Today i got a letter from a lawyer saying that my website infringed U.S. Patent No. 6,275,821, entitle "Method and system for executing a Guided parametric Search"
Basically it is says:
"The patent is for a “search method” where instead of a hierarchical approach, the application uses family groupings to narrow products (they call it guided parametric search). A hierarchical approach would be one where in order to get to Small Red Widgets I would have to first go to Widgets, then to Red Widgets, then to Small Red Widgets. If you wanted to get to Small Blue Widgets, I would have to go back to the top of the hierarchical tree and then select Blue and then Small to get my Small Blue Widgets. The issue with this being you may not know how your end user may prioritize those things. They may want to see all the Small Widgets and don’t care about the color, but in this hierarchical approach, that isn’t possible as its a branch past the color selection. Magento handles this by having grouping of objects based off these characteristics. I can, just as easily start of with all Small Widgets as I could with all Blue Widgets. This seems to be what Kelora is claiming as their patent."
Any of you got this letter? What do you advise me to do?
I will contact a patent attorney to see what do i need to do
