Re: Careful words
Regardless of Lord Justice Birss's carefully worded comment, he is still fundamentally wrong (in the long-term eyes of the law).
The topic was decided upon by the 2 opposite justices based upon the legal doctrine of person. Fundamentally, the potential issue is this: If the machine is granted the patents, and the patents are challenged at a future date, who exactly will come to defend the patent?
The machine won't, and can't, defend the patent in court because it is not [yet] an independently-thinking being. Any and all contest to the patents, if issues, would need to be defended by Dr. Thaler. The machine could not appear in court and take the witness box.
If a corporation is granted a patent a representative, granted power of attorney, by the legal structure of the corporation can appear in court as a proxy. A machine can't even grant a power of attorney as, not only does the machine not have that legal standing, the machine is not capable of the independent and self-aware thought processes necessary to make such a legal declaration stand up under any possible legal examination.
IMHO Dr. Thaler is trying to get his machines accepted for patent approval under the guise of expanding that legal umbrella in the future. I.e., he expects to be able to make his computational networks (which is all "AI" qualifies under at this point in history) work in other fields, and he expects to allow the machines to automatically claim the full legal rights of these creations with him getting the automatic benefits of things like licensing costs thanks to his ownership of the machines.
But that itself is a riddle, as an owned machine is not self-directing, forget self-actualizing. The only reason the machine is processing your calculations (again, at this point in history) is because you programmed it to do so. A human created the calculations, input the data structures, and hit the "Process" key. The fact that this complex machine did a huge number of calculations to transform the data set, maybe beyond the ability of the human programmer to instantly understand the outcome, did not grant that machine sentience and did not grant that machine self-awareness.
Come back in decades, maybe a century, to revisit this topic. It is not that, theoretically, a machine won't become sentient and self declaring. It is only we aren't to that point in development yet.
