Yesterday at the Dealer Expo 2007 in Indianapolis U.S. Marshals served papers on about half a dozen exhibitors who allegedly manufactured unauthorized copies of patent-protected products. Manufacturers who claimed the exhibitors had violated intellectual property laws filed the lawsuits. Additional lawsuits may be served today. Advanstar sends letters to companies accused of copying products, notifying them that their future participation in the Expo could be denied if they are held liable for the offense. "It’s an understandable concern of our exhibitors," said Tracy Harris, vice president with show owner Advanstar, "but we’re not the police." Contingent of lawyers are walking the floor looking for exhibitors who might be selling illegal copies of manufacturers products. I have had quite a few illegal copies of my parts produced here in the US and China. So, I can only approve what’s happening this weekend in Indianapolis. For information I just wrote a piece to be published in Barnett Magazine about knock-offs produced in China. The same way, I also intend to take legal action against those who steal posts from this Blog and reproduce them without authorization and/or giving credit to the original author.
