Wow, this is a day that I never thought I would see. The Lemelson Partnership has a number of patents (4,338,626, 4,511,918, 4,969,038, 4,979,029, 4,984,073, 5,023,714 , 5,067,012, 5,119,205, 5,128,753, 5,144,421, 5,249,045, 5,283,641, 5,351,078) which basically cover all of barcode reading as well as computer vision. These patents cause a huge amount of consternation among the computer vision community for years. The problem is, people who have patents like this are easier to pay off than to fight in court.
The Lemelson partnership has made a lucrative bsiness for the past few years collecting royalties off of every machine vision, computer vision and barcode reader customer in the US. Apparently to the tune of $1.5 Billion. Yes that is with a B. I’m a little amazed that he never tried to sue any university that had the gall to have a computer vision department. The problem is that there was no giant in the industry that could afford to bring the fight to court.
Another interesting aspect to the case is that the Lemelson partnership (Lemelson himself died in 1997) never actually sued the companies that make the vision products, just the customers, notably Motorola and Ford. (Both settled before the case went to court.) One has to wonder if they did this, because the companies that actually made their living off the stuff would fight it.
Fortunately the industry has grown to the point in the past few years that, while there is no Microsoft to knock it down, there are a few companies that have become large enough to take them to court, Symbol in barcodes, and Cognex in computer vision. They were not sued themselves but sued the Lemelson partnership to protect their customers. Their cases were combined and they won against that juggernaut. Symbol also released their own press release although that one is for barcodes, not the more computer vision type patents.
When I started computer vision in 94, there were people who actually weren’t entering the field because of Lemelson. When someone shows up and makes Boeing and Ford pay, how can the little guys hope to do anything at all? I’m glad these were finally blown out of the water.
