Context: FSE Engineering Group Ltd (FSEE) (Chinese: 豐盛創建機電 工程有限公司)is the Electrical Engineering & Mechanical Engineering business company.  It was established in 1997 when its predecessor, NWS Engineering Group Ltd, sold out to Fung Seng Enterprises, It become a part of enterprise.  Now, FSE Engineering Group Ltd (FSEE) is the largest E&M Building Services engineering companies in Hong Kong Max Griggs is the president of the R Griggs Group, current owner of the Dr. Martens shoe company, and one of largest shoe manufacturers in the United Kingdom.  In 2002, the company ceased production in the United Kingdom and began outsourcing to China and Thailand. Solovair is a brand of British-made boots and footwear, produced by NPS Shoes Ltd., which was established in 1881.  NPS is based in Wollaston, Northamptonshire, an area known for its shoe industry.  NPS shoes are known for their Goodyear welt technology and use it in all their shoe production, this particular technique is needed to fix the Solovair sole onto "Soft Sole Suspension" boots and shoes.  Shoe manufacturer R. Griggs Group Ltd. had the patent to produce Dr. Martens boots but not the technology so in 1960 Griggs and NPS collaborated to create a boot using a Solovair sole and a Griggs boot, the result was the now iconic Dr. Martens boot.  The first pair left the NPS factory in 1960.  NPS Shoes continued to make Dr. Martens boots and shoes under licence until the mid 1990s.  They patented the name Solovair in 1995 and now make their own air-cushioned boot using the same lasts and leather cutters and machines used to create the first original Dr. Martens suspension soles in the UK. Dr. Martens is a British footwear and clothing brand, which also makes a range of accessories – shoe care products, clothing, luggage, etc.  In addition to Dr. Martens, they are also commonly known as Doctor Martens, Doc Martens, or Docs.  The footwear is distinguished by its air-cushioned sole (dubbed "Bouncing Soles"), upper shape, welted construction and yellow stitching.  The boots have been the choice of footwear among various groups in British culture: in the 1960s skinheads started to wear them, "Docs", being the usual naming, and by the late 1980s, they were popular among scooter riders, punks, some new wave musicians, and members of other youth subcultures. Boat shoes (also known as deck shoes) are typically canvas or leather with non-marking rubber soles designed for use on a boat.  A siping pattern is cut into the soles to provide grip on a wet deck; the leather construction, along with the application of oil, is designed to repel water; and the stitching is highly durable.  Boat shoes are traditionally worn without socks. Skate shoes or skateboard shoes are a type of footwear specifically designed and manufactured for use in skateboarding.  While numerous non-skaters choose to wear skate shoes, the design of the skate shoe includes many features designed especially for use in skateboarding, including a vulcanized rubber or polyurethane sole with minimal tread pattern or no pattern, a composition leather or suede upper, and double or triple stitching to extend the life of the upper material.  A low, padded tongue is often included for comfort. A Goodyear welt is a strip of leather, rubber, or plastic that runs along the perimeter of a shoe outsole.  The machinery used for the process was invented in 1869 by Charles Goodyear, Jr., the son of Charles Goodyear.  Time-consuming by modern standards , Goodyear welted construction is still considered one of the finest methods of shoe construction. Gravati is a family-owned company founded in 1909 that manufactures men's and women's dress shoes in Vigevano, Italy.  Although Gravati uses a variety of shoe construction methods, including Bologna and Goodyear construction, the majority of their production uses Blake construction.  The shoes are hand-crafted entirely within the factory by skilled artisans and technicians.  Every pattern of every Gravati shoe is hand-cut.  Unlike most modern shoe manufacturers, Gravati does not maintain stock—retailers must specify the patterns, lasts, leathers, soles, and construction methods that they want; and only then will the factory make the shoes.  Their production methods are typical of many upper-echelon shoemakers in that the uppers are cut (or clicked) and lasted and the shoes finished by hand, but that all sewing is done by machine. United States v. Glaxo Group Ltd., 410 U.S. 52 (1973), is a 1973 decision of the United States Supreme Court in which the Court held that (1) when a patent is directly involved in an antitrust violation, the Government may challenge the validity of the patent; and (2) ordinarily, in patent-antitrust cases, “[m]andatory selling on specified terms and compulsory patent licensing at reasonable charges are recognized antitrust remedies.” Hoof boots are commonly seen as a substitute to horseshoes, either as a backup for a thrown shoe when a farrier is not available, or as an alternative form of hoof protection for a barefoot horse.  Horse boots are used in all riding disciplines and are particularly popular for trail riding and endurance riding.  They are also used on horses in parades and on police horses who work on hard pavement.  Hoof boots may also be used when transitioning a horse from shod to unshod riding, or carried during a ride in case a horse throws a shoe.  In areas with persistently slippery conditions in winter, hoof boots are often used in combination with studs screwed into the soles.  This allows the horse to be ridden safely on slippery surfaces.  This must be done with a hoof boot with a sufficiently thick and inflexible sole to avoid bruising of the hoof sole.  Boots with soles that are too flexible are unsuitable for studding.
