BlackBerry is Historical Archivessuing Snap Inc. for patent infringement.

Does that sound familiar? Well, you may be thinking of that time last month when the Canadian tech company sued Facebook Inc., alleging that massive social network improperly used its "mobile messaging intelligence" across Facebook, WhatsApp, and Instagram. 

Now, BlackBerry is going after Snapchat's parent company Snap Inc. The team at Snap is quite familiar with being brought in the same scope as Facebook, given the sheer number of times the tech giant has copied its product.

Bloomberg first reported the lawsuit on Tuesday. The lawsuit accuses Snap of infringing on six patents, addressing:

• Map Improvement for Mobile Devices

• User Interface Improvements for Mobile Devices

• Modern Mobile Advertising Techniques

Regarding map improvement, BlackBerry is referring to Snapchat's launch of Snap Maps.

Two of those six are in lawsuit BlackBerry filed against Facebook, according to Bloomberg.

A BlackBerry spokesperson sent the following emailed statement to Mashable:

“BlackBerry has a well-earned reputation for protecting and securing our customers’ data and privacy. For more than a year we have been working to establish a dialogue with Snap as we believe there are far more opportunities for partnership than disagreement. While we continue to hold this door open, we also have a strong claim that Snap infringed on our intellectual property, harmed our shareholders, and we have an obligation to pursue appropriate legal remedies."

Snap Inc. declined to comment on the lawsuit. According to a Snap spokesperson, the company hasn't yet reviewed the complaint.
