96-473: The film's storyline concerns a wealthy entrepreneur who buys moribund businesses in order to first refurbish and then sell them at a considerable profit. During his latest acquisition, he's attracted to the daughter of the company's owner, which complicates both his professional and private life. Grant Austen, the head of Austen Plastics, yearns for retirement. So when Schofield Industries, his largest customer, threatens to take its business elsewhere, Austen hires

192-469: 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

288-453: 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

384-418: A consulting firm, which finds an interested potential buyer, the notorious businessman Cash McCall. Cash meets with Austen and his daughter Lory, who owns part of the company. Austen conceals the problem he has with Schofield Industries. Afterwards, Cash speaks to Lory privately. It turns out they met the previous summer and were attracted to each other. However, when Lory showed up at his cabin soaking wet from

480-453: A jury. In other words, the purpose of written description is to support the terminology and the scope of patent claims . A patentee is not allowed to claim something that is not supported by the text of patent disclosure — this is the purpose of the written description . On the other hand, the purpose of enablement is to teach a person of ordinary skill in the art how to make and use the invention without undue experimentation . Enablement

576-403: 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.,

672-417: 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

768-471: 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

864-448: A pleasant piece of entertainment certain to delight audiences who crave life's complexities dished out in simple mouthfuls." Richard L. Coe of The Washington Post declared: "Exactly what the makers of 'Cash McCall' thought they were doing I don't know, but they have come up with a boozy fairy tale which to men will have all the appeal ' Cinderella ' presumably has for females." The Monthly Film Bulletin wrote, "The financial wangling

960-528: A precise description (such as molecular structure ) is not always possible in such cases, which makes it difficult to meet written description and enablement requirements for claims involving biological materials. One option to claim such biological inventions is by using plant patents . Another option is to use regular utility patents in combination with a deposit of the claimed biological material according to Budapest Treaty of 1977. The US law allows for such biological deposit(s) to be made at any time before

1056-511: 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

1152-400: 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

1248-663: A summer rainstorm later that night, Cash, not ready for a serious relationship, gently turned her away. Mortified by the rejection, she fled back into the storm. When he was unable to get Lory out of his mind, Cash realized he had made a big mistake. He overpays for Austen Plastics just so he can reconnect with her. Before the deal is finalized, Gil Clark, Cash's assistant, discovers that Austen Plastics holds patents essential to Schofield Industries. Its alarmed boss, retired Army General Danvers, tries to buy Austen Plastics himself. Cash then decides that he could run Schofield more profitably and starts secretly buying up controlling interest in

1344-513: 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

1440-555: 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

1536-480: A valid, enabling patent, they cannot take advantage of patent law's monopoly rights, and thus cannot stop competitors from developing the same product or process through proper means (such as independent invention or reverse engineering). Enabling disclosure is the price an inventor pays for patent monopoly. Article 83 of the European Patent Convention states that an application must disclose

1632-477: 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

1728-506: Is patentable subject matter from country to country, also among WTO member states. TRIPS also provides that 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

1824-407: Is a patent law requirement that a patent application disclose a claimed invention in sufficient detail so that the person skilled in the art could carry out that claimed invention. The requirement is fundamental to patent law: a monopoly is granted for a given period of time in exchange for a disclosure to the public how to make or practice the invention. The disclosure requirement lies at

1920-473: Is a key part of the patent "bargain"- an inventor gets a monopoly in return for teaching the world about their invention. Although in theory both "written description" and "enablement" should be applied to individual claims, when US courts find a lack of enablement, they usually invalidate the whole patent rather than individual claims. The historic evolution of the written description and enablement requirements can be found here. A patent disclosure "enables"

2016-419: Is a shortened version of the term letters patent , which was an open document or instrument issued by a monarch or government granting exclusive rights to a person, predating the modern patent system. 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

2112-481: Is also a ground for revocation under Section 72 of the UK Patents Act . For instance, an insufficiency of disclosure might arise if references to standardisation documents are provided to support essential aspects of the invention, but if these references are not sufficiently precise so that "the skilled person would have to make ... undue efforts to find and get together the information it needs to carry out

2208-476: Is an unpatenable product of Nature ) and the methods for identifying its inhibitors, the US5837479 did not provide any specific formulas for the claimed inhibitors. "Accordingly, the court concluded that the patent's claims are invalid for lack of written description," because "it claims a method of achieving a biological effect, but discloses no compounds that can accomplish that result." To summarize: without

2304-597: 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

2400-449: 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

2496-726: 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

2592-423: Is no publicly known method of making them. A patent claim that does not meet the enablement requirement may be rejected by the patent examiner before patent issuance or declared invalid upon re-examination or litigation after issuance. Enablement is determined as of the filing date of the patent, and patent owners cannot use experiments conducted post-application to establish the validity of their patents. Under

2688-424: Is often quite amusing ... but nothing can prevent the film's romantic stretches seeming a trite and tedious makeweight to Cash's amoral escapades in the financial jungle." 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

2784-623: 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

2880-511: Is required. A mere flow chart of a piece of software, for example, is adequate. Source code is not normally required. In the “unpredictable arts”, such as chemistry and pharmaceuticals , a very detailed description is required. In 1988 Federal Circuit established 8 Wands factors that can be considered when determining whether a disclosure requires undue experimentation: In a 2005 U.S. court case, several of Jerome H. Lemelson patents covering bar code readers were held to be invalid because

2976-436: Is sent by the patent office, or the patent application is granted, which after the payment of additional fees, leads to an issued, enforceable patent. 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

3072-547: 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

3168-463: 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

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

Cir. 2003), "[t]he purpose of the written description requirement is to prevent an applicant from later asserting that he invented that which he did not."

3552-475: 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

3648-465: 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

3744-762: 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

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 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

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

In May 2023, the U.S. Supreme Court did not specifically address the eight Wands factors in its decision in Amgen Inc v. Sanofi . However, the Court stated that the specification may call for a reasonable amount of experimentation to make and use the full scope of

4608-435: The claimed invention. In the United States, the would-be patentee must provide a "written description" of the invention, sufficient to support the claims of the patent during the patent's examination. "Written description" determines the scope of claims. The purpose of this rule is to avoid applicants speculatively filing for patents for inventions that they have not yet invented in order to get priority over competitors. As

This was one of three theatrical films produced with Garner as leading man during the period in which he was still playing the lead in the Warner Bros. television series Maverick (the other two were Darby's Rangers and Up Periscope ). Garner subsequently left

4800-400: 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

4896-408: The disclosure must also contain the inventor's "best mode" of making or practising the invention. For example, if an inventor knows that a liquid should be heated to 250 degrees for optimal performance, but discloses in the patent that the liquid should be heated to "above 200 degrees", then the inventor has not disclosed his "best mode" for carrying out the invention. The best mode must be disclosed for

4992-485: The early 1990s scientists at the University of Rochester discovered two disctinct cyclooxygenases , referred to as COX-1 and COX-2 . For most patents it is desirable to inhibit COX-2 and not COX-1. Previously known NSAIDs inhibit both COX-1 and COX-2, and thus they not only reduce inflammation, but also cause side effects such as stomach upset, irritation, ulcers, and bleeding. This breakthrough discovery prompted

5088-466: The entire invention, and not only its innovative aspects. The purpose of the “best mode” requirement is to ensure full disclosure, such that the inventor may not “disclose only what he knows to be his second-best embodiment, retaining the best for himself.” The "best mode requirement" only applies to what the inventor knows at the time the application is filed, not to what is subsequently discovered. Post- AIA , US law no longer permits invalidation of

5184-654: 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

Harrison's Reports wrote: "True, not too much attention to detail has been devoted to the real intricacies of business and high finance, but it's still

5376-647: 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

5472-630: 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

5664-510: 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

5760-629: The heart and origin of patent law. An inventor , or the inventor's assignee , is granted a monopoly for a given period of time in exchange for the inventor disclosing to the public how to make or practice their invention. If a patent fails to contain such information, then the bargain is violated, and the patent is unenforceable or can be revoked. Inventors who do not wish to teach the world about their invention still have some protection under trade secret law, which protects valuable secrets from being misappropriated through unfair means (such as theft or industrial espionage). But unless inventors apply for

Sometimes, nations grant others, other than

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

6048-457: The invention in a manner sufficiently clear and complete for it to be carried out by a person skilled in the art . Sufficiency is considered by the examiner during examination of a patent application and the requirement of Article 83 must be complied with in order for a patent to be granted. Insufficient disclosure is also a ground for opposition under Article 100(b) EPC and a ground for revocation under Article 138(1)(b) EPC . Insufficiency

6144-745: The invention". The patent law in the United States requires, among other things, that the patent specification "contain a written description of the invention, and of the manner and process of making and using it, in such full, clear, concise, and exact terms as to enable any person skilled in the art to which it pertains, or with which it is most nearly connected, to make and use the same." US Federal Courts and legal commentators have interpreted this statement as having two related but distinct requirements: written description and enablement . Although enablement and written description requirements share many similarities, their purposes are different. The enablement requirement relates to teaching how to make/use

6240-461: The invention, if it allows a person of ordinary skill in the art to practice the invention without undue experimentation. Patents may fail this test if they claim more than they teach: for example, a patent that claims all light bulbs but explains only how to make a particular type of light bulb. A patent may also be non-enabling, if it claims the use of tungsten filaments in a lightbulb, but it does not disclose how to make tungsten filaments, and there

6336-417: The invention. Biological (i.e. "capable of self-replication either directly or indirectly") materials (such as yeast, algae, protozoa, eukaryotic cells, cell lines, hybridomas, plasmids, viruses, plant tissue cells, lichens, seeds, vectors, cell organelles etc.) can be patented in the US as compositions of matter or as articles of manufacture , provided that they are useful, novel and non-obvious. However,

6432-461: The invention. In most countries, patent rights fall under private law and the patent holder must sue someone infringing 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

6528-416: The invention. In contrast, the written description requirement allows the patent owner to justify its claims, which determine the boundaries of the temporal monopoly on the invention. Also noteworthy is that US courts treat enablement as a ‘‘question of law based on underlying factual findings,’’ (i.e. with a judge having the final word), while written description requirement is a question of fact, decided by

6624-571: 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

6720-437: 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

6816-671: 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

6912-399: 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

7008-474: The patent issuance (and in some cases during reexamination ), however many other countries require deposits before patent filing. Such deposits are typically made for 30 years. In the United States , the sufficiency of disclosure requirement is complemented by an additional requirement, generally not found in other national patent jurisdictions: the "best mode requirement". According to the requirement,

7104-400: 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

7200-488: 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

7296-427: 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,

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

7488-562: 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

7584-679: 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

7680-611: 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

7776-443: 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

7872-400: 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

7968-437: The relevant area of technology) to make and use the invention. 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

8064-468: The relevant country. 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

8160-502: The right granted to anyone who invents something new, useful and non-obvious. A patent 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

8256-436: The scope of protection that is being sought. A patent may include many claims, each of which defines 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

8352-443: The scope of the patent may not be limited to what is literally stated in the claims, for example due to the doctrine of equivalents .) 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

8448-399: The second company. In the middle of all the deal making, Cash proposes marriage to Lory, and she accepts. However, Maude Kennard, the assistant manager of the hotel where Cash resides, wants Cash for herself and tricks Lory into believing that she is Cash's girlfriend. Meanwhile, one of Austen's business acquaintances, Harvey Bannon, convinces him that Cash swindled him and paid much less than

8544-431: The specification was not complete enough for a person of ordinary skill in the art of electrical engineering to have made and used the claimed invention at the time the patent was filed (1954) without undue experimentation. In this case the court held that a person of ordinary skill in the art was a degreed electrical engineer with two years of experience as of the filing date of the original patent application, 1954. One of

8640-517: The studio upon winning a contentious lawsuit and continued his movie career. Cash McCall screenplay writer and comedy novel best seller Marion Hargrove had also written several scripts for Garner's Maverick series. Garner wrote in his memoirs that he felt it was "not much of a movie, but I liked Natalie." The film received mixed reviews from critics. Howard Thompson of The New York Times called it "a painless, amusing movie exercise that now and then touches solid ground." Variety wrote that

8736-553: The type of patent. The European Patent Office estimated in 2005 that the average cost of obtaining a European patent (via a Euro-direct application, i.e. not based on a PCT application) and maintaining the patent for a 10-year term was around €32,000. Since the London Agreement entered into force on May 1, 2008, this estimation is however no longer up-to-date, since fewer translations are required. Sufficiency of disclosure Sufficiency of disclosure or enablement

8832-431: The university's patenting activity plateaued in the 2010s. 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

8928-410: The written description/sufficiency of disclosure requirement, an applicant might delay scientific and technical progress by blocking competitors from inventing something that the applicant has not yet invented (i.e. did not describe in his patent application). The written description requirement thus reinforces the idea that patents are a reward for inventing by requiring the applicant to show they possess

9024-472: Was created during the Revolution in 1791. Patents were granted without examination since inventor's right was considered as a natural one. Patent costs were very high (from 500 to 1,500 francs). Importation patents protected new devices coming from foreign countries. The patent law was revised in 1844 – patent cost was lowered and importation patents were abolished. The first Patent Act of

9120-612: Was incorporated into the Statute of Monopolies (1624) in which Parliament restricted the Crown's power explicitly so that the King could only issue letters patent to the inventors or introducers of original inventions for a fixed number of years. The Statute became the foundation for later developments in patent law in England and elsewhere. Important developments in patent law emerged during

9216-596: Was the World's leader in terms of patent families filed between 1900 and 1966, when Japan took over. Since 2007 PR China leads. However, in most technologically advanced countries (see, for example, France, Italy, Japan, Spain, Sweden, the UK in the figure on the right, as well as in Poland ), the total (i.e. regardless of the priority/inventors' country) number of patent families filed there have been declining in absolute numbers since c.  1970s –1980s. The decline
