Novelty is one of the patentability requirement for a patent claim, whose purpose is to prevent issuing patents on known things, i.e. to prevent public knowledge from being taken away from the public domain. [1]
An invention is anticipated (i.e. not new) and therefore not patentable if it was known to the public before the priority date of the patent application. Although the concept of "novelty" in patent law appears simple and self-explanatory, this view is very far from reality.[ attribution needed ] Some of the most contentious questions of novelty comprise:[ original research? ]
Novelty is requirement for a patent claim to be patentable. [1] In contrast, if an invention was known to the public before filing a patent application, or before its date of priority, if the priority of an earlier patent application is claimed, the invention is not considered new and therefore not patentable.[ citation needed ]
To assess the novelty of an invention, a search through what is called the prior art is usually performed, the term "art" referring to the relevant technical field. A prior art search is generally performed with a view to proving that the invention is "not new" or old. No search can possibly cover every single publication or use on earth, and therefore cannot prove that an invention is "new". A prior art search may for instance be performed using a keyword search of large patent databases, scientific papers and publications, and on any web search engine. However, it is impossible to guarantee the novelty of an invention, even once a patent has been granted, since some little known publication may have disclosed the claimed invention.[ citation needed ]
A patent grants an inventor a legally enforceable monopoly over their invention. This means that others can be legally restrained from exploiting the invention. It is not the intention of the patent system to deny anyone what they have been free to do before someone claims an invention. For example, one cannot patent the wheel, as that would exclude others from doing what they had previously been free to do. The legal test is that the invention must be something new, i.e. it must possess "novelty". The invention of the wheel is not new, because the wheel already forms part of the prior art.
In some countries, such as the Australia, Canada, China, Japan, Russia, United States, a grace period exists for protecting an inventor or their successor in title from authorised or unauthorised disclosure of the invention before the filing date. That is, if the inventor or the successor in title publishes the invention, an application can still be validly filed which will be considered novel despite the publication, provided that the filing is made during the grace period following the publication. The grace period is usually 6 or 12 months. In China, the grace period is 6 months.[ citation needed ] In Russia, the grace period is 6 months (Civil Code part IV, article 1350 (3)). In US, the grace period is 12 months ("Leahy-Smith America Invents Act")
In other countries, such as in EPO members, any act that makes an invention available to the public, no matter where in the world, before the filing date or priority date has the effect of barring the invention from being patented. Examples of acts that can make an invention available to the public are written publications, sales, public oral disclosures and public demonstrations or use.
The grace period should not be confused with the priority year defined by Paris Convention for the Protection of Industrial Property. The priority year starts when the first filing in a contracting state of the Paris Convention is made, while the grace period starts from the pre-filing publication.
Local novelty only regards publications, uses or sales that have taken place within that jurisdiction to be novelty destroying.

Another controversial issue in novelty analysis is whether a discovery and isolation of a product of nature should be patentable. In 1911, Billings Learned Hand, who had been only 2 years in his position as a judge, "had made an uninformed mistake in Parke-Davis v. Mulford" [5] by pronouncing that naturally occurring adrenaline can be patented in its pure form. [6] This judicial tradition, allowing patenting of isolated natural products in the US, continued for over 100 years. Another notable example of it was In re Bergstrom , where a court reversed the Patent Office’s refusal to patent on prostaglandins. In Amgen, Inc. v. Chugai Pharmaceutical Co. (1991) and Schering Corp. v. Amgen Inc (2000), courts confirmed patentability of recombinant DNA molecules, which encode known proteins.
The practice of patenting isolated products of nature came to an end only in 2013, when the SCOTUS decided in Association for Molecular Pathology v. Myriad Genetics, Inc. that an isolated product of Nature (a DNA sequence in that case) does not deserve a composition-of-matter claim. At the same time, the Court decided that complementary DNA, which is produced by reverse transcription of messenger RNA and does not contain introns, can be patentable. It is worth noting, that the denial of patentability in this case was not based on novelty, but rather on subject matter eligibility.
Anticipation refers to advance use or disclosure of an otherwise-patentable invention, thereby undermining its novelty. The United Kingdom's House of Lords referred to "anticipation" as "convenient" terminology to cover "that part of the state of art which is inconsistent with the invention being new". [7] Anticipation and infringement are two sides of the same coin: that which anticipates earlier in time would infringe later in time. [8]
Point of novelty is a term used in patent law to distinguish those elements or limitations in a patent claim that are conventional or known from those elements or limitations that are novel, i.e. not conventional or known.[ citation needed ] That part of the invention may also be termed its "point of departure from the prior art".[ citation needed ] The term is also applied to a patentability test – the point of novelty test – which determines patentability (usually, obviousness) by considering the point(s) of novelty after dissecting out the conventional part.[ citation needed ]
In a Jepson claim, the conventional parts of the claim elements are placed in a preamble, such as "In a grease gun comprising a cylinder enclosing a piston longitudinally movable in said cylinder, said cylinder having a nozzle at a distal end thereof", which is followed by a transitional phrase such as "the improvement comprising", which is followed by a recitation of the element or elements constituting the point of novelty, such as "said nozzle having a fluted opening at a distal end thereof".[ citation needed ]
A conceptual problem may arise in applying the point of novelty method of analysis when the elements at the point of novelty cooperate or co-act with the conventional elements or part of them in a novel way.[ citation needed ] The novel co-action is properly considered part of the point of novelty of the invention and should therefore properly be recited after the transitional phrase.[ citation needed ]
The United States Court of Appeals for the Federal Circuit formerly used the point of novelty test for design patents as the basis of a patent infringement analysis, but the court recently abandoned that test in Egyptian Goddess, Inc. v. Swisa, Inc. [9] The Federal Circuit has at times criticized use of the point of novelty test in obviousness analysis, [10] but the Supreme Court has continued to use a point of novelty test for obviousness. [11] In Parker v. Flook the Supreme Court analyzed patent-eligibility (statutory subject matter) under a point of novelty test, citing Neilson v. Harford and O'Reilly v. Morse as authority, but in Diamond v. Diehr , the Court used the opposite approach. Then in Mayo v. Prometheus and Alice v. CLS Bank the Supreme Court went back to the test of the Flook case.
Present-day American patent law still acknowledges that some parts of a patent claim may constitute "insignificant post-solution activity". This is regarded as a kind of "point of novelty" approach, disallowed under present (Federal Circuit) patent law. To combat infringement, truly "insignificant" elements are routinely kept out of patent claims. [12] The purpose of the patent-eligibility doctrine concerning insignificant post-solution activity, however, is that adding such limitations to a claim does not involve adding an "inventive concept" to the otherwise ineligible underlying idea. [13]
The "contribution approach" in European patent law is similar to the American "point of novelty" approach. It is supposed to be invalid, but it is still being applied under various guises in order to avoid counter-intuitive results.
In Canada, the requirements for novelty are codified under section 28.2 of the Patent Act (R.S.C., 1985, c. P-4): [14]
- 28.2 (1) The subject-matter defined by a claim in an application for a patent in Canada (the “pending application”) must not have been disclosed
- (a) more than one year before the filing date by the applicant, or by a person who obtained knowledge, directly or indirectly, from the applicant, in such a manner that the subject-matter became available to the public in Canada or elsewhere;
- (b) before the claim date by a person not mentioned in paragraph (a) in such a manner that the subject-matter became available to the public in Canada or elsewhere;
- (c) in an application for a patent that is filed in Canada by a person other than the applicant, and has a filing date that is before the claim date;
- ...
The section does not restrict disclosure to prior patents, giving a broad description of what includes prior disclosure; so long as the subject-matter was disclosed “in such manner that the subject-matter became available to the public”, the subject-matter is barred from being patented. [15] This may include prior patents, publications or the invention itself being put on display. Disclosures in a private document, such as an internal memo that is not available to the public, do not count. [16]
There is an eight-pronged test to determine whether anticipation occurs in Canada. The prior art must:
The current test now requires that only 1 of the 8 tests be fulfilled in order to find anticipation. [18]
Under the European Patent Convention (EPC), European patents shall be granted for inventions which, among other things, are new. The central legal provision governing the novelty under the EPC is Article 54 EPC.
In the United States the four most common ways in which an inventor will be barred under Section 102 are:[ citation needed ]
In U.S. patent law, a claim lacks novelty, and anticipation occurs when one prior art reference or event discloses all the features of a claim and enables one of ordinary skill in the art to make and use the invention. The term "features" in this context refers to the elements of art of the claim or its limitations as explained in the all elements rule.
A prior art reference must not only disclose every feature of a claim, but must also disclose the features arranged or combined in the same way as the claim. [19] [ jargon ]
Prior art is a concept in patent law used to determine the patentability of an invention, in particular whether an invention meets the novelty and the inventive step or non-obviousness criteria for patentability. In most systems of patent law, prior art is generally defined as anything that is made available, or disclosed, to the public that might be relevant to a patent's claim before the effective filing date of a patent application for an invention. However, notable differences exist in how prior art is specifically defined under different national, regional, and international patent systems.
In patent law, industrial design law, and trademark law, a priority right or right of priority is a time-limited right, triggered by the first filing of an application for a patent, an industrial design or a trademark respectively. The priority right allows the claimant to file a subsequent application in another country for the same invention, design, or trademark effective as of the date of filing the first application. When filing the subsequent application, the applicant must claim the priority of the first application in order to make use of the right of priority. The right of priority belongs to the applicant or his successor in title.
In a patent or patent application, the claims define in technical terms the extent, i.e. the scope, of the protection conferred by a patent, or the protection sought in a patent application. In other words, the purpose of the claims is to define which subject-matter is protected by the patent. This is termed as the "notice function" of a patent claim—to warn others of what they must not do if they are to avoid infringement liability. The claims are of paramount importance in both prosecution and litigation.
A person having ordinary skill in the art, a person of (ordinary) skill in the art, a person skilled in the art, a skilled addressee or simply a skilled person is a legal fiction found in many patent laws throughout the world. This hypothetical person is considered to have the normal skills and knowledge in a particular technical field, without being a genius. This measure mainly serves as a reference for determining, or at least evaluating, whether an invention is non-obvious or not, or involves an inventive step or not. If it would have been obvious for this fictional person to come up with the invention while starting from the prior art, then the particular invention is considered not patentable.
Within the context of a national or multilateral body of law, an invention is patentable if it meets the relevant legal conditions to be granted a patent. By extension, patentability also refers to the substantive conditions that must be met for a patent to be held valid.
The inventive step and non-obviousness reflect a general patentability requirement present in most patent laws, according to which an invention should be sufficiently inventive—i.e., non-obvious—in order to be patented. In other words, "[the] nonobviousness principle asks whether the invention is an adequate distance beyond or above the state of the art".
Sufficiency of disclosure or enablement 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 United States is considered to have the most favorable legal regime for inventors and patent owners in the world. Under United States law, a patent is a right granted to the inventor of a (1) process, machine, article of manufacture, or composition of matter, (2) that is new, useful, and non-obvious. A patent is the right to exclude others, for a limited time from profiting of a patented technology without the consent of the patent-holder. Specifically, it is the right to exclude others from: making, using, selling, offering for sale, importing, inducing others to infringe, applying for an FDA approval, and/or offering a product specially adapted for practice of the patent.
A patent application is a request pending at a patent office for the grant of a patent for an invention described in the patent specification and a set of one or more claims stated in a formal document, including necessary official forms and related correspondence. It is the combination of the document and its processing within the administrative and legal framework of the patent office.
G 1/03 and G 2/03 are two decisions of the Enlarged Board of Appeal of the European Patent Office (EPO), which were both issued on April 8, 2004.
This is a list of legal terms relating to patents and patent law. A patent is not a right to practice or use the invention claimed therein, but a territorial right to exclude others from commercially exploiting the invention, granted to an inventor or his successor in rights in exchange to a public disclosure of the invention.
Title 35 of the United States Code is a title of United States Code regarding patent law. The sections of Title 35 govern all aspects of patent law in the United States. There are currently 37 chapters, which include 376 sections, in Title 35.
Canadian patent law is the legal system regulating the granting of patents for inventions within Canada, and the enforcement of these rights in Canada.
Article 123 of the European Patent Convention (EPC) relates to the amendments under the EPC, i.e. the amendments to a European patent application or patent, and notably the conditions under which they are allowable. In particular, Article 123(2) EPC prohibits adding subject-matter going beyond the content of the application as filed, while Article 123(3) EPC prohibits an extension of the scope of protection by amendment after grant. In addition, Rule 80 EPC limits the types of amendments that can be done during opposition proceedings before the European Patent Office (EPO), and Rule 139 EPC relates to the correction of errors in documents filed with the EPO.
Article 83 of the European Patent Convention (EPC) relates to the disclosure of the invention under the European Patent Convention. This legal provision prescribes that a European patent application must disclose the invention in a manner sufficiently clear and complete for it to be carried out by a person skilled in the art.
The all elements rule or all limitations rule is a legal test used in US patent law to determine whether a given reference shows that a patent claim lacks the novelty required to be valid. The rule is also applicable to an obviousness analysis. Under the rule, a single reference or the combination of references relied upon, plus the ordinary knowledge of persons skilled in the art, must provide each claimed element. For anticipation, and under certain circumstances for obviousness, the doctrine of inherency may be relied on to meet this test.
Under the European Patent Convention (EPC), European patents shall be granted for inventions which inter alia are new. The central legal provision explaining what this means, i.e. the central legal provision relating to the novelty under the EPC, is Article 54 EPC. Namely, "an invention can be patented only if it is new. An invention is considered to be new if it does not form part of the state of the art. The purpose of Article 54(1) EPC is to prevent the state of the art being patented again."
For a patent to be valid in Canada, the invention claimed therein needs to be new and inventive. In patent law, these requirements are known as novelty and non-obviousness. A patent cannot in theory be granted for an invention without meeting these basic requirements or at least, if a patent which does not meet these requirements is granted, it cannot later be maintained. These requirements are borne out of a combination of statute and case law.
Apotex Inc v Sanofi-Synthelabo Canada Inc, [2008] 3 S.C.R. 265, is a leading Supreme Court of Canada decision on the novelty and non-obviousness requirements for a patent in Canada. The Court rejected a challenge by the generic drug manufacturer Apotex to declare Synthelabo Canada's patent for Plavix, an anti-coagulant drug, invalid. At issue was whether selection patents are invalid in principle, and if they are not, whether the subject selection patent was invalid on the grounds of anticipation, obviousness or double patenting.
In US patent law, non-obviousness is one of the requirements that an invention must meet to qualify for patentability, codified as a part of Patent Act of 1952 as 35 U.S.C. §103. An invention is not obvious if a "person having ordinary skill in the art" (PHOSITA) would not know how to solve the problem at which the invention is directed by using exactly the same mechanism. Since the PHOSITA standard turned to be too ambiguous in practice, the U.S. Supreme Court provided later two more useful approaches which currently control the practical analysis of non-obviousness by patent examiners and courts: Graham et al. v. John Deere Co. of Kansas City et al., 383 U.S. 1 (1966) gives guidelines of what is "non-obvious", and KSR v. Teleflex (2006) gives guidelines of what is "obvious".
