If these weren't depressing they'd be funny. For those who don't know the patent & trademark office (PTO) defines "obvious" as described in a prior patent or, sometimes, an academic paper. Even if everybody in the field has been doing the same thing for years it isn't "non obvious" unless somebody wrote to the PTO about it. But since it's obvious in reality those nobody except crooks bother to.
The whole system is rigged in favor of "people" who write up patentable junk -- those who have the time to write it into patents -- whereas people who actually build things are busy perfecting the trade skills the patent system was made to protect.
OK - tirade over. Back to my new app. My wife dreamed it up and we're writing it together. When finished and released, if it does well, some fat slob -- who never wrote or programmed anything useful in his life -- will show up to shake us down.
