Over the years, we’ve seen plenty of intellectual property lawsuits involving Apple Inc. (who, ahem, does not like to be called Apple, Inc.). Apple went after Digital Research and Microsoft during the ’80s and ’90s for copying the “look and feel” of the Macintosh OS. But in the last five years, Apple has initiated a flurry of litigation, commonly known as the mobile device patent wars, that is likely to have profound legal and historical significance.

The back-and-forth legal sparring has been largely between Apple and Samsung, with suits over both design and utility patents that have captivated the legal community, investors, and followers of software patent litigation. Below, we highlight some of the important milestones in this high stakes legal tussle.

  • April 15, 2011
    Apple files complaint in US District Court for the Northern District of California against Samsung for patent infringement of iPhone and iPad.
