The Trademark 100 Weekly: Tesco's All-Class Sweep, Walmart's AI Brand Push, and a Quiet Signal in the Class 42 Numbers
This week's Trademark 100 data reveals a supermarket filing all 45 Nice classes in one sweep, two US tech giants racing to lock down AI-adjacent marks across both registers, and a 61.6% collapse in UK Class 42 software-services filings that tells a more uncomfortable story about where AI brand-building is really happening.

Tesco's Full-Spectrum Sweep
Tesco PLC leads this week's index with 86 filing events across all 45 Nice classes. Every single one. Class 1 (chemicals) through Class 45 (legal services).

That number demands explanation, because most companies - even large conglomerates - do not operate across that breadth. Tesco does, sort of. It sells food, clothing (F&F), financial products, mobile services, fuel, and now, apparently, has its eye on something larger. In May, the UK IPO registered UK00002116694 for the word mark 'TESCO' in Class 36, which covers banking, insurance, and investment management. Haseltine Lake Kempner LLP filed it, and it was Tesco's first-ever registration in that class. The week's 86-event sweep - spanning Classes 1 through 45 with existing marks like UK00001545111 and UK00002258927 - looks like a systematic portfolio audit and re-anchoring exercise: a legal team refreshing the estate, shoring up renewals, and extending protection across every commercial territory the brand now touches.
The Class 36 registration from May tells you where Tesco's strategists are pointing. The Group sold Tesco Bank's retail banking arm to Barclays in 2024 but retained insurance and financial services operations. Protecting 'TESCO' in Class 36 is not nostalgia. It is a statement of intent. When a retailer with roughly £70 billion in annual revenue and 28% UK grocery market share also files across Classes 9 (software), 35 (retail services), 38 (telecoms), 42 (software-as-a-service), and 44 (medical services), the portfolio is not describing what the business currently does. It is describing what the business does not want a competitor to fence it out of doing. Defensive filing at this scale is a strategic option preserved, not a product launched.
Walmart and Alphabet: The AI-Adjacent Race
Walmart (52 events, US and UK) and Alphabet (51 events, US and UK) filed in near-identical volumes this week, and the class overlap between them is instructive. Both concentrate activity in Class 9 (software and electronics), Class 35 (advertising and retail services), Class 36 (financial services), Class 38 (telecommunications), Class 41 (entertainment and education), and Class 42 (software-as-a-service and technology services). That is precisely the class footprint of a company building, or protecting, an AI-integrated consumer platform.
Walmart's context is not subtle. The retailer secured nearly 50 US patents in 2026 from the USPTO, including an automated markdown system for its e-commerce operation and a machine-learning demand-forecasting tool that draws on purchase history, payment methods, and customer identifiers. Its trademark activity in Classes 9, 35, and 42 is the brand layer on top of that patent infrastructure: locking down product names, service-line identifiers, and platform marks before competitors can establish prior rights in the same territory. Walmart also confirmed a sweeping rollout of electronic shelf labels across its roughly 5,200 US stores by 2027. The trademark portfolio is catching up with the operational reality.
For Alphabet, the Class 14 and Class 28 inclusions this week are worth attention: jewellery and watches, and games and toys respectively. Google has been building its hardware consumer proposition for years - Pixel phones, Nest devices, earbuds - and Class 14 suggests Alphabet may be testing the boundaries of wearables beyond earbuds. Class 28 points toward gaming, consistent with Google's persistent but never-quite-dominant position in interactive entertainment. The dual UK and US filing pattern confirms that both registers are being maintained in tandem, which is standard practice for any brand intending genuine commercial use in both jurisdictions post-Brexit.
Amazon's Quiet Depth
Amazon (51 events) filed across 35 Nice classes this week, the broadest class spread of any single filer in the top five bar Tesco. The span runs from Class 6 (metal goods) through Class 45 (legal services), with example applications 98086534, 97978133, 97978132, and 98338558 anchoring the US register activity.
This is portfolio maintenance with strategic texture. Amazon's breadth across Classes 7 (machinery), 12 (vehicles), 22 (ropes and fibres), and 31 (live plants and agricultural goods) reflects the reality of a company that has built fulfilment infrastructure touching almost every physical goods category. Class 40 (treatment of materials) and Class 39 (transport and storage) are the logistics marks. Class 44 (medical and veterinary services) covers the healthcare push: Amazon Pharmacy and Amazon Clinic are both active businesses. Classes 9 and 42 together cover the AI software layer underneath all of it.
Amazon files this broadly because it must. The cost of not filing a class and later discovering a squatter has established prior rights in a jurisdiction is far higher than the cost of the filing itself. At Amazon's commercial scale, trademark maintenance is not a legal function. It is operational risk management.
Disney: Entertainment IP as Hard Currency
The Walt Disney Company (36 events, US and UK) is the week's most strategically readable filer. Disney's activity concentrates in Classes 9, 14, 16, 18, 20, 21, 24, 25, 28, 30, 35, 39, 40, 41, 43, and 45. Strip out the logistics and retail classes and the core remains: software, entertainment, toys, clothing, food, and hospitality.
The majority of Disney's trademark portfolio historically sits in Class 41: entertainment services, theme park services, production of motion picture films and television programmes. Recent filings have trended toward brand extensions. 'TRON ARES' was filed in September 2024 covering entertainment services and software; 'ELECTRIC BLOOM' across entertainment, toys, clothing, and electronics in October 2024. The pattern this week - 36 events touching Classes 28 (games/toys), 25 (clothing), 9 (software), and 30 (food) - is Disney's standard franchise monetisation machinery: a new title gets filed across every commercial exploitation category before the announcement. The trademark register is often the first public evidence that a Disney project exists.
For IP practitioners, Disney's Class 40 and 43 inclusions (treatment of materials; restaurant services) point at the parks and experiences business. Disney has been aggressively expanding resort offerings globally. A Class 43 filing is often the earliest indicator of a new food or hospitality experience tied to a franchise property.
The Class 42 Collapse: What It Actually Means
Beyond the week's individual filers, there is a macro signal that warrants direct attention. UK Class 42 trademark filings - the class covering software-as-a-service, AI tools, platform technology, and scientific research services - recorded just 2,841 applications in Q3 2026, a fall of 61.6% on the prior period. That is not a rounding error. That is a structural shift.
Three explanations compete. First, the AI industry is maturing past the startup-naming phase: fewer new AI brands are being launched, and the ones that exist are focusing on product development rather than brand proliferation. Second, increased scrutiny of AI-service descriptions at the USPTO and UK IPO, combined with the EU AI Act's classification requirements, which came into full effect for high-risk systems in August 2026, may be creating filing hesitancy among companies uncertain how to describe their services in ways that survive examination. Third, and most plausible given this week's data, large incumbents are dominating the class: Walmart, Alphabet, Amazon, and others are sweeping Class 42 within broader portfolio actions, crowding out the long tail of smaller applicants who might otherwise have occupied the space.
IP filings at the EUIPO reached record levels in the first half of 2026, up 4.7% year-on-year, driven by strong demand for EU trademarks. The UK collapse in Class 42 therefore stands out starkly against the continental trend. Post-Brexit filing divergence is real, and it is accelerating.
The Pattern This Week Signals
Five filers. Two retailers, one search-and-AI conglomerate, one e-commerce platform, one entertainment empire. They share three traits: all are filing simultaneously across both UK and US registers; all are protecting AI-adjacent classes (9, 35, 38, 41, 42) as a matter of routine rather than exception; and all are using trademark activity to pre-position for product categories where launch decisions have not yet been publicly announced.
The statute governing UK trademark registration - the Trade Marks Act 1994, implementing the EU Harmonisation Directive before it was absorbed into domestic law post-Brexit - requires that marks be filed in good faith with a genuine intention to use. A filing across all 45 Nice classes strains that requirement. At some point, a company filing Class 13 (firearms) and Class 23 (yarns for textile use) alongside its core retail marks invites a non-use cancellation action from a competitor. The more interesting legal question, as AI-powered products blur the line between software (Class 9), retail services (Class 35), and platform technology (Class 42), is whether the traditional Nice classification system is adequate for the entities it is being asked to describe.
The short answer is no. But that is a problem for the next WIPO revision cycle, not for the companies filing this week. They are playing the rules as written.
