A patent is a legal right granted by the UK Intellectual Property Office for a new invention. It allows the owner of the patent (the patentee) to take legal action against others who use his invention without his permission. The right has a maximum life-time of 20 years in most countries, from the date of the patent application. What a patent does not do is give the owner an automatic right to use the invention.
Apply for a Provisional Patent. A patent can incur far more expense than a startup is able to pay. During the process of shopping your idea around, a provisional patent can protect your idea for the first year. After twelve months, the provisional patent expires, however, with no option of being extended. Trademark Your Name.
