Your priority date is the official date your invention enters the patent system. From that moment, no one else can file the same idea and claim priority over you. For fundraising, it changes one conversation: instead of "we're planning to file," you can say "we filed in March." That is a different answer to a different question.

Time is critical in this case. In most jurisdictions, a public disclosure before filing can jeopardize your patent rights. Contact us as soon as possible. We may still be able to help, depending on the circumstances and timing.

You can file yourself. But a patent is only as strong as its claims, and claims are where most self-filed applications fail. A poorly drafted patent can be designed around or invalidated entirely. ptntpwr gives you a qualified European patent attorney reviewing every filing, without the hourly rate.

Prio secures your priority date and gets you an EPO search report: feedback of the European patent administration on your invention’s patentability, within your budget. World includes everything in Prio, plus a PCT filing at month 12 that keeps protection open in 150+ countries for up to 18 months. Both are flat-fee, no surprises.

Three criteria matter: your invention must be new, it must not be obvious to someone working in the same field, and it must have a practical use. If you can say yes to all three, it is worth a conversation. ptntpwr includes a free patentability check before you commit to anything.
