Five PC Vendors Face Patent Lawsuit 337
Combuchan writes "This article from internetnews.com caught my attention: While Linux lawsuits gobble up the IT community's mindshare, a lesser-known legal action is being fought seeking billions of dollars from five PC vendors. Patriot Scientific, a small, San Diego-based seller of embedded microprocessors for automotive and scientific applications, is suing Sony, Fujitu, Matsushita, Toshiba, and NEC, alleging infringement of a Patriot patent for what it calls 'fundamental microprocessor technology.'"

San Diego, CA - August 7, 2003 - - Patriot Scientific Corporation (OTCBB:PTSC) developer of key microprocessor technologies and scalable Java solutions for mobile products, today announced that it has received an additional patent for fundamental microprocessor technology currently in widespread use. United States Patent #6,598,148 B1 has been granted for PTSC's variable speed clock acceleration technology for RISC and CISC processors. The patented technology not only bolsters PTSC's licensable microprocessor IP portfolio, but further strengthens the company's patent rights.
Future patent grants are expected that will further expand PTSC's rights within these fundamental technologies.
Jim Turley, editor of Silicon-Insider and previous editor of Microprocessor Report and a member of the company's Scientific Advisory Board, said, "After analyzing PTSC's patent, I'm certainly impressed with its range of coverage, basically representing the dominant means of accelerating internal microprocessor clock speeds."
Jeff Wallin, president and CEO of PTSC stated, "This is an important patent grant as it further validates our early innovation of key processing technologies that are ensconced in our IP portfolio. It not only gives our customers an extra measure of certainty in terms of our virginity and the technology but it substantially strengthens the validity and scope of our patent enforcement efforts."
Because of the breadth of the company's patent portfolio coupled with the size of the market benefiting from the company's protected technologies, the company is pursuing an intellectual property compliance program targeted at hundreds of companies using microprocessors with internal capabilities greater than 120 KHz. This is estimated to be in excess of a $200 billion market. Beatie and Osborn LLP, one of America's most prestigious law firms, represents the company's licensing and enforcement objectives.

To these companies, owning lots of patents on lots of sometimes crazy things is a way of protecting their turf and a good way of putting potential competitors out of business. If they try to tighten up U.S. patent law, they'll only be making their job harder. Besides, I imagine that the amount of money they lose off most these lawsuits is chicken-scratch compared to their coffers.

Please remember that titles, abstracts, and descriptions from the patent mean nothing legally. The only section which has any legal weight is the claims, so please don't start complaining about old microprocessors as "prior art" unless they actually do the same thing as is stated in the claims.

Who invented the Pentium? (Score:5, Informative)
I don't know when the first Pentium came out with an on-chip clock, but that's probably not important anyway. I doubt if the patent is on the idea of an on-chip clock -- they can hardly claim to be the first people to have invented the concept of component integration! More likely they're claiming to have invented a design or manufacturing technique... oh well, might as well go look it up.
Yup, here's the 1995 patent application [uspto.gov]. It's too complicated for me, but they seem be claiming that their design manages to produce a steady clock signal even as temperature fluctuations play holy hell with the oscillations that produce the clock signal. Assuming I haven't totally mangled the concept, and that they really did think of this first, that's a pretty significant invention. It's certainly not on the same level as these business-process and software patents that we all love to hate.

any single chip static microcontroller that incorporates a substantial amount of RAM on chip, has bufferred memory access, and can run at multiple clock speeds fits the description in this claim. I think some versions of Mitsubishi M16 Hitachi H8 had enough RAM to cover more than half the chip and existed as early as 1996. This patent probably is bogus.
Claim 1:
1. A microprocessor integrated circuit comprising:
a program-controlled processing unit operative in accordance with a sequence of program instructions;
a memory coupled to said processing unit and capable of storing information provided by said processing unit;
a plurality of column latches coupled to the processing unit and the memory, wherein, during a read operation, a row of bits are read from the memory and stored in the column latch; and
a variable speed system clock having an output coupled to said processing unit;
said processing unit, said variable speed system clock, said plurality of column latches, and said memory fabricated on a single substrate, said memory using a greater area of said single substrate than said processing unit, said memory further using a majority of a total area of said single substrate.

It is also important to note that dependent claims (for example, a claim that starts like "The apparatus of claim 1") contain every limitation of the claims that they depend on.
Techincally, for something to be prior art, the only requirement is that it have existed prior to the filing of the application. For something to be considered good prior art, then it will have to read on the claims in some way.
Good prior art can read on all, or some of the features of a single claim depending on which statute it is being used under. For prior art under 35 USC 102, the prior art must have (at least) every feature of the claims. For prior art under 35 USC 103 a single prior art reference does not have to have every feature of the claims, however it must be combined with additional references which have the missing features and give motivation to add the missing features into the first reference to acheive the system (method, apparatus, etc..) of a single claim.
