For many businesses patent filing can follow a familiar script: an initial UK application, followed by an International application under the Patent Cooperation Treat (PCT), and later entry into Europe via a European patent application under the European Patent Convention (EPC). Whilst this approach offers convenience and broad coverage, it may not always be the most effective or commercially appropriate strategy.
An important alternative is direct national patent filings, which remain available as either an alternative to, or alongside regional systems such as the EPC. National filings allow businesses to target protection precisely where commercial activity is expected. For businesses operating in only a small number of markets this can reduce costs compared with pursing and maintaining broader regional coverage.
National patent offices may also offer faster prosecution, meaning that granted patents can be obtained more quickly. Early grant can be valuable when engaging with investors, strengthening commercial credibility.
Regional filings, such as EPC applications, undoubtedly provide an efficient route to protection across much of Europe through a single examination process. However, this efficiency can come at the cost of lengthier timelines and higher overall expense. Concentrating filings in a single regional system can also concentrate risk. Relying solely on an EPC application means that delays, or adverse decisions affect an entire European portfolio at once. By contrast, a strategy that includes national filings spreads risk across multiple offices, reducing dependence on any single authority.
It is also important to recognise that regional patent systems do not always align with political borders. National filings can sometimes cover territories that fall outside regional frameworks, a
consideration that is often overlooked. A notable example is Denmark. Denmark is a full contracting state to the EPC and validating a European patent in Denmark gives protection in mainland Denmark, however it does not cover Greenland or the Faroe Islands. These territories are explicitly excluded from Denmark’s EPC territorial extension. For businesses operating in Arctic technologies, such as mining, energy, or fishing this exclusion is important to consider, and national fillings in Denmark should be considered.
Ultimately, effective patent strategy is an strategic business decision. Careful alignment of filing routes with commercial realities can reduce cost, avoid territorial gaps, and deliver more meaningful protection.
