MEMORANDUM OPINION AND ORDER

Before the Court is Plaintiff-Counterclaim Defendant DuraPlas, LP’s
(“DuraPlas”) Motion for Protective Order (the “Motion”) (Doc. No. 167 (unsealed
version) and Doc. No. 169-1 (sealed version)), Appendix in Support of Plaintiff
DuraPlas, LP’s Motion for Protective Order (Doc. Nos. 168-1–168-10 (unsealed
exhibits) and Doc. Nos. 169-2–169-3 (sealed exhibits)) (the “Appendix”), Defendant-
Counterclaim Plaintiff DiversiTech Corporation’s (“DiversiTech”) Opposition to
DuraPlas, LP’s Motion for Protective Order (Doc. No. 175) (the “Opposition”), and
Plaintiff DuraPlas, LP’s Reply in Support of Its Motion for Protective Order (Doc. No.
186) (the “Reply”). The Court has carefully considered the Motion, Appendix,
Opposition, and Reply, as well as the applicable law and the relevant portions of the
record. The Court finds that DuraPlas has established that the requested relief is
warranted. Accordingly, the Court GRANTS the Motion.
I. Background
This is a patent infringement case. Among other things, DuraPlas seeks a

declaratory judgment that its Version 1 PolarPad products did not infringe certain
patents owned by DiversiTech. In response, DiversiTech has asserted, among other
things, that the Version 1 PolarPad products did infringe certain DiversiTech patents.
Notably, DuraPlas says that it is no longer selling the Version 1 PolarPad products.

As relevant here, DuraPlas filed its Motion requesting a protective order
“allowing it to engage in a targeted recycling of its withdrawn Version 1 PolarPad
inventory” and “preventing DiversiTech from using unfounded spoliation accusations
to interfere with DuraPlas’s good-faith business operations.” Doc. No. 167 at 4 (all
citations to CM/ECF page numbers unless otherwise noted). DuraPlas explains that it

“has begun recycling its excess Version 1 PolarPad inventory by removing the isolated
Version 1 pads from its warehouse, regrinding them, and recasting the material into
other products.” Id. It says it “is undertaking this process because continued storage of
obsolete Version 1 inventory imposes substantial and unnecessary warehousing and

handling costs, and because DuraPlas needs that space for its Version 2 operations.”
Id. at 4–5. According to DuraPlas, it “has ensured that all information relevant to the
disputed rib structure and other asserted patent issues is preserved” by “document[ing]
the Version 1 inventory through internal records and a third-party auditor” as well as
“preserv[ing] representative physical samples of Version 1 pads sufficient for any

legitimate discovery or expert examination[.]” Id. at 5. DuraPlas specifically requests
“a protective order (1) confirming that its documented recycling of Version 1 inventory
does not violate any preservation duty; (2) prohibiting DiversiTech from demanding

that DuraPlas indefinitely warehouse all Version 1 PolarPads; and (3) barring
DiversiTech from using DuraPlas’s recycling of Version 1 PolarPad inventory as a basis
for sanctions, adverse inferences, or any other litigation advantage in this action.” Id.
at 6. In support of this relief, DuraPlas argues it has satisfied its duty to preserve
evidence by retaining representative samples and documents related to its Version 1

PolarPad inventory, there is no basis for concluding its proposed recycling stems from
bad faith, and the recycling would not prejudice DiversiTech. Id. at 13–17.
In its Opposition, DiversiTech argues the Motion should be denied and
DuraPlas “should not be permitted to continue to destroy evidence without providing

basic information about what has already been destroyed[.]” Doc. No. 175 at 4.
Alternatively, it says, the Court should deny the motion “without prejudice to renewal
but only after (a) DuraPlas provides evidence identifying the specific dates it began
destroying V1 inventory and the number and types of V1 pads destroyed, (b)

DiversiTech is provided with the opportunity to test that evidence, as well as the
statements made in the declaration of Paul Phillips submitted with DuraPlas’s motion,
via deposition, and (c) DuraPlas permits DiversiTech to inspect the remaining V1 pads
it has not yet destroyed so that the parties may coordinate on which V1 pads should
be maintained as representative samples.” Id. (emphasis original). DiversiTech argues

DuraPlas’s “unilateral” and “undisclosed” decision to destroy its V1 inventory was
improper, that DuraPlas has not shown good cause because the evidence DuraPlas
provides with its Motion is “insufficient and wholly conclusory,” and that DuraPlas

“does not seek this protective order with clean hands.” Id. at 10–16.
In its Reply, DuraPlas highlights how, in its separate filing seeking a temporary
restraining order, DiversiTech asked the Court to order DuraPlas “to ‘destroy or
surrender’ any remaining V1 PolarPads[.]” Doc. No. 186 at 4 (quoting DiversiTech’s
Reply in Support of Its Emergency Motion for Reconsideration of Order Denying

Temporary Restraining Order and Preliminary Injunction and Brief in Support (Doc.
No. 181 at 9)) (emphasis added). As explained by DuraPlas, “[w]ithin the course of
one week, DiversiTech has asked this Court to order DuraPlas to destroy the same V1
inventory even as it opposes DuraPlas’s request for a protective order allowing DuraPlas

to recycle that same inventory pursuant to a documented preservation protocol.” Id.
(emphasis original). DuraPlas argues the separate request to order destruction of the
V1 PolarPads “reveals the true nature” of DiversiTech’s opposition, which is “not
grounded in preservation concerns, but in an effort to control the manner in which

DuraPlas operates its business and to impose unnecessary burdens that hinder
DuraPlas’s ability to compete with DiversiTech.” Id. at 5–6. DuraPlas also argues
DiversiTech “fails to identify any evidence that will be lost or any prejudice,”
DiversiTech “has not shown any entitlement to inspect DuraPlas’s ‘facilities,’”
DiversiTech is not entitled to “dictate DuraPlas’s preservation methodology or control
sample selection,” and DuraPlas “has no duty to disclose business ‘secrets’” including
its plan to transition to a second version of the PolarPad. Id. at 6–13.

II. Standard of Review
Under Federal Rule of Civil Procedure 26(c)(1), a party “may move for a
protective order in the court where the action is pending” to protect it “from . . . undue
burden or expense” upon a showing of “good cause” and with a “certification that the

movant has in good faith conferred or attempted to confer with other affected parties
in an effort to resolve the dispute without court action.” “Rule 26(c)’s requirement of
a showing of good cause to support the issuance of a protective order indicates that
‘[t]he burden is upon the movant to show the necessity of its issuance, which
contemplates a particular and specific demonstration of fact as distinguished from

stereotyped and conclusory statements.’” In re Terra Int’l, Inc., 134 F.3d 302, 306 (5th
Cir. 1998) (quoting United States v. Garrett, 571 F.2d 1323, 1326 n.3 (5th Cir. 1978)).
III. Analysis
After patent infringement lawsuits commence, alleged infringers—even in the

absence of orders expressly permitting them to do so, but only in the absence of
preliminary injunctions—may continue to sell allegedly infringing products. While
preliminary injunctions may be denied for various reasons, it is notable that, while
there is a public interest in the protection of patent rights, there is a counterbalancing
right to compete that may outweigh the interest in the protection of patent rights. See

Illinois Tool Works, Inc. v. Grip-Pak, Inc., 906 F.2d 679, 684 (Fed. Cir. 1990)
(“Recognizing a public interest in the protection of patent rights, the district court
deemed that interest counterbalanced in this case by Grip–Pak’s continuing right to

compete, which must be seen as legitimate at this motion stage in view of ITW’s
‘remote’ showing of likelihood of success in proving infringement at trial. We find no
error in that approach in this case.”). As applied here, the Court has not granted any
injunction in this case. Thus, it is not disputed that DuraPlas may dispose of the
allegedly infringing products through sales.

Here, however, DuraPlas does not seek to dispose of the allegedly infringing
products through sales but instead to destroy most (though not all) of its allegedly
infringing products. In many cases the patent owner seeks an order requiring just that,
the destruction of infringing products. See Bose Corp. v. JBL, Inc., 112 F. Supp. 2d 138,

170 (D. Mass. 2000), aff’d, 274 F.3d 1354 (Fed. Cir. 2001) (“Although some courts
have issued injunctions ordering the destruction of remaining infringing inventory, . . .
this remedy seems extraordinarily wasteful.”) (citation omitted). But DiversiTech
opposes this relief.

The Court finds good cause to allow DuraPlas to destroy all but representative
samples of the Version 1 PolarPad products pursuant to Rule 26(c)(1). In particular,
the Court finds DuraPlas has met its burden to show the necessity of a protective order
to protect it from undue burden and expense given particular and specific evidence
indicating unnecessary costs storing rather than recycling its Version 1 PolarPad

inventory. See Doc. No. 169-2 at 4–5, ¶14. Storing this inventory rather than recycling
it is burdensome and expensive given how the warehouse space storing it displaces a
substantial volume and associated sales of non-accused inventory, the substantial cost

of renting additional space to store it, the substantial cost of handling and supervising
it, and the substantial cost of buying new material for other products rather than using
recycled material. Id. Storing this inventory is also unnecessary given the lack of any
unique aspect of it in the context of this case and the circumstances. This is a patent
infringement case dependent upon the design of the allegedly infringing products rather

than, for example, manufacturing defects, and, regardless, DuraPlas has committed to
retain relevant documents and samples. DuraPlas has also provided a certification as
well as evidence that it has in good faith conferred with DiversiTech in an effort to
resolve this dispute without the Court’s action. See Doc. No. 167 at 19; Doc. Nos. 168-

9 & 168-10 (counsel correspondence). In short, DuraPlas has met all the requirements
for a protective order.
Neither party cites any opinion granting or denying the requested relief in the
present type of case—a patent infringement case. Instead, the parties dispute the

applicability of a district court’s grant of a protective order allowing destruction of “the
majority of the product” in a “putative product-liability class action,” where the
defendant “discovered that such products were potentially contaminated with beetle
parts and/or beetle larvae.” See Brandner v. Abbott Lab’ys, Inc., No. CIV.A. 10-3242,
2011 WL 2457683, at *1 (E.D. La. June 16, 2011), order amended on reconsideration, No.

CIV.A. 10-3242, 2011 WL 4853384 (E.D. La. Oct. 13, 2011). In that case, the court
recognized that “[c]ourts have not hesitated to issue protective orders . . . when the
cost of maintaining a recalled product poses an undue burden.” Id. at *3. That court

granted the underlying motion subject to a requirement to retain “unopened,
uncompromised units that were recalled” and a commitment by the defendant to work
with the plaintiff’s counsel “to retain the best representative sample.” Id. at *4. Here,
the Court similarly finds that issuing a protective order allowing destruction of V1
PolarPad products in this case, a patent infringement case, is appropriate because the

cost of maintaining those products poses an undue burden and the accused infringer
has committed to retain representative samples and documents related to those
products. Unlike in Brandner, however, the Court will not require agreement on
representative samples and documents given that this is a patent infringement case

related to the design of the accused products rather than a product-liability class action
related to alleged manufacturing defects.
With respect to Brandner, DiversiTech identifies three ways to distinguish the
case. First, it points out, “in contrast to Brandner, no governmental agency has

recommended the destruction of DuraPlas’s inventory.” Doc. No. 175 at 13. Second,
it says, “unlike the Brandner defendants, DuraPlas has not and does not propose that
it will coordinate with DiversiTech in order to identify representative samples of the
V1 PolarPads[.]” Id. Third, it continues, the initial order in Brandner permitting
destruction “was amended on reconsideration” to note that nothing in the first order

condoned or immunized any alleged spoliation by defendants that occurred before the
issuance date of the first order. Id. at 12, n.6. DiversiTech’s objections related to
Brandner do not withstand scrutiny. First, the lack of a government agency

recommendation to destroy the accused products does not eliminate the unnecessary
cost of storing rather than recycling them. Second, as already discussed, the Court does
not find coordination or agreement on representative samples to be necessary given the
focus on the design of the accused product here. Third, here, the Court similarly has
not condoned or immunized any alleged spoliation that occurred before the issuance

of this Order.
None of DiversiTech’s other objections overcome the Court’s conclusion that
DuraPlas has shown good cause for the requested relief. While DiversiTech desires
information about what DuraPlas has already destroyed, including the dates DuraPlas

began destroying V1 inventory and the number and types of V1 pads already destroyed
as well as deposition testimony related to this information, it can gain that information
and testimony through the normal discovery process. Next, while DiversiTech suggests
it should be entitled to an inspection and coordination related to representative

samples, it has not demonstrated any need for either. In this regard, the Court again
notes that this is a patent infringement case rather than a product-liability class action,
and the Court highlights how DuraPlas’s counsel has specifically represented that
DuraPlas “has preserved representative physical samples of Version 1 pads sufficient
for any legitimate discovery or expert examination[.]” Doc. No. 167 at 5. As for

DiversiTech’s complaint about DuraPlas’s “unilateral” and “undisclosed” decision to
recycle its products, DuraPlas ultimately did disclose to DiversiTech its decision to
recycle V1 pads and it ultimately sought permission to do so through its Motion. Next,

despite DiversiTech’s argument to the contrary, DuraPlas’s evidence is not insufficient
or wholly conclusory; rather, as discussed above, its Appendix identifies specific
burdens and costs. Finally, the Court rejects the idea that DuraPlas seeks the protective
order with unclean hands given the inability of DiversiTech to identify any potential
unique aspect of any destroyed product, and the Court agrees with DuraPlas that

DiversiTech has failed to identify any evidence that has been or will be lost or, more
broadly, any actual prejudice.
Finally, regardless of all the above analysis, the Court finds that DiversiTech
waived its objection to the relief requested in the Motion when it argued the following

in separate briefing in this case:
Specifically, DiversiTech now requests an order . . . . requiring DuraPlas to
destroy or surrender to DiversiTech any V1 PolarPads remaining in
DuraPlas’s possession, custody, or control (including pads returned through
part (d)), with verification by sworn declaration—an obligation that
simply makes enforceable DuraPlas’s existing voluntary representations .
. . .
DiversiTech’s Reply in Support of Its Emergency Motion for Reconsideration of Order
Denying Temporary Restraining Order and Preliminary Injunction and Brief in
Support (Doc. No. 181 at 9) (emphases added).
IV. Conclusion
As explained, DuraPlas has established that the requested relief is warranted. As
a result, the Court hereby GRANTS the Motion as follows. The Court hereby:
(1) confirms that DuraPlas does not violate any preservation duty to the extent
it recycles Version 1 PolarPad inventory while simultaneously preserving
related documentation and representative samples;
(2) confirms that DuraPlas is not required indefinitely to warehouse all Version
1 PolarPads; and
(3)bars DiversiTech from using DuraPlas’s recycling of Version | PolarPad
inventory consistent with the terms of this Order as a basis for sanctions,
adverse inferences, or any other litigation advantage in this action.
SO ORDERED.
Signed July 27", 2026.
