Assessing Trademark Phonetic Similarity Under Nepalese Practice

The standard: not science, but not guesswork

There is no phonetic algorithm in the PDTA. The assessment mirrors how deceptive similarity is judged everywhere: the ordinary consumer, recalling the name imperfectly, deciding whether two marks are the same brand. Imperfect recall is the point — people remember sounds and shapes of words, not spellings, which is why sound-alike conflicts survive even side-by-side comparison on paper.

In Nepal the consumer test runs bilingually. A name coined in Nepali is spoken with Nepali phonology — aspirated consonants, retroflex sounds, vowel length — and then often written down in English by someone guessing at the spelling. Both renderings are live on the register, which is why phonetic screening has to cover both pronunciations and both scripts.

• The test is imperfect auditory recall by the ordinary consumer, not letter-by-letter comparison
• Nepali phonology (aspiration, vowel length) generates its own variant families
• The same name can be registered in several spellings — they are one mark commercially

The variant families that generate conflicts

Practice across thousands of published records shows conflicts clustering in a small set of transformation families. Screening a name against its own family members catches most of the phonetic field.

A working method for testing similarity

Run the assessment in a fixed order so conclusions are repeatable and documented — the same order an examiner and an opposition panel effectively follow.

1. 1

   Identify the dominant element

   Which syllable or word carries the brand? In PHOOLCHAND TRADERS it is PHOOLCHAND, not TRADERS. Similarity is weighed on dominant elements first.

2. 2

   Compare the openings

   First syllables carry the most weight in recall — marks that begin differently are more easily distinguished than marks that end differently.

3. 3

   Say them aloud, both ways

   Pronounce each mark in English and in Nepali. If you would transcribe two different spellings the same way, they are phonetically close.

4. 4

   Weigh the overall impression

   Length, rhythm and visual shape matter: a two-syllable name has fewer places to hide differences than a five-syllable one.

5. 5

   Apply class and goods overlap

   Similarity becomes a conflict only with overlapping goods or services (Section 18A). A sound-alike in a distant class is a note; in your class, a threat.

6. 6

   Document the conclusion

   Record the variants screened, the hits found, and the judgment call. The note is cheap; re-doing clearance after an opposition arrives is not.

Similarity in practice: refusal and opposition

Phonetic similarity surfaces at three moments: examination (the Department objects under Section 18(1)), opposition (a third party challenges your published application), and the market (confusion that neither office caught). The first two are tractable with screening; the third is what the screening is for.

When a close call arises — genuinely arguable similarity, defensible either way — the decision input is commercial, not linguistic: how much is the name worth, how litigious is the other side, and what would rebranding cost at this stage? That is the point to spend an adviser's hour, not before.
