The short answer

Section 4 of the Industrial Design Act, 2023 excludes four kinds of design: purely technical or functional designs, designs whose use harms public order, morality or the environment, unregistered designs, and designs using national symbols. Check these before you spend on filing.

Sec 4
Exclusions
4
Excluded types
Registered
Only these protected
Look
Not function

Four designs the law does not protect

1

Purely functional

Shape dictated only by function, with no aesthetic aspect, such as a gear or an internal engine part. Design law protects look, not operation.

2

Harmful to the public

Designs contrary to decency, morality or environmental safety.

3

Unregistered

Without registration there is no exclusive right. The owner of an unregistered chair design cannot sue a copier under this Act.

4

National symbols

Designs including the national flag, coat of arms or state emblem of Bangladesh.

Before you file

  • Make sure the design is decorative, not only useful
  • Check it has not been shown or sold anywhere
  • Avoid state symbols and offensive content
  • Make sure the feature you want to protect is visible in the finished product

If a design is excluded here, another right may still help. A functional invention may suit a utility model, and a logo may be a trademark.

Excluded design questions

Can I protect how a product works with a design?

No. Use a patent or utility model instead.

Can I use the flag in a design?

No. State symbols are excluded.
