Legal threads things that ought not to be threaded. I read patents for "innovations" for which the proposed solution is trivial -- something I might have done quite by accident as a Junior in college -- and for which no other solution will suffice. These are patents that have made it through the process. It makes me afraid to write code, lest I accidentally infringe! But somebody's legal department (possibly my company's) kept someone from censoring him/herself, as you say, and now there is a bogus patent.
While I understand your frustration with patents that are probably only incrementally meaningful, I must strenuously "traverse" your use of the word "bogus".
As I've stated before it is quite a common and actually quite solid business strategy to _cross license_ with other companies, even competitors.
Now this is _not_ a "bogus" patent, even if it is technically "under" another patent.
It is quite legitimate to get a patent that is valid but cannot be practiced by the assignee of the patent, but the patent is valid nonetheless.
One of my coworkers likes to tell the story of how, years ago, he implemented a mathematical solution to a problem published in a 50-year-old textbook. He was subsequently told that his solution infringed on a competitor's patent, and that he would have to change the algorithm. Could his (giant) company have invalidated the patent? Probably.
Mmmmm, not necessarily. Remember it is hard to invalidate a patent since there is an assumption of validity of the patent (35USC Section 282, I believe). So if the original patent was well drafted it would be harder to invalidate that simply because the "giant" corporation had more money. But you may be quite correct, with enough money the legal department might have been able to do so.
But the law is set up to ensure that once granted a patent is not easily invalidated. I've seen lawyers of big companies indicate that they don't want to go down that aisle unless they absolutely have to.
But it had been granted, and now it was cheaper to make my coworker recode the solution in a sub-optimal way than to invalidate it. If a major corporation is afraid to fight bogus patents, what hope do small companies have?
Was it a "bogus" patent? If it was bogus it would be no problem to invalidate.
Legal is the wrong department to be deciding what is obvious or no.
As I said, I wasn't sure if "Obviousness" was a matter for legal. Certainly there are topics within IP that only legal can, technically speaking, deal with in corporate settings in order to limit liability.
However, the idea of what is obvious or not should, reasonably, be within the realm of those most familiar with the relevant art.
and they have an incentive to err (and err very far) on the side of submission.
In a world where corporations have an infinite amount of money, perhaps but that is not really always the case. Usually Legal wants to ensure that the money budgeted to them for filing cases and prosecuting them is going to be a payback. Of course I don't think they work in isolation, the scientists also have a say in many if not most cases to help Legal determine if this is a realistic stance for patentability.
In certain areas, where it is very crowded art it is often impossible to get broad patents but are limited to small, narrow coverage, but the coverage of the whitespace is quite necessary.
Again, I'm not defending "bogus" patents, but I am defending narrow patents which are valid. And those exist.
It is precisely the mathematicians, and scientists, and engineers that ought to decide whether something is obvious or whether it is a candidate for submission.
According to the MPEP (2141) "obviousness is a question of law" utilizing the "Graham factors". So it is not merely for the scientists to decide. However, I am not a lawyer so I simply assume that professional scientists, mathematicians, engineers etc are heavily relied upon when Obviousness comes up for discussion within a patent prosecution. However according the MPEP obviousness is a "legal conclusion". But also remember that any given examiner who is responsible for making the determination is usually a degreed scientist in the area they are examining in within the USPTO.
Again, I'm not a lawyer nor have I been directly involved in any prosecutions other than watching some of my applications be prosecuted from a distance.
