Лист за преговор: Mastering Trademark Law Essentials

Trademark Law Revision Sheet

1. 📌 Essentials

• Trademark: Sign capable of graphical representation used to distinguish goods/services.
• Functions: Identify origin, guarantee quality, promote brand.
• Absolute grounds for refusal: Lack of distinctiveness, descriptiveness, deception.
• Relative grounds for refusal: Prior rights, reputation, unfair advantage.
• Likelihood of confusion: risk of consumers mistaking one mark for another.
• Reputable trademarks: Well known, recognized by significant public segment.
• Legal sources: Trademark Directive 2015/2436, CJEU case law.
• Infringement: Use of identical or similar signs for same/similar goods causing confusion or link.
• Similarity assessment: Visual, phonetic, conceptual.
• Goods/services assessment: Nature, end users, competition, complementarity.
• Exceptions to specialty: Use of reputation for different goods/services if unfair.
• Reputed markers can obstruct similar signs even if not identical.
• Prior rights typically do not include patents.
• Reputation can be territorial and time-dependent.
• Signs are identical if same or minor differences; similar if close.
• Confusion likelihood depends on consumer perception, familiarity, and sign similarity.
• Legal standards from Sabel, Canon, Lloyd, Arsenal cases.

2. 🧩 Key Structures & Components

• Trademark — Sign representing goods/services.
• Distinctiveness — Key for registration; can be inherent or acquired.
• Reputation — Recognition by substantial part of public.
• Prior trademarks — Existing rights that can block registration.
• Sign types — Word marks, logos, slogans, shapes.
• Legal grounds — Absolute (e.g., lacking distinctiveness) and relative (e.g., prior rights).
• Infringement — Use of similar or identical signs causing confusion or unfair advantage.
• Assessment criteria — Sign similarity, goods similarity, consumer perception.
• Legal sources — European Directive and case law.

3. 🔬 Functions, Mechanisms & Relationships

• Sign registration depends on meeting criteria of distinctiveness and legality.
• Assessment of confusion considers similarity of signs and goods, plus consumer perception.
• Reputation enhances protection; a well-known mark can prevent similar signs even on non-identical signs.
• Absolute grounds reject signs lacking function or being deceptive.
• Relative grounds prevent confusingly similar marks infringing prior rights.
• Likelihood of confusion arises when consumers link signs/products from the same origin.
• Reputation can extend protection territorially and temporally.
• Unfair advantage occurs if a sign links or damages a famous mark without consent.
• Legal cases (Sabel, Canon, Lloyd, Arsenal) establish principles.
• Exceptions to restrictions include using a famous mark’s reputation for different goods if not harmful or unfair.

Item	Key Features	Notes / Differences
Absolute grounds	Not distinctive, descriptive, deceptive	Block registration before approval
Relative grounds	Prior rights, reputation, unfair advantage	Affect existing trademarks or well-known marks
Sign similarity	Visual, phonetic, conceptual	Assessed collectively in context
Goods similarity	Nature, end use, consumer target, competition, complementarity	Influences confusion risk
Reputed trademarks	Known by substantial part, within territory, over time	Provides broader protection
Infringement scope	Same or similar signs, causing confusion or linking	Includes unfair advantage

6. ⚠️ High-Yield Pitfalls & Confusions

• Confusing "similarity" with "identity" — not always identical signs are infringing.
• Overestimating the scope of patent rights in trademark disputes.
• Underestimating the significance of consumer perception.
• Assuming reputation provides automatic, unlimited protection.
• Mixing absolute and relative grounds without proper legal basis.
• Overlooking the territorial and temporal limits of reputation.
• Misjudging the effects of using a famous mark for different goods.
• Ignoring the legal case law guiding interpretation.
