The Congress finds the following: 
(1) The Congress created a patent system to 
‘‘promote the Progress of Science and useful Arts, 
by securing for limited Times to Authors and Inven-
tors the exclusive Right to their respective Writings 
and Discoveries,’’ as provided for in the Constitution 
of the United States. 
(2) The Leahy-Smith America Invents Act 
(Public Law 112–29) enacted on September 16, 
2011, and several decisions of the Supreme Court 
have harmed the progress of Science and the useful 
Arts by eroding the strength and value of the patent 
system. 
(3) The United States Government exists to 
protect life, liberty, and property, which includes in-
tellectual property.

(4) A United States patent secures a private 
property right to an inventor. 
(5) This Act restores the patent system as envi-
sioned by the Constitution of the United States. 
SEC. 3. RESTORING THE RIGHT OF THE FIRST INVENTOR 
TO SECURE A PATENT. 
(a) REPEAL OF FIRST-TO-FILE SYSTEM UNDER THE 
AMERICA INVENTS ACT.—Section 3 of the Leahy-Smith 
America Invents Act (Public Law 112–29), including each 
amendment made by such section, is repealed and any 
amendment made by such section to any provision shall 
be effective as if the provision had not been amended by 
such section. 
(b) FIRST-TO-INVENT.—Notwithstanding any other 
provision under title 35, United States Code, a person 
shall be entitled to a patent where the inventor is first 
to conceive of the invention and diligently reduces the in-
vention to practice. 
(c) ONE-YEAR GRACE PERIOD.—Notwithstanding 
any other provision under title 35, United States Code, 
a person shall be entitled to a one-year grace period before 
filing an application for a patent, as the grace period ex-
isted before the date of the enactment of the Leahy-Smith 
America Invents Act under section 102 of title 35, United 
States Code, and with the same meaning of the terms ‘‘in

public use’’ and ‘‘on sale in this country’’ as interpreted 
before the enactment of the Leahy-Smith America Invents 
Act. 
(d) SENSE OF CONGRESS.—It is the sense of Con-
gress that— 
(1) reverting the United States patent system 
from a ‘‘first-to-file’’ system back to ‘‘first-to-in-
vent’’ system will promote the progress of science 
and the useful arts by securing for limited times to 
inventors the exclusive rights to their discoveries and 
incentivize innovation and protect inventors’ rights; 
(2) restoring the one-year grace period before 
the first and true inventor must file a patent appli-
cation on an invention will promote the progress of 
science and useful arts by enabling inventors once 
again to disclose inventions in order to attract in-
vestment, complete research and development on the 
invention, test, improve, and perfect the invention so 
as to improve the invention and the quality of the 
patent application; and 
(3) the repeal of section 3, and the amendments 
made by section 3, of the Leahy-Smith America In-
vents Act, restore sections 100, 102, 103, 135, and 
291 of title 35, United States Code, to the way such

sections read on the day before the date of the en-
actment of such Act. 
SEC. 4. ABOLISHING INTER PARTES AND POST-GRANT RE-
VIEW. 
(a) REPEAL OF INTER PARTES AND POST GRANT 
REVIEW.—Section 6 of the Leahy-Smith America Invents 
Act (Public Law 112–29), including each amendment 
made by such section, is repealed and any amendment 
made by such section to any provision shall be effective 
as if the provision had not been amended by such section. 
(b) REPEAL OF CODIFIED TITLES.—Chapters 31 and 
32 of title 35, United States Code, are repealed. 
(c) SENSE OF CONGRESS.—It is the sense of Con-
gress that— 
(1) inter partes review and post-grant review 
proceedings introduced by the Leahy-Smith America 
Invents Act have harmed the progress of science and 
the useful arts by subjecting inventors to serial chal-
lenges to patents; 
(2) inter partes review and post-grant review 
proceedings invalidate patents at an unreasonably 
high rate; 
(3) patent rights should be protected from un-
fair adjudication at the Patent and Trademark Of-

fice and duly issued patents should be adjudicated in 
a judicial proceeding; 
(4) repealing section 6 of the Leahy-Smith 
America Invents Act abolishes inter partes review, 
post-grant review, and the previously available inter 
partes reexamination proceedings; and 
(5) it is the intent of Congress to preserve ex 
parte reexamination proceedings under chapter 30 of 
title 35, United States Code. 
SEC. 5. ABOLISHING THE PATENT TRIAL AND APPEAL 
BOARD. 
(a) REPEAL
OF
PATENT

three members of the Board, who shall be designated by 
the Director. Only the Board of Patent Appeals and Inter-
ferences may grant rehearings. The Board shall not invali-
date an issued patent except in an ex parte reexamination 
under chapter 30. 
‘‘(c) AUTHORITY
OF
THE SECRETARY.—The Sec-
retary of Commerce may, in the Secretary’s discretion,

‘‘(d) DEFENSE TO CHALLENGE OF APPOINTMENT.— 
It shall be a defense to a challenge to the appointment 
of an administrative patent judge on the basis of the

that the administrative patent judge so appointed was act-
ing as a de facto officer.’’.

‘‘§ 141. Appeal to the Court of Appeals for the Federal 
Circuit 
‘‘(a) EXAMINATIONS.—An applicant dissatisfied with 
the decision in an appeal to the Board of Patent Appeals 
and Interferences under section 134 may appeal the deci-
sion directly to the United States Court of Appeals for 
the Federal Circuit, or may seek review de novo in any 
district court of the United States of competent jurisdic-
tion. 
‘‘(b) REEXAMINATIONS.—A patent owner who is, in

file a civil action under section 146, the decision appealed 
from shall govern the further proceedings in the case.’’. 
(e) SENSE OF CONGRESS.—It is the sense of Con-
gress that— 
(1) the Patent Trial and Appeal Board shall be 
replaced with the former Board of Patent Appeals

and post-grant review proceedings, the Patent Trial 
and Appeal Board is no longer needed to conduct 
these duties; 
(3) unless otherwise in the context of an ex 
parte reexamination under chapter 30 of title 35, 
United States Code, the Board of Patent Appeals 
and Interferences will not be used to invalidate an 
already issued patent; 
(4) the changes described in paragraphs (1) 
through (3) will protect the rights of patent owners 
who have been granted a patent and ensure a fair, 
fully adjudicated proceeding to invalidate an issued 
patent;

United States Code, reflects Congress’s intent to re-

(6) the amendments to section 134 of title 35, 
United States Code, and section 141 of title 35, 
United States Code, are intended to restore each re-
spective section to its prior state, but delete any ref-
erence to inter partes reexamination, which is no

SEC. 7. PATENTABILITY OF SCIENTIFIC DISCOVERIES AND 
SOFTWARE INVENTIONS. 
(a) AMENDMENT.—Section 101 of title 35, United 
States Code, is amended to read as follows: 
‘‘§ 101. Inventions patentable 
‘‘(a) IN GENERAL.—Whoever invents or discovers 
any new and useful process, machine, manufacture, or 
composition of matter, or any new and useful improvement 
thereof, may obtain a patent therefor, subject to the condi-
tions and requirements of this title.

invention as a whole, as understood by a person having

human mind.

determined without regard as to the requirements or con-
ditions of sections 102, 103, and 112 of this title, or the 
claimed invention’s inventive concept.’’. 
(b) SENSE OF CONGRESS.—It is the sense of Con-
gress that— 
(1) the Supreme Court’s recent jurisprudence 
concerning subject matter patentability has harmed 
the progress of science and the useful arts; 
(2) the United States patent system must pro-
tect and encourage research and development in 
such scientific disciplines as would promote the 
progress of science and the useful arts by securing 
for limited times to inventors the exclusive rights to 
their discoveries and provide scientists in the life 
sciences, computer sciences, and other disciplines, 
with certainty that their discoveries and inventions 
are entitled to patent protection; and 
(3) this amendment effectively abrogates Alice 
Corp. v. CLS Bank International, 134 S. Ct. 2347 
(2014) and its predecessors to ensure that life 
sciences discoveries, computer software, and similar 
inventions and discoveries are patentable, and that 
those patents are enforceable.

‘‘(b) DISCLOSURES IN PATENT APPLICATIONS AND

rectly or indirectly from the inventor or a joint in-
ventor; 
‘‘(2) the information disclosed to the Office or 
another party during the one-year period prior to 
the date of the application for patent had, before a 
patent application for the information was effectively 
filed, been publicly disclosed by the inventor or a 
joint inventor; or 
‘‘(3) the information disclosed and the claimed 
invention, not later than the effective filing date of 
the claimed invention, were owned by the same per-
son or subject to an obligation of assignment to the

(a) PRIVATE PROPERTY PATENT RIGHT.— 
(1) AMENDMENT.—Chapter 10 of title 35, 
United States Code, is amended by adding at the 
end the following new section: 
‘‘§ 106. Private property patent right 
‘‘A patent right is a private property right secured 
to an inventor upon issuance of the patent that shall only 
be revoked by a court ruling in a judicial proceeding, un-
less the patent owner consents to an administrative or 
other procedure.’’. 
(2) TECHNICAL
AND
CONFORMING
AMEND-
MENT.—The table of sections for chapter 10 of title 
35, United States Code, is amended by adding at 
the end the following new item: 
‘‘106. Private property patent right.’’. 
(b) OWNERSHIP; ASSIGNMENT.—Section 261 of title 
35, United States Code, is amended— 
(1) in the first sentence, by striking ‘‘patents 
shall have the attributes of personal property’’ and 
inserting the following: ‘‘patents shall be recognized

in whole or in part, including conveyance by assignment 
or license. Any successors, heirs, assigns, or licensees of 
a patent owner, who receive a lesser interest in a patent, 
shall be subject to any and all restrictions of their interest 
in the patent, provided that the successors, heirs, assigns, 
or licensees have actual or constructive notice of such re-
strictions.’’. 
(c) SENSE OF CONGRESS.—It is the sense of Con-
gress that— 
(1) recent jurisprudence of the United States 
Supreme Court, including Impression Products Inc. 
v. Lexmark International, Inc., have harmed the 
progress of science and the useful arts by limiting 
the ability of patent owners to exclude unlicensed 
customers from their supply chains; and 
(2) meaningful patent rights must permit pat-
ent owners to freely assign their rights in whole, or 
in part, and to ensure that successors, heirs, or as-
signs of a patent owner, or their assigns, are duly 
bound by restrictions or exclusions set by patent 
owners on the use of their property. 
SEC. 10. ENDING AUTOMATIC PUBLICATION OF PATENT AP-
PLICATIONS. 
(a) AMENDMENT.—Section 122(b) of title 35, United 
States Code, is amended to read as follows:

‘‘(b) PUBLICATION.— 
‘‘(1) IN GENERAL.—Each application for a pat-
ent shall be published, in accordance with procedures 
determined by the Director, only upon the request of 
the patent applicant. 
‘‘(2) INFORMATION RELEASED ONCE A PATENT 
ISSUES.—No information concerning a patent appli-
cation shall be available to the public unless and 
until a patent issues.’’. 
(b) SENSE OF CONGRESS.—It is the sense of Con-
gress that— 
(1) automatic publication of patent applications 
after 18 months has harmed the progress of science 
and the useful arts by creating ‘‘prior art’’ by oper-
ation of law that prevents a patent owner from ap-
plying for a patent on the same invention if a patent 
does not issue; and 
(2) automatic publication of patent applications 
encourages early disclosure of claimed inventions 
and subjects innovative inventions and discoveries 
reduced to practice in the United States to theft or 
appropriation by foreign competitors.

‘‘(1) PRESUMPTION OF VALIDITY FOR A PAT-
ENT.—In any judicial or administrative proceeding 
conducted in any court or Federal agency (as de-
fined in section 201) or of any State, a patent issued 
under this title shall be presumed valid. 
‘‘(2) PRESUMPTION OF VALIDITY FOR CLAIMS 
OF A PATENT.—In any proceeding described under 
paragraph (1)— 
‘‘(A) each claim of a patent (whether in 
independent, dependent, or multiple dependent 
form) shall be presumed valid independently of 
the validity of other claims; and 
‘‘(B) dependent or multiple dependent 
claims shall be presumed valid even though de-
pendent upon an invalid claim. 
‘‘(3) BURDEN OF ESTABLISHING INVALIDITY.— 
In any proceeding described under paragraph (1) in

Code, is amended by adding at the end the following: 
‘‘(d) TOLLING OF PATENT TERM DURING VALIDITY 
CHALLENGE.—In an action involving a patent where the 
validity of the patent has been challenged, the patent term 
shall be tolled from the time the validity of the patent is 
challenged to the time of resolution of the validity issue 
by the court. The patent term shall resume once the valid-
ity challenge is resolved. The court may award damages 
to the patent owner in a case in which another party 
brought a validity claim against the patent in bad faith.’’. 
SEC. 12. INJUNCTION. 
Section 283 of title 35, United States Code, is 
amended— 
(1) by striking ‘‘The’’ and inserting the fol-
lowing: to read as follows: 
‘‘(a) IN GENERAL.—The’’; and 
(2) by adding at the end the following new sub-
section: 
‘‘(b) PERMANENT INJUNCTION.— 
‘‘(1) IN GENERAL.—Upon a finding of infringe-
ment of a patent, the court shall presume that fur-
ther infringement of the patent would cause the pat-
ent owner irreparable harm. This presumption may

be overcome only by a showing of clear and con-
vincing evidence by the infringing party that the 
patent owner would not be irreparably harmed by 
further infringement of the patent. The patent 
owner is not required to make or sell a product cov-
ered by the patent to show irreparable harm. 
‘‘(2) PATENT OWNER DEFINED.—In this sub-
section, a ‘patent owner’ means the owner of the 
patent or an exclusive licensee of the patent.’’.

(Public Law 112–29), including each amendment made by 
such section, is repealed and any provision amended by 
such section shall be amended to read as in effect on the 
day before the date of the enactment of such Act.
