Mark IV say TransCore violating patent by reading its transponders with E6 reader

May 20, 2009

Mark IV, manufacturers of E-ZPass transponders and readers for the E-ZPass Inter Agency Group (IAG) members claim that rivals TransCore are violating several of their patents on the Greenville Southern Connector. Mark IV cite an announcement March 31 that the Greenville SC tollroad is using TransCore's "Encompass 6" (E6) readers, and that these "support both IAG and SeGo protocols."

Mark IV in their statement say this "makes clear they have been using TransCore readers with Mark IV IVHS transponders on the Southern Connector Toll Road and in doing so violated three Mark IV IVHS patents."

Mark IV in effect are claiming that TransCore's E6 multiprotocol readers are an infringement of their patents because they can read their transponders.

The E6s are not in fact reading IAG transponders because the Southern Connector tollroad is not a member of the IAG, has no business arrangements in place to toll IAG transponders, or to receive payment from IAG members. However they are indisputably reading Mark IV transponders because from the beginning the Southern Connector has issued Mark IV transponders, and recently replaced Mark IV readers with TransCore E6 readers.

Mark IV is claiming, in effect, that no one may read one of their existing IAG protocol transponders with a reader manufactured by another party.

COMMENT: Mark IV officers won't comment but we don't understand how they can still claim patent rights to transponders and readers of a design that goes back to the early 1990s. They have received excellent compensation for their innovation from IAG members as a sole source uncompeted supplier since 1995.

The IAG needs to take a firm stand against Mark IV here. Mark IV's claim that any other reader that reads IAG transponders is an infringement of their patent rights is a direct challenge to the whole huge procurement of new toll technology and toll equipment underway at the IAG.

That's because any competitive bid in the procurement must offer equipment that can read existing Mark IV transponders for the inevitable transition of several years to new technology. There are about 25 million such transponders on the windshields of motor vehicles from Maine to West Virginia and from New Jersey to Illinois. You don't replace them overnight. Any new electronic toll system will have to comprise dual mode readers, with a Mark IV/IAG read capability as well as the new technology being adopted.

Mark IV is making a preposterous claim for a monopoly of electronic tolling with the IAG beyond the expiry of existing IAG contracts and beyond the normal patent protection period.

The IAG needs to stand clearly against Mark IV on this monopoly claim, and make clear it is  unacceptable. The IAG should state that TransCore, Kapsch, Sirit and any other bidders will be authorized by IAG, and supported with its considerable legal and financial resources to uphold the right of others to read Mark IV IAG transponders.

Otherwise IAG's current procurement is a farce and a fraud, and it is only going through the motions of a competition for new toll technology. Editor.

"MARK IV IVHS Notifies TransCore of Patent Infringements

"MISSISSAUGA, ONTARIO (May 20, 2009) - Mark IV Industries Corp (“MARK IV IVHS”), a global technology leader and innovator of intelligent transportation systems, today notified TransCore, a division of Roper Industries, that TransCore is violating several MARK IV IVHS patents and that TransCore must cease and desist all infringing activities.  TransCore has 30 days in which to enter into good faith negotiations with MARK IV IVHS in an effort to resolve this dispute.  If a resolution is not reached, MARK IV IVHS will file suit in U.S. District Court to enforce its intellectual property rights.

"TransCore’s announcement of March 31, 2009 made clear they have been using TransCore readers with MARK IV IVHS transponders on the Southern Connector Toll Road and in doing so violated three MARK IV IVHS patents.  MARK IV IVHS has no choice but to pursue legal action at this time to enforce MARK IV IVHS’ intellectual property rights and have the court stop this infringement and enjoin TransCore from committing any future infringement.

"The timing of TransCore’s announcement is likely not coincidental and almost certainly was done with the knowledge it would force the precise action now taken by MARK IV IVHS.  MARK IV IVHS will provide no further comments on this issue on the advice of legal counsel.


"MARK IV IVHS is a global technology leader and innovator of intelligent transportation systems (ITS).  With more than 18 million transponders on-the-road and more than 3,100 lanes equipped, MARK IV IVHS is the largest supplier of electronic toll collection equipment in North America.  MARK IV IVHS has enabled many landmark ITS deployments, including: the world’s first, non-stop, all-electronic toll road (Highway 407 ETR); interoperability between truck electronic preclearance systems and toll collection; and, the E-ZPass® system of the 25 toll authorities who comprise the Interagency Group in the Northeastern United States.  For more information, visit END Mark IV statement

TransCore Proves Alternative Equipment Choice for IAG-Protocol Reader

Provides Additional Path to Interoperability and Next Generation Wireless Toll Collection Technology

GREENVILLE, S.C.--(BUSINESS WIRE)--TransCore showcases Encompass® 6 IAG “Plug n Play” (PNP) radio frequency identification (RFID) reader system on The Southern Connector toll road, a 16-mile Federal interstate highway in Greenville, S.C., one of two toll roads in the state of South Carolina.

In use over the last 3 months, the Encompass 6 PNP reader, with an accuracy of 99.95 percent, has greatly reduced the violation rates at the lanes in which they are installed compared to lanes that operate with legacy equipment. The Encompass 6 PNP equipment configuration supports both IAG and SeGo protocols, a combination that offers compatibility with tags used in about 95 percent of all electronic toll collection lanes in the United States. The significance of the successful deployment is that Northeast toll authorities, which use IAG-only protocol hardware, now have multiple manufacturing sources.

“As the Southern Connector continues to provide a vital service to South Carolina motorists, we recognized the need to adopt technology that could meet our current capabilities without any reduction in service and provide a path to interoperability, particularly with other toll systems in the Southeast,” said Peter Femia, executive vice president and general manager of the Connector 2000 Association, Inc.

"The Southern Connector, which opened in 2001, was built with private money through a unique public-private partnership. No tax money was used for construction of the road. The Southern Connector is an important component of the development taking place in Southern Greenville County and provides an alternate route to many motorists and truckers seeking to avoid congestion on Interstate Highways 85 and 385. Following 8 years in operation, the Southern Connector has now processed more than 39 million toll transactions. The Connector 2000 Association is the governing body of the Southern Connector and has worked with TransCore since 2001 as the original systems integrator and current maintenance provider for the toll collection system

"After a vehicle collision at one of the toll plazas in 2008 required the replacement of equipment, the Southern Connector deployed the TransCore Plug n Play RFID readers as a direct replacement of the previous RFID hardware to read Palmetto Pass or “PalPass” transponders. Because of the plug and play design of the Encompass 6 reader, there was no need to perform any programming changes to transition to the next generation technology. Interoperability with current equipment and transponders was essential as was the potential for compatibility with electronic toll collection technology used throughout the Southeast from Georgia to Florida and west to Texas.
