Liquid packaging board is a multi-ply paperboard with high stiffness, strong wet sizing and a high barrier coating , e.g. plastic . Only virgin paper fibers are used. The barrier coating must hold the liquid and prevent migration of air and flavors through the paperboard.
81-418: A carton is a box or container usually made of liquid packaging board , paperboard and sometimes of corrugated fiberboard . Many types of cartons are used in packaging . Sometimes a carton is also called a box . A carton is a type of packaging typically made from paperboard that is suitable for food, pharmaceuticals, hardware, and many other types of products. Folding cartons are usually combined into
162-469: A decree by which new and inventive devices had to be communicated to the Republic in order to obtain legal protection against potential infringers. The period of protection was 10 years. As Venetians emigrated, they sought similar patent protection in their new homes. This led to the diffusion of patent systems to other countries. The English patent system evolved from its early medieval origins into
243-464: A capacity of 200 mL. Development of the carton slowed during World War II, but the design would see a revival within European markets in the 1960s. Gable top cartons are often used for liquid products such as milk, juice, etc. These use polyethylene -coated paperboard or other liquid packaging board and sometimes a foil laminate. Most are opened by pushing open the gables at the top back and pulling
324-453: A company helping another company to create a patented product or selling the patented product which is created by another company. There is also inducement to infringement, which is when a party induces or assists another party in violating a patent. An example of this would be a company paying another party to create a patented product in order to reduce their competitor's market share. This is important when it comes to gray market goods, which
405-425: A creative sense simplified to 'mechanical' painting-by-numbers. As these were extremely valuable, often commanded by the very richest art-buyers, including princes who hung them in their palaces and even took them on their travels as prestigious displays of wealth, often with a visual message, especially the world-famous Flemish ateliers were deemed worthy to have cartons made by some of the greatest graphic artists of
486-422: A hexagonal or octagonal cross sections are sometimes used for specialty items. Cartons can be made from many materials: paperboard , duplex, white kraft, recycled and many more various plastics, or a composite . Some are "food grade" for direct contact with foods. Many cartons are made out of a single piece of paperboard. Depending on the need, this paperboard can be waxed or coated with polyethylene to form
567-492: A machine to fold and seal a gable top paper carton. In 1957 paper milk carton company Kieckhefer Container Co. merged with the Weyerhauser Timber Company of Tacoma, Washington . Although quite often shaped like a cuboid , it is not uncommon to find cartons lacking right angles and straight edges, as in squrounds used for ice cream . Tetrahedrons and other shapes are available. Cartons with
648-567: A metal rule normally used to crease bags shifted in position and cut the bag. Gair concluded that cutting and creasing paperboard in one operation would have advantages; the first automatically made carton, now referred to as "semi-flexible packaging", was created. In 1817, the first commercial cardboard box production began in England. In 1879, Robert Gair , in Brooklyn, New York, operated a factory that die-ruled, cut, and scored paperboard into
729-453: A moisture barrier. This may serve to contain a liquid product or keep a powder dry. In art history, the carton (pronounced the French way) was a drawing on heavy pasteboard or paperboard, used as life-size design for the manufacture in an atelier of a valuable tapestry , such as a gobelin . During the weaving it hung behind the tapestry in the making, a time-consuming process thus in
810-403: A non-obvious inventive step. A patent is requested by filing a written application at the relevant patent office. The person or company filing the application is referred to as "the applicant". The applicant may be the inventor or its assignee. The application contains a description of how to make and use the invention that must provide sufficient detail for a person skilled in the art (i.e.,
891-417: A patent covers or the "scope of protection". After filing, an application is often referred to as " patent pending ". While this term does not confer legal protection, and a patent cannot be enforced until granted, it serves to provide warning to potential infringers that if the patent is issued, they may be liable for damages. Once filed, a patent application is "prosecuted" . A patent examiner reviews
SECTION 10
#1732779494585972-471: A patent. In the United States, however, only the inventor(s) may apply for a patent, although it may be assigned to a corporate entity subsequently and inventors may be required to assign inventions to their employers under an employment contract. In most European countries, ownership of an invention may pass from the inventor to their employer by rule of law if the invention was made in the course of
1053-439: A plethora of beverages and snacks found within carton-packaging. This includes milk, juices, egg whites, coffee, protein shakes, water, and even snacks like Goldfish and Whoppers . Liquid packaging board A liquid packaging board might be up to five plies and is formed on a multi-ply paper machine with online coating. The most common is to use three plies with a basis weight of about 300 g/m . The base or middle ply
1134-511: A prohibited act that is protected against by the patent. There is also the Doctrine of Equivalents. This doctrine protects from someone creating a product that is basically, by all rights, the same product that is protected with just a few modifications. In some countries, like the United States, there is liability for another two forms of infringement. One is contributory infringement, which is participating in another's infringement. This could be
1215-400: A right to make or use or sell an invention. Rather, a patent provides, from a legal standpoint, the right to exclude others from making, using, selling, offering for sale, or importing the patented invention for the term of the patent , which is usually 20 years from the filing date subject to the payment of maintenance fees . From an economic and practical standpoint however, a patent
1296-554: A single impression of a folded carton. By 1896, the National Biscuit Company was the first to use cartons to package crackers . During the first decade of the 1900s, G. W. Maxwell developed the first paper milk carton. In 1908, Dr. Winslow, of Seattle, Washington, described paper milk containers that were commercially sold in San Francisco and Los Angeles as early as 1906. The inventor of this carton
1377-570: A specific property right. Under the World Trade Organization 's (WTO) TRIPS Agreement , patents should be available in WTO member states for any invention, in all fields of technology , provided they are new , involve an inventive step , and are capable of industrial application . Nevertheless, there are variations on what is patentable subject matter from country to country, also among WTO member states. TRIPS also provides that
1458-513: A third party, without authorization from the patentee, makes, uses, or sells a patented invention. Patents, however, are enforced on a national basis. The making of an item in China, for example, that would infringe a US patent, would not constitute infringement under US patent law unless the item were imported into the US. Infringement includes literal infringement of a patent, meaning they are performing
1539-445: A tube at the manufacturer and shipped flat (knocked down) to the packager. Tray styles have a solid bottom and are often shipped as flat blanks and assembled by the packager. Some also are self-erecting. High-speed equipment is available to set up, load, and close the cartons. Egg cartons or trays are designed to protect whole eggs while in transit. Traditionally, these have been made of molded pulp . This uses recycled newsprint which
1620-555: A unified procedure for filing patent applications to protect inventions in each of its contracting states along with giving owners a 30-month priority for applications as opposed to the standard 12 the Paris Convention granted. A patent application filed under the PCT is called an international application, or PCT application. The steps for PCT applications are as follows: 1. Filing the PCT patent application 2. Examination during
1701-477: A yearly basis. Some countries or regional patent offices (e.g. the European Patent Office ) also require annual renewal fees to be paid for a patent application before it is granted. In the US, patent maintenance fees are due on 3.5, 7.5 and 11.5 anniversaries of the patent issuance. Only ca. 50% of issued US patents are maintained full term. Large corporations tend to pay maintenance fees through
SECTION 20
#17327794945851782-597: Is better and perhaps more precisely regarded as conferring upon its proprietor "a right to try to exclude by asserting the patent in court", for many granted patents turn out to be invalid once their proprietors attempt to assert them in court. A patent is a limited property right the government gives inventors in exchange for their agreement to share details of their inventions with the public. Like any other property right, it may be sold, licensed, mortgaged , assigned or transferred, given away, or simply abandoned. A patent, being an exclusionary right, does not necessarily give
1863-449: Is even more pronounced when the number of patent applications is normalized by the country's population each year, or when the country of origin rather than country of filing is used. For the US, the population-normalized peak in patenting occurred in 1915, and the number of subsequent patents induced per patent has been mostly declining since 1926. A study of 4,512 patents obtained by Stanford University between 1970 and 2020 showed that
1944-726: Is evidence that some form of patent rights was recognized in Ancient Greece in the city of Sybaris , the first statutory patent system is generally regarded to be the Venetian Patent Statute of 1474. However, recent historical research has suggested that the 1474 Statute was inspired by laws in the Kingdom of Jerusalem that granted monopolies to developers of novel silk-making techniques. Patents were systematically granted in Venice as of 1474, where they issued
2025-410: Is molded into a shape which protects the eggs. More recently, egg cartons have also been made from expanded polystyrene and PET . Cartons for liquids can be fabricated from laminates of liquid packaging board , foil, and polyethylene. Most are based on either Tetra Pak or SIG Combibloc systems. One option is to have the printed laminate supplied on a roll. The carton is cut, scored, and formed at
2106-457: Is normally made of pulp from bleached or unbleached chemical pulp, chemi-thermo-mechanical pulp (CTMP) or broke (waste paper from a paper machine). CTMP gives more bulk and stiffness. The top ply (inside) is made of bleached chemical pulp. The barrier coating depends on the application and might be applied on both sides. When induction welding is employed an aluminum foil layer is used for barrier protection and for heating. The back side of
2187-414: Is often referred to as a form of intellectual property right, an expression which is also used to refer to trademarks and copyrights , and which has proponents and detractors (see also Intellectual property § The term "intellectual property" ). Some other types of intellectual property rights are also called patents in some jurisdictions: industrial design rights are called design patents in
2268-623: Is patentable. Patentable material must be synthetic, meaning that anything natural cannot be patented. For example, minerals, materials, genes, facts, organisms, and biological processes cannot be patented, but if someone were to apply an inventive, non-obvious, step to them to synthesize something new, the result could be patentable. That includes genetically engineered strains of bacteria, as was decided in Diamond v. Chakrabarty. Patentability also depends on public policy and ethical standards. Additionally, patentable materials must be novel, useful, and
2349-470: Is possible by separating the layers before processing, though some recyclers only recycle the cardboard fibers. Perga cartons entered production in 1932 as a leak-proof can during World War I. Jagenberg Werke AG, in Düsseldorf, Germany, patented the design. The carton had a ribbed texture and paper sleeves covered in paraffin material, which provided a seamed structure from base to lid. Most cartons had

In some jurisdictions, there are opportunities for third parties to bring an opposition proceeding between grant and issuance, or post-issuance. Once granted the patent is subject in most countries to renewal fees to keep the patent in force. These fees are generally payable on
2511-547: Is the Paris Convention for the Protection of Industrial Property , initially signed in 1883. The Paris Convention sets out a range of basic rules relating to patents, and although the convention does not have direct legal effect in all national jurisdictions, the principles of the convention are incorporated into all notable current patent systems. The Paris Convention set a minimum patent protection of 20 years, but

2592-463: Is therefore only useful for protecting an invention in the country in which that patent is granted. In other words, patent law is territorial in nature. When a patent application is published, the invention disclosed in the application becomes prior art and enters the public domain (if not protected by other patents) in countries where a patent applicant does not seek protection, the application thus generally becoming prior art against anyone (including
2673-438: Is used for two package types: brick and gable top cartons . Patent A patent is a type of intellectual property that gives its owner the legal right to exclude others from making, using, or selling an invention for a limited period of time in exchange for publishing an enabling disclosure of the invention. In most countries, patent rights fall under private law and the patent holder must sue someone infringing
2754-434: Is when a patent owner sells a product in country A, wherein they have the product patented, then another party buys and sells it, without the owner's permission, in country B, wherein the owner also has a patent for the product. With either national or regional exhaustion being the law the in country B, the owner may still be able to enforce their patent rights; however, if country B has a policy of international exhaustion, then

Representatives of Indigenous peoples view the GRATK Treaty as a "first step towards guaranteeing just and transparent access to these resources." Before filing for an application, which must be paid for whether a patent is granted or not, a person will want to ensure that their material
2916-475: The U.S. Congress was passed on April 10, 1790, titled "An Act to promote the progress of useful Arts". The first patent under the Act was granted on July 31, 1790, to Samuel Hopkins of Vermont for a method of producing potash (potassium carbonate). A revised patent law was passed in 1793, and in 1836 a major revision was passed. The 1836 law instituted a significantly more rigorous application process, including
2997-465: The WIPO Treaty on Intellectual Property, Genetic Resources and Associated Traditional Knowledge (GRATK Treaty) mandating patent disclosure requirements for patents based on genetic resources and associated traditional knowledge from being granted. The Treaty contemplates revocation for patents incorrectly filed. The treaty, and in particular its planned extension, is seen as complementing
3078-637: The World Trade Organization (WTO) being particularly active in this area. The TRIPS Agreement has been largely successful in providing a forum for nations to agree on an aligned set of patent laws. Conformity with the TRIPS agreement is a requirement of admission to the WTO and so compliance is seen by many nations as important. This has also led to many developing nations, which may historically have developed different laws to aid their development, enforcing patents laws in line with global practice. Internationally, there are international treaty procedures, such as
3159-481: The plastic coating on the top side is 12 - 20 g/m and on the reverse side 15 - 60 g/m . Sanitary and aseptic processing of food contact products are critical. Liquid Packaging Board (LPB) is traditionally associated with beverage packaging, including for milk , juiceboxes and other dairy products, but its applications extend beyond just liquids, encompassing a broad range of uses due to its strength, barrier properties, and versatility. Liquid packaging board
3240-456: The term of protection available should be a minimum of twenty years. Some countries have other patent-like forms of intellectual property , such as utility models , which have a shorter monopoly period. The word patent originates from the Latin patere , which means "to lay open" (i.e., to make available for public inspection). It is a shortened version of the term letters patent , which

During the reign of Queen Anne , patent applications were required to supply a complete specification of the principles of operation of the invention for public access. Legal battles around the 1796 patent taken out by James Watt for his steam engine , established the principles that patents could be issued for improvements of an already existing machine and that ideas or principles without specific practical application could also legally be patented. The English legal system became

3402-835: The UK, substantive patent law is contained in the Patents Act 1977 as amended. In the United States, the Constitution empowers Congress to make laws to "promote the Progress of Science and useful Arts ...". The laws Congress passed are codified in Title 35 of the United States Code and created the United States Patent and Trademark Office . There is a trend towards global harmonization of patent laws, with
3483-545: The US, plant breeders' rights are sometimes called plant patents , and utility models and Gebrauchsmuster are sometimes called petty patents or innovation patents . The additional qualification utility patent is sometimes used (primarily in the US) to distinguish the primary meaning from these other types of patents. Particular types of patents for inventions include biological patents , business method patents , chemical patents and software patents . Although there

Commonly, a nation or a group of nations forms a patent office with responsibility for operating that nation's patent system, within the relevant patent laws. The patent office generally has responsibility for the grant of patents, with infringement being the remit of national courts. The authority for patent statutes in different countries varies. In
3645-530: The benefits of using each other's patented inventions. Freedom Licenses like the Apache 2.0 License are a hybrid of copyright/trademark/patent license/contract due to the bundling nature of the three intellectual properties in one central license. This can make it difficult to enforce because patent licenses cannot be granted this way under copyright and would have to be considered a contract. In most countries, both natural persons and corporate entities may apply for

Cartons filled with short-shelf-life dairy products use board that are barrier coated on both sides with one layer of low density polyethylene . For long-shelf-life products it is common to use aluminium foil as barrier coating together with polyethylene. Commonly
3807-400: The course of the 20th and 21st centuries, however, disparity is still prevalent. In the UK, for example, only 8% of inventors were female as of 2015. This can partly be attributed to historical barriers for women to obtain patents, as well as to the fact that women are underrepresented in traditionally "patent-intensive" sectors, particularly STEM sectors. Marcowitz-Bitton et al. argue that
3888-654: The establishment of an examination system. Between 1790 and 1836 about ten thousand patents were granted. By the American Civil War about 80,000 patents had been granted. In the US, married women were historically precluded from obtaining patents. While section 1 of the Patent Act of 1790 did refer to "she", married women were unable to own property in their own name and were also prohibited from rights to their own income, including income from anything they invented. This historical gender gap has lessened over
3969-647: The first modern patent system that recognised intellectual property in order to stimulate invention; this was the crucial legal foundation upon which the Industrial Revolution could emerge and flourish. By the 16th century, the English Crown would habitually abuse the granting of letters patent for monopolies . After public outcry, King James I of England (VI of Scotland ) was forced to revoke all existing monopolies and declare that they were only to be used for "projects of new invention". This
4050-630: The foundation for patent law in countries with a common law heritage, including the United States, New Zealand and Australia . In the Thirteen Colonies , inventors could obtain patents through petition to a given colony's legislature. In 1641, Samuel Winslow was granted the first patent in North America by the Massachusetts General Court for a new process for making salt. The modern French patent system

The costs of preparing and filing a patent application, prosecuting it until grant and maintaining the patent vary from one jurisdiction to another, and may also be dependent upon the type and complexity of the invention, and on
SECTION 50
#17327794945854212-510: The gender gap in patents is also a result of internal bias within the patent system. The number of patent applications filed each year has been growing for most countries although not smoothly, and jumps in activity are often observed due to changes in local laws. The high number of patent families for Spain in the 1800s is related to the superior preservation and cataloguing of the data by Spanish Patent and Trademark Office compared to other countries (see 1836 U.S. Patent Office fire ). The US
4293-502: The international phase 3. Examination during the national phase. Alongside these international agreements for patents there was the Patent Law Treaty (PLT). This treaty standardized the filing date requirements, standardized the application and forms, allows for electronic communication and filing, and avoids unintentional loss of rights, and simplifies patent office procedures. Sometimes, nations grant others, other than
4374-415: The invention be exploited in the jurisdiction it covers. Consequences of not working an invention vary from one country to another, ranging from revocation of the patent rights to the awarding of a compulsory license awarded by the courts to a party wishing to exploit a patented invention. The patentee has the opportunity to challenge the revocation or license, but is usually required to provide evidence that
4455-571: The inventor's normal or specifically assigned employment duties, where an invention might reasonably be expected to result from carrying out those duties, or if the inventor had a special obligation to further the interests of the employer's company. Applications by artificial intelligence systems, such as DABUS , have been rejected in the US, the UK, and at the European Patent Office on the grounds they are not natural persons. The inventors, their successors or their assignees become
4536-437: The licensee the right to make, use, sell, or import the claimed invention, usually in return for a royalty or other compensation. It is common for companies engaged in complex technical fields to enter into multiple license agreements associated with the production of a single product. Moreover, it is equally common for competitors in such fields to license patents to each other under cross-licensing agreements in order to share
4617-671: The most significant aspect of the convention is the provision of the right to claim priority : filing an application in any one member state of the Paris Convention preserves the right for one year to file in any other member state, and receive the benefit of the original filing date. Another key treaty is the Patent Cooperation Treaty (PCT), administered by the World Intellectual Property Organization (WIPO) and covering more than 150 countries. The Patent Cooperation Treaty provides
4698-442: The packager. A second option is to have the pre-assembled tubes delivered to the packaging plant for completion and filling. These are suited for aseptic processing and are used for milk, soup, juice, etc. Paperboard-based cartons are lighter compared to a similarly sized steel can, but are harder to recycle. Some open-loop recycling operations pelletize or flatten ground-up cartons for use in building materials; closed-loop recycling
4779-438: The patent in order to enforce their rights. The procedure for granting patents, requirements placed on the patentee, and the extent of the exclusive rights vary widely between countries according to national laws and international agreements. Typically, however, a patent application must include one or more claims that define the scope of protection that is being sought. A patent may include many claims, each of which defines
4860-399: The patent application to determine if it meets the patentability requirements of that country. If the application does not comply, objections are communicated to the applicant or their patent agent or attorney through an Office action , to which the applicant may respond. The number of Office actions and responses that may occur vary from country to country, but eventually a final rejection
4941-400: The patent owner seeks monetary compensation ( damages ) for past infringement, and seeks an injunction that prohibits the defendant from engaging in future acts of infringement, or seeks either damages or injunction. To prove infringement, the patent owner must establish that the accused infringer practises all the requirements of at least one of the claims of the patent. (In many jurisdictions

#17327794945855022-488: The patent owner the right to exploit the invention subject to the patent. For example, many inventions are improvements of prior inventions that may still be covered by someone else's patent. If an inventor obtains a patent on improvements to an existing invention which is still under patent, they can only legally use the improved invention if the patent holder of the original invention gives permission, which they may refuse. Some countries have "working provisions" that require
5103-427: The patent owner will have no legal grounds for enforcing the patent in country B as it was already sold in a different country. Patents can generally only be enforced through civil lawsuits (for example, for a US patent, by an action for patent infringement in a United States federal district court), although some countries (such as France and Austria ) have criminal penalties for wanton infringement. Typically,
5184-544: The patent owner, permissions to create a patented product based on different situations that align with public policy or public interest. These may include compulsory licenses, scientific research, and in transit in country. After two decades of drafting, the WIPO 's Intergovernmental Committee on Intellectual Property and Genetic Resources, Traditional Knowledge and Folklore moved to a Diplomatic Conference in May 2024 and adopted
5265-562: The patent should never have been granted. There are several grounds for challenges: the claimed subject matter is not patentable subject matter at all; the claimed subject matter was actually not new, or was obvious to the person skilled in the art , at the time the application was filed; or that some kind of fraud was committed during prosecution with regard to listing of inventors, representations about when discoveries were made, etc. Patents can be found to be invalid in whole or in part for any of these reasons. Patent infringement occurs when
5346-679: The permission of the other proprietor(s). The ability to assign ownership rights increases the liquidity of a patent as property. Inventors can obtain patents and then sell them to third parties. The third parties then own the patents and have the same rights to prevent others from exploiting the claimed inventions, as if they had originally made the inventions themselves. The grant and enforcement of patents are governed by national laws, and also by international treaties, where those treaties have been given effect in national laws. Patents are granted by national or regional patent offices, i.e. national or regional administrative authorities. A given patent
5427-690: The procedures under the European Patent Convention (EPC) [constituting the European Patent Organisation (EPOrg)], that centralize some portion of the filing and examination procedure. Similar arrangements exist among the member states of ARIPO and OAPI , the analogous treaties among African countries, and the nine CIS member states that have formed the Eurasian Patent Organization . A key international convention relating to patents
5508-443: The proprietors of the patent when and if it is granted. If a patent is granted to more than one proprietor, the laws of the country in question and any agreement between the proprietors may affect the extent to which each proprietor can exploit the patent. For example, in some countries, each proprietor may freely license or assign their rights in the patent to another person while the law in other countries prohibits such actions without
5589-400: The reasonable requirements of the public have been met by the working of invention. In most jurisdictions, there are ways for third parties to challenge the validity of an allowed or issued patent at the national patent office; these are called opposition proceedings . It is also possible to challenge the validity of a patent in court. In either case, the challenging party tries to prove that

In some countries there are requirements for providing specific information such as the usefulness of the invention, the best mode of performing the invention known to the inventor, or the technical problem or problems solved by the invention. Drawings illustrating the invention may also be provided. The application also includes one or more claims that define what

Although an infringer is generally free to rely on any available ground of invalidity (such as a prior publication , for example), some countries have sanctions to prevent the same validity questions being relitigated. An example is the UK Certificate of contested validity . Patent licensing agreements are contracts in which the patent owner (the licensor) agrees to grant

An accused infringer has the right to challenge the validity of the patent allegedly being infringed in a counterclaim . A patent can be found invalid on grounds described in the relevant patent laws, which vary between countries. Often, the grounds are a subset of requirements for patentability in

Incidentally, only 20% of Stanford patents in that dataset produced a positive net income for the university, while the rest was a net loss. Similar declines have been noted not only for the number of patents, but also for other measures of innovation output. Several hypotheses have been proposed as explanations for the observed decline: A patent does not give

Later, in 1915 John Van Wormer of Toledo, Ohio, received the a patent for the gable-topped, wax-coated, "paper bottle," a folded blank box for holding milk, calling it the "Pure-Pak." The milk carton could be folded, glued, filled with milk, and sealed at a dairy farm. In 1953, Seok-kyun Shin introduced the gable-topped milk carton to Korea. In the 1960s, Mario Lepore, a Detroit engineer designed

It is composed of the pulp of paper mixed with whiting (ground calcium carbonate ) and glue, this being forced into plaster moulds backed with paper, and then removed to a drying room to harden. It is much stronger and lighter than common plaster-of-Paris ornaments, and is not so liable to chip or break if struck with anything. There's

Similar grants included land patents , which were land grants by early state governments in the US, and printing patents , a precursor of modern copyright . In modern usage, the term patent usually refers to the right granted to anyone who invents something new, useful and non-obvious. A patent
