Legal Aspects of Free SoftwareIntellectual Property
Free Software Licenses
The software license is a contract between the author of theprogram, and the final user. It states the rights granted by theauthor to the user, over the default rights (none) stated bythe IP laws.
Legally, the only difference between proprietary and freesoftware is the license.
There are several free software licenses. Although sometimeslook very similar, we should know the differences between“free” software licenses. These differences may severely affectto some basic rights of users over the software.
The property of the program never changes: the program isalways owned by the author. With the license, the user onlyget some rights of use.

Some concepts related with FLOSS licenses
Some concepts interesting for us:
Use: The right to use (run) the program, for any or somepurposes.
Redistribution: The act of copying the program and giving itto others.
Derivative work: A program based in other program, reusingits source code.
Authorship attribution: The obligation of recognizing theauthorship of a work when applying any change, such asderiving or redistributing it.
Juanjo Amor, Gregorio Robles Legal Issues of FLOSS
Legal Aspects of Free SoftwareIntellectual Property
The FLOSS definition
Free Software is the software that grant us four freedoms:
1 The freedom to run the program for any purpose, in anyplace, and forever.
2 The freedom of study and adapt it for our own needs.
3 The freedom to redistribute the work.
4 The freedom to improve the program and redistribute theseimprovements.
The Free Software licenses should guarantee these four freedoms.However, there are free software licenses more permissive and othermore strict (the most strict licenses are known as “copyleft”licenses).
Juanjo Amor, Gregorio Robles Legal Issues of FLOSS
Legal Aspects of Free SoftwareIntellectual Property
Free software licenses
Two main types:
1 Permissive licenses: “Minimalistic”, they grant modificationredistribution rights without requiring the same license.Examples: BSD, MIT, Apache.
2 Robust licenses: “Copyleft”, they grant modificationredistribution rights, but this can be done only under the samelicense. Examples: GPL, LGPL, IBMPL, MPL.
Please note that both license types are for “Free software”. Butwith the first type, you can do proprietary derivative works, andwith the copyleft license not.

Legal Aspects of Free SoftwareIntellectual Property
BSD Licenses
Origins:
BSD (Berkeley Software Distribution) is a Unix flavordeveloped by University of Berkeley (CA).
BSD Unix was licensed under a “minimalistic” license whichpermits both source or binary redistribution; alsomodifications, but without any other restriction.
The BSD licenses:
Based in original BSD license.
Very popular: X-Window, Tcl/Tk, etc.
You may redistribute the work, in any form (source or binary)but with all remaining copyright notes (authorshipattribution).
There is a “no warranty” clause. Very criticized, this clause isfor avoiding legal problems with the use of software and isalso very usual in proprietary software.

GNU GPL License
GPL = GNU General Public License.
GPL Concepts:
GPL = GNU General Public License.
Created by FSF for the GNU Project.
However, very often used in Free software non-GNU.
Probably, the most popular Free Software license: around70 % Freshmeat projects licensed under GPL.
Some popular software licensed under GPL: Linux, GNOME,Emacs, GCC, Epiphany. . .
Juanjo Amor, Gregorio Robles Legal Issues of FLOSS
Legal Aspects of Free SoftwareIntellectual Property
GNU GPL License (II)
GPL Characteristics:
This license guarantees the four FLOSS freedoms.
It is though to always guarantee code freedom. This is themeaning of the “copyleft” clause: all derivative works shouldbe licensed also under the same license.
Since in USA software patents are possible, GPL includes aclause for avoiding GPL licensing of patented software oralgorithms.
GPL has three versions. The most known is GPL Version 2because has been on the market for more than 10 years.However, in 2006 the GPL V3 born.
GPL code can not be mixed with other code under“GPL-incompatible” license.
Juanjo Amor, Gregorio Robles Legal Issues of FLOSS
Legal Aspects of Free SoftwareIntellectual Property
GNU LGPL License
LGPL = Lesser GPL
LGPL started as “Library GPL”. Later renamed to “LesserGPL”.
LGPL maintain all freedoms and restrictions to the licensedsoftware, but with one exception:
LGPL Software can be integrated with any other software,without limitations (including proprietary).
Why LGPL?
Created for promoting the use of GPL libraries in any othersoftware (ex: GNU libc).
Later, FSF checked that LGPL did not helped to the creationof new Free software, so they decided to rename it to “lesser”and discourage its use.
Juanjo Amor, Gregorio Robles Legal Issues of FLOSS
Legal Aspects of Free SoftwareIntellectual Property
Other permissive licenses
X-Window R11 License (X11). This license applies to the mostused graphical subsystem in Unix systems. The license is very similarto BSD and is also known as “MIT license”. Some other derivativeworks are licensed under X11 License, such as XFree86.
Zope Public License 2.0. This license is used by the Zopedistribution (an application server) and some related products. NearBSD license, also prohibits the use of Zope Corporation trademarks.
Apache. Very similar to BSD, lies in the license used by almost allApache project products.
Public domain. An intellectual work in the public domain is neitherunder any IP law nor a license. Most public domain works retains,however, the authorship. For this reason, it is very similar to havethe program under PD or under a BSD license.
Juanjo Amor, Gregorio Robles Legal Issues of FLOSS
Legal Aspects of Free SoftwareIntellectual Property
Other robust licenses
Sleepycat. This license is used, for example, in Berkeley DB. Verysimilar to GPL (including copyleft clause), although shorter.
eCos. It is used in eCos, a real-time OS. It is a GPL modification, inorder to avoid the restriction of integration between GPL softwareand GPL-incompatible software. In fact, it is a LGPL.
Affero GPL. It is though for programs which do web service. Itincludes a clause for mandatory maintaining the web redistributionof source code, if the author wanted it.
IBM Public License 1.0. This license, similar to GPL, also includesthe obligation of a free licensing of any patents used in any latermodification.
Mozilla PL 1.1. It is a robust FLOSS license created by MozillaFoundation when decided to release the first FLOSS version of theirnavigator, based in old Netscape code.
Juanjo Amor, Gregorio Robles Legal Issues of FLOSS
Legal Aspects of Free SoftwareIntellectual Property
Dual Licensing
An author can distribute his work under more than one license.
Sometimes, the author releases a version which differs withthe previous only in the license.
For example, the case of Staroffice and OpenOffice.
Since the author is the owner of the program, he can alwaysselect the license of his program; for example, he can changefrom a free license to a proprietary one. However, the versionwith free license will ever exists and the conditions for thisversion will not change.
Juanjo Amor, Gregorio Robles Legal Issues of FLOSS
Legal Aspects of Free SoftwareIntellectual Property
“Free” Licenses for other intellectual works
FLOSS licenses have inspired licenses for other intellectualworks: audio, video, . . .
For example, GNU has the “Free Documentation License”. Inthis license:
There are distinction between “transparent” copies of thedocument (similar to “source”) and “opaque” copies (similarto “binary”).There are some additional restrictions: acknowledgments,dedications, and the history of the document can be modifiedbut only by adding new lines.The book could include “invariant” and “cover” sections, notmodifiable. However, only “non-technical” texts can beconsidered invariant.GFDL does not comply with Debian guidelines. For thisreason, Debian requests that the documentation is publisheddirectly under GPL.

Legal Aspects of Free SoftwareIntellectual Property
Creative Commons objectives
Creative Commons, a non-profit organisation for...
Creating a set of licenses, for any type of content.
Indexing CC licensed works, so you can locate free contentsfast...
International adaptation of licenses (for example, there areSpanish official CC licenses)
http://www.creativecommons.org/

Legal Aspects of Free SoftwareIntellectual Property
Creative Common Licenses objectives
With Creative Common licenses you can...
Donate your work to the public domain or...
Maintain some rights:
AttributionNon-commercialNo derivativeShare Alike
You can combine these rights (with some logical exceptions).So, you maintain
some rights reserved.
Juanjo Amor, Gregorio Robles Legal Issues of FLOSS

Combining rights
There are eleven possible combination of rights.
If you don’t retain any of these rights, you are donating yourwork to the public domain.
So, there are eleven Creative Commons licenses.
11, not 16 licenses! Why?
Juanjo Amor, Gregorio Robles Legal Issues of FLOSS

The eleven licenses
Attribution

Juanjo Amor, Gregorio Robles Legal Issues of FLOSS
Legal Aspects of Free SoftwareIntellectual Property
The Attribution-ShareAlike license
With this license, you reserve two rights:
Attribution of your work.
Any derived work must be licensed under same license.
There are not restrictions in commercial use or derivative works.So, this license is the nearest to a FLOSS license. However, thereare some problems. . .
Juanjo Amor, Gregorio Robles Legal Issues of FLOSS
Legal Aspects of Free SoftwareIntellectual Property
Debian-legal enters the arena
After the popularization of CC, Debian-legal entered and warned ofAttribution. The causes were:
A work under Attribution can be in fact, NoDerivs.
Inaccurate or excessive authorship credits.
Problems with Anti-DRM clause.
Trademark restrictions.
Attribution[-ShareAlike] is notcompatible with DFSG
Juanjo Amor, Gregorio Robles Legal Issues of FLOSS
Legal Aspects of Free SoftwareIntellectual Property
Attribution Problems (I)
Licensor/Original Author can request removal of him/herreferences in derived works.
However the author name must be included in derivativeworks “if supplied” (Attribution)
It’s unclear if creator of derivative works can comply with arequirement of removing references and requirement of giveattribution. Then, a request to remove references can makeimpossible to comply with Attribution; so it may not be possible tomake derivative/collective works under this license (DFSG 3 & 1incompatible). The work is not free?
Juanjo Amor, Gregorio Robles Legal Issues of FLOSS
Legal Aspects of Free SoftwareIntellectual Property
Attribution Problems (II): Authorship credits
Requirements for crediting Licensor for his/her work: it’sambiguous
So, we need the most pessimistic interpretation:
Required attribution for the licensor everywhere thatauthorship credit is given.
Example 1: If a work is a collection of essays by different authors,with authorship credit given in the chapter titles, the Licensor’sname would have to be listed for each chapter title, even if theydid not contribute to it.Example 2: If Alice writes her autobiography, and includes lyricsfrom Bob’s song in one chapter, she must give him credit for theentire work: “The Autobiography of Alice, by Alice and Bob”, oreven “The Autobiography of Alice and Bob.”
Juanjo Amor, Gregorio Robles Legal Issues of FLOSS
Legal Aspects of Free SoftwareIntellectual Property
Attribution Problems (III)
Anti-DRM Clause: Distribution with measures to controlaccess is not compatible with DFSG 1.
Example 1: Private distribution of work might be forbidden.Example 2: Distribution in a server with control access (i.e.firewall) might be forbidden.
Juanjo Amor, Gregorio Robles Legal Issues of FLOSS
Legal Aspects of Free SoftwareIntellectual Property
Attribution Problems (IV)
Web page says: Using CC trademark or logos is strictlyprohibited when it’s used for other than indicating the work islicensed under CC.
Altough CC Trademark not appears to be part of the CClicenses, this is only warned in “source code” of CC web page.
Interpretation: This can prevent redistribution, modification ...
Juanjo Amor, Gregorio Robles Legal Issues of FLOSS
Legal Aspects of Free SoftwareIntellectual Property
NoDerivs problems
Obviously, NoDerivs licenses are not
compatible with Four Freedoms (nor DFSG)
Juanjo Amor, Gregorio Robles Legal Issues of FLOSS

NonCommercial problems
Obviously, NonCommercial licenses are not

Juanjo Amor, Gregorio Robles Legal Issues of FLOSS
Legal Aspects of Free SoftwareIntellectual Property
Debian recommends to authors...
All software licensed under CC is not compatible with DFSG.
Software licensed under NonCommercial/NoDerivs cannot benamed “Free Software”
Authors who wish to use Attribution must use other licensesas BSD.
Authors who wish to use Attribution-ShareAlike must useother licenses as GPL.
Juanjo Amor, Gregorio Robles Legal Issues of FLOSS
Legal Aspects of Free SoftwareIntellectual Property
Debian recommends to leaders of CreativeCommons...
Limit scope of request to remove references.
Waive attribution after request to remove references.
Allow access-controlled private distribution.
Allow distribution of rights-restricted copies of works ifunrestricted copies are also made available.
Require “credit for comparable authorship”.
Specify “other credit”.

Intellectual Property (IP)
Juanjo Amor, Gregorio Robles Legal Issues of FLOSS
Legal Aspects of Free SoftwareIntellectual Property
IP: Introduction
Author’s rights
The type of works considered include: literature works (novels,poems, theater works, reference documents, newspapers andsoftwrae), artistic works, scientific works, databases, movies,musical compositions and choreographies, architectonic works,publicity, maps and technical paintings.The protection is given to the form, the continent, theexpression of the creative idea, but not on its contents.Neither the material for inspiraction (facts, dates...) nor theideas are protected.In software the expression is given by the code; algorithms arenot protected.Neighboring rights: Paganini’s music may be performed byanybody as it is a work in the public domain. But artists andproducers related to a CD of Paganini may have rights ontheir performance.
Differences between the Anglo-Saxon legal (where IP groupseverything) and the Continental (where IP and Industrial Propertyexist) system.WIPO gives an “Anglo-Saxon” definition of IP, but anapproximation:
Intellectual property refers to creations of the mind:inventions, literary and artistic works, and symbols, names,images, and designs used in commerce.
Juanjo Amor, Gregorio Robles Legal Issues of FLOSS
Legal Aspects of Free SoftwareIntellectual Property
Origins
With the invention of the press, works became commercial objects.First forms of plaguiarism appeared, so that editors forcedlegislators to regulate and protect the original works.Regulation was also conceived as a way of controlling information(i.e. censorship)
Juanjo Amor, Gregorio Robles Legal Issues of FLOSS
Legal Aspects of Free SoftwareIntellectual Property
Copyright on software (I)
Software came first as part of a hardware system (bundling)The necessity of copyright began to arise when IBM had to split itsbusiness due to anti-monopoly legislation in the U.S.: softwarebegan to be distributed in an independent mannerThe goals of the copyright where:
Protect investments in the development
Promote de distribution of works
Protect the creative human activity by providing incentives
Protect a technology very prone to be copied
At first, there was a big debate about if software should beprotected by patents or by copyright.
Juanjo Amor, Gregorio Robles Legal Issues of FLOSS
Legal Aspects of Free SoftwareIntellectual Property
Copyright on software (II)
Copyright was finally chosen because of following characteristics:
Simplicity (no registration, no formalities...)
Automatic
Inexpensive
No novelty, just originality (it may be state of the art!).Authors’ right: personal and not trivial. Copyright: justpersonal.
Includes documentation
International (several conventions on copyright)
Armonization with other works
Adapting the concept of copyright to software is not an easy taskas there are many exceptions and special circumstances.
Juanjo Amor, Gregorio Robles Legal Issues of FLOSS
Legal Aspects of Free SoftwareIntellectual Property
IP: Concepts
IP: refers to several issues, depending on its context.
Today, very often used referring to the privileges ofnon-physical goods with economic value.
Examples (Anglo-Saxon system):
Copyrights: Protect from unauthorized copy: artistic or literaryworks, computer programs, data collections, industrial designs,etc.
Trademarks: Protect company symbols and names.
Trade secrets: Protect access to some industrial secrets.
Patents: Protect the rights of exploiting inventions.
Sometimes (for instance, in the Continental legal system):
Intellectual Property: only for copyright issues.
Industrial Property: rest of issues.
Juanjo Amor, Gregorio Robles Legal Issues of FLOSS
Legal Aspects of Free SoftwareIntellectual Property
Copyright on software (and III)
What in software falls under copyright:
The computer program (i.e. instructions, in any form): sourcecode and object code!
The description of the program (for instance, its UML)
Additional material (user manuals, guides, etc.)
Interfaces (graphics, sound, typographies...)
Databases
Juanjo Amor, Gregorio Robles Legal Issues of FLOSS
Legal Aspects of Free SoftwareIntellectual Property
Authors and copyright holders
Authors is a (physical or juridical) person that creates a work.
Collaborative work: unitary result of the collaboration ofseveral authors where the input of each author may beidentified and exploit independently.
Collective work: under the initiative and coordination of aphysical or juridical person. It groups the input of severalauthors that cannot be identified independently and thatcompose a unique and autonomous creation. Examples:GNOME, Mozilla, FSF, etc.
The work produced by an empolyee or by means of a contractis owned by the company. But the moral rights are stillretained by the programmer.
Juanjo Amor, Gregorio Robles Legal Issues of FLOSS
Legal Aspects of Free SoftwareIntellectual Property
The Copyright: Protection for Authors
The rights protected by copyright laws:
Moral rights. Guarantee work dissemination and authorattribution. Only in Continental law.
Exploitation rights. Guarantee economic exploitation.
Exploitation rights have time expiration, depending on local laws.For example, in Spain they expire 70 years after the author’s death.
How can we grant some rights to users of copyrighted works?
Juanjo Amor, Gregorio Robles Legal Issues of FLOSS
Legal Aspects of Free SoftwareIntellectual Property
Moral rights
Disclosure of the work
Way of publication: with his name, a pseudonym or anonym
Recognition of his name and respect to his authors’ status
The right of the integrity of his work
The modification of his work
The withdrawal of his work (addressing compensation ifneeded)
To access a unique exemplar if in possession of any otherperson
These rights cannot be withdrawn, cannot be transfered, areinalienable and some even perpetual.
Juanjo Amor, Gregorio Robles Legal Issues of FLOSS
Legal Aspects of Free SoftwareIntellectual Property
Exploitation rights
(really exploitation and compensation rights)
Reproduction (includes communication and copying): loading,presentation on the screen, execution, transmission andstorage.
Even for using a program you require the author’s aproval!The right to copy/reproduce is fundamental in licenses; elsethe software cannot be run.If somebody steals a book, he is attempting against the ownerof the book but not the owner of the IP. If you copy a softwarewithout authorization, you are attempting against the owner ofthe IP as you need his approval to reproduce (copy) it.
Distribution: Public disposal of physical copies (i.e. offeringthe software over the Internet is not included). Software is notsold as this could make re-selling possible. What is sold is theCD; the software is licensed!Public performance (there is no distribution of physical copies;it is known as the right to make it available). What is publicand private on the Internet?Transformation (for instance, translation)
Juanjo Amor, Gregorio Robles Legal Issues of FLOSS
Legal Aspects of Free SoftwareIntellectual Property
Licenses: Concepts
License:
A contract between the author and the user.
Grants some rights to the users of copyrighted work.
You don’t need to sign the contract, but in that case, you don’thave any rights over the copyrighted work. That is, if you do notaccept the license, you cannot use the work.
Juanjo Amor, Gregorio Robles Legal Issues of FLOSS
Legal Aspects of Free SoftwareIntellectual Property
The copy problem
Today, to make a copy of a intellectual work is very easy:
Books: You can photocopy (or manually copy) it.
Music, Video, Software: You can copy it without quality loss.
Copy costs are very low, nearly zero.
Most IP laws and the Spanish one (LPI, 2006) state that:
“Private copies” of music, etc, are always legal.
In the case of software, you can do copies for backups. Also,you should access the contents in order to make compatibleprograms, adapt it for your needs, etc.
Usually, these rights for the software are not applicable, since wedon’t have the source code.Although licenses should no restrict these rights, recent lawmodifications apparently tend to remove our rights.
Juanjo Amor, Gregorio Robles Legal Issues of FLOSS
Legal Aspects of Free SoftwareIntellectual Property
The copy problem: Internet
With the Computer, Digital Age and Internet:
To copy intellectual works is easier.
Not only software: but music, videos, etc.
Without quality loss.
Also, Internet helps to the fast dissemination of copies. But it’sdifficult to know when the copy is “legally done” and when not.Example (Music):
I can access to “private” copies of my music on Internet. I canbuy the “original” CD and access to copies through Emule. Isthis illegal?
Several controversies about the question: “To share my musicis legal or not?”.
Juanjo Amor, Gregorio Robles Legal Issues of FLOSS
Legal Aspects of Free SoftwareIntellectual Property
The Piracy
With computers and Internet, the illegal copies received a name:
“Piracy”
Several organizations fight the “piracy”. Example:
Business Software Alliance (BSA).
This is a controversial word because it means “act of robbery overhigh seas” (with violence).
Juanjo Amor, Gregorio Robles Legal Issues of FLOSS
Legal Aspects of Free SoftwareIntellectual Property
Trade secrets
A trade secret is a way to protect investments in industrialarea, through Industrial Property laws.
Under trade secrets, there are several goods such as chemicalor pharmaceutical formulas, but also software.
Proprietary software enterprises hide the source code of theirsoftware products as a way to protect their investment increating such software.
One of the objectives, for example, is to avoid the creation ofderivative works.
However, in some countries, reverse engineering is permittedin order to create compatible software products.
Juanjo Amor, Gregorio Robles Legal Issues of FLOSS
Legal Aspects of Free SoftwareIntellectual Property
Patents
Patents?
The invention is not protected by secret. On the contrary, theinvention is publicly available.However, for a certain period (from 17 to 25 years) forexploiting the invention the interested company must pay alicense.
From other point of view, the patent is not a right to use theinvention, but provides the right to exclude others frommaking, using, selling, offering for sale, or importing thepatented; for the signed period.
Patents, good or bad?
Promoting the innovation.The abuses: how to stop the innovation.The software patents.
Juanjo Amor, Gregorio Robles Legal Issues of FLOSS
Legal Aspects of Free SoftwareIntellectual Property
Utility models
Utility Model:
Intellectual property right to protect inventions.
This right is available in some countries, such as Spain.
Characteristics:
Similar to the patent.
Less duration. From 6 to 10 years.
Less stringent patentability requirements.
For us, an utility model should be viewed very similar to a patent,except for the requirements and duration.
Juanjo Amor, Gregorio Robles Legal Issues of FLOSS
Legal Aspects of Free SoftwareIntellectual Property
Software patents
Some comments about software patents:
In some countries they are not legal.
For example, Europe does not accept software patents, but inUSA.
Although not legal, in practice, lots of algorithms, and in fact,ideas, have been patented.
Since trivial ideas (implemented with algorithms) arepatented, they are often used by owners to drown competitors.
“Patent trolls”: Companies with a “patent portfolio”, whichsues other competitors for infringement of patents while doinglittle to really innovate.
It is very easy to infringe a lot of patents when developing asoftware project.
Juanjo Amor, Gregorio Robles Legal Issues of FLOSS
Legal Aspects of Free SoftwareIntellectual Property
Trademarks
A trade name, is the name which a business trades under forcommercial purposes, although its registered, legal name, usedfor contracts and other formal situations, may be another.
Trading names are sometimes registered as trademarks or areregarded as brands.
In Free Software, there are not very important, probablybecause registering a trademark is not free and mostdevelopers do not pay attention on them. However, there aresome well known trademarks in this world, such as GNOME,GNU, Debian.
Sometimes, the names are not registered in most countriesand this implied some problems. For example, in USAsomebody registered the trademark “Linux” and tried toobtain money for its use.
