For clear, concise, cost-effective advice on intellectual property, patents and industrial designs
I have used my invention in my business for a couple of years. I now wish to sell the system. Can I patent the system?
Possibly. To get a patent in most territories your invention must be secret at the time you file the application. So long as the details of how your system works are not discernible from your use or any other disclosure, they are still secret and patentable.
