Patents in the United Kingdom
Patents
We act directly before the UKIPO through our UK-qualified Chartered Patent Attorneys and a managed address in London.
This enables us to provide seamless, efficient, and cost-effective handling of UK patent applications for our clients, alongside trusted patent analysis and legal advice from a British perspective.
Our UK Patent Services
Håmsø Patentbyrå assists companies and inventors worldwide in securing patent rights in the United Kingdom – both through the European Patent Office (EPO) and via direct filings with the UK Intellectual Property Office (UKIPO).
Our UK practice is led by our own UK-qualified Chartered Patent Attorneys, Andy Caulfield and Richard Weaver, both of whom are full-time employees at Håmsø and work from our offices in Norway. This set-up means our clients can save costs they would otherwise need to spend on a UK-based intermediary.
Further strengthening our UK expertise, our team also includes Rob Valkass, a former Senior Patent Examiner with almost a decade of experience at the UKIPO. Rob brings unique insider knowledge of UK patent procedures, helping our clients navigate the system strategically and effectively.

Andy Caulfield
Choosing Håmsø
Our team delivers high-quality prosecution and strategic patent services without the overhead of a UK-based firm.
With full authorisation to act before the UKIPO and a managed London address, we ensure seamless, VAT-exempt service – from application to grant.

Håmsø: A smart move for cost-effective UK filings
Norway hasn’t always had a reputation for affordability in professional services, but that’s changing.
Norway’s reputation may be a high-cost country, which is correct for e.g. food and drinks, but it has in fact never been the case for professional services. In addition, the Norwegian krone (NOK) has been on a weaking trend over several years. You will therefore find that our attorneys’ rates and our fees are cost-competitive compared with UK-based firms.
Working with us is a cost-effective choice, and you will get the best of both worlds: UK-qualified Chartered Patent Attorneys with international experience, alongside the benefit of Norway’s competitive pricing. For clients outside Norway, our services are VAT-exempt—bringing costs down even further.
We file directly with the UKIPO, cutting out middlemen to deliver efficient, reliable service and reduced overall fees.
Håmsø offers trusted support for your UK filings with the quality you expect, at a price you might not.
Comprehensive patent services for the UK market
