Patent or Utility Model: Which One Fits Your Invention?

Türkiye protects inventions through two instruments: patents and utility models. On the surface they look interchangeable, but they differ sharply in scope, duration, cost and litigation strength.

Inventive step: the dividing line

Patents require both novelty and inventive step. Utility models require only novelty. That allows some inventions to qualify for utility-model protection even if they wouldn’t pass the inventive-step bar. But choosing utility model when an invention does pass that bar leaves the strongest weapon in the holster.

Duration and cost

Patents last 20 years from filing; utility models 10. Utility models register faster and cost less up front, but patents are stronger in litigation. Short-lifecycle, easily-copied products may favour utility models; long-lifecycle, strategic technologies almost always favour patents.

A practical matrix

• Inventive step uncertain + short economic life → utility model
• Clear inventive step + long market → patent
• Fast-to-market niche product → utility model (with optional later patent)
• International licensing ambitions → patent
