Patent Eligibility Restoration Act of 2022
This bill amends the law relating to patent subject matter eligibility to establish that only specified subject matter (e.g., a natural process wholly independent of human activity) are ineligible for patenting. (Currently, subject matter eligibility is determined by examining whether the claimed invention is directed to certain ineligible categories, and if so, whether there is an inventive concept.)
To amend title 35, United States Code, to address matters relating to 
       patent subject matter eligibility, and for other purposes.

    Be it enacted by the Senate and House of Representatives of the 
United States of America in Congress assembled,

SECTION 1. SHORT TITLE.

    This Act may be cited as the ``Patent Eligibility Restoration Act 
of 2022''.

                if that process is embodied in a machine or 
                manufacture, unless that machine or manufacture is 
                recited in a patent claim without integrating, beyond 
                merely storing and executing, the steps of the process 
                that the machine or manufacture perform.
                    ``(B) Human genes and natural materials.--For the

                a subject of the action is eligible for a patent under 
                this section, including on motion of a party when there 
                are no genuine issues of material fact.
