I do research in computer science and in the last few years, lots of trivial and dumb patents in my field appeared out of nowhere. However, I can only assume that they really are trivial because they are written in a way to claim a lot without actually describing how any of it works. These patents have 0% information in them. What's more, they all read like a rewrite of papers that were published years ago (before th…
If the specification is not enabling and novel to one skilled in the art (much less obvious), then it is not valid. Under rexam or court proceedings they will be worth the paper they're printed on. That's an expensive way to determine things, but it sounds like that particular section of art at the patent office isn't doing much. On the other hand they only have to hide one novel idea and unique claim in the list to…
In my case, we submitted lots of prior art (some over 100 years old) to the court, and of course they shared this with the plaintiffs. I was certain we should be in the clear. However, in the time between receiving those documents and the actual court date, the plaintiffs submitted our list of prior art to the patent office as some sort of addendum. The patent office re-rubber stamped the new stack of paper, and the judge disregarded it during the trial. We lost. I doubt the patent office bothered to read, much less understand, any of it.
I feel very strongly that their patent was not novel, and since I wrote the algorithm which got us sued from scratch as a new college grad with only a bachelors degree, I doubt it was non-obvious to one skilled in the art. Maybe we could've won with better lawyers, but as a small startup, we didn't have that kind of money.
