SUMMARY**
Copyright
The panel affirmed the district court’s dismissal of a
claim of trade dress infringement, reversed the district
court’s dismissal of a claim of infringement of copyright in
kinetic and manipulable sculptures, and remanded.
As to the copyright claim, the panel held that, at the
pleading stage, the plaintiff adequately alleged valid
copyrights in seven kinetic and manipulable sculptures.
Comparing the plaintiff’s works to dance, movies, and
music, the panel held that the fact that the works moved into
various poses did not, by itself, support the conclusion that
they were not “fixed” in a tangible medium for copyright
purposes. The panel also held that, under the “extrinsic test,”
the plaintiff validly alleged copying of its protected works
because it plausibly alleged that the creative choices it made
in selecting and arranging elements of the works were
substantially similar to the choices the defendants made in
creating their own sculptures.
As to the claim of trade dress infringement under the
Lanham Act, the panel affirmed the district court’s dismissal
for failure to give adequate notice of the asserted trade dress.

OPINION
SIMON, District Judge:
This appeal primarily involves the copyrightability of
kinetic and manipulable sculptures, which is an area of
copyright law that has not yet received much attention. We
reverse the district court’s dismissal of the plaintiff’s
copyright claim and hold that, at the pleading stage, the
plaintiff has adequately alleged valid copyrights and has
adequately alleged copying of its protected works.
Ultimately, the copyright analysis applicable to the kinetic
and manipulable sculptures at issue in this case may be better
informed with a more complete factual record.
I.
As relevant here, Plaintiff-Appellant Tangle, Inc.
(“Tangle”) holds copyright registrations for seven kinetic
and manipulable sculptures. Each sculpture is made from
4 TANGLE, INC. V. ARITZIA, INC.
either 17 or 18 identical, connected, 90-degree curved
tubular segments (i.e., one-quarter of a torus), typically
made of chrome, that can be twisted or turned 360 degrees
where any two segments connect. By twisting or turning a
segment, the sculpture can be manipulated to create many
different poses.
Defendants-Appellees Aritzia, Inc., Aritzia, L.P., and
United States of Aritzia, Inc. (collectively, “Aritzia”) own
and operate approximately 121 upscale retail stores in the
United States and Canada that sell “lifestyle apparel.” In
2023, Aritzia decorated its retail store windows with eye-
catching sculptures made with 18 identical, connected, 90-
degree curved tubular segments that can be twisted or turned
360 degrees where any two segments connect. In contrast to
Tangle’s copyrighted sculptures, however, Aritzia’s
sculptures were substantially larger and taller, and were of a
different color, than Tangle’s copyrighted works.
Additionally, Aritizia’s sculptures had a chrome finish,
whereas all but one of Tangle’s registered works have a
matte finish.
In its original complaint, Tangle alleged only copyright
infringement, under the Copyright Act of 1976—
specifically, 17 U.S.C. § 501(a). Aritzia moved to dismiss
for failure to state a claim under Rule 12(b)(6) of the Federal
Rules of Civil Procedure. After the district court granted
Aritzia’s motion with leave to replead, Tangle filed an
amended complaint, still alleging only copyright
infringement. Aritzia then moved to dismiss Tangle’s
amended complaint. The district court granted that motion,
again giving Tangle leave to replead. Tangle then filed a
Second Amended Complaint (“SAC”), which is the
operative pleading.
TANGLE, INC. V. ARITZIA, INC. 5
In its SAC, Tangle continued to allege copyright
infringement but also added—for the first time—a claim of
trade dress infringement, under the Lanham Act—
specifically, 15 U.S.C. § 1125(a). Aritzia moved to dismiss
both claims under Rule 12(b)(6). The district court granted
Aritzia’s motion, dismissed both claims, and gave Tangle
leave to file a third amended complaint. Tangle, however,
declined to replead. Instead, Tangle gave formal notice of its
intent not to amend, electing the procedure described in
Edwards v. Marin Park, Inc., 356 F.3d 1058, 1065 (9th Cir.
2004) (explaining that after a district court dismisses a
complaint under Rule 12(b)(6) with leave to replead, if the
plaintiff “timely responds with a formal notice of [its] intent
not to amend, the threatened dismissal merely ripens into a
final, appealable judgment”). Based on Tangle’s timely
notice of its intent not to amend, the district court entered an
order dismissing both claims with prejudice, from which
Tangle now appeals. The district court’s decision well
summarizes the facts and shows the photographs of both sets
of sculptures, Tangle’s and Aritzia’s, that were included in
the SAC. See Tangle, Inc. v. Aritzia, Inc., 698 F. Supp. 3d
1180 (N.D. Cal. 2023).
We have jurisdiction under 28 U.S.C. § 1291. We review
de novo a district court’s dismissal for failure to state a claim
under Rule 12(b)(6). See Hanagami v. Epic Games, Inc., 85
F.4th 931, 938 (9th Cir. 2023) (citing Wilson v. Lynch, 835
F.3d 1083, 1090 (9th Cir. 2016)). For the reasons explained
below, we reverse the district court’s dismissal of Tangle’s
copyright claim but affirm the district court’s dismissal of
Tangle’s claim of trade dress infringement.
6 TANGLE, INC. V. ARITZIA, INC.
II.
To state a claim for copyright infringement, Tangle must
plausibly allege (1) that it owns a valid copyright in its
sculptural works, and (2) that Aritzia copied protected
aspects of Tangle’s expression. Feist Publ’ns, Inc. v. Rural
Tel. Serv. Co., 499 U.S. 340, 361 (1991).
Regarding the first element, Aritzia argues that Tangle’s
registered copyrights for its kinetic and manipulable
sculptures are valid only to the extent they seek protection
for specific poses, but not for the works’ full range of
motion. Aritzia contends that moveable sculptures, no matter
how original, can be the subject of a valid copyright only in
specific poses because they are otherwise not “fixed in any
tangible medium of expression,” as required by the
Copyright Act. 17 U.S.C. § 102(a). We disagree.
Under § 102 of the Copyright Act, “[c]opyright
protection subsists . . . in original works of authorship fixed
in any tangible medium of expression . . . from which they
can be perceived, reproduced, or otherwise communicated,
either directly or with the aid of a machine or device.” Id.
Works of authorship include “sculptural works.” Id.
§ 102(a)(5). Section 102 concludes, however: “In no case
does copyright protection for an original work of authorship
extend to any idea, procedure, process, system, method of
operation, concept, principle, or discovery, regardless of the
form in which it is described, explained, illustrated, or
embodied in such work.” Id. § 102(b).
That limitation, “along with the need to ‘fix’ a work in a
‘tangible medium of expression,’ have often led courts to
say, in shorthand form, that, unlike patents, which protect
novel and useful ideas, copyrights protect ‘expression’ but
TANGLE, INC. V. ARITZIA, INC. 7
not the ‘ideas’ that lie behind it.” Google LLC v. Oracle Am.,
Inc., 593 U.S. 1, 18 (2021). As we explained in Hanagami:
[A] defendant cannot be held liable for
copying only “ideas” or “concepts” from a
plaintiff’s work. Instead, to be liable for
copyright infringement, a defendant
“must . . . copy enough of the plaintiff’s
expression of those ideas or concepts to
render the two works ‘substantially similar.’”
85 F.4th at 941 (quoting Rentmeester v. Nike, Inc., 883 F.3d
1111, 1119 (9th Cir. 2018), overruled in part by Skidmore v.
Zeppelin, 952 F.3d 1051 (9th Cir. 2020) (en banc) (second
alteration in original)).
Contrary to Aritzia’s assertions, the fact that Tangle’s
works move into various poses does not, by itself, support
the conclusion that they are not “fixed” for copyright
purposes.1 See, e.g., Hanagami, 85 F.th at 935 (“Dance is
one of the oldest forms of human expression. Recognition of
dance as a form of copyrightable subject matter, however, is
a far more recent development.”). A motion picture “moves”
from frame to frame, as does a symphony, from note to note,
yet both can be protected under copyright law. Light and
sound, of course, are intangible, so movies and symphonies
must be reduced to the print of a film or score to achieve
sufficient fixation “in a tangible medium.” But that does not
detract from the fact that the core, copyrightable expression
of such works involves motion. Also, we are unaware of any
appellate case holding that expression involving motion, like
1
Indeed, such a rule could foreclose copyright protection for scores of
works from seminal artists such as Alexander Calder, Jean Tinguely, and
George Rickey.
8 TANGLE, INC. V. ARITZIA, INC.
a moveable sculpture, per se cannot be afforded copyright
protection because it is not “fixed.”2
Like dance, movies, and music, a moveable sculpture
like Tangle’s is sufficiently “fixed” to be entitled to
copyright protection, even when its pose changes. Under the
Copyright Act, a work is “‘fixed’ in a tangible medium of
expression when its embodiment in a copy . . . is sufficiently
permanent or stable to permit it to be perceived, reproduced,
or otherwise communicated for a period of more than
transitory duration.” 17 U.S.C. § 101. “Copies” are simply
“material objects . . . in which a work is fixed . . . .” Id. As
explained by Professor Jani McCutcheon:
Is there a fundamental barrier to a changeable
creation being a work? I think the answer is
no. The work can be identified in a volatile,
changeable creation, because the volatile,
changeable creation is the work. If the work
is, in essence, the author’s mental conception,
there is no fundamental obstacle to the author
conceiving a moving, shape-shifting thing.
2
The extensive body of copyright decisions has not yet seen many cases
involving the copyrightability of kinetic and manipulable sculptures. In
their briefs, both sides discuss the Seventh Circuit’s decision in Kelley v.
Chicago Park District, 635 F.3d 290 (7th Cir. 2011), a case that involves
the copyrightability of a garden, which—like all natural gardens—grows
and eventually dies. Although Kelley is both factually and legally
distinguishable from the situation here, one aspect of that case is
instructive. The issues in Kelley reached the Seventh Circuit after a trial
on the merits, id. at 295, not at the pleading stage. Here, this case reaches
us at the pleading stage, after the district court granted Aritzia’s motion
to dismiss and Tangle declined to replead a third time. As in Kelley, a
more fully developed factual record may assist the ultimate analysis of
the copyright issues presented.
TANGLE, INC. V. ARITZIA, INC. 9
The copy is just a record of the author’s
intellectual conception, whether motile or
not. Do the definitions of “copy” or “fixed”
mandate stasis? Again, the answer is no. The
Act does not require the copy to be inert. A
copy is the “material object . . [and]
[m]aterial things may move and change
shape.
Jani McCutcheon, Shape Shifters: Searching for the
Copyright Work in Kinetic Living Art, 64 J. COPYRIGHT
SOC’Y USA 309, 337-38 (2017) (footnotes omitted;
emphasis added). Here, Tangle’s sculptures are material
objects, so they qualify as “copies.” See 17 U.S.C. § 101. In
addition, those material objects can be “perceived” and
“reproduced” for more than a “transitory” period. See id. As
embodied in the sculptures, Tangle’s expression therefore is
“‘fixed’ in a tangible medium,” even though the sculpture
may take different poses. Tangle’s registered copyrights are
thus valid and protect its works across their full range of
motion.
We next address the second element of Tangle’s
copyright infringement claim—whether Aritzia has copied
protected aspects of Tangle’s expression. This element has
“two distinct components: ‘copying’ and ‘unlawful
appropriation.’” Rentmeester, 883 F.3d at 1117 (collecting
authorities). Here, Aritzia does not dispute that Tangle has
adequately alleged copying of its copyrighted sculptures.
To establish unlawful appropriation, a plaintiff must
demonstrate that the allegedly infringing work and the
copyrighted expression “share substantial similarities.”
Skidmore, 952 F.3d at 1064 (citing Newton v. Diamond, 388
F.3d 1189, 1193 (9th Cir. 2004)). “[W]e use a two-part test
10 TANGLE, INC. V. ARITZIA, INC.
to determine whether the defendant’s work is substantially
similar to the plaintiff’s copyrighted work.” Id. (citing
Cavalier v. Random House, Inc., 297 F.3d 815, 822 (9th Cir.
2002)). At the pleading stage, a court may only apply the
first part of the test, what we call the “extrinsic test.”3 This
“assesses the objective similarities of the two works,
focusing only on the protectable elements of the plaintiff’s
expression.” Rentmeester, 883 F.3d at 1118. In essence, this
test asks whether—based on articulable, objective factors—
any reasonable juror could find that the allegedly infringing
work is substantially similar to the copyrighted expression.
See Cavalier, 297 F.3d at 822. The extrinsic test thus serves
to screen out objectively meritless claims, so courts can
apply it as a matter of law. See Rentmeester, 883 F.3d at
1118. However, “because most judges are not sufficiently
trained in the specifics of the art form at issue to make
reliable conclusions about similarity” without the benefit of
expert testimony, it is “generally disfavored for copyright
claims to be dismissed for lack of substantial similarity at the
pleading stage.” Hanagami, 85 F.4th at 945 (citing Williams
v. Gaye, 895 F.3d 1106, 1119 (9th Cir. 2018)).
Applying the extrinsic test requires that we first
determine whether a work contains “protectable elements”
3
The second part, known as the “intrinsic test[,] requires a more holistic,
subjective comparison of the works to determine whether they are
substantially similar in ‘total concept and feel.’” Rentmeester, 883 F.3d
at 1118 (quoting Cavalier, 297 F.3d at 822). In contrast to the extrinsic
test—which asks only whether a reasonable juror could find substantial
similarity based on objective metrics—the intrinsic test asks whether a
particular factfinder does find the two works to be substantially similar
as a subjective matter. As such, “the intrinsic test is reserved exclusively
for the trier of fact.” Williams v. Gaye, 895 F.3d 1106, 1119 (9th Cir.
2018). Because this case comes to us at the pleading stage, we deal only
with the extrinsic test.
TANGLE, INC. V. ARITZIA, INC. 11
under the Copyright Act. To do so, we must “‘filter out’ the
unprotectable elements of the . . . work—primarily ideas and
concepts, material in the public domain, and scènes à faire
(stock or standard features that are commonly associated
with the treatment of a given subject).” Rentmeester, 883
F.3d at 1118. “Still, ‘substantial similarity can be found in a
combination of elements, even if those elements are
individually unprotected.’” Williams, 895 F.3d at 1119–20
(quoting Swirsky v. Carey, 376 F.3d 841, 848 (9th Cir.
2004)). Here, the individual elements of Tangle’s
sculptures—the number of segments, the uniformity of those
segments, their exact shape and proportions, the end-to-end
connection of the segments in a closed loop, and their
connection via joints that allow the segments to be turned
360 degrees—may be unprotected “when viewed in
isolation.” Rentmeester, 883 F.3d at 1119. But “[w]hat is
protectable is [Tangle]’s ‘selection and arrangement of the
[sculpture’s] otherwise unprotected elements.’” Hanagami,
85 F.4th at 943 (quoting Rentmeester, 883 F.3d at 1119).
That original “combination” of the number, uniformity,
shape, proportion, and mode of connection of the segments
is what “receives protection, not any of the individual
elements standing alone.” Rentmeester, 883 F.3d at 1119.
Further, Tangle’s particular arrangement of those elements
enjoys “broad” copyright protection because a “wide range
of possible expression” can result from different choices
about the number, shape, and proportions of segments used
in a sculptural work, whether to make the segments uniform,
and how to connect them. See Hanagami, 85 F.4th at 947.
Thus, to establish that Aritzia unlawfully appropriated
Tangle’s protected expression, Tangle need only show that
12 TANGLE, INC. V. ARITZIA, INC.
Aritzia’s allegedly infringing sculptures are “substantially
similar” to Tangle’s copyrighted works. Id.4
Next, we must “compare the selection and arrangement
of elements in the registered . . . work[s] with that in the
allegedly infringing work[s]” to determine whether Tangle
has alleged substantial similarity. Id. at 944. We hold that
Tangle “has plausibly alleged that the creative choices [it]
made in selecting and arranging elements of [the protected
works] . . . are substantially similar to the choices [Aritzia]
made in creating” its sculptures. See id. at 945. Tangle has
alleged that Aritzia’s sculptures, just like Tangle’s, are made
from 18 identical, connected, 90-degree curved tubular
segments (i.e., one quarter of a torus) that can be twisted or
turned 360 degrees where any two segments connect,
allowing the sculpture to be manipulated to create many
different poses. That is enough to allow Tangle’s copyright
claim to proceed past the pleading stage. Although Tangle’s
and Aritzia’s sculptures may differ in other respects, like
their overall size or specific poses, the works are “similar
enough that ‘the ordinary observer, unless he set out to detect
the[se] disparities, would be disposed to overlook them.’”
Rentmeester, 883 F.3d at 1121 (quoting Peter Pan Fabrics,
Inc. v. Martin Weiner Corp., 274 F.2d 487, 489 (2d Cir.
4
Aritzia argues that Tangle’s sculptures “contain[] only a narrow range
of possible expression and a limited range of creative choices,” so they
have “‘thin’ copyright protection, and infringement occurs only if
another work is ‘virtually identical’ to [them].” Hanagami, 85 F.4th at
947 (quoting Mattel, Inc. v. MGA Ent., Inc., 616 F.3d 904, 913–14 (9th
Cir. 2010)). A more complete record may show that the sculptural
elements can be combined only in a few ways and that Tangle’s works
are infringed only by “virtually identical” arrangements. See id. at 948.
But for now, a showing of substantial similarity will suffice for Tangle’s
claim to proceed.
TANGLE, INC. V. ARITZIA, INC. 13
1960)). Perhaps discovery and expert opinions may clarify
these issues, and perhaps a jury may need to decide whether
Aritzia’s sculptures are substantially similar to Tangle’s
sculptures under the intrinsic test. See id. at 1118. But these
are questions best saved for a later day. Accordingly, we
reverse the district court’s dismissal of Tangle’s claim of
copyright infringement.
III.
The district court also dismissed Tangle’s first—and
only—pleading of its claim of trade dress infringement,
stating that Tangle did not give adequate notice of its
asserted trade dress. 5 The district court held that Tangle
failed to allege a complete recitation of the concrete
elements of its alleged trade dress. The district court
explained that “[b]ecause trade dress claims involve
intensely factual issues, courts in this circuit have required
trade dress plaintiffs, at the very least, to provide adequate
notice by including in their complaint a complete recitation
of the concrete elements of their alleged trade dress.”
Tangle, 698 F. Supp. 3d at 1189 (quoting YZ Prods. v.
Redbubble, Inc., 545 F. Supp. 3d 756, 767 (N.D. Cal. 2021)).
A product’s trade dress consists of “its total image and
overall appearance; it includes ‘features such as size, shape,
color, color combinations, texture, or graphics.’” Kendall-
Jackson Winery, Ltd. v. E. & J. Gallo Winery, 150 F.3d
1042, 1044 n.2 (9th Cir. 1998) (quoting Vision Sports, Inc.
v. Melville Corp., 888 F.2d 609, 613 (9th Cir. 1989)).
5
As noted, Tangle alleged trade dress infringement for the first time in
its SAC. It did not assert a trade dress infringement claim in its original
complaint or first amended complaint.
14 TANGLE, INC. V. ARITZIA, INC.
Tangle responds that its SAC offers illustrative
photographs of its pink chrome trade dress and alleges that
the bright pink color and chrome finish are identical to that
used in Aritzia’s infringing sculptures. Tangle adds that this
chrome finish and color combines with other creative
decisions, including interlocking, 90-degree curved pieces
of approximately 18 constituent parts. As the district court
in YZ Productions noted, however, “‘images and
descriptions . . . of some . . . products are alone insufficient
to put [the defendant] on notice of the asserted trade dress’;
rather, a complete recitation of the concrete elements of the
trade dress is required.” 545 F. Supp. 3d at 767 (alteration
and omissions in original) (first citing Crafty Prods., Inc. v.
Michaels Cos., Inc., 424 F. Supp. 3d 983, 991–92 (S.D. Cal.
2019), aff’d sub nom. Crafty Prods., Inc. v. Fuqing Sanxing
Crafts Co., 839 F. App’x 95 (9th Cir. 2020); and then
quoting Mosaic Brands, Inc. v. The Ridge Wallet LLC, No.
220CV04556ABJCX, 2020 WL 5640233, at *5 (C.D. Cal.
Sept. 3, 2020)). We agree and so hold.
Tangle, however, failed to provide a complete recitation
of the concrete elements that it contended constituted its
protectible trade dress, and merely providing photographs of
some products and partial descriptions is insufficient. The
district court so informed Tangle and gave Tangle an
opportunity to replead, which Tangle declined. The district
court did not err in dismissing Tangle’s trade dress claim
with prejudice. Accordingly, we affirm that portion of the
district court’s decision.
