Free World Trust V Électro Santé Inc
''Free World Trust v Électro Santé Inc'', 0002 S.C.R. 1024, 2000 SCC 66, is a leading Supreme Court of Canada decision on patents, namely claim construction and the necessity to identify essential elements and non-essential elements. Along with the related decision, '' Camco v. Whirlpool'' (2001), 9 C.P.R. (4th) 129 (SCC), the Supreme Court of Canada rejected the doctrine of equivalents applied in the United States and adopted the doctrine of purposive construction, as originally applied by the United Kingdom House of Lords in ''Catnic v. Hill & Smith''. This was a landmark decision as it resolved the uncertainty in Canadian case law between the two doctrines. The Court also articulated the scope of protection provided by patents and the requirements for patent infringement, infringement. Background Electro-magnetic therapeutic system is the English title of Canadian Patent 1,113,156 which was issued in 1981. The inventors Dr. Roland A. Drolet and Gaetan Charland, both from ...

Supreme Court Of Canada
The Supreme Court of Canada (SCC; french: Cour suprême du Canada, CSC) is the Supreme court, highest court in the Court system of Canada, judicial system of Canada. It comprises List of Justices of the Supreme Court of Canada, nine justices, whose decisions are the ultimate application of Canadian law, and grants permission to between 40 and 75 litigants each year to appeal decisions rendered by provincial, territorial and federal Appeal, appellate courts. The Supreme Court is bijural, hearing cases from two major legal traditions (common law and Civil law (legal system), civil law) and bilingual, hearing cases in both Official bilingualism in Canada, official languages of Canada (English language, English and French language, French). The effects of any judicial decision on the common law, on the interpretation of statutes, or on any other application of law, can, in effect, be nullified by legislation, unless the particular decision of the court in question involves applicatio ...

Purposive Theory
The purposive approach (sometimes referred to as purposivism, purposive construction, purposive interpretation, or the modern principle in construction) is an approach to statutory and constitutional interpretation under which common law courts interpret an enactment (a statute, part of a statute, or a clause of a constitution) within the context of the law's purpose. Purposive interpretation is a derivation of mischief rule set in ''Heydon's Case'', and intended to replace the mischief rule, the plain meaning rule and the golden rule. Purposive interpretation is used when the courts use extraneous materials from the pre-enactment phase of legislation, including early drafts, hansards, committee reports, and white papers. The purposive interpretation involves a rejection of the exclusionary rule. Israeli jurist Aharon Barak views purposive interpretation as a legal construction that combines subjective and objective elements.Barak, Aharon. ''Purposive Interpretation In Law''. Pr ...

Eddy Current
Eddy currents (also called Foucault's currents) are loops of electrical current induced within conductors by a changing magnetic field in the conductor according to Faraday's law of induction or by the relative motion of a conductor in a magnetic field. Eddy currents flow in closed loops within conductors, in planes perpendicular to the magnetic field. They can be induced within nearby stationary conductors by a time-varying magnetic field created by an AC electromagnet or transformer, for example, or by relative motion between a magnet and a nearby conductor. The magnitude of the current in a given loop is proportional to the strength of the magnetic field, the area of the loop, and the rate of change of flux, and inversely proportional to the resistivity of the material. When graphed, these circular currents within a piece of metal look vaguely like eddies or whirlpools in a liquid. By Lenz's law, an eddy current creates a magnetic field that opposes the change in the mag ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Electromagnetic Induction
Electromagnetic or magnetic induction is the production of an electromotive force (emf) across an electrical conductor in a changing magnetic field. Michael Faraday is generally credited with the discovery of induction in 1831, and James Clerk Maxwell mathematically described it as Faraday's law of induction. Lenz's law describes the direction of the induced field. Faraday's law was later generalized to become the Maxwell–Faraday equation, one of the four Maxwell equations in his theory of electromagnetism. Electromagnetic induction has found many applications, including electrical components such as inductors and transformers, and devices such as electric motors and generators. History Electromagnetic induction was discovered by Michael Faraday, published in 1831. It was discovered independently by Joseph Henry in 1832. In Faraday's first experimental demonstration (August 29, 1831), he wrapped two wires around opposite sides of an iron ring or "torus" (an arrangement ...

Electromagnetic Radiation
In physics, electromagnetic radiation (EMR) consists of waves of the electromagnetic field, electromagnetic (EM) field, which propagate through space and carry momentum and electromagnetic radiant energy. It includes radio waves, microwaves, infrared, Light, (visible) light, ultraviolet, X-rays, and gamma rays. All of these waves form part of the electromagnetic spectrum. Classical electromagnetism, Classically, electromagnetic radiation consists of electromagnetic waves, which are synchronized oscillations of electric field, electric and magnetic fields. Depending on the frequency of oscillation, different wavelengths of electromagnetic spectrum are produced. In a vacuum, electromagnetic waves travel at the speed of light, commonly denoted ''c''. In homogeneous, isotropic media, the oscillations of the two fields are perpendicular to each other and perpendicular to the direction of energy and wave propagation, forming a transverse wave. The position of an electromagnetic wave w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Magnetic Fields
A magnetic field is a vector field that describes the magnetic influence on moving electric charges, electric currents, and magnetic materials. A moving charge in a magnetic field experiences a force perpendicular to its own velocity and to the magnetic field. A permanent magnet's magnetic field pulls on ferromagnetic materials such as iron, and attracts or repels other magnets. In addition, a nonuniform magnetic field exerts minuscule forces on "nonmagnetic" materials by three other magnetic effects: paramagnetism, diamagnetism, and antiferromagnetism, although these forces are usually so small they can only be detected by laboratory equipment. Magnetic fields surround magnetized materials, and are created by electric currents such as those used in electromagnets, and by electric fields varying in time. Since both strength and direction of a magnetic field may vary with location, it is described mathematically by a function assigning a vector to each point of space, calle ...

Skilled Person
A person having ordinary skill in the art (abbreviated PHOSITA), a person of (ordinary) skill in the art (POSITA or PSITA), 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 (an "art"), without being a genius. The person mainly serves as a reference for determining, or at least evaluating, whether an invention is non-obvious or not (in U.S. patent law), or involves an inventive step or not (in European patent laws). 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. In some patent laws, the person skilled in the art is also used as a reference in the context of other criteria, for instance in order to determine whether an invention is sufficiently d ...

Research And Development
Research and development (R&D or R+D), known in Europe as research and technological development (RTD), is the set of innovative activities undertaken by corporations or governments in developing new services or products, and improving existing ones. Research and development constitutes the first stage of development of a potential new service or the production process. R&D activities differ from institution to institution, with two primary models of an R&D department either staffed by engineers and tasked with directly developing new products, or staffed with industrial scientists and tasked with applied research in scientific or technological fields, which may facilitate future product development. R&D differs from the vast majority of corporate activities in that it is not intended to yield immediate profit, and generally carries greater risk and an uncertain return on investment. However R&D is crucial for acquiring larger shares of the market through the marketisation ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Patent Act (Canada)
The ''Patent Act'' is Canadian federal legislation and is one of the main pieces of Canadian legislation governing patent law in Canada. It sets out the criteria for patentability, what can and cannot be patented in Canada, the process for obtaining a Canadian patent, and provides for the enforcement of Canadian patent rights. Purpose The purpose of a patent is to protect inventions. Patents provide the owner of a patent with the exclusive right to make, use and sell a patented invention. s 42. These restrictions form a system of encouraging economic and technical growth. The patent is a contract between the inventor and the government who represents society. The inventor obtains a monopoly limited to a 20-year term of producing and selling the patent. Society gains disclosure of the invention ...

Prior Art
Prior art (also known as state of the art or background 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 prior art is evaluated by patent offices as part of the patent granting process in what is called “substantive examination” of a patent application in order to determine whether an invention claimed in the patent application meets the novelty and inventive step or non-obviousness criteria for patentability. It may also be consid ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
