Brexit's Final Bite: How Evidence Shifts and Fee Hikes Are Forcing IP Attorneys to Rebuild Trade Mark Workflows

The three-headed beast of UK intellectual property practice changes has arrived. On 1 January 2026, five years after Brexit cloned EU trade marks into UK registrations, EU use ceased counting as genuine use in UK proceedings. Three months later, UKIPO fees jumped 25% (the first increase since 1998). Layered beneath both: new examination guidance from the Sky v SkyKick Supreme Court decision that's turning routine broad specifications into bad faith objections.

For IP attorneys, this isn't academic. Portfolios are exposed, clearance searches need reframing, and evidence-gathering workflows require fundamental reconstruction.

The Evidence Problem

Start with the hard deadline. Under section 46(1) of the Trade Marks Act 1994, UK trade marks face revocation after five years of non-use. The "comparable" marks created on 1 January 2021 (exact copies of EU trade marks that existed at Brexit) could previously rely on EU use to defend against cancellation actions.

Not anymore. From 1 January 2026, owners must demonstrate genuine UK use or face third-party challenges. The UKIPO won't initiate these proceedings, but any competitor can file a cancellation action.

The practical challenge runs deeper than expected. Many multinational companies consolidated their evidence collection under "EU" categories for decades. Invoices, delivery confirmations, marketing materials: all bundled together without clear UK segregation. That consolidated approach now creates vulnerability.

Section 46(3) TMA adds a procedural trap. Evidence of use that begins within three months before a revocation application may be disregarded unless the owner can prove preparations started before they became aware of the potential challenge. Late-stage UK market entry looks defensive, not genuine.

The Cost Squeeze

The 1 April 2026 fee increases compound the pressure. A single-class UK trade mark application rises from £170 to £205. Opposition proceedings, renewal fees, recordals: all increase by roughly 25%. For high-volume filers managing hundreds of marks, the annual budget impact is material.

The UKIPO justifies the increase by pointing to seven years without design and patent fee changes, and 28 years of frozen trade mark fees. Compared to other major jurisdictions, UK fees remain competitive. But the timing creates a perfect storm: just as attorneys need more evidence-gathering and portfolio auditing, the cost of maintaining UK rights rises substantially.

Specification Reckoning

The SkyKick fallout reshapes how applications are drafted and examined. Practice Amendment Notice 1/25, effective immediately, instructs UKIPO examiners to actively raise bad faith objections against "manifestly and self-evidently broad" specifications.

Applications covering all 45 Nice classes or all goods in Class 9 now automatically trigger objections. But the guidance goes further. Even traditionally acceptable broad terms like "computer software" or "clothing" face scrutiny if they don't reflect genuine commercial intent.

The test is contextual: what's good faith for Microsoft isn't necessarily good faith for a two-person startup. Applicants must now provide commercial rationale for broad specifications (business plans, market research, anything demonstrating genuine intent to use the mark across the claimed scope).

For attorneys, this means front-loading the specification review process. The days of filing broad protective registrations and narrowing later are ending. Each term needs justification at filing.

Portfolio Triage

The combined effect demands immediate portfolio assessment. Attorneys need to identify:

• UK cloned marks (registrations beginning "UK009" or "UK008") without UK use evidence
• High-value marks where UK use evidence exists but needs proper documentation
• Registrations with broad specifications filed before SkyKick that might face counterclaims

For marks with limited UK use, the options are stark. File new applications with narrower specifications? Commence token use and hope it survives section 46(3) scrutiny? Or accept the loss and rely on unregistered rights?

Automation becomes essential. Watch services need updating to flag potential cancellation actions against vulnerable marks. Evidence collection systems require UK-specific documentation protocols. Cost modelling must incorporate the new fee structure across renewal cycles.

The Practical Reality

This isn't a one-time adjustment. The evidence requirements create ongoing compliance obligations. UK use must be genuine: real commercial activity, not token sales designed purely to maintain registrations. Documentation standards rise as proof requirements tighten.

The SkyKick guidance affects both offensive and defensive strategies. Opponents can now counterclaim bad faith against registrations with broad specifications. Rights holders enforcing their marks face additional exposure if their own registrations contain unjustifiable scope.

Client education becomes critical. Many don't understand that their "EU trade mark" actually generated two separate registrations after Brexit. They assume continued EU use protects UK rights indefinitely. The 1 January 2026 cutoff makes that assumption expensive.

Workflow rebuild isn't optional. The evidence shift, fee increase, and examination changes create new baseline requirements for competent UK trade mark practice. Attorneys who adapt their systems survive. Those who don't face client exposure and professional liability risk.

The next procedural milestone: UKIPO guidance on the fee transition period, expected early 2026. But the message is clear: Brexit's trade mark consequences have only just begun.
