A key consideration for many patentees will be budgetary. A unitary patent will cover all those countries which have ratified the UPC Agreement by the date of grant. This will be at least 17, these being Austria, Belgium, Bulgaria, Denmark, Estonia, Finland, France, Germany, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Portugal, Slovenia and Sweden. There will be no validation fee for a unitary patent and only one translation will be required. However, there will be renewal (maintenance) fees, and for patentees who usually validate in fewer than four UPC states unitary protection is likely to be more expensive.
Patentees will, of course, also want to consider the litigation regime applying to unitary patents. These are mandatorily litigated in the UPC, and cannot be opted out. This has upsides and downsides. The main upside is obviously the advantage of central enforcement in a single action. A unitary patent also means it will only ever be subject to the UPC regime, whereas European patents not opted out will be subject to dual UPC/national jurisdiction for a transitional period (of at least 7 years) and susceptible to pre-emptive national actions for revocation which may block the ability of the patentee to use the UPC. On the downside, some teething problems are possible with the UPC meaning that enforcement may not be as straightforward as hoped. For some time, there will certainly be a good degree of uncertainty both as to procedure and outcome from the Court’s divisions while a body of case law and practice is developed. Further, the flip-side of central enforcement is central revocation, including by proactive actions begun in the UPC central division, meaning that what would otherwise have been a family of EPs may be revoked in one case.
