INTRODUCTION
This matter is before the Court on a motion for summary judgment of
non-infringement (Doc. No. 89) and a motion to exclude (Doc. No. 108) brought by
Defendant Stealth Cam, LLC (“Stealth Cam”). For the reasons set forth below, the Court
grants in part and denies in part the motion for summary judgment and grants in part and
denies in part the motion to exclude.

BACKGROUND
On February 1, 2012, Plaintiff Larry Holmberg (“Holmberg”) filed this lawsuit
against Stealth Cam, alleging infringement of U.S. Patent No. 7,880,793, entitled
“Camera with Mounting Rail” (the “’793 Patent”). (Doc. No. 1.) On August 17, 2011,
Holmberg amended his Complaint, adding a claim for infringement of U.S. Patent
No. 6,556,245, entitled “Game Hunting Video Camera” (the “’245 Patent”). (Doc.
No. 25.) On January 17, 2012, Holmberg filed a Second Amended Complaint, adding
claims for infringement of U.S. Patent No. 8,045,038, entitled “Video Camera with
Mount” (the “’038 Patent”), and U.S. Patent No. 8,059,196, entitled “Camera for
Mounting” (the “’196 Patent”). (Doc. No. 42, Second Am. Compl.) 1
The four patents-in-suit all relate to a video camera with a mounting apparatus and
share the same specification. 2 The Court refers to them collectively as the “Holmberg
Patents.” Holmberg is the sole inventor of the Holmberg Patents, and describes the
invention in the ’245 Patent as follows:

1

The patents-in-suit are included as exhibits to the Second Amended Complaint;
the ’793 Patent is attached as Exhibit A; the ’245 Patent is attached as Exhibit B; the ’038
Patent is attached as Exhibit C; and the ’196 Patent is attached as Exhibit D. All future
citations to the patents in this case refer to these exhibits.
2

The ’245 Patent issued on April 29, 2003. (’245 Patent at 1.) Holmberg filed the
application for the ’793 Patent on May 29, 2009, as a continuation of an application that
was related to the ’245 Patent application. (’793 Patent at 1.) Holmberg filed the
application for the ’038 Patent on October 1, 2009, as a continuation of the same
application for the ’793 Patent. (’038 Patent at 1.) Holmberg filed the application for the
’196 Patent on December 3, 2008, as a continuation of the same application for the ’793
Patent. (’196 Patent at 1.)

2

This invention relates to a design of a video camera for recording
game hunting. More specifically it relates to a video camera design that is
mountable on a weapon so a hunter can record what he or she sees as he or
she is hunting without the help of a third party and without the limitations
of related art.
(’245 Patent, c. 1, ll: 15-20.)
Stealth Cam manufactures and sells digital cameras and accessories for outdoor
pursuit applications, including light-weight digital video cameras for use during activities
such as biking, paddling, and snowboarding. (Doc. No. 93 (“Mann Decl.”) ¶¶ 3, 4.) In or
around 2008, Stealth Cam introduced the EPIC Action Sports Video Camera, a portable
digital video camera that can be mounted to various objects, such as helmets, handlebars,
arms, or boots. (Id. ¶ 6.) The accused products include Stealth Cam’s EPIC D1 POV
Video Cam, EPIC HD (High Definition) 1080P, Epic HD 720P, and Epic Wide (the
“Accused EPIC Cameras” or “EPIC Cameras”). (Doc. No. 117 (“Rahlin Decl.”) ¶ 2,
Ex. 1 (“Pl.’s Claim Chart”) at 1.) Stealth Cam also offers various accessories for its
EPIC Cameras, such as adjustable hardware mounts, waterproof housing, hat clip
mounts, strap mounts, tree screws, and shock absorbing pads. (Mann Decl. ¶¶ 8-9.)
Additionally, Stealth Cam offers for sale an accessory that can be used with its EPIC
cameras for viewing images recorded by the camera—the EPIC Viewer. (Id. ¶¶ 14-15.)
The EPIC Viewer is a display screen that connects to the EPIC camera via an A/V cable
that is sold with the camera. (Id.)
On February 8, 2012, Holmberg filed his “Statement of the Case” asserting that
Stealth Cam infringed the Holmberg Patents directly. (Doc. No. 49 at 2 (“Defendant
Stealth Cam, LLC has been and is making, using, selling, offering for sale, and/or
3

importing, without license or authority from [Holmberg], cameras that embody the
invention(s) claimed in the [Holmberg Patents].”).) 3 Specifically in this action,
Holmberg asserts that the Accused EPIC Cameras infringe claims 1-17 of the ’793
Patent, claims 1-10 and 13-20 of the ’038 Patent, claims 1-20 of the ’196 Patent, and
claim 8 of the ’245 Patent.
On February 22, 2012, the Court entered a Pretrial Order establishing various
deadlines in the case. (Doc. No. 49.) On April 1, 2012, Holmberg served his claim chart
(Infringement Contentions). (Pl.’s Claim Chart.) In his claim chart, Holmberg asserts
direct infringement of the Holmberg Patents, but does not assert infringement under the
doctrine of equivalents or inducement. On May 8, 2012, Stealth Cam served its
non-infringement claim chart. (Rahlin Decl. ¶ 3, Ex. 2 (“Def.’s Claim Chart”).) In its
claim chart, Stealth Cam argues, among other things, that its Accused EPIC Cameras do
not contain a mounting rail for mounting the cameras to an object or a display. (Id.
at 4, 5, 9.) Stealth Cam also asserts that it has not made, used, or sold any camera “for
mounting to a functional weapon.” (Id. at 4, 8.)
On February 8, 2013, the Court entered an Amended Pretrial Order, which
provided the following with respect to the deadline for submitting expert reports:
That both parties’ disclosures on which they have the burden of
proof shall be made on or before the latter of July 15, 2013, or 30 days after
a claim construction ruling by the Court. The rebuttal experts’ disclosures
shall be disclosed on or before the latter of August 16, 2013, or 60 days
after a claim construction ruling by the Court.
3

There is no allegation that Stealth Cam indirectly infringed the Holmberg Patents
under 35 U.S.C. § 271(b). (Doc. No. 49 at 2.)

4

(Doc. No. 60 at 7 (emphasis in original).) Subsequently, on May 28, 2013, pursuant to
the joint stipulation of the parties (Doc. No. 83), the Court ordered that the deadlines
regarding expert disclosure be extended as follows: “The deadline for the parties’ expert
disclosure on which the party has the burden of proof shall be August 14, 2013. . . . The
deadline for rebuttal expert disclosure shall be September 18, 2013. . . . The deadline for
completion of expert discovery shall be October 14, 2013.” (Doc. No. 85.) The parties
then agreed to extend the date to exchange expert reports to August 26, 2013. (Rahlin
Decl. ¶ 9, Ex. 8.)
On July 15, 2013, the Court issued its claim construction order. (Doc. No. 87
(“Markman Order”).) On August 26, 2013, Holmberg submitted the expert report of
Fred P. Smith on the issue of infringement. (Doc. No. 103 (“Smith Decl.”) ¶ 5, Ex. A
(“Smith Expert Report I”).) Stealth Cam submitted its expert report on non-infringement
on October 2, 2013. (Doc. No. 92 (“Buckman Decl.”) ¶ 4, Ex. A (“Buckman Expert
Report”).)
Stealth Cam moved for summary judgment on non-infringement, and the hearing
date was ultimately set to occur after a settlement conference in early December 2013.
The parties agreed to a briefing schedule pursuant to which Holmberg’s opposition would
be due November 12, 2013, and Stealth Cam’s reply would be due November 26, 2013.
(Doc. No. 101.) When Holmberg filed his opposition to Stealth Cam’s motion for
summary judgment, it was accompanied by the Declaration of Fred P. Smith, which in
turn included Smith’s August 26, 2013 Expert Report, as well as a supplemental expert

5

report dated November 12, 2013. (Smith Expert Report I; Smith Decl. ¶ 6, Ex. B (“Smith
Expert Report II”).)
The Court considers Stealth Cam’s motion to exclude and motion for summary
judgment below.
DISCUSSION
I.

Motion to Exclude
Stealth Cam moves to exclude: (1) Smith’s November 12, 2013 expert report as

untimely; (2) any theories of infringement under the doctrine of equivalents and indirect
infringement because they were not disclosed in Holmberg’s infringement contentions;
and (3) the infringement theory that the EPIC Viewer accessory combined with the
Accused EPIC Cameras can satisfy the “display” limitation because this theory was not
disclosed in Holmberg’s infringement contentions.
A.

Timeliness

Stealth Cam argues that Smith’s November 12, 2013 expert report is untimely and
should be excluded. In particular, Stealth Cam asserts that the deadline for Holmberg to
submit an expert report on the issue of infringement was August 26, 2013. Stealth Cam
also argues that even if Smith’s November 12, 2013 expert report is properly
characterized as a “rebuttal” report, it was due “within 30 days of [Stealth Cam’s]
disclosures” and, therefore, would have been due on November 1, 2013. See Fed R. Civ.
P. 26(a)(2)(C)(ii).
Holmberg asserts that the November 12, 2013 expert report was timely because
Stealth Cam presented a new non-infringement theory (that its cameras do not infringe
6

because they are not capable of being directly attached to a weapon) in Buckman’s
October 2, 2013 expert report and in its motion for summary judgment. Holmberg
submits that this theory was not set forth in Stealth Cam’s claim chart or during the
Markman hearing. Finally, Holmberg argues that any supplementation must be
completed by the time of pretrial disclosures. See Fed. R. Civ. P. 26(e).
The parties agree that Rule 37 of the Federal Rules of Civil Procedure governs
“Failure to Disclose or Supplement” under Rule 26(a) or (e). Rule 37 provides that the
failure to disclose information under Rule 26(a) or (e) can result in sanctions, including
the exclusion of the information, unless the failure to disclose was substantially justified
or harmless. Fed. R. Civ. P. 37(c)(1).
Here, with respect to the timeliness of Smith’s November 12, 2013 expert report,
the parties debate the implications of, at most, a period of eleven days. Even if Stealth
Cam is correct and Smith’s November 12, 2013 expert report was untimely by eleven
days, this delay, alone, does not warrant the sanction of excluding the report. However,
the Court will discuss Stealth Cam’s motion as it pertains to the alleged inclusion of
newly asserted theories of infringement below.
B.

New Theories

The Court has previously recognized the importance of infringement contentions
and the role they serve in patent cases by requiring a plaintiff “to crystallize its theory of
the case and patent claims.” See In re Vehicle Tracking and Sec. Sys. (’844) Patent
Litig., MDL No. 11-2249, 2012 WL 3776463, at *2 (D. Minn. Aug. 30, 2012) (citing
InterTrust Techs. Corp. v. Microsoft Corp., Civ. No. 01-1640, 2003 U.S. Dist. LEXIS
7

22736, at *8 (N.D. Cal. Nov. 26, 2003)). “[W]hen parties formulate, test, and crystallize
their infringement theories before stating their preliminary infringement contentions, as
the Patent Rules require, the case takes a clear path, focusing discovery on building
precise final infringement or invalidity contentions and narrowing issues for Markman,
summary judgment, trial, and beyond.” Connectel, LLC v. Cisco Sys., Inc., 391 F. Supp.
2d 526, 527 (E.D. Tex. 2005). When confronted with deficient infringement contentions,
the Court may issue “further just orders.” Fed. R. Civ. P. 37(b)(2)(A).
The Pretrial Order in this case required the following:
Plaintiff’s Claim Chart shall identify: (1) which claim(s) of its patent(s) it
alleges are being infringed; (2) which specific products or methods of
defendant’s it alleges literally infringe each claim; and (3) where each
element of each claim listed in (1) is found in each product or method listed
in (2), including the basis for each contention that the element is present. If
there is a contention by Plaintiff that there is infringement of any claims
under the doctrine of equivalents, Plaintiff shall separately indicate this on
its Claim Chart and, in addition to the information required for literal
infringement, Plaintiff shall also explain each function, way, and result that
it contends are equivalent, and why it contends that any differences are not
substantial.
(Doc. No. 60 at 8 (emphasis added).)
Stealth Cam points out that, in his claim chart, Holmberg does not assert indirect
infringement or inducement of infringement, or infringement under the doctrine of
equivalents. Stealth Cam argues, therefore, that the Court should preclude Holmberg
from pursuing any such theory of infringement and exclude expert testimony on the
same. In particular, Stealth Cam objects to the following infringement theories put forth
by Holmberg: (1) that the EPIC Viewer Accessory combined with the Accused EPIC
Cameras can satisfy the “display” limitation; (2) any theory of infringement under the

8

doctrine of equivalents; and (3) any theory of indirect infringement or inducement of
infringement. 4
First, with respect to Holmberg’s theory that the EPIC Viewer Accessory
combined with Accused EPIC Cameras can satisfy the “display” limitation, there is no
dispute that in his claim chart, Holmberg identifies a display located on the Accused
EPIC Cameras. (Pl.’s Claim Chart at 7, 13, 22, 29, 40 & 44.) There is also no dispute
that the display device located on the Accused EPIC Cameras only displays information
about the operation of the camera (such as numeric information regarding image count
and user status) and that it does not display recorded images. (Mann Decl. ¶¶ 12-13;
Doc. No. 102 at 28.) However, in its Markman Order, the Court construed “display” as
“a device capable of displaying recorded images.” (Doc. No. 87 at 16.) Thus, without
use of the EPIC Viewer, there could be no infringement under the Court’s construction.
Holmberg asserts that he advanced the theory involving the use of the EPIC
Viewer in light of the Court’s Markman order, and that he provided timely notice to
Stealth Cam. Holmberg submits that on July 22 and 23, 2013, he questioned Stealth Cam
witnesses on the EPIC Viewer and how it works, and then timely submitted Smith’s
August 26, 2013 Expert Report, which contained the infringement theory for “display”
that involves the use of the EPIC Viewer. (Rahlin Decl. ¶ 2, Ex. 4 (“Mann Dep.”)

4

As an example, Stealth Cam cites to Smith’s opinion that the EPIC Cameras
infringe claim 8 of the ’245 Patent (limitation requiring a bow) through inducement. (See
Smith Report II ¶¶ 67, 80.)

9

at 48-51, 65-67, 74, 83-90; id. ¶ 2, Ex. 5 (“Cheng Dep.”) at 36-37.) Stealth Cam
responded to the new theory in the October 2, 2013 Buckman Expert Report.
The Court agrees with Holmberg that before the Court construed the term
“display” as “a device capable of displaying recorded images,” it was unnecessary for
Holmberg to assert an infringement theory involving the use of the EPIC Viewer in
combination with the camera because Holmberg’s proposed construction for display was
“a device that gives information in a visual form.” Thus, the Court would be inclined not
to exclude the revised theory of infringement. Even so, the issue is moot because, as
discussed below, even considering that theory, the Accused EPIC Cameras do not satisfy
the “display” limitation as a matter of law. (See infra Section II.B.2.)
Second, Stealth Cam argues that the Court should exclude from evidence any
expert opinions or other evidence by Holmberg that supports a theory of infringement
under the doctrine of equivalents or indirect infringement. Stealth Cam points out that
Holmberg’s claim chart does not contain any suggestion that Holmberg intended to assert
indirect infringement, inducement of infringement, or a theory under the doctrine of
equivalents. Then in Smith’s August 26, 2013 expert report, Smith includes one
paragraph wherein he asserts that if the Accused EPIC Cameras do not literally infringe,
“then they would certainly . . . under the doctrine of equivalents have each and every
element of the asserted claims, as there would only be insubstantial differences.” (Smith
Expert Report I ¶ 72.) Mr. Smith’s November 12, 2013 expert report also contains
additional opinions regarding infringement under the doctrine of equivalents and indirect
infringement. (Smith Expert Report II ¶¶ 67, 69, 80.)
10

Holmberg argues that the Court should not exclude his theory of infringement
under the doctrine of equivalents. In particular, Holmberg asserts that he advanced his
theory of infringement under the doctrine of equivalents only after Stealth Cam
advanced, for the first time, a new theory of non-infringement—that its cameras do not
infringe because they are not capable of being directly attached to a weapon—in
Buckman’s October 2, 2013 expert report and its Motion for Summary Judgment on
Non-infringement, a theory Holmberg claims is based on a new claim construction.
The Court concludes that the issue of whether Holmberg’s infringement theory
under the doctrine of equivalents should be excluded is moot because, as explained
below, the Court’s claim construction does not require direct attachment to a weapon.
Finally, the Court considers Stealth Cam’s motion to exclude any theory of
indirect infringement or inducement of infringement. Holmberg argues that the Court
should not exclude his theories of induced infringement because Holmberg provided
sufficient notice of his inducement claims via specific factual allegations supporting
inducement of infringement in his amended complaints. In addition, Holmberg submits
that in his infringement contentions, Holmberg relies on Stealth Cam’s manuals and
promotional materials, and that Holmberg asked questions during depositions related to
inducement. Thus, Holmberg claims, he provided sufficient notice of inducement claims.
The Court disagrees. Other than conclusory allegations, the record does not
demonstrate that Holmberg fully disclosed or suggested that he intended to pursue a
claim for indirect infringement of the Holmberg Patents. In addition, Holmberg did not
disclose any third parties who have directly infringed the Holmberg Patents or how
11

Stealth Cam induced the direct infringer to infringe. Thus, the Court concludes that
Holmberg is properly precluded from pursuing any theory of indirect or induced
infringement.
In sum, with respect to Defendants’ Motion to Exclude, the Court grants in part
and denies in part as follows: the motion is denied except that Holmberg is precluded
from pursuing any theory of indirect or induced infringement.
II.

Motion for Summary Judgment
A.

Legal Standard

Summary judgment is proper if there are no disputed issues of material fact and
the moving party is entitled to judgment as a matter of law. Fed. R. Civ. P. 56(a). The
Court must view the evidence and the inferences that may be reasonably drawn from the
evidence in the light most favorable to the nonmoving party. See Bai v. L & L Wings,
Inc., 160 F.3d 1350, 1353 (Fed. Cir. 1998). A party opposing a properly supported
motion for summary judgment may not rest upon mere allegations or denials, but must
set forth specific facts showing that there is a genuine issue for trial. Anderson v. Liberty
Lobby, Inc., 477 U.S. 242, 256 (1986). As the United States Supreme Court has stated,
“[s]ummary judgment procedure is properly regarded not as a disfavored procedural
shortcut, but rather as an integral part of the Federal Rules as a whole, which are designed
‘to secure the just, speedy, and inexpensive determination of every action.’” Celotex
Corp. v. Catrett, 477 U.S. 317, 327 (1986) (quoting Fed. R. Civ. P. 1).
Defendant moves for summary judgment on Holmberg’s patent infringement
claims. An infringement analysis has two steps. First, the Court determines the meaning
12

and scope of the patent claims asserted to be infringed. Markman v. Westview
Instruments, Inc., 52 F.3d 967, 976 (Fed. Cir. 1995) (en banc), aff’d, 517 U.S. 370
(1996). Second, the Court compares the properly construed claims to the accused
product. Id. Claim construction is an issue of law, and infringement is a question of fact.
Monsanto Co. v. Syngenta Seeds, Inc., 503 F.3d 1352, 1356 (Fed. Cir. 2007). After a
Markman hearing in this case, the Court construed the disputed claim terms in an Order
dated July 15, 2013. (Doc. No. 87.)
The second step, whether literal or under the doctrine of equivalents, involves a
question of fact. Bai, 160 F.3d at 1353. “Literal infringement of a claim exists when
every limitation recited in the claim is found in the accused device, i.e., when the
properly construed claim reads on the accused device exactly.” Cole v. Kimberly–Clark
Corp., 102 F.3d 524, 532 (Fed. Cir. 1996). See also Allen Eng’g Corp. v. Bartell Indus.,
Inc., 299 F.3d 1336, 1345 (Fed. Cir. 2002). “Thus, a literal infringement issue is properly
decided upon summary judgment when no genuine issue of material fact exists, in
particular, when no reasonable jury could find that every limitation recited in the properly
construed claim either is or is not found in the accused device.” Bai, 160 F.3d at 1353.
B.

Stealth Cam’s Motion
1.

Capable of Being Mounted to a Weapon

As an initial matter, Stealth Cam argues that none of the asserted claims of the
Holmberg Patents are infringed as a matter of law because the Accused EPIC Cameras
are not capable of being mounted to a weapon for game hunting. Stealth Cam correctly
points out that, in its Markman Order, the Court ruled that Holmberg “clearly indicated
13

that the scope of [his] invention was limited to a video camera capable of being mounted
to a weapon for use in game hunting.” (Doc. No. 87 at 9.) Stealth Cam argues that the
Accused EPIC Cameras, as they are made and sold by Stealth Cam, cannot be mounted to
a weapon for use in game hunting because they are made and sold with only a mounting
plate attached to the bottom of the cameras, and the mounting plate is not designed to be
attached to anything other than the mounting accessories offered by Stealth Cam. (Doc.
No. 91 at 15.) Stealth Cam further asserts that the mounting plate is not designed to be
attached directly to a weapon. (Mann Decl. ¶¶ 10-11 (“This mounting plate is designed
to be inserted into one of the mounting accessories offered by Stealth Cam.”); Buckman
Expert Report ¶ 37.) Stealth Cam asserts that Holmberg’s infringement theory is,
instead, based on a physical alteration of the Accused EPIC Cameras—requiring the
addition of a mounting device (and possibly other devices) to enable the cameras to be
mounted on a weapon. In particular, Stealth Cam asserts that the Accused EPIC Camera
must be attached to an unidentified structure (some type of mounting device) that is not
part of the camera.
Holmberg asserts that nothing in the Court’s claim construction order requires a
camera to be directly attached to a weapon, but only that any infringing device be
capable of being mounted to a weapon. Moreover, Holmberg asserts that the Holmberg
Patents explicitly define an intermediate means (a mount including a track for receiving a
mounting rail) that is used to attach a camera of the claimed invention to an object, and
that requiring that the camera be directly attached to a weapon would result in a reading
of the asserted Holmberg Patents that would not cover the embodiments disclosed in the
14

patents. Holmberg further argues that the Accused EPIC Cameras are intended to be—
and are in fact capable of—being mounted to a weapon without any alteration. Holmberg
asserts that the cameras can be mounted to weapons using only the mounting hardware
manufactured and sold by Stealth Cam along with its cameras.
The Court reiterates the ruling in its Markman Order that Holmberg limited the
scope of his invention to “a video camera capable of being mounted to a weapon for use
in game hunting.” The Court notes that it did not, however, hold that the claims of the
asserted Holmberg Patents require that the accused cameras be directly attached to a
weapon to infringe. The Court’s construction is consistent with the fact that nothing in
the claims, specifications, or drawings of the Holmberg Patents requires that a camera be
directly mounted to an object, and is further consistent with the fact that the Holmberg
Patents define an intermediate means (namely, a mount including a track for receiving a
mounting rail of the camera) that is intended to be used to mount the camera to an object.
(Smith Expert Report II ¶¶ 13-15, 17-20.) For example, the detailed description of the
’245 Patent contains the following:
The bracket mounted to a barrel 98 of a firearm is illustrated in FIG. 14.
The upper mount member 91 is placed over the top of the barrel 98 of the
firearm. The lower mount member 92 is placed under the barrel 98.
...
As FIG. 14 illustrates, the video camera is attached to the mounting
bracket by sliding the camera mount member 14 into the track of the lower
mount member 92. When the camera mount member 14 is positioned far
enough into the track of the lower mount member 92 it is locked into place.
This is to ensure that the camera will not inadvertently fall off the weapon.
(’245 Patent, c. 5, ll:44-47, 56-61.) Thus, the Court rejects the argument that the
Accused EPIC Cameras must be directly attached to a weapon in order to infringe.
15

The Court turns to the issue of whether the Accused EPIC Cameras are capable of
being mounted to a weapon. Stealth Cam maintains that its Accused EPIC Cameras, as
they are made and sold, cannot be mounted to a weapon for use in game hunting. Again,
Stealth Cam points to evidence that its Accused EPIC Cameras are made and sold only
with a mounting plate attached to the bottom of the cameras; that the mounting plate is
not designed to be attached to anything other than the mounting accessories offered by
Stealth Cam; and that the mounting plate is not designed to be attached to a weapon.
(Mann Decl. ¶¶ 10-11; Buckman Expert Report ¶ 37.) In addition, Stealth Cam asserts
that Holmberg has not identified any weapon having, as an integral part, a mounting
device to which an Accused EPIC Camera could be directly attached.
Holmberg disagrees and argues that the Accused EPIC Cameras are capable of
being mounted to a weapon without any alteration; specifically that the Accused EPIC
Cameras can be mounted to a weapon using mounts that are sold by Stealth Cam along
with and separately from the Accused EPIC Cameras. Holmberg also points to evidence
that: advertisements demonstrate that Stealth Cam’s Accused EPIC Cameras can mount
to various objects, including weapons; Stealth Cam has displayed an Accused EPIC
Camera at a trade show mounted to a bow using EPIC mounting hardware; and, all of the
Accused EPIC Cameras include a mounting rail, demonstrating that the cameras are
intended to be mounted to something. (Smith Report II ¶¶ 5, 6-7 & Ex. 6.) 5 In addition,

5

Stealth Cam objects to much of this evidence on the grounds that the
advertisements relied on appear to have been created by third-parties. Even if the
(continued on next page…)
16

Holmberg puts forth evidence that the Accused EPIC Cameras are sold in kits that
include mounting hardware. (Id. ¶ 10 & Ex. 9.)
Here, Stealth Cam focuses on the fact that the EPIC mounting devices are separate
accessories and claims that they are not part of the structure of the Accused EPIC
Cameras. Instead, Stealth Cam argues that Holmberg’s infringement theory requires the
attachment of other products to the Accused EPIC Cameras (such as a mounting device),
and that such attachment constitutes a modification or alteration that precludes a finding
of infringement. In support, Stealth Cam relies heavily on High Tech Medical
Instrumentation, Inc. v. New Image Industries, Inc., 49 F.3d 1551 (Fed. Cir. 1995). In
High Tech, the Federal Circuit concluded that “a device does not infringe simply because
it is possible to alter it in a way that would satisfy all the limitations of a patent claim.”
Id. at 1555. The Federal Circuit considered a claim relating to a handheld endoscope
designed for use in dental work and comprised of a body member and a camera disposed
in the body member, where the camera could be rotated within the housing. Id. at 1553.
The accused product was a camera fixed within a housing by two set screws that
prevented rotation, but by loosening the screws, the camera could be rotated. Id. The
Federal Circuit reversed the grant of the patent holder’s motion for a preliminary
injunction, holding that “as designed, sold, and intended for use, the [allegedly
infringing] camera is rigidly coupled to its housing. The original and intended operating

challenged evidence were properly excluded, the Court’s decision below would be the
same.

17

configuration of the device must be altered—by loosening the set screws—in order for
the camera to rotate.” Id. at 1555.
In High Tech, the Federal Circuit considered whether: (1) the accused product
was designed to be altered to infringe; (2) there was any reference to the infringing use in
the accused product’s promotional materials; (3) the alteration would serve any
functional purpose not already accomplished by other means; and (4) whether there was
evidence that any user altered the accused product prior to or during actual use. Id. at
1556. Consideration of those factors, here, leads the Court to conclude that fact issues
exist as to whether the use of mounting hardware constitutes a physical alteration of the
cameras. The record contains evidence that Stealth Cam’s Accused EPIC Cameras are
designed and intended to be mountable to a weapon (or another object). While Stealth
Cam submits that the cameras are complete, functional cameras without a mount, there is
also record evidence that could lead a reasonable juror to find that the cameras are not
intended to operate without being mounted to an object. For example, Holmberg has
submitted evidence that the Accused EPIC Cameras are “designed and configured to be
mounted on an Epic mounting accessory.” (Mann Decl. ¶ 11.) In addition, there is
evidence suggesting that the Accused EPIC Cameras, which are small (with “thumb-size”
dimensions) are not intended to be used without mounting the camera to some object, but
instead are designed to be mounted so that the operator has two free hands to engage in
whatever activity is being filmed.
For these reasons, the Court concludes that the use of Stealth Cam’s mounting
hardware to mount the Accused EPIC Cameras to a weapon does not, as a matter of law,
18

constitute a physical alteration of the Accused EPIC Cameras so as to preclude
infringement. Instead, there is sufficient evidence in the record to lead a reasonable juror
to conclude that the use of mounting hardware to mount an Accused EPIC Camera to a
weapon does not constitute a physical alteration of the camera. 6
In light of the determination that the Holmberg Patents do not require the camera
to be directly mounted to a weapon, and viewing the evidence in the light most favorable
to Holmberg, a reasonable finder of fact could also conclude that the Accused EPIC
Cameras are “capable of being mounted to a weapon.” Therefore, Stealth Cam’s motion
for summary judgment as to this claim limitation is denied.
2.

Display

Stealth Cam argues that numerous asserted claims of the Holmberg Patents are not
infringed as a matter of law because the Accused EPIC Cameras do not contain a display
device capable of displaying recorded images. Specifically, the “display” or “liquid
crystal display” limitation appears in the following asserted claims: claims 1-17 of the
’793 Patent; claims 1-9, 16, 20 of the ’038 Patent; and claims 10-19 of the ’196 Patent.
The Court previously construed the meaning of the term “display” as it appears in
the asserted claims as “a device capable of displaying recorded images.” (Doc. No. 87

6

Stealth Cam also argues that the Accused EPIC Cameras include a “mounting
plate” located on the bottom of the camera that is designed to be inserted into an EPIC
mounting accessory, not a weapon. (Mann Decl. ¶ 11.) However, as discussed above,
the claims do not require that the camera be directly attached to the weapon.

19

at 16.) In addition, the term “liquid crystal display” as it appears was construed as “a
liquid crystal device capable of displaying recorded images.” (Id.)
There is no dispute that the only display device located on the Accused EPIC
Cameras does not display recorded images; instead, it only displays information about the
operation of the camera (such as numeric information regarding image count and user
status). (Mann Decl. ¶¶ 12-13; Doc. No. 102 at 28.) Even so, Holmberg asserts that the
Accused EPIC Cameras meet the “display” requirement because Stealth Cam offers an
accessory (the EPIC Viewer) that can be used with its Accused EPIC Cameras, making it
capable of displaying recorded images. The EPIC Viewer can be connected to an
Accused EPIC Camera with an A/V cable that is sold with the EPIC Viewer. (Mann
Decl. ¶ 14; Smith Report II ¶ 25.) When connected to the EPIC Camera, the EPIC
Viewer allows a user to preview a picture that the camera is about to capture or allows
the user to review videos or pictures already taken. (Mann. Decl. ¶ 15.)
After careful review of the evidence submitted, the Court concludes that the
Accused EPIC Camera, even when used with the EPIC Viewer, does not satisfy the
“display” limitation as a matter of law. The record contains evidence showing that the
Accused EPIC Cameras are independent and functional products that operate as intended
without an EPIC Viewer. (Id. ¶¶ 15-16; Buckman Expert Report ¶¶ 54-56.) Unlike with
the limitation “capable of being mounted on a weapon” above, the Court concludes that
the High Tech rule applies here because there is no record evidence demonstrating that it
is practicable for users of the Accused EPIC Cameras to use the cameras in conjunction
with the EPIC Viewer to view recorded images while the viewer is mounted to a weapon.
20

There is no dispute that the EPIC Viewer must be connected to the Accused EPIC
Camera by an A/V Cable. To make this connection and maintain it while the camera and
viewer are mounted to a weapon would require additional structure.
Viewing the record in the light most favorable to Holmberg, the Court agrees with
Stealth Cam that there is no genuine issue of material fact with respect to the
infringement of claims containing the “display” or “liquid crystal display” limitation. No
reasonable juror could conclude that the display limitation is found in the Accused EPIC
Cameras. Therefore, the asserted claims that contain the “display” or “liquid crystal
display” limitations are not infringed as a matter of law, and Stealth Cam’s motion for
summary judgment as to the “display” and “liquid crystal display” limitations is granted.
3.

Mounting Rail

Stealth Cam argues that numerous asserted claims of the Holmberg Patents are not
infringed because the Accused EPIC Cameras do not contain a mounting rail for
mounting the camera to a weapon. The following claims contain a “mounting rail for
mounting the camera to a weapon” limitation: claims 1 and 10 of the ’793 Patent; claims
19 and 20 of the ’038 Patent; and claims 1 and 19 of the ’196 Patent. For example:
10. A camera for mounting to a functional weapon, the camera
comprising . . . a mounting rail extending along the housing from the front
end toward the rear end, the mounting rail for mounting the camera to the
functional weapon.
(’793 Patent, c. 7, ll: 3-9.) In addition, several dependent claims incorporate this
limitation. In the Markman Order, the Court construed “mounting rail” to mean “an
elongated structural member with a cross-section shaped to correspond to a track in a

21

mount to permit longitudinal sliding movement into and out of the track in the mount.”
(Doc. No. 87 at 23.)
Stealth Cam relies on its argument that the Accused EPIC Cameras are not capable
of being mounted directly to a weapon, and therefore, that the Accused EPIC Cameras do
not contain a mounting rail for mounting the camera to a weapon. (Doc. No. 91
at 25-26.) Stealth Cam acknowledges that the Accused EPIC Cameras have a mounting
plate attached to the bottom of the cameras that is designed to be coupled to a mounting
device, but maintains that its cameras do not have a mounting device for the attachment
of the cameras to a weapon. Stealth Cam further asserts that Holmberg has not put forth
evidence of any weapon with a mounting device to which the mounting plate of the
Accused EPIC Cameras can be directly attached. (Buckman Expert Report ¶¶ 66-67.)
Stealth Cam argues that to attach an Accused EPIC Camera to a weapon, some
unidentified structure (such as a mounting device) must be attached to the weapon, not
the camera. (Id. ¶¶ 68-69.)
Holmberg disagrees and claims that the Accused EPIC Cameras include a
mounting rail on the bottom of their cameras that is designed to slide into any EPIC
mount. (Doc. No. 102 at 31.) Holmberg asserts that Stealth Cam’s interpretation of
“mounting rail” is inconsistent with the Markman Order, and that the Holmberg Patents
teach the use of an intermediate structure that receives a “mounting rail.”
The Court concludes that Holmberg has submitted sufficient evidence that could
lead a reasonable juror to find that the Accused EPIC Cameras contain a mounting rail.
In particular, Holmberg submits evidence that the Accused EPIC Cameras are capable of
22

being attached to a weapon by using a mounting rail that slides into and out of a track in
the mount. As stated above, the claims do not require a camera to be directly attached to
a weapon. Moreover, the Holmberg Patents provide for the attachment of a camera to an
object through an intermediate structure, such as a mount. Accordingly, Stealth Cam’s
motion for summary judgment as to this claim limitation is denied.
4.

Mount for Receiving a Mounting Rail

Claim 1 of the ’196 Patent and Claim 8 of the ’245 Patent both contain the
following limitation: “a mount for receiving the mounting rail.” Stealth Cam asserts that
although the Accused EPIC Cameras contain a mounting plate attached to the bottom of
the camera that is designed to be coupled to a mounting device, the Accused EPIC
Cameras do not contain a mount for receiving a mounting rail. Stealth Cam further
points out that there is no evidence of any weapon having, as an integral part, a mounting
device to which the Accused EPIC Cameras could be directly attached. In addition,
Stealth Cam maintains that the fact that it is possible to modify or alter the Accused EPIC
Cameras by adding a mount (that is sold separately by Stealth Cam) is not enough to
establish infringement. Thus, Stealth Cam contends that the Accused EPIC Cameras do
not satisfy this limitation as a matter of law.
Holmberg disputes this, again arguing that the claims do not require a camera to
be directly attached to a weapon. Holmberg reiterates that the Holmberg Patents all
demonstrate that a camera of the claimed invention is mounted to an object (i.e., weapon)
through an intermediate means, and therefore that the cameras do not directly attach to a
weapon. Holmberg further asserts that because the Accused EPIC Cameras include
23

mounting rails that attach to mounts (which are sold separately and in kits along with the
cameras), the accused products meet the “mount for receiving the mounting rail”
limitation.
The Court concludes that Holmberg has submitted sufficient evidence that could
lead a reasonable juror to find that the Accused EPIC Cameras contain “a mount for
receiving the mounting rail.” As discussed above, the claims do not require that the
camera be directly attached to a weapon. In addition, there is evidence in the record that
is sufficient to demonstrate that the Accused EPIC Cameras are action cameras, designed
to take video while mounted to something (handle bar, wrist, helmet, weapon, etc.).
Further, there is evidence in the record that is sufficient to demonstrate that the Accused
EPIC Cameras are designed and configured to be mounted to an EPIC mounting
accessory, and that the products would not be operable for their intended use without a
mount. (Mann Decl. ¶ 11.)
For the above reasons, the Court denies Stealth Cam’s motion for summary
judgment as to “mount for receiving the mounting rail” limitation.
5.

Claim 8 of the ’245 Patent

Claim 8 of the ’245 Patent reads as follows:
8.
A video camera recorder in combination with a bow
comprising:
a main camera body having a front and back end;
a bow; and
a means for mounting the main camera body to a counter weight bar
of the bow whereby a hunter can monitor and record a hunt.
(’245 Patent c. 8, ll: 43-49.) Stealth Cam argues that this claim is not infringed, as a

24

matter of law, because the Accused EPIC Cameras: are not combined with a bow;
do not have a means for mounting the main camera body to a counterweight bar of the
bow; and do not have a means whereby a hunter can monitor and record a hunt.
Claim 8 of the ’245 Patent contains the following limitation: “A video camera
recorder in combination with a bow.” There is no dispute that the Accused EPIC
Cameras, as made and sold by Stealth Cam, are not combined with a bow. Even so,
Holmberg asserts that Stealth Cam induced infringement of claim 8 by advertising that
the Accused EPIC Cameras are capable of being mounted to a bow and because Stealth
Cam knew that customers using the Accused EPIC Cameras mounted to a bow would
infringe. In support, Holmberg points to evidence of Stealth Cam’s trade show
demonstrations, video advertising, and advertising on its packaging for its EPIC products.
“Whoever actively induces infringement of a patent shall be liable as an
infringer.” 35 U.S.C. § 271(b). Holmberg claims Stealth Cam induced customers to
infringe the ’245 Patent. The elements of inducement are: (1) direct infringement by a
third party; (2) the inducer’s “knowledge of acts alleged to constitute infringement”; and
(3) the inducer’s “specific intent and action to induce infringement.” DSU Med. Corp. v.
JMS Co. Ltd., 471 F.3d 1293, 1305-06 (Fed. Cir. 2006). “Hypothetical instances of direct
infringement are insufficient to establish vicarious liability of indirect infringement.”
ACCO Brands, Inc. v. ABA Locks Mfr. Co., Ltd., 501 F.3d 1307, 1313 (Fed. Cir. 2007).
The Court concludes that Holmberg’s claim of infringement of claim 8 of the ’245
Patent fails for two primary reasons. First, as discussed above, Holmberg did not assert
indirect infringement in its claim chart. Therefore, Holmberg is precluded from asserting
25

that theory of infringement now. Second, Holmberg has not presented sufficient
evidence that Stealth Cam induced a third party to engage in direct infringement of claim
8 of the ’245 Patent. Accordingly, the Court grants Stealth Cam’s motion for summary
judgment as to this limitation.
Because Holmberg’s infringement claim as to claim 8 of the ’245 Patent fails as a
matter of law, the Court need not address Stealth Cam’s additional arguments on
non-infringement. Even so, the Court notes that claim 8 of the ’245 Patent also contains
the following limitation: “whereby a hunter can monitor and record a hunt.” In the
Markman Order, the Court construed this term as “whereby a hunter can use the camera
to view and record a hunt.” (Doc. No. 87 at 12.) The Court already concluded that, as a
matter of law, the Accused EPIC Cameras do not contain a “display” capable of
displaying recorded images. Therefore, it follows that the Accused EPIC Cameras do not
contain the limitation “whereby a hunter can monitor and record a hunt.” 7
ORDER
Therefore, IT IS HEREBY ORDERED that:

Holmberg also asks the Court to clarify the scope of the Markman Order to
remove any implication that the scope of the invention in claim 10 of the ’038 Patent and
claims 1 and 10 of the ’196 patent is limited to a “video camera capable of being
mounted to a weapon for use in game hunting.” The Court defers ruling on this issue
until the issue can be more fully addressed by both parties.
