Network Effects

Page 6: Intellectual Property Boston College Law School March 14, 2008 Software - Intro, Scope

Network Effects• Definition: where value of a product to one

consumer depends on number of other consumers using it

• Examples– Actual networks: e.g. telephone, fax machines,

instant messaging, etc.– Standards: e.g. QWERTY keyboard, MP3, etc.– Compatible products: e.g. VCRs, DVD, computer

operating systems, etc.

Page 7: Intellectual Property Boston College Law School March 14, 2008 Software - Intro, Scope

Costs and Benefits

• Benefits– Competing standards can be inefficient– Lower training costs, portability– Wider selection in complementary markets

• Costs– Lock in to suboptimal standard– Issues of market power where standard owned

to any idea, procedure, process, system, method of operation, concept, ….”

Page 10: Intellectual Property Boston College Law School March 14, 2008 Software - Intro, Scope

Issues

• Copyrightability– Object Code– Source Code– Non-Literal Structures– Functional Elements– Screen Displays– User Interfaces

Object Code

Page 12: Intellectual Property Boston College Law School March 14, 2008 Software - Intro, Scope

Whelan v. Jaslow• Dentalab v. Dentcom

– Different object code and source code– Similarities in non-literal elements

• File structures (how data stored)

• Screen outputs (how results displayed)

• Five subroutines– Order entry– Invoicing– Accounts receivable– End of day procedure– End of month procedure

Page 13: Intellectual Property Boston College Law School March 14, 2008 Software - Intro, Scope

Whelan v. Jaslow

• Standard for idea/expression:– “the purpose or function of a utilitarian work

would be the work’s idea, and everything that is not necessary to that purpose or function would be part of the expression of that idea.”

• Idea = purpose or function

• Expression = everything not necessary to purpose
