So I haven't made anything to sell but I would like to make some baby stuff to sell mostly locally and maybe some online. One big thing I wanted to try my hand at was the grocery cart/highchair covers but someone told me that they were patented. I know there are a ton of companies that make similar things and I have no intention on copying any of them, just looking at a cart and going from there. How do I know if I'm in violation?
This question goes beyond just the covers, I would like to check whatever I may do in the future just to be on the safe side. It seems so hard to find resources on this and the patent office website is a huge maze. Where should I even begin?
Thanks for any help!
