Abstract: Since the 1990s, the popularity of Internet technology has promoted the rise of Fan Fiction creation platform,
but Fan Fiction, based on the characteristics of original works, have been in the gray area of copyright disputes
for a long time. This article focuses on non-deductive Fan literature works and conducts research on their
infringement determination and fair use issues. Research suggests that in the determination of infringement,
the copyright ability of virtual characters needs to be analyzed through each case study based on the “idea-
expression dichotomy”. The determination of substantial similarity requires a comprehensive analysis of
overall perception and elements. In the defense of fair use, the theory of “transformative use” and market
substitution evaluation are key. Fan Fictions can enhance their transformability, while their non-profit and
cultural dissemination functions reduce market substitution risks, and it is not simply judged by whether they
constitute fair use based on profitability or not. The conclusion points out that the existing law lacks clear
provisions on the boundaries of role copyright and fair use standards. In the future, it is necessary to clarify
the scope of protection of virtual roles in legislation and improve the system of fair use.
1 INTRODUCTION
Since the 1990s, with the continuous development of
the Internet and the growth and maturity of online
communities, the co-creation platform represented by
AO3 (Archive of Our Own) and Lofter has
constructed a new creation ecology of online
literature. The popularization of social media and We
media tools makes “user-generated content (UGC)”
break through the traditional publishing barriers, and
a large number of fellow enthusiasts gather on the
platform and communicate in real time. This
“participatory culture” reconstructs the subjectivity
of literary creation, brings about the rise of co-literary
works, and also brings about a series of copyright
problems due to its particularity based on the original
works (Jenkins, 2016).
There are obvious gaps in the current legal
regulation of fan fictions.
On the one hand, the existing laws and regulations
do not clarify the legal status of the fan fiction, and
the characteristics of the fan fiction based on the
original work make them stay in the gray area for a
long time, resulting in long-term disputes over the
legality and infringement of the characters and plots
of the original work.
On the other hand, the law lacks a clear definition
of the boundary between the rights of the original
author and the fan author, and the ambiguity of the
law leads to an increase in the cost of rights
protection. A large number of fan literature works are
likely to harm the legitimate rights and interests of the
original author, while fan authors also face the
dilemma of unclear infringement boundaries, causing
them to worry about whether their creative behavior
is legal and, to some extent, suppressing their creative
enthusiasm.
This article mainly focuses on the issue of
infringement determination and fair use of fan fiction.
2 THE DEFINITION AND
CLASSIFICATION OF FAN
FICTION AND THEIR DISPUTE
2.1 Definition of Concepts
Fan fiction originates in Japan, where the anime
culture is prosperous, and includes various forms
such as paintings, novels and videos. As an imported
word, its conceptual definition has not formed a
unified standard. Generally speaking, it is defined as

a form of creation that is not influenced by
commercial factors, does not aim for profit, and uses
the original as the basis for secondary creation.
The fan fiction works discussed in this article are
one of the main forms of expression of fan fiction, and
their core feature is that they are secondary creations
based on original elements (characters, background,
plot), mainly non-profit.
2.2 Classification
According to the different themes and types reflected
in the relationship between fan fiction and the original
works, the author thinks that they can be mainly
divided into deductive fan fiction and non-deductive
fan fiction.
2.2.1 Deductive Fan Fiction
Such works are rewritten or continued with the
original as the blueprint, such as writing a new ending
for a classical novel and supplementing the branch
plot that has not been expanded in the original work.
The most typical example is Gao E's continuation of
The Story of the Stone (Wang, 2017). Due to the
direct use of the narration structure and character
relationship of the original work, it is usually
recognized as constituting an adoption of the work's
protected expression under copyright doctrine, rather
than mere utilization of abstract ideas, and is more
likely to be recognized as infringing upon the
copyright of the original author without obtaining the
authorization of the original author (Wang, 2017).
2.2.2 Non-Deductive Fan Fiction
Such works usually only borrow the original
characters or background settings, creating new
content outside the original story framework, such as
the case of Jin Yong v. Jiangnan's “The Youth Here”.
2.3 Legal Dispute
The legal disputes over such works mainly focus on
whether the original virtual characters are protected.
The academic community generally believes that
simply using character names and basic personalities
usually does not constitute infringement, but if a
character possesses unique characteristics (such as
special styling, classic lines), it may be considered a
protected expression of originality (Wang, 2017). The
problem lies precisely in the lack of clear legal
provisions regarding the copyright of virtual
characters and the reasonable limits of using character
characteristics, which may result in completely
opposite judgments in similar cases in different
regions. This also leads creators to rely on industry
conventions for self-restraint, making it difficult to
have accurate legal standards to guide them.
In summary, there is a basic consensus in the
academic community on the issue of infringement in
deductive fan fiction. This article mainly analyzes the
infringement issues in non deductive fan fiction and
elaborates on them from different perspectives.
3 DETERMINATION OF
COPYRIGHT INFRINGEMENT
IN FAN FICTION
3.1 Copyright of the Character
The biggest characteristic of fan fiction is that it often
utilizes original characters for new text creation.
Therefore, whether the use of virtual characters in the
original work constitutes infringement, the first step
is to determine whether the characters themselves
have copyright. Although the Copyright Law of the
People's Republic of China (hereinafter referred to as
the “Copyright Law”) does not explicitly protect
certain roles, it does not exclude them from the scope
of protection. Therefore, a case-by-case analysis
should be conducted for specific situations.
For this issue, scholars often refer to the testing
methods used in American judicial practice, namely
the “sufficient description standard” and the “story
standard” as criteria for determining the copyright-
ability of characters: the former requires that such
virtual characters are originally conceived and
presented sufficiently, while the latter requires that
the virtual character be the core component of the
story and cannot be separated from it (Wang, 2025).
The application of two standards in practice is
controversial: sufficient description has strong
subjectivity, uncertainty, and is easily misinterpreted
in practice, even surpassing the binary framework of
thought and expression; The story standards are often
considered too strict, requiring infringing works to be
almost entirely descriptive of the character and not
exhaustive, and cannot classify the virtual
character itself as expression. Based on this, some
scholars further propose to distinguish between
character types, pointing out that stereotyped
characters should belong to the public domain due to
their lack of originality, while the use of original
characters that deeply integrate with the original plot
in fan works requires permission (Cong & Liu, 2021).
Copyright Infringement Issues in Fan Fiction
337
The first case of Chinese fan fiction, Jin Yong v.
Jiangnan, is a typical case regarding whether utilizing
original characters constitutes infringement. In the
first instance, the court held that the use of characters
did not constitute copyright infringement (China
Intellectual Property News, 2018). However, the
court of second instance considered that although it is
difficult to identify a single character as the object of
copyright protection, when the character gets a full
and unique description in the development of the plot,
it may be protected by the copyright law (Chinese
Copyright Association, 2023).
In a word, the essence of role infringement is the
overlapping use of original expression, rather than
simply exploiting names or accumulating images,
which mainly depends on whether the role forms an
“original personality” through specific expression. In
other words, the copyrightability of characters is
possible, but it still needs to be analyzed in detail from
the aspects of character, character relationship, and
specific plot development.
The problem is that the current law does not
explicitly provide for this, and the two standards
proposed by the judicial practice of the United States
are somewhat vague: The former does not specify the
“sufficient” quantitative scale, while the latter may
exclude most roles from the scope of protection, and
it is difficult to fully prove the copyright-ability of
roles. Therefore, although these two standards have
certain reference significance, they still need to rely
on the discretion of judges in case analysis. On this
premise, the author believes that the determination of
role infringement still needs to return to the
“dichotomy of thought expression”.
3.2 Dichotomy of Thought Expression
According to the second paragraph of Article 9 of the
TRIPS Agreement, the dichotomy of thought and
expression has always been the basic principle for
judicial practice to define copyright infringement,
which emphasizes that copyright law only protects
the original expression of ideas, not the ideas
themselves. When applied to the analysis of
infringement of fun fiction, it is necessary to define
which elements of the original work used by fun
fiction belong to the idea and which elements belong
to the original expression.
As mentioned above, generally speaking, the use
of the original elements in fun fiction is mainly to
borrow a series of elements such as names,
relationships and so on, which are extended with the
role as the core. The question is how to define
whether the use of the relevant role belongs to thought
or expression, which is also an argument for the
copyright of the role.
Some scholars believe that if the character
centered plot in the original work is substantially
used, such as the continuation of the work, the new
plot is based on the plot of the original work, which
constitutes infringement; If only the symbolic use of
a simple character, rather than the use of similar
circumstances, it does not constitute infringement
(Wang, 2017).
That is to say, the role name, basic character tag,
and general character relationship (such as master
apprentice) belong to the ideological category, which
allows free use and is not protected, while the plot
with the role as the core, the “original personality”
formed through the specific plot and interactive
mode, should belong to the expression category, such
as the character judgment in The Story of the Stone,
which integrates the original author's unique
expression and thought projection, and should be
protected.
Some scholars have cited the first instance verdict
of the case of Jin Yong v. Jiangnan as an example,
stating that “if fan fiction only uses static elements
such as the names and personalities of original
characters, and does not involve complex
relationships or personalized plots of characters, it is
difficult for copyright law to determine its
infringement behaviour (Hu & He et al, 2019).” This
determination is reasonable, but it ignores that the
static elements, such as the character's name and
character, should be analyzed in a unified way
according to the principle of integrity. The character's
name, character, relationship, background and so on
shape a role, reflecting the choice of the original
author, forming an original and logical structure,
which should be identified as expression, which is
also the basis for the second instance of this case.
To sum up, symbolic and labeled elements such
as character names, basic relationships, and simple
characters should belong to the ideological level,
allowing co-creators to freely use them. However, if
the characters form a unique fate track, interaction
mode, or similar experience due to the development
of the plot, it may constitute an original expression,
and if their use reaches a substantial similarity, it will
constitute infringement, which can be defined with
the help of the story standard mentioned above to a
certain extent.
On the basis of the dichotomy of thought and
expression, it is necessary to judge whether the
borrowing of the original expression is substantially
similar to analyze whether it constitutes an
ICPLSS 2025 - International Conference on Politics, Law, and Social Science
338
infringement of expression, which will be discussed
in detail below.
3.3 Contact Plus Substantial Similarity
The dichotomy of thought and expression analyzes
the objects protected by the Copyright Law, and the
principle of contact plus substantive similarity
analyzes and judges whether the use of the original
expression in the fun fiction of the same person meets
the infringement standard.
Since fun fictions are based on the original works,
it can be assumed that they have the possibility of
contact. Instead of analyzing the judgment basis, it is
only necessary to judge the substantial similarity
standard.
There are three main ways to judge whether a
substantial similarity is formed: first, the external
standard, that is, text comparison, verifies the
similarity through sentence-by-paragraph
comparison. Second, the internal standards, the
overall perception, and the reading of successive
works are based on the impression of general readers
on the two works. Third, abstract standards,
constantly abstract out the traditional ideas and
distinguish the unprotected parts (Zecevic, 2006).
Some scholars also mentioned that the description
of the role in the original work should be a
combination of complex and diverse text narration,
plot arrangement, character relationship and other
elements. Only in this way can the continuous
description of the role in the fun fiction of the same
person be substantially similar (Cong & Liu, 2021).
Similarly, when the description of the original
characters in the fun fiction composes a combined
description of the various complex expression
elements of the original characters, it may constitute
substantial similarity and constitute infringement.
The author believes that in the existing standards,
the mechanical text comparison is easy to ignore the
value of secondary creation, and there are also rigid
limitations. The originality of literary roles is
precisely derived from the superposition of details
such as name, character, and behavioral logic. When
the works of the same person continue the intrinsic
behavior pattern and destiny of the original
characters, even if the text is not copied directly, it
may still constitute infringement. Therefore, single
standard should be abandoned and make a
comprehensive judgment from the two levels of
overall perception and element analysis. From the
perspective of general readers, readers can read and
judge whether the whole work forms a substantial
similarity with the original work and then make a
quantitative comparison between the specific
elements (such as the originality of plot transition, the
similarity of complex human and material relations,
etc.) and the original work.
Based on the above three entry points for judging
infringement: the copyright of the role, the dichotomy
of thought and expression, and the contact and
substantive similarity, the author believes that to
judge whether a literary work of the same person
constitutes infringement, firstly should analyze
whether the original role used by the author is
copyrightable, and then refer to the cases of “full
description standard” and “story standard” to
specifically analyze whether the description of the
role in the original work by the author of the original
work constitutes an original expression, and then
judge whether it constitutes a copy of the expression
according to the dichotomy of thought and
expression, and finally judge whether it constitutes a
substantive similarity. If infringement is constituted,
then it should be judged next whether there is a
defense of fair use in the creation of the co-creator
based on the original work.
3.4 Fair Use Defense
The fair use rule of the Copyright Law of China
mainly adopts the three-step test method and lists the
relevant matters. Obviously, the use of original works
in fun fictions is difficult to directly cover the
provisions of the law, so it should be analyzed
through specific cases.
A number of scholars have suggested that the
application of the fair use system can refer to the four-
element standard of the United States, which
specifically includes: the purpose and nature of use,
the nature of the work used, the quantity and quality
of use, and the impact on the market. Some scholars
have pointed out that from the perspective of the
purpose and nature of use, if fan fictions have non-
profit and strong conversion, they can be more
recognized as fair use; At the level of market impact,
attention should be paid to whether fan fictions may
be exempted if they do not substantially replace the
original work market (Zecevic, 2006).
On this basis, many scholars put forward the
theory of “transformative use” which can be used for
reference in American judicial practice. The theory of
“transformative use” is the deepening development of
the element of “the purpose of using works” in the
four-element standard.
Some scholars believe that, based on analyzing
the particularity of using original virtual characters in
fan fiction, two very important points are whether the
Copyright Infringement Issues in Fan Fiction
339
purpose of using the work constitutes transformative
use and whether it has an impact on the potential
market or value of the original work (Cong & Liu,
2021). Some scholars have further proposed that
when secondary creative works are more
transformative, even if they have commercial
purposes, they can still constitute reasonable use
(Wang, 2006).
In terms of “transformative use”, it refers to
“adding new expression, meaning or information to
the original work for other purposes or different
properties to change the original work (Campbell v.
Acuff-Rose Music, 1990).” The birth of fan fiction is
based on fans' love for the original work, integrating
their own thoughts and expressions into the original
work, and reproducing the original work. The original
intention of fan fiction authors is not simply to imitate
or continue writing the original work, but to express
themselves through the original work and
communicate with other enthusiasts, which is a
manifestation of “transformative use”.
In terms of market alternatives, scholars generally
believe that this is the most important reason for the
reasonable use of fan works. Based on the unique
characteristics of their participatory culture, fan
literature creators not only do not have market
substitutability for the original work, but may even
promote the development of the original work in the
market in reverse. Therefore, it is generally not
considered to have a negative impact on the market or
value of the original work.
However, there is still some controversy
regarding the profitability of fan works. Although the
creation of fan works begins with the creator's love
for the original work, usually without commercial
purposes, and can be distinguished by readers, there
is also the possibility of seizing the market space of
the original work; Scholars usually advocate that non-
profit is more likely to constitute fair use (Sun & Li,
2020). However, with the development of the
Internet, a large number of works of colleagues in
reality make indirect profits through the network
platform, blurring the boundaries of “commerciality”.
It would be too harsh to deny the exemption of fair
use.
The author believes that on the basis of case
analysis, we should appropriately refer to the
"transformative use" theory, give priority to
evaluating the degree of conversion of the fun fiction,
such as whether to give new themes, introduce new
backgrounds, and give new role connotations, and
then analyze its market substitutability, review its
impact on the original derivative market, and avoid
excessive squeezing of the original creation space,
rather than simply determining whether it is profitable
to judge whether it constitutes a reasonable use.
4 CONCLUSION
With the vigorous development of Internet culture,
fun fictions, as a unique form of creation, not only
enriches cultural diversity, but also brings new
challenges to copyright law. This article reveals the
ambiguity and lag of the current legal framework in
addressing the issue of secondary creation by
analyzing the legal status, character copyright,
boundaries between ideas and expression, and
principles of fair use of fan fictions.
Although attempts have been made in judicial
practice to balance the interests of all parties through
individual discretion, the lack of unified legal
standards still leads to unclear boundaries of rights,
which may suppress creative enthusiasm and also
harm the legitimate rights and interests of the original
author. In the future, it is necessary to further clarify
the scope of copyright protection for virtual
characters at the legislative level, improve the
applicable standards of the fair use system, and
encourage the establishment of industry self-
discipline and diversified dispute resolution
mechanisms, in order to achieve a dynamic balance
between protecting originality and promoting
secondary creation, and provide a more inclusive
legal environment for cultural innovation in the
digital age.
