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]
In contrast to the first jet with its delta wing configuration and forward canard wings, the second jet features a more conventional straight wing configuration with tapered leading and trailing edges. As you might expect, construction of the fuselage of the second jet is in many ways similar to that of the first, although in order to accommodate twin exhausts the rear isn’t tapered, and the air intakes which flank the fuselage are of a different design.
This set is designed for children aged 6+, and one of the ways that it is suitable for them is the inclusion of separate instruction booklets and numbered bags for the different parts of the set (see my post about LEGO age range suitability here).  A younger modeller can build the plane or other item of their choice as soon as they open the box. It's not so much one big set as 5 different parts which make a whole scene. My 7 year old son chose to build a jet first of all...
Primary concept and development work takes place at the Billund headquarters, where the company employs approximately 120 designers. The company also has smaller design offices in the UK, Spain, Germany, and Japan which are tasked with developing products aimed specifically at these markets. The average development period for a new product is around twelve months, split into three stages. The first stage is to identify market trends and developments, including contact by the designers directly with the market; some are stationed in toy shops close to holidays, while others interview children. The second stage is the design and development of the product based upon the results of the first stage. As of September 2008 the design teams use 3D modelling software to generate CAD drawings from initial design sketches. The designs are then prototyped using an in-house stereolithography machine. These prototypes are presented to the entire project team for comment and for testing by parents and children during the "validation" process. Designs may then be altered in accordance with the results from the focus groups. Virtual models of completed Lego products are built concurrently with the writing of the user instructions. Completed CAD models are also used in the wider organisation, for marketing and packaging.[33]
Agent 13 has a pretty plain appearance, with caramel-coloured wavy hair, and a black, spy-like top. Her torso has some nice details, with sharp, angular lines that all combine to form a rough outline of an upside down star. She has plain sand blue pants and rocks a sub-machine gun accessory. I like regular LEGO firearms, so it’s very nice to get one in this set as they’re fairly uncommon.
