Lawyers have their knives drawn in a patent dispute over the public domain 2D datamatrix technology. Originally invented by RVSI (now part of Siemens), the venerable datamatrix has been promoted as an open standard, is covered by ISO/IEC16022, and has been widely adopted as the symbology of choice by manufacturers due to its high data density, ease of marking, excellent error correction characteristics, and widely available scanners. Datamatrix is widely used on e-stamps (stamps.com), electricity bills, mailings, pharmaceuticals, UID, medical devices, auto parts, etc. etc.
Not so fast!, says Cognex - an industry leader in machine vision - who would have a lot to lose from its customers shying away from the 2D datamatrix. “We strongly object when questionable patents are used to extort payments from companies that do not have the expertise to challenge the patents, or who, for business reasons, decide to submit to licensing demands rather than to undertake costly legal challenges," said Dr. Robert J. Shillman, Cognex's Chairman and CEO. Cognex is well positioned – they beat the Lemelson case, and believe the patents being used by Acacia are far weaker.
