Derived Physical Property RightsJohn Locke - 2John Locke - 2ndnd Treatise of Government (1632-1704) Treatise of Government (1632-1704)
People have the right to property of their own person No one has the right to own another person People have the right to their own labor, and that labor should be to their own
benefit –nobody can hold slaves & labor for others is to be paid Right to anything removed from nature through their own labor –nobody
can snatch the gold you mined, except the state Note: from nature! Not from the neighbor’s back yard or employer’s office
Physical propertyPhysical property A person labors to cut down a tree in nature and chops it into pieces
Person also owns the chopped wood, if the person had right to tree possession Does not mean: OK to steal a tree; i.e. cut down a city or your neighbor’s tree
That person has exclusive rights to the chopped wood Unless she didn’t own the tree

Paradox Dealing with IPSimultaneous inventionsSimultaneous inventions
Intellectual property can be invented simultaneously! Can only give exclusive rights (e.g. patent) to one of them E.g. first production of aluminum in France and the US 1886: Two unknown young scientists, Paul Louis Toussaint Heroult (France)
and Charles Martin Hall (USA), working separately and unaware of each other's work, simultaneously invented a new electrolytic process, the Hall-Heroult process, which is the basis for all aluminium production today. They discovered that if they dissolved aluminium oxide (alumina) in a bath of molten cryolite and passed a powerful electric current through it, then molten aluminium would be deposited at the bottom of the bath
Differing notions of “stealing”Differing notions of “stealing” Intellectual property can be “stolen” without taking property away Some ideas can be copied against wish of the person having the initial ideas Only true way to prevent such copying is to keep the original idea
confidential

US Constitution“… promote the Progress of Science and useful Arts by securing
for limited Times to Authors and Inventors the exclusive Right to their respective Writings and Discoveries”
Allows persons to control distribution and use of their IPEncourages hard work and creativity by allowing inventor to reap
benefits from workRights are limited to a fixed period of time before entering public
domain
» Inventor must be rewarded so that innovation is encouraged
» Society must eventually benefit from the innovation

Trade SecretWell-kept secretWell-kept secret
Formulae, processes, proprietary designs, customer lists, strategic plans
Must take active steps to keep confidential Does not expire as long as kept confidential
Example: Coca Cola formula Example: Coca Cola formula Locked in a bank vault in Atlanta Merchandise 7X a secret for 100 years
Problems with trade secret:Problems with trade secret: Someone needs to work with the “secret” Reverse engineering is possible Employees leaving the company leave with the secret Can’t use it for things like movies (or even software) where public
display is necessary in order to obtain any benefit

TrademarkTM
Word, symbol, picture, sound, or color used by a business to identify Word, symbol, picture, sound, or color used by a business to identify goodsgoods Government grants the right to use it and the right to prevent other
companies from using it Allows a company to establish a “brand name” A Brand Name constitutes a real, tangible value, e.g. IBM™
Examples:Examples: Band-aid™, Xerox™, Intel™
Can become “commonized” resulting in loss of trademark rightCan become “commonized” resulting in loss of trademark right Aspirin, yo-yo, escalator, thermos Must always be used as an adjective to describe the brand rather than a
noun or a verb Adobe cracking down on the use of “Photoshopping” “I am stuck on Band-Aid brand” Kleenex brand facial tissue As adjective, cannot form plural, like a noun: e.g. Oreo Cookies, NOT Oreos!

Fair Use
Fair use – legal to reproduce copyrighted work without Fair use – legal to reproduce copyrighted work without permission of holder under certain conditionspermission of holder under certain conditions
US Copyright Act (CA)US Copyright Act (CA) does not specify what types of does not specify what types of copying constitute “fair use”copying constitute “fair use” courts rely on precedent, based on section 107 of CA
ExamplesExamples Citing short excerpts for teaching, scholarship, research,
criticism, commentary, and news reporting
15
Four Factors of Fair © UseSection 107 of the Copyright ActSection 107 of the Copyright Act
1. What is the purpose and character of the use? Educational versus commercial Educational uses are more permissible
2. What is the nature of the work being copied? Fiction versus non-fiction Published versus non-published Non-fiction is more likely permissible to be copied
3. How much of the copyrighted work is being used? Amount copied relative to total size of the work Easiest to determine!
4. How will this use affect the market for the copyrighted work? This point is THE heart of fair use, but hardest to measure
definitively
16
Copyright CasesKinkos (1991)Kinkos (1991)
“Professor publishing” practice Photocopying copyrighted materials for students Not fair-use even though purpose is educational
Full copy that impacts market of original significantly
MIT student making commercial software available freeMIT student making commercial software available free Charges dropped because the student did not profit,
rendering current law inapplicable Note inconsistency: “Professor publishing” did not benefit
professor No Electronic Theft Act (1997)
Closed this loopholeCriminal offense to reproduce or distribute more the $1000 worth
of copyrighted material in a 6 month period.

New Fair Use Restrictions
Exact copies are a bad thing… particularly digital!Exact copies are a bad thing… particularly digital! Technology radically increased the impact of copying A single copy *could* be easily distributed and affect the
commercial market of work
Audio Home Recording act of 1992Audio Home Recording act of 1992 Copies for personal and non-commercial use OK Royalty paid on the sale of recording devices and divided
among players Limited copying through smart card management systems
(SCMS) --prevents someone from copying a copy of a piece of work

RIAA vs. Diamond Multimedia Systems (1998)
Mid-90s saw advent of Mid-90s saw advent of mp3mp3 encoders and decoders encoders and decoders Rio mp3 player developed RIAA asked for injunction, preventing Rio sales, since it did
not include SCMS Rio was not a recording device, so it did not fall under Audio
Home Recording act of 1992 Software encoder on computer! Judgment also approved “space-shifting”
Copying in order to make portableFair use and consistent with copyright law

RIAA responseRIAA response Use fake accounts to poison downloads and track activity Targeted ISPs and universities to get user information
Sued Verizon to get real user information (success in June 2003) Started suing users who downloaded > 1000 files But, appeals court later ruled in Dec. 2003 that RIAA has no right to user
information from Verizon Sued individual universities to get student information Universities either started to ban P2P (PSU) or subscribe to legitimate
services (Napster)

Copyright Protection for Software
Software copyrightsSoftware copyrights Copyright act of 1976 explicitly recognized software Protects
Expression of idea – copyright implementation, not the idea Protects object code, not source code (typically the source code is
considered “confidential”. Exception: open-source software
Violations of software copyrightsViolations of software copyrights Not a violation:
Copying a program from CD-ROM to hard disk to run Copying a program from hard disk to RAM upon execution
Generally in violation if: Copying a program onto a CD to give/sell to someone else Preloading a program onto a computer being sold Distributing program over the Internet

Safe Software Development
General strategyGeneral strategy Clean-room development environment Two teams work on project
First team develops specifications of functionality based on working with the competitors products
Second team creates code based upon specifications
39
Open-Source vs. Proprietary SW
Proprietary softwareProprietary software Government gives rights to those who produce software
Benefit of profiting from licensing gives incentives for people to work hard, be creative, and eventually benefit society
Copyright protects the initial, tangible benefit Digital technology makes it trivial to copy and results in
harsh steps being taken
40
Open-SourceAlternative software development and distribution modelAlternative software development and distribution model
No restrictions on selling or even giving away the software For some licenses, source code must be published if modified and
distributed No restrictions on what to use for Rights apply to all who receive redistributions
BenefitsBenefits Anyone can improve the software Eliminates tension between obeying copyright law and helping
others --since code is given away Code is property of the community and lives indefinitely --no EOL Turns software into service industry rather than a manufacturing
one
41
Different Flavors
GPL v2GPL v2 Linux Vendor that distributes any code that uses GPL’d code must
publish all of their source code modifications as well
BSDBSD You may modify and redistribute without publishing the
source code
Other variantsOther variants Combination licenses
Free/GPL for non-commercial use, but commercial use requires a different license agreement
