Nike Free got sued by Reebok

Reuters: Reebok sues Nike for patent infringement Oregonlive.com: Reebok sues Nike over its flexible soles I am not reading enough to have missed out this big news recently.... Actually, Nike is good in marketing....u can see why..but did they file any patent for it??? Reebok created this shoes for another purpose and dunnoe whether it goes into market or not and nobody knows about it. anyway, is interesting to see The Official patent infringement lawsuit to sue NIKE dated 3 apr 2007. And also "Reebok's patent on collapsible shoes" is dated 30 jan 2007.... hmmm...something interesting here....NIKE Free has been in the market for at least 2 years (still remember i got a free pair from MR25 ultramarathon 2005) and now they kena sued for a new patent dated less than 3 months ago...... hahaaa...a closed look at the details and you will see that it was actually filed 18 july 2002...is Nike Free out in market then? and so this is the patent rule...u filed early, no others can file the same thing when it is in process of getting the grant...once u get it granted, u can start to sue pple. hmmmm...from the patent drawing, I have seen similar shoes design in the market.... Interestingly, it took 5 years for this patent to get granted.....now we know Reebok has been waiting for this day to come for the past 2-3 years and finally They JUST DID IT!!!
