Demonstrative evidence is evidence in the form of a representation of an object. This is, as opposed to, real evidence, testimony, or other forms of evidence used at trial.
Examples of demonstrative evidence include photos, x-rays, videotapes, movies, sound recordings, diagrams, forensic animation, maps, drawings, graphs, animation, simulations, and models. It is useful for assisting a finder of fact (fact-finder) in establishing context among the facts presented in a case. To be admissible, a demonstrative exhibit must “fairly and accurately” represent the real object at the relevant time. See Federal Rules of Evidence 901, 902, and 1001-1004 for an example from United States law.
Other examples of demonstrative evidence include case specific medical exhibits, colorized diagnostic films, general anatomy and surgery exhibits. These forms of demonstrative evidence are commonly used as a personal injury lawyer resource. Demonstrative evidence with dramatic impact can maximize the value of a case by effectively depicting catastrophic/traumatic injuries, complex surgical procedures, surgical mistakes or summarize injuries suffered by an individual. These examples of demonstrative evidence are used for settlement conferences, arbitration, mediation, medical expert depositions and trial presentations.
Demonstrative evidence is an effective aid in infringement litigation.
Whether prosecuting an infringer or defending a patent, originally filled patent drawings which are a part of most patent applications, can play an imperative part in any upcoming litigation. If the original patent drawings are not complete, accurate and exact, then the resulting output for litigation graphics is unreliable and could even hurt a case.
There are many ways to convert patent drawings into effective litigation graphics. Here are a few ways:
A patent drawing can be made visually transparent and overplayed onto an opposing image to show likeness or differences.
Color can be applied to elements of the original patent drawings and the same colors on similar elements of an opposing images to highlight likeness.
A front view from the application can be placed alongside a front view of the opposing invention with additions outlined in color to emphasize differences
A process flow chart from a utility patent application can be used alongside a flow chart of the opposing party with an insert between the two to indicate differences or similarities in process.
Callout information on a patent drawing can clarify key elements of the invention and emphasize important features.
Drawings from a patent application can be used in PowerPoint to create a simple tutorial using animation with color arrows, overlays and voice over to explain an invention.
Original patent drawings can be used as a basis to create complex 3D animations. Operation, technical procedures, incompatibilities between inventions and moving parts of an invention can be clearly presented. Furthermore, animations can indicate time, motion or speed, compare alternative theories or simplify highly complex data.
There are endless ways to manipulate original patent drawings to make compelling litigation graphics, each circumstance unique based on the setting, the invention, the desired outcome and budget.
Using original patent drawings as a starting point can save cost of having to start from scratch.
In many patent lawsuits filed, a substantial amount is spent on demonstrative evidence. WIPO Magazine stated, “according to a recent study by PricewaterhouseCoopers over 5,000 patent lawsuits – an all-time record – were filed, each costing on average around US$2.8 million.” Those numbers are for 2012; it is unlikely that costs have come down.

Before photographs and other demonstrative evidence, lawyers relied on purely testimonial or substantive evidence. Melvin Belli and Earl Rogers helped change that by introducing more demonstrative evidence.[ citation needed ] Scientific evidence emerged in the 1960s.[ citation needed ]

In American jurisprudence, demonstrative evidence, like any other kind of evidence must be relevant. At this point the proponent of the demonstrative evidence can either try to get the evidence admitted into the official record of the case or can choose to use the evidence as merely a prop. If the proponent of the evidence wants to have the evidence included in the official record of the case, the proponent will first ask for the evidence to be marked by the court for identification purposes. After the evidence is marked for identification, the proponent of the demonstrative evidence must lay a foundation. It is at this time that the relevancy of the demonstrative evidence is usually challenged. Laying of a foundation explains how the demonstrative evidence relates to the facts of the case and establishes the evidence's authenticity. Once the foundation is laid, the proponent may ask to officially move the piece of evidence into the record where it is marked as a full exhibit. If the evidence is marked as a full exhibit the jury may refer to the evidence during deliberations and in most jurisdictions the jury may examine the evidence during deliberations. If the evidence is not marked as a full exhibit, the jury cannot do these things. As a matter of courtesy, the proponent of the demonstrative evidence generally shows the piece of evidence to the opposing party before marking it for identification purposes. In criminal cases certain kinds of demonstrative evidence are subject to mandatory disclosure under the case law governing discovery. See Brady v. Maryland. While the law distinguishes between illustrative and substantive demonstratives, and jurors note this difference, jurors award damages regardless of the evidentiary status of demonstratives [1]
Examples of demonstrative evidence from popular culture include their use in these motion pictures:
Jury instructions, also known as charges or directions, are a set of legal guidelines given by a judge to a jury in a court of law. They are an important procedural step in a trial by jury, and as such are a cornerstone of criminal process in many common law countries.
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 the patent in order to enforce their rights.
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.
The Paris Convention for the Protection of Industrial Property, signed in Paris, France, on 20 March 1883, was one of the first intellectual property treaties. It established a Union for the protection of industrial property. The convention is currently still in force. The substantive provisions of the Convention fall into three main categories: national treatment, priority right and common rules.
Patent infringement is the commission of a prohibited act with respect to a patented invention without permission from the patent holder. Permission may typically be granted in the form of a license. The definition of patent infringement may vary by jurisdiction, but it typically includes using or selling the patented invention. In many countries, a use is required to be commercial to constitute patent infringement.
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.
Industrial property is one of two subsets of intellectual property, it takes a range of forms, including patents for inventions, industrial designs, trademarks, service marks, layout-designs of integrated circuits, commercial names and designations, geographical indications and protection against unfair competition. In some cases, aspects of an intellectual creation, although present, are less clearly defined. The object of industrial property consists of signs conveying information, in particular to consumers, regarding products and services offered on the market. Protection is directed against unauthorized use of such signs that could mislead consumers, and against misleading practices in general.
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. An issued patent can claim only 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 possibility 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.
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.
The USA 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.
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.
A patent application or patent may contain drawings, also called patent drawings, illustrating the invention, some of its embodiments, 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.
Patent law in modern mainland China began with the promulgation of the Patent Law of the People's Republic of China, in 1984. This law was modeled after patent systems of other civil law countries, particularly Germany and Japan.
Evans v. Eaton, 16 U.S. 454 (1818), was a United States Supreme Court case in which the Court held that a patent disclosing an improved method of manufacture by means of several different improved machines should be construed to claim both the method and the improvements to the machines, but not to include the machines apart from the inventor's improvements.
The following outline is provided as an overview of and topical guide to patents:
Evans v. Hettich, 20 U.S. 453 (1822), was a United States Supreme Court case in which the Court held that a witness's testimony could not be objected to merely because the witness suffered from "fits of derangement", as long as the witness was sane when he testified.
Republic Act No. 8293, otherwise known as The Intellectual Property Code of the Philippines lays down the rules and regulations that grant, and enforce patents in the Philippines. Patents may be granted to technical solutions such as an inventions, machines, devices, processes, or an improvement of any of the foregoing. The technical solution must be novel, innovative, and industrially useful. In order for a technical solution to be granted a patent, the inventor must file an application to the Bureau of Patents, which will examine, and in some cases, grant its approval. The law is designed as to foster domestic creativity, to attract foreign investors, and to motivate inventors to release their products for public access.
