Semantic Notes
The word has three distinct but related core meanings: the legal right (noun), the quality of being obvious (adjective), and the act of securing the right (verb). The adjective meaning relates to visibility and clarity, not legal rights.
Dialectal Variation
British vs American Usage
Differences
Pronunciation is the primary difference. In BrE, the first syllable sounds like 'pay'; in AmE, it sounds like 'pat'. The legal/technical meanings are identical.
Connotations
In both, the adjective 'patent' can sound formal or slightly old-fashioned when meaning 'obvious'.
Frequency
The noun (legal) is common in business/tech contexts. The adjective (obvious) is less frequent and more literary/formal.

Common Pitfalls
Translation Traps (for Russian speakers)
- Do not confuse with Russian 'патент' which is a direct borrowing but used more narrowly for certain trade licences or work permits.
- The adjective meaning 'obvious' has no direct single-word Russian equivalent; use 'очевидный', 'явный'.
Common Mistakes
- Using 'patent' as a verb without an object (Incorrect: 'They patented.' Correct: 'They patented the process.').
- Confusing 'patent' (adjective) with 'patently' (adverb) - 'It was patent falsehood' vs. 'It was patently false'.
- Misspelling as 'patant' or 'patient'.
