What the claims cover, in plain language
Claim 1 - defines the core structure: a backpack body with four extension holes and Velcro at the inner bottom, plus Velcro on the inner side. A head extension opening on one side has an elastic cord lock. A soft pad is included, which can attach to either the side or bottom Velcro. When attached to the bottom, it covers the extension holes.
Claim 2 - specifies an internal nylon rope at the corner of the side/bottom, ending in a loop buckle for securing the pet. Claim 3 - describes a heart-shaped opening on the front, lined with breathable gauze. Claim 4 - details the carrying system: single shoulder strap, two waist belts, connected by a rope strap passing through metal rings and secured by buckles. Claim 5 - adds rubber sleeves on the rope strap sections passing through the buckles. Claim 6 - includes a pocket on the first waist belt with a cover cloth. Claim 7 - includes a pocket on the shoulder strap with a cover cloth, connected to the body via a snap buckle. Claim 8 - describes fastening straps on the back opposite the shoulder strap, connecting to snaps on the body.

What this means for US production
This patent was filed only in China and is currently in force. Making or selling this specific design in China requires the owner’s permission. However, since there are no US or foreign family members, the patent does not directly restrict manufacturing or sales in the United States under this specific IP right.
Two points to settle early:
- Other patents may exist. Pet carriers are a competitive field with many existing US patents regarding harnesses, ventilation structures, and safety latches. A freedom-to-operate (FTO) review is strongly recommended before tooling, focusing on the cord-lock mechanism and the modular pad attachment system.
- Safety Standards Compliance. The design involves restraint mechanisms (internal tether) and openings. These features interact with safety standards for pet products, particularly regarding entanglement risks and structural failure points.
Customization and manufacturing
What can be customized
| Area | Options |
|---|---|
| Fabric Material | Oxford cloth, nylon, polyester; water-resistant coatings |
| Pad Design | Thickness of foam, shape of Velcro patches, fabric texture |
| Cord Lock | Color, size, tension strength of the elastic mechanism |
| Strap Configuration | Width of shoulder/waist straps, padding density, buckle types |
| Window Shape | Heart-shape is specified in claims, but alternative geometric shapes with mesh are possible if avoiding Claim 3 infringement |
| Tether Length | Adjustable length of internal nylon rope |
Things to plan for (US market)
- CPSC Guidelines: While there is no specific federal mandatory standard for pet backpacks, general consumer product safety rules apply. Ensure cords and straps do not create strangulation hazards for children or pets.
- California Prop 65: Screen fabrics, dyes, and plastic buckles for restricted chemicals like phthalates and lead.
- ASTM F963 (Toy Safety): If marketed alongside toys or for very young handlers, check applicability, though usually excluded as a pet product.
- Labeling Requirements: Care labels (fiber content, washing instructions) and country of origin labeling are mandatory.
How a project runs
- Inquiry - Define target pet size, material preferences, and quantity.
- Design Adaptation - Modify dimensions, select compatible fabrics, ensure cord lock meets safety pull-test requirements.
- Prototype - Create samples to test Velcro adhesion strength, cord lock ease-of-use vs. pet resistance, and tether durability.
- Pilot Run - Conduct drop tests, abrasion tests, and wash tests on materials.
- Production - Cutting, sewing, hardware installation, quality control checks on stitching and buckle function.
Quantities & timeline
The product relies heavily on sewing and assembly rather than injection molding, though custom cord locks and buckles may require tooling if unique designs are chosen. Standard hardware can be sourced from existing suppliers. Lead times depend on fabric sourcing and sample approval cycles.
