When applying for a patent in Hong Kong, many clients ask the same question: “Should I choose a short-term patent or a standard patent?”
Both have their own advantages and disadvantages, and their use cases are completely different. Choose wisely, and you’ll get effective protection at minimum cost. Choose poorly, and your core technology may be left vulnerable.
1. Key Differences at a Glance
| Aspect | Short-term Patent | Standard Patent (Re-registration) | Standard Patent (Original Grant) |
|---|---|---|---|
| Examination | Formal only | Formal only | Formal + Substantive |
| Grant Timeline | 4-6 months | 6-12 months | 2-3 years |
| Protection Term | 8 years | 20 years | 20 years |
| Rights Stability | Weaker (no substantive exam) | Strong (based on granted patent) | Strong (substantive exam) |
| Best For | Fast grant, short-cycle products | Core tech, long-term protection | Independent HK portfolio |
2. Short-term Patent: Best Use Cases
The biggest advantage of a short-term patent is speed — grant in as little as 4-6 months. However, it does not undergo substantive examination, so rights stability is relatively weaker.
Ideal for:
-
Technologies with a short life cycle (e.g., consumer electronics, fast-moving consumer goods packaging)
-
Situations requiring rapid protection before an exhibition or product launch
-
Budget-conscious applicants not yet ready to bear substantive examination fees
3. Standard Patent: Best Use Cases
Standard patents offer a 20-year term and strong rights stability. However, the grant timeline is longer, and re-registration standard patents require an underlying granted patent from China, Europe, or the UK.
Ideal for:
-
Core technologies and fundamental inventions
-
Products with a long life cycle (e.g., pharmaceuticals, mechanical manufacturing)
-
Fields where strong enforcement rights are essential
4. Practical Advice: A Combination Strategy
Many clients opt for a “short-term patent first, standard patent follow-up” combination strategy:
-
Stage 1: File a short-term patent application to quickly obtain a “patent pending” status
-
Stage 2: Within 6-12 months, evaluate market feedback and technical validation, then decide whether to proceed with a standard patent application
-
Stage 3: If the standard patent is granted, consider abandoning the short-term patent to save on annual fees
5. Our Recommendations
-
If your technology has a short life cycle and needs fast market validation: The short-term patent is the cost-effective choice
-
If your technology is a core barrier to entry requiring long-term protection: A standard patent is a necessary investment
-
If both conditions apply: The short-term + standard combination strategy balances speed and stability
