HP Patents Bignum Implementation From 1912

I Don't Believe in Imaginary Property writes "The authors of GMP (the GNU Multiple Precision Arithmetic Library) were invited to join Peer-to-Patent to review HP's recent patent on a very old technique for implementing bignums because their software might infringe. Basically, HP's patent claims choosing an exponent based on processor word size. If you choose a 4-bit word size and a binary number, you end up working in hexadecimal. Or for a computer with a 16-bit word and a base-10 number, you use base 10,000 so that each digit of the base-10,000 number would fit into a single 16-bit word. The obvious problem with that is that there's plenty of prior art here. Someone who spent a few minutes Googling found that Knuth describing the idea in TAOCP Vol. 2 and other citations go back to 1912 (which implemented the same algorithm using strips of cardboard and a calculating machine). None of this can be found in the 'references cited' section. Even though the patent examiner did add a couple of references, they appear to have cited some old patents. The patent issued a few months ago was filed back in October of 2004, and collected dust at the USPTO for some 834 days."

In particular, is there any way sanity can enter the process without having to challenge it in court?

The whole idea is not that the patent has any basis but that it is ridiculously expensive to go to court. This puts a huge entry barrier around the market and protects the large incumbents. In essence, patents are now being used to protect large corporations from small entrepreneurs - exactly the opposite of their original intention.

Suggested standard for patent reviews

I'm not fundamentally against software patents, so long as they follow some basic rules:

• If prior art is found, but wasn't mentioned on the application, the person applying for the patent is shot.
• If finding that prior art took less than 2 hours of Googling by a PhD in the field, the inspector is shot.
• If all of the above are true, and the patent was asserted against someone, the lawyer is shot, and since corporations are "people", the entire corporation (if one was involved) is put in jail for its "lifetime" (e.g., until its incorporation is dissolved).
• A patent is considered "obvious" if 10 top-notch PhD's in the field are put into a room (with access to the Internet), posed with the problem to be solved, and can't come up with a solution similar to the one being proposed within a week.
• If a patent is overturned, whoever field the patent must pay all costs (including labor, and interest) to the person who did the work of getting it overturned. And must also participate in a last-man-standing cage match with Michael Tyson after having tatooed on his ass, "Mike Tyson, I'm going to make you my bitch!"
• Patents last for 7 years.

This would be completely acceptable to me.
