What is patent infringement?

Patent infringement occurs when a third party makes, uses, sells or imports a patented product or process without the permission of the patent holder. Patents are exclusive legal rights granted to inventors, and infringement can occur whether it’s intentional or accidental. The consequences of unauthorised use can be significant, impacting your market share, business reputation and future innovation.

In the UK, patents are protected under the Patents Act 1977, and enforcement of rights is typically handled through civil litigation. It requires a detailed understanding of the patent in question, a careful analysis of the alleged infringement, and a tailored legal strategy to resolve the matter effectively – all of which our patent infringement lawyers are well-equipped to handle.
