Abstract
RFID (Radio Frequency Identification) RFID market - US$92 million ( 2003) - US$1.3 billion ( 2008) Database - USPTO Analysis Tool – Patent Guider Research Motive – With systematic tools, it can help ex
plore tens of thousands of patent documents in details to produce patent information for data mining and analysis by experts in order to turn the information into knowledge of business values.

1. Definition and Application of RFID
Accenture(2001) : RFID is a technology which enables electronic
tags and the item identification system to communicate through radio frequency. It is a technology free from spatial limits and capable of faster data exchange, item tracking, categorization, statistics, analysis and acquisition of related data.
2. Difference between RFID Tags and Traditional Bar Codes
The major difference between bar coding and RFID lies in the fact that RFID can automatically read 250 tags per second, contain more data and monitor inventory in real time. Compared with the bar coding currently in use, RFID can automate product registration, significantly reducing labor costs and enhancing operation efficiency.

Conclusions
RFID is being widely applied in the industries ; the future development of RFID is expected to move
toward identification of smaller items and smarter tags; The company should adopt a patent application strategy
that focuses on quality and quantity to supplement its technological insufficiency and to prevent its competitors from entering the market through design-around schemes.
The End!
