Seagate patent claim could spell trouble for PC industry

When Seagate Technology (NYSE: STX) made the claim recently that it holds a decent amount of patents related to the solid-state drive (SSD), there were probably some global tech firms cautiously fidgeting in their collective chairs. You see, Seagate is the world's largest hard drive company. Hard drives enable, well, everything from that laptop PC to the TiVo box at home to the classic iPod.

The deal is this, though: most hard drives use spinning platters that really do become a bottleneck in performance within the products those drives are located in. Samsung and other companies have been championing SSDs as a way to remove slower hard drives from products and replace them with computer chip storage devices that have no moving parts, don't heat up as much, use less power and are much faster in performance. That is, unless Seagate has patent claims to much of this platform, which is what it's claiming after buying a patent portfolio from Hewlett-Packard Corp. (NYSE: HPQ) years ago.

The first company under the gun is STEC, a manufacturer of SSDs. But the question of the hour is this: can one company actually patent the concept of an SSD, now that the technology itself is poised to start competing more heavily with traditional hard drive in everything from laptop PCs to set-top digital video recorders? Hard drives enable the growth of the PC market every quarter as well as a whole slew of other devices consumer snap up like hotcakes. Could Seagate own this universe shortly? It's being mum on its intentions, but if the company wants to become nasty about protecting its patents, it could become an even more powerful force in the storage industry than it already is.
