To apply for a patent now, you can go to the local patent office to apply, register a trademark, register and file it with the industrial and commercial administration department, and then go to the public administration for industry and commerce to apply for a trademark. It may take a little longer, but if your plaster is really good, I think it has great development prospects. Get the patent and trademark as soon as possible. When the time comes to make it yourself or transfer it, the economic value will be considerable. For some specific matters, you can go to the local industrial and commercial department to learn about it. I hope your plaster will be available as soon as possible! Just two months ago, my little nephew's hand got hot when he was holding the soup from the pot, and he immediately developed blisters. He was only less than two years old. It was really sad to see him, but he was sent to the hospital for treatment immediately, and he is still there now. alright. Where are you located and how can I contact you if necessary?
