How does a design patent application differ from a utility patent application?

Design patent applications and utility patent applications are distinct types of patent applications, each protecting different aspects of an invention. According to MPEP 201:

‘Design applications are not included in the term ‘nonprovisional’ as used in 37 CFR 1.9. […] Design applications are treated separately in 35 U.S.C. 171-173 and 37 CFR 1.151-1.155.’

Key differences include:

• Subject Matter: Utility patents protect how an invention works, while design patents protect how it looks.
• Duration: Utility patents last 20 years from filing, design patents 15 years from grant.
• Examination Process: Design applications typically have a simpler examination process.
