Judge Edmond E. Chang
MEMORANDUM OPINION AND ORDER
Kolcraft Enterprises, Inc. manufactures and sells a variety of baby products,
including play gyms (comprised of arches from which toys dangle) and play yards
(basically, an enclosed play pen). Kolcraft owns patent number 7,376,993 (the ’993
patent), which covers a method for using a play gym with a mat, a bassinet (a cradle
where a baby sleeps), a play yard, or any combination of the three products. Kolcraft
alleges that Chicco USA, Inc. (which does business as Artsana USA, Inc.) has
infringed on the patent.1 The parties have briefed the construction of the patent’s
disputed claims, and the Court held an in-court claim-construction hearing where
the parties presented argument. The Court’s construction of those claim terms is set
forth below.
1The
1338.
Court has subject matter jurisdiction over this case under 28 U.S.C. §§ 1331,
I. Background
A. Procedural History
This case, which has a long-winded history, involves two competitors in the
baby-products industry. R. 1, Compl. ¶¶ 2, 5.2 Kolcraft owns the ’993 patent, which
was issued in May 2008 and covers “play gyms and methods of operating the same.”
R. 147-1, Joint App’x at JA-000001, ’993 Patent. The ’993 patent originally consisted
of 31 claims, including apparatus claims 1-27 and method claims 28-31. Id. In June
2009, Kolcraft sued Artsana for making products that allegedly infringed the ’993
patent, including “at least” apparatus claims 1-12 and 18-27. Compl. ¶ 9.3 (Because
the defense refers to Chicco as Artsana, the Court will do so as well.) Upon learning
of the suit, Artsana filed a Request for Reexamination with the Patent and
Trademark Office, raising challenges to all 31 claims of the ’993 patent. R. 46. In
December 2009, this case was put on hold pending the patent reexamination. R. 57,
12/10/09 Minute Entry.
The PTO proceedings continued throughout 2010 and 2011, R. 77, 79, 81, 83,
and even proceeded beyond then. In February 2010, the PTO rejected claims 1-12
and 18-27, which were the claims that Kolcraft asserted in its Complaint. R. 87,
Def.’s Resp. to Pl.’s Mot. to Lift Stay ¶ 7. At the PTO, Kolcraft amended some claims
and added claims 32-68. Id. ¶ 8. In December 2010, the PTO confirmed the
patentability of claims 28-31 and deemed some of the new and amended claims

patentable, while rejecting others. Id. ¶ 17. After additional challenges by the
parties, the PTO issued another decision in November 2011 again confirming claims
28-31, and deeming claims 1-27, 32, 34, 37-50, 52-60, and 63-67 patentable. Id. ¶ 22;
R. 84-1, Pl.’s Exh. 1, 11/2/11 PTO Action Closing Prosecution. In March 2012, even
though the PTO had not yet issued a reexamination certificate or an appeal notice
(meaning that the PTO proceedings were not officially complete), the Court lifted
the stay because it had the benefit of the PTO’s reexamination, and because waiting
until the end of the appeals process “will likely require a years-long additional
delay.” R. 96, 3/7/12 Minute Entry. With that, the case proceeded and discovery
began. Id.
In April 2012, Kolcraft issued its initial infringement contentions, alleging
that in addition to the claims originally asserted in its Complaint, Artsana had also
infringed claims 28-31, 43-49, and 68 of the ’993 patent. R. 112-2, Pl.’s Exh. B,
4/3/12 Infringement Contentions ¶ a. (Remember that Kolcraft originally asserted
infringement of “at least” claims 1-12 and 18-27. Compl. ¶ 9.) Artsana then moved
to dismiss the action for lack of subject matter jurisdiction, arguing that claims 4349 and 68 were not yet part of the ’993 patent because the PTO had not yet issued a
reexamination certificate that officially incorporated these claims into the patent. R.
127, Def.’s Mot. to Dismiss Br. The Court denied Artsana’s motion, but clarified that
only claims 28-31, which were originally a part of the ’993 patent and were later
confirmed by the PTO, could be litigated at this time. R. 142, 5/31/12 Minute Entry.
3
In the meantime, Artsana had appealed the PTO’s reexamination and was awaiting
a decision from the Board of Patent Appeals.4 R. 144, 9/19/12 Minute Entry.
The parties then began the claim-construction process for claims 28-31. After
the parties briefed the issue, the Court held a Markman hearing on February 19,
2013, R. 163, and accepted additional post-hearing submissions, R. 166-67. In
December 2015, the Patent Trial and Appeal Board issued a new decision on several
claims, and affirmed the patentability of claims 28-31. R. 206, Pl.’s Notice of
Decision; R. 206-1, Pl.’s Exh. 1, 12/7/15 PTAB Decision. Artsana then filed a request
for rehearing of this PTAB decision. R. 208. Recently, in August 2016, the PTAB
“considered the Original Decision [from December 2015] in light of the Request for
Rehearing, and [] elaborated on certain aspects of it,” but “decline[d] to modify the
Original Decision in any respect.” R. 214-1, 8/8/16 PTAB Decision. So the PTAB
again confirmed the patentability of claims 28-31 of the ’993 patent. Id.
B. The ’993 Patent
The ’993 patent involves play gyms, play yards, bassinets, and mats. See
generally ’993 Patent. A play gym is a popular baby product that has “flexible
arches for suspending objects such as toys.” ’993 Patent col. 1 ll. 53-57. The arches
cross over each other and form a dome-like shape. Id. When the play gym is placed
over a baby, “the suspended objects tend to bounce and move in response to
vibrations … caused by the child batting his/her hands and/or feet at the objects.”
Id. col. 1 ll. 57-62. (A drawing of a play gym appears on the next page.)
4The
Board of Patent Appeals was the precursor to the Patent Trial and Appeal
Board, the latter of which was formed as part of the America Invents Act of 2012. LeahySmith America Invents Act, Pub. L. No. 112-29, § 7(a)(1), 125 Stat. 284 (2011).
4
The ’993 patent explains that a play gym can be used in combination with
other baby products, such as a play yard, bassinet, or mat. A play yard is an
enclosed playpen that “typically include[s] a frame, a fabric supported by the frame,
and removable floor board or mat.” Id. col. 1 ll. 18-20. A portable bassinet, which is
a cradle where an infant sleeps, can also be placed inside the top of the play yard.
Id. col. 1 ll. 28-39. The bassinet typically has the same length and width as the play
yard, but it is shallower than the yard, so there is empty space between the bottom
of the bassinet and the bottom of the play yard. Id. The floor mat of the play yard
can also be used inside the bassinet, or it can be removed and used separately from
the play yard or the bassinet. Id. col. 1 ll. 46-51.
The play gym can be used any number of ways with the play yard, bassinet,
floor mat, or with a combination of the three products. Id. col. 1 ll. 46-62. The
figures below show some of the combinations:
5
’993 Patent at Sheet 1-2. Figure 1, for example, shows the play gym placed over a
bassinet, while the bassinet is sitting inside the play yard. Id. col. 1 ll. 66-67 (“FIG.
1 is a perspective view of an example play yard, an example bassinet, and an
example play gym.”). In this example, the floor mat serves as the base of the
bassinet. (The bottom of the bassinet is labeled 16,5 which is the number
representing the floor mat.) Although not shown in Figure 1, the play gym can also
be used with the play yard (whose base is comprised of the mat), but without the
bassinet. E.g., col. 1 ll. 44-46 (explaining that the play gym can be used “above any
or all of the bassinet 12, the play yard 14, and the mat 16” (emphasis added)); id.
col. 7 ll. 1-2 (“In operation, a user wishing to use the play gym 10 may first erect a
bassinet 12 and/or a play yard 14.” (emphasis added)). Similarly, although not
shown in the figures, the play gym can also be used with only the bassinet (whose
base is comprised of the mat), but without the play yard. Id. Figure 2 shows a
different combination—the play gym is used with only the floor mat, and is
completely outside of the play yard/bassinet setup. Id. col. 2 ll. 1-3 (“FIG. 2 is a
perspective view of the example play gym of FIG. 1 when removed from the play
yard and bassinet, and coupled to a floor mat of the play yard and bassinet.”).
When the play gym is in use, it is secured in an arched position to the play
yard, bassinet, or the mat with some type of “connector.” Id. col. 5 ll. 39-43 (noting
“connectors” of some kind on the bassinet or the play yard). The force of the
connection keeps the play gym’s legs bent into the arched position shown above in
5The
numbers match the item described in the specification with the corresponding
item in the drawings.
6
Figures 1 and 2; otherwise, without some force applied, the legs will spring back
into a straight position shown here in Figure 3:
See id. col. 3 ll. 61-65 (“[T]he legs 22 of the play gym 12 are flexible such that they
can be bent into the arched position shown in FIGS. 1 and 2, but will spring back to
the generally planar position shown in FIG. 3 when released from the mat 16, the
bassinet 12, and/or the play yard 14.”); id. col. 5 ll. 15-20 (“As shown in FIG. 1 … the
legs must be bent into an accurate shape thereby causing the play gym to form a
pair of arches crossing one another at the hub 20 … .”); id. col. 6 ll. 56-58 (“When
the legs 22 are released, they will attempt to move from their bent position toward a
straight position … .”). To secure the play gym in this arched position, a user can
attach it to the bassinet or the play yard “in any number of ways.” Id. col. 5 ll. 4-9.
For example, the play gym’s legs may be inserted into fabric pockets in the corners
of the bassinet or the play yard; the legs try to push out but the pockets keep them
in place. Id. col. 5 ll. 26-38. In other words, “[t]hese forces act to … bias the free
ends of the legs 22 into tight engagement with the sides of the pockets 50 (and,
thus, with the frame of the bassinet 12 and/or play yard 14) to thereby securely hold
7
the play gym 10 above the bassinet 12 and/or the play yard 14.” Id. col. 5 ll. 32-38.
But if the bassinet or play yard lacks pockets or other connectors, the play gym can
instead be directly “coupled to the corners of a rectangular mat via snaps or the
like.” Id. col. 1 ll. 52-56; see also id. col. 5 ll. 43-47 (“Alternatively, no connectors 50
may be located on the bassinet 12 and/or the play yard 16, and the play gym 10 can
instead be coupled to the bassinet 12 and/or the play yard 14 via direct connection
to the mat 16.”). Another possibility is that the play gym can be wedged into the
play yard or bassinet and held there by friction alone, such as by the resistance
from the walls of the bassinet or play yard. Id. col. 5 ll. 26-38 (explaining that the
play gym’s legs will be “bias[ed] … into tight engagement … with the frame of the
bassinet 12 and/or the play yard 14[] to thereby securely hold the play gym 10 above
the bassinet 12 and/or the play yard 14”).
Finally, when the child is done using the play gym, the caretaker can store
the gym by folding the legs into a parallel position. The play gym’s legs are attached
directly to each other or to a central hub; for example, the legs may be “pivotably
coupled to a hub 20 such that they can be pivoted between a stored position wherein
the legs 22 are positioned generally parallel to each other as shown in FIG. 4, and
an extended position herein the legs 22 extend generally radially outward from the
hub 20 as shown in FIG 3.” Id. col. 4 ll. 5-10. Below, Figure 3 shows the legs in an
extended position when they are disconnected from a play yard, bassinet, or mat.
And Figure 4 shows the legs in a closed position for storage.
8
C. Claims 28-31
The parties dispute the meaning of Claims 28-31, all of which are process
claims. As explained above, these are the only finalized claims that can be litigated
at this juncture, because the PTO has not yet issued a reexamination certificate
finalizing the other relevant claims. The Court recites Claims 28-31 below,
emphasizing the disputed terms in italics. First, Claim 28 describes
A method comprising:
securing a play gym at least partially above at least one of a bassinet
and a play yard;
removing the play gym from the at least one of the bassinet and the
play yard;
securing the play gym to a mat apart from the play gym and the
bassinet;
removing the play gym from the mat; and
collapsing the play gym, wherein collapsing the play gym comprises:
pulling a leg of the play gym in a direction away from a hub; and
pivoting the leg into a stored position.
9
’993 Patent col. 10 ll. 6-18. The remaining claims 29-31 elaborate on the process for
collapsing and storing the play gym:
29. A method as defined in claim 28 wherein pulling the 20 leg of the
play gym comprises pulling the leg of the play gym against a spring
force.
30. A method as defined in claim 28 further comprising moving the leg
of the play gym toward the hub to secure the leg in the stored position.
31. A method as defined in claim 30 wherein moving the leg toward the
hub comprises moving the leg toward the hub under the influence of a
spring force.
Id. col. 10 ll. 19-27.
II. Legal Standard
To construe claim language in a patent, courts “first look to, and primarily
rely on[] the intrinsic evidence,” which “includ[es] the claims themselves, the
specification, and the prosecution history of the patent.” Sunovion Pharms., Inc. v.
Teva Pharms. USA, Inc., 731 F.3d 1271, 1276 (Fed. Cir. 2013) (citations omitted).
When analyzing the intrinsic evidence, the Court begins with the language of the
claims themselves, applying a “heavy presumption that claim terms take on their
ordinary meaning as viewed by one of ordinary skill in the art.” Altiris, Inc. v.
Symantec Corp., 318 F.3d 1363, 1369 (Fed. Cir. 2003) (citations and quotations
omitted). A claim term takes on its ordinary meaning unless the patentee
demonstrates an intent to deviate from that meaning, such as by “act[ing] as his
own lexicographer,” or by “disavow[ing] the full scope of a claim term either in the
10
specification or during prosecution.” Starhome GmbH v. AT&T Mobility LLC, 743
F.3d 849, 856 (Fed. Cir. 2014) (citations and quotations omitted).
“In most situations, an analysis of the intrinsic evidence alone will resolve
any ambiguity in a disputed claim term.” Vitronics Corp. v. Conceptronic, Inc., 90
F.3d 1576, 1583 (Fed. Cir. 1996); see also Sunovion Pharms., 731 F.3d at 1276
(noting that the intrinsic evidence is “usually dispositive” (citations omitted)). In
such cases, “it is improper to rely on extrinsic evidence,” which includes dictionary
definitions, expert testimony, inventor testimony, and other “evidence that is
external to the patent and file history.” Vitronics, 90 F.3d at 1583-84 (citations
omitted). Extrinsic evidence, however, may be considered “if needed to assist in
determining the meaning or scope of technical terms in the claims.” Pall Corp. v.
Micron Separations, Inc., 66 F.3d 1211, 1216 (Fed. Cir. 1995) (citation omitted). In
other words, it may be consulted to ensure that a court’s construction of a claim “is
not inconsistent with clearly expressed, plainly apposite and widely held
understandings in the pertinent technical field.” Plant Genetic Sys., N.V. v. DeKalb
Genetics Corp., 315 F.3d 1335, 1346 (Fed. Cir. 2003) (citation and quotations
omitted). Extrinsic evidence in general, however, is considered “less reliable than
the patent and its prosecution history in determining how to read claim terms,”
SkinMedica, Inc. v. Histogen Inc., 727 F.3d 1187, 1195 (Fed. Cir. 2013) (citation and
quotations omitted), and “may not be used to vary or contradict the claim language”
and specification, Vitronics, 90 F.3d at 1584 (citation omitted).

III. Analysis
A. Securing a play gym at least partially above at least one of a bassinet
and a play yard
Artsana argues that the first clause in Claim 28—“securing a play gym at
least partially above at least one of a bassinet and a play yard”—is indefinite and
overly broad because it does not explain how, and to what, the play gym is secured.
R. 146, Def.’s Br. at 10-13. In Artsana’s view, the claim language potentially covers
hanging the play gym from a ceiling or cantilevering it from a fixture other than the
play yard, bassinet, or mat; in both cases, the play gym could technically be
“partially above” the bassinet and/or the play yard. Id.6
In order to be sufficiently definite, a patent must set forth “one or more
claims particularly pointing out and distinctly claiming the subject matter which
the applicant regards as his invention.” 35 U.S.C. § 112(b). The purpose of this
requirement is to ensure that the public is on notice as to what is covered by the
patent, which in turn enables competitors to avoid infringement. Halliburton
Energy Servs. v. M-I LLC, 514 F.3d 1244, 1249 (Fed. Cir. 2008) (“[T]he patent
statute requires that the scope of the claims be sufficiently definite to inform the
6The
parties disagree about the level of experience of a person of ordinary skill in the
art. Artsana defines the ordinary artisan as “someone with two (2) years of formal
education in the mechanical arts or two (2) years of industry experience in the baby gear
field.” Def.’s Br. at 8. But Kolcraft defines the individual as “someone with a B.S. degree in
mechanical engineering or industrial design, and two to three years’ experience in the
juvenile products industry.” R. 150, Pl.’s Resp. at 9 n.2.
The Court does not choose one definition over another, however, because the parties
have not explained how they arrived at these particular definitions. Nor do the parties
argue that any differences in the ordinary artisan’s skill level would impact the claimconstruction outcome. So whether the Court adopted Kolcraft or Artsana’s definition, the
analysis would remain the same.
12
public of the bounds of the protected invention, i.e., what subject matter is covered
by the exclusive rights of the patent.”) Because a claim’s definiteness affects a
court’s ability to construe a claim, it sometimes makes sense to address an
indefiniteness challenge, which is a legal question, during claim construction. E.g.,
3M Innovative Props. Co. v. Tredegar Corp., 725 F.3d 1315, 1333 (Fed. Cir. 2013)
(“In order to be indefinite, reasonable efforts at claim construction must result in a
definition that does not provide sufficient particularity or clarity to inform a skilled
artisan of the bounds of the claim.” (citation omitted)); Praxair, Inc. v. ATMI, Inc.,
543 F.3d 1306, 1319 (Fed. Cir. 2008) (“Indefiniteness is a matter of claim
construction, and the same principles that generally govern claim construction are
applicable to determining whether allegedly indefinite claim language is subject to
construction.” (citation omitted)). Consistent with the statutory presumption of
patent validity, the patent’s challenger must show indefiniteness by clear and
convincing evidence. Wellman, Inc. v. Eastman Chem. Co., 642 F.3d 1355, 1366
(Fed. Cir. 2011) (citations omitted). Specifically, the challenger must show that the
patent’s claims fail, when “viewed in light of the specification and prosecution
history, [to] inform those skilled in the art about the scope of the invention with
reasonable certainty.” Nautilus, Inc. v. Biosig Instruments, Inc., 134 S. Ct. 2120,
2129 (2014).
Here, the first clause of Claim 28 is sufficiently definite, because the claim
and the specification make it reasonably certain that the play gym must be secured
to the play yard, bassinet, or the mat (taking care of Artsana’s question, to what is
13
the play gym secured?), and the term “secured” also has a reasonably certain
meaning (taking care of Artsana’s question, how is the play gym secured?), as
explained below.
The specification shows that one way of practicing the claim is by directly
attaching the play gym to the play yard, bassinet, or floor mat by using “connectors”
of some kind. ’993 Patent col. 7 ll. 5-9 (“The user may then secure the play gym 10
at least partially above one or both of the bassinet 12 and the play yard 14 by, for
example, inserting the feet 68 of the legs 22 into the connectors 50 of the bassinet
12 and/or play yard 14 or into the connectors of the mat 16.”). These connectors can
be “implemented in any number of ways,” including “fabric pockets 50 which are
sewn or otherwise fastened adjacent the corners of the bassinet 12 and/or the play
yard 14,” id. col. 5 ll. 7-12, or by “snaps” on the mat, id. col. 1 ll. 53-56. The presence
of some sort of connection is also supported by the specification’s repeated use of the
word “coupled.” See id. col. 1 ll. 53-56 (play gym “is coupled to the corners of a
rectangular mat via snaps or the like”); id. col. 2 ll. 2-3 (play gym is “coupled to a
floor mat of the play yard and bassinet”); id. col. 5 ll. 45-47 (“[T]he play gym 10 can
instead be coupled to the bassinet 12 and/or the play yard 14 via direct connection
to the mat 16.”). The term “coupled” requires that the play gym be directly
connected to the bassinet, play yard, or mat, and not suspended in mid-air or
cantilevered above them. Similarly, Figures 1 and 2, see supra Section I.B, also
suggest that Claim 28 does not cover a play gym that is suspended over and not in
contact with the mat, bassinet, or play yard. See Teleflex, Inc. v. Ficosa N. Am.
14
Corp., 299 F.3d 1313, 1324 (Fed. Cir. 2002) (“The words used in the claims are
interpreted in light of the intrinsic evidence of record, including the written
description, the drawings, and the prosecution history, if in evidence.” (citations
omitted)).
The only other way that the specification demonstrates the securing of the
play gym likewise requires that the play gym be in direct contact with the bassinet,
play yard, or mat. Specifically, the play gym can be wedged into the play yard or
bassinet and held there by friction alone, such as by the resistance from the walls of
the bassinet or play yard. Id. col. 5 ll. 26-38 (explaining that the play gym’s legs will
be “bias[ed] … into tight engagement … with the frame of the bassinet 12 and/or
the play yard 14[] to thereby securely hold the play gym 10 above the bassinet 12
and/or the play yard 14”). In this scenario, the play gym’s legs are held in an arched
position by the sides of the play yard or the play mat, and will spring back into a
straight position when pulled out of the play yard/bassinet. ’993 Patent col. 5 ll. 2632 (“[A]fter being bent, the legs 22 will seek to return to their original, generally
straight condition … . As a result, when the legs 22 are bent into the arched
position … , each of the ends of the legs 22 will apply a force away from the center of
the bassinet 12 and/or the play yard 14 seeking to return the legs 22 into the
straight position.”); id. col. 6 ll. 56-58 (“When the legs 22 are released, they will
attempt to move from their bent position toward a straight position … .”). Even
though the play gym is not attached to another object in this friction-fit option, the
play gym is still in direct contact with the mat, play yard, or bassinet—otherwise,
15
its legs return to a straight position, rendering the play gym unusable. See id. So
under this construction too, this claim does not cover a cantilevered, suspended, or
otherwise hovering play gym.7
In sum, Claim 28’s plain language and specification both show that “securing
a play gym” means that the play gym must be connected to, attached to, or
otherwise in direct contact with the play yard, bassinet, or mat, such that the play
gym’s legs are arched in a fixed position.8
7Kolcraft’s
position at the Markman hearing was consistent with this claim
construction. Kolcraft agreed that the play gym has to be connected in some fashion to the
play yard, bassinet, or play mat, and that the claim does not cover a cantilevered or
otherwise suspended device. R. 176, 2/19/13 Hr’g Tr. 16:8-12 (“Well, the specification talks
about securing [the play gym] by connectors to the play yard, bassinet, or the mat. You
could also have it where it is connected, where it is like a friction fit, and it just kind of sits
in there with the legs and through friction is maintained.”); id. 16:20-24 (“[I]f the play gym
is secured to the wall and is cantilevered out or from the ceiling, it is not going to infringe
that claim … .”); id. 17:17-19 (“I would agree, the cantilever design would not be covered …
.”).
8Artsana also argues that the phrase “securing a play gym at least partially above at
least one of a bassinet and a play yard” is invalid for lack of written description under 35
U.S.C. § 112(a). Because the ’993 patent’s specification does not say that the play gym can
be hung from the ceiling or cantilevered from another fixture, so Artsana’s argument goes,
the first clause of Claim 28—which does not explicitly require the play gym to be connected
to the play yard, bassinet, or mat—is impermissibly broader than the specification. See
Def.’s Br. at 13 (“Because claim 28 omits an essential element for ‘securing’ the play gym, it
is broader than the invention described in the ‘993 Patent and the ‘993 Patent lacks the
required written description pursuant to 35 U.S.C. § 112, first paragraph.”); R. 158, Def.’s
Reply at 3 (arguing that the “claim overreaches the scope of the … specification”).
But this written-description argument is premised on Artsana’s claim-construction
argument, which the Court has rejected: the claim does not cover a play gym that is hung
from the ceiling or cantilevered from a fixture other than the play yard, bassinet, or mat.
See supra. As described above, the specification and the claim language are consistent in
requiring some sort of physical connection or direct contact. Id. Thus, the claim meets the
written-description element because the patent “clearly allow[s] persons of ordinary skill in
the art to recognize that [the inventor] invented what is claimed.” Ariad Pharm., Inc. v. Eli
Lilly & Co., 598 F.3d 1336, 1351 (Fed. Cir. 2010) (citations and quotations omitted). (It is
worth noting that the rejection of this written-description argument does not preclude
Artsana from making some other written-description invalidity argument at a future stage
of the litigation.)

B. Securing the play gym to a mat apart from the play gym and the
bassinet
Next, Artsana argues that the third clause of Claim 28, “securing the play
gym to a mat apart from the play gym and the bassinet,” is nonsensical and renders
the whole claim indefinite. That is, “[i]f the play gym is secured to a mat, then by
definition, the mat cannot be ‘apart’ from the play gym.” Def.’s Br. at 13. Kolcraft
argues that there is an obvious typographical error, and that the claim should say:
“securing the play gym to a mat apart from the play gym yard and the bassinet.” R.
150, Pl.’s Resp. at 11-14.
The Court agrees with Kolcraft that this clause includes a clear typographical
error that, when fixed, renders the term definite. A court can correct a
typographical error in a patent “if (1) the correction is not subject to reasonable
debate based on consideration of the claim language and the specification and (2)
the prosecution history does not suggest a different interpretation of the claims.”
Novo Indus., L.P. v. Micro Molds Corp., 350 F.3d 1348, 1354 (Fed. Cir. 2003); see
also Hoffer v. Microsoft Corp., 405 F.3d 1326, 1331 (Fed. Cir. 2005) (“When a
harmless error in a patent is not subject to reasonable debate, it can be corrected by
the court, as for other legal documents.” (citation omitted)). Here, the error—the use
of the term “play gym” instead of “play yard”—is obvious from the face of the patent
and is not subject to reasonable debate. The ’993 patent repeatedly describes using
the play gym in two “modes”—in the first, the play gym is used inside the bassinet
and/or the play yard, as is demonstrated in Figure 1. ’993 Patent col. 2 ll. 36-39
(“[A]s shown in FIG. 1, the illustrated play gym 10 has a first mode in which it
17
suspends an object above the mat 16 when the mat is positioned in the bassinet 12
and/or the play yard 14.”). In the second mode, the play gym is used “above the mat
16, but not above the play yard 14 or the bassinet 12.” Id. col. 2 ll. 46-48; see also id.
col. 6 ll. 33-35 (noting that it may be “desired to use the mat 16 with the play gym
10 apart from the bassinet 12 and/or the play yard 14” (emphases added)). For
example, “the mat 16 [can be] positioned on another surface such as the floor of a
house.” Id. col. 2 ll. 43-44 (emphasis added). One part of the specification provides a
sensible explanation of the intent of the claim language:
If the user wishes to use the play gym 10 apart from the bassinet 12
and the play yard 14, the user may remove the play gym 10 from the
bassinet 12 and/or the play yard 14 … . If the user desires to use the
play gym 10 with the mat 16, the user may then remove the mat 16
from the bassinet 12 and/or the play yard 14 and position the mat 16 in
a desired location of use. … The user may then secure the play gym 10
to the floor mat 16 … .
Id. col. 7 ll. 10-24 (emphases added). The figures also show that the claim meant to
say “apart from the play yard” instead of “apart from the play gym.” Figure 2, see
supra Section I.B, shows the play gym used with only the mat, which is separated
from the play yard. Id. col. 2 ll. 1-3 (“FIG. 2 is a perspective view of the example
play gym of FIG. 1 when removed from the play yard and bassinet, and coupled to a
floor mat … .” (emphasis added)); id. col. 2 ll. 31-33 (“Additionally, the play gym 10
is structured to suspend the same or a different object above a mat 16 separate from
the bassinet 12 and the play yard 14 as shown in FIG. 2.” (emphasis added)). Thus,
the patent’s context would lead an ordinary artisan to understand that “securing
18
the play gym to a mat apart from the play gym” should say “securing the play gym
to a mat apart from the play yard.”
In
addition,
the
prosecution
history
does
not
suggest
a
different
interpretation of the claims. Artsana argues that the language in Claim 28 is not a
typo because the patent examiner rejected a similarly-worded claim in Kolcraft’s
original patent application and thus found that the prior art had already disclosed
the process of “securing the play gym to a mat apart from the play gym.” R. 158,
Def.’s Reply at 7-8. During patent prosecution, the patent examiner wrote the
following:
Claims 36 are rejected under 35 U.S.C. 102(b) as being anticipated by
4,188,745 to Harvey et al.
Claim 36, Harvey discloses a method comprising:
securing a play gym 10 to a play yard (col. 3 lines 14-17); such that the
play gym is connected to separate floor mat defined by a base 34 and
not in direct contact with a floor mat of the at least one bassinet and
the play yard;
removing the play gym from the play yard; removing the floor mat
from the play yard; and securing the play gym to the mat defined by the
base 34 apart from the play gym.
Joint App’x at JA-000051 (emphasis added). According to Artsana, the patent
examiner did not make a typographical error in writing “the play gym … apart from
the play gym,” and explicitly found that this was disclosed by the Harvey reference.
Def.’s Reply at 8. But a closer look at patent number 4,188,745 (the ’745 patent or
“the Harvey reference”) shows that this patent does not actually disclose “securing
the play gym to the mat defined by the base apart from the play gym,” whatever
19
that might mean. The Harvey reference discloses “[a]n infant toy for mounting on
an infant seat, car seat, infant bed, stroller, or the like.” R. 167, Def.’s Exh. A, ’745
Patent at [57]. That toy is made from plastic tubes forming an inverted-U shape; the
two legs of the toy then attach to two clamps connected to a base. Id. col. 1 ll. 35-47.
The toy can be removed from the base and then clamped on the two sides of a car
seat or infant seat. Id. col. 2 ll. 46-68. The Harvey patent also discloses clamping the
toy to the base, placing the base at the bottom of an infant bed, and then placing the
child above the flat base so that the child can play with the toy. Id. col. 3 ll. 1-18.
The portion of the specification cited by the patent examiner further explains that
“[w]hile an infant bed is shown, it could be appreciated that the toy 10 as shown in
FIG. 4 could also be used in a playpen, stroller, or any other flat surface used for
placing the infant thereon.” Id. col. 3 ll. 14-17. Below, Figure 1 shows the toy
attached to the base, and Figure 4 shows the toy and the base placed inside an
infant bed:
20
’745 Patent at 2.
But neither the patent examiner nor Artsana explains how the Harvey
reference specifically discloses “securing a play gym to a mat apart from the play
gym.” Instead, the patent examiner focused on Harvey’s disclosure of a toy that was
“clearly capable of being connected to the separate mat defined by a base 34 and
may not come into direct contact with a floor mat of the bassinet or the play yard
since the base 34 is capable of being placed on top of a flat surface such as a
mattress wherein the infant is placed on top of the flat base 34 while being used in a
playpen or bassinet.” Joint App’x at JA-000057. In other words, the Harvey
reference disclosed attaching the toy to a base other than the base of the play yard or
bassinet, which was described in this part of Kolcraft’s rejected Claim 36: “securing
a play gym 10 to a play yard … such that the play gym is connected to a separate
floor mat defined by a base 34 and not in direct contact with a floor mat of the at
least one bassinet and the play yard.” Joint App’x at JA-000051 (emphasis added).
But the patent examiner did not explain how this equated to “securing the play gym
to a mat apart from the play gym.” Thus, the patent prosecutor’s citation of the
Harvey reference does not show that the phrase “securing the play gym to a mat
apart from the play gym” was deliberate or had any significance.
Therefore, the context and specification of the ’993 patent show that Claim 28
intended to say “securing the play gym to a mat apart from the play yard and the
bassinet.” The Court modifies the claim accordingly, and there are no indefiniteness
problems with the new construction. E.g., Hoffer, 405 F.3d at 1331 (claim’s
21
reference to “claim 38” was a typo, where it was “apparent from the face of the
patent” that it meant to reference “claim 21”); Ultimax, 587 F.3d at 1350 (claim not
indefinite for including nonexistent chemical compound C9S3S3Ca(f cl)2, when it was
obvious that there should be a comma between fluorine and chlorine).
C. Pivoting the leg into a stored position
Next, Artsana argues that Claim 28’s last phrase, “‘pivoting the leg into a
stored position[,]’ must be construed to require that the leg be connected to a fixed
member, such as a shaft or a pin, and turned or rotated about the fixed member to a
stored position.” Def.’s Br. at 18. The parties agree that the “stored position”
requires the legs to be parallel to each other, as illustrated above in Figure 4. See
supra Section I.B; see Pl.’s Resp. at 23 (“[T]he phrase ‘stored position’ of claim 30
merely requires that the legs are positioned generally parallel to each other … .”);
Def.’s Reply at 11 n.4 (“Artsana agrees with Kolcraft that the phrase ‘stored
position’ in claims 28 and 30 should be construed to ‘require that the legs are
positioned generally parallel to each other … .’”). But Kolcraft argues that Artsana’s
construction is too limited; although Kolcraft does not offer a definition of “pivot,” it
essentially argues that any sort of movement of the legs satisfies the “pivoting”
requirement, as long as the legs are eventually parallel to each other. See Pl.’s Br.
at 23.
The Court construes this claim as requiring the leg to be turned or rotated
about a fixed point. The term “pivoting” must do some work; otherwise, the claim
could have said “moving the leg into a stored position.” The Court must place
22
importance on the terms in the claim, “for it is that language that the patentee
chose to use to ‘particularly point[ ] out and distinctly claim[ ] the subject matter
which the patentee regards as his invention.’” Interactive Gift Exp., Inc. v.
Compuserve Inc., 256 F.3d 1323, 1331 (Fed. Cir. 2001) (quoting 35 U.S.C. § 112(b)).
The patent specification also supports the interpretation that pivoting must mean
more than simply moving; it emphasizes the leg’s rotation around some fixed point,
such as a pin. The specification offers this example of how the play gym is
constructed: “[T]he hub 20 includes a plurality of pins 32. Each of the pins 32 is
positioned in a respective one of the slots. 30. The pins 32 and slots 30 are
dimensioned such that each of the legs 22 may pivot about its respective pin 32 … .”
’993 Patent col. 4 ll. 14-18. As a result, the legs often move along a fixed path
defined by that central anchoring point. See id. col 4 ll. 19-21 (“The permitted slide
distance is defined by the size of the corresponding slot 30 and pin 32.”); id. col. 8 ll.
29-32 (claiming an apparatus where the “legs must be moved along its longitudinal
axis”). Below, the cross-sectional figures show the action of pivoting around a pin
(the pin is highlighted in yellow). The figures portray the legs in the stored
(parallel) position (Figure 7), in movement towards the extended position (Figure 8),
and in the extended position (Figure 9):
23
Id. at Sheet 5. In these figures, the leg (part 22) moves from the extended to the
closed positions by rotating around a pin (part 32), which is fixed to the central hub.
It is true, as Kolcraft points out, that the specification states that “the legs 22 may
be coupled to the hub 20 in any number of ways,” and not necessarily with a pin. Id.
col. 4 ll. 12-13. But the specification’s examples and the repeated use of the word
“pivot,” which must be ascribed its ordinary meaning, suggest that even if the leg is
24
not moving around a pin, it must be around some sort of fixed point involving a
hinge, joint (such as ball and socket), or other similar mechanism.
This construction is also supported by the dictionary definition of “pivot”: “a
shaft or pin on which something turns.” R. 146-1, Def.’s Exh. A, Merriam-Webster
at 1. The verb “pivot” similarly means “to turn on or as if on a pivot.” Id. at 2. This
definition emphasizes that something moves or turns around some other fixed point.
Kolcraft, however, argues that the verb definition of “pivot” is broader than the
noun definition because the former includes turning “as if on a pivot,” so it does not
necessarily require turning “on a pivot.” Pl.’s Resp. at 20-21. But this argument is
rejected for two reasons. Mostly importantly, the dictionary definition, which is
extrinsic evidence, must “not contradict any definition found in or ascertained by a
reading of the patent documents,” Vitronics, 90 F.3d at 1584 n.7, and Kolcraft’s
reading of the definition is inconsistent with the ’993 patent’s specification and
claims, as explained above. Plus, it is not even clear that Kolcraft’s interpretation of
the verb definition is correct. “Pivot” as a noun is defined as “a shaft or pin on which
something turns,” Merriam-Webster at 1, and “as if on a pivot” simply refers to an
action that mimics the rotation around a shaft or pin, without necessarily involving
a shaft or a pin. For instance, the dictionary gives this example of pivoting: “The
quarterback pivoted and threw the ball to the running back.” Id. at 2 (emphasis
omitted). Although there is no shaft or pin involved (unless the quarterback has had
some drastic ankle surgery), the quarterback is moving one foot while keeping the
other fixed to the ground—in other words, pivoting. See also id. at 1 (“the action of
25
pivoting” includes “stepping with one foot while keeping the other foot at its point of
contact with the floor”). So the dictionary definition of “pivot” supports the
movement around some fixed point, a meaning that is also reinforced by the
specification language and drawings.
D. Moving the leg of the play gym toward the hub to secure the leg in the
stored position
The parties also dispute the meaning of the following phrase in Claim 30:
“moving the leg of the play gym toward the hub to secure the leg in a stored
position.” ’993 Patent col. 10 ll. 23-24. The main dispute is what is meant by the
phrase “to secure the leg” in a stored position. (Remember that the parties do agree
that the “stored position” means that the legs are parallel to one another.) Artsana
argues that “to secure the leg” means that the leg is substantially fixed or
immovable without the application of a countervailing force to remove it from that
stored position. Def.’s Br. at 21-23. Kolcraft argues that this goes far beyond the
meaning of the word “secured,” which simply “requires that the legs are positioned
generally parallel to each other … .” Pl.’s Resp. at 23.9
The Court rejects Kolcraft’s construction because it would render useless the
word “secure,” and again, the Court must give weight to the words that the patentee
chose to use. See Interactive Gift, 256 F.3d at 1331. If the claim simply meant
placing the legs in a parallel position, then the claim could have said “moving the
9Artsana
also argues that the term “toward” must “be construed to require that the
leg of the play gym be displaced toward the hub; it cannot be displaced away from the hub
in the stored position.” Def.’s Br. at 21. But the meaning of the word “toward” is not in
dispute and Artsana does not explain why any elaboration on the word “toward” is needed,
so the ordinary meaning applies.
26
leg of the play gym toward the hub in a stored position,” without any mention of
securing the leg in a stored position. The patent specification also supports the
interpretation that the legs are fixed in place. In describing the stored and extended
positions, the specification provides that the hub can have “a plurality of cavities,
40, 44. A first set of the cavities 40 is positioned to prevent the legs 22 from pivoting
when the legs 22 are in the stored position. The second set of cavities 44 is
positioned to prevent the legs 22 from pivoting when the legs 22 are in the extended
position.” ’993 Patent at col. 4 ll. 35-39; see also id. col. 4 ll. 49-54 (explaining that in
the stored position, the cavity walls “prevent the leg 22 from pivoting out of the
stored position”). The cavities are pockets of space that enclose the end of the leg
and keep the leg from budging. Below, they are shaded in yellow and shown in the
stored position (Figure 7) and in the extended position (Figure 9):
27
While in the cavities, the legs cannot move on their own, so a user must apply some
force to move the legs between the extended and stored positions: “[A] user must
pull that leg 22 against the force of the spring 36 a distance away from the hub 20
such that the end of the leg 22 can be pivoted out of one of the cavities 40, 44 and
into the other one of the cavities 40, 44 … .” Id. col. 4 ll. 58-62; id. col. 7 ll. 29-38
(“To move a leg 22 to the stored position, the user may pull the leg 22 … in a
direction away from the hub 20” and then “pivot the leg 22 … and permit the spring
36 to pull the end of the leg 22 into the corresponding cavity 40 … into the stored
position.”); id. col. 4 ll. 30-33 (“In other words, the springs 36 force their respective
legs 22 toward the hub 20 unless a countervailing force is applied pulling the legs
away from the hubs 20.” (emphasis added)).
What’s more, the term “secure” should be interpreted consistently throughout
the claim language, and the Court explained earlier that “securing a play gym at
least partially above at least one of a bassinet and a play yard” means that the play
gym must be connected to, attached to, or otherwise in direct contact with the play
yard, bassinet, or mat, such that the play gym’s legs are arched in a fixed position.
See supra Section III.A; Phillips v. AWH Corp., 415 F.3d 1303, 1314 (Fed. Cir. 2005)
28
(“Because claim terms are normally used consistently throughout the patent, the
usage of a term in one claim can often illuminate the meaning of the same term in
other claims.” (citations omitted)). It would be inconsistent to now read “secure” to
mean that the legs are simply placed in a parallel position, without requiring that
the legs be fixed. Similarly, the dictionary definition of “secure” is to “put
(something) in a place or position so that it will not move,” Merriam-Webster Online

way, fall off, or come apart; to hold firmly in place; to fasten or do up; to close (a
door, window, etc.) tightly; to lock.”). Thus, the Court construes “secur[ing] the leg
in a stored position” to mean that the legs are positioned generally parallel to each
other, and are substantially fixed without the application of a countervailing force
to remove it from this position.10
10Kolcraft
argues that no construction is necessary for almost all of the disputed
terms in Claims 28 and 30 (except for the phrase in Claim 28 involving a typographical
error), because the claims should be given their plain and ordinary meaning. See generally
R. 150, Pl.’s Resp. But the interpretations described in this Opinion do give further
meaning to the disputed terms, and without the further elaboration, the parties would still
dispute what is meant by the supposedly “ordinary” meaning. See Eon Corp. IP Holdings v.
Silver Spring Networks, 815 F.3d 1314, 1318 (Fed. Cir. 2016) (“[a] determination that a
claim term ‘needs no construction’ or has the ‘plain and ordinary meaning’ may be
inadequate when a term has more than one ‘ordinary’ meaning or when reliance on a term’s
‘ordinary’ meaning does not resolve the parties’ dispute” (citation and quotations omitted)).
29
E. Order of Steps in Claim 28
Finally, Artsana argues that the steps in Claim 28 must be performed in the
precise order in which they are listed. Def.’s Br. at 9-10. The Court reproduces
Claim 28 below, numbering the steps for ease of reference only:
(1) securing a play gym at least partially above at least one of a
bassinet and a play yard;
(2) removing the play gym from the at least one of the bassinet and the
play yard;
(3) securing the play gym to a mat apart from the play gym play yard
and the bassinet;
(4) removing the play gym from the mat; and
(5) collapsing the play gym, wherein collapsing the play gym
comprises:
(6) pulling a leg of the play gym in a direction away front a hub; and
(7) pivoting the leg into a stored position.
’993 Patent col. 10 ll. 6-18.
The Court disagrees that the seven steps must be performed in this precise
order. “Unless the steps of a method actually recite an order, the steps are not
ordinarily construed to require one.” Interactive Gift, 256 F.3d at 1342-43 (citations
omitted). To be sure, there are some exceptions; one is “if, as a matter of logic or
grammar, [the claims] must be performed in the order written.” Altiris, 318 F.3d at
1369 (citations omitted). “If not, [the Court] next look[s] to the rest of the
specification to determine whether it directly or implicitly requires such a narrow
construction.” Id. (emphasis in original) (citation and quotations omitted). If there is
30
no such requirement in the specification, then the steps need not be performed in
the order in which they were written in the claims. Id.
The parties agree that the steps in Claim 28 are not explicitly ordered. There
is no statement that the steps need to be performed in a certain order, and the steps
are not numbered or otherwise sequenced. Nor does logic nor grammar require that
the steps be performed in the order that they are listed. For example, a user can:
secure the play gym to the mat placed on the floor (step 3); remove the play gym
from the mat (step 4); secure the play gym to the bassinet and/or play yard (step 1);
remove the play gym from the bassinet and/or play yard (step 2); and then collapse
and store the play gym (steps 5, 6, and 7). Or, the user can secure the play gym to
the mat placed on the floor (step 3); remove the play gym from the mat (step 4);
collapse and store the play gym (steps 5, 6, and 7); set up the play gym again and
secure it to the bassinet and/or play yard (step 1); and remove the play gym from
the bassinet and/or the play yard (step 2). Another possibility: secure the play gym
to the mat inside the play yard (step 1); remove the mat from the play yard, with
the play gym still attached to the mat (step 2); remove the play gym from the mat
(step 4); collapse the play gym (steps 5, 6, and 7); and then set up the play gym and
secure it to only the mat (step 3).
In addition, nothing in the specification directly or implicitly requires the
steps to be completed in the order listed. In fact, the opposite is true: the whole
purpose of the patent is versatility. The user has the flexibility to use the products
in any manner and order that suits his or her needs, and the products can be used
31
in several combinations. E.g., ’993 Patent col. 2 ll. 34-36 (explaining that the mat
can be used with both the bassinet and the play yard); id. col. 3 ll. 9-13 (same); id.
col. 3 ll. 36-42 (same); id. col. 5 ll. 9-4-15 (explaining that the play gym can be used
with the bassinet or play yard); id. col. 5 ll. 43-47 (explaining that the play gym can
be directly connected to the mat). Requiring the products to be used in the order
listed—that is, first using the play gym with the play yard and/or bassinet, then
using the play gym with only the mat, then collapsing the play gym, and then
repeating the same cycle again—defies the day-to-day realities of how someone
would care for a child and use these products.
Artsana’s main argument in favor of the specific order is not in its briefs, but
was raised in the Markman hearing: because step 1 refers to “a play gym,” “a
bassinet,” and “a play yard,” and because steps 2-7 then refer to “the play gym,” “the
bassinet,” and “the play yard,” the use of the word “the” necessarily refers to the
specific products in step 1. R. 176, 2/19/13 Hr’g Tr. 9:21-10:4. And reference to an
antecedent, as the argument goes, only makes sense if the steps are to be performed
in order. Id. For support, Artsana cites NTP, Inc. v. Research In Motion, Ltd., 418
F.3d 1282, 1306 (Fed. Cir. 2005), which cited this proposition in a parenthetical:
“[A] preamble usually does not limit the scope of the claim unless the preamble
provides antecedents for ensuing claim terms and limits the claim accordingly.”
(quoting C.R. Bard, Inc. v. M3 Sys., Inc., 157 F.3d 1340, 1350 (Fed. Cir. 1998)
(quotations omitted)); R. 167, Def.’s Post Hr’g Br. at 1-2. In NTP, because the
preamble of the claim included the phrase “a plurality of destination processors in
32
the electronic mail system,” the claim’s later mention of “the at least one of the
plurality of destination processors” was a reference to the destination processor in
the preamble. 418 F.3d at 1306. But NTP is not directly applicable here because the
Federal Circuit was not explaining the ordering of steps, but rather that the
limitations in a patent’s claim “derive[d] their antecedent basis from the claim[’s] []
preamble.” Id. (citation omitted). Here, there is no preamble in Claim 28; and in any
event, it is undisputed that the play gym, play yard, bassinet, and mat mentioned
throughout the claim refer to the same play gym, play yard, bassinet, and mat. So
NTP does not help Artsana. Nor is W.L. Gore & Associates, Inc. v. Medtronic, Inc.,
874 F. Supp. 2d 526 (E.D. Va. 2012), another case Artsana cites, applicable; there,
the district court held that the plain language of claims 12 and 15 of the ’870 patent
required a sequential order. But the steps in those claims were actually sequenced
by a, b, c, and so on, and the logic of the claim language matched the ordered
sequence. Id. at 532, 547-48. Again, that is not the case here. In sum, Artsana’s
hyper-technical argument—that the word “the” refers to some antecedent, and thus
implies an order—cannot overcome the explicit text of Claim 28, which requires no
order, and the implicit focus of the specification, which focuses on the versatility
and flexibility of the products.11
11In
a footnote, Artsana string cites a few more cases allegedly supporting the
antecedent argument, but does not elaborate on how these cases are directly analogous.
