Resolving patent disputes in the UK
Patent disputes can be costly and time-consuming, but many can be resolved without going to court. Disputes typically arise in areas such as:
- patent infringement
- patent validity
- licensing
- patent ownership and entitlement
- opposition to patent applications
- breach of confidentiality or trade secrets
- post-grant patent amendments
To help businesses navigate these issues, the UK Intellectual Property Office (IPO) offers several alternative dispute resolution options. These can often resolve conflicts more quickly and at a lower cost than litigation.

Proving patent ownership
If someone challenges your right to a patent, you may need official documentation to prove ownership. The IPO can issue , which you can use as evidence in disputes, licensing negotiations, or legal proceedings.
When patent litigation is necessary
Litigation should only be a last resort due to its expense and complexity. However, it can provide a binding outcome and significant damages if successful. Find out how litigation fits into your enforcement strategy.
