MicroUnity was a major pioneer in the field of mediaprocessing. Unfortunately, it was ahead of its time and was killed by power and cost of media chips on the current process. Now its reduced to filing litigation against those who adopted similar designs on smaller processes.  (Source: MicroUnity)
Company is also suing Palm, Nokia, Motorola, HTC, LG, Qualcomm, Spring, and Texas Instruments

Apple's legal campaign against HTC has garnered a lot of attention.  It's widely perceived that Apple is trying to pick off smaller companies that make the Android handsets to kill the mobile operating system's momentum.  Apple's litigation centers around certain mobile hardware and interface patents Apple owns, such as a patent on mobile object oriented graphics, a patent on interrupt-based mobile processor undervolting, and a patent touch screen unlocking. 

Now Apple finds the tables have turned on it; a small company has filed suit against it, claiming that its devices infringe on a variety of hardware patents.  MicroUnity Systems Engineering is a small private company based in Santa Clara, California.  The company is adopting an equal opportunity approach, though, and is also suing 21 other companies, including Google, AT&T, Palm, Nokia, Motorola, HTC, LG, Qualcomm, Samsung, Spring, and Texas Instruments

The company may sound like a patent monger, but there's more to the story -- the firm actually was once home to some of the brightest engineering talent in the industry.  The company was founded by John Moussouris and Craig Hansen, two of the engineers who developed the now famous MIPS CPU microarchitecture.  The company functions primarily as a research and development firm and has a wealth of intellectual property.  In 2005 it received a $300M USD from Dell and Intel in a suit over some of its IP.  A similar suit against AMD and Sony over their GPUs was settled in 2007.

Microunity says that media processing technology inside handsets like the iPhone 3GS, iPod Touch, Motorola Droid, Palm Pre, Google Nexus One, and the Nokia N900 steals from its patented work.  MicroUnity says the 22 parties named in the suit violated the following patents it holds:

  • U.S. Patent No. 5,737,547, "System for Placing Entries of an Outstanding Processor Request into a Free Pool After the Request Is Accepted by a Corresponding Peripheral Device."

  • U.S. Patent No. 5,742,840, "General Purpose, Multiple Precision Parallel Operation, Programmable Media Processor."

  • U.S. Patent No. 5,794,061, "General Purpose, Multiple Precision Parallel Operation, Programmable Media Processor."

  • U.S. Patent No. 6,006,318 C1, "General Purpose, Dynamic Partitioning, Programmable Media Processor."

  • U.S. Patent No. 6,427,190, "Configurable Cache Allowing Cache-Type and Buffer-Type Access."

  • U.S. Patent No. 6,725,356 C1, "System with Wide Operand Architecture, and Method."

  • U.S. Patent No. 7,213,131, "Programmable Processor and Method for Partitioned Group Element Selection Operation."

  • U.S. Patent No. 7,216,217 B2, "Programmable Processor with Group Floating-Point Operations."

  • U.S. Patent No. 7,260,708 B2, "Programmable Processor and Method for Partitioned Group Shift."

  • U.S. Patent No. 7,353,367 B2, "System and Software for Catenated Group Shift Instruction."

  • U.S. Patent No. 7,509,366 B2, "Multiplier Array Processing System with Enhanced Utilization at Lower Precision."

  • U.S. Patent No. 7,653,806 B2, "Method and Apparatus for Performing Improved Group Floating-Point Operations."

  • U.S. Patent No. 7,660,972 B2, "Method and Software for Partitioned Floating-Point Multiply-Add Operation."

  • U.S. Patent No. 7,660,973 B2, "System and Apparatus for Group Data Operations."

Microunity developed technology in a number of fields including semiconductor processing, system design, chip architecture, software algorithms -- a rarity in the industry.  The company pioneered the mediaprocessor business, but ultimately saw its designs flop as at the time they consumed to much power and were too expensive.

The company's overreaching history earned it the nickname 
MicroLunacy in Silicon Valley.  While it was responsible for much innovation the flop of its mediaprocessors sent it reeling into consolidation.  The staff shrunk to 200 engineers and the company's chief business (until the patent litigation launched) was to sell a CAD tool that it sold in 1999.

One cannot help but appreciate the irony in Apple's case, but it's also interesting to note that MicroUnity, once an ambitious pioneer, has been reduced to trying to make a living off litigation.

Remembered, or created independently? This is one of the main questions people are asking here.

I'm honestly betting on 'created independently'. I recently was writing down ideas for stuff on paper, and someone told me "Wait a minute.... I think that thing already exists!" Took me online... yep, it already existed!

So, if I can come up with an idea for a product that ALREADY EXISTS and I didn't know it existed.. then a company with TONS of people definitely could do that.

That not necessarily true. It's a very common practice to reverse engineer an item for your own use. You just either hire an outside firm (there are several that specialize in this) or use a different company team (more risky). At the end you get a report worded in terms of general concepts of how it accomplishes the task and not the exact method and you give that to your team to jump start development. MANY projects actually prototype using the original devices and the prototype looks nothing like the desired end product (may be enormous and use boat loads of power for example), then you decide if it's worth it to RE the devices to accomplish your own goals. It's such a common practice the DMCA (piece of crap that it is) had to have exclusions to allow this common practice.
