Sky and its registered trademark have been the subject of a number of disputes in the last few years.  

The makers of new video game No Man's Sky announced today that they have reached agreement with Sky regarding its allegations that the videogame's title infringed its registered trademark.

As in this case, many trademark disputes settle on agreed terms rather than reaching contested court proceedings.  However, it is always better to ensure that your intellectual property is properly protected at the outset, and to be aware of potential infringements, rather than incurring the time and expense of a dispute later on.
