Patent vs Trademark: What's the Difference?

한눈에 보기

Patents protect inventions — novel processes, devices, or compositions. Trademarks protect brand identity — names, logos, and slogans that distinguish your goods and services. Most businesses need trademark protection; patent protection is valuable when you have a genuinely novel technical invention worth defending.

Patent 선택 시

You have invented a novel device, process, or composition that competitors could copy
You want to prevent others from using your technical innovation for 20 years
You plan to license your invention as a revenue stream
You are in a technology or biotech space where IP is a primary competitive moat

Trademark 선택 시

You are launching a brand with a name or logo you want to protect exclusively
You want to prevent competitors from using similar names in your industry
You are investing in building brand recognition and need legal protection for it
You want to enforce your brand rights against infringers nationally or internationally

결론

Most businesses should start with trademark protection — it is faster, cheaper, and protects the brand you are actively building. Patents are valuable when you have a genuinely novel technical invention and the resources to enforce the patent against infringement. An IP attorney can help you prioritize which filings to pursue first given your budget and business model.
