Research Motive


With systematic tools, it can help
explore 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.

4. Introduction to Patent Analysis


One of the most effective methods to keep in
touch with technology innovations;


A tool to find out the connection between
technology development and economic growth;


To help understand the processes of technology
innovations by local and international enterprises.


5. RFID Patent Mapping Analysis


Patent mapping can provide technology
developers and enterprise managers clear and
comprehensive guidelines. Patent mapping can
provide technology developers and enterprise
managers clear and comprehensive guidelines.

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.
