How long does an international PCT patent application last for?
In most countries, 30 months from the earliest priority date. Some jurisdictions, eg. Europe and the UK, provide 31 months.
Unlike most countries, America provides a 12 months grace period from first disclosure in which a patent application can still be filed. Therefore, even if publicly disclosed, you may still be entitled to valid patent protection for your invention in at least the USA.
