Citation

Section 1 of act July 19, 1952, ch. 950, 66 Stat. 792, provided in part that this title may be cited as “Title 35, United States Code, section —.”

Separability

Section 3 of act July 19, 1952, ch. 950, 66 Stat. 815, provided that: “If any provision of Title 35, as enacted by section 1 hereof, is declared unconstitutional or is held invalid, the validity of the remainder of this title shall not be affected.”

Effective Date; Savings Provision

Section 4 of act July 19, 1952, ch. 950, 66 Stat. 815, provided that:

“(a) This Act [enacting this title] shall take effect on January 1, 1953 and shall apply to all applications for patent filed on or after such date and to all patents granted on such applications. It shall apply to further proceedings on applications pending on such date and to patents granted on such applications except as otherwise provided. It shall apply to unexpired patents granted prior to such date except as otherwise provided.

“(b) Section 102 (d) of Title 35, as enacted by section 1 hereof, shall not apply to existing patents and pending applications, but the law previously in effect, namely the first paragraph of R. S. 4887 [first paragraph of section 32 of former Title 35], shall apply to such patents and applications.

“(c) Section 119, second paragraph, of Title 35 as enacted by section 1 hereof shall not apply to existing patents.

“(d) The period of one year specified in section 102 (b) of Title 35 as enacted by section 1 hereof shall not apply in the case of applications filed before August 5, 1940, and patents granted on such applications, and with respect to such applications and patents, said period is two years instead of one year.

“(e) Nothing contained in Title 35, as enacted by section 1 hereof, shall operate to nullify any judicial finding prior to the effective date of this Act on the validity of any patent by a court of competent jurisdiction.

“(f) Nothing in Title 35, as enacted by section 1 hereof, shall affect any provision of the Atomic Energy Act of 1946 (Aug. 1, 1946, ch. 724, 60 Stat. 755) [§ 2011 et seq. of Title 42, The Public Health and Welfare].

“(g) The period of one year specified in section 4 of Title 35 as enacted by section 1 hereof shall not apply in the case of applications filed before the effective date of this Act.

“(h) The repeal of sections 1–9, 11, 12 of the Act of Congress approved February 1, 1952 (ch. 4, 66 Stat. 3) [sections 151 to 159 of former Title 35], shall not affect any rights or liabilities existing on the date of approval of this Act [July 19, 1952]. An order of secrecy issued under or in effect under the repealed Act and in effect on the date of approval of this Act, shall be considered as issued under this Act, and any claims arising under the repealed Act or subject to presentation and determination pursuant thereto and unsettled as of the effective date of this Act, may be presented and determined pursuant to the provisions of this Act [this title].”

Repeals

Section 5 of act July 19, 1952, ch. 950, 66 Stat. 815, repealed the sections or parts of sections of the Revised Statutes or Statutes at Large codified in this Act with the proviso that “Any rights or liabilities now existing under such sections or parts thereof shall not be affected by this repeal.”

The table below lists the classification updates, since Jan. 3, 2012, for the contained sections. If there are multiple sections, they are presented in section number order (original document order).

The most recent Classification Table update that we have noticed was Wednesday, December 26, 2012

An empty table indicates that we see no relevant changes listed in the classification tables. If you suspect that our system may be missing something, please double-check with the Office of the Law Revision Counsel.

How To Use

Multiple entries for a section are listed most recent first, within the section.

The Session Year indicates which session of Congress was responsible for the changes classified. The Congress number forms the first part of the Public Law number; each Congress has two sessions.

Abbreviations used in the Description of Change column:

An empty field implies a standard amendment.
"new" means a new section or new note, or all new text of an existing section or note.
"nt" means note.
"nt [tbl]" means note [table].
"prec" means preceding.
"fr" means a transfer from another section.
"to" means a transfer to another section.
"omitted" means the section is omitted.
"repealed" means the section is repealed.
"nt ed change" and "ed change" - See the Editorial Classification Change Table [pdf].

The Public Law field is linked to the development of the law in the Thomas system at the Library of Congress.

The Statutes at Large field is linked to the text of the law, in the context of its volume of the Statutes at Large, at the Government Printing Office. Please note that it takes a while for these pages to get posted, so for very recent legislation, you need to look at the "enrolled" version at the Thomas site.

The Statutes at Large references have been rendered in the format used as page numbers in the Public Law web pages to which we link, to facilitate copy-paste into browser "find on this (web) page" tools. We are still working on a more direct link facility.

For serious comparison work, we suggest copying all or a portion of the Public Law text into your favorite text editor, for convenient content traversal and window control.

Sections with change type "new" are a special case, still under development. All are now listed, at the title level only.

You will find that occassionally a specific update you notice in a Public Law listed in a classification table will already have made it into the Code. We assume this is an artifact of the LRC edit process. The LII does not edit the LRC content.

You can look for information about what it is and is not, which titles are positive law, the schedule of Supplements, etc. Under download you can find the source data we use here (GPO locator files), as well as, PDF files that look just like the paper books (these may be rather large).

Refer to the Thomas site for changes that have not yet made it into the classification tables.
