A patent application or patent may contain drawings, also called patent drawings, illustrating the invention, some of its embodiments (which are particular implementations or methods of carrying out the invention), or the prior art. The drawings may be required by the law to be in a particular form, and the requirements may vary depending on the jurisdiction.
Under the European Patent Convention, Article 78(1)EPC provides that a European patent application shall contain any drawings referred to in the description or the claims.[1] Drawings are therefore optional. Rule 46EPC specifies the form in which the drawings must be executed.[2]
The European search report is drawn up in respect of a European patent application on the basis of the claims, with due regard to the description and any drawings.[3] In addition, the extent of the protection conferred by a European patent or a European patent application is determined by the claims, with the description and drawings being used to interpret the claims.[4]
Patent Cooperation Treaty
Under the Patent Cooperation Treaty, Article 7PCT notably provides that the drawings are required when they are necessary for the understanding of the invention.[5]Rule 11.13PCT specifies special physical requirements for drawings in an international application.[6]

In the United States, the applicant for a patent is required by law to furnish a drawing of the invention whenever the nature of the case requires a drawing to understand the invention. This drawing must be filed with the application. This includes practically all inventions except compositions of matter or processes, but a drawing may also be useful in the case of many processes.[8]
The drawing must show every feature of the invention specified in the claims, and is required by the U.S. patent office rules to be in a particular form. The United States Patent and Trademark Office (USPTO) specifies the size of the sheet on which the drawing is made, the type of paper, the margins, and other details relating to the making of the drawing. The reason for specifying the standards in detail is that the drawings are printed and published in a uniform style when the patent issues, and the drawings must also be such that they can be readily understood by persons using the patent descriptions.[8]
No names or other identification are permitted within the "sight" of the drawing, and applicants are expected to use the space above and between the hole locations to identify each sheet of drawings. This identification may consist of the attorney's name and docket number or the inventor's name and application number and may include the sheet number and the total number of sheets filed (for example, "sheet 2 of 4"). The following rule, reproduced from title 37 of the Code of Federal Regulations, relates to the standards for drawings:[8][clarification needed]
From 1790 to 1880 in the US, patent models were required. A patent model was a scratch-built miniature model no larger than 12" by 12" by 12", approximately 30cm by 30cm by 30cm, that showed how an invention works. Some inventors still willingly submitted models at the turn of the twentieth century. In some cases, an inventor may still want to present a "working model" as an evidence to prove actual reduction to practice in an interference proceeding. In some jurisdictions patent models stayed an aid to demonstrate the operation of the invention. In applications involving genetics, samples of genetic material or DNA sequences may be required.
The United States patent law was revised in 1793. It stated that the Commissioner of the USPTO could ask for additional information, drawings, or diagrams if the description is not clear. By then, the rate of patent grants had grown to about 20 per year and the time burden on the Secretary of State was considered to be too burdensome. Patent applications were no longer examined. Patents were granted simply by submitting a written description of an invention, a model of the invention, if appropriate, and paying a fee of $30 then, and now $1000 in 2006 US dollars.
Drawings and photographs

In utility and design patent applications, drawings can be in black ink or color. Black and white drawings are normally required. On rare occasions, color drawings may be necessary as the only practical medium by which to disclose the subject matter sought to be patented in a utility or design patent application or the subject matter of a statutory invention registration.[8]
Black and white photographs are not ordinarily permitted in utility and design patent applications, unless this is the only practicable medium for illustrating the claimed invention. For example, photographs of electrophoresis gels, blots, autoradiographs, cell cultures, histological tissue cross sections, animals, plants, in vivo imaging, etc. Color photographs can be accepted in utility and design patent applications if the conditions for accepting color drawings and black and white photographs have been satisfied.[8]
Unlike utility patents, applications for design patents rely fully on the drawings. According to USPTO guidelines, "the drawing disclosure is the most important element of the application," and the drawings in design patent applications "constitute the entire visual disclosure of the claim." In well-executed drawings "nothing regarding the design sought to be patented is left to conjecture."[8]
Patent drawing features can contain the following features:[8]
Identification of drawings: includes the title of the invention, inventor's name, and application number.. etc.
Graphic forms in drawings. Chemical or mathematical formulae, tables, and waveforms may be submitted as drawings and are subject to the same requirements as drawings. Each chemical or mathematical formula must be labeled as a separate figure, using brackets when necessary, to show that information is properly integrated.
Type of paper: generally flexible, strong, white, smooth, matte (non-shiny), and durable.
Lead lines: between the reference characters and the details referred to.
Arrows: at the ends of lines, provided that their meaning is cleared.
Format requirements may differ by country where the patent is being filed.
The patent drawing can further contain a numbering of sheets of drawings, numbering of views, copyright notice, security markings, corrections (durable and permanent), no holes, and a type of drawing indication.
Views
The views in the drawing may be plan, elevation, section, or perspective views:[8]
Exploded views: views with the separated parts embraced by a bracket, to show the relationship or order of assembly of various parts are permissible.
Partial views: a view of a large machine or device in its entirety may be broken into partial views on a single sheet, or extended over several sheets if there is no loss in facility of understanding the view.
Sectional views: The plane upon which a sectional view is taken should be indicated on the view from which the section is cut by a broken line.
Alternate position: A moved position may be shown by a broken line superimposed upon a suitable view if this can be done without crowding; otherwise, a separate view must be used for this purpose, and
Modified forms. Modified forms of construction must be shown in separate views.

The European Patent Convention (EPC), also known as the Convention on the Grant of European Patents of 5 October 1973, is a multilateral treaty instituting the European Patent Organisation and providing an autonomous legal system according to which European patents are granted. The term European patent is used to refer to patents granted under the European Patent Convention. However, a European patent is not a unitary right, but a group of essentially independent nationally enforceable, nationally revocable patents, subject to central revocation or narrowing as a group pursuant to two types of unified, post-grant procedures: a time-limited opposition procedure, which can be initiated by any person except the patent proprietor, and limitation and revocation procedures, which can be initiated by the patent proprietor only.
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 the utmost importance both during prosecution and litigation alike.
A patent examiner is an employee, usually a civil servant with a scientific or engineering background, working at a patent office. Major employers of patent examiners are the European Patent Office (EPO), the United States Patent and Trademark Office (USPTO), the Japan Patent Office (JPO), and other patent offices around the world.
In United States patent law, utility is a patentability requirement. As provided by 35 U.S.C. § 101, an invention is "useful" if it provides some identifiable benefit and is capable of use and "useless" otherwise. The majority of inventions are usually not challenged as lacking utility, but the doctrine prevents the patenting of fantastic or hypothetical devices such as perpetual motion machines.
Patent prosecution describes the interaction between applicants and their representatives, and a patent office with regard to a patent, or an application for a patent. Broadly, patent prosecution can be split into pre-grant prosecution, which involves arguing before, and sometimes negotiation with, a patent office for the grant of a patent, and post-grant prosecution, which involves issues such as post-grant amendment and opposition.
In most patent laws, unity of invention is a formal administrative requirement that must be met for a patent application to proceed to grant. A patent application can basically relate only to one invention or a group of closely related inventions. The purpose of this requirement is administrative as well as financial. The requirement serves to preclude the option of filing one patent application for several inventions, while paying only one set of fees. Unity of invention also makes the classification of patent documents easier.
In the United States, under current patent law, the term of patent, provided that maintenance fees are paid on time, is 20 years from the filing date of the earliest U.S. or international (PCT) application to which priority is claimed.
Under United States patent law, a provisional application is a legal document filed in the United States Patent and Trademark Office (USPTO), that establishes an early filing date, but does not mature into an issued patent unless the applicant files a regular non-provisional patent application within one year. There is no such thing as a "provisional patent".
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.
A utility model is a patent-like intellectual property right to protect inventions. This type of right is available in many countries but, notably, not in the United States, United Kingdom or Canada. Although a utility model is similar to a patent, it is generally cheaper to obtain and maintain, has a shorter term, shorter grant lag, and less stringent patentability requirements. In some countries, it is only available for inventions in certain fields of technology and/or only for products. Utility models can be described as second-class patents.
In patent law, an inventor is the person, or persons in United States patent law, who contribute to the claims of a patentable invention. In some patent law frameworks, however, such as in the European Patent Convention (EPC) and its case law, no explicit, accurate definition of who exactly is an inventor is provided. The definition may slightly vary from one European country to another. Inventorship is generally not considered to be a patentability criterion under European patent law.
Japanese patent law is based on the first-to-file principle and is mainly given force by the Patent Act of Japan. Article 2 defines an invention as "the highly advanced creation of technical ideas utilizing the law of nature".
Maintenance fees or renewal fees are fees paid to maintain a granted patent in force. Some patent laws require the payment of maintenance fees for pending patent applications. Not all patent laws require the payment of maintenance fees and different laws provide different regulations concerning not only the amount payable but also the regularity of the payments. In countries where maintenance fees are to be paid annually, they are sometimes called patent annuities.
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.
This is a list of legal terms relating to patents. A patent is not a right to practice or use the invention, 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.
The grant procedure before the European Patent Office (EPO) is an ex parte, administrative procedure, which includes the filing of a European patent application, the examination of formalities, the establishment of a search report, the publication of the application, its substantive examination, and the grant of a patent, or the refusal of the application, in accordance with the legal provisions of the European Patent Convention (EPC). The grant procedure is carried out by the EPO under the supervision of the Administrative Council of the European Patent Organisation. The patents granted in accordance with the EPC are called European patents.
