One of our clients received a complaint regarding the use of a interactive map. In this case Google maps with a markers overlay showing store locations. The patent https://data.epo.org/gpi/EP2336970B1-Interactive-electronically-presented-map seems to have a very broad definition of map interaction.
We did a rough investigative lookup for cases regarding this patent or mentions of this patent and it's implications on interactive maps on websites but without conclusive results. We expected more impact and discussions as a lot of websites use visualization of data using a map-tile provider combined with a data-layer.
We are wondering if anyone has come in contact with this patent before or is aware of any legal issues regarding this specific patent as it possibly has implications on a lot of our clients.

Update 2019/04/25 Somehow after a while they stopped harassing our client. We got to the point in which Google was, behind the screens, assisting us with proof of prior use etc but we never had to play this card. So for who gets into the same situation. Hang on, resist. They probably know they do not really have a solid case.
