ACOSTA, Magistrate Judge:
Introduction

World Class Technology Corporation (“WCT”) seeks declaratory judgment of
noninfringement of five patents owned by Ormco Corporation (“Ormco”). Ormco asserts a
counterclaim of infringement of its U.S. Patent No. 8,393,896 (“the ‘896 Patent”), a sixth patent now
the subject of this litigation. Relevant to the present motion, Ormco accuses WCT of marketing an

infringing product, the H4 bracket. Ormco now moves for a preliminary injunction to halt sales of
the allegedly infringing H4 bracket. The court concludes that Ormco has not met its burden to
establish a likelihood of success on the merits of its infringement claim. Accordingly, Ormco has
failed to make the showing necessary to justify a preliminary injunction and the motion is denied.
Background
The ‘896 Patent is the latest in a series of patents that cover self-ligating orthodontic bracket
technology. Self-ligating brackets differ from traditional brackets in that they permit attachment of
the wire, known as the archwire, and the bracket without the use of traditional ligatures, such as
rubber bands or additional wires. Instead, the self-ligating bracket features a slot with a sliding
cover that permits an orthodontist to place the archwire in the slot and to secure it in the slot by
sliding the cover into the closed position.
Ormco is well-established in the United States orthodontic market and possesses a loyal
customer base and a positive reputation. Ormco owns several patents that feature self-ligating
bracket technology and has developed a line of brackets known as the Damon brackets, named after
inventor Dr. Dwight Damon. WCT, formerly a manufacturer of Ormco brackets, is now a
competitor of Ormco and produces its own self-ligating bracket, the H4 bracket. According to
WCT, the H4 bracket uses different manufacturing technology that gives it a competitive advantage
over Ormco’s brackets.
Ormco claims that two of its former employees, Dr. Thomas Pitts and Dr. Duncan Brown,
have been instrumental in developing and promoting the H4 bracket, though neither doctor is
currently employed by WCT. Ormco nonetheless attributes much of the harm it has allegedly
suffered as a result of the H4 bracket to the activities of these two individuals. Ormco also alleges

{KPR}

collaboration between WCT and the doctors with regard to promotion of the H4 bracket and
Ormco’s proprietary information. According to Ormco, the H4 bracket’s presence in the market has
caused lost sales, price erosion, and damage to its customer relationships. Ormco does not currently
market a product that embodies the technology covered by the ‘896 Patent.
Legal Standard
The Patent and Trademark Act specifically authorizes a preliminary injunction in a patent
case to prevent infringement pending a ruling on the merits. 35 U.S.C. § 283 (2013). This inquiry
is governed by Federal Circuit law. Hybritech, Inc. v. Abbott Laboratories, 849 F.2d 1446, 1451
n.12 (Fed. Cir. 1988). In the patent context, “[t]he four factors relevant to the district court’s
decision to grant or deny a preliminary injunction are[:] ‘(1) the likelihood of the patentee’s success
on the merits; (2) irreparable harm if the injunction is not granted; (3) the balance of hardships
between the parties; and (4) the public interest.’” Abbott Labs. v. Andrx Pharms., Inc., 473 F.3d
1196, 1200-1201 (Fed. Cir. 2007) (quoting Oakley, Inc. v. Sunglass Hut Int’l, 316 F.3d 1331,
1338-39 (Fed. Cir. 2003)). “Although the factors are not applied mechanically, a movant must
establish the existence of both of the first two factors to be entitled to a preliminary injunction.”
Altana Pharma AG v. Teva Pharms. USA, Inc., 566 F.3d 999, 1005 (Fed. Cir. 2009) (citing
Amazon.com, Inc. v. Barnesandnoble.com, Inc., 239 F.3d 1343, 1350 (Fed. Cir. 2001)). Thus,
“because ‘a movant must establish both a likelihood of success on the merits and irreparable harm
. . . the district court may deny a preliminary injunction based on the movant’s failure to establish
either [likelihood of success on the merits or irreparable harm] without making additional findings
respecting the other factors.’” Texas Instruments Inc. v. Tessera, Inc., 231 F.3d 1325, 1329 (Fed.
Cir. 2000) (quoting Reebok Int’l Ltd. v. J. Baker, Inc., 32 F.3d 1552, 1556 (Fed. Cir. 1994)). Finally,

OPINION AND ORDER

3

{KPR}

“[a] preliminary injunction is a ‘drastic and extraordinary remedy that is not to be routinely
granted.’” National Steel Car, Ltd. v. Canadian Pacific Railway, Ltd., 357 F.3d 1319, 1324 (Fed.
Cir. 2004) (quoting Intel Corp. v. ULSI Sys. Tech., Inc., 995 F.2d 1566, 1568 (Fed. Cir. 1993)).
Discussion
The parties’ respective briefing and arguments make clear that the success of this motion
turns on whether Ormco is likely to succeed on the merits of its infringement claim against WCT
and, more specifically, the court’s construction of “support surface.” Ormco concedes that if the
court adopts WCT’s construction, its infringement claim will fail; WCT concedes that, under its own
construction of “support surface,” the patent is valid on all challenged grounds. It is wellestablished that “the patentee seeking a preliminary injunction in a patent infringement suit must
show that it will likely prove infringement, and that it will likely withstand challenges, if any, to the
validity of the patent.” Titan Tire Corp. v. Case New Holland, Inc., 566 F.3d 1372, 1376 (Fed. Cir.
2009) (emphasis added). Accordingly, upon a finding of noninfringement, the court need not
examine validity.

Principles of Claim Construction

“It is a ‘bedrock principle’ of patent law that ‘the claims of a patent define the invention to
which the patentee is entitled the right to exclude.’” Phillips v. AWH Corp., 415 F.3d 1303, 1312
(Fed. Cir. 2005) (quoting Innova/Pure Water, Inc. v. Safari Water Filtration Systems, Inc., 381 F.3d
1111, 1115 (Fed. Cir. 2004)). The analysis of a patent infringement action involves two steps: (1)
the proper construction of the asserted claim; and (2) a determination of whether the accused method
or product infringes the claims as properly construed. Markman v. Westview Instruments, Inc., 52

F.3d 967, 976 (Fed. Cir. 1995) (en banc), aff’d 517 U.S. 370 (1996). “To ascertain the scope and
meaning of the asserted claims, we look to the words of the claims themselves, the specification, the
prosecution history, and any relevant extrinsic evidence.” Retractable Technologies, Inc. v. Becton,
Dickinson and Co., 653 F.3d 1296, (Fed. Cir. 2011) (citing Phillips, 415 F.3d at 1315-1317).
In construing claim language, the words of a claim “are generally given their ordinary and
customary meaning[.]” Vitronics Corp. v. Conceptronics, Inc., 90 F.3d 1576, 1582 (Fed. Cir. 1996).
The ordinary and customary meaning of a claim term is the meaning that the term would have to a
person of ordinary skill in the art in question at the time of the invention, i.e., as of the effective
filing date of the patent application. Phillips, 415 F.3d at 1313. “In some cases, the ordinary
meaning of claim language as understood by a person of skill in the art may be readily apparent even
to lay judges, and claim construction in such cases involves little more than the application of the
widely accepted meaning of commonly understood words.” Id. at 1314.
The court looks at the words of the claims themselves, both asserted and unasserted. Id.
“[T]he context in which a term is used in the asserted claim can be highly instructive.” Id. For
example, the Federal Circuit has consistently held that interpreting a claim term in a manner that
renders subsequent claim language superfluous is improper. See Stumbo v. Eastman Outdoors, Inc.,
508 F.3d 1358, 1362 (Fed. Cir. 2007) (holding that a definition that renders claim language
superfluous is “a methodology of claim construction that this court has denounced”); see also Merck
& Co. v. Teva Pharms. USA, Inc., 395 F.3d 1364, 1372 (Fed. Cir. 2005) (“A claim construction that
gives meaning to all the terms of the claim is preferred over one that does not do so.”). Similarly,
the doctrine of claim differentiation recites the principle that the limitations in each claim are
presumed to be distinct from one another. See Liebel-Flarsheim Co. v. Medrad, Inc., 358 F.3d 898,

910 (Fed. Cir. 2004) (holding that the presence of a dependent claim that adds a particular limitation
gives rise to a presumption that the limitation in question is not present in the independent claim).
However, the claims “do not stand alone[,]” Phillips, 415 F.3d at 1315, and “must be read
in view of the specification, of which they are a part.” Markman, 52 F.3d at 978. Accordingly, the
specification “is always highly relevant to the claim construction analysis. Usually, it is dispositive;
it is the single best guide to the meaning of a disputed term.” Vitronics, 90 F.3d at 1582. The
specification is especially important because “a patentee may choose to be his own lexicographer
and use terms in a manner other than their ordinary meaning, as long as the special definition of the
term is clearly stated in the patent specification or file history.” Id. As such, “it is always necessary
to review the specification to determine whether the inventor has used any terms in a manner
inconsistent with their ordinary meaning. The specification acts as a dictionary when it expressly
defines terms used in the claims or when it defines terms by implication.” Id.
Although the specification is relevant to claim construction, limitations found only in the
specification are not to be read into the claims if the claim language is broader than the specification.
See Electro Medical Sys., S.A. v. Cooper Life Sciences, 34 F.3d 1048, 1054 (Fed. Cir. 1994)
(“although the specifications may well indicate that certain embodiments are preferred, particular
embodiments appearing in a specification will not be read into the claims when the claim language
is broader than such embodiments”); see also Teleflex, Inc. v. Ficosa N.A. Corp., 299 F.3d 1313,
1327 (Fed. Cir. 2002) (refusing to import a limitation found in the specification even when the
specification disclosed only one embodiment).
In addition to the specification, the court should consult the prosecution history of the patent,
if in evidence. Phillips, 415 F.3d at 1317. Although typically less helpful than the specification,

the prosecution history may demonstrate how the inventor understood the invention and whether the
inventor limited the scope of the invention during prosecution to avoid reading on prior art. Id.
“Under the doctrine of prosecution disclaimer, a patentee may limit the meaning of a claim term by
making a clear and unmistakable disavowal of scope during prosecution.” Purdue Pharma L.P. v.
Endo Pharmaceuticals Inc., 438 F.3d 1123, 1136 (Fed. Cir. 2006). “A patentee could do so, for
example, by clearly characterizing the invention in a way to try to overcome rejections based on
prior art.” Computer Docking Station Corp. v. Dell, Inc., 519 F.3d 1366, 1374 (Fed. Cir. 2008).
However, “[p]rosecution disclaimer does not apply to an ambiguous disavowal.” Id. at 1375.
Finally, if the ordinary and customary meaning of a claim term is not apparent from the
intrinsic evidence, courts are authorized to consult extrinsic evidence, which “consists of all
evidence external to the patent and prosecution history, including expert and inventor testimony,
dictionaries, and learned treatises.” Markman, 52 F.3d at 980.
The court’s findings of fact and conclusions of law made at the preliminary injunction stage
are not binding in subsequent proceedings, and claims may be provisionally construed for purposes
of deciding the motion. Outside the Box Innovations, LLC v. Travel Caddy, Inc., 695 F.3d 1285,
1302 (Fed. Cir. 2012). This is referred to as “rolling claim construction.” Id.

Application

Ormco contends that it is likely to prevail on its claim that WCT’s H4 brackets infringe
several claims of Ormco’s ‘896 Patent, specifically Claims 1, 2, 5, and 7. WCT argues that multiple
claim limitations in the ‘896 Patent are not met, focusing specifically on the “support surface”
limitation to illustrate this assertion.
Claim 1 of the ‘896 Patent reads:

OPINION AND ORDER

7

{KPR}

A self-ligating orthodontic bracket for coupling an archwire with a tooth,
comprising:
a bracket body configured to be mounted to the tooth, the bracket body
including a support surface, a ledge, and an archwire slot including a base surface
and opposing first and second slot surfaces extending from the base surface, the base
surface being interposed between the opposing first and second surfaces, the support
surface being acutely angled with respect to the base surface, and the ledge opposing
the support surface across the archwire slot and including a surface that is generally
parallel to the base surface; and
a movable member coupled with the bracket body and movable between an
opened position in which the archwire is insertable into the archwire slot and a
closed position in which the movable member retains the archwire in the archwire
slot,
wherein the movable member comprises a first portion and a second portion
extending at an acute angle from the first portion, the first portion engaging the
acutely angled support surface of the bracket body when the movable member is in
the closed position, the second portion being generally parallel to the base surface
and extending across the archwire slot from the first slot surface to the second slot
surface when the movable member is in the closed position.
(‘896 Patent 10:28-53 (emphasis added).) The parties dispute the proper construction of “support
surface.”
1.

Claim Language

As the Federal Circuit directs, the court must first consider the words of the claims
themselves. Ormco argues that the claim terms should be given their plain and ordinary meaning
and, as such, the phrase “support surface” should be construed as “a surface that supports.” In
support of its allegation of infringement, Ormco refers the court to the declaration of Dr. Roger W.
Toogood (“Dr. Toogood”). Dr. Toogood has forty years of experience in mechanical engineering
and has spent seven years focused on orthodontics. (Toogood Declaration (“Decl.”) ¶ 5.) Attached
to the declaration is a “claim chart” in support of Dr. Toogood’s “opinion that the H4 bracket
literally infringes claims 1, 2, 5, and 7 of the ‘896 patent.” Id. at ¶ 9.
Dr. Toogood’s claim chart is a simple chart with two columns. The first contains the

OPINION AND ORDER

8

{KPR}

language of the disputed claims and the second identifies the portions of the H4 bracket that meet
that particular limitation. This second column chiefly refers the court to six pages of “bracket specs”
that contain diagrams of the H4 bracket as well as promotional materials detailing the bracket
specifications. With respect to the claim language “support surface,” the chart refers exclusively
to “Sheet 6” which is a depiction of a portion of the H4 bracket in cross-section. This portion
includes the archwire slot and the body of the bracket. Dr. Toogood identifies a surface that,
functionally, provides the locking mechanism for the ligating slide. Although the surface appears
to be somewhat curved in the diagram, Dr. Toogood draws a line that is either flush with, or
potentially merely tangential to, this surface. Extending this line to the line formed by the plane of
the base of the archwire slot creates an acute angle. In the same diagram, Dr. Toogood identifies
another support surface – suggesting that there may be multiple surfaces rather than a singular
support surface – that is adjacent to the lip of the bracket that performs the locking function. This
surface makes contact with the front end of the ligating slide after it has locked into place in the
closed position.
WCT argues that the language of Claim 1 limits the meaning of “support surface” to surfaces
acutely angled with respect to the base surface of the archwire slot that also engage the slide, or
“movable member,” when it is in the closed position. WCT proposes the following construction:
“a surface on the bracket body which at least partially supports and guides the movable member
during movement between the open position and the closed position.” WCT first cites the claim
language, and argues that the claim language itself limits the meaning of “support surface” to a
surface that is acutely angled to the base surface, that lies across the archwire slot, and that engages
the first portion of the ligating slide, or movable member.

OPINION AND ORDER

9

{KPR}

Claim 1 describes a bracket with an archwire slot, this slot having a base surface and two
opposing surfaces such that the opposing surfaces extend out from the base surface. (‘869 Patent
10:31-34.) The bracket also contains a support surface that is “acutely angled with respect to the
base surface[.]” Id. at ‘869 Patent 10:35-37. The slide, or movable member, “engag[es] the acutely
angled support surface” when the bracket is closed. Id. at 10:45-49. Thus, the claim language alone
makes clear that the critical characteristic of the support surface is that it is acutely angled. The
claim language also refers to “the support surface” rather than “a support surface,” thus limiting the
device to a single support surface.
Ormco’s motion carries with it the burden to establish that is it likely to prevail on its
infringement claim. Its reliance on Dr. Toogood’s conclusory and unexplained chart is not sufficient
to meet the high burden necessary to justify a preliminary injunction. First, the surfaces identified
by Ormco as the support surfaces are both associated with the locking mechanism. As WCT argued
at hearing, the angled relationship between those surfaces and the base of the archwire slot is not
intrinsic to their functionality. Second, that Ormco identified multiple support surfaces runs
contrary to the claim language that refers to a singular surface, “the support surface.” Third, the
identified surfaces on the H4 bracket are not clearly defined and, in certain of the provided diagrams,
appear curved or arbitrarily highlighted. In light of Ormco’s burden at this stage to establish a
likelihood of success on its infringement claim, the court is unpersuaded that the claim language,
even when viewed in isolation, should be given the broad construction Ormco urges.
2.

The Specification

The court must next consider the construction of “support surface” in light of the
specification. “In reviewing the intrinsic record to construe the claims, we strive to capture the

OPINION AND ORDER

10

{KPR}

scope of the actual invention, rather than strictly limit the scope of claims to disclosed embodiments
or allow the claim language to become divorced from what the specification conveys is the
invention.” Retractable Technologies, 653 F.3d 1305. The specification may resolve ambiguities
present in the bare language of the claim. For example, in Retractable Technologies, the court had
to determine whether the term “body” in the claim language was limited to a single-piece body, or
could encompass a two-piece structure. The court evaluated both the claim language and the
specification and concluded that the claimed device was limited to a single-piece structure: “In this
case, while the claims leave open the possibility that the recited ‘body’ may encompass a syringe
body composed of more than one piece, the specifications tell us otherwise.” Id.
WCT cites Gentry Gallery, Inc. v. The Berkline Corp., 134 F.3d 1473 (Fed. Cir. 1998)
(“Gentry Gallery”) in support of its proposed construction. In Gentry Gallery, the court reviewed
a district court’s claim construction. The device in question was a seating unit comprised of two
reclining seats attached to and separated by a console, with the recliner controls located on the center
console. The alleged infringer, Berkline, argued that the claim language did not encompass devices
where the recliner controls were located somewhere other than the center console, because the patent
only described such units with controls on the center console. The patentee, Gentry, argued that the
unit with the controls on the center console was merely the preferred embodiment of the device, but
that the claim language supported devices with the controls located elsewhere.
Gentry, the patentee, cited Ethicon Endo-Surgery, Inc. v. United States Surgical Corp., 93
F.3d 1572 (Fed. Cir. 1993), for its proposition that an applicant is allowed claims beyond the scope
of its preferred embodiment, so long as they remain within the bounds of the prior art. The court
distinguished Ethicon, however, on the basis that, there, the “applicant ‘was free to draft claims

OPINION AND ORDER

11

{KPR}

broadly (within the limits imposed by the prior art) to exclude the lockout’s exact location as a
limitation of the claimed invention’ only because he ‘did not consider the precise location of the
lockout to be an element of his invention.’” Gentry Gallery, at 1479 (quoting Ethicon, 93 F.3d at
1582 n.7). In contrast, in the case before it, the inventor “considered the location of the recliner
controls on the console to be an essential element of his invention.” Gentry Gallery, at 1479. In a
similar vein, the court noted that “‘an applicant is entitled to claims as broad as the prior art and his
disclosure will allow.’” Id. at 1480 (quoting In re Rasmussen, 650 F.2d 1212, 1214 (C.C.P.A.1 1981)
(emphasis in original)).
The court agreed that the patent’s disclosure2 did not “support claims in which the location
of the recliner controls [was] other than on the console.” Gentry Gallery, 134 F.3d at 1479. It
acknowledged that “[i]t is a truism that a claim need not be limited to a preferred embodiment.
However, in a given case, the scope of the right to exclude may be limited by a narrow disclosure.”
Id. In its view, the disclosure of the patented device contemplated “only the most minor variation
in the location of the controls” and none outside of the console itself. Id. Additionally, the
disclosure was explicit that the sole purpose of the console was to act as the location of the recliner
controls. Id. As such, the court concluded that “locating the controls anywhere but on the console
is outside the stated purpose of the invention.” Id. The Gentry court concluded its discussion as
follows:

1

The United States Court of Customs and Patent Appeals, or “CCPA,” was a predecessor
court to the Federal Circuit Court of Appeals. Haggar Apparel Co. v. United States, 222 F.3d 1337,
1339 (Fed. Cir. 2000).

The disclosure refers to “everything revealed about an invention in the patent application,
including drawings, descriptions, specifications, references to prior art, and claims.” Black’s Law
Dictionary 532 (9th ed. 2009).
OPINION AND ORDER

12

{KPR}

In sum, the cases on which Gentry relies do not stand for the proposition that an
applicant can broaden his claims to the extent that they are effectively bounded only
by the prior art. Rather, they make clear that claims may be no broader than the
supporting disclosure, and therefore that a narrow disclosure will limit claim breadth.
Id. at 1480.
WCT also relies on Phillips in arguing that the specification must be consulted. In Phillips,
the Federal Circuit discussed the role of the claim language and the disclosure as a whole in the
process of claim construction. As an initial observation, the court wrote: “Importantly, the person
of ordinary skill in the art is deemed to read the claim term not only in the context of the particular
claim in which the disputed term appears, but in the context of the entire patent, including the
specification.” 415 F.3d at 1313. The Phillips court stressed the importance of the specification in
informing claim construction. In particular, “the specification ‘is always highly relevant to the claim
construction analysis. Usually, it is dispositive; it is the single best guide to the meaning of a
disputed term.’” Id. at 1315 (quoting Vitronics Corp. v. Conceptronic, Inc., 90 F.3d 1576, 1582
(Fed. Cir. 1996)). The specification assists the court in determining the “meaning” of the patent:
“Ultimately, the interpretation to be given a term can only be determined and
confirmed with a full understanding of what the inventors actually invented and
intended to envelop with the claim. The construction that stays true to the claim
language and most naturally aligns with the patent’s description of the invention will
be, in the end, the correct construction.”
Id. at 1316 (quoting Renishaw PLC v. Marposs Societa’ per Azioni, 158 F.3d 1243, 1250 (Fed. Cir.
1998)).
The Phillips court issued a caution as well, noting that although the specification is useful
in construing ambiguous claims, it should not be used to justify reading limitations from the
specification into the claim language. See 415 F.3d at 1323 (“Moreover, we recognize that the
distinction between using the specification to interpret the meaning of claim and imposing
OPINION AND ORDER

13

{KPR}

limitations from the specification into the claim can be a difficult one to apply in practice.”). This
practice was deemed particularly risky where the patent contains a single embodiment, and the
Federal Circuit has “expressly rejected the contention that if a patent describes only a single
embodiment, the claims of the patent must be construed as being limited to that embodiment.” Id.
In Phillips, the Federal Circuit urged district courts construing claim language to “keep in mind that
the purposes of the specification are to teach and enable those of skill in the art to make and use the
invention and to provide the best mode for doing so. . . . The manner in which the patentee uses a
term within the specification and claim usually will make the distinction apparent.” Id.3
In Ormco’s construction, a “support surface” may be any “surface that supports” the slide,
or movable member, in the closed position that is also acutely angled to the base surface of the
archwire slot. Ormco gives no guidance as to what constitutes support of the movable member, but
presumably this refers to a surface that is in contact with the movable member when the bracket is
in the closed position. Although Ormco acknowledges that the rest of the disclosure has relevance,
it urges the court to focus its evaluation almost exclusively on the claim language. However, beyond
arguing that a court may not import limitations from the specification into its construction of the
claim language, Ormco is unable to substantiate its position with relevant case law. Rather, the
cases cited by both parties are clear on this general point: the specification “is always highly
relevant to the claim construction analysis. Usually, it is dispositive; it is the single best guide to

3

As Ormco pointed out at hearing, the Phillips court ultimately sided with the patentee
although the patentee’s proposed construction was broader than the embodiments expressed in the
specification, all of which showed a particular element of the device at an acute angle to the primary
vertical orientation, whereas the invention claimed by the patentee included such element at right
angle to the primary vertical orientation. Thus, although the specification was consulted to reach
the appropriate construction of the element in question, the embodiments therein were not permitted
to limit the claim language beyond its plain meaning.

the meaning of a disputed term.” Vitronics, 90 F.3d at 1582.
WCT cites the specification in support of its construction of “support surface.” The
specification identifies several deficiencies of the existing self-ligating orthodontic brackets, one of
which is the tendency for the ligating slide to make contact with the gum tissue while in the open
position. As such, the bracket described in the ‘896 Patent was designed with the aim that the slide
would open and close on a “slide engagement track” that is angled such that the bracket opens away
from the gum tissue. The relationship between the translation plane for the ligating slide and the
base plane of the archwire slot, thus, gives meaning to the “acutely angled” limitation in the claim
language. WCT next cites an embodiment described in the specification which describes the support
surface as defining the slide engagement track, and cites the advantage of an angled relationship
between the slide engagement track and the base surface of the archwire slot.
After reviewing the patent in its entirety, including the claim language and the rest of the
disclosure, the court observes the following. In the “Abstract” section of the patent, the inventor
emphasized the angle of the movable member and how this enabled the bracket to avoid contact with
the gum tissue while in the open position. The first sentence describes a bracket with a slide that
moves along a translation plane, and the second sentence states only that the plane is “angled with
respect to the base plane.” (‘896 Patent at 1.) The third sentence describes the slide as running
parallel to the translation plane. In conclusion, the abstract states: “The translation plane is angled
with respect to the base plane so as to prevent the ligating slide from contacting the gingiva
surrounding the tooth when the ligating slide is moved to the open position.” (‘896 Patent at 1.)
In the “Background of the Invention” section of the patent, the inventor identifies three
problems that the invention solves, each of which are unique to placing brackets on molars. These

OPINION AND ORDER

15

{KPR}

difficulties arise because of the position and location of the molars in the mouth and their
comparatively smaller size. (‘896 Patent at 2.) This section of the patent in no way addresses or
even alludes to a mechanism for locking or securing the slide when in the closed position, for molars
or any other teeth.
The “Summary of the Invention” section of the patent repeatedly emphasizes the bracket’s
angled slide which avoids the gum tissue while in the open position. It describes several aspects of
the invention, the first being the translation plane acutely angled to the base plane “to prevent the
ligating slide from contacting the gingiva surrounding the tooth when the ligating slide is moved to
the opened position.” (‘896 Patent 2:42-25.) The summary next describes the relationship between
the first and second portions of the slide which are designed to hold the archwire securely in the
archwire slot by producing a “close fit.” (‘896 Patent 2:45-52.) The bracket surface is also designed
to avoid occlusion with teeth on the opposite jaw and includes a “planar surface” that may be
gripped with an orthodontic tool for purposes of applying the bracket to the tooth. (‘896 Patent
2:53-63.) The bracket is also designed to prevent the slide from disengaging from the bracket body.
(‘896 Patent 2:64-3:10.)
Importantly, the phrase “support surface” is used exclusively to reference the portion of the
bracket upon which the ligating slide moves and rests, i.e., the translation plane. The phrase
“support surface” is not used in conjunction with any other part of the bracket and, thus, is not
contemplated as a reference to a portion of the locking mechanism on the leading end of the slide.
For example, the specification refers to the translation plane and its angled relationship to the base
plane, in order to avoid contact between the ligating slide and the gum tissue. With respect to the
angle used in a preferred embodiment, the specification reads: “To prevent the ligating slide from

contacting the gingiva, the base plane and translation plane have an angle . . . preferably
approximately 20 degrees. The invention, however, is not so limited and, as recognized by those
of ordinary skill in the art, other angles suitable for a particular application are possible.” (‘896
Patent 5:65-6:23.)
The specification also describes the locking mechanism used to secure the ligating slide in
the closed position in the bracket. It reads: “A resilient engagement member operates to secure the
ligating slide in the closed position. The resilient engagement member is generally L-shaped and
includes a lingually-extending prong that is received in a recess formed in support surface.” (‘896
Patent 6:41-45.) The reference number identifies the support surface as the same surface described
throughout the patent, namely the surface upon which the ligating slide moves and rests. This
language reinforces the distinction between the support surface of the bracket, which is angled to
prevent an open slide from contacting the gum tissue, and the portion of the slide that locks the slide
in the closed position. The recess in which the locking mechanism engages is a recess in the support
surface, and not the support surface itself. This directly refutes Ormco’s argument that “support
surface” refers to any bracket surface that “supports” because the recess in which the locking prong
rests is something different than the support surface, i.e., the surface upon which the ligating slide
moves and rests.
The mechanism regulating the movement of the slide is also addressed in the specification,
and this mechanism is made up of a projecting and a receiving portion such that a “retaining pin”
is inserted into a “slot.” (‘896 Patent 7:39-56.) “The retaining pin/slot configuration prevents
accidental or unintentional detachment of the ligating slide from the bracket body during use when
the ligating slide is positioned in the opened position. It should be realized that the retaining pin/slot

17

{KPR}

configuration does not lock the ligating slide in any position . . . but regulates” its movement. (‘896
Patent 7:56-63.) Again, no reference is made to the “support surface” or an acute angle.
The patent, viewed in the context of the specification, describes a device with several aspects
and potential embodiments. It does not, however, describe a bracket that is merely characterized
by a surface on the bracket, in contact with the ligating slide, that is at an acute angle to the base of
the archwire slot. It similarly does not evidence an intent to encompass a bracket where this surface
acts to secure the ligating slide in the closed position. The invention in question is directed primarily
at the problem of contact between the ligating slide and the patient’s gum tissue. Ormco’s proposed
construction does not capture the meaning of the patent and is both internally inconsistent with the
claim language and contrary to the patent’s disclosure as a whole. With respect to “support surface,”
then, the claim language and the specification do not support the narrow construction urged by
Ormco.
The court hereby adopts, at this stage, the construction proposed by WCT. Under this
construction, the H4 bracket clearly does not meet every limitation of Claim 1 of the ‘896 Patent,
most notably the requirement that the support surface be acutely angled to the base of the archwire
slot. The remaining claims asserted by Ormco, Claims 2, 5, and 7, are dependent on Claim 1 and,
therefore, Ormco has similarly failed to establish a likelihood of success on the merits of its
allegation of infringement of those claims. See Wahpeton Canvas Co. v. Frontier, Inc., 870 F.2d
1546, 1552 (Fed. Cir. 1989) (“One who does not infringe an independent claim cannot infringe a
claim dependent on (and thus containing all the limitations of) that claim.” (citation omitted)).
Ormco cannot establish a likelihood of the success on the merits of its infringement claim, and its
motion is denied.

Prosecution History

WCT also refers the court to the prosecution of the ‘896 Patent, arguing that it adds further
credence to its proposed construction of “support surface.” According to WCT, in its “Amendment
After Final Rejection,” Ormco submitted an additional claim which is now Claim 6 of the issued
‘896 Patent. (Smith-Hill Decl., Ex. B.) The amendment was for the purpose of clarifying the
meaning of “planar projection” and reads: “The self-ligating orthodontic bracket of claim 1, wherein
the support surface intersects one of the opposing first and second slot surfaces to define an edge
of the archwire slot and the support surface defines a translation plane that intersects the other of the
opposing first and second slot surfaces.” (Id. at 9.) In the “Remarks” section of the amendment,
Ormco stated that the “support surface and translation plane are disclosed in at least paragraph
[0031] and depicted in Fig. 3.” (Id. at 12.)
According to WCT, paragraph 31 refers to this portion of the issued patent:
In another advantageous aspect of the invention, the slide engagement track
and the archwire slot generally have a non-orthogonal relationship. In particular, the
base surface of the archwire generally defines a base plane and the slide engagement
track generally defines a translation plane along which the ligating slide moves
between the opened and closed positions. It should be recognized that base surface
and slide engagement track need not be precisely planar but be configured such that
base plane and translation plane may be generally defined. The base plane and
translation plane are acutely angled with respect to each other by angle A, as shown
in Fig. 3. In this way, as the ligating slide is moved from the closed position to the
opened position along slide engagement track and parallel to translation plane, the
ligating slide moves generally in the labial-gingival direction so that the edge of the
ligating slide does not make contact with the gingiva adjacent orthodontic bracket
when mounted to molar teeth.
(‘896 Patent 5:65-6:23.) WCT also notes that the sentences immediately prior to this paragraph refer
to the support surface as defining the slide engagement track. As such, WCT argues that the
inventor’s use of “support surface” in the claim language is consistent with its use in the

OPINION AND ORDER

19

{KPR}

specification, “as the surface which defines both the translation plane and the slide engagement
track.” (Response at 14.)
Ormco responds that this argument is misplaced because it concerns the language of Claim
6, rather than the disputed language in Claim 1, and that the phrase “support surface” is never
referenced in the prosecution history. At hearing, however, Ormco argued that the language of
Claim 6 and principles of claim differentiation lend support to its construction of “support surface”
because WCT’s construction would render the language of Claim 6 superfluous. In its visual
presentation at hearing, it cited the Phillips court: “[T]he presence of a dependent claim that adds
a particular limitation gives rise to a presumption that the limitation in question is not present in the
independent claim.” 415 F.3d at 1315 (citing Liebel-Flarsheim, 358 F.3d at 910). WCT was unable
present argument to refute Ormco’s argument, as the argument was presented for the first time at
the hearing on this motion.
As a preliminary note, a presumption created under the doctrine of claim differentiation “will
be overcome by a contrary construction dictated by the written description or prosecution history.”
Seachange Int’l, Inc. v. C-COR, Inc., 413 F.3d 1361, 1369 (Fed. Cir. 2005)). Furthermore, the court
does not agree that WCT’s construction of support surface would render the language of Claim 6
superfluous. Claim 6 reads: “The self-ligating orthodontic bracket of claim 1, wherein the support
surface intersects one of the opposing first and second slot surfaces to define an edge of the archwire
slot and the support surface defines a translation plane that intersects the other of the opposing first
and second slot surfaces.” (‘896 Patent 11:1-5.) This claim describes a specific configuration of
the archwire slot, the support surface, and the translation plane as defined by the support surface.
Claim 6 provides that one edge of the archwire slot is defined by the support surface, which extends

{KPR}

along the translation plane to intersect with the opposing edge of the archwire slot. Ormco’s
conclusory representations that Claim 6 describes the preferred embodiment or is otherwise
superfluous are insufficient to disturb the court’s construction of “support surface.” With respect
to WCT’s contention that the prosecution history supports its proposed construction, the court
declines to rule on this issue in light of its adoption of this construction based on the claim language
and the specification.
II.

Validity
Upon the court’s adoption of WCT’s construction of “support surface,” the issue of validity

becomes moot. WCT has implicitly conceded that the ‘896 Patent remains valid under its
construction. See Response (#47) at 20 (citing its own construction of “support surface,” WCT
writes “[s]o long as ‘support surface’ is construed to refer to that surface, the claim is adequately
enabled and described by the specification.”); see also Response (#47) at 22 (“Note that WCT does
not argue that the following references enable the ‘896 patent as properly construed in the context
of the teaching of the patent’s specification.” (emphasis in original)). It follows that, having adopted
WCT’s construction, the invalidity issues are no longer in dispute on this motion.
III.

Other Factors
As stated above, the court need not analyze the remaining factors where the patentee fails

to show a likelihood of success on the merits of its infringement claim. This approach is routinely
followed by district courts, and this court sees no reason to further weigh the impacts of lawful, noninfringing conduct. See Maxwell Techs., Inc. v. Nesscap, Inc., 508 F. Supp. 2d 837, 849 (“Because
the Court has found that Plaintiff has not met its burden of showing likelihood of success on the
merits regarding infringement by the accused products, it need not address any other preliminary

OPINION AND ORDER

21

{KPR}

injunction factor.” (citing Reebok Int’l, 32 F.3d at 1556)); see MMJK, Inc. v. Ultimate Blackjack
Tour LLC, 513 F. Supp. 2d 1150, 1153 (N.D. Cal. 2007) (“In other words, if defendant ‘raises a
substantial question concerning either infringement or validity, i.e., asserts an infringement or
invalidity defense that the [plaintiff] cannot prove “lacks substantial merit,” the preliminary
injunction should not issue.’” (quoting Amazon.com, Inc., 239 F.3d at 1350-1351)).
Conclusion
Ormco cannot establish a likelihood of success on the merits of its infringement claim and,
therefore, its Motion for Preliminary Injunction (#36) is DENIED.
IT IS SO ORDERED.
