I have an idea for protecting a plant that I've not seen, but I have seen something similar to it. There is a patent on that other product, but my idea would provide a different look and style as well as a variety of sizes. How can I find out if the other product is being sold, or if the patent is available? Also, if MINE is a different object, then may I patent MY object, even though it is similar to the other one? I'm NEW to this arena so I'm not sure how much to say without revealing my idea. Thank you for any comments and help.
