The Sabaf SpA v MFI Furniture Centres Ltd case, decided by the House of Lords on 14 October 2004, remains a landmark decision in patent law. The ruling clarified important principles regarding inventive step and the concept of collocation, shaping how patents are evaluated for nearly two decades.
Background and Personal Insight
I was the principal solicitor representing MFI in this case, which ultimately settled with the claimant. This experience as a young patent litigator significantly influenced my career, giving me the confidence to establish Lawdit Solicitors as a sole practitioner.
Impact of the Case
The case’s ruling has had a lasting influence on UK patent law, particularly on how courts assess inventive step and combinations of known elements in patent claims.
Assessment of Inventive Step
The House of Lords provided clarity on the evaluation of inventive steps:
- Each feature of the claimed invention must be assessed individually.
- Features deemed obvious in light of prior art cannot contribute to the overall inventive step of the invention.
This ruling reinforced the rigorous standards for evaluating whether an invention is genuinely innovative.
The Concept of Collocation
The case also addressed collocation, where a patent claim combines known elements that operate independently without producing a synergistic effect. The court ruled:
- If the elements function separately and fail to create a new and inventive synergy, the combination is not patentable.
- In Sabaf’s case, the combination of features was deemed a collocation and thus obvious.
This judgment has guided courts and patent examiners to distinguish between inventive combinations and non-inventive collocations.
Lessons Learned
- Synergy is Crucial: The Sabaf case underscored the importance of synergy in patent claims. For a combination to be patentable, the features must work together to produce a unique result.
- Rigorous Evaluation of Inventive Step: Courts and patent examiners now apply stricter scrutiny to assess whether individual components of a claim add to its inventive step.
- Judicial Precedent in Patent Litigation: Sabaf established a benchmark for interpreting inventive step and collocation, influencing subsequent rulings in patent law.
Continuing Relevance
Two decades later, the principles from Sabaf v. MFI remain essential in UK patent law. The case continues to inform how inventors and legal professionals draft and defend patent claims.

Collocation underscores that combining independent elements without synergy does not meet the inventive step requirement, shaping patent assessments globally. - How did Sabaf v. MFI influence patent litigation?
It clarified the evaluation of inventive step, emphasising the need for synergistic effects, influencing patent claims and litigation strategies.
