Leitch Manufacturing Co. V. Barber Co.
''Leitch Manufacturing Co. v. Barber Co.'', 302 U.S. 458 (1938), is a 1938 decision of the United States Supreme Court extending the tie-in patent misuse doctrine to cases in which the patentee does not use an explicit tie-in license but instead relies on grants of implied licenses to only those who buy a necessary supply from it. Background Facts Barber Asphalt Company acquired HaydeU.S. Patent No. 1,684,671 covering a "Method of preventing evaporation from concrete during curing." The patent describes a process for improving the curing of concrete by retarding the evaporation of water from poured concrete, as in a roadway. The process involves preparing a mixture of bitumen Asphalt, also known as bitumen (, ), is a sticky, black, highly viscous liquid or semi-solid form of petroleum. It may be found in natural deposits or may be a refined product, and is classed as a pitch. Before the 20th century, the term a ..., soap, and water, which forms bituminous emulsion, ...

United States Supreme Court
The Supreme Court of the United States (SCOTUS) is the highest court in the federal judiciary of the United States. It has ultimate appellate jurisdiction over all U.S. federal court cases, and over state court cases that involve a point of federal law. It also has original jurisdiction over a narrow range of cases, specifically "all Cases affecting Ambassadors, other public Ministers and Consuls, and those in which a State shall be Party." The court holds the power of judicial review, the ability to invalidate a statute for violating a provision of the Constitution. It is also able to strike down presidential directives for violating either the Constitution or statutory law. However, it may act only within the context of a case in an area of law over which it has jurisdiction. The court may decide cases having political overtones, but has ruled that it does not have power to decide non-justiciable political questions. Established by Article Three of the United States C ...

Patent Misuse
In United States patent law, patent misuse is a patent holder's use of a patent to restrain trade beyond enforcing the exclusive rights that a lawfully obtained patent provides. If a court finds that a patent holder committed patent misuse, the court may rule that the patent holder has lost the right to enforce the patent. Patent misuse that restrains economic competition substantially can also violate United States antitrust law.. Definition Patent misuse is a patent owner's improper use of patent rights, speaking very generally, to expand the scope or term of the patent. Examples of such patent misuse include forcing customers to agree to pay royalties on unpatented products or to pay royalties on an expired patent. This type of patent misuse can take place without a violation of antitrust laws. But it violates such policies of US patent law as the monopoly of a patent is confined to what its claims cover and once a patent expires the public has an unlimited right to practice ...

Barber Asphalt Company
Barber Asphalt Company of Washington, D.C. started in 1883 was founded by Amzi L. Barber. Barber, born in 1843. Barber first career was a teaching professor, he moved to real estate. In real estate, he found the problem of needing affordable paved roads. He found that asphalt was a great affordable material for paved roads. He added asphalt shingles to his products. In 1879 he moved Headquarters to New York City. He had offices in Washington, D.C. from 1878 to 1912, Philadelphia, Pennsylvania from 1912 to 1938 and Maurer, Perth Amboy, New Jersey from 1938 to 1948. In 1888 Barber leased the largest know asphalt deposit at Pitch Lake Trinidad. Barber opened a subsidiary, called the Iroquois division, and Iroquois Electric Refrigeration Company. Elkins Widener purchased the company in 1898 and merged with his Trinidad Corporation subsidiary. This formed the Asphalt Company of America of New York. In 1899 Asphalt Company of America was sold to John M. Mack and renamed, National Asphal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bitumen
Asphalt, also known as bitumen (, ), is a sticky, black, highly viscous liquid or semi-solid form of petroleum. It may be found in natural deposits or may be a refined product, and is classed as a pitch. Before the 20th century, the term asphaltum was also used. Full text at Internet Archive (archive.org) The word is derived from the Ancient Greek ἄσφαλτος ''ásphaltos''. The largest natural deposit of asphalt in the world, estimated to contain 10 million tons, is the Pitch Lake located in La Brea in southwest Trinidad (Antilles island located on the northeastern coast of Venezuela), within the Siparia Regional Corporation. The primary use (70%) of asphalt is in road construction, where it is used as the glue or binder mixed with aggregate particles to create asphalt concrete. Its other main uses are for bituminous waterproofing products, including production of roofing felt and for sealing flat roofs. In material sciences and engineering, the terms "asphalt" an ...

Concrete
Concrete is a composite material composed of fine and coarse aggregate bonded together with a fluid cement (cement paste) that hardens (cures) over time. Concrete is the second-most-used substance in the world after water, and is the most widely used building material. Its usage worldwide, ton for ton, is twice that of steel, wood, plastics, and aluminum combined. Globally, the ready-mix concrete industry, the largest segment of the concrete market, is projected to exceed $600 billion in revenue by 2025. This widespread use results in a number of environmental impacts. Most notably, the production process for cement produces large volumes of greenhouse gas emissions, leading to net 8% of global emissions. Other environmental concerns include widespread illegal sand mining, impacts on the surrounding environment such as increased surface runoff or urban heat island effect, and potential public health implications from toxic ingredients. Significant research and development is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Motion Picture Patents Co
In physics, motion is the phenomenon in which an object changes its position with respect to time. Motion is mathematically described in terms of displacement, distance, velocity, acceleration, speed and frame of reference to an observer and measuring the change in position of the body relative to that frame with change in time. The branch of physics describing the motion of objects without reference to its cause is called kinematics, while the branch studying forces and their effect on motion is called dynamics. If an object is not changing relative to a given frame of reference, the object is said to be ''at rest'', ''motionless'', ''immobile'', '' stationary'', or to have a constant or time-invariant position with reference to its surroundings. Modern physics holds that, as there is no absolute frame of reference, Newton's concept of '' absolute motion'' cannot be determined. As such, everything in the universe can be considered to be in motion. Motion applies to various phy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Petrolite
Petrolite Corporation was an American manufacturer of chemicals. Founded in 1930 from the merger of the Tret-O-lite Company with the Petroleum Rectifying Company of California (PETRECO), it was subsequently merged into Baker Hughes Incorporated in 1997. History Petrolite Corporation was founded from the work of two men, William S. Barnickel and Dr. Frederick G. Cottrell, who both invented ways to separate water from crude oil. Wet crude, known as ''roily oil'', was a non-profitable substance produced as a by-product of crude oil production. Most drilling companies would attempt to dispose of this wet crude by burning it in large fire pits, as there had been no successful process developed that could separate the water out of the wet crude. William Barnickel was born in St Louis, Missouri and studied chemistry. During his career, Barnickel worked in Sapulpa, Oklahoma, where he first began working on a way to separate water from crude oil. Barnickel believed that a simple chemic ...

9th Cir
9 (nine) is the natural number following and preceding . Evolution of the Arabic digit In the Brahmi numerals, beginning, various Indians wrote a digit 9 similar in shape to the modern closing question mark without the bottom dot. The Kshatrapa, Andhra and Gupta started curving the bottom vertical line coming up with a -look-alike. The Nagari continued the bottom stroke to make a circle and enclose the 3-look-alike, in much the same way that the sign @ encircles a lowercase ''a''. As time went on, the enclosing circle became bigger and its line continued beyond the circle downwards, as the 3-look-alike became smaller. Soon, all that was left of the 3-look-alike was a squiggle. The Arabs simply connected that squiggle to the downward stroke at the middle and subsequent European change was purely cosmetic. While the shape of the glyph for the digit 9 has an Ascender (typography), ascender in most modern typefaces, in typefaces with text figures the character usually has a desc ...
