On August 24, 2009, the US Patent and Trademark Office issued Interim Examination Instructions For Evaluating Subject Matter Eligibility Under 35 U.S.C. §101. 

This Omnilaw app helps you work through the flowchart to test your patent claims for subject matter eligibility under these interim examination instructions.

The USPTO is issuing the Interim Eligibility Instructions and has begun the process of training examiners on these instructions to reduce the delay in delivering these instructions to examiners, but the USPTO desires the benefit of public comment on the instructions and will revise the guidelines as appropriate based on comments received.
