Cripps Question
In patent law, the Cripps question is: :"Was it for all practical purpose obvious to any skilled chemist in the state of chemical knowledge existing at the date of the patent which consists of the chemical literature available (a selection of which appears in the Particulars of Objections) and his general chemical knowledge, that he could manufacture valuable therapeutic agents by making the higher alkyl resorcinols; ... ?" It was posed in the 1920s by Stafford Cripps in a British patent case about n-hexyl resorcinol, Sharp & Dohme Inc v Boots Pure Drug Company Ltd and approved by the Master of the Rolls Lord Hanworth in the Court of Appeal's judgment. If the answer was yes the patent was invalid for lack of inventive step or obviousness (or, in the terminology used at the time, want of subject matter). Referred to later as the Cripps question, this way of formulating the issue of inventive step in English law was deployed for many years thereafter. The Cripps question was note ...

Patent Law
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."A patent is not the grant of a right to make or use or sell. It does not, directly or indirectly, imply any such right. It grants only the right to exclude others. The supposition that a right to make is created by the patent grant is obviously inconsistent with the established distinctions between generic and specific patents, and with the well-known fact that a very considerable portion of the patents granted are in a field covered by a former relatively generic or basic patent, are tributary to such earlier patent, and cannot be practiced unless by license thereunder." – ''Herman v. Youngstown Car Mfg. Co.'', 191 F. 579, 584–85, 112 CCA 185 (6th Cir. 1911) In most countries, patent rights fall under private law and the patent holder mus ...

Stafford Cripps
Sir Richard Stafford Cripps (24 April 1889 – 21 April 1952) was a British Labour Party politician, barrister, and diplomat. A wealthy lawyer by background, he first entered Parliament at a by-election in 1931, and was one of a handful of Labour frontbenchers to retain his seat at the general election that autumn. He became a leading spokesman for the left-wing and co-operation in a Popular Front with Communists before 1939, in which year he was expelled from the Labour Party. During World War II, he served as Ambassador to the USSR (1940–42), during which time he grew wary of the Soviet Union, but achieved great public popularity because on being invaded by Nazi Germany the USSR stated its co-operation with the Allies and restoring peace, causing Cripps to be seen in 1942 as a potential rival to Winston Churchill for the premiership. He became a member of the War Cabinet of the wartime coalition, but failed in his efforts (the "Cripps Mission") to resolve the wartime cr ...

Resorcinol
Resorcinol (or resorcin) is an organic compound with the formula C6H4(OH)2. It is one of three isomeric benzenediols, the 1,3-isomer (or '' meta''-isomer). Resorcinol crystallizes from benzene as colorless needles that are readily soluble in water, alcohol, and ether, but insoluble in chloroform and carbon disulfide. Production Resorcinol is produced in several steps from benzene, starting with dialkylation with propylene to give 1,3-diisopropylbenzene. Oxidation and Hock rearrangement of this disubstituted arene gives acetone and resorcinol. Resorcinol is an expensive chemical, produced in only a very few locations around the world (to date only four commercial plants are known to be operative: in the United States, Germany,China and Japan), and as such it is the determining factor in the cost of PRF adhesives. Many additional routes exist for resorcinol. It was formerly produced by disulfonation of benzene followed by hydrolysis of the 1,3-disulfonate. This method ha ...

Master Of The Rolls
The Keeper or Master of the Rolls and Records of the Chancery of England, known as the Master of the Rolls, is the President of the Court of Appeal (England and Wales)#Civil Division, Civil Division of the Court of Appeal of England and Wales and Head of Civil Justice. As a judge, the Master of the Rolls is second in seniority in England and Wales only to the Lord Chief Justice of England and Wales, Lord Chief Justice. The position dates from at least 1286, although it is believed that the office probably existed earlier than that. The Master of the Rolls was initially a clerk responsible for keeping the "Rolls" or records of the Court of Chancery, and was known as the Keeper of the Rolls of Chancery. The Keeper was the most senior of the dozen Chancery clerks, and as such occasionally acted as keeper of the Great Seal of the Realm. The post evolved into a judicial one as the Court of Chancery did; the first reference to judicial duties dates from 1520. With the Supreme Court of ...

Inventive Step
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, " henonobviousness principle asks whether the invention is an adequate distance beyond or above the state of the art". The expression "inventive step" is predominantly used in Europe, while the expression "non-obviousness" is predominantly used in United States patent law. The expression "inventiveness" is sometimes used as well. Although the basic principle is roughly the same, the assessment of the inventive step and non-obviousness varies from one country to another. For instance, the practice of the European Patent Office (EPO) differs from the practice in the United Kingdom. Rationale The purpose of the inventive step, or non-obviousness, requirement is to avoid granting patents for inventions which only follow from "normal product design ...

English Law
English law is the common law legal system of England and Wales, comprising mainly criminal law and civil law, each branch having its own courts and procedures. Principal elements of English law Although the common law has, historically, been the foundation and prime source of English law, the most authoritative law is statutory legislation, which comprises Acts of Parliament, regulations and by-laws. In the absence of any statutory law, the common law with its principle of '' stare decisis'' forms the residual source of law, based on judicial decisions, custom, and usage. Common law is made by sitting judges who apply both statutory law and established principles which are derived from the reasoning from earlier decisions. Equity is the other historic source of judge-made law. Common law can be amended or repealed by Parliament. Not being a civil law system, it has no comprehensive codification. However, most of its criminal law has been codified from its common la ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Printed Circuit Board
A printed circuit board (PCB; also printed wiring board or PWB) is a medium used in Electrical engineering, electrical and electronic engineering to connect electronic components to one another in a controlled manner. It takes the form of a Lamination, laminated sandwich structure of conductive and insulating layers: each of the conductive layers is designed with an artwork pattern of traces, planes and other features (similar to wires on a flat surface) Chemical milling, etched from one or more sheet layers of copper Lamination, laminated onto and/or between sheet layers of a Insulator (electricity), non-conductive substrate. Electrical components may be fixed to conductive pads on the outer layers in the shape designed to accept the component's terminals, generally by means of soldering, to both electrically connect and mechanically fasten them to it. Another manufacturing process adds Via (electronics), vias: plated-through holes that allow interconnections between layers. ...
