1. A hairdressing salon (1) comprising at least one styling station (3), which is embodied in a room (5), wherein the room (5) is arranged in a mobile structure (7), which can be displaced by means of a lifting tool, characterized in that the mobile structure (7) has at least one window (13).
How this application got through the EPO system is at the moment quite beyond me. From a quick review of the prosecution file though, it seems that the examiner was persuaded that adding a window made the invention allowable over US 2006/137188 A1. Just in case anyone has any doubt about whether the invention is novel, let alone inventive, there is prior art in the form of shipping containers repurposed as hair salons such as this article from 11 June 2011 (before the 23 August 2012 priority date of the patent), which describes the popular practice of converting shipping containers to new uses in South Africa. For further avoidance of doubt, the internet archive wayback machine (which is normally accepted by the EPO as evidence of publication date) confirms that the article was available on 16 June 2011. One of the photographs in the article, shown below, seems to have everything required according to claim 1. Incidentally, the search that led me to this took about five minutes.
The EPO will certainly not be able to do anything about this particular patent, at least not unless someone bothers to make the effort of opposing the patent (which they have until the end of May next year to do). The EPO might, however, like to take a look at how such an obviously invalid claim could get through a system that is considered to be the highest quality in the world.
UPDATE 22/11/16: Thank you to the anonymous commenter who has done a bit more research and come up with the following additional pieces of prior art, which at least demonstrate that the claimed invention can be considered to cover more than just shipping containers.
The first piece of prior art is Elizabeth Taylor's trailer for the 1963 film "Cleopatra". A report on this from 21 November 2011 is available here, from which the picture below is taken. The trailer obviously had a hairdressing salon, and windows. It was sold in 2012 for over $50k, according to this report, although it cost a lot more when it was made.
The second piece of prior art is a ship, specifically the "Radiance of the Seas", as shown in the video below being brought into drydock in the Bahamas. According to this article, the ship has a salon for "hair styling, facials and other beauty treatments".
