A commercial industrial equipment company obtains a registered patent from the Nigerian Patents and Designs Registry for an agricultural grain drying machine. The patentee files a multi-million Naira patent infringement action in the Federal High Court against a rival machinery manufacturer.
The defendant files a statement of defense and counterclaim, seeking the total revocation and cancellation of the patent on grounds of lack of novelty and prior art anticipation.
Under Section 1 of the Patents and Designs Act (Cap P2 LFN 2004), an invention is patentable only if it is new, results from an inventive activity, and is capable of industrial application. Section 1(2) explicitly establishes an absolute novelty standard: an invention is new if it does not form part of the state of the art.
Step-by-Step Procedure to Resolve This Legal Matter:
- Preserve Contemporaneous Evidence: Collate physical receipts, verified bank timestamps, stamped letters, and electronic communication logs prior to formal intervention.
- Deliver Statutory Pre-Action Notice: Issue a formal written demand outlining the specific statutory breach and giving the opposing party statutory time to remedy the grievance.
- Engage Accredited Legal Counsel: Initiate judicial proceedings before the competent court of record or submit an official petition to the relevant regulatory commission.
The state of the art encompasses everything made available to the public anywhere in the world by written publication, oral disclosure, or prior public use.
Key Evidential Considerations & Statutory Benchmarks:
- Documented statutory breach and verified timeline of events.
- Jurisdictional competence of the regulatory agency or superior court.
- Contemporaneous written correspondences, notices, and financial records.
- Quantifiable proof of pecuniary loss or civil rights violation.
“The rule of law ensures that statutory rights and duties cannot be compromised by informal arrangements or administrative fiat; every citizen has the constitutional right to due process.”
— Nigerian Legal Precedent & Constitutional Jurisprudence
Under Section 9 of the Act, the Nigerian Patents Registry does not conduct prior substantive examinations of patent applications regarding novelty; patents are granted at the applicant’s risk. Consequently, when an infringement suit is instituted, the defendant can successfully counterclaim for patent revocation under Section 25 by tendering international technical journals, foreign patent registers, or commercial catalogs proving that the technology was publicly disclosed prior to the filing date.
Innovators and corporate technology developers must conduct comprehensive global prior art searches before incurring patent registration expenses. Tendering verified prior art publications in the Federal High Court completely invalidates spurious patent monopolies.
Adherence to strict novelty requirements preserves genuine industrial innovation and fair competition under Nigerian patent law.
Section 25 of the Patents and Designs Act empowers the Federal High Court to revoke a patent if the subject matter was not patentable under Section 1.
Prior confidential testing in a private laboratory does not constitute public disclosure, provided strict non-disclosure obligations were maintained.
Every commercial enterprise and individual in Nigeria must conduct affairs in strict adherence to governing statutory enactments, administrative guidelines, and binding judicial authorities. When rights are breached or statutory obligations neglected, approaching the competent judicial forum provides the lawful channel for redress.
Superior courts repeatedly condemn unilateral self-help, arbitrary administrative sanctions, and extra-judicial enforcement tactics.
Retaining experienced legal practitioners early in any commercial dispute significantly mitigates exposure to regulatory penalties and proprietary liabilities. Legal counsel conduct comprehensive due diligence, review operating authorizations, and establish robust contract management protocols.
Resolving ambiguities proactively preserves contractual relationships and prevents expensive litigation.
Disputants must systematically preserve all documentary records, contractual instruments, financial receipts, and official regulatory correspondence. Under the Evidence Act, primary documentary evidence carries paramount probative weight in civil and commercial proceedings across Nigerian superior courts.
For direct regulatory verification, official complaints, or accessing statutory registers without third-party fees, members of the public can consult the official portal of the Federal Inland Revenue Service (FIRS) Portal.
Maintaining complete audit trails ensures that claims can be substantiated convincingly during trial.

What specific documentation or contemporaneous evidence is most critical for a claimant or petitioner to assemble before instituting an action regarding How Does the Defense of Lack of Novelty and Prior Art Invalidate a Registered Patent in Nigeria? in a Nigerian court?
Thank you for raising this critical practical question. Under Nigerian civil procedure and the Evidence Act 2011, a claimant must assemble an unbroken chain of contemporaneous documentation prior to filing. This includes: (1) formal demand notices with verifiable proof of dispatch, (2) transaction trails (certified bank statements, receipts, and invoices), and (3) electronic printouts certified under Section 84 of the Evidence Act. In contract and statutory claims, courts attach paramount probative value to written instruments over oral averments. We strongly recommend having your legal practitioner conduct a pre-action documentation audit to verify that statutory pre-action protocols and limitation laws are strictly adhered to before originating process is sealed.
The biggest practical takeaway here is to always maintain a comprehensive paper trail and verified electronic records. Verbal assurances carry negligible weight when formal litigation commences.
