Utility Patent vs Design Patent – Differences

A utility patent protects the functionality of the invention, whereas a design patent protects the appearance of the Invention. Some of the differences are explained below in detail.

The scope of a design patent is limited to only the ornamental appearance of an invention, whereas the scope of utility patent lies around the function or structure of an invention. Also, a utility patent can protect many different variations of a product using a single utility patent, whereas design patent can only claim for a single clause i.e. appearance.

  • The cost incurred:

Since utility patents cover a broader scope of protection, the cost incurred in utility patents is much higher than design patents. Even for hiring attorneys and professionals for consultation, utility patent applications cost way too far than design patents. Moreover, Utility patent requires maintenance fees, you must pay it at the 4th, 8th and 12th year after the paid was issued. While, there is no clause for any such fees to be paid, for design patents after once it gets issued.

  • Average processing time: 

The average pending time for a utility patent is 25.6 months, while it is 1-3 years for a design patent.

  • Rejection probability:

Utility-based patents work on a broader scope due to which its probability of initial rejection is approximately 80-90%. On the other hand, design-based patents cover only the claims for appearance, its rejection probability lies very close to negligibility.

  • Application process time:

Utility patents cover broader aspects and hold a higher rate of rejection and therefore, they possess a longer application process in comparison with the design patent application.
