Patent vs Trademark: What's the Difference?
Câu trả lời nhanh
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.

Kết luận
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.
