Executive Summary

IP activity in the area of RFID-based supply chain applications seems to have started in 1991, and peaked in 2004. Most of the action in the integration of electronic identification system (RFID) with software system in supply chain applications has taken place in the last ten years or so.

Around 423 patents have been published in the span of 4.2 years from 2000 till February 2005. The major market in RFID-based supply chain applications appears to be the United States.

RFID - Market Potential

• The global forecast RFID hardware, middleware, and IT market was worth $640 million in 2005. In 2006, this number will grow to more than $713 million, and is projected to reach more than $1.0 billion by 2011 at an average annual growth rate (AAGR) of 8.0%
  
• The RFID market is anticipated to continue to grow rapidly in these and many other market sectors and industries including the food and drug industry, propelled by United States FDA mandates. The technical issues that have made standardization more challenging are heading toward resolution with the emergence of the second-generation of UHF RFID.
  
• Retail RFID is estimated currently at just under 27% of the overall RFID market, and supply chain management (SCM) applications, when considered as separate from warehouse and distribution and transportation, represents just over 15% of the overall RFID market. These distributions will undoubtedly change rapidly, and should be reconsidered at regular time intervals as the RFID technology and established and emerging markets mature.

Introduction to RFID technology in supply chain

The supply chain is a complex multi-stage process which involves everything from the procurement of raw materials used to develop products, and their delivery to customers via warehouses and distribution centers. Supply chains exist in service, manufacturing and retail organizations.

Although, the complexity of the chain may vary greatly from industry to industry and firm to firm. Supply chain management can be seen as the supervision of information and finances of these materials, as they move through the different processes, by coordinating and integrating the flows within and among the different companies involved.

The efficiency of the supply chain has a direct impact on the profitability of a company. It is no surprise therefore to find that many large corporate companies have made it a key part of their strategy, and invested heavily in software systems (ERP, WMS...) and IT infrastructure designed to control inventory, track products and manage associated finance.

RFID will bring a new dimension to supply chain management by providing a more efficient way of being able to identify and track items at the various stages throughout the supply chain. It will allow product data to be captured automatically, and therefore be more quickly available for use by other processes such as ASN, stock management and real time billing.

Search approach and project scope

The first task was to find the relevant U.S. granted patents, and EP granted patents or published patent applications. This was done for all patents published in years 1975 to 2005. This range of years is more than sufficient; but almost all of the action has taken place in the last ten years or even considerably lesser time in some categories.

Identified patents in RFID-base supply chain applications category using a patent search filter. Filter development and testing is usually the most difficult and time-consuming part of a patent analysis, and that was certainly not the case in this research.

Patent search filters are sometimes relatively simple, but more often complex. Combinations of patent invention art classifications and keywords in titles, abstracts and claims were targeted for search. Because I was working with a combination of US and EP documents, I used classifications based on the International Patent Classification (IPC) system.

Details on the approach of search is given in search strategy. Since the scope of project is limited to test, therefore only 30 patent records were selected for quantitative analysis and 15 for qualitative analysis.

Most of the indicators could not be project due to insufficient data.

Objective:

The aim of this project is to identify IP activity in the area of RFID-Based supply chain applications primarily focused on the application of software in warehouse, distribution, inventory control and also the related applications.

Data Interpretation:

Appropriate patent records were selected for analysis. The selection criteria was based on:

• Type of RFID tags (Active, Passive, Microwave or Chipless)

• Type of receiver (Mobile, Handheld, fixed)

• Tag system (Read-only/WORM (Write once read many times)/Read-Write tags)

• Type of reader (Interrogator)

• Type Sensor and RFID frequency

• Receiver link and software

• Applications by where the event takes place (Airport, shipyard, factory, warehouse etc.)

• Process involved (Shipping, receiving, inventory etc.)

• Type of software used (Middle ware, applications etc.)

Search strategy:

Date of search: xyz

Database used: USPTO, EPO and PatFam

Keywords used for searching are listed below:

The total number of patent records on RFID based supply chain applications sourced through search was 212, but only 30 records were selected for analysis. An additional broad search conducted (database: PatFem) to understand the actual IP activity (based on keywords and assignees) as depicted in below tables:
