Apple is the biggest company in the world and with that comes its own set of problems. For example, generating over $50 billion in revenue in a single quarter is seen as a disappointment on Wall Street. It also means that you become a target for lawsuits of all kinds — both serious and spurious. While a court is yet to rule on it, a Florida man claiming $10 billion because he essentially invented the iPhone, iPod and iPad likely falls into the latter category.

Florida resident Thomas S. Ross filed a lawsuit against Apple this week claiming that a series of three drawings he made between 1992 and 1995 of an "electronic reading device" proves he came up with the ideas that would, 15 years later, see Apple launch the iPhone, iPod touch and the iPad.

The device outlined in the three hand drawn schematics includes dual rectangular panels with a touchscreen, cellular connectivity, internal and external storage and photo and video browsing — all things which would eventually be incorporated into smartphones.

There are some other aspects, however, which were never incorporated into most smartphones including a folding, dual-screen design, solar charging panels and a 3.5-inch diskette slot.

While Ross did initially file the drawings with the U.S. Patent and Trademark Office in November 1992 seeking a utility patent, because he failed to pay the required fees, the regulator declared the filing abandoned in 1995. Ross subsequently sought retroactive protection in 2014 filing the drawings with the U.S. Copyright Office. As well as the minimum payout of $10 billion, Ross is seeking a 1.5 percent royalty on infringing products.
