I created this really unique pillow and I would like to apply for a design patent. The problem is that I've sold several of them, they have been in local magazines, and on TV. I know I should have patented the design before I put it out there, but I didn't think it would take off as much as it has now. Since it is my design, can I patent it now? If not, what would you recommend I do?
Also I have other pillow designs that I'm producing and would like to patent those as well. Would I need to get a design patent for each design or is there a way to bundle the collection together under 1 patent?
Thanks in advance!
