Micro entity status
Micro entity receive a 75% reduction of fees. As of today, the standard minimum fee, paid by large entities, when a new utility patent application is filed, is US$1,600.00. For the same application, a small entity pays only US$800.00. A qualifying micro-entity will pay, according to today's fee schedule, only US$400.00.
A micro entity is any applicant that:
Qualifies as a small entity
Has not been named as an inventor on more than 4 previously-filed applications.
Does not include foreign applications, provisionals, or international applications where basic national fee was not paid.
Applications from prior employment (which were assigned/under an obligation to assign) don’t count.
Did not, in calendar year before paying fee, have a gross income exceeding 3 times median household income for that preceding calendar year, as most recently reported by the Bureau of the Census. (Currently about $150k)
Not be under an obligation to assign, grant, or convey a license or other ownership to another entity that does not meet the same income requirements as the inventor.
U.S. Institutions of Higher Education also qualify as micro entities.
