1. Legal Framework in Ukraine (Context First)

In Ukraine, trademark protection is governed primarily by:

• The Law of Ukraine on the Protection of Rights to Marks for Goods and Services
• The Civil Code of Ukraine (IP provisions)
• International treaties such as the Paris Convention and TRIPS Agreement

For AR cultural festivals, trademarks may cover:

• Festival names (word marks)
• Logos used in physical + AR environments
• Digital avatars or curated AR spaces
• NFTs representing cultural artifacts or tickets
• Interactive mobile app branding

Key legal issue:

Whether trademark use in digital/AR spaces is:

• “Use in commerce”
• Likely to cause “consumer confusion”
• Dilution of cultural brand identity

2. Why AR + Digital Curation Creates Trademark Complexity

Hybrid festivals (physical + AR overlays) introduce problems like:

• Same mark used in physical Kyiv event + global AR layer
• Unauthorized AR overlays placed on real cultural sites
• NFT-based cultural artifacts sold under similar festival names
• Digital curation platforms aggregating festival content under confusing branding

This makes courts rely on analogical reasoning from tech trademark cases.

3. Key Case Laws Relevant to AR Cultural Festivals & Digital Branding

CASE 1: Google LLC v. Louis Vuitton Malletier (CJEU, 2010)

Issue:

Whether using trademarks as keyword advertising triggers constitutes infringement.

Principle:

The court held that:

• Google is not liable for trademark infringement merely for allowing keyword ads
• However, liability arises if ads create consumer confusion about origin

Relevance to AR festivals:

If an AR cultural platform or app:

• Uses “Kyiv Heritage Festival” as a keyword or tag
• Or allows advertisers to appear under similar names

👉 The key test becomes:
Does the digital environment mislead users into thinking there is official affiliation?

CASE 2: Interflora Inc. v. Marks & Spencer (UK, 2014)

Issue:

Use of competitor’s trademark in online advertising.

Principle:

• Even if trademark is used invisibly (SEO/ads), infringement occurs if it:
  • Affects origin recognition
  • Impairs brand distinctiveness

Relevance:

In AR cultural festivals:

• If a competitor festival appears in AR overlays near cultural monuments
• Or is suggested in digital curation feeds

👉 Risk arises when AR content blurs source identity of cultural events.

CASE 3: Tiffany & Co. v. eBay Inc. (US, 2010)

Issue:

Whether platforms are responsible for counterfeit trademark listings.

Principle:

• Platforms are not automatically liable
• Liability arises if they have knowledge of infringement and fail to act

Relevance:

For digital cultural curation platforms:

• If fake AR “Ukrainian Heritage Festival NFTs” are sold
• Or fake digital tickets circulate

👉 The platform must show:

• Notice-and-takedown systems
• Active brand protection measures

Otherwise, liability risk increases.

CASE 4: Hermès International v. Rothschild (MetaBirkins case) (US, 2023)

Issue:

NFTs depicting luxury handbags as artistic digital assets.

Principle:

• NFTs can still infringe trademarks
• Artistic expression defense is limited if there is consumer confusion or brand exploitation

Relevance to AR cultural festivals:

If someone creates:

• “Meta Kyiv Festival” NFTs
• AR replicas of Ukrainian cultural symbols under similar branding

👉 Even “artistic” AR content can violate trademark law if:

• It commercially exploits festival identity
• Confuses users about official cultural sponsorship

CASE 5: Adidas AG v. Thom Browne Inc. (US, 2023)

Issue:

Use of stripe designs resembling Adidas trademarks.

Principle:

• Even partial visual similarity can create infringement
• Especially in fashion/visual branding contexts

Relevance to AR festivals:

In AR environments:

• Visual overlays (flags, motifs, logos)
• Festival digital avatars or costumes

👉 Even non-identical but “confusingly similar” AR branding can infringe trademarks.

CASE 6: Louboutin v. Yves Saint Laurent (US & EU mixed jurisprudence, 2012 onward)

Issue:

Protection of color trademark (red sole shoe).

Principle:

• Single-color trademarks can be protected if they have strong brand association
• But only in specific contexts

Relevance:

For Ukrainian cultural festivals:

• Distinct visual identity elements (e.g., AR wheat-field gold overlay, embroidered patterns)
• Can be protected as non-traditional trademarks

👉 But only if they acquire distinctiveness in public perception.

4. Application to Ukrainian Hybrid Cultural Festivals

A Ukrainian AR cultural festival (physical + digital) may face trademark issues in:

A. AR overlays on monuments

If users scan Kyiv landmarks and see festival branding:

• Must ensure licensed trademark use
• Avoid third-party overlays mimicking official branding

B. Digital curation platforms

If a platform aggregates cultural content:

• Must avoid implying official sponsorship
• Must separate curated vs official festival marks

C. NFTs and digital collectibles

• Festival-branded NFTs require trademark clearance
• Risk of “Meta-festival” impersonation increases

D. Cross-border streaming/AR participation

Since AR festivals are global:

• EU/US trademark law may apply alongside Ukrainian law

5. Core Legal Tests Courts Apply

Across all cases, courts repeatedly use:

1. Likelihood of confusion test

Would an average user think:

“This AR experience is officially part of the Ukrainian festival?”

2. Dilution of brand identity

Even without confusion, is the cultural brand weakened?

3. Bad faith digital exploitation

Is someone using the festival’s reputation in AR or NFTs unfairly?

6. Key Takeaways

• Ukrainian law protects trademarks in both physical and digital contexts.
• AR and digital curation expand “use in commerce” into immersive environments.
• Courts rely heavily on EU/US precedent due to lack of AR-specific Ukrainian case law.
• The biggest legal risks are:
  • Digital impersonation
  • AR-based brand confusion
  • NFT misuse of cultural identity
  • Platform liability for curated content
