Patent System & Process
Patent System in United Kingdom
UK patents are managed by UKIPO under a first-to-file system. Invention patents are valid for 20 years from the filing date, with annual renewal fees due from year 5. The UK is a PCT member; national phase entry is due within 31 months of the priority date. Post-Brexit, EUTMs no longer cover the UK, but the UK remains an EPO member — European Patents (EP) can still be validated in the UK.
Patent Types ▾
UK patent protection options:
**UK National Patent:** Filed directly with UKIPO; full examination required; valid 20 years; annual renewal fees from year 5.
**European Patent (EP) validated in the UK:** Examined and granted by EPO; validated in the UK; has the same legal effect as a UK national patent.
**No separate utility model:** The UK does not have a secondary patent (utility model) system distinct from its full patent.

PCT National Phase Entry — UK ▾
- Deadline: 31 months from the priority date
- Language: English (English version required)
- National phase entry fee required
- Examination request must be filed
- Can enter the UK national phase directly via UKIPO, or via EPO (designating the UK)
**Practical note:** If targeting multiple European countries plus the UK, entering the European phase via EPO and validating in the UK upon grant is typically more cost-effective than a separate UK national phase entry.

UK Patent Annual Renewal Fees ▾
UK patent annual renewal fees are due from year 5, increasing each year. Fees are due annually starting from the 5th anniversary of the filing date. A 1-month grace period applies with a surcharge; beyond that the patent lapses. Under specific conditions, a lapsed patent can be restored within 13 months of lapsing. Current fees are listed in the UKIPO fee schedule (updated annually).

Examination Process and Timeline ▾
UKIPO examination process:
1. Filing
2. Search Report — UKIPO issues search report sent to the applicant
3. Publication (automatic after 18 months)
4. Request for Substantive Examination (must be filed within 6 months of publication or within specified period)
5. Substantive Examination — examiner assesses novelty and inventive step
6. Grant or rejection
Typical timeline: approximately 3–5 years from filing to grant (including OA responses). UKIPO offers accelerated examination via the Green Channel and PPH.

Novelty Grace Period ▾
The UK allows a 6-month grace period in limited circumstances (disclosure at international exhibitions, or disclosures made through breach of confidence). Commercial sales and general academic publications are NOT covered. For jurisdictions requiring absolute novelty (mainland Europe via EPO, China), file before any disclosure.

European Patents and UK Patents Post-Brexit ▾
Brexit does not affect EPO's relationship with the UK — the UK remains an EPC member, and European Patent validation in the UK is unchanged.
**However, Brexit did affect:**
1. EUTMs no longer cover the UK (from January 1, 2021)
2. EU Community Designs (RCDs) no longer cover the UK
3. Some EU-related filing priority rules in the UK
**"Comparable UK Trade Marks":** EUTMs registered before December 31, 2020 were automatically cloned into UK Comparable Trade Marks with the same priority date, requiring no action.

DAS Support ▾
UKIPO is a WIPO DAS participating office. Applicants can use DAS to provide priority documents from UK applications to other participating offices without separate certified paper copies.

Supplementary Protection Certificate (SPC) ▾
The UK allows Supplementary Protection Certificates (SPCs) for patents covering products subject to regulatory approval (e.g., pharmaceuticals, plant protection products), extending protection by up to 5 years (plus up to 6 months for pediatric extensions). Post-Brexit, UK SPCs are independent of EU SPCs — separate applications are required; EU SPCs no longer cover the UK.

Trademark System & Process
Trademark System in United Kingdom
UK trademarks are managed by UKIPO under a first-to-file system. Registrations are valid for 10 years from the application date, renewable indefinitely. Post-Brexit, EUTMs no longer cover the UK — new UK trademark applications must be filed separately with UKIPO. EUTMs registered before December 31, 2020 were automatically converted to Comparable UK Trade Marks. The UK joined the Madrid Protocol in 1996 and can be designated via Madrid.
Brexit and UK Trademarks ▾
**Pre-Brexit (before December 31, 2020):** EUTMs covered the UK — no separate UK filing needed.
**Post-Brexit (from January 1, 2021):** New EUTMs do not cover the UK; a separate UKIPO filing is required.
**Comparable UK Trade Marks:** EUTMs registered before December 31, 2020 were automatically cloned into UK Comparable Trade Marks on January 1, 2021 with no action required from holders; original priority dates were preserved.

UK Trademark Examination Process ▾
UKIPO examination process:
1. **Formal examination** — Format check
2. **Absolute grounds examination** — Distinctiveness, descriptiveness, deceptiveness, etc.
3. **Relative grounds search (proactive)** — UKIPO proactively searches for conflicting earlier marks and notifies earlier rights holders (unlike EUIPO which does not proactively examine relative grounds)
4. **Publication period (2 months)** — Successful applications are published; oppositions can be filed within 2 months
5. **Registration** — Registered if no successful opposition

Term and Renewal ▾
UK trademarks are valid for 10 years from the application date, renewable indefinitely in 10-year increments. Renewals may be filed within 6 months before expiry; a 6-month post-expiry grace period applies with a surcharge. Renewals are per class — unused classes can be dropped. **No proof of use is required for renewal** (unlike the US), but registrations unused for 5+ consecutive years are vulnerable to third-party cancellation.
Source: UK Trade Marks Act 1994 §§42–43, §46
Non-Use Cancellation (5-Year Non-Use) ▾
A UK trademark unused for 5 consecutive years is vulnerable to a revocation application by any party. The registrant bears the burden of proving use or providing legitimate reasons for non-use. Evidence of use must cover periods within the 5-year window.
Source: UK Trade Marks Act 1994 §46
Madrid System Designation of the UK ▾
The UK joined the Madrid Protocol in 1996. The UK can be designated in Madrid international applications (now independent from EU since Brexit). UKIPO examines Madrid designations under UK national law, including proactive relative grounds searches. Any provisional refusal must be responded to in English within the prescribed period, through UKIPO or an authorized representative.

Series Trademark Applications ▾
The UK allows "series trade mark" applications — registering two or more marks with minor differences in a single filing, provided the marks differ only in immaterial respects (e.g., color variants, font variations). This can reduce filing costs while protecting multiple forms of the same mark.

Patent Annuity
United Kingdom Patent Annuities
UK patent annual fees are due from year 5, increasing each year. Fees are due by the anniversary date; a 1-month grace period with surcharge applies. Beyond this the patent lapses, but can be restored within 13 months under specific conditions. Professional renewal tracking via a patent management system or agent is strongly recommended.
Source: UK Patents Act 1977 §25; UKIPO fee schedule
Trademark Renewal
United Kingdom Trademark Renewals
UK trademark registrations renew every 10 years. No proof of use is required. Renewals may be filed within 6 months before expiry or within a 6-month post-expiry grace period (with surcharge). Renewals are class-by-class; unused classes can be removed. Note: although renewal does not require use, registrations unused for 5+ years remain vulnerable to cancellation.

FAQ
Common Questions — United Kingdom IP
Do I need to file a separate UK trademark after Brexit? ▾
Yes. From January 1, 2021, new EUTM applications no longer cover the UK — a separate UKIPO filing is required. EUTMs registered before December 31, 2020 were automatically converted to UK Comparable Trade Marks and remain effective in the UK.
What is the difference between a UK national patent and a European Patent (EP) in the UK? ▾
Both have the same legal effect after grant (both are UK patent rights). The main difference is the filing route and examiner: UK national patents are filed with and examined by UKIPO; European Patents (EP) are examined by EPO and validated in the UK after grant. If multiple European countries are targeted, the EPO route is typically more efficient; for UK-only, direct UKIPO filing may be more cost-effective.
What is the PCT national phase entry deadline for the UK? ▾
31 months from the priority date (UKIPO uses 31 months, not 30). English language documents and applicable fees must be submitted, and an examination request must be filed.
How does UK trademark examination differ from EU trademark examination? ▾
Key difference: UKIPO proactively searches relative grounds (conflicts with earlier UK/Madrid marks) and notifies earlier rights holders; EUIPO does not proactively examine relative grounds (handled only via opposition). Both examine absolute grounds. UKIPO's publication period is 2 months; EUIPO's is 1 month.
Does UK trademark renewal require proof of use? ▾
No. UK trademark renewals do not require proof of use. However, registrations that have been unused for 5 consecutive years are vulnerable to third-party revocation applications, at which point the registrant must prove use.
Has the UK joined the Madrid trademark system? ▾
Yes. The UK joined the Madrid Protocol in 1996. Post-Brexit, the UK continues to participate independently in the Madrid system as a separate designatable country.
Does the UK offer accelerated patent examination? ▾
Yes. UKIPO offers:
1. Green Channel: Accelerated examination for environmentally-friendly technologies; free to request
2. PPH (Patent Prosecution Highway): Accelerated examination if a corresponding application has received a positive outcome in a partner jurisdiction
3. Paid accelerated examination program: Available on request with a fee
If PPH eligibility exists, PPH is generally recommended as the first option.
Is there a post-grant opposition process for UK patents? ▾
Yes. After UK patent grant, any party can apply to UKIPO for revocation on grounds such as lack of novelty, lack of inventive step, or insufficient disclosure. Unlike EPO, the UK does not have a centralized 9-month post-grant opposition window — revocation applications can be filed at any time. Defendants in infringement proceedings may also counterclaim invalidity.
Why is UKIPO sometimes also called IPO internationally? ▾
UKIPO's official short name is simply IPO (Intellectual Property Office) in domestic UK documents. In international contexts, UKIPO is used to distinguish it from other countries' IP offices. This page uses UKIPO for clarity.
Does the UK still participate in the European Patent system post-Brexit? ▾
Yes. Brexit concerned EU membership. The European Patent Convention (EPC) and EPO are independent of the EU. UK's exit from the EU did not affect its EPC membership. EPO filings can still designate the UK, and European Patents can still be validated in the UK after grant.
How does the UK trademark opposition process work? ▾
After passing UKIPO's absolute grounds examination, a trademark application is published in the Trade Marks Journal for 2 months. During this period, earlier rights holders or any interested party can file an opposition. Opposition proceedings are quasi-judicial — both parties submit statements, and a UKIPO Hearing Officer issues a decision.
Who is responsible for paying UK patent and trademark renewal fees? ▾
Annual fees and renewal fees are the responsibility of the registered rights holder (patentee/trademark owner), or their authorized patent agent/IP attorney. If rights have been assigned, ensure the assignee takes responsibility. Using a professional agency to centrally manage all UK IP renewal obligations is strongly recommended to avoid lapse through missed payments.
