Freedom of expression

First Amendment

Professor Chiang of Antonin Scalia Law School argues that free speech is directly affected by patents。[1]

The existing literature on the interaction between intellectual property law and the First Amendment almost always operates with the explicit or implicit assumption that patent law has no free speech issues。This assumption is not only wrong but backwards。Far from being no threat to free speech,patent law poses a great to free speech than copyright law,both because patent protection is inherently stronger than copyright protection,and because patent law has developed none of the internal protections for free speech that copyright law has。

Judge主,主has opined against software patents on the premise that they violate the freedom of speech。[2][3]

Patents,which function as government-sanctioned monopolies,invade core First Amendment rights when they are allowed to obstruct the essential channels of scientific,economic,and political discourse。[…]Suppression of free speech is no less pernicious because it occurs in the digital,rather than the physical,realm。[…]Like all congressional powers,the power to issue patents and copyrights is circumscribed by the First Amendment。[…][R]estrictions on subject matter eligibility[should]be used to keep patection within constitutional bounds。ast of the First Amendment concerns associated with patent protection could be avoided if this court were willing to acknowledge that Alice sounded the death knell for software patents。[…]Given the vast number of software patents—most of which are replete with broad,functional claims—it is virtually impossible to innovate in any technological field without being ensnared by the patent thicket。

Paent advocates reacted vehemently to Mayer’s opinion,arguing that free speech is not absolute and that he misinterpretsAliceand other decisions of the美国Supreme Court[4][5]已安装的设备故障到address Mayer’s arguments on how分离,分离and the sheer number of software patents prohibit the software industry from writing code in practice。[6]Patent attorneys very frequently interpret the law in ways that allow them to defend a broken system。

ast modern communication systems are based on software。If only MyCompany can use a certain communication method,then anyone who can't afford the software of MyCompany,or anyone who objects to using the software of MyCompany is excluded from certain types of communication。

This article might provide an example:


If something is patented,then you might not be able to publish a sensible discussion about it(See for example Andrew Tridgell'sVFAT patch常见问题解答on LKML,the Linux Kernel Mailing List about avoidingMicrosoft's FAT patents

Sharing source code is an important part of understanding a program。Patents inhibit education by not allowing people to learn about software。



In,Ini4iv.Microsoftin the 2009USA,when微软lost,the judge noted that Microsoft was thereby prohibited from providing technical support for an aspect of their.docx format that is patented by i4i inc.“providing support or assistance to anyone that describes how to use any infringand Future Word Products to open an XML file containing custom XML“。[7]


As described in the 2008 amicus brief by theAmerican Civil Liberties Union[1]for the thein re Bilskicase,because“inducement to infringement“is a crime in theUSA,sharing technical information about a possibly-patented idea could lead to an infringement suit。

Source code may be speech

According to theSFLC[8]

First,source code,like the patent disclosures themselves,teaches how the invention works,rather than being the invention。If source code standing alone can infringe the patent,it is difficult to understand how handing out photocopies of the patent itself wouldn’t infringe。Second,in the US,courtsmayfind source code to be speech,as we believe they should find,thus making source code subject to First Amendment protection。[…Furthermore…]liability for patent infringement can be imposed where one enables or encourages another to infringe a patent,but the requirements of knowledge and intent are more strict in secondary liability situations。Because a user must first compile the source code and install the software in order to infringe,a court is less likely to hold the community liable for inducing or contributing to the infringement。
