What Is a Design Right?

A design right protects the visual appearance (shape, pattern, color, or their combination) of articles, buildings, and interiors (Design Act Article 2(1)). It prevents competitors from copying a product's appearance.

Protection lasts 25 years from the filing date (Article 21(1)).

2020 Reform: Expanded Scope

The amended Design Act (effective April 2020) significantly broadened protectable subject matter:

New CategoryScope
Building designsExterior and interior of buildings
Interior designsOverall interior of stores, offices, etc.
Screen/GUI designsOperating interfaces, icons

Notably, GUI designs now extend to images in the cloud not stored on a physical article.

Registration Requirements

Registration requires (Article 3): 1. Industrial applicability: capable of mass production 2. Novelty: not publicly known or worked before filing 3. Non-obviousness: not easily created by a person skilled in design 4. No grounds for non-registration (Article 5): e.g., functional shapes only, public order violations

Grace Period (Article 4)

Filing within 1 year of public disclosure at an exhibition preserves novelty.

Procedure and Costs

ItemCost
Filing fee (JPO)¥16,000 per design
Registration fee (years 1–3)¥8,500/year
Patent attorney fees¥150,000–400,000

Examination typically takes 6–12 months.

Scope of Rights: Similarity

A design right owner has exclusive rights to work the registered design and designs similar to it commercially (Article 23).

Similarity is judged from the perspective of a consumer's visual impression. If the dominant visual impression is the same or similar, infringement is established.

Partial Designs

Only the distinctive part of a product can be registered (Article 2(1)). For example, only the corner design of a smartphone.

Related Designs

Designs similar to the principal design can be registered as related designs (Article 10), filed within 10 years of the principal design's filing date. A family of related designs creates a broader rights network.

Summary

Design rights powerfully protect product appearance from copying. The 2020 reform made them essential for digital product companies by covering GUIs and interior spaces. Combining partial designs and related designs into a rights family is the cornerstone of effective design IP strategy.
