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.
When can I talk about my invention?
The general rule is 'file your patent first, then disclose'. Some countries, eg. USA, do allow disclosure first and then filing within 12 months. But most countries do not, and thus a non-confidential prior disclosure will 'knock out' your patent.
