Most watch protection film on the market is cut from a generic pattern and sold under whichever brand name is printed on the packaging. FINX takes a different approach: the film's structure and the precision-cut shapes for specific watch series are registered as patents with China's National Intellectual Property Administration (CNIPA), under the patent holder Fine X Project.
Patents are public record. Anyone can look up the numbers below and confirm they are real, active registrations — that verifiability is the point of sharing them here.

A Utility Model Patent for the Film Structure
FINX holds a Chinese Utility Model Patent covering the structural design of its watch protection film:
- Patent name: A Watch Protection Film (一种手表保护膜)
- Patent No.: ZL 2025 2 2093147.6
- Publication No.: CN 224644451 U
- Patentee: Fine X Project (上海菲膜科技有限公司)
- Inventors: Boyang Ning, Yumin Liu
- Filed: September 28, 2025
- Granted: August 18, 2026
In China, a Utility Model Patent protects a product's structure or configuration and goes through formal examination by CNIPA rather than the full substantive novelty examination used for invention patents. It is a distinct, officially recognized category from a design patent or an invention patent — and it is the correct term for what this certificate covers.
Design Patents for Model-Specific Shapes
Beyond the film structure itself, FINX has also registered design patents protecting the precise outline of its protection film kits for three specific watch collections:
| Collection | Patent No. | Publication No. | Granted |
|---|---|---|---|
| Audemars Piguet series | ZL 2025 3 0568476.4 | CN 309904489 S | April 10, 2026 |
| Patek Philippe series | ZL 2025 3 0568472.6 | CN 309904488 S | April 10, 2026 |
| Richard Mille series | ZL 2025 3 0568490.4 | CN 309904490 S | April 10, 2026 |
A design patent protects the exact external shape of a product — in this case, the model-specific outline that lets a FINX kit align edge-to-edge with a particular case, bezel, and lug geometry rather than relying on a generic universal cut.
What This Means for Collectors
None of this replaces trying the product, but it does mean FINX's model-specific fit and film structure aren't just marketing language — they're documented with China's national patent authority, under patent numbers anyone can independently verify through CNIPA's public patent database.
For collectors comparing protection film brands, that's one more concrete thing to check beyond a seller's own claims about precision and fit.
