Quantum Computing Patents (part 2)

Filed under: Uncategorized — rrtucci @ 2:45 am

In my previous post, I spoke about QC patents in general. In this post, I will say a few things about my own personal experience with QC patents. I find writing patents very dull and tedious, because you have to re-edit them over and over again, trying to fill in all the loopholes. Nevertheless, I file them anyway because I realize investors expect them, and I have this crazy hope that someday I’ll start a QC software company.

I recently submitted two QC patent applications:

  • “Method for Sampling Probability Distributions Using a Quantum Computer”
    Claims and specification here. Figures 1-5 here. Figures 6-12 here.

  • “Method for Driving Starting Quantum State to Target One”
    Claims and specification here. Figures 1-5 here.

I am also currently writing a patent for my Ziti functions paper. I also have 3 other quantum computing patents, already granted. My QC patents are all primarily software patents.

I believe that software patents are just and beneficial and should be allowed. I’ve explained why I believe so in an essay entitled “In Defense of Software Patents”. I respect the opinions of those who disagree with me about this, but I don’t want to argue about it in this blog. I’m very turned off by those who see the policy question of whether to allow or not software patents as a titanic battle between the forces of good and evil.

Addendum (Nov. 1, 2010): Finished and filed a patent on my Ziti functions paper:

  • “Method for Evaluating Quantum Operator Averages”, by R.R. Tucci, Claims and specification here. Figures 1 to 4 and 6 here, Figure 5 here

All my patents, both granted and pending, can be viewed here

  2. No need to be a nutcase like Stallman to find software patents ridiculous but for you it is not so much a matter of disagreement than a matter of risk!
    Relying on software patents for your business plans can be dangerous, previous legal fashion may come back, and though they use them big players like Oracle an IBM are against software patents, remember…
    Also, for “speculative” fields like QC your patents may die of obsolescence before being exploitable.

  3. Dear Rrtucci,

    I´ve read your 2006 comment on patents and i agree on almost everything.

    I find that your position regarding some pharmaceuticals is not consistent with the rest of the article (in fact i´m more pro-patent than you): based on what principle should the government force the holder to reduce the price ? What the government can do is to pay for the price, and in this case we (all the taxpayer) pay for it. Voters will decide on this issue; i would even vote in favour of it since i´m sensible to this problem; but i find unfair that the patent holder pays for it.

    Also i find the patent system very close to communism: the property they give to the holder is limited, again based on an unjustified principle. I know the patent holder knows the rules and accept to play the game, but this kind of limited property is quite similar to communism IMO…

    You explicitly says you do not want to discuss these issues in this blog and i respect your position, so pls feel free to comment on above or not. On the other hand i´m highly interested in knowing answers to bellow questions.

    Where did you get the figure in your previous post, of 95% of patents ending in nothing but loses to the holder ?

    How much time did it took for your applications to be granted after their publication. The official delay is 6 months, but in my experience it can take more time. Just to check other experiences.

    Thanks and good luck with your patents !

  4. “Where did you get the figure in your previous post, of 95% of patents ending in nothing but loses to the holder ?”

    I’m just guessing.

    “How much time did it took for your applications to be granted after their publication. The official delay is 6 months, but in my experience it can take more time. Just to check other experiences.”

    Unfortunately, the US patent system is very slow and inefficient, IMHO. My experience is that it sometimes takes as long as 3 years before you get the “first office action”. After that, it goes a little faster.

    I wish that the USPTO accepted patent applications in LaTex and that they published those applications the next day in pdf form . This is what arXiv does with papers.

  5. I recently read an excellent essay on software patents that I recommend highly:

    Are Software Patents Evil?” by Paul Graham

  6. 95%, Ok. I´ve heard this information with similar figures several times before and i supposed they must come from a common source.

    About 3 years. ok. I´ve read (see in bellow blog) that the number employees of USPTO increased from around 6000 to around 10000 recently. The number of patent applications should have increased much more then since there are still big gaps from the official to actual delay.

    I will read the essay you suggest. There is an anti-IP blog i follow from time to time( http://www.againstmonopoly.org/ )and a center of study (again anti-IP: http://c4sif.org/) stablished by one of the authors of this blog. Even if i desagree with almost all of their biased posts, they are a good source of information about IP issues; pro-IP people seems to be shy defending their position or just pass…i could not find any similar blog from them.

    Thanks much !
