the prior art.’” (Doc. 54 at 35) (“The prior art completely fails to disclose

24
25
26
27
28

For example, the Williams Paper discloses “irrigation trials” in which “emitters were used to regulate “water
amounts in the various irrigation treatments, sensors placed in rows of grapevines, sensors in fixed proximity to the
plants, and external data.” (Doc. 54 at 40) (internal citations omitted).)
5

Regarding ‘834 Patent, Defendant identified “several claim limitations” disclosed on the IPM Website (see Claims
7, 8, 9, 11, and 12), regarding “phenology models” (“crop growth models”), “a degree day insect model”, and “plant
disease models” and asserted these claim limitations were absent from the patent examination record, despite being
material to “the apparatus claim 1.” (Doc. 54 at 33-34.)
6

9

1

these limitations relating to obtaining and using a ‘rule for controlling material dispensing’

2

wherein the rule is ‘retrieved from a location on the Internet.’”).) Thus, Plaintiff “considered this

3

limitation as key to overcoming the prior art considered by the Examiner.” (Id. at 35-36) (“The

4

IPM Website is material prior art because [Plaintiff] relied on other portions of the IPM Website

5

to oppose one of the obviousness rejections raised by the Examiner.”).)

6

Defendant identified “the particular claim limitations, or combination of claim limitations

7

that are supposedly absent from the information of record” and alleged its but-for materiality.

8

Exergen, 575 F.3d at 1328, 1329. The Court finds Defendant successfully pleaded the materiality

9

requirement alleging the Williams Paper and IPM Website information as material.

10

2. The State of Mind Requirement

11

Plaintiff’s motion to dismiss focuses on the state of mind requirement and the particularity

12

required to allege “specific intent to deceive.” Plaintiff argues Defendant’s allegations failed to

13

plead facts from which the Court may reasonably infer a specific intent to deceive because

14

Plaintiff disclosed the references at issue. Plaintiff asserts the Williams Paper and IPM Website

15

were disclosed to the PTO because “they [were] cited for the Examiner and the world to see in the

16

text of the patent specification itself [:]”

17
18
19
20
21
22
23
24
25
26
27
28

(See Doc. 55 at 4) (emphasis in the original).) Therefore,
no one could reasonably infer that a person specifically intended to
deceive by giving the Examiner a URL and a citation—disclosing
them in the most open way possible by putting them in the text of
the patent itself.
10

1

(Doc. 55 at 5.) Plaintiff does not dispute noncompliance with USPTO rule requiring patent

2

applicants to provide printed copies to the Examiner. (Id.) Instead Plaintiff maintains that by

3

incorporating the references into the “Detailed Description of the Invention section of the patent

4

specification” itself (see Doc. 61 at 13), it negates an intent to deceive. (Doc. 55 at 5.) Plaintiff

5

contends that “If anything, what they did to disclose the references was more obvious and open

6

than putting the references in an information disclosure statement (IDS). . .” (Id. at 9.)

7

Accordingly, “even if the form of that disclosure breaks administrative rules,” the Court cannot

8

reasonably infer an intent deceive based on Defendant’s alleged facts. In response, Defendant

9

asserts that Plaintiff deliberately disregarded the “basic procedures mandated by regulation” and

10

despite “knowing the requirements of [the] rules” “only cited to the Williams Paper and IPM

11

Website in a location the examiner would not have been alerted to look for material prior art.”

12

(Doc. 61 at 14.) Defendant asserts that Plaintiff did not disclose the references as material prior

13

art during the “prosecution of the ‘810 and ‘834 Patents” and “affirmatively represented to the

14

examiner that the prior art [, the Williams Paper and IPM Website,] did not disclose information”

15

relevant to the examiner’s assessment of novelty and obviousness. (Id.)

16

B. Defendant’s allegations support an inference of a specific intent to deceive.

17

1. Rule 9(b): Pleading Knowledge

18

Pursuant Rule 9(b), a pleading of inequitable conduct must also “include sufficient

19

allegations of underlying facts from which a court may reasonably infer that a specific individual

20

(1) knew of the withheld material information or of the falsity of the material misrepresentation,

21

and (2) withheld or misrepresented this information with a specific intent to deceive the PTO.”

22

Exergen, 575 F.3d at 1328–29. “A reasonable inference is one that is plausible and that flows

23

logically from the facts alleged, including any objective indications of candor and good faith.”

24

Exergen, 575 F.3d at 1329 n.5.

25

Plaintiff does not dispute knowing the IPM Website and Williams Paper contained

26

material information. In fact, Plaintiff’s argument, to some extent, concede knowledge (and

27

materiality). The essence of Plaintiff’s argument is that the in-text citations provided in the patent

28
11

1

specification, referenced the IPM Website and Williams Paper; thus disclosed the material

2

information to the PTO. Moreover, there is no duty to disclose information that is not material.

3

37 C.F.R. § 1.56 (“There is no duty to submit information which is not material to the

4

patentability of any existing claim.”) Plaintiff does not dispute owing the duty of disclosure to the

5

PTO regarding the IPM Website and Williams Paper. Despite these minor concessions, the Court

6

turns to the pleading and addresses the “knowledge” prong.

7

To sufficiency plead knowledge, Defendant’s pleading must provide a factual basis to

8

infer Plaintiff owed a duty of disclosure in prosecuting the Asserted Patents and knew of the

9

alleged material information disclosed in the IPM Website and Williams Paper. See Exergen, 575

10

F.3d at 1327. Defendant’s pleading sets forth the following facts: Plaintiff “knew the particular

11

contents of [the Williams Paper and IPM Website]” because “in the initial patent application,

12

[Plaintiff] included citations to both documents in the specification to support a portion of the

13

description of their alleged invention.” (Doc. 61 at 5-6) (see also Doc. 54 at 34).) “[T]hen, many

14

years later, after two of the patents-in-suit had issued, [Plaintiff] pointed to an archived version of

15

the IPM Website and submitted a copy of the Williams Paper for the first time to overcome an

16

examiner’s rejection of newly submitted patent claims.” (Id.) (see also Doc. 54 at 39).) The Court

17

finds that Defendant’s pleading alleges facts that support a reasonable inference that Plaintiff

18

knew of the material information contained in the Williams Paper and IPM Website.

19

2. Rule 9(b): Reasonable Inference

20

Plaintiff argues the pleading lacks sufficient facts to reasonably infer a specific intent to

21

deceive. Foremost, the Court finds Plaintiff’s argument unavailing because it appears to

22

misconstrue Rule 9(b) pleading standards with Defendant’s clear and convincing burden at trial.

23

“In deciding a motion to dismiss an inequitable conduct claim, the level of scrutiny applied to the

24

pleadings does not appear to be so exacting as to require clear and convincing evidence or

25

meeting the single-most-reasonable-inference burden.” Exergen, 575 F.3d at 1326-27.

26

Rule 9(b) governs pleading sufficiency which requires a pleading of inequitable conduct

27

to “include sufficient allegations of underlying facts from which a court may reasonably infer that

28

a specific individual . . . withheld or misrepresented this information with a specific intent to
12

1

deceive the PTO.” Exergen, 575 F.3d at 1328–29 (emphasis added). In other words, the pleading

2

party “must allege facts from which it is plausible that the [patent] applicant had an intent to

3

deceive.” Human Genome Scis., Inc. v. Genentech, Inc., No. 2:11-CV-6519-MRP, 2011 WL

4

7461786, at *3 (C.D. Cal., 2011). Rule 9(b) does not require a pleading party to allege facts

5

“supporting the conclusion that specific intent to deceive is the single most reasonable inference

6

to be drawn from the factual allegations.” Pensmore, 609 F. Supp. 3d at 1104 (emphasis added);

7

see also Hangzhou, 2016 WL 10518582, at *2 (quotations omitted)). At this stage of pleading,

8

Rule 9(b) only requires Defendant to “allege facts sufficient to raise a reasonable inference of

9

specific intent to deceive.” Pensmore, 609 F. Supp. 3d at 1104.

10

Regarding a reasonable inference, “[t]he inference need not be the most reasonable

11

inference, but merely a reasonable inference beyond the mere possibility that the applicant had an

12

intent to deceive. Human Genome, 2011 WL 7461786, at *3. “[T]he mere fact that an applicant

13

omitted a piece of prior art is inadequate by itself” to infer an intent to deceive. Id. “In that case,

14

intent to deceive is a mere ‘possibility’ because that fact is ‘merely consistent with’ intent to

15

deceive’” and “stops short of showing that intent to deceive is plausible.” Id. Thus, “[a]

16

reasonable inference is one that is plausible and that flows logically from the facts alleged,

17

including any objective indications of candor and good faith.” Exergen, 575 F.3d at 1329 n.5.

18

a. Duty to Disclose

19

Rule 1.56(a) requires a duty to disclose all information known to be material to

20

patentability to the PTO. “The duty to disclose . . . is deemed to be satisfied if all information

21

known to be material to patentability of any claim issued in a patent was cited by the Office or

22

submitted to the Office in the manner prescribed by §§ 1.97(b) – (d) and 1.98.” 37 C.F.R § 156.

23

These Sections requires an applicant to disclose known material information in the form of an

24

Information Disclosure Statement (IDS). “There is no duty to submit information which is not

25

material to the patentability of any existing claim.” 37 C.F.R § 156(a). “[N]o patent will be

26

granted on an application in connection with which fraud on the Office was practiced or

27

attempted or the duty of disclosure was violated through bad faith or intentional misconduct.” Id.

28
13

1

As previously discussed, Plaintiff does not directly dispute the materiality of the Williams

2

Paper or IPM Website. Nor does Plaintiff dispute knowledge of the Williams Paper and IPM

3

Website. Thus, by admittance, or acquiescence, Plaintiff concedes that the references are material

4

to the patentability of the Asserted Patents. Thus, Plaintiff was required to disclose the Williams

5

Paper and IPM Website information to the PTO. Sections 1.97 and 1.98 require an applicant to

6

disclose material information by means of an Information Disclosure Statement. Plaintiff

7

included an IDS but omitted the Williams Paper and IPM Website information from the IDS. By

8

the plain language of section 1.56(a), Plaintiff did not disclose material information to PTO.

9

Moreover, despite knowing the requirements, Plaintiff included a citation to both references in the

10

text of the patent application and “at no time before or during the prosecution of the ‘810 and

11

‘834 Patents . . . disclose the references as material prior art, bring them to the examiner’s

12

attention as such, or provide the examiner with copies of them.” (Doc. 61 at 14) (see generally

13

Doc. 54 at 38-40).)

14

Plaintiff argues that a finding of intent to deceive is unreasonable or illogical considering

15

in-text citations were provided. The Court disagrees. “[A]n inference of intent to deceive is not

16

illogical where. . . a patentee, had disclosed information about a . . . patent, [but] omitted material

17

nonpatent information related to the disclosed patent.” Hangzhou Chic, 2016 WL 10518582, at

18

*6. Plaintiff provided in-text citations but “repeatedly omitted [the Williams Paper and IPM

19

Website] from their Information Disclosure Statements that they represented to the PTO listed all

20

material prior art known to [Plaintiff and] . . . affirmatively told the patent examiner that nothing

21

in the prior art disclosed “fixed-proximity sensors” and “internet-retrieved irrigation rules” when

22

they knew those technologies were disclosed in the documents they had withheld.” (Doc. 61 at

23

5.) In addition, while prosecuting the ‘810 and ‘834 Patents, Plaintiff “submitted numerous

24

patent claims that recited features disclosed in the Williams Paper and IPM Website,” and “at no

25

point did they disclose those references as prior art in an IDS, or present copies of either reference

26

to the examiner as they were required to do under their duty of candor.” (Doc. 61 at 10.)

27
28

Considering the omission of Williams Paper and IPM Website from the Information
Disclosure Statements and prior material art section of the Asserted Patents, it is reasonable to
14

1

infer an intent to deceive the PTO. Based on the alleged facts that Plaintiff had knowledge of the

2

Williams Paper and IPM Website, knowledge of their materiality, knowledge of the USPTO rules

3

and regulations requiring disclosure, yet omitted the Williams Paper and IPM Website from the

4

IDS, and subsequently failed to identify the Williams Paper and IPM Website as prior material

5

art, it is plausible that Plaintiff withheld the Williams Paper and IPM Website information from

6

the PTO with a specific intent to deceive. “While intent to deceive the PTO may be found as a

7

matter of inference from circumstantial evidence, circumstantial evidence cannot indicate merely

8

gross negligence.” Molins, 48 F.3d at 1181. “[C]ourts must view the involved conduct ‘in light

9

of all the evidence’ and must then determine whether that conduct in its totality manifests a

10

sufficiently culpable state of mind to warrant a determination that it was inequitable.” Id.

11

(quoting Consolidated Aluminum Corp. v. Foseco Int’l, Ltd., 910 F.2d 804, 809 (Fed. Cir. 1990)).

12

Plaintiff’s omission “makes the inference not merely logical but plausible” that “these

13

documents were withheld when they would have precluded issuance [of the Asserted Patents], but

14

selectively presented when they were needed to establish patentability.” See Pensmore, 609 F.

15

Supp. 3d at 1104 (finding the party’s alleged knowledge and concealment of material information

16

support “an inference concerning intent to deceive.”)). Moreover, the IPM Website citation that

17

Plaintiff provided was a URL homepage link that included links to both material and immaterial

18

information. Plaintiff’s citation did not provide a direct link to the referenced material

19

information. Taken the totality of the allegations, inferring an intent to deceive is reasonable.

20

Lastly, though Plaintiff’s contention that in-text citation was an administrative misstep

21

and not an intent to deceive the PTO is also plausible. At the pleading stage the inference of

22

inequitable conduct need not be “the single most reasonable inference” drawn from the alleged

23

facts. Exergen, 575 F.3d at 1329 n.5. Thus, Defendant must merely plead facts sufficient to raise

24

a reasonable inference of specific intent to deceive. Taking the allegations in the light most

25

favorable to Defendant, and “acknowledging the Federal Circuit’s guidance that direct evidence

26

of intent is rare,” (Pensmore, 609 F. Supp 3d at 1104) the Court concludes that Defendant has

27

pleaded sufficient facts from which a reasonable inference of intent to deceive may be drawn.

28
15

1

V.

CONCLUSION

2

For reasons discussed, the Court finds Defendant’s pleading of inequitable conduct

3

(Doc. 54) satisfies the Rule 9(b) pleading requirements. According, Plaintiff’s motion to dismiss

4

Defendant’s inequitable conduct counterclaim is DENIED.
