On March 19, 2013 certain individuals and organizations were allowed to file and pay patent fees as a "micro entity". In general, micro entities are inventors or small organizations with a gross income less than $169,548 and who have not filed more than four patent applications in the past.
Save over $3,900
Micro entity applicants can save over $3,900 during the life of an average patent. Most USPTO fees are reduced by 75% for those who qualify. If you do not qualify as a micro entity, ask your patent attorney about filing as a small entity instead.
