The definitive shape of the Lego bricks, with the inner tubes, was patented by the Lego Group in 1958.[15][56] Several competitors have attempted to take advantage of Lego's popularity by producing blocks of similar dimensions, and advertising them as being compatible with Lego bricks. In 2002, Lego sued the CoCo Toy Company in Beijing for copyright infringement over its "Coko bricks" product. CoCo was ordered to cease manufacture of the products, publish a formal apology and pay damages.[57] Lego sued the English company Best-Lock Construction Toys in German courts in 2004[58] and 2009;[59] the Federal Patent Court of Germany denied Lego trademark protection for the shape of its bricks for the latter case.[60] In 2005, the Lego Company sued Canadian company Mega Bloks for trademark violation, but the Supreme Court of Canada upheld Mega Bloks' rights to sell their product.[61] In 2010, the European Court of Justice ruled that the eight-peg design of the original Lego brick "merely performs a technical function [and] cannot be registered as a trademark."[62]

Almost all major European carriers have a connection to Copenhagen from their main hubs. As Denmark holds sizable immigrant communities from various European countries, even smaller carriers have frequent connections to the likes of Sarajevo or Belgrade. Copenhagen Airport has been seeing increased traffic from low-fare carriers since the launch of the dedicated CPH Go section of the airport (with common check-in and security with other airlines, but separate gates and waiting area). Airlines using CPH Go include EasyJet, Ryanair, Transavia, and WizzAir, although the latter only for selected destinations, with the majority of its flights to the Øresund area landing at Malmö Sturup Airport instead.

There are several robotics competitions which use the Lego robotics sets. The earliest is Botball, a national U.S. middle- and high-school competition stemming from the MIT 6.270 Lego robotics tournament. Other Lego robotics competitions include Junior FIRST LEGO League (Jr.FLL) for students ages 6–9 and FIRST Lego League (FLL) for students ages 9–16 (age 9–14 in the United States, Canada, and Mexico). Jr.FLL and FLL offer real-world engineering challenges to participants. FLL uses Lego-based robots to complete tasks. Jr.FLL participants build models out of Lego elements. In its 2010 season, there were 16,070 FLL teams in over 55 countries. In its 2010 season, there were 2,147 Jr.FLL teams with 12,882 total student participants in the United States and Canada. The international RoboCup Junior football competition involves extensive use of Lego Mindstorms equipment which is often pushed to its extreme limits.[53]
Since 1963, Lego pieces have been manufactured from a strong, resilient plastic known as acrylonitrile butadiene styrene (ABS).[12][30] As of September 2008, Lego engineers use the NX CAD/CAM/CAE PLM software suite to model the elements. The software allows the parts to be optimised by way of mould flow and stress analysis. Prototype moulds are sometimes built before the design is committed to mass production. The ABS plastic is heated to 232 °C (450 °F) until it reaches a dough-like consistency. It is then injected into the moulds at pressures between 25 and 150 tonnes, and takes approximately 15 seconds to cool. The moulds are permitted a tolerance of up to twenty micrometres, to ensure the bricks remain connected.[33] Human inspectors check the output of the moulds, to eliminate significant variations in colour or thickness. According to the Lego Group, about eighteen bricks out of every million fail to meet the standard required.[37] Lego factories recycle all but about 1 percent of their plastic waste from the manufacturing process. If the plastic cannot be re-used in Lego bricks, it is processed and sold on to industries that can make use of it.[38][39] Lego has a self-imposed 2030 deadline to find a more eco-friendly alternative to the ABS plastic it currently uses in its bricks.[40]
Billund Airport had its beginning in 1961 when the son of the founder of the Lego Group, Godtfred Kirk Christiansen, established a private 800-meter long runway and hangar north of his factory in Billund. With Christiansen as a key driver, more of the neighbouring municipalities were included in the group of owners, and it was planned that the airport should be expanded to a regular public airport.

This is a good set if you want an airport. The set includes a big plain and a terminal. The terminal has a control tower, check-in, luggage handler, fuel tank, ... I expanded my terminal and built it on a 32x32 baseplate and used the 2 grey 16x16 plates for the roof. The backside is not completely closed. Otherwise is the luggage belt is not accessible with my hand. I added 2 extra seats in the plane. Normally you have 6 seats in the plane, but I raised it to 8. I wanted more than 8 but that is almost not possible. The plane is brought with a big brick which includes the middle of the plane and the 2 wings and that one limits the possibilities. The toilet in the plane is still on the backside.
I purchased this set the day it was released for my LEGO City, as an upgrade from my previous airport (10159 Airport from 2004). First off, the build is great and although it's not very challenging, it's exciting to see the plane come to life and the use of the big plane pieces (eg. the nose, the wings, the tail etc.) was new to me, though I know there have been a number of planes in the past that use these pieces. There are 4 instruction booklets (2 for the plane, one for the airport, and one for the luggage/fuel/stairs car), 8 numbered bags, and two separate bags with the bigger pieces in. This makes the build very easy to follow. The completed set is very grand (especially the plane) in scale, and great looking. It's nice to see that a different colour scheme been used for the plane as opposed to the usual red and white or blue and white colours as seen in previous sets. The plane is HUGE, with a wingspan of around 2 32-wide baseplates (bare this in mind if you want to make a runway). However, despite its huge size, the inside of the plane is very bare. There are 5 seats for the passengers, another one facing backwards which I presume is for the cabin crew (although there isn't a cabin crew minifigure, which would have been a nice addition), and two seats in the cockpit. There's a tiny bathroom at the back of the plane, and a small galley area at the front with a sink and cupboard. There's easily room for a sixth chair in the plane, which I think should have been included, and the space within the plane could've been arranged better to fully optimise the area. The airport terminal has a very nice modern look, and includes the revolving door, tower, waiting area, security scanner and check in desk with luggage conveyor. Although this sounds like a lot of features, the inside of the terminal is, again, very bare and the space could've been used better. There are only 4 seats in the waiting area, and a lot of the space is taken up by the revolving door. The operational conveyor belt for the luggage is a nice touch, though, and there is a fair bit of playability within. The service car is a nice addition to this set and gives it more playability. All the trailers (fuel, stairs and luggage) connect together and attach to the service car, which has a really cool "follow me" sign on the back. This is a really nice addition to the set. Overall, I really like this set because of how it looks and because there's plenty of opportunity for play, but I think a lot more thought could've gone into maximising the space within the plane and the airport. Some more minifigures would have been good, such as a member of the cabin crew, a check-in clerk and a security officer. The value for money is okay with this set, as you do get a lot of big pieces, but the bare interiors are a little disappointing for the price you pay.
The set contains six minifigures. Even though they all incorporate standard, unprinted minifigure legs together with commonly-available headprints, it appears that all six are unique to the set. First up are two members of the Ground Crew (below). The bearded guy has an orange torso printed with a hi-viz jacket, ID badge and red pen pattern. This has appeared in nine sets to date including all of the 2016 Airport sets plus 60080 Spaceport which I reviewed here last summer. His red construction helmet, which incorporates a pair of non-removable black ear muffs, has appeared in less than ten sets to date. The other member of the ground crew has a rather nice printed medium blue torso which is new this year and has only appeared in a total of three sets including this one. It features a shirt print which includes the Octan logo and a top pocket complete with a pen.

The Lego Group's motto is det bedste er ikke for godt which means roughly "only the best is the best" (more literally "the best is never too good").[8] This motto, which is still used today, was created by Christiansen to encourage his employees never to skimp on quality, a value he believed in strongly.[8] By 1951 plastic toys accounted for half of the Lego company's output, even though the Danish trade magazine Legetøjs-Tidende ("Toy-Times"), visiting the Lego factory in Billund in the early 1950s, felt that plastic would never be able to replace traditional wooden toys.[13] Although a common sentiment, Lego toys seem to have become a significant exception to the dislike of plastic in children's toys, due in part to the high standards set by Ole Kirk.[14]

Since around 2000, the Lego Group has been promoting "Lego Serious Play", a form of business consultancy fostering creative thinking, in which team members build metaphors of their organizational identities and experiences using Lego bricks. Participants work through imaginary scenarios using visual three-dimensional Lego constructions, imaginatively exploring possibilities in a serious form of play.[73]
