Intellectual property

Intellectual property are law property over creations of the mind, both artistic and commercial, and the corresponding fields of law.

Furthermore, the law
LAW

LAW may refer to:* Anti-tank warfare, e.g. the US Army M72 LAW or the British Army LAW 80*Palestinian Society for the Protection of Human Rights ...
s of various countries define the scope of the public domain differently, making it necessary to specify which jurisdiction's public domain is being discussed.

The public domain is most often discussed in contrast to works whose use is restricted by copyright
Copyright

Copyright is a form of intellectual property which gives the creator of an original work exclusive rights for a certain time period in relation to that work, including its publication, distribution and adaptation; after which time the work is said to enter the public domain....
. Under modern law, most original works of art, literature, music, etc. are covered by copyright from the time of their creation for a limited period of time (which varies by country). When the copyright expires, the work enters the public domain. It is estimated that currently, of all the books found in the world's libraries, only about 15% are in the public domain, even though only 10% of all books are still in print; the remaining 75% are books which remain unavailable because they are still under copyright protection.

The public domain can also be defined in contrast to trademark
TradeMark

s. Names, logos, and other identifying marks used in commerce can be restricted as proprietary trademarks for a single business to use. Trademarks can be maintained indefinitely, but they can also lapse through disuse, negligence, or widespread misuse, and enter the public domain. It is possible, however, for a lapsed trademark to become proprietary again, leaving the public domain.

The public domain also contrasts with patent
Patent

A patent is a set of exclusive rights granted by a state to an inventor or his assignee for a term of patent in exchange for a disclosure of an invention....
s. New inventions can be registered and granted patents restricting others from using the inventions without permission from the inventor. Like copyrights, patents last for a limited period of time, after which the inventions covered by them enter the public domain and can be used by anyone.

No legal restriction on use

A creative work is said to be in the public domain if there are no laws which restrict its use by the public at large. For instance, a work may be in the public domain if no laws establish proprietary

 rights over the work, or if the work or its subject matter are specifically excluded from existing laws.

Although "intellectual property" laws are not designed to prevent facts from entering the public domain, collections of facts organized or presented in a creative way, such as categorized lists, may be copyrighted. Collections of data with intuitive organization, such as alphabetized directories like telephone directories, are generally not copyrightable. In some countries copyright-like rights are granted for databases, even those containing mere facts.

Work of the United States Government

A work of the United States government, as defined by United States copyright law, is "a work prepared by an officer or employee of the Federal government of the United States as part of that person's official duties." The term only applies to the work of the federal government, not state or local governments....
 and various other governments are excluded from copyright law and may therefore be considered to be in the public domain in their respective countries. They may also be in the public domain in other countries as well. "It is axiomatic that material in the public domain is not protected by copyright, even when incorporated into a copyrighted work."

Since 1978
A work that is created (fixed in tangible form for the first time) after January 1, 1978, is automatically protected from the moment of its creation and is given a term lasting for the author’s life, plus an additional 70 years after the author’s death. In the case of “a joint work prepared by two or more authors who did not work for hire,” the term lasts for 70 years after the last surviving author’s death. For works made for hire, and for anonymous and pseudonymous works (unless the author’s identity is revealed in Copyright Office records), the duration of copyright will be 95 years from first publication or 120 years from creation, whichever is shorter.

Before 1978, unpublished works were not covered by the federal copyright act. Rather, they were covered under (perpetual) common law

, effective 1978, abolished common law copyright in the United States so that all works, published or unpublished, are now covered by federal statutory copyright, with the exception of sound recordings fixed before February 15, 1972. The claim that "pre-1923 works are in the public domain" is correct only for published works; unpublished works are under federal copyright for at least the life of the author plus 70 years. For a work made for hire, the copyright in a work created before 1978, but not theretofore in the public domain or registered for copyright, subsists from January 1, 1978, and endures for a term of 95 years from the year of its first publication, or a term of 120 years from the year of its creation, whichever expires first. If the work was created before 1978 but first published 1978–2002, the federal copyright will not expire before 2047.

 Implementation Act of 1988, the lack of a proper copyright notice would place an otherwise copyrightable work into the public domain, although for works published between January 1, 1978 and February 28, 1989, this could be prevented by registering the work with the Library of Congress

 within five years of publication. After March 1, 1989, an author's copyright in a work begins when it is fixed in a tangible form; neither publication nor registration is required, and a lack of a copyright notice does not place the work into the public domain.

1964 to 1977
Works published with notice of copyright or registered in unpublished form in the years 1964 through 1977 automatically had their copyrights renewed for a second term.

Before 1964
Works published with notice of copyright or registered in unpublished form on or after January 1, 1923, and prior to January 1, 1964, had to be renewed during the 28th year of their first term of copyright to maintain copyright for a full 95-year term.

With the exception of maps, music, and movies, the vast majority of works published in the United States before 1964 were never renewed for a second copyright term.

Sound recordings
Very few sound recordings are in the public domain in the United States. Sound recordings fixed in a tangible form before February 15, 1972, were generally covered by common law or in some cases by anti-piracy statutes enacted in certain states, not by federal copyright law, and the anti-piracy statutes typically have no duration limit. The 1976 Copyright Act, effective 1978, provides federal copyright for unpublished and published sound recordings fixed on or after February 15, 1972. Recordings fixed before February 15, 1972, are still covered, to varying degrees, by common law or state statutes. Any rights or remedies under state law for sound recordings fixed before February 15, 1972, are not annulled or limited by the 1976 Copyright Act until February 15, 2067. On that date, all sound recordings fixed before February 15, 1972, will go into the public domain in the United States.

For sound recordings fixed on or after February 15, 1972, the earliest year that any will go out of copyright and into the public domain in the U.S. will be 2043, and not in any substantial number until 2048. Sound recordings fixed and published on or after February 15, 1972, and before March 1, 1989, which did not carry a proper copyright notice on the recording or its cover entered the public domain on publication, although from 1978 onward the owners of the copyrights had up to five years to remedy this omission and reclaim the copyright.

Laws of Canada, Australia, and other Commonwealth nations

These numbers reflect the most recent extensions of copyright in the United States and Europe. Canada and New Zealand have not, , passed similar twenty-year extensions. Consequently, their copyright expiry times are still life of the author plus 50 years. Australia passed a 20-year copyright extension in 2004, but delayed its effect until 2005, and did not make it revive already-expired copyrights. Hence, in Australia works by authors who died before 1955 are still in the public domain.

, a work would enter the public domain with respect to copyright if it was released without a copyright notice. This was true prior to March 1, 1989 (), but is no longer the case. Any work (of certain, enumerated types) receives copyright as soon as it is fixed in a tangible medium.

It is commonly believed by non-lawyers that it is impossible to put a work into the public domain. Although copyright law generally does not provide any statutory means to "abandon" copyright so that a work can enter the public domain, this does not mean that it is impossible or even difficult, only that the law is somewhat unclear. Congress may not have felt it necessary to codify this part of the law, because abandoning property (like a tract of land) to the public domain has traditionally been a matter of common law, rather than statute. (Alternatively, because copyright has traditionally been seen as a valuable right, one which required registration to achieve, it would not have made sense to contemplate someone abandoning it in 1976 and 1988.)

Statutory law

Computer Software Rental Amendments Act
There are several references to putting copyrighted work into the public domain. The first reference is actually in a statute passed by Congress, in the Computer Software Rental Amendments Act of 1990 (Public Law 101–650, 104 Stat. 5089 (1990)). Although most of the Act was codified into Title 17 of the U.S. Code, there is a very interesting provision relating to "public domain shareware" which was not, and is therefore often overlooked.

Sec. 805. Recordation of Shareware
(a) IN GENERAL— The Register of Copyrights is authorized, upon receipt of any document designated as pertaining to computer shareware and the fee prescribed by section 708 of title 17, United States Code, to record the document and return it with a certificate of recordation.
(b) MAINTENANCE OF RECORDS; PUBLICATION OF INFORMATION— The Register of Copyrights is authorized to maintain current, separate records relating to the recordation of documents under subsection (a), and to compile and publish at periodic intervals information relating to such recordations. Such publications shall be offered for sale to the public at prices based on the cost of reproduction and distribution.
(c) DEPOSIT OF COPIES IN LIBRARY OF CONGRESS— In the case of public domain computer shareware, at the election of the person recording a document under subsection (a), 2 complete copies of the best edition (as defined in section 101 of title 17, United States Code) of the computer shareware as embodied in machine-readable form may be deposited for the benefit of the Machine-Readable Collections Reading Room of the Library of Congress.
(d) REGULATIONS— The Register of Copyrights is authorized to establish regulations not inconsistent with law for the administration of the functions of the Register under this section. All regulations established by the Register are subject to the approval of the Librarian of Congress.


One purpose of this legislation appears to be to allow "public domain shareware" to be filed at the Library of Congress

, presumably so that the shareware would be more widely disseminated. Therefore, one way to release computer software into the public domain might be to make the filing and pay the fee. This could have the effect of "certifying" that the author intended to release the software into the public domain. It does not seem that registration is necessary to release the software into the public domain, because the law does not state that public domain status is conferred by registration. Judicial rulings supports this conclusion, see below.

By comparing paragraph (a) and (c), one can see that Congress distinguishes "public domain" shareware as a special kind of shareware. Because this law was passed after the Berne Convention Implementation Act of 1988, Congress was well aware that newly-created computer programs (two years worth, since the Berne Act was passed) would automatically have copyright attached. Therefore, one reasonable inference is that Congress intended that authors of shareware would have the power to release their programs into the public domain. This interpretation is followed by the Copyright Office in .

Berne Convention Implementation Act

The Berne Convention Implementation Act of 1988 states in section twelve that the Act "does not provide copyright protection for any work that is in the public domain." The congressional committee report explains that this means simply that the Act does not apply retroactively.

Although the only part of the act that does mention "public domain" does not speak to whether authors have the right to dedicate their work to the public domain, the remainder of the committee report does not say that they intended copyright should be an indestructible form of property. Rather the language speaks to getting rid of formalities in order to comply with Berne (non-compliance had become a severe impediment in trade negotiations) and making registration and marking optional, but encouraged. A fair reading is that the Berne Act did not intend to take away author's right to dedicate works to the public domain, which they had (by default) under the 1976 Act.

Section 203 of the Copyright Act
Although there is support in the statutes for allowing work to be dedicated to the public domain, there cannot be an unlimited right to dedicate work to the public domain because of a quirk of U.S. copyright law which grants the author of a work the right to cancel "the exclusive or nonexclusive grant of a transfer or license of copyright or of any right under a copyright" thirty-five years later, unless the work was originally a work for hire
Work for hire

A work made for hire is an exception to the general rule that the person who actually creates a work is the legally-recognized author of that work....
.

It is unsettled how this section would mesh with a purported public domain dedication. Any of these interpretations are possible:

  • No effect. Any holder of a copyright can release it to the public domain. This interpretation is probably wrong, because then an author would lose the right to his "termination right," which in practical terms means a royalty. To prevent paying the royalty, a comic book company could release the copyright to the public domain but hold onto the trademark, which would suffice to prevent knock-off comics from being made. Because the Captain America case (Marvel v. Simon) showed that this termination right cannot be alienated before death, this interpretation is almost certainly wrong.
  • Some effect. An author may release his own work into the public domain, and a company holding a work for hire may release his work into the public domain. But a company which has purchased a copyright from an author (as was the case with most of the "Golden Age" comic book writers) cannot. Although the distinction of allowing an author to release his own work is not explicit in the statute, it may not be literally inconsistent (it is not a "transfer" or a "license," and it arguably is not a grant of a right under copyright), and this reading is necessary to comply with the 1990 Act discussed above, as well as the case law discussed below.
  • Strong effect. Only a company holding a work for hire can release the work into the public domain. Because of the references to "shareware" (above) and "programmers" (below), and the fact that many software companies in the 1980s were quite small (and thus did not have employees), this reading seems inconsistent with the intent of Congress.


Case law
Another form of support comes from the seminal case Computer Associates Int'l v. Altai
Computer Associates Int. Inc. v. Altai Inc.

Computer Associates International, Inc. v. Altai, Inc., 982 F.2d 693 is a leading decision from the United States Court of Appeals for the Second Circuit on how to establish copyright infringement for software....
, 982 F.2d 693. This case set the standard for determining copyright infringement of computer software and is still followed today. Moreover, it was decided by the Second Circuit appellate court, which is famous for handing down some of the most well-reasoned American copyright decisions. In this case, it discusses the public domain.

(c) Elements Taken from the Public Domain
Closely related to the non-protectability of scenes a faire, is material found in the public domain. Such material is free for the taking and cannot be appropriated by a single author even though it is included in a copyrighted work. … We see no reason to make an exception to this rule for elements of a computer program that have entered the public domain by virtue of freely accessible program exchanges and the like. See 3 Nimmer Section 13.03 [F] ; see also Brown Bag Software, slip op. at 3732 (affirming the district court’s finding that "[p]laintiffs may not claim copyright protection of an … expression that is, if not standard, then commonplace in the computer software industry."). Thus, a court must also filter out this material from the allegedly infringed program before it makes the final inquiry in its substantial similarity analysis.


This decision holds that computer software may enter the public domain through "freely accessible program exchanges and the like," or by becoming "commonplace in the computer industry." Relying only on this decision, it is unclear whether an author can dedicate his work to the public domain simply by labeling it as such, or whether dedication to the public domain requires widespread dissemination.

This could make a distinction in a CyberPatrol-like case, where a software program is released, leading to litigation, and as part of a settlement the author assigns his copyright. If the author has the power to release his work into the public domain, there would be no way for the new owner to stop the circulation of the program. A court may look on an attempt to abuse the public domain in this way with disfavor, particularly if the program has not been widely disseminated. Either way, a fair reading is that an author may choose to release a computer program to the public domain if he can arrange for it to become popular and widely disseminated.

Treatise analysis
The treatise cited holds in its most recent edition:

13.03[F][4]
It is axiomatic that material in the public domain is not protected by copyright, even when incorporated into a copyrighted work. …
An enormous amount of public domain software exists in the computer industry, perhaps to a much greater extent than is true of other fields. Nationwide computer "bulletin boards" permit users to share and distribute programs. In addition, computer programming texts may contain examples of actual code that programmers are encouraged to copy.
Programmers often will build existing public domain software into their works. The courts thus must be careful to limit protection only to those elements of the program that represent the author's original work.


Although Computer Associates only mentioned the issue in passing, Nimmer observes that the public domain is particularly rich and valuable for computer programs. He seems to say that a computer program author who wishes to release his work into the public domain may either include it in a book as example code or post it on a "bulletin board" and encourage sharing and distribution. (Nimmer is the treatise most widely cited in copyright opinions, and is generally authoritative.)

s, on the other hand, public use or publishing the details of an invention before applying for a patent will generally place an invention in the public domain and (in theory) prevent its subsequent patenting by anyone—an effective disclaimer. For example, a chemistry journal publishing a formula prevents patenting the formula by anyone. This tactic was commonly used by Bell Labs

 was famously described in this journal.) This is sometimes called "defensive disclosure"—one way to make sure you are not later accused of infringing a patent on your own invention. There is an exception to this rule, however: in U.S. (not European) law, an inventor may file a patent claim up to one year after publishing a description (but not, of course, if someone else published or used it first).

In practice, patent examiners only consider other patents and the books they have in their library for prior art, largely because the patent office has an elaborate classification system for inventions. This means that an increasing number of issued patents may be invalid, based upon prior art that was not brought to the examiner's attention. Once a patent is issued, it is very expensive to invalidate. Publishing a description on a website as a preemptive disclosure does very little in a practical sense to release an invention to the public domain; it might still be considered "patentable", although erroneously. However, anyone aware of an omitted prior art citation in an issued patent may submit it to the US Patent Office and request a "reexamination" of the patent during the enforceable period of the patent (that is, its life plus statute of limitations). This may result in loss of some or all of the patent on the invention, or it may backfire and actually strengthen the claims.

An applicant may also choose to file a Statutory Invention Registration

, which has the same effect as a patent for prior art purposes. These SIRs are relatively expensive. These are used strategically by large companies to prevent competitors from obtaining a patent.

Section 102(c) says that an invention that has been "abandoned" cannot be patented. There is precious little case-law on this point. It is largely a dead letter.

If an inventor has an issued patent, there are several ways to release it to the public domain (other than simply letting it expire). First, he can fail to pay the maintenance fee the next time it is due, about every four years. Alternatively he can file a under 37 CFR 1.321 for a reasonable fee. The regulations explicitly say that the "patentee may disclaim or dedicate to the public the entire term, or any terminal part of the term, of the patent granted. Such disclaimer is binding upon the grantee and its successors or assigns." Usually this is used during the application process to prevent another patent from a "double patenting

).

Some businesses choose to protect products, processes, and information by guarding them as trade secrets, rather than patenting them. Hershey Foods, Inc., for example, does not patent some of its processes, such as the recipe for Reese's, but rather maintains them as trade secrets, to prevent competitors from easily duplicating or learning from their invention disclosures, or from using the information after the patent lapses.

Terms can be deemed "generic" in two ways. First, any potential mark can be deemed "generic" by a trademark registry, that refuses to register it. In this instance, the term has no secondary meaning that helps consumers identify the source of the product; the term serves no function as a "mark". Second, a mark, already in use, may be deemed generic by a court or registry after the mark is challenged as generic—this is known as "genericide". In this instance, the term previously had a secondary meaning, but lost its source-identifying function.

To avoid "genericide", a trademark owner must balance between trying to dominate the market, and dominating their market to such an extent that their product name defines the market. A manufacturer who invents an amazing breakthrough product which cannot be succinctly described in plain English (for example, a vacuum-insulated drinking flask) will likely find its product described by the trademark ("Thermos"). If the product continues to dominate the market, eventually the trademark will become generic ("thermos").

However, "genericide" is not an inevitable process. In the late 1980s, "Nintendo

 never enters public domain in the sense that copyrighted material does. It is closer in nature to a trademark, in that a failure to maintain it makes it available for others to use (with different standards to maintain it from those for a trademark). If another party registers a lapsed domain name, it is no longer available to the public, as would be the case with former intellectual property which has become public domain.

Public domain and the Internet

The term "public domain" is often poorly understood and has created significant legal controversy. Historically, most parties attempting to address public domain issues fell into two camps:

  1. Businesses and organizations who could devote staff to resolving legal conflicts through negotiation and the court system.
  2. Individuals and organizations using materials covered by the fair use
    Fair use

    Fair use is a doctrine in United States copyright law that allows limited use of copyrighted material without requiring permission from the rights holders, such as use for scholarship or review....
     doctrine, reducing the need for substantial governmental or corporate resources to track down individual offenders.


With the advent of the Internet, however, it became possible for anybody with access to this worldwide network to "post" copyrighted or otherwise-licensed materials freely and easily. This aggravated an already established but false belief that if something is available through a free source, it must be public domain. Once such material was available on the net, it could be perfectly copied among thousands or even millions of computers very quickly and essentially without cost.

Freely obtained does not mean free to republish

These factors have reinforced the false notion that "freely obtained" means "public domain." One could argue that the Internet is a publicly available domain, not licensed or controlled by any individual, company, or government; therefore, everything on the Internet is public domain. This specious argument ignores the fact that licensing rights are not dependent on the means of distribution or consumer acquisition. (If someone gives a person stolen merchandise, it is still stolen, even if the receiving party was not aware of it.) Chasing down copyright violations based on the idea that information is inherently free has become a primary focus of industries whose financial structure is based on their control of the distribution of such media.

(Almost) everything written down is copyrighted

Another complication is that publishing exclusively on the Internet has become extremely popular. In countries party to the Berne Convention
Berne Convention for the Protection of Literary and Artistic Works

The Berne Convention for the Protection of Literary and Artistic Works, usually known as the Berne Convention, is an international agreement governing copyright, which was first accepted in Berne, Switzerland in 1886....
, an author's original works are covered by copyright as soon as the work is put into a "fixed" form; no formal copyright notice or registration is necessary. But such laws were passed at a time when the focus was on materials that could not be as easily and cheaply reproduced as digital media, nor did they comprehend the ultimate impossibility of determining which set of electronic bits is original. All Internet postings (including blogs and emails) are copyrighted material unless explicitly stated otherwise.

The distribution of many types of Internet postings (particularly Usenet
Usenet

Usenet, a portmanteau of "user" and "network", is a worldwide distributed Internet discussion system. It evolved from the general purpose UUCP architecture of the same name....
 articles and messages sent to electronic mailing lists) inherently involves duplication. The act of posting such a work can therefore be taken to imply consent to a certain amount of copying, as dictated by the technical details of the manner of distribution. However, it does not imply total waiver of copyright.

Furthering the public domain with the Internet

Many people are using the Internet to contribute to the public domain, or make works in the public domain more accessible to more people. For example, Wikisource
