TechnologyLabor & Workplace

Summary

The U.S. Patent Office is proposing a new rule that would require foreign companies and individuals applying for patents to hire a U.S.-based patent lawyer or agent to represent them. This rule aims to ensure that the Patent Office can properly communicate with patent applicants and enforce U.S. patent laws.

Key Points

  • 1Foreign patent applicants would be required to hire a registered U.S. patent practitioner (lawyer or agent) to handle their patent applications instead of representing themselves
  • 2This rule applies to people and companies located outside the United States who want to patent their inventions in America
  • 3The requirement helps the Patent Office communicate more effectively and ensures applicants understand their legal obligations and deadlines
  • 4The public comment period runs from December 29, 2025 to January 29, 2026, allowing businesses and individuals to share their views before the rule becomes final
  • 5Foreign applicants who don't follow this rule could face rejection of their patent applications or legal complications with their patents
