What the Unitary Patent trades for lower cost

Once the European Patent Office (EPO) grants a European patent, you face a choice. You can take the classic route and validate it in chosen countries, or you can ask for a Unitary Patent, a single right across the participating states (EPO Unitary Patent page). This is a trade, and the price is concentrated risk.

What you gain

The appeal is simplicity at scale. One right means one renewal fee across all participating states, where a classic patent needs renewals country by country (EPO cost page). The saving depends on how many countries you would otherwise pick. The EPO publishes a break-even estimate (EPO FAQ). One law firm argues that small footprints can be cheaper the classic way (Marks & Clerk). The EPO is promoting its own system, so in our judgment you should run the numbers for your actual country list.

What you risk

In our judgment, a Unitary Patent is a single point of failure, since one central revocation can end protection in every participating state. The same structure helps you when you are the one enforcing, because one action covers a wide market. Whether that trade suits you depends on how strong the patent is and how much is at stake.

The court and the transition

The Unified Patent Court (UPC) is the shared court behind this system. The treaty set a seven-year transitional period. During it, owners of classic European patents can opt out of the court, unless a UPC action has already been brought. They can also withdraw an opt-out, unless a national action has been brought. The period may be extended by up to seven years after consultation (UPCA Art. 83). In our judgment, opting out is a way of keeping a patent out of the central court while you see how the court behaves.

An open question

Whether an opt-out survives the end of the transitional period is contested. Commentators disagree (Fish & Richardson; Bristows). Treat this as unsettled, and get specific advice if a valuable patent depends on the answer.
