Abstract: Open-source software has emerged as a pivotal force driving technological innovation in the country. Its legal
foundation, the open-source license, is essential for ensuring the unimpeded circulation of software and pro-
tecting developers' rights. The prevalent use of GPL licenses, coupled with their highly infectious nature, has
given rise to legal controversies. In China's judicial practice, GPL violations often result in concurrent tort
and contract liabilities. While infringement claims better safeguard rights holders' interests, punitive damages
should be imposed judiciously. This article highlights that in GPL-licensed open-source software infringe-
ment disputes, the software's originality should not be disregarded due to illegal creation processes. Through
case analysis, legal doctrine examination, and comparative research, the article aims to bridge domestic re-
search gaps, integrate Chinese law with international experience, and propose improvements to balance cre-
ators' interests and foster the healthy development of open-source software.
1 INTRODUCTION
Open source software is a term used to describe
software that is open source. It is software that gives
users the right to copy, study, modify, and distribute
the software and makes the source code available for
free use (open source) with only minor other
restrictions. Linux and Firefox are examples of such
software. Open source software has its roots in the
code-sharing culture of the 1970s, where
commercialization and piracy led to stronger
protection under intellectual property laws, the launch
of the GNU ("GNU's Not Unix") project in 1983, and
the creation of the Free Software Foundation "FSF")
and the birth of the GPL (GNU General Public
License, abbreviated as "GPL License").
Subsequently, the BSD Unix system and the Linux
kernel further promoted the development of today's
open-source software has become a key driver of
technological innovation. With the popularity of
open-source technology in various industries,
international mainstream open-source licenses such
as Apache 2.0, MIT, BSD, GPL, etc. have been
widely used in China, but they have not been given
much attention in the legal field. The Outline of the
14th Five-Year Plan and 2035 Vision of the National
Economic and Social Development of the People's
Republic of China and the Outline of the Construction
of a Powerful Intellectual Property Rights Country
(2021-2035) all point out that "the intellectual
property rights of open source should be perfected
and the legal system should be improved", and at the
time the same, more and more copyright infringement
cases related to open source software have appeared
in China, including the case of, in which there are
more and more cases of copyright infringement. At
the same time, along with more and more cases of
copyright infringement on open-source software
appearing in China, the intellectual property issues
embedded therein have gradually surfaced and need
to be solved.
It is generally accepted in China that open-source
software is protected by copyright law and that GPL
licenses are contractual in nature. Therefore, in
judicial practice, illegal open source licenses may
involve two legal issues: one is the existence of open
source software developers and the licensee, the
licensee violated the open source license and arising
from the infringement of legal liability and
contractual legal liability of the competing issues; the
second is the open source software derivatives of the
infringement of copyright in the lawsuit whether to
violate the terms of the open source license to defend
the issue, for example, in the case of Nanjing Future
Co. v. Ltd. v. Zhejiang Yibang Communication
Technology Co., Ltd. and other disputes over
infringement of computer software copyright, while
the court of second instance held that the defendant's

non-infringement defense based on the GPL 2.0 could
not be upheld.
This paper takes GPL open source license as an
example to study its legal nature, legal liability and
defense in judicial practice and other related legal
issues of open source license in China, so as to make
the use of open source software more standardized,
and to make China's legislation on open source
software and judicial practice more sound in response
to promote the innovative development of open
source software and the improvement of the open
source software system in China.
2 VIOLATIONS OF
OPEN-SOURCE LICENSES ARE
MORE LIABLE TO
INFRINGEMENT OF THE LAW
Open source software licenses have evolved from
commercial and free software, allowing developers to
make source code publicly available for others to use
while maintaining intellectual property rights over the
source code. At the heart of this licensing mechanism
is the open-source license, which is granted by the
author and allows the user to perform certain acts that
would otherwise make it illegal to use the source code
of another person's software without
permission.(Zhao,2023)Open source licenses are not
only the legal basis of open source software, but also
the key to ensuring the free flow of software and
protecting the rights of developers. In this paper, we
will focus on the GPL license, which is different from
the relatively loose open-source licenses such as MIT,
BSD, Apache, etc. GPL license is one of the most
restrictive open source licenses, which is "highly
contagious" and must be open source. Anyone who
modifies or uses the software code under GPL
license, the modified version or derivative must be
open source, and when redistributing the source code,
the modified version or derivative must be open
source, and when redistributing the source code, the
modified version or derivative Anyone who
modifies or uses software code under a GPL license
must make the modified version or derivatives open
source, and redistribute the source code under a GPL
license without charging any license fees.
2.1 Competing Tort and Contractual
Liabilities for Breach of GPL
License
2.1.1 Legal Nature of The GPL License
In United States law, property law distinguishes
between a "contractual license" (Contractual license)
and a "unilateral license" (Bare license). A
"Contractual license" is an agreement between two
parties through offer, promise, and consideration, and
is regulated by contract law; a "Bare license" does not
require the consent of both parties, and the licensor
permits the licensee to do something not permitted by
law and is regulated by that law (in the case of the
GPL, by copyright law). In the case of GPL, the law
(i.e., copyright law) governs. Thus, in the United
States, there are views that GPL licenses are two-
party contracts for which contract law remedies may
be sought and views that GPL licenses are one-party
licenses for which copyright law remedies may be
sought.(Cheng,2023) Under China's legal system,
there is no dichotomy between contractual and
unilateral licenses, and therefore there is no such
controversy. Both in terms of doctrinal analysis and
judicial practice, GPL licenses can only be uniquely
interpreted as having contractual effect in China.
Although there are contrary views in the academic
circle that GPL has not gone through the two stages
of offer and promise in the traditional sense, and
therefore has not reached a consensus of intent, it
cannot be regarded as a contract.(Ma,2022) However,
according to the theory of offer and promise in civil
law contract law, even if there is no traditional
invitation and promise in the process of establishing
the agreement, it can be determined that the
agreement has been reached through the practical
behavior between the subjects. In GPL, the developer
uploads the code and the attached open-source license
to the public platform, which can be regarded as an
"offer"; if someone chooses to download the code,
even if he/she does not read the license, he/she can
still be regarded as accepting the constraints of the
license by virtue of the license statement attached to
the code, which can be regarded as a "promise". If
someone chooses to download the code, even without
reading the license statement, he can be considered to
have accepted to be bound by the license by virtue of
the license statement attached to the code, which can
be regarded as a "promise". There is no obstacle to .in
civil law jurisprudence interpreting the nature of open
source agreements as contracts.

159
China Jurisprudence from existing judicial
practice also supports this. In a case heard by the
Guangzhou Intellectual Property Court in 2021
concerning the dispute over the infringement of open
source software copyright in the case of Luo Box
Network Technology Co. v. Playmate Network
Technology Co. et al, the court of first instance held
that the licensor voluntarily granted most of the rights
of its copyright to an unspecified user by disclosing
the source code through the open source license in
accordance with the provisions of China's copyright
law; and that the user's copying, modification or
redistribution of the source code under the framework
of the license was also based on a voluntary
commitment to the license. Release the source code,
also based on a voluntary commitment to the license.
The license comes into effect when the user performs
these acts and is legally binding The GPL 3.0
agreement, as a copyright agreement of a contractual
nature, is regulated within the scope of China's
Contract Law (now the Contracts Section of the Civil
Code).((2019)Yue 73 ZhiMinChu 207 Hao)The
judgment clarifies that open source licenses are
contractual in nature and that open source licenses are
a form of contract chosen by the developer when
opening up the source code, which is regulated by the
Contracts Section of the Civil Code of China. It
protects the interests of the parties to the contract
through clear contractual rights and obligations,
which enhance the enforceability and protection of
the terms of the open-source license, as well as the
certainty and security of the transaction.
2.1.2 Competing Responsibilities
China The Copyright Law and the Regulations on the
Protection of Computer Software, as amended in
2021, stipulate that computer software is a copyright-
protected work and enjoys copyright rights such as
the right to publish, the right to attribute, the right to
modify, the right to reproduce, and the right to
distribute. Therefore, using software in violation of an
open-source license will infringe the copyright of the
software developer.
According to the above, the GPL open source
license is regarded as contractual in nature in China,
so the licensee can be held liable for breach of
contract if it violates the open source license, and then
there is a competition between tort liability and
breach of contract liability when the license is
violated. The parties may demand the licensee to bear
contractual liability for failure to comply with the
open source license or infringement liability for the
licensee's infringement of the licensor's copyright,
both of which are different in terms of the burden of
proof, as well as the standard of proof and the final
remedies.
2.2 Infringement claims for breach of
GPL open-source licenses are more
appropriate
2.2.1 The Application of Infringement
Claims Is More Conducive Times
Safeguarding The Legitimate Rights
and Interests of Open-Source Software
Owners
In terms of the form of liability, the liability for
breach of contract is generally divided into the
following: continuation of performance, remedial
measures, compensation for losses, liability for
liquidated damages, and liability for a deposit.
Liquidated damages and deposits are not involved in
open-source licenses, so only the first three types of
liability need to be discussed. Continued performance
and remedial action both imply that the licensee
continues to comply with the obligations of the open-
source license. The GUN General Public License
(GPL) v3.0 document published by the Free Software
Foundation states the licensee under the GPL
license's obligations: 1. pass on the same freedoms; 2.
protect the user's legal rights; 3. make the source code
available; 4. make modifications explicit; 5.
nonproprietary terms; 6. protect the user from
anticircumvention laws; 7. make the full counterpart
of the source code available; and 8. prohibit
sublicensing.(GNU,2007.) Therefore, when a
licensee breaches a license and needs to be ordered to
comply with the above obligations, it may involve
providing the source code, providing the complete
source code, requirements such as marking
modifications, etc., which are difficult to implement
and enforceable by the court. For example, if the
defendant is required to disclose the source code,
some of the source code may have already become
the defendant's trade secrets or undisclosed patented
technology programs, so it is difficult to require the
defendant to disclose it; if the defendant fails to
disclose it, it will involve the problem of enforcement
by the court, and the requirements such as "providing
the source code" and "marking the modification" are
not as important as property generally. Requirements
such as "provide source code", and "mark
modification" are not as good as the property can be
directly executed by the court, the court can only urge
the defendant to fulfill its obligations as soon as
possible, and the final performance effect is also
IESD 2025 - International Conference on Innovative Education and Social Development
160
uncertain, so it is difficult to achieve the relief, such a
situation is extremely unfavorable for the
maintenance of the plaintiff's rights.
Tort liability, on the other hand, is mainly divided
into cessation of infringement, elimination of
influence, apology, and compensation for damages.
Compared with the liability for breach of contract, the
defendant is ordered to fulfill the tort liability is more
achievable. Moreover, if the infringer constitutes
intentional and serious circumstances, the infringer
can also be punitive damages, although the judicial
practice has not appeared in the situation, at least
there is the possibility of increasing the amount of
compensation. According to the current judicial cases
can also be known, the damages of the tort claim are
much higher than the amount of compensation for
breach of contract, therefore, the plaintiff almost
always chooses the tort claim.(Zhao,2023) This
suggests that tort claims are more likely to protect the
owners' rights open source software than contract
claims.
In practice, the application of an infringement
claim presents the problem of the difficulty of
determining the amount of damages. The distribution
of open-source software essentially constitutes a
general license without license fees, which means that
it is difficult to quantify the actual loss or royalties of
the right holder when determining the amount of
compensation. Determining the amount of
compensation based on the infringer's proceeds of the
offense would require the infringer to provide
information on his or her profits. However, if the
infringer does not use the infringing software for
production or commercial operations, or is unwilling
to provide such information, the determination of the
amount of compensation is again difficult. In such
cases, it may ultimately be necessary to rely on
statutory damages provisions to determine the
amount of compensation. In judicial practice, it is
usually at the discretion of the judge to determine the
amount of damages to be awarded.(Chen,2023)
However, the remedy of tort is still relatively more
achievable and more conducive to the protection of
the licensor's rights than a claim for breach of
contract.
2.2.2 Extraterritorial Perspectives
Currently, the U.S. judicial practice has reached
basically a consensus, that is, open source software
rights holders can claim infringement of copyright
infringement and also can claim breach of contract. In
the United States judicial practice, in the early stage
of the development of open source software, the
United States court hearing open source software
cases, the right to copyright infringement of the cause
of action, and request for injunctive and damages
relief to support the claim. (Zhang,2004)However,
with the development of open source software, the
U.S. courts also believe that the violation of the GPL
open source license is a breach of contract, and does
not constitute copyright infringement, the copyright
infringement of injunctive relief filed by the right
holder of the lawsuit shall be rejected (Robert
JACOBSEN v. Matthew KATZER and Kamind
Associates, Inc, 535 F.3d 1373).With the
increasing number of open source software
infringement cases and the development of U.S. case
law, the courts now have a new solution to the idea
that, in the case of a software user's violation of an
open source license, the right holder can claim
injunctive relief for copyright infringement as well as
seek relief for breach of contract under contract law.
For example, in Jacobsen v. Katzer, the Court of
Appeals for the Federal Circuit held that the terms of
a license can constitute "copyright conditions" rather
than mere "contracts", and that both should be
recognized by law(2017 U.S. Dist, No. 16-CV-
06982-JSC).
However, FSF and its founder Richard Stallman
have always opposed the legal characterization of a
GPL license as a contract. The reason is that The
United States is a common law country that
distinguishes between state and federal law, with
contract law falling under state law and copyright law
falling under federal law. The contract law of each
state has some differences, if the GPL license is
qualified as a contract, or the breach of contract to
provide relief through the contract law, there will be
uncertainty in the process of defending the rights,
which may lead to inconsistency in the judicial
decision; moreover, the state law is lower than the
federal law, if the GPL license applies to the rules of
the contract law, the effect will be lower than the
federal law of the copyright law, which will not be
conducive to the achievement of the functional
purpose of the GPL license. Richard Stalman insisted
that software should not be privately owned, stressing
that society needs information that can be freely read,
modified, and enhanced, not closed "black box"
software. He argued that proprietary control by
software owners deprived users of their freedom and
limited their autonomy and that society should
encourage the spirit of volunteerism and mutual
assistance, rather than treating mutual assistance as
"piracy"(Stallman,2024). Therefore, he created a
strict GPL license to guarantee the continuation of
software freedom and open source. The relativity of
Chinese Law Perspective Study on the Legal Issues Related to the Violation of Open Source Licenses: Taking GPL as An Example
161
the contract makes the effect of the contract only to
the parties to the contract, and the third party other
than the parties to the contract can not enjoy the rights
in the contract and is not bound by the contract. In
order to ensure that the GPL license is binding on
everyone, not just the parties to the contract, the FSF
and Stallman hope that it can take advantage of the
exclusivity of the copyright, which is of universal
validity, and break through the limitations of the
relativity of the contract, so as to make the GPL
clause more solid under the U.S. law(Zhang,2022) so
as to truly realize the freedom of the open source
software, and to promote the development of its
development, which is in line with the concept of
"Freedom". The concept of "freedom" is fulfilled.
In our legal system, there is no distinction
between federal and state law, nor is there a
dichotomy between unilateral and contractual
licenses, so GPL licenses can only be interpreted as
contracts under our law. However, the designer of the
GPL did not intend the GPL to be a contract with
relativity but preferred it to have a worldwide effect.
Such a "universal validity" is also reflected in our
policy to a certain extent. The Outline of the
Fourteenth Five-Year Plan for National Economic
and Social Development and the Vision 2035 clearly
states that it supports the development of "open
source" digital technologies. Among them, "the
construction of open source algorithm platforms such
as deep learning frameworks" is included in the new
generation of artificial intelligence science and
technology frontiers, and "supporting the
development of digital technology open source
communities and other innovation consortiums,
perfecting the open source intellectual property rights
and legal system, and encouraging enterprises to open
up their software source codes, hardware designs, and
application services" is listed as one of the policies for
strengthening the development of digital technology.
Application services" is listed as an important
initiative to strengthen the application of key digital
technology innovation.The Outline for the
Construction of a Strong Intellectual Property
Country (2021-2035) also points out the need to
"improve open source intellectual property rights and
the legal system". It can be seen that China's policy is
centered on the development of "open source" and is
committed to accelerating the process of "open
source". In this process, compared with the protection
of open source software users, China is more inclined
to safeguard the rights and interests of open source
software and its licensors, aiming to promote the
prosperity and development of open source software
by strengthening the protection and improving the
protection system. Only by giving open source
licenses "universal validity" and making them
binding on all people can we protect open source
software more effectively and ensure that it receives
more comprehensive and strong protection. China's
practice in dealing with disputes related to the GPL
license should try to achieve the effect of the world.
Therefore, the application of infringement of GPL
license can be more in line with the original designer's
concept, and at the same time, if there is a dispute
involving extraterritorial open-source software, it can
also make China's justice in line with the international
standards.
Relatively speaking, the German legal system is
similar to ours. German courts are more uniform in
the characterization and attitude towards the violation
of open source licenses. German courts tend to regard
GPL open source licenses as contracts with
cancellation conditions, and when the licensee
violates the terms of the GPL license, the license is
considered invalid, i.e., the licensee's actions are not
licensed at that time, which constitutes an
infringement of rights, e.g., the cases of Welte v. D-
Link and Harald Welter v. SiteCom(Lv,2009). Thus,
German judicial practice tends to favor infringement
claims for breach of GPL licenses.
2.3 Claims for Infringement of
Open-Source Licenses Should Be
Strictly Limited times Punitive
Damages
It is worth noting that for GPL license violations, the
FSF's usual requirement is simply to correct and build
an enterprise-level GPL compliance program, rather
than pursuing the financial benefits of damages. The
FSF states in its Implementing the GNU GPL - The
GNU Project article that, while more stringent
measures are sometimes necessary, the Free Software
Foundation's goal has always been to ensure
compliance and to prevent future violations, rather
than pursuing damages or public admissions of
wrongdoing. "In nearly a decade of GPL
implementation, I have never insisted that a violator
pay damages to the Foundation for a violation, and I
have rarely asked a violator to publicly admit fault.
Our position has always been that ensuring
compliance and no further violations is the most
important goal. We try to make it as easy as possible
for the violator to be compliant, and we've always
been past the point of blame."Therefore, when
determining the amount of compensation, the court
should take into account the FSF's goal and
philosophy in creating the GPL license, should more
IESD 2025 - International Conference on Innovative Education and Social Development
162
strictly examine the high compensation claims and
determine the reasonable amount of compensation,
and be cautious in using punitive damages, otherwise,
it may result in the situation that some people
intentionally filed infringement lawsuits in order to
obtain a high amount of compensation, which makes
China's open-source software practice go against the
essence of the open-source software philosophy.
3 THE "OPEN SOURCE
DEFENCE " SHOULD NOT BE
UPHELD
In practice, there is also the issue of legal liability for
infringement of open-source software generated
under GPL licenses. Taking the GPL license as an
example, due to its "strong contagiousness", once the
software contains code under the GPL license,
subsequent works (including modified versions and
derivative works) created based on the software must
continue to be open-sourced under the GPL license.
Therefore, in practice, there may be cases where the
licensee has used the open source code with a GPL
license but has not complied with its open source
obligations, and the perpetrator is sued for
infringement of the above-mentioned software by the
software developer, but the perpetrator defends by
claiming that the plaintiff (the licensee) has failed to
disclose the source code in accordance with the
requirements of the GPL license, and the court should
not support such a defense. Simply put, the "open
source defense" is a defense raised by the defendant
in a software infringement case on the basis that the
plaintiff's right holder's software in question uses
open source code and is in breach of the open source
license.
In the case of Nanjing Future Company v. Jiangsu
Cloud Dragonfly Company and Others for
Infringement of Software Copyright (hereinafter
referred to as the "Future Case",((2021) Su 01
MinChu 3229 Hao)Future Company alleged that the
"Cloud Dragonfly Software - Bidding Document
Creator" released by Cloud Dragonfly Company was
highly similar to its software in terms of its functions
and realization, constituting an infringement of
copyright. The company alleged that the "Cloud
Dragonfly Software - Bidding Document Production
Tool" released by Cloud Dragonfly was highly
similar to its software in terms of function and
implementation, constituting infringement. Cloud
Dragonfly argued that the functions of the Cell
components in Future's software, such as SaveFile
and CloseFile, were developed by a third party, and
Future did not enjoy copyright in them. The Court of
First Instance upheld the open source defense,
holding that specific files in the source code of the
main program of the software involved in the case
were subject to the GPL agreement because they
contained the GPL (version 2.0) statement. Since the
preview program was not a derivative work of the
GPL open source code in question and was not
"infected" by the GPL code, it was not subject to the
GPL agreement. If it is found that the third party's
infringement of computer software is based on
Future's rights, it will essentially protect Future's
profits from its misconduct and give it an improper
legal status and special commercial advantage, which
is contrary to the legal principles of fairness and good
faith. In addition, providing tort protection to Future
in violation of the GPL agreement would hollow out
the GPL agreement's core provision of continuous
open source source code, negatively impacting the
GPL agreement's purpose of promoting open source
dissemination of source code.
Ltd. v. Zhejiang Yibang Communication
Technology Co., Ltd. and others for infringement of
computer software copyright disputes (hereinafter
referred to as the "Nethru case",((2021)
ZuiGaoFaZhiMinZhong 51 Hao) Nethru alleged that
Yibang and Qio had used the source code of
"OfficeTen" without authorization in similar
software. The two defendants argued that they had
used the source code of "OfficeTen" in similar
software without authorization. The two defendants
argued that "OfficeTen" was developed based on the
OpenWRT open-source software system, which
should comply with the GPLv2 agreement, and that
Nethru was obliged to disclose the source code of the
software in question. Therefore, the two defendants
claimed that their use of the software did not
constitute infringement of Nethru's copyright. The
Court of Second Instance held that the Defendants'
defense of non-infringement based on GPL 2.0 could
not be established because the case was a copyright
infringement dispute over the software in question,
not a contractual dispute; and it was difficult to
ascertain the facts relating to GPL 2.0 when the open
source software right holder was not a party to the
case. Even if it is assumed that the plaintiff violated
GPL 2.0, resulting in the existence of defective rights
of the software, the assumed defect does not affect the
plaintiff in this case to seek remedies for infringement
of copyright; whether the software developer violates
the GPL 2.0 and whether to enjoy the copyright of the
software, are two relatively independent issues of
law, and it is inappropriate to confuse them, so as to
Chinese Law Perspective Study on the Legal Issues Related to the Violation of Open Source Licenses: Taking GPL as An Example
163
avoid unreasonable deprivation or limitation of the
copyright of the software developer based on its
original contribution. The two issues should not be
confused, so as not to unreasonably deprive or restrict
software developers' copyright based on their original
contributions.
For the "open source defense", China's judicial
practice attitude is not consistent, most views do not
support the open source defense. According to
statistics, of the 11 cases of related disputes to date,
only one case of successful defense, two cases of
partial defense, one case of successful stage defense,
and seven cases of failed defense.(Xu,2024)
This paper argues, firstly, that the originality of an
author's creative process cannot be denied because of
the illegality of the process. Just as the court in the
NetWorks case held that whether the software
developer itself violates the GPL license and whether
it enjoys software copyright are two relatively
independent legal issues that should be viewed
separately and independently, the use of copyright
law to protect works created by right holders in
violation of the law is not in conflict with the fact that
the right holders should be held liable for violating
the obligations of the open source license. The scope
of protection of the generation modified or derived
from the original open source code by the copyright
law lies in the part which is original in relation to the
original open source code, rather than the part in the
original unauthorized open source code. The
protection of illegal deduction of software works is in
line with the basic mechanism of China's copyright
law to balance innovation and competition,
empowerment and restriction, protection and
dissemination, exclusivity and sharing, and to avoid
"over-protection" of the original work by copyright.
(Sun,2024)Moreover, the protection of the creation
and the original part of the creation is conducive to
stimulating public creativity.
Secondly, the court in the Future case held that
protecting the copyright of a right holder who
violated an open source license was an act "contrary
to the legal principles of fairness and good faith".
Here, the court cited basic principles of civil law as
theoretical support. However, it seems inappropriate
to use the principles of fairness and good faith directly
as the legal basis for the open-source defense. The
basic principles of civil law reflect the core attributes
of civil law, and as general norms of behavior and
standards of value, they are used in judicial practice
to interpret the law, supplement loopholes, and
correct evaluations. Nevertheless, the principles of
fairness and good faith do not specify the rights and
obligations of civil subjects, and judges are usually
not allowed to base their decisions directly on these
principles. Only when there is a loophole in our
copyright law or its specific application is contrary to
the basic value of civil law, it is allowed to invoke the
principle of fairness and good faith, in order to realize
the evaluation or amendment of the law.(Zhang,2024)
The "Future Case" is not in contradiction with the
basic value judgment of civil law, and as analyzed
above, the case reflects the protection mode of
"infringement to infringement, creation to creation"
in the judicial practice of copyright protection in
China.
Therefore, although the protection of the illegal
use of open source code generated by the generation
of a violation of the principle of fairness and good
faith, this is not in conflict with the protection of the
originality of the part. In dealing with the case of open
source software infringement, we should not only
consider the protection of the prior software
developers but also consider the protection of the
secondary creators in the future, balance their
interests, and promote the development of open
source software in China through the system path
suitable for our country.
4 CONCLUSION
Open source license is a crucial part of open source
software, which is not only the core of legal
protection, but also the key to ensuring the free
circulation of open source software and the rights and
interests of developers. At present, China's protection
of open source software and related things in the field
of copyright has not yet formed a complete
mechanism for the protection of the right holder, and
the rules of the path are not perfect, the right after the
damage to the relief is weak, the amount of damages
is difficult to determine, so all these shortcomings can
not effectively promote the sustainable development
of open source software. We should learn from
overseas mature experience, rooted in China's legal
soil, to explore a set of legislation suitable for China's
judicial system. Of course, in the development of
open source software and licenses, we should always
keep in mind the goals and concepts of its creation,
and combined with the understanding of China's
system, to provide theoretical support and practical
guidance for the legal protection of China's open
source software, in order to promote the healthy
development of open source software in China, and at
the same time to protect and stimulate technological
innovation.
