This document discusses patents related to wireless mobile devices. It begins by defining a patent as an invention that is new and useful, and defines a wireless mobile device as any device that transmits wirelessly for communication purposes. It then explains that patents protect intellectual capital and allow inventors to protect their inventions, avoid infringement, and leverage patents as business assets, especially in fast-growing industries. The document provides examples of patent areas for wireless mobile devices like software, electronics, transmission technologies, and discusses the evolution of cellular systems and wireless network technologies like Bluetooth, WiFi, and cellular networks. It concludes by stating that the efficiency and capacity of wireless information delivery has increased due to valuable patents, and that patents can be leveraged for profit

2. Patents for Wireless Mobile Devices
2
 What is a patent?

Invention that is new and useful
 What is an wireless mobile device?

Any device that transmits wirelessly for communication purposes

3. What does a Patent do?
3
 Patents protects intellectual capital for any technological
innovation.
 Businesses use patents as a business tool not only for
maintaining technology leadership but also for nurturing
economic growth.
 In a rapidly growing industries, intellectual property (IP)
can make the difference between survival and failure.

4. What does a Patent do? (Cont.)
4
Inventors and entrepreneurs need patents (and patent
laws) for:




protecting their inventions in the very early stages of product
development
determining the patentability of their invention
avoiding infringement of a competitor’s patent
and leveraging their patent as a business asset

5. Recognizing Intellectual Property
5
When viewing things within an IP framework, you…
 Recognize inventions
 Detect and avoid infringement
 Distinguish confidential information from general
knowledge
 Preserve confidentiality

6. Recognizing Intellectual Property

 Trademarks

Logos & symbols
 Copyrights


Right to reproduce an
idea or information
Includes software
 Patents

Invention that is new and useful
 Trade Secrets
 Non-disclosed information that is valuable

7. Wireless Mobile Device Patent Areas

10. What is Wireless Communication?
10
 Any form of communication that does not require the transmitter and
receiver to be in physical contact
 Electromagnetic wave propagated through free-space
 Radar, RF, Microwave, IR, Optical

11. Characteristics of Wireless Mobile Devices
11
Wireless
More Signal Processing
 Limited bandwidth, high latency
 Variable link
quality (noise, disconnections, other users)
 Heterogeneous air interfaces
Mobility:
More Protocol Processing
 User
and terminal location dynamically changes
 Speed of terminal mobility impacts wireless bandwidth
Portability
Higher Energy Efficiency
 Limited battery capacity, computing and storage
 Small dimensions

21. Summary
21
 A wireless mobile device depends on information delivered
by electromagnetic waves over various distances
 The efficiency and capacity of wireless information delivery
has increased as a result of hundreds of extremely valuable
patents
 A patent is legal protection of a new and useful invention;
beyond protecting new ideas, it can be leveraged for profit
 The size, functionality, and attractiveness of mobile devices
have also improved due to valuable patents

22. Next Week: Smartphone Patent War


Who’s suing who
Over what technology
And for what possible reasons
We will also discuss alternatives to litigation, such as
licensing IP
